• Visual Studio How to support Exception Assistant

  I want to support an exception assistant to COBOL Exceptions. How can it support It seems that it has realized by putting an XML file on the   ExceptionAssistantContent folder of an IDE folder about the standard exception for Visual Studio. Best Regards. Hi Shinya, it appears that ExceptionAssistant is supported for VB.NET, C#, and J#.  I do not see any extensibility points to add languages.  You are correct that the exception database is in the form of the DefaultContent.xml in the folder you mentioned above.  The Exception manager will also read additional *.xm ...Show All

• Visual Studio 2008 (Pre-release) How to animate a custom control?

  As far as I know, the DependencyProperty could be animated, it's simple to use this feature in XAML, we could indicate the animation target name like: "Rectangle.Width", etc. but when I use a custom control, say "MyButton", it has a DependencyProperty "Value", I could use "MyButton" in XAML like: <Window x:Class="MyUserControl.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:uc="clr-namespace:MyUserControl"> <Grid> <uc:MyButton/> </Grid> but how c ...Show All

• Windows Forms Rectangles with different Pen widths

  I've noticed some issues with the Graphics class in the way it draws rectangles and I'm wondering if there's any advice around dealing with these issues (my searches came up with nothing so far). For example, when I draw a rectangle with two different pen widths the rectangles are not contained in the same dimensions. Pen pen2 = new Pen(Color.FromKnownColor(KnownColor.Highlight), 2.0f); Pen pen1 = new Pen(Color.FromKnownColor(KnownColor.Red)); pen2.Alignment = System.Drawing.Drawing2D.PenAlignment.Inset; pen1.Alignment = System.Drawing.Drawing2D.PenAlignment.Inset; g.DrawRectangle(pen1, new Rectangle(10, 10, 10, 10)); g.DrawRec ...Show All

• Visual C++ Exporting functions with _declspec(dllexport)

  Hi, I have a DLL library and I export classes from this library. All classes and their method are properly exported and can be seen in "dumpbin /symbols mydll.dll" output. I use the standard _declspec(dllexport) and _declspec(dllimport) approach. All classes lie under a namespace like: namespace MyDLL {   MYDLL_EXPORT void init() ; // Implemented in MyDLL.cpp   class MYDLL_EXPORT MyClass // Methods Implemented in MyDLL.cpp   {   } } I have another project which tries to link with the DLL and the linker can not resolve the MyDLL::init() function. The output of " dumpbin /symbols MyDLL.dll " also doesn't show a init ...Show All

• Software Development for Windows Vista Embedding Activity Designer? (like Workflow Designer in Lab10)

  Hi, is it possible to embed the Activity Designer (just like Workflow Designer) into a Windows Forms application Thanks in advance, Osi Ok, i've found it :) Actually this Workflow Designer (described in HOL10) can also be used to design Activities (workflows are also "special" activities). If we change in WorkflowDesignerControl.cs the type of the Workflow (this.workflow) eg. to SequenceActivity (instead of SequentialWorkflowActivity), then the designer will also look like the "activity designer" in VS. ...Show All

• SQL Server Flat File Destination

  I have a red link from my OLE DB Destination to my Flat File Destination.  I'm not sure why it's read but the OLE DB shoves some data into a table.  I want to then take that data and move it into a flat file using the flat File Destination step but when I run my project, it shows the Flat File Destination Step green but my flat file shows nothing at the end. I'm not sure what I'm doing wrong but the line linking the two is still red.  Check out my picture here:  http://www.photopizzaz.biz/junk/1.jpg and then the properties of my flat file destination module: http://www.photopizzaz.biz/junk/2.jpg http://www. ...Show All

• Windows Forms Formdesigner doesn't display controls

  Hi, I have a problem with the form designer in VS2005 professional. My Form holds two TabControls, one in the other (placed ond a tabPage). The one on the TabPage again has a couple of TabPages. One of them holds a SplitContainer in which I placed a ToolStrip and a DataGridView. The Problem now is, that if I click on the tabpage holding the splitcontainer the tabpage doesn't show any controls any more. If I close my project and reopen it, the controls are there again, but just for a short time. Is it something I am doing wrong, or does the Formdesigner have a problem Thanks for hints an answers.
