Programming and Coding

hi, for quiet some time i am occupied by this little assignment: my code: int GetEncoderClsid(const WCHAR* format, CLSID* pClsid) { using namespace Gdiplus; UINT num = 0; // number of image encoders UINT size = 0; // size of the image encoder array in bytes ImageCodecInfo* pImageCodecInfo = NULL; GetImageEncodersSize(&num, &size); if(size == 0) return -1; // Failure pImageCodecInfo = (ImageCodecInfo*)(GlobalAlloc(0,size)); if(pImageCodecInfo == NULL) return -1; // Failure GetImageEncoders(num, size, pImageCodecInfo); for(UINT j = 0; j < num; ++j) { if( wcscmp(pImageCodecInfo[j].MimeType, format) == 0 ) { *pClsid = pImageC…

I want to write an assembly language program for nasm assembler which will read an integer and print the same in linux. The program should keep reading integers until a particular integer say 50 occurs. When 50 occurs program should not print it and exit. But I don't know how to input integer. Can someone explain and give the complete asm program? Thanks

Hi, I'm working on a socket debugger, I know there are plenty of this around, but I want to learn how to make my own in MASM32. Initially I'm trying to hook the "send" function from wsock32.dll then open firefox. I would like to replace the information being sent by firefox with "Gotcha". I used jaghook for this. So far it's not working. Does anyone have a clue why? replace.asm .486 .model flat, stdcall option casemap: noneinclude \masm32\include\windows.inc include \masm32\include\kernel32.inc include \masm32\include\user32.inc include \masm32\include\wsock32.incincludelib \masm32\lib\kernel32.lib includelib \masm32\lib\user32.lib includelib \masm32\lib\wsock32.libincl…

Hello, I search how i can get each commands of a debugged process in OllyDbg. I think i need to use this function : ulong Readcommand(ulong ip,char *cmd); My program entry point : 004C5C74 > $ 55 PUSH EBP var Commande : string;if Readcommand($004C5C74, PAnsiChar(Commande)) > 0 then // success else // error But when u try it, it's not working Readcommand return all time 0 ! I need to have : Commande := 'PUSH EBP' Can you help me ? Thanks, Mathieu

Hi Guys... Hope someone can help me out with a problem in delphi programming. First of all i'm coding in delphi since around 3 month. I want to describe my prob a little bit more... I'm using windows 7 x64. In win7 and also in win vista you can add program links to the task bar. But you can only do this when the string "IsShortcut" is written in the windows registry. When this string exists you have on your desktop some "freeky" arrows on your links. So i made a little app to write and delete this string to the registry. For now so good. But you only see the changes take effect when you log off and on again. Or you do a complete system restart. And theres my problem. I kn…

Hi, I need you help me. I want to use SetWindowsHookEx to hook a function exported from a dll to a run a process but it did not work. Detail: I'm have 3 files: Audition.exe, Hooker.exe & DllHook.dll, I'm using Hooker.exe to load that dll & execute function SetHook (exported in dll for Hooker.exe use it). SetHook function in dll will excute to use SetWindowsHookEx to hook a other function in dll into Audition.exe. If hook success it'll show a nag is the PID of Audition.exe process is running. But it's hook isn't success. I want to you help me. This is code in DllHook: Project: This is project of it, i uploaded in attachment file. I hope yous hlp me right now. Tkz…

Handy thing.

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…

Hello. I have no idea why this code won't compile. I get: error C2440: 'return' : cannot convert from 'char *' to 'const char' error. I compiled it before. Can anyone take a look at the solution and try to fix the problem? It is only few KB is size and project is already created. Thanks in advance! Project.rar

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

I have this problem need help, I created a button in VB.Net, then I make the following code VB.NET 2008: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click FileOpen(1, My.Application.Info.DirectoryPath & "\file.exe", OpenMode.Binary) FilePut(1, &H5003C0, &H7600) FileClose(1)This code will make the process as follows: First it will download a file (file.exe) to specify its path with the old file.exe will then open this file and overwrite. But here it just file.exe changed from old to new file.exe a new file, but does not override Please help me about this code in VB.NET 2008 Here's…

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…

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

Hi. I want to store floats in a tiny format. As small as possible eg to 8bit or 16bit. Anyone an idea how that could be done? I need to have a precicion of 3 digits behind the comma. Thanx in advance

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 …
