Pardon?
You have created a program, and want it to only be run once at a time?
This is a little bit hard, but there are plenty of examples on codeproject. Just search for "singleton", or "run once"...
You have created a program, and it opens a file, and that file should not be openable by anybody else?
That;s the default - but don't take my word for it: look at the documentation for CreateFile, and the sharing flags like (eg) SHARE_DENY_WRITE etc.

It all depends on how you are opening the file. In general, you want to open the file exclusively, or deny others read|write access.

http://dictionary.reference.com/browse/destroy[^]
Destroy:
1. to reduce (an object) to useless fragments, a useless form, or remains, as by rending, burning, or dissolving; injure beyond repair or renewal; demolish; ruin; annihilate.
You're getting the main window for notepad.exe - so it shouldn't come as a great shock that if you send a DESTROY! message, it closes. What did you expect?
Even if you actually had the text area for notepad, why on earth would you think WM_DESTROY would help you put a character there? I hope I'm missing out on something in your question that you didn't write down.
Your idea of sending a WM_CHAR isn't bad - but you're sending it to the main window for the application. If I use Spy++ on notepad, there are two child windows - a big edit one, and a status bar window. You could get the child window, and try sending the WM_CHAR to that. But that is implementation dependent. For all I know, notepad.exe under Vista is built completely differently. Maybe it uses a richedit window, rather than an edit one? Or Notepad under windows 2000 didn't have subwindows, it just worked as you expected.
I would have a look at WM_PASTE message. It's likely the notepad's parent window would pass it on to the child edit window to handle, and that would paste the contents of the clipboard into notepad. It is harder to set up some text on the clipboard - but there are samples on codeproject - and it would allow you to do more than one letter at a time.
I hope that helps,
Iain.

WM_DESTROY is a notification message from the system.
Sending it to a window that actually isn't being destroyed
isn't going to do anything except possibly leave the target
application in an unstable state.
What are you expecting sending that message to do?

I'm not an expert on such operations but
do you have tried it already with a WM_KEY_DOWN?

Uhmmm, are you sure the notepad is aware of such a message?

Hi to all.
I imported some files to resource (under ResourceView tab VC6). Main reason for this is so I don't need to distribute those files with application. In some time I need to load this files from resources and FTP transfer them away... How can I load them to say temp file?
Thanks in advance to all!

You can use FindResource to get an HRSRC handle to your resource.
Then SizeofResource to get it's size, and LoadResource / LockResource to get a handle on it.
Using that information, you can save the binary data to a temp file, then do whatever you like with it - including using APIs to FTP it somewhere.
Searching for those functions will give you their parameters.
Lastly, if you're using MFC, you may need AfxFindResourceHandle(?) to get the HINSTANCE the resource lives in in your app / dlls.
Good luck,
Iain.

Thanks you very much. I'll try to do so now!

Now when I loaded resource how I can save it to a file?
I created temp file but what api saves my loaded resource to a file?
THX

Using LockResource (as I said in my previous post), you can get a void pointer to the data (read only!), and using SizeofResource you get the amount of data.
So, you just need to save this lump of data to a file using WriteFile... Just as you would save any other lumps of data.
Have a look at GetTempFileName to get the filename for a throwaway file,
CreateFile to create it (oddly enough)
and WriteFile to save data into it.
If you look at the documentation for those, you should be good to go.
Iain.

There is an SQL forum. Maybe the people there can help you? This sounds more like a database question than a C++ one.
I'd help you if I could, but I have no idea about ODBC etc.

As a BLOB.

It's been many years since I've used SQL, but surely the concept is still the same. See here.
