open explorer to dir when user double clicks

hey..i've written a program that searches non-executable files for a certain string or strings and then outputs which file(s) contain these strings to a listbox. what i'd like to do now is to allow the user to double click on an item and have that open up an explorer window to the folder that contains the file that has been found.
any ideas on how to do this?

or even, how could i add a horizontal scrollbar to the listbox? i've tried adding WS_HSCROLL but that didn't do it.

thanks

You can use the Explorer.exe /select command line syntax. Given a file, this command will open the containing folder and select the file. This is what Firefox does when you click on 'Open Containing Folder' in the download manager. Here is an example:

Code:

---

#include <windows.h>

int main(void)
{
        STARTUPINFO        si = { sizeof(STARTUPINFO) };
        PROCESS_INFORMATION pi = { 0 };

        CreateProcess(NULL, TEXT("Explorer.exe /select,C:\\Windows\\Win.ini"), NULL,
                      NULL, FALSE, 0, NULL, NULL, &si, &pi);

        CloseHandle(pi.hThread);
        CloseHandle(pi.hProcess);

        return 0;
}

mm...so with LBS_NOTIFY, is it possible to distinguish between a single and double click? because i dont want anything to happen if the user simply clicks on an item. but if a double click occurs, i want the process to execute.?

thanks :]



HAH....i hate it when this happens.
yes, LBN_DBLCLK
sigh.. lol

one more question....can i create a tooltip like thing so that when the user mouses over an item and see the full path before they double click it?

If you use a list-view control with the LVS_EX_LABELTIP extended style, tooltips are automatic. The older listbox does not have built-in tool tips and would require you to manually implement them using subclassing. I'm sure there are implementations out there.
