  • Flat File Connection Manager in SSIS package shows "Valid File Name Must be Selected"

    - by Traples
    (Flat File Location) Samba Share | Windows Share (SSIS) _______________________________ | | XP 32bit | Works | Works | | 2003 Serv 32bit | Works | Works | | Vista 64bit | ERROR | Works | | Win 7 64bit | ERROR | Works | | 2008 Serv 64bit | ERROR | Works I created an SSIS package in VS 2008 that parses a flat file from a shared folder and puts the records into a SQL Server db. I recently installed Windows 7 and VS 2008 on a new workstation. When I import the package from TFS and open it, I get the error Validation error. Parse and Import Catalog Flat File: MySSISPackage: The file name "\\shared\flatfile.txt" specified in the connection was not valid. When I open the Flat File Connection Manager Editor, there is an error stating: A valid file name must be selected I can browse to and select the file from inside the editor, but I cannot change any properties, or move away from the General tab because of this error. If I go back to my laptop (Windows XP), where the package was first created, there is no error. Both workstations are on the same domain, and I'm logging in using the same credentials. Any ideas as to why I would receive this error from one workstation and not another? UPDATE: If I take the .dtsx package from the running workstation and load it into SSIS on the server, I get the following errors when it tries to run: Error: The file name "\\shared\flatfile.txt" specified in the connection was not valid. and... Error: Connection "MySSISPackage" failed validation. and... Error: The file name property is not valid. The file name is a device or contains invalid characters. UPDATE 2: a) The Shared folder I'm trying to pull the flat file from is a Samba share on a Unix box. b) If I access the file using SSIS on any 64-bit platform (Windows 7 64-bit, Vista 64-bit, Windows Server 2008) I get the error "A valid file name must be selected." c) Accessing the file using SSIS from 32-bit environments (Windows XP 32-bit, Windows Server 2003 32-bit) there is no problem. d) If I move the file to a shared folder on a Windows server, 64-bit SSIS recognizes the file.

  • Should I add the vcxproj.filter files to source control

    - by jschroedl
    While evaluating Visual Studio 2010 Beta 2, I see that in the converted directory my vcproj files have become vcxproj files. There are also vcxproj.filter files alongside each project which appear to contain a description of the folder structure (\Source Files, \Header Files, etc.). Do you think these filter files should be kept per-user or should the be shared across the whole dev group and checked into SCC? My current thinking is to check them in but wondered if there's any reasons not to do that or perhaps good reasons that I should definitely check them in. The obvious benefit is that the folder structures will match if I'm looking at someone else's machine but maybe they'd like to reorganize things logically??

  • How do I use a relative path in XDocument.Load?

    - by PaulC
    I have an XML file named PageData.xml in my App_Data folder. I want to populate an XDocument with this file using XDocument.Load. If I supply the full physical path it works, i.e.: XDocument vXDoc = XDocument.Load("/Work/Project/Web/100413 Dev/App_Data/PageData.xml"); ...where "Work" is a folder on my C: drive. If I try a relative path like this, though, I get a DirectoryNotFoundException: XDocument vXDoc = XDocument.Load("AppData/PageData.xml"); "Could not find a part of the path 'C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\10.0\AppData\PageData.xml'." This is obviously wrong, but there must be an easy way to set the correct relative path? What am I overlooking? Your help is appreciated.

  • Can I read an Outlook (2003/2007) PST file in C#?

    - by Andy May
    Is it possible to read a .PST file using C#? I would like to do this as a standalone application, not as an Outlook addin (if that is possible). If have seen other SO questions similar to this mention MailNavigator but I am looking to do this programmatically in C#. I have looked at the Microsoft.Office.Interop.Outlook namespace but that appears to be just for Outlook addins. LibPST appears to be able to read PST files, but this is in C (sorry Joel, I didn't learn C before graduating). Any help would be greatly appreciated, thanks! EDIT: Thank you all for the responses! I accepted Matthew Ruston's response as the answer because it ultimately led me to the code I was looking for. Here is a simple example of what I got to work (You will need to add a reference to Microsoft.Office.Interop.Outlook): using System; using System.Collections.Generic; using Microsoft.Office.Interop.Outlook; namespace PSTReader { class Program { static void Main () { try { IEnumerable<MailItem> mailItems = readPst(@"C:\temp\PST\Test.pst", "Test PST"); foreach (MailItem mailItem in mailItems) { Console.WriteLine(mailItem.SenderName + " - " + mailItem.Subject); } } catch (System.Exception ex) { Console.WriteLine(ex.Message); } Console.ReadLine(); } private static IEnumerable<MailItem> readPst(string pstFilePath, string pstName) { List<MailItem> mailItems = new List<MailItem>(); Application app = new Application(); NameSpace outlookNs = app.GetNamespace("MAPI"); // Add PST file (Outlook Data File) to Default Profile outlookNs.AddStore(pstFilePath); MAPIFolder rootFolder = outlookNs.Stores[pstName].GetRootFolder(); // Traverse through all folders in the PST file // TODO: This is not recursive, refactor Folders subFolders = rootFolder.Folders; foreach (Folder folder in subFolders) { Items items = folder.Items; foreach (object item in items) { if (item is MailItem) { MailItem mailItem = item as MailItem; mailItems.Add(mailItem); } } } // Remove PST file from Default Profile outlookNs.RemoveStore(rootFolder); return mailItems; } } } Note: This code assumes that Outlook is installed and already configured for the current user. It uses the Default Profile (you can edit the default profile by going to Mail in the Control Panel). One major improvement on this code would be to create a temporary profile to use instead of the Default, then destroy it once completed.

