How to find Current Process Name

Question

I want to find the name of my current process .I have the currentprocessid .

please tell me how to find the name.

Answer 1

Use GetModuleFileName with NULL first argument to get the full path. Then use _tsplitpath with path and fname non-null arguments to extract only the name.

Answer 2

There are n no of method .Depend on your application type etc  Like you can use command line argument too and PROCESSENTRY32 etc. Second thing Most of the GetModuleName, QueryFullProcessImage name, etc., require a handle and thus won't be of much use. Toolhelp does return process name . For more detail have a look inside MSDN

void showProcessInformation() 
{    
 HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);  
 if(hSnapshot)
   {        
     PROCESSENTRY32 pe32;     
      if(Process32First(hSnapshot,&pe32))
        {           
          do
           {             
                 printf("pid %d %s\n",pe32.th32ProcessID,pe32.szExeFile);         
            } while(Process32Next(hSnapshot,&pe32));       
        }        
       CloseHandle(hSnapshot);   
     }
 } 

Thanks

For these functions. It is useful to remember GetCurrentProcess. Besides GetModuleFileName which takes a handle to a module so it can only be run inside the process you want to get the information about, and it explicitly documents that if you pass in NULL for the first argument then you will get the path to the executable, the others takes a handle to a process. When a function says that it takes a handle to a process, you can then use GetCurrentProcess to get a handle that refers to the current process.

So for QueryFullProcessImageName it would be

QueryFullProcessImageName(GetCurrentProcess(), 0, exepath, &exepathlen);

This also ends up faster than tool help too.
