چرا متود CreateProcessA اجرا نمی کنه؟!

من این رو توی یک dll استفاده کردم (dynamic) ولی موقع استفاده چیزی اجرا نمی کنه!!!! چرا؟!

#include <Windows.h>

#include <stdio.h>

void start(LPCSTR lpApplicationName,LPSTR Params)

{

    // additional information

    STARTUPINFOA si;

    PROCESS_INFORMATION pi;





    // set the size of the structures

    ZeroMemory(&si, sizeof(si));

    si.cb = sizeof(si);

    ZeroMemory(&pi, sizeof(pi));





    // start the program up

    CreateProcessA

    (

        lpApplicationName,   // the path

        Params,                // Command line

        NULL,                   // Process handle not inheritable

        NULL,                   // Thread handle not inheritable

        FALSE,                  // Set handle inheritance to FALSE

        CREATE_NEW_CONSOLE,     // Opens file in a separate console

        NULL,           // Use parent's environment block

        NULL,           // Use parent's starting directory 

        &si,            // Pointer to STARTUPINFO structure

        &pi           // Pointer to PROCESS_INFORMATION structure

    );

        // Close process and thread handles. 

       // CloseHandle(pi.hProcess);

       // CloseHandle(pi.hThread);

}

استفاده:

#include "Explore.h"





int main() {

		start("Explorer.exe",".");

	//getchar();

		return 0;

}

این کد در یک کتابخانه پویا استفده شده بود که هیدر کتابخونه بهش include نشده بود:

#include <stdio.h>

#include <Windows.h>

#include "process.h"

int process(LPCSTR lpApplicationName, LPSTR Params)

{

	// additional information

	STARTUPINFOA si;

	PROCESS_INFORMATION pi;





	// set the size of the structures

	ZeroMemory(&si, sizeof(si));

	si.cb = sizeof(si);

	ZeroMemory(&pi, sizeof(pi));





	// start the program up

	CreateProcessA

	(

		lpApplicationName,   // the path

		Params,                // Command line

		NULL,                   // Process handle not inheritable

		NULL,                   // Thread handle not inheritable

		FALSE,                  // Set handle inheritance to FALSE

		CREATE_NEW_CONSOLE,     // Opens file in a separate console

		NULL,           // Use parent's environment block

		NULL,           // Use parent's starting directory 

		&si,            // Pointer to STARTUPINFO structure

		&pi           // Pointer to PROCESS_INFORMATION structure

	);

	// Close process and thread handles. 

    CloseHandle(pi.hProcess);

    CloseHandle(pi.hThread);

	return 0;
