Here's some documentation from microsoft: http://go.microsoft.com/fwlink/p/?linkid=84140
But it doesn't really go into the corner cases. It's more focused on documenting how they think the PE format should be used than on documenting just what sort of insanity is actually accepted by the loader (which of course varies per version of windows). As far as I know MS doesn't even document that, I've only seen it in places such as corkami's github and places that talk about analysis of malware. For example, sections can actually overlap each other in virtual space (wat), with sections that are later in the section table apparently just overwriting the mapping created for an earlier section that extends further than where the later section begins - MS does not even seem to acknowledge that such a thing is possible.
Here's an other description of the PE format by corkami, including a lot of useful practical notes (or gory details..) and references to the POCs in the list I linked before: docs/PE.md at master · corkami/docs · GitHub
Thanks for the links. However, it leads either to Old Documentation (1999), or CE formats.
I have the Old Formats already, via the books of Matt Pietrek. Other persons have also contributed, and I have now written a suite of functions that extract imports and exports. The next step is to extract and show resources. Matt Pietrek found that too trivial an issue to pass any remarks on. I suppose it wil take a bit more hard slogging.
I am avoiding LoadLibrary(..), EnumerateResources(..), LoadResource()and similar kernel functions, because I am trying to write a tool that can analyse what went wrong where any of these kernel functions fail. The Kernel functions on an end user computer do not allow for debugging there and then.
They are nothing to do with the kernel, but part of the Windows API.
If you click your mouse to the left of the document name on the picture page until a sort of square appears, you then get the Next button lighting up so the download works. Took me a couple of seconds to figure out.
I Agree that some of the mentioned functions are actually part of the Windows API. Nevertheless, I still want to load a PE File and analyse it on my own terms for my stated reasons. By the way, LoadLibrary() is definitely a Kernel function (in as my Program shows, Kernel32.dll).
When clicking the Download button on the MS Website, I get a screen which states that I have No File selected for downloading.

I have a List:
Maybe post the compilation errors that you are seeing along with the pertinent code.

I am working LDPC encoding and decoding for hardware implementation.Through Vivado HLS, I need to transform a parity-check matrix H (that only consists of ones and zeros) from a non-standard to a standard form through C/C++ programming language. Here below you may find samples of non-standard parity check matrices in which Gauss-Jordan elimination (over GF(2)) can be applied.
Initially, i am trying encoding part via C/C++ programming logic. please help me if you do have any idea about LDPC. I would need a method that works out with matrices of any dimension.
thisis, express it as
Hsys = [I| P]
This is my H matrix
H=[1 1001010010111100 1];
Expected Systematic H matrix
Hsys=[1 0010101011100101 1];
int main() //THIS CODE WORKS ONLY FOR THE GIVEN MATRIX BUT I NEED A METHOD THAT WORKS OUT WITH MATRICES OF ANY DIMENSION
// encodingint i,j;
H_Matrix[j] = temp[j];
H_Matrix[j] = temp[j];
H_Matrix[j] = temp[j];
We have a MFC application with a structure that constitutes int, float and char array members. We have declared a global pointer to this struture. This application creates a shared memory using createfilemapping function and assigns the shared memory to this global variable using mapviewfile function.
The same structure is used in a console application1 which is used for doing certain calculations. This console application shares the memory created by the MFC application using openfilemapping and mapviewfile functions.
I want to create another console application2 in which the dimension of the array members of the struture to be modified. If I run the MFC application based on the selection 1 dynamically, it should create the shared memory for console application1. Similarly for selection 2 dynamically, the MFC application has to create shared memory for console application2.
Please suggest me how to do it dynamically when I run the MFC application
Note: When the MFC application is run, it invokes the console application after creating the shared memory. It invokes one console application during its each run based on the user selection.
Yes it is possible but now you need another global variable to tell which structure it points to. Better to have some flag in the structure, preferably the first item, which tells the rest of the code which one it is. But really using global ob jects/pointers in this way is not good design.
If I am going to have a single pointer which will dynamically point to any of the 2 structures based on the user selection, then what should be pointer type defined...struct1 or struct2 or void
I have to define the pointer type while I code and point it to any of the strutures dynamically based on the user selection which is mostly one time. After the selection is done, the pointer will point to the selected structure throughout the application run.
