Converting A File Into Bytes And Re Creating It

[BobTheBuildingBuilder]

Hi there, I would like to take some files I have, a dll and a inf file, and convert them into a char array, binary. After I have done that I would like to put them in my header file for example and than create file and write file the bytes into a dll or inf file that I had before. If there is an easier way through resources, I would be glad if someone could point me in the right direction to achieve my goal, that would be good as well.

everything is byte array already, so just open any file you want, modify and store like you would normally do.

I would like to put them in my header file for example ...

I followed what andywestken recommended and was able to create the files from bytes, but when I tried to do create file and writefile my dll, it had a md5 signature and the signature is gone. How do I create it from bytes yet keep the signature. Or do I have to extract it?

You can add any file as a resource. If you use VS, select "Import" in the Add Resource dialog.

To load the resource, call FindResource() and then LoadResource().

To get the size of the resource, in bytes, call SizeOfResource().
https://msdn.microsoft.com/en-us/library/windows/desktop/ms648048%28v=vs.85%29.aspx

To read the resource/binary data, call LockResource().

So basically what your recommending ahcfan, is what andy recommended. Taking bytes and writing to a create-file. I can do all this but I want to keep my signature of my dll, how would I be able to do this?

[ahcfan]

You asked in your post if there was an easier way using resources and I just posted the one way I know of. If you make a byte-by-byte copy of the original file then I figure the MD5 hash should be identical.

So the code

HRSRC hRes = ::FindResource(hInstance, MAKEINTRESOURCE(IDR_DRIVERRRRRR1), RT_RCDATA);
if (hRes == 0) {cout << "failed" << endl;}

fails with 0, and I managed to get my dll into a resource like this

Try calling GetLastError() to see why it fails.

The specified resource type cannot be found in the image file.

o-o How am I supposed to add the dll resource to look as if it were just another file.
