• Visual C++ redirecting stdin/stdout/stderr for windows console

  Hello I want to redirect stdin/stdout/stderr of any console app to a pipe. the technique given in the relevant MSDN sample( http://msdn.microsoft.com/library/default.asp url=/library/en-us/dllproc/base/creating_a_child_process_with_redirected_input_and_output.asp ) does not output to the pipe in case the child process uses printf() statements.. although if the child uses _write(), the output is redirected to the pipe correctly. I beleive this has something to do with the C-runtime printf function buffering data in i/o buffers before output. How does one redirect output in case the child process uses functions like printf Plea ...Show All

• Smart Device Development delegates in CF 1.0

  All, We got sick of trying to distribute the CF 2.0 so we went back to CF 1.0. Now I need to setup delegates but they don't seem to work the same. I have the following code: delegate bool LoadForm ( byte [] data); public class SampleForm : System.Windows.Forms. Form { public bool LoadPForm( byte [] data) //Called from another Thread { LoadForm lf = LoadFields; return lf(data); } static bool LoadFields( byte [] data) //This should be called from the Thread of this form { //LOAD SOME FIELDS HERE return true ; } } This gives me an error: LoadFields (byte[])' referenc ...Show All

• .NET Development variable name from string?

  If I have an int like: int i = 1; and I have a string representing int i like: string name = "i"; is there a way I can turn the "i" into a variable name to access it's value   Mike Stall wrote: Unfortunately, you can't do it. This is a feature request we've gotten for future versions. Daniel - this is useful for certain dynamic languages (like Python). You'll notice that my code didn't use a variable called i. I just associated an arbitrary name with the integer. It's only a workaround to access any variable by a name (not it's name). ...Show All

• Windows Forms Clearing the Graphics Buffer

  I know in C# there exists a function Clear(Color c) for the graphics object. However, this method doesn't really clear the graphics on screen, all it really does is the FillRectangle function with a specified color for the length and width of the entire screen. What I want is something that truly clears out the screen, not some sort of mask to cover what was previously drawn. In my search I've found nothing on this topic, however, I have discovered something interesting that I think would helpful for this problem. Try this experiment: Create a windows application project in VS and add a panel to the form. Within the panel, make it so that it ...Show All

• Visual C# Where is vsvars32.bat ?

  Hi, I have installed VC# express 2005 final on 2 computers. On one, I can find vsvars32.bat in the Common7\Tools folder. This folder also contains a lot of other things. On the second machine the same folder Tools only contains a subfolder VDT. There is no vsvars32.bat and all the other stuff. I tried to repair/uninstall/reinstall but still the same. Thank you for your help Nicolas Not really, no. I haven't used VC# Express but the various beta and final versions of Visual Studio 2005 that I had installed always properly created their Common7\Tools directory tree with a vsvars32.bat file inside.

• Visual Studio A Software Factory Newbie Wants To Undersand Some Things....

  First of all to Jack Greenfield and Keith Short, the Software Factories book is just an incredible piece of work.
