You have access to the command line arguments at startup.

If you determine you don't want a GUI window to show then you shouldn't
show the window.

Create your main window without the WS_VISIBLE style. If you want the main
window to show, use ShowWindow(SW_SHOW).

If your main window is a modal dialog, don't call DoModal().

Try ::mbtowcs
And be sure to read the texts about conversion linked in that MSDN-Article.

Have you considered the A2W() macro?

You can use GetVolumeInformation.

see if the following logic works.
say for exmple, your CD drive is "G"
_chdir("G:");
_findfirst();//not sure about the parameters. find them out. otherwise i have to refer my backups.
if find first detects something, then, cd is available.
otherwise not.
simple.

prefix your main thread subject with [SOLVED] if it is solved.

If you download and play with my article Detecting when Drives are added or removed[^], then you will have a handler for WM_DEVICECHANGE.

Putting a breakpoint in, I notice that WM_DEVICECHANGE gets called with a parameter of DBT_DEVICEARRIVAL when a CD is inserted, and the drive has spun up, and DBT_DEVICEREMOVECOMPLETE when the CD is ejected. Both of which I handle nicely!

Detecting if it's blank or not would be a different question, but my code will solve the problem you have.

Retrieving PE file's import module names

serimcc16-Oct-07 20:14

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.
