Black Screen of Death.
Posted: Fri Sep 08, 2017 02:44 PM

I have a fairly large app that sometimes the area of the MDI Frame turns black. Is this some sort of a resource leak in my app, any suggestions on what to check for, or how to remedy.

I presume this happens randomly ... I would put a few well placed oWndMdi:Refresh() and perhaps accompanied by a SysReFresh() after coming out of some of your large ( add\edit ) modules .. after you close your tables ... especially if you are closing ADO tables .. and if they are Ado tables .. make sure you destroy the oRs Object .... oRs := nil ( even if oRs is a Local variable ) .. then oWndMdi:ReFresh(),SysReFresh()

No to the Gradiant in the background.
Rick, thanks sounds very reasonable. It does use ADO everywhere.

How do you make sure they are disposed of properly?

Just launch my program, and then exit , and I get:

CheckRes.Txt file...
09/09/17 11:23:08: C:\Datafile\tmsbcc\tmsbcc.exe -- FONT,1846159188,TMDIFRAME:GETFONT(3122)->TMDICLIENT:GETFONT(3099)->TMDICLIENT:NEW(147)->TMDIFRAME:NEW(178)->MAIN(106)

09/09/17 11:23:08: C:\Datafile\tmsbcc\tmsbcc.exe -- BMP,-1476060091,TMDIFRAME:HANDLEEVENT(0)->_FWH(3602)->WINRUN(0)->TMDIFRAME:ACTIVATE(1020)->MAIN(119)

09/09/17 11:23:08: C:\Datafile\tmsbcc\tmsbcc.exe -- ====================================================================================================
End of CheckRes.txt file...

How do I get rid of these?

Byron ...

Don't worry about those as FWH will clean them :-)

Have you tried monitoring the GDI count on the Details tab of Windows (10) task manager?

On my Windows 10 Task Manager I don't see GDI Count, where would I find it.

On Details Tab:
Name
PID
Status
User name
CPU
Memory (private working set)
Description

Or is it one of the rows of the grid?

Thanks,

Byron:

You may need to right click on one of the column headings to show a list of all column headings and then check the GDI column so it's visible.

As you open and close various windows/dialogs in your app you can watch the GDI count go up/down. As you close a dialog or window the GDI count should return to the value it was before you opened it or more specifically, repeated calls to the same window/dialog/report, etc. should not cause the GDI count to continue increasing.

Once I see this number, what action do I take based on what value?

My customer is really getting a little pissy about this happening.

Can you reproduce this behavior on your machine or on other machines ... If not, I would ask your Customer to look at the offending machine(s) device manager and see what display adapter is in those machine(s).

I bet you will find this is a local machine problem and a cranky video driver.
