Have a look to EnumWindows [^] function. :)

I am using vs 2005.I need native c++ code to perform the same task. It'd be great if your are telling me how to implement that CALLBACK func which is used in EnumWindows() API.

[CPallini]

Implementing the callback isn't difficult. Anyway, to fullfill your requirements, maybe this example [^] is more appropriate. :)

Thanks a lot for you quick response. This exmple is for enumurating all processes.I need only Applications those are are displyed in Task Manager->Application tab.

You could use the tool help library:

#include <Tlhelp32.h>
...

HANDLE hProcessSnapshot = CreateToolhelp32Snapshot(TH32CS\_SNAPPROCESS, 0);
if (INVALID\_HANDLE\_VALUE != hProcessSnapshot)
{
	PROCESSENTRY32 processentry;
	processentry.dwSize = sizeof(PROCESSENTRY32);
	if (::Process32First(hProcessSnapshot, &processentry))
	{
		do
		{
			// do something with the info in processentry

			TRACE("%S\\n", processentry.szExeFile);
		}
		while (::Process32Next(hProcessSnapshot, &processentry));
	}
	::CloseHandle(hProcessSnapshot);
}

I got the soln.Now problem is I want to store all app names inside a container(Vector).And finally calling a function to print it.But that function is unable to print these application names correctly. #include "vector" using namespace std; wchar_t szText[256];//Holds app name //Print function void PrintText(vector<wchar_t*> apps) { for (vector<wchar_t*> ::iterator itr = apps.begin(); itr != apps.end(); ++itr) { wprintf(L"%s \n", *itr); } } vector<wchar_t*> r_apps; //Inside callback func bool callbackfn(.....) { ...... ...... ...... // if printing szText using wprintf() it is printing the app names correctly. //using vector to store all these app names r_apps.push_back (szText); } //Main func int _tmain(int argc, _TCHAR* argv[]) { ....... ....... PrintText(r_apps); return 0; } PrintText() is unable to print the app names correctly. My o/p comes like below: ?????????????????????????↕?A?↕?A?↕?↕?????????????????????????? ?????????????????????????↕?A?↕?A?↕?↕?????????????????????????? ?????????????????????????↕?A?↕?A?↕?↕?????????????????????????? ?????????????????????????↕?A?↕?A?↕?↕?????????????????????????? ?????????????????????????↕?A?↕?A?↕?↕?????????????????????????? ?????????????????????????↕?A?↕?A?↕?↕?????????????????????????? ?????????????????????????↕?A?↕?A?↕?↕?????????????????????????? // If using wprintf() above 'r_apps.push_back (szText);' statement then o/p come like belows.

I can't tell what you're doing in that code, but it looks like you're adding the same wchar_t* to the vector every time, and there's no valid string data being pointed to. If you're going to store wchar_t pointers in the vector, then you need to allocate a separate buffer for each string and copy each string's contents into the new buffers.

This[^] is helpful for you.

This program will display all the running processes but not the application names those are displayed by Task Manager->Application. Another q. is to use TRACE what header I will have to include.

[Mark Salsbery]

A search ffor "list running processes" yields lots of info. For example: this one[^]

Diagnostic Services (MFC)[^] I just used that as a test example - you'll probably need to output to someplace more useful. Mark
