The PEF specification is a large set of rules that must be obeyed. Obeying some of them is insufficient to be a valid EXE file. So you could check a few of those rules to rule out the obvious violators, you would have to check everything to be absolutely sure it is a real EXE though.
If all you want to do is discard some obvious non-EXE files, look at the first two bytes, and a couple of the header bytes such as the e_magic field.

You may use such global (there are better ways, I believe), however you have to properly initialize it at runtime.

Have you intitalised hwnd to the handle of the text box? Perhaps if you show some more of your code it will become clear.
It's time for a new signature.

This is what i am doing.
I have created one dialog based application(say Test)
In that dialog,i have added one static text box(IDC_MYSTATIC).
From that dialog i am invoking another dialog(say Test1).
In that dialog,i have added a button as(Display message).
My plan is when i click that button.I want to display some msg on
(Test) dialog.
So what i am doing is:
IN Test.h.
extern HANDLE hwnd;
Then in second dialog.
In Test.cpp
HANDLE hwnd
Then on
DisplayMesage()
{
SetDlgItemText(hwnd,IDC_MYSTATIC,"ds");
}
I dont know whethier i am passing handle correctly or not.
I am getting hwnd as NULL
Thanks
Raj

If your code shows the actual runtime flow then hwnd is not initialized when you call SetDlgItemText.

Well you have answered my question with "no", so it is no surprise that it does not work. The value of hwnd must be the handle to the window containing the item that you are trying to set the text of. Defining a variable in a header file has no effect on this, you need to get its value from within your Test1 dialog. I would guess (if you are using DoModal() to run Test1) that the correct value can be found from the GetParent()[^] function.
Perhaps a bit more time studying the basics of Windows Programming (Charles Petzold[^] has written some excellent guides) would be useful.

Hi All,
I have a form view. I want to display this SDI to Half (Left)of the screen.
Again I have another form view. I want to display this SDI to Half (Right)of the screen.
How to do?
I have changed the CREATESTRUCT structure.
but it is not working.
Any idea.

You can use SetWindowPos() on your AfxGetMainWnd() after it has been created in your CApp::InitInstance()
|
|
|
|
|
OK SetWindowPos is working thank you.
|
|
|
|
|
You should go for splitter window.
See this sample SDI with split window[^]
Added: Are you talking about two different applications?

Although Niklas post is correct I should recommend to consider a better design.
Unless you are developing something very specific (like a process plant control synoptic) you should not manage how your window(s) appear on the user screen. You are not the owner of the user environment and the user may also have other application running, may be even more important (or less, depends on the circumstances) than your, and will perceive your popping out at the placement you decide as a sort of ... invadence.
Consider, instead, a different design where a single frame window contains two children (your actual windows), may be either managed through a splitter or with fixed proportional positions.
You decide how the children fits the parent, but let the user free to place the parent in his own screen.

Hi All,
I am hooking the ExtTextOutW to capture data before it is displayed on the screen. I use Detours and created a dll and I inject it into an application before it starts.
The hooking works as expected, the problem I face is in the string parameter that is passed to the ExtTextOutW function.
When I log the value of this string to a file, it prints some garbled values. I have been trying to find out why this happens and I found out that it is due to glyphs, fonts and unicode.
The application I want to hook will use only English characters, so I want to convert the glyph values into regular characters so that I can log the English characters that is to be displayed on the screen and not some garbled values that come in the string parameter.
I searched on the internet and I came across a post on this forum
http://www.codeproject.com/Messages/446094/Re-Could-not-hook-proc-CreateWindowExA.aspx[^]
Right now I am unable to purchase the book, so can someone please tell me how I can accomplish converting glyph to a string as Ivo Ivanov as mentioned. Ivo Ivanov, if you are reading this can you please help me.
Thanks,
mich

You should really buy a book about VC++. It is nearly impossible to help someone who has almost no knowledge of VC++ or C++ through a forum. It will take ages to explain some basic concepts. You will be much more efficient by reading a book first.

i think that's the best thing to do for now?.. read a book and understand the concepts and terminology used in VC++. anyway, thanks for the advice.

How did you end up in this situation anyway? Did you spice up your CV?

by the way, here is the app. that i was trying create. you can download the project and check it, it's just a design and no codes yet, i just named the controls to their ID's..
what i am tring to do is move the three buttons until they are totally out the the app window..
thanks for the help guys, appreciate it.
