I made a program by visual basic that requires you to select some pictures in order to enter
If you select the wrong pictures it gives you a message box which says "wrong selection"
If you succeed it does nothing but saying "seccess"
Although this is my own program, I can't crack it because I don't know what API function to break point upon
I just want to know where exactly to break point
I want to crack it using only softice or wdasm not a visual basic decompiler
The program is included with this message
Note: The right selection is 1 3 2
Any help will be appreciated
Thanks

the breakpoint address you should look at 0x404CC6. this is where the conditional jump is and jumps if incorrect sequence.

to patch - nop out the 6 bytes of the jump or patch the jump location.

1)
je 0x404DC4 ==> nop, nop, nop, nop, nop, nop
2)
je 0x404DC4 ==> jmps 0x404CCC

You should be able to bpx on __vbaFreeVar or __vbaVarDup on should get you into the code before the messagebox, the other after.
