• Can't see or add Website Data Sources in RDLC report in ASP.NET MVC

  - by RobertC

  In the RDLC report, in Design view in Visual Studio 2008, we don't see anything in the Website Data Sources tab and the button to Add New Data Source is grayed out. Only the Refresh button is enabled, and clicking it doesn't do anything. Our business logic layer returns Lists of business objects and the business logic and business object projects are both referenced by the MVC project. This is an MVC app, so there is no App_Code folder. How do we get our business objects to appear in the Website Data Sources list so we can drag and drop fields from the object onto our RDLC report?

• WPF MVVM Property Change Animation

  - by cjibo

  I am looking for a clean way to start an animation that will have dynamic values. Basically I want to do an animation where an element changes width based on the data of another element. Say I have a TextBlock that's Text Property is Binding. When this property changes I want a visual element say a Rectangle for our sake to do a DoubleAnimation changing the width from previous value to the new value. I am trying to stay away from putting code in my view if possible. I've looked into DataTriggers but they seem to require that you know what the value would be such as an Enum. In my case it is just the value changing that needs to trigger a storyboard and the animation would need to start at the current(previous) value and move nicely to the new value. Any ideas. Maybe I just missed a property.

• Converting MS Word Documents to PDF in ASP.NET

  - by glaxaco

  Similar questions have been asked, but nothing exactly like mine, so here goes. We have a collection of Microsoft Word documents on an ASP.NET web server with merge fields whose values are filled in as a result of user form submissions. After the field merge, the server must convert the document to PDF and stream it down to the browser. Our first inclination was to use the Visual Studio Tools for Office API; however, we ran into this warning from Microsoft: Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment. It looks like the field manipulation can be done using the Open XML SDK, but what's the best way to convert Word 2007 documents to PDF without opening Word? The optimal solution would be low-cost, scalable, have a low memory footprint, be easy to deploy, and have a .NET API.

• WPF: Turning off animations, data binding temporarly for invisible objects?;)

  - by TomTom

  I have a window that contains a tab control - basically multiple sheets with visualizations on them. The visualtizations are: possible very resource intensive during rendering relying on constant data updates to update their underlying models Obviously only one sheet can be visible every time ;) Anyone knows of a good way to turn off all visualization, animations, data binding for a control / panel and it's contained controls? If I would find a way to do that, I could simply turn off all the invisible sheets and reactivate them as needed. The models must be kept running - some of the visual stuff is pretty complex and really relies on constant data updates, and recalculating it when someone switches tabs would be too hard.

• basic question with a dtd

  - by voodoomsr

  i need an element with the characteristics <!ELEMENT section ((comment*)|definition|(comment*))> but that is ambiguous, i get the next message in visual studio Multiple definition of element 'comment' causes the content model to become ambiguous. A content model must be formed such that during validation of an element information item sequence, the particle contained directly, indirectly or implicitly therein with which to attempt to validate each item in the sequence in turn can be uniquely determined without examining the content or attributes of that item, and without any information about the items in the remainder of the sequence. So how can i write correctly that? the correct structure is one definition surrounded by possibles comments elements.

• Grabbing values from Expression.Blend.SampleData

  - by Mitchell Skurnik

  I am trying to figure out how to grab a value from Expression.Blend.SampleData. If my id is equal to a drop down for example, I can grab it by doing this: ((Expression.Blend.SampleData.MyDatabase.something)(MyDropDown.SelectedItem)).description; I need some way to place my own value where (MyDropDown.SelectedItem) is. Visual studio wants me to convert it a "Expression.Blend.SampleData.MyDatabase.something" format. I have tried a few ways to do this but I have been unsuccessful. Any Ideas? EDIT I am starting to think there is no way in Silverlight to do this

• Socket programming and telnet with VB.net

  - by Mike

  I'm writing a GUI-based app in VB.net that talks to a LambdaMOO server via telnet, sends commands to display the object hierarchy, then parses the output and creates a visual representation of the object hierarchy. So my question is: is there some kind of "telnet client" class for .NET to simplify the sending and receiving of data, or do I have to write my own using the socket API? Does Mono have something like this? Barring an easy solution, does anyone have a good tutorial they can point to for telnet client programming in VB.net?

• Memory address of a variable

  - by dotnetvoyager

  Hi Everyone, Is it possible to get the memory address of a variable in C#. What I am trying to do is very simple. I want to declare variables of type Double, Float, Decimal and assign the value 1.1 to each of these variables. Then I would like to go and see how these values are represented in memory. I need to get the memory address of the variable in order to see how its stored in memory. Once I have the memory address I plan to put a break point in the code and use the Debug - Windows - Memory option in visual studio to see how the numbers are stored in memory. Cheers,

• How do I decrease first load time in ASP.net MVC 2?

