- Heap Alert 1.1 is (yet another) Windows snooper. It informs
- you about GDI objects in use. I wrote HA as a debugging tool;
- my app was using up system resources every time I ran it,
- and I had no clue what was not being freed.
-
- Source is included with 1.1. You'll see that there is really
- nothing to this program -- it is very simple.
-
- Version 1.1 only runs under Windows 3.1 commercial. It will
- not run under 3.0 or any of the betas of 3.1. These betas
- had bogus versions of toolhelp.dll that lied. You will get
- very funny results if you run on anything less than 3.1
- commercial.
-
- You'll need vbrun100.dll (available on CICA), as HA is written
- in Visual Basic.
-
- HA tells you about USER, GDI, fonts, bitmaps, DCs, brushes,
- regions, pens, and palettes.
-
- Because of a bug in Windows 3.1 HA no longer shows the number
- of metafiles in use. The metafile count is merged into the
- "Other" category.
-
- You can tell HA to automatically update every four seconds
- or update only when you press "sample".
-
- Saved me hours; hope it does the same for you.
-
- I ran HA, then started/killed each of these apps to see what
- they left behind. Very interesting (scary):
-
- Object Vision 2.0: 1 bitmap
- Micrographix Designer 3.02: 1 brush
- PowerPoint: 3 bitmaps, 3 brushes, 6 'other'
- QuickC/Win: 1 palette
- ToolBook 1.5: 1 bitmap
- CorelDraw 2.0: None
- WordPerfect/Win: 1 bitmap, 4 'other'
-
- Excel 3.0 and Word for Windows 1.1a were OK. If you try
- any other apps, send me mail to let me know how they fared!
