  How do I run another application from an application using a button Is there a function in Visual C++ to do it You have CreateProcess API and ShellExecute / ShellExecuteEx at your disposal.

• SShor How can I limit the no of lines in an EditBox

  Hello, How can I limit the no of lines allowed in a multiline CEditBox Thanks and Regards Shibu Hello The more appropriate place for your question is probably the MFC newsgroup: http://msdn.microsoft.com/newsgroups/default.aspx dg=microsoft.public.vc.mfc&lang=en&cr=US Thanks Damien ok. But what should I do, if it reaches the maximum line of limit regards..shibu. Perhaps there is a solution to your problem, but in my opinion you should not limit the user’s relish to edit a text in a multi-line editor. She/He probably should be able to have an intermediate text longer then required, to freely copy and paste fragments etc. I would just check the number o ...Show All

• SNOMan CWinFormsControl and VC.NEt

  1) Is CWinFormsControl supported by VC.NET 2) How would I use a .NET control in native code in VC.NET. I wrote some code in VC2005 using the CWinFormsControl class. I included afxwinforms.h in my stdafx.h file to facilitate the class. But when I tried running the code under CV.NET it said that afxwinforms wasn't found. So my question is: Is CWinFormsControl supported by VC.NET . and if so do include afxwinforms.h or something else. and if this is not supported by VC.NET how would I use a .NET control in native code in VC.NET. Thanks! is there some alternative for using a managed control that is analogous to CWinFormsControl Nope, VS2003 doesn't have afxwinforms.h bahh... nevermind.. I talked my ...Show All

• Sergey Sorokin 32bit console app on Vista x64

  I'm trying to compile a simple 32 bit console application using VS2005 (C++ obviously) on Vista x64. The compiler gives me "Error result 255 returned from 'C:\Windows\SysWow64\cmd.exe'" and when I try to manulally run the 32bit cmd.exe above it tells me that it has been disabled by the administrator. I don't remember doing this, so it must have been a default setting or something. I haven't been able to find out how to enable the command prompt, and I'm not sure that would fix the problem. Any Ideas Thanks, Brady hello Re: 32bit console app on Vista x64 such question is currently not covered in the scope of this forum, for the scope of visual c++ general forum please refer to: http://fo ...Show All

• Fox Me Up how can i turn off the "/gs" flag ?

  i hope im in the right forum.. im using MSVC++6 and i want to turn off the /GS flag, how can i do this thanks ! im so sure that VC6 is not support this option.. where did i need to write it in my program i mean after the "include..." and before the "int main()" or where and what is the syntax thanks ! Umh, I'm certain you know that already, but obviously /GS or /GS- are command line options that are passed to the compiler driver (cl.exe) on the command line. You can always look these up in the index of MSDN Library to find the corresponding setting in the IDE. So, it is nothing you would do in the source code. Are you sure you mean /GS (and not /Gs) There's probably a corresponding pr ...Show All

• Trevin Chow SerialPort hell

  Hey all, I am communicating with an old HP 8591C Spectrum Analyzer via serial port. If i use hyperterminal, the device responds to commands A LETTER AT A TIME!!! It is so frustrating that it doesn't wait for a carriage return. Into the dotnet world. I've tried a million times to make the serialPort control do this. For example: // This doesn't work serialPort->Write("ST 500MS" + "\r"); // Nor does this serialPort->WriteLine("ST 500MS"); // Nor does this serialPort->Write('S'); serialPort->Write('T'); serialPort->Write(' '); serialPort->Write('5'); ...... Any ideas as to why keystrokes in hyperterm get processed, but my individual writes do not ...Show All

• AKINAL How to replace the MFC icon at mainframe with a custon icon

  Hi, I'd like to know how to change the MFC default icon with a custom one in the mainframe of a MFC program, as well, the icon in the exe file name. Please help. Thanks. Jason Zhang Thanks for the reply. I did draw a new icon with the resource editor and it only works with the Help dialog not the mainframe. That's the 32x32 pixel one, but I can't find the small template to edit. Is that the reason that it doesn't work with the mainframe and the application exacutable name icon Thanks. Jason Got it. But do you happen to know how to reduce the icon from 32x32 to 16x16 pixels, and how to show the same custom icon in the name of the application in Windows e ...Show All
