Use Win32 API CreateProcess () to create a DOS program without a window

DoSProgramThere are two possibilities:

First, when creating the DOS process, specify not to create a window;

Second, there is a window to hide the DOS process.

According to msdn, the CreateProcess () API prototype is as follows:

Bool CreateProcess (

Lptstr lpapplicationname,

Lptstr lpcommandline,

Lpsecurity_attributes lpprocessattributes,

Lpsecurity_attributes lpthreadattributes,

Bool binherithandles,

DWORD dwcreationflags,

Lpvoid lpenvironment,

Maid directory,

Lpstartupinfo,

Lpprocess_information lpprocessinformation

);

Specify dwcreationflagsCreate_no_window

,Create a DOS process without creating a window.

The lpstartupinfo parameter is in the startupinfo structure again, as follows:

Typedef struct _ startupinfo {

Dword cb;

Lptstr lpreserved;

Lptstr lpdesktop;

Lptstr lptitle;

DWORD dwx;

DWORD dwy;

DWORD dwxsize;

DWORD dwysize;

DWORD dwxcountchars;

DWORD dwycountchars;

DWORD dwfillattribute;

DWORD dwflags;

Word wshowwindow;

Word cbreserved2;

Lpbyte lpreserved2;

Handle hstdinput;

Handle hstdoutput;

Handle hstderror;

} Startupinfo, * lpstartupinfo;

Specify the word wshowwindow in the startupinfo structure as sw_hide, that is, the DOS process is created in the non-display window mode.

In visusl Studio 2005, the test result is: Create a [CMD/C] dos process. The first method is to create a DOS process without a window, the second method does not properly hide the DOS window.

An instance for service installation:

Cstring scommand = "+ sserviceexefilepath +" + "" + "-install ";

Startupinfo Si;
Process_information PI;
Memset (& Si, 0, sizeof (SI ));
Si. cb = sizeof (SI );
If (CreateProcess (null, (char *) (lpctstr) scommand), null, null, false, 0, null, null, & Si, & PI ))
{
Waitforsingleobject (PI. hprocess, infinite );
Bret = true;
}

Closehandle (PI. hthread );
Closehandle (PI. hprocess );