  • How to add SQLite (SQLite.NET) to my C# project

    - by Lirik
    I followed the instructions in the documentation: Scenario 1: Version Independent (does not use the Global Assembly Cache) This method allows you to drop any new version of the System.Data.SQLite.DLL into your application's folder and use it without any code modifications or recompiling. Add the following code to your app.config file: <configuration> <system.data> <DbProviderFactories> <remove invariant="System.Data.SQLite"/> <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /> </DbProviderFactories> </system.data> </configuration> My app.config file now looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="DataFeed.DataFeedSettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> </sectionGroup> </configSections> <userSettings> <DataFeed.DataFeedSettings> <setting name="eodData" serializeAs="String"> <value>False</value> </setting> </DataFeed.DataFeedSettings> </userSettings> <system.data> <DbProviderFactories> <remove invariant="System.Data.SQLite"/> <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /> </DbProviderFactories> </system.data> </configuration> My project is called "DataFeed": using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data.SQLite; //<-- Causes compiler error namespace DataFeed { class Program { static void Main(string[] args) { } } } The error I get is: .\dev\DataFeed\Program.cs(5,19): error CS0234: The type or namespace name 'SQLite' does not exist in the namespace 'System.Data' (are you missing an assembly reference?) I'm not using the GAC, I simply dropped the System.Data.SQLite.dll into my .\dev\DataFeed\ folder. I thought that all I needed to do is add the DLL to the project folder as it was mentioned in the documentation. Any hints on how to actually make this work?

  • How to compile x64 asp.net website?

    - by Eran Betzalel
    I'm trying to compile (using Visual Studio) an ASP.Net website with the Chilkat library. The compilation fails due to this error: Could not load file or assembly 'ChilkatDotNet2, Version=9.0.8.0, Culture=neutral, PublicKeyToken=eb5fc1fc52ef09bd' or one of its dependencies. An attempt was made to load a program with an incorrect format. I've been told that this error occurs because of platform noncompliance. The weird thing is that although the compilation fails, the site works once accessed from a browser. My theory is that the IIS compilation uses csc.exe compiler from the Framework64 (64 bit) folder while the Visual Studio uses csc.exe compiler from the Framework (32 bit) folder. If this is acually it, how can I configure my Visual studio to run with the 64 bit compiler for ASP.Net sites? This is my current development configuration: Windows 7 (x64). Visual Studio 2008 Pro (x86 of course...). Chilkat library (x64) IIS/Asp.net (x64).

  • Fail to launch application (CreateProcess error=87), can't use shorten classpath workaround

    - by Ivo Bosticky
    When I launch our application in Eclipse on Windows I receive the following error: Exception occured executing command line. Cannot run program .. : CreateProcess error=87, The parameter is incorrect I've solved this in the past by shortening the CLASSPATH. I've now come to a point where I can no longer shorten the CLASSPATH, and would like to know if there are any other workarounds. http://support.microsoft.com/kb/830473 seems to indicate that the max command prompt line length in windows xp is 8191 characters, and the only solution is to shorten folder names, reduce depth of folder trees, using parameter files, etc.