  - by Bill

  I have an ASP.net MVC 2 application that runs well locally. However when I move the files to my production server, I get a first time lag of about 30 seconds, I assume this is a first compile. After that the application works fine. Then after about 20-30 minutes of non use, the applications takes another 30 seconds or so to load. I did try to precompile the code, but there is still a lag during the first load. Are there any trick to getting the application to work faster on the first load? I am using ASP.net 3.5, IIS 6 , visual studio 2010, MVC 2. Thanks

• Can't get up with RIA demo: part 2

  - by Budda

  Here is a topic: http://stackoverflow.com/questions/2507734/cant-get-up-with-ria-demo where I've described problem with getting access to DomainContext object on the client. That time problem was resolved himself (without any actions from my side, with Visual Studio restart). At the moment, I had the same problem on another PC (Vista x64, VS2008, Silverlight 3.0, RIA Services Toolkit): ThomasDomainContext class that inherits DomainContext was not visible from the page's codebehind file. Again, it was resolved after VS restart and after that I got another problem: Error 1 'VfmElita.Web.ClientBin.ThomasDomainContext' does not contain a definition for 'employee' and no extension method 'employee' accepting a first argument of type 'VfmElita.Web.ClientBin.ThomasDomainContext' could be found (are you missing a using directive or an assembly reference?) D:\Project\Budda\VFMElita\VfmElitaSilverlightClient\MainPage.xaml.cs for the following lines of code (error is noticed for the 31st line): 30: var context = new ThomasDomainContext(); 31: grid1.ItemsSource = context.employee; 32: context.Load(context.GetEmployeeQuery()); Any help is welcome. P.S. Please note, that source code create on the 1st machine is successfully compilable and launchable

• How can I make a Yes/No combobox return true/false?

  - by Kasper Hansen

  I am new to creating forms in Visual Studio and C#. But I made a UI that has some comboboxes where the DropDownStyle is DropDownList. The items shown is Yes and No. But I need to assign this as a boolean value to a property on some object ai and currently do this: if (cmbExample.Text == "Yes") { ai.isPacketType = true; } else if (cmbExample.Text == "No") { ai.isPacketType = false; } I basically want to do something like this (or some other one liner): ai.isPacketType = cmbExample.Text; How do I link the Text Yes to the value true and No to false?

• Invalid Token when using XPath

  - by Andy5

  Hi I am making a modification to a web application using XPath, and when executed I get an error message - Invalid token! This is basic what I am doing public xmlNode GetSelection (SelectParams params, xmldocument docment) { xpathstring = string.format("Name =\'{0}' Displaytag = \'{1}' Manadatory=\'{2}', params.Name, params.Displaytag, params.Manadatory); return document.selectsinglenode(xpathstring); } As you can see, I am making a string and setting values on the nodes I am trying to find against my xml document, and thus returning xml data that matches my parameters. What is happening is that I am getting an xpathexeception error in Visual Studio and it says invalid token. I do know that in the xml document that the parameters I am looking in the tags have double quotes, for example, Name="ABC". So, I thought the problem could be solved using an "\". Can anyone help? Update from comments In the Xml Document, the tag has attributes where they are set as Name="ABC" Displaytag="ATag" Manadatory="true".

• Is there an IDE that provides code completion for Python

  - by Justin Walgran

  I am quite fond of the Intellisense code completion baked into Microsoft Visual Studio. I find that I only type 2 to 4 characters of any given keyword which drasticaly speeds up my coding. Now that I have been spending time writing some Python code I find myself reaching for ctrl+space. Are there any IDEs that support code completion in Python? I do my python development on a Mac so an OS x tool would be preferable. It seems like the doc string property of Python methods is a perfect match for inline API discovery.

• Use relative Path in Microsoft Surface application?

  - by Roflcoptr

  I convert my wave file into a mp3 file by the following code: internal bool convertToMp3() { string lameEXE = @"C:\Users\Roflcoptr\Documents\Visual Studio 2008\Projects\Prototype_Concept_2\Prototype_Concept_2\lame\lame.exe"; string lameArgs = "-V2"; string wavFile = fileName; string mp3File = fileName.Replace("wav", "mp3"); Process process = new Process(); process.StartInfo = new ProcessStartInfo(); process.StartInfo.FileName = lameEXE; process.StartInfo.Arguments = string.Format("{0} {1} {2}", lameArgs, wavFile, mp3File); process.Start(); process.WaitForExit(); int exitCode = process.ExitCode; if (exitCode == 0) { return true; } else { return false; } } This works, but now I'd like to not use the absolut path to the lame.exe but a relative path. I included a lame.exe in the folder /lame/ on the root of the project. How can I reference it?

• Which UML tool can really round-trip java code?

