SAS-L Digest - 9 Jun 2001 to 10 Jun 2001 (#2001-723)

Thanks for translating Larry's VB into SAS Richard. It is what was needed. I'll browse his site at a later time for any other interesting ideas he has published.

I browsed M$ and found the API definitions, and have tracked down the AppendMenu and InsertMenuItem APIs which I will tuck away against the need to restore the functionality while the application is running.

The application becomes the SAS session, since it is initiated from an initstmt in the config, and the SAS session is closed when the AF application closes.

If you have a maximised AWS, then the control buttons merge and the Window control is subsumed by the SAS session control. Consequently, unless you 'zoom off' the AF window, clicking the 'X' button will cause SAS to initiate the equivalent of an Endsas command, and not initiate the TERM block of the application. You intimated as much in your later email.

At least now I can stop my user from leaving locks in place on parts of the application.

David: Here is sample moduleN code to remove the SAS system menu Close, which disables the X icon. As long as you can prevent the user from issuing an endsas command you should be ok for always running the frame application TERM

*put this in autoexec; *if you do equivalent in the frame INIT: it works but the SAS window is not redrawn showing inactive state of X (greyed X);


data _null_;


input ; put _infile_; cards4;

routine FindWindowA module = user32 minarg = 2 maxarg = 2 stackpop = called returns = ulong ; arg 1 char input byaddr format=$cstr200.; * LPCTSTR lpClassName; arg 2 char input byaddr format=$cstr200.; * LPCTSTR lpWindowName;

ROUTINE GetSystemMenu module = user32 minarg = 2 maxarg = 2 stackpop = called returns = long ; arg 1 num input byvalue format=ib4.; * HWND hwnd; arg 2 num input byvalue format=ib4.; * BOOL bRevert;

ROUTINE RemoveMenu module = user32 minarg = 3 maxarg = 3 stackpop = called returns = long ; arg 1 num input byvalue format=pib4.; * HMENU hMenu; arg 2 num input byvalue format=ib4.; * UINT uPosition; arg 3 num input byvalue format=ib4.; * UINT uFlags; ;;;;

data _null_; WinClass = 'SAS aws'; WinTitle = 'SAS'; hWndSas = modulen ('FindWindowA', WinClass, WinTitle); hMenuSas = modulen ('GetSystemMenu', hWndSas, 0);

* assume the standard window menu, * (that drop down menu shown when upper left icon clicked or * when icon in task bar right clicked) * is Restore:Move:Size:Minimize:Maximize:Separator:Close *;

mf_bypos = 0400X;

rc = modulen ('RemoveMenu', hMenuSas, 6, mf_bypos); * remove Close; rc = modulen ('RemoveMenu', hMenuSas, 5, mf_bypos); * remove Separator; run;
