I've got an edit box created with the ES_PASSWORD style and I need to toggle that based on a checkbox (similar to what WinZip does if you set a password on a zip file).
On XP it's behaving weird. GetPasswordChar returns 0x25CF, which is the Unicode code point for the default black dot (this is an ANSI app BTW). I can turn the password style off fine with SetPasswordChar(0). But when I go to turn the style back on, I call SetPasswordChar(0x25CF) and it doesn't work, the edit box behaves as if I passed 0xCF instead, which gives Ï instead of the dot. Mad | :mad:

Any ideas how to get this to work in an ANSI app?

Pinky, are you pondering what I'm pondering?
I think so Brain, but if we shaved our heads, we'd look like weasels!

You might try using SendMessage(EM_SETPASSWORDCHAR,...) directly. It's possible the ANSI-ness of your application is confusing things in SetPasswordChar.

I've tried that too, no difference. Frown | :(

(I noticed that SetPasswordChar() takes a TCHAR and changed my code to use the raw messages.)

Maybe you can just create 2 password input boxes: one with ES_PASSWORD style, another regular EDIT. You will show just one at a time.

How to kill a process by its processID?

26-Oct-03 20:19

That's an interesting idea, I might try it Wink | ;)

There is a black dot character in Tahoma with value < 255 (I forget what the exact value is ATM) that looks almost, but not quite, like the default dot so I might just go with that.

Reuters eh? Sorry to hear that it's closing, but I had a miserable time there. Sigh | :sigh:

Hello, everyone!

Does anyone know how to kill a process by its process ID? Can anyone provide me some sample codes?

Thanks in advance,
Geo

HANDLE h = OpenProcess ( PROCESS_TERMINATE, FALSE, process_id );
TerminateProcess ( h, 0 );

Resources

If I add a text file as a resource, how can I write a new text file from that resource. Example... I have text files in my app, but I dont want to have to distribute the text files with it. I want to write temporary files and read from them, then delete them.

Thanks,
Daniel

I'm not sure I understand. You say that you do not want to distribute the text file.
Do you mean that you don't want to have separate files?

If so, then resources is the way to go!

How big are these text files?

Assuming that you have added the text files as resources to your app, you can simply call LoadResource() to get your text and from there create the temp files (if you actually need them).

Normally, there would be no reason to have a predetermined binary pattern (your text files) that would be written to disc and then read from. Why not just read the files' data directly from memory?

Have you answered an MTQ? Check out the stats!

Well... What I have is a listbox. Each line in the file is a line in the listbox.

For my purposes, this is what I'm doing...

CStdioFile MyFile;
CListBox MyListbox;
MyFile.ReadSrting(String);
MyListBox::AddString(String);

Thats in a loop until EOF is reached. If I could do this directly from the resource, that would be great.

Thanks for the reply.

Do you already know the value of the data? If not, resources probably aren't the answer.

I already know the valus... its all in a text file. Basically, what I want to do is read one line, and add that line to the listbox. Rightnow, i'm doing it by reading the text file. But, I want to add the text file into the resources so I wont have to distribute the text files with the app.

You can extract a resource to a file in this way:

bool ExtractResourceFile(const CString& resourceID, const CString& filename)
{
	// need to extract the resource out into the temporary filename supplied
	bool bOK = true;
	HANDLE hRes = ::LoadResource(AfxGetResourceHandle(), ::FindResource(AfxGetResourceHandle(), 
			resourceID, "YOUR_RESOURCE_TYPE"));
	if (hRes != INVALID_HANDLE_VALUE)
	{
		// we loaded it, now get the text from it
		DWORD sizeOfResource = ::SizeofResource(AfxGetResourceHandle(), 
			::FindResource(AfxGetResourceHandle(), resourceID, "YOUR_RESOURCE_TYPE"));
		char *lpRes = (char*)::LockResource(hRes);
		CFile file;

		if (file.Open(filename, CFile::modeCreate | CFile::modeWrite))
		{
			// write the resource out to the file
			file.WriteHuge(lpRes, sizeOfResource);
			file.Close();
		}
		else
		{
			bOK = false;
		}
		// release the resource
		::UnlockResource(hRes);
		::FreeResource(hRes);
	}
	return bOK;
}

Its up to you to delete the file once you have finished with it ::DeleteFile(filename)

To each a turn, to each a season.
A time to weep and a time to sigh,
A time to laugh and a time to cry,
A time to be born and a time to die.
Dust to dust and ashes to ashes,
And so I end my song.

how to add dynamically to Combo Box

27-Oct-03 7:31

Thanks Mr. Allen. Will this also work for binary files?

Edit...
Cant get it to work... always produces a zero byte file.

Hi,
I have MDI project. In one of the dialog boxes, I have a Combo Box,
and according to a file (this file is read before the dialog is opened),
I have to add items to the combo box, and the number of items is different according to the read file.

how can I add dynamically to the Combo Box?
