Retrieving PE file's import module names

Hi I am trying to get list of import module names from PE file. But i can not find the solution.
This is my code:

CString CPE::GetImportModuleNames(CString str_SectionHdrName)<br />
{<br />
	CString c;<br />
<br />
<br />
	IMAGE_DOS_HEADER * dosheader=(IMAGE_DOS_HEADER *)g_pMappedFileBase;<br />
    IMAGE_OPTIONAL_HEADER * opthdr =(IMAGE_OPTIONAL_HEADER *) <br />
                     ((BYTE*)dosheader+dosheader->e_lfanew+24);<br />
<br />
    IMAGE_IMPORT_DESCRIPTOR * descriptor=(IMAGE_IMPORT_DESCRIPTOR *)<br />
     ((BYTE*)dosheader+ <br />
     opthdr->DataDirectory[IMAGE_DIRECTORY_ENTRY_IMPORT].VirtualAddress);<br />
<br />
	// (?)<br />
<br />
	return c;<br />
}

In Documentation, it says:

" The IMAGE_IMPORT_DESCRIPTOR struct consists of five fields :

Union {
DWORD Characteristics;
PIMAGE_THUNK_DATA OriginalFirstThunk;
};
DWORD TimeDateStamp;
DWORD ForwarderChain;
DWORD Name;
PIMAGE_THUNK_DATA FirstThunk;"
...
"Name contains the a pointer (RVA) to the ASCII name of the DLL."
How can i retrieve the name of modules from that pointer(RVA).
Now i think i must write a loop and get the names but i couldn't do the the last step.

while(?)
{
descriptor->Name (?)
}

Could you please help me.
Thank you.

Pietrek has placed his code for examining PE files on the web. The articles of interest are:

* An In-Depth Look into the Win32 Portable Executable File Format, Part 1
* An In-Depth Look into the Win32 Portable Executable File Format, Part 2
* What Goes On Inside Windows 2000: Solving the Mysteries of the Loader

I used them as a basis for a couple of article I wrote a while back...

I knew these articles. But i couldn't find the solution from Pietrek's articles.
I need only last step.

Getting the length of a string of a buffer

Hello,

I have a buffer that contains words. However, the words comes from a client. I just want to get the words out. However, the buffer is being filled with rubbish after the words. Example "Manchester United&^&*#&#&##^&#@*&^^ etc.

How can I just get "Manchester United" out?

I have used the following using length and substring, but it displays everything

<br />
char buffer[256];		<br />
		sock.receiveFrom(buffer,sizeof(buffer), addr);<br />
		std::string message = buffer;<br />
		int strLength = 0;<br />
		strLength = message.size();<br />
		std::cout << "The length of the string is: " << strLength << std::endl;<br />
		message = message.substr(0,strLength);<br />
		std::cout << message;<br />

Many thanks,

Steve

Hi Steve,

Perhaps Socket.Available Property[^] will be useful to you.

ensure the buffer is properly initialized to all zeros and make sure to tell the sock.receiveFrom to not overwrite what could be the last null terminator

char buffer[256] = { 0 }; <br />
sock.receiveFrom(buffer,sizeof(buffer)-1, addr);<br />

char buffer[256]; <br />
ZeroMemory(buffer,sizeof(buffer));<br />
sock.receiveFrom(buffer,sizeof(buffer)-1, addr);<br />

But what happens if you then receive a shorter string of characters from the socket? Parts of "Manchester United" will still be intact. While calling ZeroMemory() may to work, a better solution was suggested by chandu004.

what roger has suggested is good.
but i think, your receive function should return, the number of bytes actually read.
so based on that number, you can cut your string to that many number of bytes.
im not sure but just try it out.

And then NULL terminate...

Here is a hint -> http://nibuthomas.wordpress.com/2007/09/24/moving-child-windows-of-a-window-at-one-go/[^]. The demo shows how to move all windows but you can customize it to do resizing of child windows.
