Also, notice that it provides HWND of the static control that will display the name of the folder, so this might be useful to you ( this parameter can be NULL if you do not wish to use static control ).ĭirectory names have square brackets like this. This function always adds file names as well to the list box, so you will need to find a way to filter them on your own. You can use simple list box to do that, or you can use DlgDirList function to do that-all you need to do is to pass DDL_DIRECTORY as the last parameter. I'm creating a Listbox with a list of foders.I want to show the name of the folder the user double click.

In other words here, the main problem you had, in my view, was that you had not fully identified your problem. Doing that makes it much easier for you to narrow the problem down and so find the solution. So, irrespective of what fixes the problem, the best advice I can give you is to try learn how to diagnose and describe a problem better. Confirming facts like that is a basic part of debugging and is something that you must learn to do. In which case that's the first thing to sort out. But the other answers suggest that your code may not execute. Note: I was assuming that your code does actually execute. Use LB_GETTEXTLEN to find out how large a buffer you need. Again, the documentation makes this clear. So change the declaration of Temp like so: wchar_t Temp Īnother possible problem is that you are expected to supply a buffer of sufficient length for the string, and the null-terminator. And so are expected to supply a buffer of wide characters. Now, the most likely cause of problems is that you are compiling a Unicode project. Again, you must consult the documentation carefully. You should also capture the return value and check for errors. You could write it like this: SendMessage(hList, LB_GETTEXT, SelIndex, (LPARAM)Temp) Next up is: SendMessage(hList, LB_GETTEXT, (WPARAM)(int)(SelIndex), (LPARAM)(LPCTSTR)(Temp)) The documentation tells you that in the event of error, LB_ERR is returned. You assign to SelIndex but don't check for errors. For instance: SelIndex = SendMessage(hList, LB_GETCURSEL, 0, 0L) First of all you seem to be doing a lot more casting than you need to. Len = SendMessage(hList, LB_GETTEXT, (WPARAM)(int)(SelIndex), (LPARAM)(LPCTSTR)(Temp)) ///////////////Combining the answers of some users, a script that works is like follows: switch (message) But I get nothing, what am I doing wrong? With the first one I should get the line of the list box the user have clicked, and with the second one I should store into Temp the text that appears in the clicked line. SendMessage(hList, LB_GETTEXT, (WPARAM)(int)(SelIndex), (LPARAM)(LPCTSTR)(Temp))

SelIndex = SendMessage(hList, LB_GETCURSEL, 0, 0L) LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) I want to show the name of the folder the user double click. I'm creating a Listbox with a list of foders.
