Hi,
I am trying to setup the WinDbg debugger to debug the printer driver. I
followed the steps below-
1. Open MSPaint application.
2. In WinDbg, Select [Attach to process] menu option. Select MSPaint
process.
3. Set the symbol path to C:\Windows\Symbols(where I installed the symbols)
4. Set the source path.
5. Set the image file path.(where my driver is kept).

After doing the steps above when I try to set a breakpoint in the code it
gives an error message saying "code not found, breakpoint not set". The
following errors are also shown in the command window of WinDbg-
.....................*** ERROR: Symbol file could not be found. Defaulted to
export symbols for C:\WINDOWS\System32\ntdll.dll -

*** ERROR: Symbol file could not be found. Defaulted to export symbols for

If anybody have any idea what is wrong and why I am getting above errors,
please let me know.

verify that the symbols are correct. If you are running SP1, do you have
any security updates? Verify that the symbol file has a time/date stamp
close to the binary date.

I like to place symbols per binary type in their own directories

_NT_SYMBOL_PATH=g:\symbols

tree g:\symbols
Folder PATH listing for volume Local Disk
Volume serial number is 0006EE50 20AF:0E0F
G:\SYMBOLS

????ax
????cnv
????com
????cpl

????exe

You should be able to set a breakpoint on your binary without any of the
system binary symbols. You driver file will not load until you invoke File
Print in mspaint and select the printer which uses your driver.

not sure how windbg works but set a load bp for your module. Here is an
example for ps5ui.dll

0:005> sxe ld ps5ui.dll
0:005> g
ModLoad: 73070000 73097000 C:\WINDOWS\system32\WINSPOOL.DRV

Hi Nitin,

From your mail, looks like you are dubugging the USER mode
(XP) printer driver.

I feel it is easy to use user mode debugger like Visual
studio IDE.
