Cuda force use mad.lo.u32 for ROTATE_LEFT ??? Compute Capability 1.2 __global__ void fun(unsigned int * mem) { int a = 3; int b = 5; int c = 6; int d; asm("mad.lo.u32 %0, %1, %2, %3;": "=r"(d) : "r"(a), "r"(b), "r"(c) : ); // d = a*b+c *mem = d; } This produce good result, anyway when I define (try): #define ROTATE_LEFT2(x, n) (int)x*(1>>(32-n))+(x<<(int)n) there is no mad instruction.

I know I can do it with dnlib or one by one with DnSpy, but is there other app that ready to use for doing this? example, I want to replace ldc.i4 50 call int32 MyApp.MainForm::getInt(int32) with ldc.i4 5 nop

Hello, My question is simple. How we can detect the first window of a program which is created by CreateProcessA api? My objective is simple 1. create process with CreateProcessA api 2. Wait for first window to appear (same like advance loader generator) 3. Suspend thread and patch bytes. Can someone please help me to know how I can wait till the first window appear?

Hi guys, today I have some questions about a problem I have using WinSock APIs and maybe you could help to find & fix the problem reason. So before a while I coded a tool to check many diffrent internet links from same server only with sending a HEAD requests and checking the status value of response.All was working so far without problems.Now I changed my internet provider to get a better internet connection / speed etc and I also have a new device / router I do use for this and with that I get always this problem.On the first view all is working as before too but with the diffrent that after I did send some requests (30 - 50) it stops for some seconds and …

Hi guys, I am looking for any engine to build a browser in a app window for MASM.I found some example sources using some IWebBrowser2 (IWB2.inc) but it has no descriptions inside how to use it etc.Just would like to know if there are any hlp file to download to know how to work with it?Also wanna know how save it is using something like this.If I see it right then its using the IE stuff for browsing.In this case I also dont know whether its doable to create a own popupmenu sending data to my app itself you know.Not sure about that yet.Maybe anyone has some hints for me.Below I did attach a example source I found. 9957_Browsertest.zip greetz

Hi im trying to code anticheat in c# for unity games But i cant detcted dll injection actually i try loaded dll and moudel but itsnt work becuse its mono inejection Any buddy can help me?

I would like to know how most of the software developers create their own licensing key system. I would like to create my own one for my software application. I believe it is something related to cryptography. As I am already using Crypto++ library in my application for MD5 and SHA1 hashing, I would be happy and thankful if someone with expertise explain to me how to do it. NB: I mainly use C++ in my coding. Also, I need it to be related to a hardware number obtained from a USB connected SIM card in the format of 123456789, so the end-user will only send me that number and I will send him back the license key. TIA.

Hi guys, I have a small question and dont remember anymore the answer at the moment so maybe you could help quickly. How was it going to load a module / dll into own & other process without to execute the init / run of the dll?Normaly if I am using LoadLibrary / Ex function the dll was running the init = did run on time from EP etc.In my case I wanna load the dll then changing some code in the dll and then it should process the init / EP etc you know what I mean right? In OllyDBG its like if you would enable the option "Break on new module".If Olly stops then I can see whole dll code in memory map and can also set a BP at EP for example to stop there.…

hi anyone can help?

Having those different ways of doing leftrotate: versus: Which one would you choose? The second one without temporal variable? The speed difference seems to be small - can be a speed calculation bug.

I use Visual Studio 2010 Enterprise! In a Visual Studio project barswf_cpu.vcxproj I've saw this <ClCompile> <Optimization>MaxSpeedHighLevel</Optimization> Apparently this value is not valid, https://docs.microsoft.com/en-us/cpp/build/reference/o-options-optimize-code?view=vs-2019 I've replaced that (MaxSpeedHighLevel) with: <ClCompile> <Optimization>MaxSpeed</Optimization> Now compiles, the problem is that speed is of 45 MHashes/second instead of 60 MHashes/seconds (in already compiled exe by someone else) - so the speed is 25% slower. Anyone know what is with MaxSpeedHighLevel ??? And …

Detecting Advanced Vector Extensions (AVX) support in Visual Studio??? https://insufficientlycomplicated.wordpress.com/2011/11/07/detecting-intel-advanced-vector-extensions-avx-in-visual-studio/ The problem is that I have Visual Studio without Service Pack so _xgetbv method can't be used!

Hi again. BarsWF once again. So the CUDA project I got it working. The SSE2 project is still bogus.

Visual Studio 2010 include library: So I once again have a question: I need to include: https://github.com/jmendeth/ccv15/tree/master/libs/poco I found this info: https://docs.microsoft.com/en-us/cpp/build/walkthrough-creating-and-using-a-dynamic-link-library-cpp?view=vs-2019 So the first thing I do is copy "include folder" to D:\BarsWF-master\Poco and that thing seems to work just fine. Now the compiler complains: 1>LINK : fatal error LNK1104: cannot open file 'PocoFoundationmtd.lib' Already tried Project Properties -> Linker -> Additional Library Directories No good result!

How to get the RVA of a method from MethodBase/MethodInfo?

Hello guys, I'm trying to rebuild the PE sections because I want to reorder them. Has someone done this? What are the requirements for that? Some addresses are linked to certain directories and the padding between them? Any possible examples? I'm asking that because usually .reloc section is the last one and when I add a new section, it comes after it.

Hi guys, can anyone tell me how to handle a proxy using windows socket & OpenSSL functions?So I get all working on normal way to call any addresses and to get response but now I tried to do the same but with any proxy address but get some issues.So what is the correct way to handle the proxy address before handle the main request address / header?

I got (Failed to get Base of kernel32) What i did is just intercept the calculate function inside another form application. Is there any simple application for injecting dll ?
