OPENFILENAME initialization

[Donotalo]

look at the following code:

char filepath[1024] = {0};
OPENFILENAME ofn;
...
memset(&ofn, 0, sizeof(OPENFILENAME));
ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hwndOwner = hDlg;
ofn.lpstrFile = filepath;
ofn.nMaxFile = sizeof(filepath);
ofn.lpstrTitle = "Choose A File";
ofn.Flags = OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST;
if (GetOpenFileName(&ofn)) {
...
}

i want that the first searching folder be the folder where the program resides. i thought that the above code would do that. but it starts searching from My Documents. what else do i need to start searching from current folder? thanks in advnace.
