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.

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?↕?↕??????????????????????????

// 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 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.

A search ffor "list running processes" yields lots of info.

For example: this one[^]

I just used that as a test example - you'll probably need to output
to someplace more useful.

  }

Plz help me

What has to do your code with duplicate values?
What is b?

MsmVc28-Sep-08 19:35

28-Sep-08 19:35

I have no idea how to remove duplicate values?

B is a String type variale which have some values.

Plz help me

CPallini28-Sep-08 21:55

28-Sep-08 21:55

You know an edit box can have just 1 value at time, hence how can be duplicate values?
Smile | :)

MsmVc28-Sep-08 23:28

28-Sep-08 23:28

Different Edit box have same value.Like that

Edit a1="a"
Edit a2="a"

Just i don't want to store a2="a". So how can i remove sir

CPallini28-Sep-08 23:38

28-Sep-08 23:38

Well, it is not difficult: compare the two strings, if they're equal prompt an error message to the user. What is your trouble about?
Smile | :)

You can use of CString:Find and if result is ok you can use of your code.