  • C# Neural Networks with Encog

    - by JoshReuben
    Neural Networks ·       I recently read a book Introduction to Neural Networks for C# , by Jeff Heaton. http://www.amazon.com/Introduction-Neural-Networks-C-2nd/dp/1604390093/ref=sr_1_2?ie=UTF8&s=books&qid=1296821004&sr=8-2-spell. Not the 1st ANN book I've perused, but a nice revision.   ·       Artificial Neural Networks (ANNs) are a mechanism of machine learning – see http://en.wikipedia.org/wiki/Artificial_neural_network , http://en.wikipedia.org/wiki/Category:Machine_learning ·       Problems Not Suited to a Neural Network Solution- Programs that are easily written out as flowcharts consisting of well-defined steps, program logic that is unlikely to change, problems in which you must know exactly how the solution was derived. ·       Problems Suited to a Neural Network – pattern recognition, classification, series prediction, and data mining. Pattern recognition - network attempts to determine if the input data matches a pattern that it has been trained to recognize. Classification - take input samples and classify them into fuzzy groups. ·       As far as machine learning approaches go, I thing SVMs are superior (see http://en.wikipedia.org/wiki/Support_vector_machine ) - a neural network has certain disadvantages in comparison: an ANN can be overtrained, different training sets can produce non-deterministic weights and it is not possible to discern the underlying decision function of an ANN from its weight matrix – they are black box. ·       In this post, I'm not going to go into internals (believe me I know them). An autoassociative network (e.g. a Hopfield network) will echo back a pattern if it is recognized. ·       Under the hood, there is very little maths. In a nutshell - Some simple matrix operations occur during training: the input array is processed (normalized into bipolar values of 1, -1) - transposed from input column vector into a row vector, these are subject to matrix multiplication and then subtraction of the identity matrix to get a contribution matrix. The dot product is taken against the weight matrix to yield a boolean match result. For backpropogation training, a derivative function is required. In learning, hill climbing mechanisms such as Genetic Algorithms and Simulated Annealing are used to escape local minima. For unsupervised training, such as found in Self Organizing Maps used for OCR, Hebbs rule is applied. ·       The purpose of this post is not to mire you in technical and conceptual details, but to show you how to leverage neural networks via an abstraction API - Encog   Encog ·       Encog is a neural network API ·       Links to Encog: http://www.encog.org , http://www.heatonresearch.com/encog, http://www.heatonresearch.com/forum ·       Encog requires .Net 3.5 or higher – there is also a Silverlight version. Third-Party Libraries – log4net and nunit. ·       Encog supports feedforward, recurrent, self-organizing maps, radial basis function and Hopfield neural networks. ·       Encog neural networks, and related data, can be stored in .EG XML files. ·       Encog Workbench allows you to edit, train and visualize neural networks. The Encog Workbench can generate code. Synapses and layers ·       the primary building blocks - Almost every neural network will have, at a minimum, an input and output layer. In some cases, the same layer will function as both input and output layer. ·       To adapt a problem to a neural network, you must determine how to feed the problem into the input layer of a neural network, and receive the solution through the output layer of a neural network. ·       The Input Layer - For each input neuron, one double value is stored. An array is passed as input to a layer. Encog uses the interface INeuralData to hold these arrays. The class BasicNeuralData implements the INeuralData interface. Once the neural network processes the input, an INeuralData based class will be returned from the neural network's output layer. ·       convert a double array into an INeuralData object : INeuralData data = new BasicNeuralData(= new double[10]); ·       the Output Layer- The neural network outputs an array of doubles, wraped in a class based on the INeuralData interface. ·        The real power of a neural network comes from its pattern recognition capabilities. The neural network should be able to produce the desired output even if the input has been slightly distorted. ·       Hidden Layers– optional. between the input and output layers. very much a “black box”. If the structure of the hidden layer is too simple it may not learn the problem. If the structure is too complex, it will learn the problem but will be very slow to train and execute. Some neural networks have no hidden layers. The input layer may be directly connected to the output layer. Further, some neural networks have only a single layer. A single layer neural network has the single layer self-connected. ·       connections, called synapses, contain individual weight matrixes. These values are changed as the neural network learns. Constructing a Neural Network ·       the XOR operator is a frequent “first example” -the “Hello World” application for neural networks. ·       The XOR Operator- only returns true when both inputs differ. 0 XOR 0 = 0 1 XOR 0 = 1 0 XOR 1 = 1 1 XOR 1 = 0 ·       Structuring a Neural Network for XOR  - two inputs to the XOR operator and one output. ·       input: 0.0,0.0 1.0,0.0 0.0,1.0 1.0,1.0 ·       Expected output: 0.0 1.0 1.0 0.0 ·       A Perceptron - a simple feedforward neural network to learn the XOR operator. ·       Because the XOR operator has two inputs and one output, the neural network will follow suit. Additionally, the neural network will have a single hidden layer, with two neurons to help process the data. The choice for 2 neurons in the hidden layer is arbitrary, and often comes down to trial and error. ·       Neuron Diagram for the XOR Network ·       ·       The Encog workbench displays neural networks on a layer-by-layer basis. ·       Encog Layer Diagram for the XOR Network:   ·       Create a BasicNetwork - Three layers are added to this network. the FinalizeStructure method must be called to inform the network that no more layers are to be added. The call to Reset randomizes the weights in the connections between these layers. var network = new BasicNetwork(); network.AddLayer(new BasicLayer(2)); network.AddLayer(new BasicLayer(2)); network.AddLayer(new BasicLayer(1)); network.Structure.FinalizeStructure(); network.Reset(); ·       Neural networks frequently start with a random weight matrix. This provides a starting point for the training methods. These random values will be tested and refined into an acceptable solution. However, sometimes the initial random values are too far off. Sometimes it may be necessary to reset the weights again, if training is ineffective. These weights make up the long-term memory of the neural network. Additionally, some layers have threshold values that also contribute to the long-term memory of the neural network. Some neural networks also contain context layers, which give the neural network a short-term memory as well. The neural network learns by modifying these weight and threshold values. ·       Now that the neural network has been created, it must be trained. Training a Neural Network ·       construct a INeuralDataSet object - contains the input array and the expected output array (of corresponding range). Even though there is only one output value, we must still use a two-dimensional array to represent the output. public static double[][] XOR_INPUT ={ new double[2] { 0.0, 0.0 }, new double[2] { 1.0, 0.0 }, new double[2] { 0.0, 1.0 }, new double[2] { 1.0, 1.0 } };   public static double[][] XOR_IDEAL = { new double[1] { 0.0 }, new double[1] { 1.0 }, new double[1] { 1.0 }, new double[1] { 0.0 } };   INeuralDataSet trainingSet = new BasicNeuralDataSet(XOR_INPUT, XOR_IDEAL); ·       Training is the process where the neural network's weights are adjusted to better produce the expected output. Training will continue for many iterations, until the error rate of the network is below an acceptable level. Encog supports many different types of training. Resilient Propagation (RPROP) - general-purpose training algorithm. All training classes implement the ITrain interface. The RPROP algorithm is implemented by the ResilientPropagation class. Training the neural network involves calling the Iteration method on the ITrain class until the error is below a specific value. The code loops through as many iterations, or epochs, as it takes to get the error rate for the neural network to be below 1%. Once the neural network has been trained, it is ready for use. ITrain train = new ResilientPropagation(network, trainingSet);   for (int epoch=0; epoch < 10000; epoch++) { train.Iteration(); Debug.Print("Epoch #" + epoch + " Error:" + train.Error); if (train.Error > 0.01) break; } Executing a Neural Network ·       Call the Compute method on the BasicNetwork class. Console.WriteLine("Neural Network Results:"); foreach (INeuralDataPair pair in trainingSet) { INeuralData output = network.Compute(pair.Input); Console.WriteLine(pair.Input[0] + "," + pair.Input[1] + ", actual=" + output[0] + ",ideal=" + pair.Ideal[0]); } ·       The Compute method accepts an INeuralData class and also returns a INeuralData object. Neural Network Results: 0.0,0.0, actual=0.002782538818034049,ideal=0.0 1.0,0.0, actual=0.9903741937121177,ideal=1.0 0.0,1.0, actual=0.9836807956566187,ideal=1.0 1.0,1.0, actual=0.0011646072586172778,ideal=0.0 ·       the network has not been trained to give the exact results. This is normal. Because the network was trained to 1% error, each of the results will also be within generally 1% of the expected value.

  • Silverlight for Windows Embedded tutorial (step 6)

