  • Windows Forms Event Log

    - by blu
    I am writing to the event log from my Windows Forms application running on Windows 7 and am getting this message in the event log: The description for Event ID X from source Application cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: Exception Details the message resource is present but the message is not found in the string/message table My logging code is: public void Log(Exception exc) { EventLog.WriteEntry( "Application", exc.ToString(), EventLogEntryType.Error, 100); } My logging on Windows Forms is usually to a DB, but in this case decided to use the event log. I usually use the event log in ASP.NET applications, but those are on XP Pro locally and Windows Server 2003 on the web boxes. Is this a Windows 7 thing or a Windows Forms thing, and what should I do to fix this? Thanks.

  • Seeking reporting or templating tool to generate large formatted PDF reports from dataset

    - by Mr. Tacos
    Say I have some data in MySQL or a big ole CSV file. I also have a report. It's a PDF, call it 100 pages long. I need to generate variations on this PDF for slices of the data. More specific example: I have a CSV file with each StackOverflow user in a row and each column contains various statistics about that user. I have a report called "Your StackOverflow Performance". Its got lots of text, always the same, but each section contains something like: "You Vs. The Average StackOverflow Poster on this metric". I want a table that appears there that has the average data, which is the same in every run of the PDF, in one column. In the second column, I want your data, which is different for each PDF/row in the CSV file/user of StackOverflow. I'm pretty sure people use things like Crystal for this? Is there something in MS SQL Server that's good for this? An open source template language? I'm not even really sure if what I need is called a 'reporting' tool (since I don't really need to do any crunching, the data in this case is being crunched by a series of scripts and SPSS, I don't need bands and subbands and so on) or 'templating'. Is there even such a thing as templating PDFs? Natch, I'd be fine with something that generates output easily scriptable to PDF, like eps, but not something like HTML. The report formatting is fussy and done and externally determined and handed down from on high. It's print-oriented, not webby. Thanks in advance.

  • Kohana 3 jQuery/AJAX request not working

    - by dscher
    I am trying to post some data to a controller in Kohana 3 using the jQuery AJAX method. I seem to have an issue with the data not getting to where I want it to be. I want the data to go to the /application/classes/controller/stock.php file where the file will process the data. I can't seem to figure this one out. Hopefully someone can help. My jQuery ajax call is: $.ajax({ type: 'POST', url: 'add_stock', data: { 'links': 'link_array' } }); 'add_stock' is the name of the action within the controller. I didn't know what else to try. I've also tried '.' and './' hoping that would be right but it's not. In Firebug, although it says the request was 200 OK, I see that the "RESPONSE" is "Failed to load source for: http://localhost/ddm/v2/stocks/add_stock" and my script in my controller which grabs the data isn't working. Here is that code in case it helps: $links = $_POST['links']; $link_obj = Jelly::factory('link') ->set('stock', $stock->id) ->set('links', $links); $link_obj->save(); I think that the problem is that I'm giving the ajax call the ROUTE and not the actual page it needs to deliver the POST data to. I just can't figure it out here. Any help?

  • Autocomplet extender control in ajax (asp.net)?

  • controlling which project header file Xcode will include

    - by jdmuys
    My Xcode project builds to variations of the same product using two targets. The difference between the two is only on which version of an included library is used. For the .c source files it's easy to assign the correct version to the correct target using the target check box. However, including the header file always includes the same one. This is correct for one target, but wrong for the other one. Is there a way to control which header file is included by each target? Here is my project file hierarchy (which is replicated in Xcode): MyProject TheirOldLib theirLib.h theirLib.cpp TheirNewLib theirLib.h theirLib.cpp myCode.cpp and myCode.cpp does thing such as: #include "theirLib.h" … somecode() { #if OLDVERSION theirOldLibCall(…); #else theirNewLibCall(…); #endif } And of course, I define OLDVERSION for one target and not for the other. So is there a way to tell Xcode which theirLib.h to include per target? Constraints: - the two header files have the same name. As a last resort, I could rename one of them, but I'd rather avoid that as this will lead to major hair pulling on the other platforms. - I'm free to tweak my project as I otherwise see fit Thanks for any help.

