• Visual Studio Help using the Visual Studio DIA SDK for debugging...

  I’m trying to provide myself a call stack dump whenever my code causes an exception, and I want to use the DIA SDK rather than ImageHlp API. Ie I want to see the callstack when my program crashes, rather like the callstack is shown in VisualStudio, except I’m not using an out of process debugger – I want to do this in my own app. The DIA SDK provides some COM interfaces to support what I want to do, but unfortunately there is no documentation. All I know is that IDiaStackWalkerHelper and IDiaStackWalkFrame must be implemented by the client. As to exactly how, remains a mystery! And this is where you step in! Let me give you an example using a diagram to show where I'm at. Go here to view a picture of the class ...Show All

• Visual C# For Statement Help please

  I'm translating a project from VB6 to C#.NET 2.0 and having a bit of trouble with this For statement for some odd reason...

• Software Development for Windows Vista InkCanvas "Children" Serialization Deserialization

  Hello, Does the serialization and deserialization in InkCanvas save and restore the children elements like those in InkCanvasClipboard example My quick (and possibly incorrect) test showed that it didn't. I did a quick mod to the InkSerialization sample by adding Ellipse shape but it didn't seem to restore it. I would appreciate guidance. Regards, Vinay Agarwal Hello Vinay, Yes, if you use XamlWriter.Save() and XamlReader.Load() with an InkCanvas, its children are being included in the serialization and deserialization process. Here is a quick way to demo this without writing any code: - open up XamlPad - paste in the below XAML (or any other XAML that contains an InkCanvas with child elements) ...Show All

• Windows Forms Event-based Asynchronous Pattern: exceptions re-thrown loose stack trace?

  Hi. When you use the Event-based Asynchronous Pattern , you have a background thread that can use one AsyncOperation objet to post messages to the calling thread (UI thread in most cases). While posting a progress message may never be a problem, you may also post some more important messages to the calling thread. In that case the calling thread may throw an exception telling he couldn't handle the message. Someone must catch these exceptions. So when the calling thread throws an exception, I let the backgournd thread get notified of it, so that he can stop if necessary. In my case I have a "async inside" object that hides the async mode. It has a ShowModal() function that displays a progress form. This function exits when the pro ...Show All

• Visual Studio 2008 (Pre-release) Floating UI Elements in a FlowDocument

  Okay, so this time last year I was playing a bit with Avalon.. Now I'm writing up an architecture review of WPF and doing a couple of POCs. Read the book by Chris Sells and co. and Implemented some nice XAML with some controls floated in a TextFlow... Unfortunately Chris and co wrote that the same time I was playing with Avalon and the FlowDocument is now it. Problem is that I can't seem to find a way to float the controls in it. I did, finally manage to find a combination of Figure, FlowDocumentViewer (FlowDocumentScrollViewer seems to prevent the figure flowing) that would flow a paragraph, but when I stuck in a TextBlock or Button populated BlockUIContainer then all the flow went. Seems that unless I hardcoded the width of the contained ...Show All

• .NET Development I fixed by OutOfMemory Exceptions. Can somebody tell me why???

  I have written/deployed a C# Windows Service using VS.NET 2003. This service, over a period of several days, would grow in size to over 700 meg and start getting OutOfMemory exceptions. Also, the Page Faults would number in the millions. The problem turned out to be in class level 2 XmlDocument objects. (Note: The class that used these 2 XmlDocument objects was a very busy class). The class would use these 2 XmlDocument objects to manipulate XML strings. The LoadXml() method was used to load the XML and then manipulate the XML as needed. There were 3 methods in this class that used these class level XmlDocument objects. So, I deleted these class level XmlDocument objects and used local XmlDocument objects within each method that requ ...Show All
