Assuming this is the defaut Windows API listbox..

Step 1: Find a handle to the window containing the list box. [link]
Step 2: Allocate enough space to hold the strings. eg.

C++ Syntax (Toggle Plain Text)

int count = (int) SendMessage( listbox, LB_GETCOUNT, 0, 0 );
std::string *items = new string[count];

int count = (int) SendMessage( listbox, LB_GETCOUNT, 0, 0 ); std::string *items = new string[count];

Step 3: Retrieve those values. eg.

C++ Syntax (Toggle Plain Text)

for (int i = 0; i < count; ++i) {
  int itemLength = SendMessage( listbox, LB_GETTEXTLEN, i, 0 );
  char *temp = new char[itemLength];
 
  SendMessage( listbox, LB_GETTEXT, i, (LPARAM)&temp );
  items[i] = temp;
 
  delete[] temp;
}

for (int i = 0; i < count; ++i) { int itemLength = SendMessage( listbox, LB_GETTEXTLEN, i, 0 ); char *temp = new char[itemLength]; SendMessage( listbox, LB_GETTEXT, i, (LPARAM)&temp ); items[i] = temp; delete[] temp; }

I haven't tested this code, but it should work if you apply it right. Hope this helps.

thanks William, for your response.
Can you pls do me a favor to write a tiny app to read those values. With an interface like, specifying the window handle by some drag/drop thing and then read the list box values, etc.

I am very new to C++ programming and got this as a task :-s

Look forward to your response...

That's too much to ask for.

If you're very new to programming, you shouldn't have been set a task like this. I wont do it for you, but what I will do is lead you in the right direction. Start by familiarizing yourself with basic C++, then follow this Win32 API tutorial [link]
There's plenty in there to get you started, after all, that's exactly how I learnt it.

Remember, we aren't here to write code for you.

It won't fork for od listbox

What? Once again, not helping.
Also, I said

Well, thanks Williams for guiding me to the tutorial.

Actually I am C# developer and may be I can convert your provided code .net to have it work for me.

OK... this program worked with no errors... But now I want to print the results and "cout << items[i]" is not working..

Could anyone please tell me how to print "std::string" type strings?