  • Visual Studio 2005 - OleDbConnection throws "Invalid authorization specification" in Form Designer,

    - by Jason Dagit
    I have a form with an OleDbConnection object on it. This form fails to load in the Form Designer with the message: One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes. Invalid authorization specification at ADODB.ConnectionClass.Open(String ConnectionString, String UserID, String Password, Int32 Options) ... (stack trace continues into user code) I've tracked this down to the OleDbConnection string. If I hardcode in the server IP, username/password/dbinstance into the constructor of the GUI form then the form will load in the designer. At run-time it is not an issue because we require the user to provide the login details. The question: Is it possible to use the OleDbConnection and the Form designer without supplying the database credentials in the source code of the form? For example, is there a property of the OleDbConnection or Form that I can set so that it doesn't need to access the database during Form design? My concern is that if we ever move the database server or change the login that the code will stop working in the designer.

  • How to use a viewstate'd object as a datasource for controls on a user control

    - by user557325
    I've got a listview on a control. Each row comprises a checkbox and another listview. The outer listview is bound to a property on the control (via a method call, can't set a property as a SelectMethod on an ObjectDataSource it would appear) which is lazy loaded suchly: Public ReadOnly Property ProductLineChargeDetails() As List(Of WebServiceProductLineChargeDetail) Get If ViewState("WSProductLineChargeDetails") Is Nothing Then ViewState("WSProductLineChargeDetails") = GetWebServiceProductLineChargeDetails() End If Return DirectCast(ViewState("WSProductLineChargeDetails"), Global.System.Collections.Generic.List(Of Global.MI.Open.WebServiceProductLineChargeDetail)) End Get End Property The shape of the object referenced by the data source is something like this: (psuedocode) Product { bool Licenced; List<Charge> charges; } Charge { int property1; string property2; bool property3 . . . } The reason for the use of viewstate is this: When an one of the checkboxes on one of the outer list view rows is checked or unchecked I want to modify the object that the ODS represents (for example I'll add a couple of Charge objects to the relevant Product object) and then rebind. The problem I'm getting is that after every postback (specifically after checking or unchecking one of the rows' checkbox) my viewstate is empty. Thiss means that any changes I make to my viewstate'd object is lost. Now, I've worked out (after much googling and reading, amongst many others, Scott Mitchel's excellent bit on ViewState) that during initial databinding IsTrackingViewState is set to false. That means, I think, that assigning the return from GetWebServiceProductLineChargeDetails() to the ViewState item in my Property Get during the initial databind won't work. Mind you, even when the IsTrackingViewState is true and I call the Property Get, come the next postback, the viewstate is empty. So do you chaps have any ideas on how I keep the object referenced by the ObjectDataSource in ViewState between postbacks and update it and get those changes to stay in ViewState? This has been going on for a couple of days now and I'm getting fed up! Cheers in advance Steve

  • jquery ui 1.7 autocomplete show dialog on select

    - by Daniel S
    Hello, I am using an autocomplete widget, and would like a dialog to show when an item is selected. The dialog does show up, but I want a field in the dialog to receive focus when it opens. Here is what I have tried so far: //HTML <form action="#"> <p><input id="busca" /></p> </form> <div id="agregar" title="Agregar Parte"> <label for="cantidad">Cantidad:</label> <input name="cantidad" id="cantidad" size="3" /> </div> //jquery $(function(){ $("#agregar").dialog({ autoOpen: false, //also tried open: function(){$("#cantidad").focus()} } ); //.bind("dialogfocus", ... ) does not work either $("#agregar").bind("focus", function(){ $("#cantidad").focus(); }); $("#busca").autocomplete({ source: "/carrito/autocomplete/", minLength: 1, select: function(e, ui) { $("#agregar").dialog("open"); } }); }); I think autoselect's default behavior is still doing something as the autoselect widget receives focus after the dialog is shown. Any help would be greatly appreciated.

  • Info on type family instances

    - by yairchu
    Intro: While checking out snoyman's "persistent" library I found myself wanting ghci's (or another tool) assistance in figuring out stuff. ghci's :info doesn't seem to work as nicely with type-families and data-families as it does with "plain" types: > :info Maybe data Maybe a = Nothing | Just a -- Defined in Data.Maybe ... > :info Persist.Key Potato -- "Key Potato" defined in example below data family Persist.Key val -- Defined in Database.Persist ... (no info on the structure/identity of the actual instance) One can always look for the instance in the source code, but sometimes it could be hard to find it and it may be hidden in template-haskell generated code etc. Code example: {-# LANGUAGE FlexibleInstances, GeneralizedNewtypeDeriving, MultiParamTypeClasses, TypeFamilies, QuasiQuotes #-} import qualified Database.Persist as Persist import Database.Persist.Sqlite as PSqlite PSqlite.persistSqlite [$persist| Potato name String isTasty Bool luckyNumber Int UniqueId name |] What's going on in the code example above is that Template-Haskell is generating code for us here. All the extensions above except for QuasiQuotes are required because the generated code uses them. I found out what Persist.Key Potato is by doing: -- test.hs: test = PSqlite.persistSqlite [$persist| ... -- ghci: > :l test.hs > import Language.Haskell.TH > import Data.List > runQ test >>= putStrLn . unlines . filter (isInfixOf "Key Potato") . lines . pprint where newtype Database.Persist.Key Potato = PotatoId Int64 type PotatoId = Database.Persist.Key Potato Question: Is there an easier way to get information on instances of type families and data families, using ghci or any other tool?

