PE File Format differs by 16 Bytes in RVA of Import Directory Structure Section in Header...

Hello,

Am having a problem with PE file binary output.
We'd given our project to our client and the binary file generated by them is having a
[-> 3A48 [ 50] RVA [size] of Import Directory <-]

as offset address for import directory.

Where as the same project if we compile in our machine, it is
having a RVA a

[-> 3A58 [ 50] RVA [size] of Import Directory <-].

Both are differing by 16 bytes exactly.
Due to this the addresses referred are differing by 16 bytes in the file.

This is the only place where the address gets differred, due to this the

A sample dumbin out put of two files having only the headers alone are placed here.

Please help us in this regard to solve this problem.

I guess they've either got a dfferent minor compiler version or one or more Dlls on their system have more entry points than on yours. You need to compare the full verison numbers of all the statically linked Dlls, the Depends.exe MS tool is good for that also ensure that both compilers are identical.
You could try compiling without the /GS switch or its relatives so you get less compiler injected security stuff if you're not already doing this.
Make sure incremental linking is switch off and you're building everything from scratch.
I don't really see why it's a problem but I like a mystery as much as the next guy. Let me know if you get to the bottom of it.

Nothing is exactly what it seems but everything with seems can be unpicked.

Co-ordinates of buttons

Hi Forgive me for what is probably a very simple question!
I have 2 dialog applications that I am working on. In one I have laid out several button controls into various positions (dialog is maximized).

I wish to read these positions into another dialog app and display buttons in the same position. I have tried to get the co-ordinates from the '.rc' file, but when I use these in my 2nd dialog, they do not appear in the correct position or size.

Is the problem that I need to use ClientToScreen() or ScreenToClient() to convert the co-ords that I have?

I have looked, but have been unable to find a tutorial that will help me with this - anyone know of one?

Thanks for any help!

In the resource the controls are specified in client co-ordinates. And the controls are placed in the client co-ordinates. So it should be placed same as the first one.

Can you show me the relevent codes?

Hi - thanks for looking!

In the '.rc' file I have the following for each button control

CONTROL "",IDC_BTN_PA_001,"Button",BS_OWNERDRAW | NOT WS_VISIBLE,
12,305,40,18,WS_EX_RTLREADING

What I would like to do is use the '.rc' file from the 1st app to load up a 2nd app with the same resources, in the same locations. What I want to do is read in the co-ordinates and size (12,305,40,18 in the above example) into my 2nd app, and interpret the information to make the 2nd app display a button in the same location - either by SetWindowPos(), or MoveWindow(), or any other method that you may know of

I hope you can help!

Thanks

In the resource, the units are dialog units (DLUs).

From the docs:
"A DLU is based on the size of the dialog box font, normally 8-point MS Sans Serif.
A horizontal DLU is the average width of the dialog box font divided by four. A vertical
DLU is the average height of the font divided by eight."

For an example of how to convert DLUs to pixels, you may want to check out the
_AfxConvertDialogUnitsToPixels() function in the MFC source code or the
ConvertDialogUnitsToPixels() method in the ATL _DialogSizeHelper class.

fatal error C1853: in vc6

Hi,

I have to create a static library of a whole source code which contains ".c",
".cpp" files. I am using Microsoft Visual Studio 6.0, but i have the following error message which i am unable to solve.

The following is the problem,

fatal error C1853: 'Debug/<filename>.pch' is not a precompiled header file created with this compiler Error executing cl.exe.

I am inserting a ".c" file into my project which also needs to include "stdafx.h" but this header is not compatible with the C complier but this "stdafx" is an essential header for a VC++ project.

Please do help me on this issue of how to use the "stdafx.h" for a ".c" file.

Please note that I have also tried setting the "not using pre-complier header" Option in the Project->settings->C/C++ tab for every ".c" file I am using.

The following is the error i receive,

error C2146: syntax error : missing ';......
fatal error C1004: unexpected end of file found.

Advance thanks.

With regards,
Arul Prakash

.C and .CPP files are treated differently by the compiler. (Or so I think).

No! Dont do that!

Instead, switch your C-files individually to "Not using precompiled headers".

Thanks, It's working yar... I have created the standard library. Now i have to implement in the console application. I have import standard library in to console application. Finally i got two error. Can u please give me some solution's.

It seem as if the lib containing IperfMain::executeIperf does not get linked.
Check your linker settings.

Maybe you need to follow Karls advice and add "extern C" to the header/around the header inclusion.

When mixing C and C++, also don't forget to use the extern "C" directive for your C declarations so the linker will be able to do its job. More info there: http://www.parashift.com/c++-faq-lite/mixing-c-and-cpp.html[^]

IStream and XmlLite

* The xmlparser XmlLite from microsoft uses IStream to read and write xml.
It is described how to copy text into a stream, but not how to read the text back from the stream. Do you know how to do this?

Code to write text to IStream.
IStream * pStream = NULL;
HGLOBAL hXmlContent;
HRESULT hr;
int iResult = 0;

// allocate global memory to copy the HTML content to
hXmlContent = ::GlobalAlloc( GPTR, ( ::_tcslen( kpszXML_in ) + 1 ) * sizeof(TCHAR) );
if (!hXmlContent)
return false;

::_tcscpy( (TCHAR *) hXmlContent, kpszXML_in );

// create a stream object based on the HTML content
hr = ::CreateStreamOnHGlobal( hXmlContent, TRUE, &pStream );

Thank you for the link.

I also found another way to do this.

// Reset the seek pointer<br />
LARGE_INTEGER pos;<br />
pos.QuadPart = 0;<br />
pOutStream->Seek((LARGE_INTEGER)pos, STREAM_SEEK_SET, NULL);<br />
<br />
// Buffer to fill from IStream<br />
char pszXml[4095]; // char - Encoding dependent???<br />
ULONG cb=4095;<br />
ULONG cbRead=0;<br />
CString strXmlFromIStream;<br />
// Read the text from the stream on chunk at a time<br />
do <br />
{<br />
    memset(pszXml,0,4095);<br />
    hr = pOutStream->Read(pszXml, cb, &cbRead);<br />
    strXmlFromIStream += pszXml;<br />
} while(cbRead!=0);
