More erratic behaviour on new PC
Posted on 2001-08-16
I recently transferred one of my VB6 projects to a new PC which I built myself. The relevant hardware
comprises Gigabyte 7ZXR motherboard, 256k PC133 SDRAM, Athlon 1.2Ghz CPU, Matrox G450 Dual Head Video.
I have not had problems with other programs, and the project was fine on a previous Athlon 600Mhz system and has been retested on an AMD k6-500 system.
(OS=Windows 98SE in all cases). Minimal other programmes installed.)
The project is in VB6, and it uses VideoSoft VSOCX6.OCX control to provide a Tabbed Dialogue facility and it also uses vsElastic and vsElastic Light controls.
Other additional controls used are COMDLG32.OCX and RICHTX32.OCX
When testing in the IDE, and compiled I have noticed several oddities. Main ones are -
a) a version compiled on an earlier PC (600mhz) exhibits severe screen distortions when run on this new PC.
b) Running unmodified code in IDE on new machine - similar problems.
c) Compiled project exhibits similar distortions.
d) Removing vsElasticLight and most vsElastics reduces the problem in the IDE. Compiled versions OK.
The distortions are -
a) when vsElasticLight is used - problem b) plus some labels grossly enlarged.
b) vsIndexTab and vsElastics on the tabs extend below the window as designed.
c) Windows change size - in original project 7200 x 9495 - alter to say 7170 by 9390.
I have tried interchanging the video card/drivers between the Athlon 1200 and K6-500 - this had no effect.
Has anyone any pointers please?
