[Solved] The Command CreateProcess C++

by


If you just want to open an existing image using defualt app then use ShellExectue API. For example:

ShellExecuteW(NULL, L"open", L"Z:\\cat.PNG", NULL, NULL, SW_SHOW);

You could also open image with mspaint using the same API:

ShellExecuteW(NULL, L"open", L"C:\\Windows\\system32\\mspaint.exe", L"Z:\\cat.PNG", NULL, SW_SHOW);

ShellExecuteEx will let you wait for finishing process.

You can do the same using CreateProcess. As @DavidHeffernan pointed out the second parameter of CreateProcess should point to writable memory else it will raise access violation. To make it clear I will just omit the first parameter. Example:

STARTUPINFOW process_startup_info{ 0 };
process_startup_info.cb = sizeof(process_startup_info); // setup size of strcture in bytes

PROCESS_INFORMATION process_info{ 0 };

wchar_t commandline_args[] = L"\"C:\\Windows\\system32\\mspaint.exe\" Z:\\cat.PNG";

if (CreateProcessW(NULL, commandline_args, NULL, NULL, TRUE, 0, NULL, NULL, &process_startup_info, &process_info))
{
    //WaitForSingleObject(process_info.hProcess, INFINITE); // uncomment to wait till process finish
    CloseHandle(process_info.hProcess);
    CloseHandle(process_info.hThread);
}

I strongly recommend to read this CodeProject article (A newbie’s elementary guide to spawning processes).
