Hello! I developed some keygens written in Visual Basic 6.0 BUT i believe that i have compatibilty problems when i am trying to execute the compiled exe files on computer system without the Visual Basic runtime files (.OCX etc).... Any solutions how can i avoid these type of problems?! Can i attach these #%$#% runtime files in my program code?! (I just want to have a compatible keygen written in Visual Basic on an xp system without any "x file is missing" problems...) I already know that unistalling VB and have a fresh start programming in asm is a good solution... Thank You in advance

Hi all RE Experts, I would appreciate if you can help a noob here. Ok , i have a server application(only binary code no source) that i have added additional functions-using olly .

This is one of the better asm tutorials i have found as far as explaining modes such as protected and real etc.. so if your new to asm like i am check it out it helped me out alot.The biggest pain in the *** with programming in assembly is that most of the tutorials online and alot of book's are written in dos real mode and as many of the more experienced members can tell you it's a waste of time if you want to program in asm under modern day windows.So check it out it h**p://www.drpaulcarter.com/pcasm/

Hi All, I was wondering if someone could have a look at my src and tell help figure out what I have done wrong or am missing with my plugin code. :EDIT: the dialog boxes don't appear correctly, and the patch just crashes olly when he tries to load a file. here is the src. It is in masm and winasm studio. It is a plugin to patch GetSystemTime, to hide olly from various techniques that read it and do some other things, like int3 or checking how long some code takes to execute. thx

Masm: Resource Compiler Error Rc2170
by Ufo-Pu55y- 3 replies
- 7.1k views
Does anybody have experience in saving GFXs in the right format ? I mean in the format, in which the compiler needs it ? When I try to throw in own icon- or tga-gfxs, it always gives me this error: Error RC2170: bitmap file *** is not in 3.00 format When I use other files (not made by me) it works fine. For example in Photoshop, how do I save a file in this "3.00 format" ? Even with other tools... for example after using a BMP-To-Icon-Converter the compiler says that it's not "3.00 format"... :/ Are there any ***-To-3.00 format-Conversion-Tools ???

Patches

hi, i want to create a patch for a general program, but i'm not sure how to do it. i thought to this solution: 1 - modify the exe file; 2 - compare the normal file with the modified one to find the different bytes; 3 - put into an array the position of the bytes in the code and their new values; 4 - tell the program to open the normal exe file, find the bytes and modify them with the new values 5 - close the exe file. is this the right way? and do you know other solutions? and of course, sorry if my english is cruel
