Can I run the program directly in C?

finzzers

For example, my U disk, I copy QQ to the Tencent directory of the U disk, and then I want to write an autorun.exe file in C language, when running this file, Tencent\qq.exe will be run, and in order to use it on different machines I require the use of relative directories. How can I achieve this? Thank you !!!!

ShellExecute
Or CreateProcess
As for the directory problem, the absolute directory and the relative directory are the same. If the program and the Tencent directory are located in the same directory, the path .\Tencent\qq.exe can be used. As for the program on the u disk or the hard disk, it is the same.

Command line: start (parameter setting, see start /?) "Tencent\qq.exe"
c: system ("start ...");
Of course the upstairs is more formal

orangedj

system ("C:\\...\\qq.exe");

I don't know too much, can you give me a code, QQ is in the Tencent directory in the root directory of the USB flash drive, that is, the path of QQ is X:\Tencent\QQ.exe, and autorun.exe is in the root directory of the USB flash drive. How can I write it in C? Thank you , Preferably TC2.0.

#include <windows.h>
int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
                    PSTR szCmdLine, int iCmdShow)
{
HINSTANCE result = ShellExecute (NULL, _T ("open"), _T (".\Tencent\qq.exe"), NULL, NULL, SW_SHOW);
return 0;
}
There is no tc on hand, this is under vc.

Simply look for the mobile storage device first, and then go to the root directory of this device to find QQ.exe recursively, and then find CreateProcess (), or WinExec ().
Of course, first of all, that machine needs to support your USB flash drive, can detect the plug-in status of your USB flash drive, and then, hey, it is not easy to detect the status of a certain storage device.

Is C ???
I don't know, MFC can call the dos command with ShellExecute or cmd.
