fatal crash on win98 & winMe, Need help.

[haritadala]

Hello all I've an application which is working well on win2000 & winXP. But when I ran the same application in win98 & winMe, it's leading to fatal crash and giving me blue screen. In the case of fatal crash, how can we detect to which part of the application is causing it? I'm not able to debug this problem on win98 and winMe. If anyone know abt any tools or techniques which can help me in debugging the problem, pls help me. Many thanks for your help. Hari.

Hello David Thanks for the reply. I'm not using or assuming something that's not on NT machines. My application is taking to devices connected to usb port. I'm using the driver supplied by third party vendor(this driver works on all windows machines, according to vendor). I'm able to send/receive data even on win98/winMe. But when I try to disconnect I'm experiencing fatal crash. Any ideas as on how to debug this problem will be very much appreciated. Many thanks for your help. Hari.

It sounds like you need to contact the vender of the driver. If all else fails try to find a memory validator or crash protect program, that can generate a report, even if the code is not available. Once upon a time, I kept rejecting the release of a program based on the reports generated by Bounds Checker, since our sister would not release the code to me in order to find the multple problems. Eventualy, they just turned the whole project over to me and it took months to find and fix all the problems. INTP

How is it that you are unable to debug this on 98/ME? Are you using .net/2003? If so, look into the remote debugging features of it, you should be able to debug that way.... Or is the blue-screen coming before any exceptions are trapped? :) -p ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Peter Weyzen Staff Engineer [Santa Cruz Networks](http://www.santacruznetworks.com)

Hello all Thanks for the replies. I'm not using .Net/2003. I'm getting blue screen before any exceptions are trapped. I'm getting the following error fatal error 0E at 0028:C0003E8C I looked at microsoft knowledge base for these error but couldn't find the solution :( Any ideas? Thanks for the help. Hari.

I think that there are many causes -- what exactly does your program do? You can check out this site (click here)[^]-- for possible answers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Peter Weyzen Staff Engineer [Santa Cruz Networks](http://www.santacruznetworks.com)