  • Adding an encapsulated email (like a forwarded email) from Zend Mail.

    - by Kieran
    I'm trying to get Zend_Mail to send an encapsulated message - as though it's forwarding an email. $attachedContent = "<h1>H1 Email</h1>"; $emailContent = "<h1>Email Content>"; $mail = new Zend_Mail(); $mail->setBodyText('text content'); $mail->setBodyHtml($emailContent); $mail->setFrom('[email protected]', 'GAS'); $mail->addTo('[email protected]', 'GAS'); $at = $mail->createAttachment($attachedContent); $at->type = 'message/rfc822; name="forwarded message"'; $at->disposition = Zend_Mime::DISPOSITION_INLINE; $at->encoding = Zend_Mime::ENCODING_7BIT; $mail->setSubject('Test'); $mail->send(); Mail clients are getting the email, rendering the normal HTML content, and displaying the forwarded message and rendering its contents, however, it's formatting like: <h1>Email Content</h1> Can you see what I'm doing wrong? I've not found anything online, and have tried my best to copy the formatting from looking at email source. Cheers, Kieran

  • Cocoa Core data: cannot save Created Items in NSTableview

    - by Paul Rostorp
    Hello, I'm am a beginner in mac os x development and am trying to get started with all this. Here is my problem : I've create a non-document based cocoa app using core data as storage. I've added an entity and attributes to the xdatamodel. In IB i've created an NSArrayController and linked it properly. I've created an nstableview binded to the nsarraycontroller. Next I added a button linked to nsarraycontroller with the " add: " method. When I try it out, I can add and edit the items in the table. Here comes the problem: Core data is supposed to save everything automatically, but to make sure i linked the "save" button in the menu to the appdelegate and to the " file's owner" , first responder, application... everything possible ( with both " save :" and " saveaction:" methods ). And still it doesn't save when clicking save: when I restart the cell created ( and renamed ) are gone. And also, I didn't even edit the source code yet; core data for such simple tasks is supposed to only need Interface builder. Please help me for this, I haven't found any threads resolving this problem. Thank you in advance.

  • .Net: What is your confident approach in "Catch" section of try-catch block, When developing CRUD op

    - by odiseh
    hi, I was wondering if there would be any confident approach for use in catch section of try-catch block when developing CRUD operations(specially when you use a Database as your data source) in .Net? well, what's your opinion about below lines? public int Insert(string name, Int32 employeeID, string createDate) { SqlConnection connection = new SqlConnection(); connection.ConnectionString = this._ConnectionString; try { SqlCommand command = connection.CreateCommand(); command.CommandType = CommandType.StoredProcedure; command.CommandText = "UnitInsert"; if (connection.State != ConnectionState.Open) connection.Open(); SqlCommandBuilder.DeriveParameters(command); command.Parameters["@Name"].Value = name; command.Parameters["@EmployeeID"].Value = employeeID; command.Parameters["@CreateDate"].Value = createDate; int i = command.ExecuteNonQuery(); command.Dispose(); return i; } catch { **// how do you "catch" any possible error here?** return 0; // } finally { connection.Close(); connection.Dispose(); connection = null; } }

  • How should I setup my Visual Studio projects/solutions in a Mercurial repository?

