Read dll from source instead of disk? #7

Closed Baseult closed 2 years ago

Baseult commented 2 years ago

Hey, I wonder if it would be possible using your project to manual map from source rather than "ifstreaming" the dll from disk.

I tried it the following way but had some issues:

  1. Imported the Dll into HxD and exported it as C.
  2. export looks like this: char rawData[2785280] = { 0x4D, 0x5A, 0x90, 0x00, 0x03, 0x00, 0x00, 0x00, ... };
  3. Added export as dlldata.h to the Project
  4. replaced the following code: std::ifstream File(dllPath, std::ios::binary | std::ios::ate); with std::ifstream File(rawData, std::ios::binary);

Result: got an error at if (File.fail()) "Opening the file failed:"

So I changed it from std::ifstream to std::istringstream, also had to change it to: auto FileSize = sizeof(rawData);.

This almost works but I get an error in Injector.cpp saying "Invalid platform" now.

So now I've reached a point where I don't know what to do next. Would be great if you could help me out as I'm almost finished but cant get it fully working.

Thank you very much.

Just remove File stuff and use directly your raw data, why you want to make it more complex:

BYTE pSrcData = (BYTE)rawData;

auto FileSize = sizeof(rawData);
