Q. I am using the OFN_ALLOWMULTISELECT option of the TOpenSaveDialog class to be able to select
multiple files in an Open Dialog Box (BC++4.52).
It
works for selecting up to 4 files, but when more files are selected, the program does nothing!
Can anybody tell how to select more files (say 50?)
A. You have to allocate and assign a (large enough) memory block to TData::FileName.
Assign the length of this block to TData::MaxPath.
Don't
forget to (first) delete the (default) memory block assigned to TData::FileName when this
structure is created;
Here's a code snippet:
TOpenSaveDialog::TData FileData; //data structure for TFileOpenDialog delete [] FileData.FileName; FileData.FileName = new char[50*MAXPATH]; //MAXPATH is defined in a of BC++ header file *FileData.FileName = 0; FileData.MaxPath = 50 * MAXPATH; FileData.Flags = OFN_ALLOWMULTISELECT; TFileOpenDialog (parentWindow, FileData, 0, "A title") OpenDialog;
