    softice and visual basic

    Good morning all
    I'm having difficulties debugging a visual basic program with softice
    I have win xp sp3 installed in vmware and of course softice installed in the virtual machine. it works to set breakpoints on kernel32 functions, but i need to set it to work on msvbvm60.dll functions, in specific rtcMsgBox.

    In c:\windows\system32\drivers\winice.dat i have the following:

    ; WINICE.DAT
    ; (SystemRoot\System32\Drivers\WINICE.DAT)
    ; for use with SoftICE for Windows NT (versions 3.0 and greater)
    ;
    ; ***** Examples of export symbols that can be included *****
    ; Change the path to the appropriate drive and directory
    ; EXP=\SystemRoot\System32\hal.dll
    ; EXP=\SystemRoot\System32\ntoskrnl.exe
    ; EXP=\SystemRoot\System32\ntdll.dll
    ; EXP=\SystemRoot\System32\kernel32.dll
    ; EXP=\SystemRoot\System32\user32.dll
    ; EXP=\SystemRoot\System32\csrsrv.dll
    ; EXP=\SystemRoot\System32\basesrv.dll
    ; EXP=\SystemRoot\System32\winsrv.dll

    I added an extraline without the semicolon
    EXP=\SystemRoot\System32\msvbvm60.dll
    And removed the semicolons from the others.

    But still i'm not able to set a bpx on msvbvm60!rtcMsgBox
    I get a "no ldt" from softice

    *i start softice manually from "ntice.bat"

    If somebody could guide me step by step to be able to put a bpx on rtcmsgbox i'll be in his debt
    I promise that I have read the FAQ and tried to use the Search to answer my question.

    SoftICE is very outdated. Try http://ollydbg.de/ instead.

    My *ICE is a bit hazy, but you could first try running:

    EXP MSVBVM60.rtcMs* to see if it has *indeed* picked up on the exported functions.

    THEN, before you put a bpx, make sure you are in the right CONTEXT (same command).
