• .NET Development Delegate callback to non-static function in unmanaged class with managed reference argument

  Dear Sir! Could you please advise me of how I can implement a delegate callback to a non-static function in an unmanaged class using managed reference argument. I have tried implementing this using the GetDelegateForFunctionPointer(). I can't use unmanaged types in the GetDelegateForFunctionPointer() function and don't know how to convert the unmanaged function pointer to an IntPtr. Also, the managed argument is lost when performing the delegate call. I have made a testapp that demonstrates my approach. Copy the following code into a C++ CLR console application: <code start> // DemoApp002.cpp : main project file. ...Show All

• .NET Development .NET FrameWork version used.

  Hi   I have an assembly that is built against the mscorlib 1.0.3300.0 .NET 1.0 that is using the System.Environment.Version to determine which version of the Framework it’s using to generate source code correctly.   (Were to include the Strong Name key file in the assemblyInfo.cs file or on the build command line.) When I build the assembly I don’t know what version of the .NET Framework the customers will be using.     When I run it on a machine that only has .NET Framework 1.1 and 2.0 on it the version always reports it’s   2.0.   I have run the sdkvars.bat to set up the 1.1 environ ...Show All

• Visual C# How to auto. show the SHORTCUT to a field?

  Hi, I have this problem.   When my form loads the user has to press the Alter Key to show all the shortcuts (i.e.  Alt+a, Alt+b etc.) for the textboxes.   The shortcuts is shown as an underlining of the charater in the textbox lebel of theleft of it. As you open the form the textbox lables do not show the shortcut or access key underlined. How do you show them as soon as the form is activated/displayed WITHOUT the need for the user to press the ALTER key Thanks & Regards, MCFS Hi, Hmmm. A very great workaround there Kodiya.

• Visual Basic custom shape forms

  I have tried to follow the example in the MSDN library but I cannot get it to work. I have created my shape in paint and chosen an easy background colour e.g. white and set the TranparencyKey but it doesn't work. Is there anything that I am doing wrong I've followed the instructions to the letter but it still doesn't work. Any ideas I'm running Visual Studio 2003 with the .NET 2.0 framework. Cheers I am having the same problem. May I ask were you set the color depth. Is it in the windows video setup, or in the vb app itself. John ...Show All

• .NET Development ASMX locking up. ASP.NET bug or a feature?

  My ASMX web service randomly locks up on a connection, and when it does the timeout is close to 15-minutes.  I have a winform polling the webservice every 10 seconds or so.  The weird thing is that subsequent connections to the web service works, so the web service isn't down for new connections, just a particular existing one.  And this isn't consistent, as in it sometimes happens and sometimes doesn't, so trying to catch it with debug is nearly impossible.  Also, it doesn't happen in the test environment, just on the production one.  What's even stranger is tha ...Show All

• .NET Development SIMD and the CLR

  Does the CLR natively support SIMD operations, such as SSE2 or 3DNow! I'm afraid I'm going to have to bump this, I think a week is long enough ;) The only way I can think of is by using intrinsics in a C++/CLI library, and calling it from another assembley, but I would prefer to know how to do it from within any language. So, any help ...Show All

• Visual Basic Printing with full PageBounds

  Hi, I need to print some custom drawings on the whole paper surface. I wanted to use the pagebounds width and height but i still have 100 pixels margins. What do i have to do to bypass those margins. The papersize width is 1169 Pix, i want a 1169 pix Line. I did try to set the PrintPageEventArgs.pagesettings.margins.[top-left-right-bottom] to zero(0), but it still doesn't work. Any idea Thanks in advance. Serge Hi Serge, Most likely this is a limitation of the printer - most printers aren't capable of printing to the edges of the paper. Steve Hoag ...Show All

• Visual C# Listview display...

  How to view a set of data in list view -Khamal- Could you be more specific   Are you binding a static list, dynamic list, DataTable, etc For static lists or even dynamic lists you can simply call listview.Items.Add() to add one or more items to the control.  For truly static items (a rare thing) then you can do it at design time through the designer. For arrays, data tables, etc. you can't use the normal method of setting the DataSource property because ListView doesn't have one.  The article http://www.codeproject.com/cs/miscctrl/ListView_DataBinding.asp provides an example of how to do it anyway.  For .NET 2.0 ...Show All