    - by Dave A
    At my company we have a few different web apps that each share some common libraries. The Visual Studio setup looks like this. Website 1 Solution Website 1 Shared Library 1 Project Shared Library 2 Project Website 2 Solution Website 2 Shared Library 1 Project Shared Library 2 Project Windows Service Solution Windows Service Project Shared Library 1 Project Shared Library 2 Project Shared Library Solution Shared Library 1 Project Shared Library 2 Project All Projects Solution Website 1 Website 2 Windows Service Project Shared Library 1 Project Shared Library 2 Project We want to start using Mercurial for source control, but I'm still not sure the best way to do it. From what I've read you're supposed to use a separate repository for each project. No problem there, but where do the Visual Studio solution files (.sln) go? Should there be a separate repository with just an .sln file? Ideally the projects that use the shared libraries should all use the same version, and the solution "All Projects Solution" should build without errors, but sometimes we need to branch the shared libraries. What is the best way to do this, and how would the repositories be setup? How do I get a working copy of a certain branch/tag of the Website 1 solution when every project is in a separate repository. Do I have to pull each one separately, or write a script to do it all at once? Can tortoise hg do that for me? Any other tips to make this process easier?

  • LINQ Query to DataTable.DataSource

    - by lumberjack
    I am trying to perform a LINQ query on a DataTable and show the result in another DataTable. My source DataTable looks something like this: DataTable myDataTable = new DataTable(); myDataTable.Columns.Add("OrderID", typeof(int)); myDataTable.Columns.Add("Date", typeof(DateTime)); myDataTable.Columns.Add("UnitsPurchased", typeof(int)); The resulting DataTable looks like this when filled: Order ID Date Units Purchased 16548 10/15/09 250 17984 11/03/09 512 20349 01/11/10 213 34872 01/15/10 175 My current LINQ query looks like this: IEnumerable<DataRow> query = (from row in myDataTable.AsEnumerable() where row.UnitsPurchased > 200 select new { row.OrderID, row.Date, row.UnitsPurchased }) as IEnumerable<DataRow>; resultDataTable.DataSource = query.CopyToDataTable<DataRow>(); Every time I run this code query is null. I can see that that the as IEnumerable<DataRow> is the culprit, but it makes no since to me since DataTable.AsEnumerable() returns an IEnumerable<DataRow>. Any help would be appreciated.

  • WPF Designer has bug with parsing generic control with overrided property

    I've created a generic lookless control with virtual property: public abstract class TestControlBase<TValue> : Control { public static readonly DependencyProperty ValueProperty; static TestControlBase() { ValueProperty = DependencyProperty.Register("Value", typeof(TValue), typeof(TestControlBase<TValue>)); } protected TestControlBase() { Focusable = false; Value = default(TValue); } public virtual TValue Value { get { return (TValue)GetValue(ValueProperty); } set { SetValue(ValueProperty, value); } } } Then I've made a control derived from it and overrided Value property: public class TestControl : TestControlBase<int> { public override int Value { get { return base.Value; } set { base.Value = value; } } } So I use it in a Window XAML: <TestControls:TestControl /> When I open window in designer all is OK, but when I put mouse cursor to this line, or to this control in designer I receive exception: Exception has been thrown by the target of an invocation. at System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) at System.Delegate.DynamicInvokeImpl(Object[] args) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) Ambiguous match found. at System.RuntimeType.GetPropertyImpl(String name, BindingFlags bindingAttr, Binder binder, Type returnType, Type[] types, ParameterModifier[] modifiers) at System.Type.GetProperty(String name) at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsDirect() at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsAttached() at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties(Attribute[] attributes) at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.TypeDescriptionNode.DefaultExtendedTypeDescriptor.System.ComponentModel.ICustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.GetPropertiesImpl(Object component, Attribute[] attributes, Boolean noCustomTypeDesc, Boolean noAttributes) at System.ComponentModel.TypeDescriptor.GetProperties(Object component) at MS.Internal.Model.ModelPropertyCollectionImpl.GetProperties(String propertyNameHint) at MS.Internal.Model.ModelPropertyCollectionImpl.<GetEnumerator>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.Model.ModelPropertyMerger.<GetFirstProperties>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.PropertyInspector.UpdateCategories(Selection selection) at MS.Internal.Designer.PropertyEditing.PropertyInspector.OnSelectionChangedIdle() Who know this problem?

  • Prevent illegal behavior to the registered user

    - by Al Kush
    I am building a website in which this website will be focused on the publishing of novels. Every writers who publish their novels with us will get a royalty from us. And this royalty comes from the user or the reader who read the novel online in our website. When a user search for a novel and want to read that, they will click a link to the page which its content is that novel. The html page for each novels will have a session function that first will force them to login or register to make a payment such as with a credit-card or paypal before accessing that html page. My problem now is if the user has succesfully login and access the html page, I am afraid if the user will copy the content of the novel. Some disccussion out here How to Disable Copy Paste (Browser) have a solution to create it in Flash so that it can't be coppied-paste. But the I think, if the user who access it is a web developer like us they will try to find the path of the file from the link in the page source, and then they can steal it. For now I think it is enough I am explaining this. I hope anyone fully accept this problem (question) with a good idea to solve it.