    - by Valter Minute
    In this tutorial step we will develop a very simple clock application that may be used as a screensaver on our devices and will allow us to discover a new feature of Silverlight for Windows Embedded (transforms) and how to use an “old” feature of Windows CE (timers) inside a Silverlight for Windows Embedded application. Let’s start with some XAML, as usual: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="640" Height="480" FontSize="18" x:Name="Clock">   <Canvas x:Name="LayoutRoot" Background="#FF000000"> <Grid Height="24" Width="150" Canvas.Left="320" Canvas.Top="234" x:Name="SecondsHand" Background="#FFFF0000"> <TextBlock Text="Seconds" TextWrapping="Wrap" Width="50" HorizontalAlignment="Right" VerticalAlignment="Center" x:Name="SecondsText" Foreground="#FFFFFFFF" TextAlignment="Right" Margin="2,2,2,2"/> </Grid> <Grid Height="24" x:Name="MinutesHand" Width="100" Background="#FF00FF00" Canvas.Left="320" Canvas.Top="234"> <TextBlock HorizontalAlignment="Right" x:Name="MinutesText" VerticalAlignment="Center" Width="50" Text="Minutes" TextWrapping="Wrap" Foreground="#FFFFFFFF" TextAlignment="Right" Margin="2,2,2,2"/> </Grid> <Grid Height="24" x:Name="HoursHand" Width="50" Background="#FF0000FF" Canvas.Left="320" Canvas.Top="234"> <TextBlock HorizontalAlignment="Right" x:Name="HoursText" VerticalAlignment="Center" Width="50" Text="Hours" TextWrapping="Wrap" Foreground="#FFFFFFFF" TextAlignment="Right" Margin="2,2,2,2"/> </Grid> </Canvas> </UserControl> This XAML file defines three grid panels, one for each hand of our clock (we are implementing an analog clock using one of the most advanced technologies of the digital world… how cool is that?). Inside each hand we put a TextBlock that will be used to display the current hour, minute, second inside the dial (you can’t do that on plain old analog clocks, but it looks nice). As usual we use XAML2CPP to generate the boring part of our code. We declare a class named “Clock” and derives from the TClock template that XAML2CPP has declared for us. class Clock : public TClock<Clock> { ... }; Our WinMain function is more or less the same we used in all the previous samples. It initializes the XAML runtime, create an instance of our class, initialize it and shows it as a dialog: int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { if (!XamlRuntimeInitialize()) return -1;   HRESULT retcode;   IXRApplicationPtr app; if (FAILED(retcode=GetXRApplicationInstance(&app))) return -1; Clock clock;   if (FAILED(clock.Init(hInstance,app))) return -1;     UINT exitcode;   if (FAILED(clock.GetVisualHost()->StartDialog(&exitcode))) return -1;   return exitcode; } Silverlight for Windows Embedded provides a lot of features to implement our UI, but it does not provide timers. How we can update our clock if we don’t have a timer feature? We just use plain old Windows timers, as we do in “regular” Windows CE applications! To use a timer in WinCE we should declare an id for it: #define IDT_CLOCKUPDATE 0x12341234 We also need an HWND that will be used to receive WM_TIMER messages. Our Silverlight for Windows Embedded page is “hosted” inside a GWES Window and we can retrieve its handle using the GetContainerHWND function of our VisualHost object. Let’s see how this is implemented inside our Clock class’ Init method: HRESULT Init(HINSTANCE hInstance,IXRApplication* app) { HRESULT retcode;   if (FAILED(retcode=TClock<Clock>::Init(hInstance,app))) return retcode;   // create the timer user to update the clock HWND clockhwnd;   if (FAILED(GetVisualHost()->GetContainerHWND(&clockhwnd))) return -1;   timer=SetTimer(clockhwnd,IDT_CLOCKUPDATE,1000,NULL); return 0; } We use SetTimer to create a new timer and GWES will send a WM_TIMER to our window every second, giving us a chance to update our clock. That sounds great… but how could we handle the WM_TIMER message if we didn’t implement a window procedure for our window? We have to move a step back and look how a visual host is created. This code is generated by XAML2CPP and is inside xaml2cppbase.h: virtual HRESULT CreateHost(HINSTANCE hInstance,IXRApplication* app) { HRESULT retcode; XRWindowCreateParams wp;   ZeroMemory(&wp, sizeof(XRWindowCreateParams)); InitWindowParms(&wp);   XRXamlSource xamlsrc;   SetXAMLSource(hInstance,&xamlsrc); if (FAILED(retcode=app->CreateHostFromXaml(&xamlsrc, &wp, &vhost))) return retcode;   if (FAILED(retcode=vhost->GetRootElement(&root))) return retcode; return S_OK; } As you can see the CreateHostFromXaml function of IXRApplication accepts a structure named XRWindowCreateParams that control how the “plain old” GWES Window is created by the runtime. This structure is initialized inside the InitWindowParm method: // Initializes Windows parameters, can be overridden in the user class to change its appearance virtual void InitWindowParms(XRWindowCreateParams* wp) { wp->Style = WS_OVERLAPPED; wp->pTitle = windowtitle; wp->Left = 0; wp->Top = 0; } This method set up the window style, title and position. But the XRWindowCreateParams contains also other fields and, since the function is declared as virtual, we could initialize them inside our version of InitWindowParms: // add hook procedure to the standard windows creation parms virtual void InitWindowParms(XRWindowCreateParams* wp) { TClock<Clock>::InitWindowParms(wp);   wp->pHookProc=StaticHostHookProc; wp->pvUserParam=this; } This method calls the base class implementation (useful to not having to re-write some code, did I told you that I’m quite lazy?) and then initializes the pHookProc and pvUserParam members of the XRWindowsCreateParams structure. Those members will allow us to install a “hook” procedure that will be called each time the GWES window “hosting” our Silverlight for Windows Embedded UI receives a message. We can declare a hook procedure inside our Clock class: // static hook procedure static BOOL CALLBACK StaticHostHookProc(VOID* pv,HWND hwnd,UINT Msg,WPARAM wParam,LPARAM lParam,LRESULT* pRetVal) { ... } You should notice two things here. First that the function is declared as static. This is required because a non-static function has a “hidden” parameters, that is the “this” pointer of our object. Having an extra parameter is not allowed for the type defined for the pHookProc member of the XRWindowsCreateParams struct and so we should implement our hook procedure as static. But in a static procedure we will not have a this pointer. How could we access the data member of our class? Here’s the second thing to notice. We initialized also the pvUserParam of the XRWindowsCreateParams struct. We set it to our this pointer. This value will be passed as the first parameter of the hook procedure. In this way we can retrieve our this pointer and use it to call a non-static version of our hook procedure: // static hook procedure static BOOL CALLBACK StaticHostHookProc(VOID* pv,HWND hwnd,UINT Msg,WPARAM wParam,LPARAM lParam,LRESULT* pRetVal) { return ((Clock*)pv)->HostHookProc(hwnd,Msg,wParam,lParam,pRetVal); } Inside our non-static hook procedure we will have access to our this pointer and we will be able to update our clock: // hook procedure (handles timers) BOOL HostHookProc(HWND hwnd,UINT Msg,WPARAM wParam,LPARAM lParam,LRESULT* pRetVal) { switch (Msg) { case WM_TIMER: if (wParam==IDT_CLOCKUPDATE) UpdateClock(); *pRetVal=0; return TRUE; } return FALSE; } The UpdateClock member function will update the text inside our TextBlocks and rotate the hands to reflect current time: // udates Hands positions and labels HRESULT UpdateClock() { SYSTEMTIME time; HRESULT retcode;   GetLocalTime(&time);   //updates the text fields TCHAR timebuffer[32];   _itow(time.wSecond,timebuffer,10);   SecondsText->SetText(timebuffer);   _itow(time.wMinute,timebuffer,10);   MinutesText->SetText(timebuffer);   _itow(time.wHour,timebuffer,10);   HoursText->SetText(timebuffer);   if (FAILED(retcode=RotateHand(((float)time.wSecond)*6-90,SecondsHand))) return retcode;   if (FAILED(retcode=RotateHand(((float)time.wMinute)*6-90,MinutesHand))) return retcode;   if (FAILED(retcode=RotateHand(((float)(time.wHour%12))*30-90,HoursHand))) return retcode;   return S_OK; } The function retrieves current time, convert hours, minutes and seconds to strings and display those strings inside the three TextBlocks that we put inside our clock hands. Then it rotates the hands to position them at the right angle (angles are in degrees and we have to subtract 90 degrees because 0 degrees means horizontal on Silverlight for Windows Embedded and usually a clock 0 is in the top position of the dial. The code of the RotateHand function uses transforms to rotate our clock hands on the screen: // rotates a Hand HRESULT RotateHand(float angle,IXRFrameworkElement* Hand) { HRESULT retcode; IXRRotateTransformPtr rotatetransform; IXRApplicationPtr app;   if (FAILED(retcode=GetXRApplicationInstance(&app))) return retcode;   if (FAILED(retcode=app->CreateObject(IID_IXRRotateTransform,&rotatetransform))) return retcode;     if (FAILED(retcode=rotatetransform->SetAngle(angle))) return retcode;   if (FAILED(retcode=rotatetransform->SetCenterX(0.0))) return retcode;   float height;   if (FAILED(retcode==Hand->GetActualHeight(&height))) return retcode;   if (FAILED(retcode=rotatetransform->SetCenterY(height/2))) return retcode; if (FAILED(retcode=Hand->SetRenderTransform(rotatetransform))) return retcode;   return S_OK; } It creates a IXRotateTransform object, set its rotation angle and origin (the default origin is at the top-left corner of our Grid panel, we move it in the vertical center to keep the hand rotating around a single point in a more “clock like” way. Then we can apply the transform to our UI object using SetRenderTransform. Every UI element (derived from IXRFrameworkElement) can be rotated! And using different subclasses of IXRTransform also moved, scaled, skewed and distorted in many ways.

