Thread: process finding

hi
I wrote a small code to find a specific process (in this case the notepad.exe).It compiles Ok but it wont identify the notepad. any one know why???
I'm using VC++ 6.0

here is the code

Code:

#include <windows.h>
#include <stdio.h>
#include <Tlhelp32.h>

void getprocess();

PROCESSENTRY32 pr;
HANDLE hpro;
BOOL test=TRUE;

int main(void){
getprocess();
	return 0;
}

void getprocess(){
hpro=CreateToolhelp32Snapshot(TH32CS_SNAPALL,0);
pr.dwSize=sizeof(PROCESSENTRY32);

Process32First(hpro,&pr);

while(test==TRUE){
test=Process32Next(hpro,&pr);

if(pr.szExeFile == "notepad.exe"){
MessageBox(NULL,"Notepad is running","Messenger",MB_OK);
}

printf(pr.szExeFile);
printf("\n");
}

CloseHandle(hpro);  
}

okay guys its working
but why the

Code:

if(pr.szExeFile == "notepad.exe")

is not working ??
thanks

Code:

if(!strcmp(pr.szExeFile, "notepad.exe"))
//Rather than
if(strcmp(pr.szExeFile, "notepad.exe")
//Which is testing if they are not equal

No, not really.

However, a character array becomes a pointer, and same with string literals. This means that you're essentially comparing the addresses of the variables, but that's just because that 'variable itself' contains an address(eg. a pointer).

Any normal variables (int and char, etc) that aren't pointers are compared the same way - the value that's stored is compared.

hi
thank you all for the replies
