Run Error
hi,
i have this strange error when trying to run my project.
"Project C:\Workspace\test.exe faulted with message: 'access violation at 0x40015e61: write of address 0x00040f70'.
When I delete the executables, then the error is gone. But after i run the program for several times, the error comes back.
I don't know which part of my code raise this error. It happens at this line "Application.Run"
Please help :(
I attach my cpu windows.
Regards,
Reynaldi

If it's random... Do you have threads running, timers running, database querying ???
Threads might cause AV when accessing non thread safe vars.
Timers might be accessing variables not initialised.
Database querying might query databases with connection problems.
Running it from Delphi. Did you use the "stop on Delphi exceptions" with the integrated debugger.
When the AV appears you can sometimes call the stack with Ctrl-F3 to see what routing caused the AV.

Hi, i just got that faulted error again . but it's not av this time. I use madExcept 3 but it couldn't catch the exception. I run for several times the error keep coming, until one time the error just gone. I didn't change anything, all i do is press F9.
Could this be a virus in my comp?

--------------------------
i do have timers, but i've checked and i didnt find anything wrong with it.
I couldn't press Ctrl-F3 and yes i use "stop on Delphi exceptions".
As soon as i compile and run, delphi showed "Debugger Fault Notification" window and the CPU window.
I also sometimes get Invalid pointer exception when i stop the application.
This is so strange cause i never got this error since last week.
i only did minor modification.

please also give a try with eurekalog (www.eurekalog.com), ciuly mentioned it as well, it might give you more information.

Hi guys, i installed eurekalog and error just disappeared. I have no idea what happened.
Anyways, thank you all for your comments. I'll post another question if error comes again (hopefully not) :)

I'm still waiting the error to come. it's happen at random time.
I use many bpl for my application. do i need to set different image base to each package? could that be the problem?