  • creating Linq to sqlite dbml from DbLinq source code

    - by Veer
    Hi All, I tried to create linq-to-sqlite dbml using DbLinq but in vain. Each time I get different type of errors. May be I'm somewhere wrong. Can anyone tell me the step by step procedure to create the dbml file from the Dblinq source code. Edit: Steps I Followed: I downloaded the source file from this link. Edited the "run_sqliteMetal.bat" file in \\DbLinq-0.19\src\DbMetal folder as 'DbMetal.exe -database:myDb.db3 -namespace:myNS -code:myCode.cs' -dbml:myDbml.dbml Tried to run the DbMetal project file to produce the executable but there was a runtime error since Options object in Parameters.cs was null. Hence downloaded the readymade exe file from this location Copied it into the \DbLinq-0.19\src\DbMetal folder Executed the "run_sqliteMetal.bat" file I got a blank screen and Windows Error Msg "DbLinq has stopped Working" Any help? Thanks in advance, Veer

  • ASP.NET Web Forms Extensibility: Providers

    - by Ricardo Peres
    Introduction This will be the first of a number of posts on ASP.NET extensibility. At this moment I don’t know exactly how many will be and I only know a couple of subjects that I want to talk about, so more will come in the next days. I have the sensation that the providers offered by ASP.NET are not widely know, although everyone uses, for example, sessions, they may not be aware of the extensibility points that Microsoft included. This post won’t go into details of how to configure and extend each of the providers, but will hopefully give some pointers on that direction. Canonical These are the most widely known and used providers, coming from ASP.NET 1, chances are, you have used them already. Good support for invoking client side, either from a .NET application or from JavaScript. Lots of server-side controls use them, such as the Login control for example. Membership The Membership provider is responsible for managing registered users, including creating new ones, authenticating them, changing passwords, etc. ASP.NET comes with two implementations, one that uses a SQL Server database and another that uses the Active Directory. The base class is Membership and new providers are registered on the membership section on the Web.config file, as well as parameters for specifying minimum password lengths, complexities, maximum age, etc. One reason for creating a custom provider would be, for example, storing membership information in a different database engine. 1: <membership defaultProvider="MyProvider"> 2: <providers> 3: <add name="MyProvider" type="MyClass, MyAssembly"/> 4: </providers> 5: </membership> Role The Role provider assigns roles to authenticated users. The base class is Role and there are three out of the box implementations: XML-based, SQL Server and Windows-based. Also registered on Web.config through the roleManager section, where you can also say if your roles should be cached on a cookie. If you want your roles to come from a different place, implement a custom provider. 1: <roleManager defaultProvider="MyProvider"> 2: <providers> 3: <add name="MyProvider" type="MyClass, MyAssembly" /> 4: </providers> 5: </roleManager> Profile The Profile provider allows defining a set of properties that will be tied and made available to authenticated or even anonymous ones, which must be tracked by using anonymous authentication. The base class is Profile and the only included implementation stores these settings in a SQL Server database. Configured through profile section, where you also specify the properties to make available, a custom provider would allow storing these properties in different locations. 1: <profile defaultProvider="MyProvider"> 2: <providers> 3: <add name="MyProvider" type="MyClass, MyAssembly"/> 4: </providers> 5: </profile> Basic OK, I didn’t know what to call these, so Basic is probably as good as a name as anything else. Not supported client-side (doesn’t even make sense). Session The Session provider allows storing data tied to the current “session”, which is normally created when a user first accesses the site, even when it is not yet authenticated, and remains all the way. The base class and only included implementation is SessionStateStoreProviderBase and it is capable of storing data in one of three locations: In the process memory (default, not suitable for web farms or increased reliability); A SQL Server database (best for reliability and clustering); The ASP.NET State Service, which is a Windows Service that is installed with the .NET Framework (ok for clustering). The configuration is made through the sessionState section. By adding a custom Session provider, you can store the data in different locations – think for example of a distributed cache. 1: <sessionState customProvider=”MyProvider”> 2: <providers> 3: <add name=”MyProvider” type=”MyClass, MyAssembly” /> 4: </providers> 5: </sessionState> Resource A not so known provider, allows you to change the origin of localized resource elements. By default, these come from RESX files and are used whenever you use the Resources expression builder or the GetGlobalResourceObject and GetLocalResourceObject methods, but if you implement a custom provider, you can have these elements come from some place else, such as a database. The base class is ResourceProviderFactory and there’s only one internal implementation which uses these RESX files. Configuration is through the globalization section. 1: <globalization resourceProviderFactoryType="MyClass, MyAssembly" /> Health Monitoring Health Monitoring is also probably not so well known, and actually not a good name for it. First, in order to understand what it does, you have to know that ASP.NET fires “events” at specific times and when specific things happen, such as when logging in, an exception is raised. These are not user interface events and you can create your own and fire them, nothing will happen, but the Health Monitoring provider will detect it. You can configure it to do things when certain conditions are met, such as a number of events being fired in a certain amount of time. You define these rules and route them to a specific provider, which must inherit from WebEventProvider. Out of the box implementations include sending mails, logging to a SQL Server database, writing to the Windows Event Log, Windows Management Instrumentation, the IIS 7 Trace infrastructure or the debugger Trace. Its configuration is achieved by the healthMonitoring section and a reason for implementing a custom provider would be, for example, locking down a web application in the event of a significant number of failed login attempts occurring in a small period of time. 1: <healthMonitoring> 2: <providers> 3: <add name="MyProvider" type="MyClass, MyAssembly"/> 4: </providers> 5: </healthMonitoring> Sitemap The Sitemap provider allows defining the site’s navigation structure and associated required permissions for each node, in a tree-like fashion. Usually this is statically defined, and the included provider allows it, by supplying this structure in a Web.sitemap XML file. The base class is SiteMapProvider and you can extend it in order to supply you own source for the site’s structure, which may even be dynamic. Its configuration must be done through the siteMap section. 1: <siteMap defaultProvider="MyProvider"> 2: <providers><add name="MyProvider" type="MyClass, MyAssembly" /> 3: </providers> 4: </siteMap> Web Part Personalization Web Parts are better known by SharePoint users, but since ASP.NET 2.0 they are included in the core Framework. Web Parts are server-side controls that offer certain possibilities of configuration by clients visiting the page where they are located. The infrastructure handles this configuration per user or globally for all users and this provider is responsible for just that. The base class is PersonalizationProvider and the only included implementation stores settings on SQL Server. Add new providers through the personalization section. 1: <webParts> 2: <personalization defaultProvider="MyProvider"> 3: <providers> 4: <add name="MyProvider" type="MyClass, MyAssembly"/> 5: </providers> 6: </personalization> 7: </webParts> Build The Build provider is responsible for compiling whatever files are present on your web folder. There’s a base class, BuildProvider, and, as can be expected, internal implementations for building pages (ASPX), master pages (Master), user web controls (ASCX), handlers (ASHX), themes (Skin), XML Schemas (XSD), web services (ASMX, SVC), resources (RESX), browser capabilities files (Browser) and so on. You would write a build provider if you wanted to generate code from any kind of non-code file so that you have strong typing at development time. Configuration goes on the buildProviders section and it is per extension. 1: <buildProviders> 2: <add extension=".ext" type="MyClass, MyAssembly” /> 3: </buildProviders> New in ASP.NET 4 Not exactly new since they exist since 2010, but in ASP.NET terms, still new. Output Cache The Output Cache for ASPX pages and ASCX user controls is now extensible, through the Output Cache provider, which means you can implement a custom mechanism for storing and retrieving cached data, for example, in a distributed fashion. The base class is OutputCacheProvider and the only implementation is private. Configuration goes on the outputCache section and on each page and web user control you can choose the provider you want to use. 1: <caching> 2: <outputCache defaultProvider="MyProvider"> 3: <providers> 4: <add name="MyProvider" type="MyClass, MyAssembly"/> 5: </providers> 6: </outputCache> 7: </caching> Request Validation A big change introduced in ASP.NET 4 (and refined in 4.5, by the way) is the introduction of extensible request validation, by means of a Request Validation provider. This means we are not limited to either enabling or disabling event validation for all pages or for a specific page, but we now have fine control over each of the elements of the request, including cookies, headers, query string and form values. The base provider class is RequestValidator and the configuration goes on the httpRuntime section. 1: <httpRuntime requestValidationType="MyClass, MyAssembly" /> Browser Capabilities The Browser Capabilities provider is new in ASP.NET 4, although the concept exists from ASP.NET 2. The idea is to map a browser brand and version to its supported capabilities, such as JavaScript version, Flash support, ActiveX support, and so on. Previously, this was all hardcoded in .Browser files located in %WINDIR%\Microsoft.NET\Framework(64)\vXXXXX\Config\Browsers, but now you can have a class inherit from HttpCapabilitiesProvider and implement your own mechanism. Register in on the browserCaps section. 1: <browserCaps provider="MyClass, MyAssembly" /> Encoder The Encoder provider is responsible for encoding every string that is sent to the browser on a page or header. This includes for example converting special characters for their standard codes and is implemented by the base class HttpEncoder. Another implementation takes care of Anti Cross Site Scripting (XSS) attacks. Build your own by inheriting from one of these classes if you want to add some additional processing to these strings. The configuration will go on the httpRuntime section. 1: <httpRuntime encoderType="MyClass, MyAssembly" /> Conclusion That’s about it for ASP.NET providers. It was by no means a thorough description, but I hope I managed to raise your interest on this subject. There are lots of pointers on the Internet, so I only included direct references to the Framework classes and configuration sections. Stay tuned for more extensibility!

