Resource 'hacking' is a different story. Windows has a defined interface (UpdateResource[^]) for modifying resources in executables.

For compiled C++ programs, this isn't generally possible. The compiler translates C++ source code into machine language. The resulting machine language does not contain sufficient information (at least in code compiled for release) to reconstruct the original source.

For .NET programs, compiled into IL, I believe it is possible to decompile those programs.

Hi guys,

I am developing a program that replaces executables icons with icons from other applications (executables) or from icon files. For now I am using this code in order to do it:

<br />
HMODULE hLibrary;<br />
	HRSRC hResource;<br />
	HGLOBAL hResourceLoaded;<br />
	LPBYTE lpBuffer;<br />
	HICON hIcon;<br />
	int skip=0;<br />
	<br />
	hLibrary = LoadLibrary(icon);<br />
	if((int) ExtractIcon(AfxGetInstanceHandle(), icon, (UINT) -1))<br />
		for(unsigned long n=0;n<=1000000;n++)<br />
		{<br />
			hResource = FindResource(hLibrary,MAKEINTRESOURCE(n), RT_ICON);<br />
			if(hResource)<br />
				if(skip==IconIndex)<br />
					n=1000001;<br />
				else<br />
					skip++;<br />
		}<br />
	else<br />
		MessageBox("The icon file or the first file contains no icon");<br />
	if(hResource)<br />
	{<br />
		hResourceLoaded = LoadResource(hLibrary,hResource);<br />
		lpBuffer = (LPBYTE) LockResource(hResourceLoaded);            <br />
		hIcon=CreateIconFromResource((PBYTE)lpBuffer,SizeofResource(hLibrary,hResource),1,0x00030000);<br />
<br />
		HANDLE hUpd=BeginUpdateResource(my_name,0);<br />
		UpdateResource((HMODULE)hUpd,RT_ICON,MAKEINTRESOURCE(1),MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),lpBuffer,SizeofResource(hLibrary,hResource));<br />
		EndUpdateResource(hUpd, FALSE);<br />
	}<br />
	FreeLibrary(hLibrary);<br />

So now I am using LoadLibrary, FindResource, LockResource to extract icon from executable or dll and then I use UpdateResource(...) to write icon to new exe. The problem is that this options does not suport icon files (.ico) and also it doesn't allow the user to extract the specified icon. I am using ExtractIcon() to get icon number.

Another way, more efficient and better would be to use ExtractIcon() to get icon form exe, dll or ico file. The problem of this mettod is that ExtractIcon() does not return a pointer to the data to be written by UpdateResource(...) instead it returns a HICON handle.
My question is how could I write this HICON handle to the new exe using UpdateResource(...). Itried several different methods but achieved one worked?

Please help anyone, this is very important to me.

Thanks.

Delete file at startup or shutdown

Hi,

What I need to do is schedule some files to be deleted either at shutdown or at startup. My application can't do this because it is closing after it creates them and they need to remain there until shutdown. My app is currentlly creatting bat files for each of them and adds them to Startup folder in Start Menu. This method is inneficient though. For example how do uninstallers delete their executable at shutdown (startup)???

Thanks,
Andrew

you can run an application as windows starts up

you make an entry in registry
HKEY_LOCAL_MACHINE\Software\Microsoft\windows\CurrentVersion\Run

in this key you make an entry and give your applications full path ,

this application now will run every time you start computer.

Have a good luck.

I can't use another app that deletes the files due to project specifications. I need somenthing more simple. I have been using bat files until now the console window showing at every startup was annoying. Is there a way to hide this window?? How do uninstallers delete their own bodies after uninstall??

Be carefull with the "MovefileEx" with the MOVEFILE_DELAY_UNTIL_REBOOT

From MSDN:
This value can be used only if the process is in the context of a user who belongs to the administrator group or the LocalSystem account.

Remeber One thing MoveFileEx only Work In Windows Multiuser Editions,if you are targeting your application to Win98 then for deleting file at Startup you have to write the entry in the WinInet.ini

It's an INI file, however for deleting it's harder because the format is:

[rename]
NUL=C:\\temp\\file1.exe
NUL=C:\\foo\\file2.exe

and so on. You can't use WritePrivateProfileString()because
the second NUL line would replace the first. You need to read
the whole file in,modify it, and write it back it again

Include statements

This seems to be something that's too simple to find an answer to, but it's starting to annoy me. All I know about C++ is what I've picked up myself, and I've never figure it out.

What's the difference between the types of include statements in C++? There's <thing>, <thing.h>, "thing.h", "c:\code\thing.h" etc. What's the difference? I know there's a difference, because changing the type has an effect on compiling.

Additionally, say I have a whole bunch of header files in a folder separate from where I'm working. Is there a way to set an environment variable or something so I don't have to type in the path to each one in its include statement?

Thanks for the help.

Re: Include statements

The only difference is where the file is included from.

#include "thing.h" - pick up thing.h from current directory
#include "c:\code\thing.h" - pick up thing.h from c:\code\ only (incidentally, this is really bad style - don't do this)

And the one you didn't specify:

#include <thing.h> - pick up thing.h from the include path

The include path is what you need to change to allow header files in a different directory to be found, without hardcoding the path (like the 'c:\code\thing.h' above).

How you change the include path depends on what compiler you are using, but if its VisualStudio then it should be pretty straightforward and you should look in the project settings.

You can have any number of include paths, and the compiler will look in each directory in turn. Make sure you don't have any duplicate headers otherwise you could confuse both yourself and the compiler!

I display a dialog box when double clicking in my ActiveX control.
It works fine. But When try to move the dialog box by pressing on the title bar it hangs. Why ? Anyone can help me?
this is the code
where setProperty just passes an object address. in the dialog box class i have a pointer to that. it just asign to that.

void CImgAnnCtrl::OnLButtonDblClk(UINT nFlags, CPoint point)
{
propertyBox box;
box.SetProperty(&m_TmpProperties);
if(box.DoModal()==IDOK)
{
/// just some calculations
}
}
