Hey all, Something else than those C++ and x86 asm programming stuff topics. Let's hope someone knows soemthing. I've been attempting to code an interrupt driven usart connection between an AVR chip board and the PC. (the PC is sending the data) However it seems that when an byte is recieved it keeps giving interrupts even when the buffer is read. (which should stop that according to the datasheet) Interrupt code which is properly triggered when recieving a byte but just keeps interrruptingand spamming my terminal: Serial_Recieve: ;store incoming bytes in r24,UDR out UDR, r24 reti Am I missing something here. Afaik I am initing the serial connecti…

right, so yesterday night i had a native vsc++ 2008 project display a dialogbox using the DialogBox(...) functon. worked perfectly fine. i then went to bed, and when i got up this morning, the exact same DialogBox call would just return -1 and fail. I then did some further testing: 1) Creating a dialogbox with a list view on it always fails 2) creating a dialogbox with NO list view on it always succeeds. sometimes the dialog will get display correctly, sometimes the form-background is missing and some dialog items are floating around freely.it always takes up 100% cpu power. 3) creating a new,clean project with a dialog but no list view, it works in the beginning, but aft…

hi, so i have been messing with native GUI programming in msvs2008 recently and lots and lots of problems & questions arose... Most of them were exterminated by a quick google search. This one is a little persistent, though: I have a class, myclass. The user can create multiple instances of that class. Every class instance has its own instance of a dialog box, which can be displayed at the same time. How can i now link a class instance to a dialog box? ie, if the dialog boxes CALLBACK routine is called, how can i know which class instances dialog box send the message? deep0

hi all, this little problem is killing me: char data[256]; mystruct* mystructptr; //copy some stuff into the data buffer int the buffer "data",there are 12 junk bytes, but then there is a mystruct struct. i need to point to that struct... way #1: mystructptr = (mystruct*)(data+12); this works just fine, mystructptr points to the address of "data" + 12. this, however, doesnt work: mystructptr = (mystructptr*)data; mystructptr = (mystruct*)(mystructptr + 12); or mystructptr = (mystructptr + 12) or mystructptr += 12; the data buffer gets increased by ~0x400 bytes, not 12... i really cant see why #2 wouldnt work.

Hi. I wanted to ask a small favor if anyone has some spare time. I guess most of you could do it in 15min or so. I am working on a project but I don't want bla bla bla about that and I found myself in need of C# Keygen and also solution. While I may be one of best ARM Assembly guys around, C# is really not my thing. So, I was thinking something in these lines: 1. Make a "standard" C# keygen 2. Put a small "twist" in it (if possible). By that I mean a small obstacle. Anything you can think of. 3. Make a solution. 4. PM me the stuff. If anyone could do it I would be very grateful and if you need something from ARM world, just let me know and it is done. I hope you understoo…

exe/dll

Hi, I´m trying to create an .exe file, which can be used as a dll file at the same time. Take, for example, this piece of code: #include <Windows.h>BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { MessageBoxA(0,"dll","dll",0); } int main() { MessageBoxA(0,"exe","exe",0); } Just executing it like any other exe will run int main(). Now, the idea is that when this .exe file is loaded via LoadLibrary DllMain is called as if it was a dll. Is this actually possible? Or is there any other way the exe gets notified when it is LoadLibrary loaded? deep

This is an old Project to create a debugger core using VB.NET 2008 ofc it's not the best choice to code a debugger not because it's weak ! but because VB.NET doesn't support unsafe code like C# so you will have to add extra lines of code to pass structures between managed and native code. this Project requires some knowledge of Marshaling techniques, i.e passing data structures between native and managed code. I hope someone will find it useful all comments are welcome ofc P.S : It won't work on XP because I used a new API which is only supported by Vista and later OS, this API is "GetFinalPathNameByHandleW" ofc it can be wrapped using some other techniques to …

calloc question

I've got question about calloc. From what i know calloc uses two paramas - size of element & number of elements. It allocates memory of size of elements * number of elements and returns a pointer to that memory in eax. Memory allocated is filled with 0. My question is what is in four bytes before the pointer? I.e.: push size of elements push number of elements call calloc ;now eax holds pointer to mem mov edx,[eax-4] - what will be in edx Is it totally random or is it somehow determined?

custom string class: memory leak

February 11, 2011 by deepzero

hi guys, i was trying to implement a custom string class for practicing purposes, but i hit a problem regarding memory leaks... to be more precise, the problem is the substring-method: substr(int start, int length); to be used like this: mystring a = "deepzero"; mystring b = a.substr(4,4);//b == "zero" or MessageBox(0,a.subtr(4,4),"test",0); the problem is: when i create the substring, where do i store it? When i allocate space on the heap, it wont be freed anymore... So i figured i`d have .substr() return a mystring object (containing the substring): mystring mystring::substr(int start,int len) { //ptrtostr == pointer to the actual char-array which stores t…

Yohoo guys, I'm proud to present my new decryptor: PELOCKnt decryptor v1.0. This one is based on my previous BJFnt decryptor, because PELOCKnt is an update release of BJFnt. It currently has support for PELOCKnt v2.01, v2.03 and v2.04. (I haven't actually PELOCKnt v2.02) If someone have a copy of PELOCKnt v2.02, don't hesitate to send me it... I will include support in my decrypter... As usual, source code in masm and cryptors are also included for interested ones... Any comments, bug reports or others are welcome... See you soon ...
