Hi all I'm trying to convert this small c snippet to delphi 7 code but without success for now. If any delphi coder could help I'll be gratefull. HANDLE hthread; hthread = CreateThread(0, 0, &animate, hWnd, 0, 0) DWORD WINAPI animate(HWND hWnd) { unsigned char wincaption[32]; unsigned int i; SendMessageA(hWnd, WM_GETTEXT, 32, (LPARAM)wincaption); do { for(i=0;i<20;i++) { if (((wincaption[i] >= 0x41) && (wincaption[i] <= 0x5A)) || ((wincaption[i] >= 0x61) && (wincaption[i] <= 0x7A))) wincaption[i] ^= 0x20; SendMessageA(hWnd, WM_SETTEXT, 0, (LPARAM)wincaption); Sleep(500); } } while (1); } And my delp…

Window hook using Python callback + DLL
by demberto- 2 followers
- 6 replies
- 4.5k views
I was wondering whether, I could do this: 1. Create a DLL with a method to register a callback function written in Python. 2. The DLL calls SetWindowsHookEx internally, registers a proxy function in the DLL itself which calls the Python callback function. 3. Load the DLL in Python with ctypes and call the callback registration method it exports. I briefly tried this but SetWindowsHookEx fails for global hooks. I see no reason for it to fail. Also according to the documentation I pass NULL for the hMod arg of it which is used when the hook procedure is inside the DLL itself. Maybe I think SetWindowsHookEx will need another injector process which is not …

Hi everyone. I'm looking for a tiny library in C/C++ (or binding) that able to: - Evaluate simple x86/x64 assembly codes (execute codes from a string to get output). - Each asm instruction has callback or hook (at least memory access instruction, for several special purposes, E.g. using ReadProcessMemory to read memory from other process, etc). Maybe a little bit like a VM. MOV RAX,$INPUT ADD RAX,8 MOV RAX,[RAX] # eg. memory access instruction MOV $OUTPUT,RAX Hint me. Thanks.

hi all, this is a recompilation of 2009 setup I made... whats new @ rebuilt on INNO6 removed FPWPP.DLL (basically the main reason of recompilation is this, the 2009 setup, stuck on win10x64 machines due Frontpage DLL registration!!) optimize Extra Components by14mb to 686kb dn 16.3mb @ mir.cr/S4SZWQK6 or upload.ee/files/14138148/Microsoft.Visual_Basic_v6.0sp6.upd2022-whoknows.rar.html

Hello guys. How is going ? Can anyone help me with this ? I'm searching for a reason for this to happen. My application uses DirectInput, it uses GUID_MouseSys. Sometimes when the app crashes it go back to visual studio but the cursor is VERY laggy as all action with keyboard too. Alt + TAB delays at least 2 to 3 seconds... Anyone knows why this happen ? Or at least can help to try to investigate the problem ? Thanks! ---- Edit Strangely if start debugging session and keeps maintaining focus on VStudio everything stays normal. I think it's related to windows focus. But I can't really say it.. Any tips ?

Hi guys, today I would like to ask how to implement a 100% working handler to log exception.So in the past I tried already to do this and its also working so far but I think its not working always so that the reason why I do ask to know how to do it correctly.So the main basic way I choosed is only using SetUnhandledExceptionFilter API with address to my Handler routine to read exception infos / log them / MessageBox them. invoke SetUnhandledExceptionFilter,offset HANDLER_SEH2 HANDLER_SEH2 proc log code etc invoke MessageBox,NULL, BUFFIS,chr$("Exception Info!"),MB_ICONINFORMATION mov eax, 1h ret As result I get this so far (mostly)... 30.08.2017 21:00…

Hi guys, I see some problem when using the normal GetPrivateProfileString & WritePrivateProfileString function to store lines into a file and read them.All works for normal lines without CRLF but the GetPrivateProfileString function dosen't read the stored multiline/s which was saved with WritePrivateProfileString function. Why do they differ?Write works & Read not?In this case I can not use GetPrivateProfileString function to read some entry from file. I'am using a edit control with multilines & wantreturn style and wanna save / read whole text parts to file.How could I do that in best case?Just asking before whether they are any functions I could …

Hello. During coding a keygen i have this issue. The keygenme calculates a SHA-256 which is stored in a string. After that it adds DWORD values of the SHA. Because my english is not so good to explain i put a simpler (similar) example to see whats going on. I have make some progress but i have stuck one this: Why sscanf doesnt put in eax the correct value starting from sha_256[0]. (Eax should contain the value 0x64ec88ca) How i can fix this? -Thank you

capstone vcpkg package broken?
by deepzero- 1 follower

I am porting some tools over to vcpkg package manager. Maybe it's just too late, but it seems to me the capstone package on vcpkg is broken. Installed with vcpkg install capstone:x64_windows. The following: cs_open(CS_ARCH_X86, CS_MODE_64, &handle); returns CS_ERR_ARCH, because the x86-init function in static cs_err (*cs_arch_init[MAX_ARCH])(cs_struct *) = { in cs.c is Null. Which would suggest that CAPSTONE_HAS_X86 was not defined during compilation of the package. Can someone confirm this?

Hello, I'm working on a x64 Framework 4.7.2 application obfuscated with Crypto "x64 Crypto Obfuscator For .Net v7 (v2020)", I'm able to restore strings and mostly deobfuscate the app but I'm having difficulties with restore delegates. Here's an example public GForm4() { this.method_6(); Delegate108.smethod_0(Class0.smethod_0(6600) != 0); Delegate60.smethod_0(this, new EventHandler(this.method_0)); } Unfortunately most of @CodeExplorer / SnD's excellent tools give an "invalid assembly" error as it's x64? I'll be grateful for any tips or tools to restore delegates please. thanks in advance