  • BizTalk server problem

    - by WtFudgE
    Hi, we have a biztalk server (a virtual one (1!)...) at our company, and an sql server where the data is being kept. Now we have a lot of data traffic. I'm talking about hundred of thousands. So I'm actually not even sure if one server is pretty safe, but our company is not that easy to convince. Now recently we have a lot of problems. Allow me to situate in detail, so I'm not missing anything: Our server has 5 applications: One with 3 orchestrations, 12 send ports, 16 receive locations. One with 4 orchestrations, 32 send ports, 20 receive locations. One with 4 orchestrations, 24 send ports, 20 receive locations. One with 47 (yes 47) orchestrations, 37 send ports, 6 receive locations. One with common application with a couple of resources. Our problems have occured since we deployed the applications with the 47 orchestrations. A lot of these orchestrations use assign shapes which use c# code to do the mapping. This is because we use HL7 extensions and this is kind of special, so by using c# code & xpath it was a lot easier to do the mapping because a lot of these schema's look alike. The c# reads in XmlNodes received through xpath, and returns XmlNode which are then assigned again to biztalk messages. I'm not sure if this could be the cause, but I thought I'd mention it. The send and receive ports have a lot of different types: File, MQSeries, SQL, MLLP, FTP. Each of these types have a different host instances, to balance out the load. Our orchestrations use the BiztalkApplication host. On this server also a couple of scripts are running, mostly ftp upload scripts & also a zipper script, which zips files every half an hour in a daily zip and deletes the zip files after a month. We use this zipscript on our backup files (we backup a lot, backups are also on our server), we did this because the server had problems with sending files to a location where there were a lot (A LOT) of files, so after the files were reduced to zips it went better. Now the problems we are having recently are mainly two major problems: Our most important problem is the following. We kept a receive location with a lot of messages on a queue for testing. After we start this receive location which uses the 47 orchestrations, the running service instances start to sky rock. Ok, this is pretty normal. Let's say about 10000, and then we stop the receive location to see how biztalk handles these 10000 instances. Normally they would go down pretty fast, and it does sometimes, but after a while it starts to "throttle", meaning they just stop being processed and the service instances stay at the same number, for example in 30 seconds it goes down from 10000 to 4000 and then it stays at 4000 and it lowers very very very slowly, like 30 in 5minutes or something. So this means, that all the other service instances of the other applications are also stuck in here, and they are also not processed. We noticed that after restarting our host instances the instance number went down fast again. So we tried to selectively restart different host instances to locate the problem. We noticed that eventually restarting the file send/receive host instance would do the trick. So we thought file sends would be the problem. Concidering that we make a lot of backups. So we replaced the file type backups with mqseries backups. The same problem occured, and funny thing, restarting the file send/receive host still fixes the problem. No errors can be found in the event viewer either. A second problem we're having is. That sometimes at arround 6 am, all or a part of the host instances are being stopped. In the event viewer we noticed the following errors (these are more than one): The receive location "MdnBericht SQL" with URL "SQL://ZNACDBPEG/mdnd0001/" is shutting down. Details:"The error threshold has been exceeded. The receive location is shutting down.". The Messaging Engine failed to add a receive location "M2m Othello Export Start Bestand" with URL "\m2mservices\Othello_import$\DataFilter Start*.xml" to the adapter "FILE". Reason: "The FILE adapter cannot access the folder \m2mservices\Othello_import$\DataFilter Start. Verify this folder exists. Error: Logon failure: unknown user name or bad password. ". The FILE adapter cannot access the folder \m2mservices\Othello_import$\DataFilter Start. Verify this folder exists. Error: Logon failure: unknown user name or bad password. An attempt to connect to "BizTalkMsgBoxDb" SQL Server database on server "ZNACDBBTS" failed. Error: "Login failed for user ''. The user is not associated with a trusted SQL Server connection." It woould seem that there's a login failure at this time and that because of it other services are also experiencing problems, and eventually they are shut down. The thing is, our user is admin, and it's impossible that it's password is wrong "sometimes". We have concidering that the problem could be due to an infrastructure problem, but that's not really are department. I know it's a long post, but we're not sure anymore what to do. Would adding another server and balancing the load solve our problems? Is there a way to meassure our balance and know where to start splitting? What are normal numbers of load etc? I appreciate any answers because these issues are getting worse and we're also on a deadline. Thanks a lot for replies!

  • JMeter to grab full querystring into a variable for future use

    - by jfbauer
    Someone provided me the regex to parse out a query string: (?<=\?)[^?]+$ I am trying to use that in JMeter with no luck (although I am successful in pulling out individual query string parameter values based on various example postings on the web). I created a regular expression extractor called "Grab QueryString". I selected the URL response field to check. For the reference name, I typed "myQueryString". For the regular expression, I entered your text. For template, I entered $1$ Match no = 1 Default Value = ERROR Unfortunately, "myQueryString" is getting populated with ERROR and not the URL query string as hoped when I try and use it as a parameter in a future GET. Thus, I see this in the "View Results Tree": https:/www.website.com/folder/page.aspx?ERROR Instead of: https:/www.website.com/folder/page.aspx?jfhjHSDjgdjhsjhsdhjSJHWed Did I do something wrong? Anyone have any suggestions?

  • How can I get TFS 2010 to build each project to a separate directory?

    In our project, we'd like to have our TFS build put each project into its own folder under the drop folder, instead of dropping all of the files into one flat structure. To illustrate, we'd like to see something like this: DropFolder/ Foo/ foo.exe Bar/ bar.dll Baz baz.dll This is basically the same question as was asked here, but now that we're using workflow-based builds, those solutions don't seem to work. The solution using the CustomizableOutDir property looked like it would work best for us, but I can't get that property to be recognized. I customized our workflow to pass it in to MSBuild as a command line argument (/p:CustomizableOutDir=true), but it seems MSBuild just ignores it and puts the output into the OutDir given by the workflow. I looked at the build logs, and I can see that the CustomizableOutDir and OutDir properties are both getting set in the command line args to MSBuild. I still need OutDir to be passed in so that I can copy my files to TeamBuildOutDir at the end. Any idea why my CustomizableOutDir parameter isn't getting recognized, or if there's a better way to achieve this?

