there no way AFAIK... but maybe he can write a temporary exe on the disk, ShellExecute() it, and when it exits, delete the file...?!

I want to execute exe directly from memory. I am writing a binder that will bind my project files and execute them to the memoty.I am doing this to make single exe out of several. Any idea or ref.

is it ok for you, instead of creating an exe "in memory" an launch it as is, to create threads and processes instead ?
as i am understanding your last comment, you're trying to make several independant units that are running separatedly (but maybe synchronized). this way, threads may be what you're looking for...

Well that sounds great.
should i load exe that is at the end of main exe file and create a process with the address of second exe.
well i have joined (appended) 2 exe files. now i want to load 2nd exe (which is at end of 1st exe) to the memory.

You can embed binary files as "binary" resources inside your exe, easy as embeding an icon.
Then you can save the binary contents as a "temporary" .exe, and execute it.
I hope it helps

I've a Project with many sub-projects attached to it, in that there are many MDI classes with several Dialogs. I need to change the property(appearance,font,color) of text in those dialogs, making it look equally applied throughout.
I dont think so, i can manually code every dialog to appear same, so i'm looking to write a class that would change the appearance of the text throughout the projects(all dialogs). I'm wondering how to go about this, any one could give me an idea in detail plssss.

I'm using ini file for translation purpose, and to translate dialog I have a call DlgTranslate(this) from OnInitDialog in every dialog. This function traverses all dialog controls, changing text accordingly.
This was long preface The key is that recently I need to adjust font of static controls, and doing this in DlgTranslate was a good choice (while not very structured). You can do similar thing in your case too.

Spirit[^] is an object oriented recursive descent parser framework implemented using template meta-programming techniques. Expression templates allow us to approximate the syntax of Extended Backus Normal Form (EBNF) completely in C++. Parser objects are composed through operator overloading and the result is a backtracking, top down parser that is capable of parsing rather ambiguous grammars.
The Spirit framework enables a target grammar to be written exclusively in C++. Inline EBNF grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable.
Spirit is part of Boost[^] Libraries, a peer-reviewed, open collaborative development effort.

Handle the WM_ERASEBKGND message for the dialog.
OnEraseBkgnd(CDC* pDC)<br />
{<br />
CRect rect;<br />
GetClientRect(&rect);<br />
pDC->FillSolidRect(&rect,RGB(255,0,0));<br />
return TRUE;<br />
}
this is this.

in the message map, is it ON_WM_ERASEBKGND() ??

Exactly.
In the message-map:
ON_WM_ERASEBKGND()
In the header:
afx_msg BOOL OnEraseBkgnd(CDC* pDC);
In the implementation:
BOOL CWhateverDialog::OnEraseBkgnd(CDC* pDC)
I am about to go eat some cake. Happy birthday to this!
this is this.

try this also , see what you get:
CYourDialog::OnEraseBkgnd(CDC* pDC)
{
return TRUE;
}
I've used this for writing joke programs for my friends sometimes

I have a function inside a DLL that acts as a hook procedure. it has an __stdcall attribute. When i tried to retrieve the function pointer via another exe with GetProcAddress it always fails, and it only works after i remove the __stdcall attribute. How can i retrieve the function pointer of this callback function properly?
Is there any difference in the way of retriving function pointer of regular function and callback function?
*** code ***
this is the hookproc function:
LRESULT CALLBACK HookProc(int nCode, WPARAM w, LPARAM l)
{
return CallNextHookEx(NULL, nCode, w, l);
}
and this is how i call it in another exe:
FARPROC HookProc = NULL;
HookProc = GetProcAddress(HookDLL, "HookProc");
*** end of code ***
thank you very much.

goto www.dependencywalker.com [^]and download the tool - use it to see how your function is being exported.
You can use a .DEF file to control how your function is being exported (see MSDN for details). You can also use the /EXPORT linker switch if you are using visual-c
