Hi guru's,
By connecting a certain kind of printer my program crashes and gives a General Application error message with 0007:BC22.
Normally a crash address looks like this: 'The instruction at "0x004011a1" referenced memory at "0x00000000". The memory could not be "Written".'
Can someone please tell me how to find 0007:BC22 in the map file? I understand you do not have the map file, but please tell me the way to deal with this in general.
Thanks!
Hi,
"0007:BC22" looks like arcan 16 bit pointer with segment and offset.
To get help you should tell us some more:
- OS version
- compiler, linker and/or environment version of "your program"
- A short description of: Why can't you debug "your program" to know the bad code?
I assume that the driver for this certain printer raises the exception. See the web site of the vendor of this printer - it is almost not possible that you are the only one person in the world getting this error (except it is produced by "your program").
With friendly regards

Thanks for your reaction ProgramArtist. The OS version my program is compiled with is Windows 95 using Visual C++ 1.52 (really old, i know but it is still out there).
The problem with the printer occurs both on a windows 98 and Windows XP machine. The problem does not occur with a different printer.
Opening the .exe file in Visual C++ only gives me the resources and not the option to start or debug the executable. I can not get this to work. Perhaps there is a way to jump to the address mentioned in the error message?
Hallo again,
I really did expect that you would answer in that way.
You are trying to find/recover an error in an executable file.
That means:
- You did post your question in the wrong forum (since this forum is about VC++).
- Finding a bug in an executable has nothing 2 do with VC++ issues.
You tried to use MSVC as a debugger environment. Generally speaking this is possible but it is not the right approach exept you are very, very familiar with hardware programming and assembler/machine code. The debugger cannot recompile to C++. In the best case it can tell you which assembler command (maybe a MOV on a certain register of the CPU or a call to a function in your printers driver) causes the problem. You won't be able to locate the cause (reason) of the crash in that way.
Please try the following things:
- Download the newest available driver package for the printer.
- Search for FAQ's on the manufacturers web site.
- Search the internet for other people having the same problem (include as many information as possible: Printer manufacturer, type, version, driver's version, OS version, ...)
- Write an email with your problem to the support of the manufacturer.
I do not think that C++ will help you in this case...
With regards