  • Outlook 2003 View Control with C#

    - by Eleasar
    I want to embed a custom c# windows form (or WPF) user control into an outlook view. I am using Outlook 2003 and Visual Studio 2008. I did download an example for Outlook 2007 here: http://blogs.msdn.com/e2eblog/archive/2008/01/09/outlook-folder-homepage-hosting-wpf-activex-and-windows-forms-controls.aspx and also here: http://msdn.microsoft.com/en-us/library/aa479345.aspx I tested it and under 2007 it is working, but for 2003 i am getting the following error when i want to open the view: Could not complete the operation due to error 80131509 I can start it from Visual Studio, it is registering the folder just fine, debugging works and all that. It creates an HTML page that contains my type as an object parameter - but the Initialize method that should be called is either not present (not shown via JS) or it has some errors. The breakpoints for RegisterSafeForScripting are also never hit - maybe related to that. Thx in advance!

  • python metaprogramming

    - by valya
    I'm trying to archive a task which turns out to be a bit complicated since I'm not very good at Python metaprogramming. I want to have a module locations with function get_location(name), which returns a class defined in a folder locations/ in the file with the name passed to function. Name of a class is something like NameLocation. So, my folder structure: program.py locations/ __init__.py first.py second.py program.py will be smth with with: from locations import get_location location = get_location('first') and the location is a class defined in first.py smth like this: from locations import Location # base class for all locations, defined in __init__ (?) class FirstLocation(Location): pass etc. Okay, I've tried a lot of import and getattribute statements but now I'm bored and surrender. How to archive such behaviour?

  • faking a filesystem / virtual filesystem

    - by attwad
    I have a web service to which users upload python scripts that are run on a server. Those scripts process files that are on the server and I want them to be able to see only a certain hierarchy of the server's filesystem (best: a temporary folder on which I copy the files I want processed and the scripts). The server will ultimately be a linux based one but if a solution is also possible on Windows it would be nice to know how. What I though of is creating a user with restricted access to folders of the FS - ultimately only the folder containing the scripts and files - and launch the python interpreter using this user. Can someone give me a better alternative? as relying only on this makes me feel insecure, I would like a real sandboxing or virtual FS feature where I could run safely untrusted code.

  • ASP.Net Application Trust Medium File IO Outside Virtual Directory

    - by Trey Gramann
    I am trying to determine how suicidal this is... I have a hosting environment where a custom ASP.Net CMS application needs to access the files in the root folder of a website even though it is in a virtual folder so it can be shared accross many sites. I can modify the Medium trust on the server and came up with this... <IPermission class="FileIOPermission" version="1" Read="$AppDir$;$AppDir$\.." Write="$AppDir$;$AppDir$\.." Append="$AppDir$;$AppDir$\.." PathDiscovery="$AppDir$;$AppDir$\.."/> Oddly enough, it works. Yes, I understand it is doing this for all the Apps. I am a bit at a loss as to easy ways to test what else is being exposed. Feels dangerous. Opinions?

  • Rewrite rules for subfolders

    - by pg
    This may seem like a silly question but I can't figure it out. let's say I have a public_html folder with various folders like: Albatross, Blackbirds, Crows and Faqs. I want to make it so that any traffic to Albatross/faqs.php, Blackbirds/faqs.php, Crows/faqs.php etc will see the file that is at faqs/faqs.php?bird=albatross or faqs/faqs.php?bird=crows or what have you. If I go into the Albatross folder's .htaccess file I can do this RewriteRule faqs.php$ /faqs/faqs.php?cat=albatross[QSA] Which works fine, but I want to put something in the top level .htacces that works for all of them, so tried: RewriteRule faqs.php$ /faqs/faqs.php?cat=albatross[QSA] RewriteRule /(.*)/faqs.php$ /faqs/faqs.php?cat=$1 [QSA] and even RewriteRule /albatross/faqs.php$ /faqs/faqs.php?cat=albatross [QSA] and various others but nothing seems to work, when I go to http://www.birdsandwhatnot.com/albatross/faqs.php I see the same file the same way it's always been. Does the presence of an .htaccess file in the subfolder conflict with the higher up .htaccess file? Am I missing something?

  • Windows Explorer argument not being interpreted?

    - by MarceloRamires
    I'm currently using: Process.Start("explorer.exe", "/Select, " + fullPath); //with file name.extension That basically tells windows explorer to open the folder where the file is in, with the given file selected. But, by the forces of evil, sometimes it works and sometimes it just opens the file ("/select" is... ignored) Has anyone ever experienced this? If it changes anything, it's a file in a local network and the path looks like this \\server\folder\subfolder\something\file.ext (of course in c# every '\' is doubled, and @ is not a choice, the path is generated by something else) I'll be constantly reading comments to supply any aditional information

  • nmake makefile, linking objects files in a subfolder

    - by Gauthier
    My makefile defines a link command: prod_link = $(LINK) $(LINK_FLAGS) -o$(PROD_OUT) $(PROD_OBJS) where $(PROD_OBJS) is a list of object files of the form: PROD_OBJS = objfile1.obj objfile2.obj objfile3.obj ... objfileN.obj Now the makefile itself is at the root of my project directory. It gets messy to have object and listing files at the root, I'd like to put them in a subfolder. Building and outputing the obj files to a subfolder works, I'm doing it with suffixes and inference: .s.obj: $(ASSEMBLY) $(FLAGS) $*.s -o Objects\$*.obj The problem is to pass the Objects folder to the link command. I tried: prod_link = $(LINK) $(LINK_FLAGS) -o$(PROD_OUT) Objects\$(PROD_OBJS) but only the first file in the list of object files gets the folder's name. How can I pass the Objects subfolder to all files of my list $(PROD_OBJS)? EDIT I tried also PROD_OBJS = $(patsubst %.ss,Object\%.obj, $(PROD_SRC)) but got: makefile(51) : fatal error U1000: syntax error : ')' missing in macro invocation Stop. This is quite strange...
