From: Frisbee� on 10 Apr 2010 09:30 As opposed to an expected one? Losing what's left of my hair over this one... My accounting app written in VB6 SP6 is crashing. But only on one machine at a client's site. What's really strange is that my app was running until some arbitrary update (I update several times a week on average) and he's not been able to run any updates past a specific one. Yet those same updates run just fine on all the other computers on the network on-site. The only one that fails with "Unexpected Error" is the one running terminal services (or whatever it's called now) under Windows 2003. They have a remote site accessing the package, been running fine for months, now suddenly won't work on anything past a certain release. Of course, a custom change they needed is on one of the later releases. Where its failing is the main module load, which has not been modified for at least a year. Nevertheless, I have placed debugging code (high-tech msgboxes!) all over the place in the form_Initialize event, then in the form_load event. He gets all the messages in form_initialize, then the dreaded "Unexpected Error" message. Thinking it must be some event in between initialize and load, I added the same debugging messages to all events that had code - same result. Then I added debugging messages to all events, period - same result. Then I ran a trace on my own to see what other events might be occurring between initialize and load, and at least on my machine, no other events happen between those two. I am sure it almost has to be terminal services, since nobody else is getting this error anywhere, and there are hundreds of other users. Please, I"m down to about four or five hairs on my head! Please help me save the follicles! Bill "Frisbee" Hileman Newly-designated Owner of Hamelin Software http://www.hamelinsoftware.com

Nice catch. It isn't vaAccelerator, but it is Infragistics Outlook Bar and Explorer controls. Problem is, I have not altered -anything- on that main form for at least a year, and the program -was- running just fine up until a couple of week ago. I did suspect it was a form_resize event, since I do indeed alter the size of the outlook bar, explorer, and two command buttons based on previous settings stored in the registry, but the resize event is apparently not fired until the form is shown, and it never even enters the form_load event on that machine.

Controls are loaded between Form_Initialize and Form_Load.

Are they in the expected range? Maybe they cause the crash. Does your program check those values or just pass them to the controls? Helmut. |
