You should use corresponding socket API's, instead of following this approach.
However, you can refer Console functions[^], and see what fits your needs.

Thanks for your reply. But actually I used the netsend command for example purpose only. I want to use some commands like cd directory, cd.., and run some .exe from console.
Can you help me in that ?
Thanks for your prompt reply.

There is equivalent of very command you like to run from command prompt. You can use CreateDirectory in this case.

You can use ShellExecure, CreateProcess for this purpose. Refer its documentation.

The error you mentioned is obvioulsy runtime error, not compliation error. Try to debug the code, giving you this problem.
Post some relevent code , to asses the problem.

Hi, I am using the Visual Studio 2005 Professional with SP1. When I tried to create my own custom control as described in "Creating Custom Controls By Chris Maunder" and "Creating and Using custom controls in VC++ By Yogesh M Joshi" (thanks to them by the way... ). In debug mode, program exits as soon as it starts with a memory leak error.
The steps I took to create the control is as follows,
1) I created a dialog based application (Unicode support & Static Library).
2) I created a new MFC class named "CMyCustomClass" which inherits from CView.
3) I declared and defined a public function to register the class. Code of this classs is given below
#define CLASS_NAME _T("CustomClassCtrl")
BOOL CMyCustomClass::RegisterScreenSaverClass(void)
{
HINSTANCE hInst = ::AfxGetInstanceHandle();
WNDCLASS wndcls;
if (!(::GetClassInfo(hInst, CLASS_NAME, &wndcls)))
{
wndcls.style = CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;
wndcls.lpfnWndProc = AfxWndProc;
wndcls.cbClsExtra = wndcls.cbWndExtra = 0;
wndcls.hInstance = hInst;
wndcls.hIcon = NULL;
wndcls.hCursor = ::AfxGetApp()->LoadStandardCursor(IDC_ARROW);
wndcls.hbrBackground = (HBRUSH)::GetStockObject(WHITE_BRUSH);
wndcls.lpszMenuName = NULL;
wndcls.lpszClassName = CLASS_NAME;
if (!AfxRegisterClass(&wndcls))
{
::AfxThrowResourceException();
return FALSE;
}
}
return TRUE;
}
4) I called this function from "CMyCustomClass" constructor.
5) I dragged and droped a custom control in the dialog window and set its class name as "CustomClassCtrl".
6) There is no more addion to the project just these steps.
7) When I compile and run the code. The following error occurs. (By the way I couldn't understand why dumping objects announced a path in drive "f:", my Visual Studio is installed in "c:")
Detected memory leaks!
Dumping objects ->
f:\sp\vctools\vc7libs\ship\atlmfc\src\mfc\occmgr.cpp(195) : {69} normal block at 0x003F4AE8, 24 bytes long.
Data: < > 01 00 00 00 00 00 00 00 02 00 00 00 00 00 00 00
{68} normal block at 0x003F8F98, 16 bytes long.
Data: < > FF FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00
Object dump complete.
The program '[2672] Screen Saver.exe: Native' has exited with code 0 (0x0)
I have been searching for the answer for a long time now and found none yet...
Thanks for all the help.
