The FILESASSOCIATIONDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogFile::DoModalFilesAssociation 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.
pszFormats	Pointer to a buffer containing pairs of null-terminated strings, which represent the filter(s) to be associated or de-associated and the filter pattern. The last string in the buffer must be terminated by two NULL characters.
	The first string in each pair is the display string that describes the filter (for example, "LEAD"), and the second string specifies the filter pattern (for example, "*.CMP").
	To specify multiple filter patterns for a single display string, use a semicolon to separate the patterns (for example, ".JPG;.JPEG").
	If pszFormats is NULL, the dialog box shows the default image file formats that LEADTOOLS support.
	Set this member to initialize the dialog.
	For example, this member could be set to the following:
	"LEAD (.cmp)\0.cmp\0DICOM (.dic)\0Windows Bitmap (.bmp)\0*.bmp\0\0"
pszSelectedExt	Pointer to a buffer, containing null-terminated strings that represent the filters to initially be checked and associated. The last string in the buffer must be terminated by two NULL characters. Set this member to initialize the dialog. This member can be NULL.
	For example, this member could be set to the following:
	".cmp\0.dic\0*.bmp\0\0"
pszServerAppName	Pointer to a buffer containing a null-terminated string. This represents the “Programmatic Identifier” to be associated with the selected image type(s) when successfully exiting this dialog. The dialog assumes that the server application name has already been created before calling the dialog. For more information about creating a file association programmatic identifier, refer to the Microsoft Windows Win32 SDK documentation.
uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_FILESASSOCIATION_SHOW_CONTEXTHELP	[0x00000001] Dialog should contain a context sensitive help icon.
pptPosition	Ignored.
pfnHelpCallback	Ignored.
pHelpCallBackUserData	Ignored.