  • Function syntax puzzler in scalaz

    - by oxbow_lakes
    Following watching Nick Partidge's presentation on deriving scalaz, I got to looking at this example, which is just awesome: import scalaz._ import Scalaz._ def even(x: Int) : Validation[NonEmptyList[String], Int] = if (x % 2 ==0) x.success else "not even: %d".format(x).wrapNel.fail println( even(3) <|*|> even(5) ) //prints: Failure(NonEmptyList(not even: 3, not even: 5)) I was trying to understand what the <|*|> method was doing, here is the source code: def <|*|>[B](b: M[B])(implicit t: Functor[M], a: Apply[M]): M[(A, B)] = <**>(b, (_: A, _: B)) OK, that is fairly confusing (!) - but it references the <**> method, which is declared thus: def <**>[B, C](b: M[B], z: (A, B) => C)(implicit t: Functor[M], a: Apply[M]): M[C] = a(t.fmap(value, z.curried), b) So I have a few questions: How come the method appears to take a monad of one type parameter (M[B]) but can get passed a Validation (which has two type paremeters)? How does the syntax (_: A, _: B) define the function (A, B) => C which the 2nd method expects? It doesn't even define an output via =>

  • What ever happened to APL?

    - by lkessler
    When I was at University 30 years ago, I used a programming language called APL. I believe the acronym stood for "A Programming Language", This language was interpretive and was especially useful for array and matrix operations with powerful operators and library functions to help with that. Did you use APL? Is this language still in use anywhere? Is it still available, either commercially or open source? I remember the combinatorics assignment we had. It was complex. It took a week of work for people to program it in PL/1 and those programs ranged from 500 to 1000 lines long. I wrote it in APL in under an hour. I left it at 10 lines for readability, although I should have been a purist and worked another hour to get it into 1 line. The PL/1 programs took 1 or 2 minutes to run on the IBM mainframe and solve the problem. The computer charge was $20. My APL program took 2 hours to run and the charge was $1,500 which was paid for by our Computer Science Department's budget. That's when I realized that a week of my time is worth way more than saving some $'s in someone else's budget. I got an A+ in the course. p.s. Don't miss this presentation entitled: "APL one of the greatest programming languages ever"

  • Visual C++ Assembly link library troubles

    - by Sanarothe
    Hi. I'm having a problem having my projects built in VC++ Express 2008... I'm using a library, irvine32.inc/lib. INCLUDE Irvine32.inc works for me at school (On already configured VS environments) by default, but at home (Windows 7 x64) I'm having a boatload of issues. My original post here was that a file that irvine32.inc referenced, in the same folder, 'could not be opened.' Added irvine folder to the include path for specific project, progress. Then I was getting an error with mt.exe, but a suggestion on the MSDN suggested turn off antivirus, and now project does build but when I run a program that does NOT reference anything in irvine32, it tells me repeatedly that my project has triggered a breakpoint, and allows me to continue or break. Continue just pops the same window, break loads another popup telling me that "No symbols are loaded for any call stack frame. Source code cannot be displayed." This popup lets me view the disassembly. I tested it with and without working statements, it just throws the same breakpoint on the first line of code. Now, if I run the program when it DOES require something from the include file, in this case, DumpRegs: INCLUDE Irvine32.inc .data .code main PROC mov ebx,1000h mov eax,1000h add eax,ebx call DumpRegs main ENDP END main This gives me 1main.obj : error LNK2019: unresolved external symbol _DumpRegs@0 referenced in function _main@0 1C:\Users\Cameron\csis165\Lab8_CCarroll\Debug\Lab8_CCarroll.exe : fatal error LNK1120: 1 unresolved externals This does NOT happen when I build a project from the book author's examples, which has the same include statement. I'm baffled. :(

  • CQRS - The query side

    - by mattcodes
    A lot of the blogsphere articles related to CQRS (command query repsonsibility) seperation seem to imply that all screens/viewmodels are flat. e.g. Name, Age, Location Of Birth etc.. and thus the suggestion that implementation wise we stick them into fast read source etc.. single table per view mySQL etc.. and pull them out with something like primitive SqlDataReader, kick that nasty nhibernate ORM etc.. However, whilst I agree that domain models dont mapped well to most screens, many of the screens that I work with are more dimensional, and Im sure this is pretty common in LOB apps. So my question is how are people handling screen where by for example it displays a summary of customer details and then a list of their orders with a [more detail] link etc.... I thought about keeping with the straight forward SQL query to the Query Database breaking off the outer join so can build a suitable ViewModel to View but it seems like overkill? Alternatively (this is starting to feel yuck) in CustomerSummaryView table have a text/big (whatever the type is in your DB) column called Orders, and the columns for the Order summary screen grid are seperated by , and rows by |. Even with XML datatype it still feeel dirty. Any thoughts on an optimal practice?

