Hi All...

I'm developing an ActiveX control in ATL. It has a property called "FileName". I would like to bring up the file open dialog box when the user clicks that "FileName" property in VB. I mean when the user clicks the "..." button.

Pls help me!!!

In your handler for "..." open the file dialog

TCHAR filename [ MAX_PATH ];
filename[0] = 0;

OPENFILENAME fn;
ZeroMemory(&fn, sizeof fn);
fn.lStructSize = sizeof(fn); // for Win 2000
fn.lStructSize = OPENFILENAME_SIZE_VERSION_400 ; // for Win 9x, NT
fn.lpstrFilter = _T("Text Files\0*.txt\0\0");
fn.lpstrFile = filename;
fn.Flags = OFN_FILEMUSTEXIST | OFN_NOCHANGEDIR;

if(GetOpenFileName(&fn))
{
   // filename  now has file selected by user.
}

hope this helps
