Hey, thanks!

I'll try that, I think it would help.
I have three more questions though.

I guess I would have to change the font before writing the string. My application doesn't know in advance what language will be displayed. How do I dynamically find out which font to load? Isn't there some font that encodes ALL languages?

Secondly, suppose I have a Unicode string that is encoded in a single language. How do I find out which language it is encoded with? (Do I have to compare the characters to the Unicode table of languages, or is there a simpler way to do that?)

Last question - do I also have to take care of font selection when I work with the Rich Edit control, or can it select the proper font automatically?

Thank you very much!!
Oz

Hi Oz,

1) you should select the appropriate font for the respective language. "Arial" covers the most eastern and western languages including cyrillic, greek, and turkish. For asian languages you have to use different fonts: japanese - "MS Gothic", chinese - "MS Hei", korean - "GulimChe"...

As far as I know, there's no font that covers all unicode languages at once.

2) I guess you have no chance to retrieve a specific language from a unicode string by comparing the character values. There are too many characters which are used in more than one language. Just think about an 'e' ...

3) I haven't much experience with the rich edit control, sorry. But I remember that one must at least set the right font codepage for a proper display...

have fun...

ok, i'm posting this because i've been looking for this for so long...
Could someone please post an article explaining how to transfer files over a tcp winsock connection???? isn't this a very commonly used winsock-thing??? i went to codeguru and there was this short article but it didn't compile right and it was console based. I'd really like to know how to transfer a file, also larger files. I just dont understand blocking sockets very well.

Oh and also, what in heaven is Visual Studio .NET ??? is it just another IDE like visual studio C++ ?? or what?

THANKS
(please explain about the file transfer as i've been at this for way too long already.)

Look up CFtpConnection, CHttpConnection and CSocket in the MSDN library. Depending on the type of file transfer you need to do, at least one of these will be helpful. And follow some of the "How to" and "Example" links too.

rotating objects in OpenGL

How do I rotate a shape so that I can watch it actually rotate from its original position up to the angle of rotation I have specified. I always see the shape already in its final position when I run (not what I want).

ummm forgive me if i'm being too simplistic but...

your document holds the shape data ... your view shows it when an OnDraw() is handled

after initializing your shape co-ords do the Invalidate() thing on the view
do one stage of the transform
do the Invalidate thing()
do another stage of the transform
do the Invalidate() thing
etc
etc

like i said if i got the level of answer wrong forgive me

You can open the file with
fopen, and then use fread
Also you can use OpenFile and ReadFile

You can also use C++'s ifstream to read files. For more help see MSDN.

When my app runs, it gets an assertion error from strcore. I can enter the debugger with Retry and cancel, no problem. I even see what string is causing the problem. What I can't see is which of the many threads running am I looking at in the debugger.

Is there a way to tell?

Thanks for the help,

Question on CButton::Setmap

17-Jan-02 8:22

Hello,

I'm having some problems getting a bitmap to show up on a CButton. I followed what the MSDN documentation says, which is below:

******
CButton myButton;
// Create a bitmap button.
myButton.Create(_T("My button"), WS_CHILD|WS_VISIBLE|BS_BITMAP,
CRect(10,10,60,50), this, 1);

// Set the bitmap of the button to be the system check mark bitmap.
myButton.SetBitmap( ::LoadBitmap(NULL, MAKEINTRESOURCE(ADUSTBUTTON)) );
******

The bitmap is not loaded using this. It's just an empty button with no text. If anyone knows what I'm missing to Set a Bitmap and make it appear please let me know. I have no problems with CBitmapButton, I just don't need something so advanced. I appreciate your help.

Thanks in advance,
Greg

I need help with ShowWindow

17-Jan-02 8:10

have a dialog with several CWebBrowser controls and i want to show only one at a time, the rest must be hidden. The user must be able to select the browser to be shown.

I tried using a pointer in the dialog box that points to the currently selected CWebBrowser but when i used ShowWindow to hide the last selected CWebBrowser, i can't use the pointer anymore because it always sends an unhandled exception error when i try to call a function.

What i'm i doing wrong ?. Is there anotehr way to do it ?

Here is the source code:

void CClickMgr1View::SetBrowserCtrl(CWebBrowser* aCtrl)
{

m_browser->ShowWindow(SW_HIDE);

m_browser = aCtrl; // Here is where i get the error

m_browser->ShowWindow(SW_SHOW);
ResizeBrowser();

}

void CClickMgr1View::ResizeBrowser()
{
RECT rect;

if (m_init)
{
this->GetClientRect(&rect);
m_browser->SetWidth(rect.right-15);
m_browser->SetHeight(rect.bottom-15);
}

}

I think that aCtrl is a bad pointer....
Check the value of aCtrl.m_hWnd in the Function before to assign the variable to m_browser....

p2.x = 0.0f + (float)xspan/2.0f;
p2.y = (float)((0.0 - m_y1)/yw-yspan/2);
p2.z = 0.0f + (float)zspan/2.0f;

glVertex3f(p2.x, p1.y, p1.z) ;
glVertex3f(p2.x, p1.y, p2.z) ;
glEnd() ;

Anybody got any good tutorials for Exchange programming? I am not too familiar with it myself. I need to be able to iterate over all of the users on an exchange server and find out how much they've stuff they've got in their mailbox.

Any ideas, hints?

Thanks,

Go to the graphics book section, and look at the top sellers. Under Principles & PRactice you'll find the Red and BLue books, THE OpenGL books to own. The Red book is a tutorial, the Blue book is a reference. ISBN on the red book is 0201604582

Anyone know of a way to force an application to exit and then restart? The exit part is easy - it's the restart part that i can't figure out.
