IntControl (49, p1, p2, 0, 0)
Adds system menus to WIL popup windows.
p1 specifies which popup windows will have system menus:
p1 Meaning
-1 Don't change (return current setting)
0 No system menus (default).
1 Dialog boxes (created with "Dialog" or the WIL Dialog Editor). Note: If using dialog callback procedure use DialogProcOption code 1002 instead.
2 Item listboxes (e.g., created with"AskItemList", "AskFileText" or related functions).
3 Both Dialog boxes (1) and Item list boxes (2).
p2 Meaning
specifies the value that a dialog box (created using the Dialog function) will return if the user closes the dialog without pressing one of the pushbuttons in the dialog (e.g., by pressing <Alt-F4>, or by clicking on the "Close" icon in the title bar). If a dialog returns 0, processing will be transferred to the label in the script marked ":Cancel" (if any).
IntControl 49 allows certain types of WIL popup windows to have system menus, (the drop down menu of minimize/maximize options accessed via the small icon or box to the left side of a windows title bar).
Returns previous setting for p1.
