Hi guys, so I got following problem.So you know the VLC player which you can also use to enter direct URL addresses of video files to play them.If I use this function then all is working well and the video will played normaly and liquid as it should.Now I wrote a WinSock code to download the bytes and write them into a name pipe handle created for VLC process and started the player via ShellExecuteEx.The VLC player starts and does play the video reading the bytes from pipe.All is working fine so far but the video dosent play liquid and it lags / jerky etc so its not good and also not playing same if I enter the URL in VLC.So I dont find the problem reason in this cas…

Hi again, I made a listview with seven columns and used LVS_EX_GRIDLINES.I also did subclass the listview.If I now add much entrys then I get a VScrollbar to see which I can move.If I now press on the bar free parts (not slider itself) then the slider jumps up or down etc and the problem now I get is that the GRIDLINES are doube to see in each line = the entrys itself are crossed out and its looks very bad and in this case I have to do any refresh.In my subclass I added now WM_VSCROLL message and added.. .if uMsg == WM_VSCROLL invoke InvalidateRect,hWnd,NULL ,FALSE invoke UpdateWindow,hWnd ...and the listview gets updated and the representation looks good aga…

AssemblyNameIniter
by CodeExplorer- 0 replies

Will get AssemblyName from a file name or from a byte array withouth loading the assembly. In Program.cs you will find a short example, all you have to do is call AssemblyNameInit.GetAssemblyName methods, and it will return an assembly name; you can also use AssemblyNameInit.GetAsmRefsAssemblyName to get AssemblyName array of referenced assemblies.

PE structs question
by LCF-AT- 6 replies
- 5.3k views
Hi guys, I have a new problem and wanna find a solution.So at the moment I try to work with the PE structs and found something strange.My goal was it just to read some PE Header datas just to check whether the file is a NET target or not (optinal also to find the NET version the file needs to run if possible). So the IMAGE_NT_HEADERS structs points me to the OptionalHeader IMAGE_OPTIONAL_HEADER32 struct and this points me to DataDirectory IMAGE_DATA_DIRECTORY struct and there I have this... IMAGE_DATA_DIRECTORY STRUCT VirtualAddress DWORD ? isize DWORD ? IMAGE_DATA_DIRECTORY ENDS ....that all?Why this?If I follow the way in Ol…

Hi guys, so I have just a little question about static libs (dont find any older topics to post my question). So I wrote some dll code and created some export functions with MASM and now I have the normal buld lib of the dll like other libs like kernel32 etc (you need to have kernel dll).Now if I build a new project and use my lib with some functions then it will also need the dll where I used the lib from and this I dont wanna have and would like to build a static lib from my lib so that I dont need the dll itself later in my project.All clear so far right.Now I used a tool called dll to lib to build a lib from my dll (which is in MASM compiled dll) to get a st…

I'm trying to learn Reverse Engineering, at this time I compile C++ code without any optimization and see the correspond assembly in IDA's disassembler, but there are some parts of the code, where I can not guess what happens. I think many of you can help me to answer this questions C++ code: #include <stdio.h> #include <string> void fillarray(int is[11], int size) { for (int i = 0; i < size; ++i) { is[i] = i; } } int main() { char* chr = "First"; std::string m = "Secdond"; static int arr[11]; std::string m1 = "Third"; auto size = sizeof(arr) / sizeof(arr[0]); fillarray(arr, size); int num = 11; printf_s("%d", num); get…

Hi I'm looking for example on creatingprocess and then acquiring it's context via GetThreadContext without using DEBUG_PROCESS or DEBUG_ONLY_THIS_PROCESS. If I use CreateProcess with only CREATE_SUSPENDED flag I end up with ERROR_NOACCESS as my thread have no THREAD_GET_CONTEXT attribute. I've tried to use SetSecurityInfo but without luck. If someone have other ideas I'll be glad to test them.

Hi guys, so I just have a small question about the SYSTEM_INFO struct and checking the wProcessorArchitecture type to check whether the running OS is x86 or x64 version.So if I read it right then its enough to checking the wProcessorArchitecture type only to get the info about x86 / x64 any "no matter" if I call GetSystemInfo / GetNativeSystemInfo from a x86 or x64 application right?So in this case I dont need to check for IsWow64Process API. If so then I have a add on question.So I found a code about checking Win versions etc and at the end its also checking for wProcessorArchitecture to send output whether its 32 or 64 bit Win version (all clear so far).....BU…

Hi guys, short question.So is there any tool out there what can check other PE files and can give info about this PE file about whats the minimum required OS to run this PE file?

API NAME | Minimum supported client ------------------------------------------------------- GetModuleFileName | Windows XP GetVersionEx | Windows 2000 Professional VerifyVersionInfo | Windows 2000 Professional IsWow64Process | Windows Vista, Windows XP with SP2 ...... …
