GETDIRECTORYDLGPARAMS

Summary

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.

Syntax

typedef struct _GETDIRECTORYDLGPARAMS 
{ 
   L_UINT uStructSize; 
   L_TCHAR  *pszDirectory; 
   L_INT nBuffSize; 
   L_TCHAR  *pszFilter; 
   L_INT nFilterIndex; 
   L_TCHAR  *pszTitle; 
   LPPOINT pptPosition; 
   LTCOMMDLGHELPCB pfnHelpCallback; 
   L_VOID  *pHelpCallBackUserData; 
} GETDIRECTORYDLGPARAMS,  * LPGETDIRECTORYDLGPARAMS; 

Members

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.

pptPosition

Ignored.

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