  - by Geir Ove

  Hello, Many UML tools claim to do forward / reverse engineering of Java code. However, it turns out from prior experience, that few tools really work in this area. I haven't been doing Java projects for 3 years, and want to get up to date with the current status in this area. In Particular I am interested in Creating State Machine Skeletons from Diagram, be able to create hooks to my own code, and be able to reverse engineer the State Diagram back (Do not want to change the State Machine itself outside the Tool). Which UML tools works in this area? Enterprise Architecht? Visual Paradigm? Others? Geir Ove Norway

• .net app won't run. When compiling on dest machine (same sources) it does work. Why?

  - by reinier

  I have a service which needs to be deployed on a clients machine. The destination machine is 64bit. My dev machine is also 64 bit. The app is really simple, listens on a port and does some db things. It targets .net 3.5 When I deploy the Anycpu, the X64 or the X86 version, the thing won't install on the clients machine. I checked dependencywalker and it lists: devmgr.dll ieshims.dll wer.dll anyhow...I install visual studio 2008 on the clients machine... check out all the sources. I don't change a thing and compile. Copy the exe over to it's dest locations...and what do you know..it works. Dependencywalker still lists the same dependency problems. How can it be that the act of compiling it on this machine gives me a different exe?

• How to model my database when using entity framework 4?

  - by Junior Ewing

  Trying to wrap my head around the best approach in modelling a database when we are using Entity Framework 4 as the ORM layer. We are going to use asp.net mvc 2 for the application. Is it worth trying to model using the class diagram modeller that comes with Visual Studio 2010 where you graphically configure your models into the EDMX file and then generate out the database structure? I have run into a bunch of non trivial issues and for complex many to many mappings or multi primary key entities the answer is not that obvious even after poking around a while with the tools. I figure its easy at this point to give up and start modelling the DB using real, working DB modelling tools and then try to generate out the EDMX from the database, rather than trying to do the model first approach.

• wxHaskell on OS X

  - by Bill

  I want to use wxHaskell on OS X (Snow Leopard, MacBook Pro). I was able to install the library successfully and the script below: module Main where import Graphics.UI.WX main :: IO () main = start hello hello :: IO () hello = do f <- frame [text := "Hello!"] quit <- button f [text := "Quit", on command := close f] set f [layout := widget quit] does result in a window being displayed with a single button, as specified. However, nothing happens when I click the button - I don't even get the visual response of the button turning blue to indicate that it's been depressed (haha, no pun intended). I've heard that you have to run a package called "macosx-app" on wxHaskell binaries to get them to run, but I can't find this anywhere. It's not on my machine or (as far as I can tell) in the WX or wxHaskell distros. Anyone know what I need to do to get this to work?

• Why does an EXE file that does *nothing* contain so many dummy zero bytes?

  - by Lambert

  Hi, I've compiled a C file that does absolutely nothing (just a main that returns... not even a "Hello, world" gets printed), and I've compiled it with various compilers (MinGW GCC, Visual C++, Windows DDK, etc.). All of them link with the C runtime, which is standard. But what I don't get is: When I open up the file in a hex editor (or a disassembler), why do I see that almost half of the 16 KB is just huge sections of either 0x00 bytes or 0xCC bytes? It seems rather ridiculous to me... is there any way to prevent these from occurring? And why are they there in the first place? Thank you!

• C++ - Opening a file inside a function using fopen. (Noob problem)

  - by Josh

  I am using Visual Studio 2005 (C++). I am passing a string into a function as a char array. I want to open the file passed in as a parameter and use it. I know my code works to an extent, because if I hardcode the filename as the first parameter it works perfectly. I do notice if I look at the value as a watch, the value includes the address aside the string literal. I have tried passing in the filename as a pointer, but it then complains about type conversion with __w64. As I said before it works fine with "filename.txt" in place of fileName. I am stumped. void read(char fileName[50],int destArray[MAX_R][MAX_C],int demSize[2]) { int rows=0; int cols=0; int row=0; int col=0; FILE * f = fopen(fileName,"r"); ...

• Making a rectangular selection in a RichTextBox with Alt-Left-Mouse sweep?

  - by Harold Bamford

  There are quite a few applications that allow you to select a box or rectangle of text by sweeping with mouse while the Alt key is pressed. Visual Studio 2010 does this in the code editor, for instance. Emacs does it. Winword does it. We've all seen it. It seems like there must be a standard pattern to follow to encode this behavior but I cannot seem to find it. I suspect I am not Googling with the correct keywords as all I am getting are false hits on rectangle, Alt-Left, sweep, selection, etc. I'm sure I can code it up but it would mean disabling the normal selection code used in, say, RichTextBox. And that sounds ugly, error prone and probably more work than it is worth. Anybody have a suggestion (be nice! :-) ) of how to do this or an example of how it is done?