  • UIView coordinate transforms on rotation during keyboard appearance

    - by SG
    iPad app; I'm trying to resize my view when the keyboard appears. It amounts to calling this code at appropriate times: CGRect adjustedFrame = self.frame; adjustedFrame.size.height -= keyboardFrame.size.height; [self setFrame:adjustedFrame]; Using this technique for a view contained in a uisplitview-based app works in all 4 orientations, but I've since discovered that a vanilla uiview-based app does not work. What happens is that apparently the uisplitview is smart enough to convert the coordinates of its subviews (their frame) such that the origin is in the "viewer's top left" regardless of the orientation. However, a uiview is not able to correctly report these coordinates. Though the origin is reported as (0,0) in all orientations, the view's effective origin is always as if the ipad were upright. What is weird about this is that the view correctly rotates and draws, but it always originates in the literal device top left. How can I get the view to correctly make its origin the "top left" to the viewer, not the device's fixed top left? What am I missing? Please, for something so trivial I've spent about 6 hours on this already with every brute force technique and research angle I could think of. This is the original source which doesn't work in this case: http://stackoverflow.com/questions/1951826/move-up-uitoolbar

  • How to compile a C DLL for 64 bit with Visual Studio 2010?

    - by Daren Thomas
    I have a DLL written in C in source code. This is the code for the General Polygon Clipper (in case you are interested). I'm using it in a C# project via the C# wrapper provided on the homepage. This comes with a precompiled DLL. Since switching to a 64bit Development machine with Visual Studio 2010 and Windows 7 64 bit, the application won't run anymore. This is the error I get: An attempt was made to load a program with an incorrect format. This is because of DLLImporting the 32bit gpc.dll, as I have gathered from stuff found on the web. I assume this will all go away if I recompile the DLL to 64bit, but can't for the love of me figure out how to do so. My C skills are basic, in that I can write a C program with the GNU tools, but have no experience with various compilers / processors / IDEs etc. I believe I could port this to C#. By that I mean I trust myself to actually pull it off. But I'd prefer not to, since it is a lot of work that I'd prefer a compiler to do for me ;)

  • Dynamic Connection Strings for Strongly Typed DataSet in a Class Library using App.Config

    - by Luc
    This is my first question on StackOverflow.com and I'm not sure if this is the correct way to do this. I found a similar question titled: Modifying the Data Source for the Strongly Typed Dataset Connection String. However, the answer provided is not working for me. I'm not able to comment on it because I don't have enough "reputation points" (again, I just signed up), and I didn't want to provide an "answer", because I don't know the correct answer. My problem is that I need to be able to modify the connection string inside the generated myproject.dll.config file, but doing so has no effect for me at all. My library still uses the default connection string that was setup at design time. I've tried everything I know to try, but still no luck. I've tried working around the issue using multiple different approaches, but still the problem persists. I can't find any help on the internet with my specific problem either. It would be great if somebody could shed some light as to why my modified config file isn't being read. Useful information: I'm using a Strongly Typed DataSet I don't know the actual connection string at design time. The app.config doesn't allow me to specify a 'User' scoped connection string. I'm tied to a class library (no Windows Forms) Thank you for any help! Luc

  • C# WPF DataBind boolean

    - by jtdangelo
    I have been using this website to learn a lot about C# for a while, but this is my first time posting a question. I look forward to hearing back from some of the seasoned C# veterans! I have been working on a C# 4.0 WPF project and need to figure out how to databind a boolean value. I have a reference to my Application.Current object in a window. My "App" object contains a boolean field called "Downloaded" that is true if the user has downloaded information from a web service. I need to databind a textbox's IsEnabled field to this Downloaded value. Any tips? Here is what I have come up with so far. (Any useful links to better learn WPF XAML are greatly appreciated!) C# Code: class MainWindow : Window { ... private App MyApp = App.Current as App; ... } XAML: <TextBox ... IsEnabled="{Binding Source=MyApp, Path=Downloaded}" /> James
