The GETDIRECTORYDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogFile::DoModalGetDirectory function. After the user closes the dialog box, this structure is updated with information about the user's selections.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
pszDirectory	Character string containing the directory name. Set this to initialize the dialog to open a particular directory. This will be filled with the user's directory selection.
nBuffSize	Size of the pszDirectory buffer. This should be at least L_MAXPATH bytes.
pszFilter	Character string containing filter string pairs. The last string must be terminated by two NULL characters. The first string in each pair is the display string and describes the filter (ex. "LEAD"). The second string in each pair is the filter pattern (ex. ".CMP"). Use a ";" between patterns to specify multiple filter patterns (ex. ".CMP;.JPEG;.JPG"). This is the same as would be used in the Microsoft SDK structure OPENFILENAMEW. (If you pass NULL, the file type combo box will disappear in the dialog).
nFilterIndex	An integer variable to be updated with the filter index that the user has selected in the dialog box. The first filter has an index of 1.
pszTitle	Character sting containing the title for the dialog box.
pfnHelpCallback	Ignored.
pHelpCallBackUserData	Ignored.
