replace all of MessageBox's with
CString str;
str.Format("CreateFile failed with error %d.\n", GetLastError());
AfxMessageBox(str);

Then repeat your problem in board message.
If u wanna give a fast conclusion your message should be in first page of the forum.

Hi,

I have scanned in graphs which are now available in bitmap format and I wanna programmatically convert its curves (i.e. significant points) to coordinates expressed in numbers.

Please give me advice.

Hello,

I want to change FONT from one type to another type. Courier to Arial for example. Which function can help me to do that?

Thanks a lot.

Actually, your question is quite ambiguous but with my sixth sense around I try to answer your question. Smile | :)

I assumed you are talking about DC painting or drawing in a formview or dialog. To change a font type, codes are as below and comments do the explanation.

<br />
CFont      oFont;<br />
		oFont.CreateFont(11, 6, 0, 0, FW_THIN, FALSE, FALSE, FALSE,DEFAULT_CHARSET, OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS, PROOF_QUALITY, DEFAULT_PITCH | FF_MODERN, "Arial"); //Create Arial font type with certain behaviour. check out MSDN<br />
<br />
CFont* oPreviousFont = (CFont*) pDC->SelectObject(&oFont);<br />
<br />
		COLORREF colPreviousTextColor = pDC->GetTextColor();//pDC is your pointer to your device context. <br />
		pDC->SetTextColor(RGB(255,0,0)); //set to red color<br />
		<br />
                RECT _rect;<br />
                GetClientRect(&_rect);<br />
                CRect oRect(_rect);<br />
		pDC->DrawText("Hi, I am in Arial ",oRect,DT_RIGHT); //Aligns text flush right<br />
		pDC->SetTextColor(colPreviousTextColor); //change back to original text color<br />
	    pDC->SelectObject(oPreviousFont);	//set back to previous font type

Hope this helps.

Help with timer 8-J

I am making a timer program but I want it to stop at a certain number like 300. I made it so it counted but the timer wouldn't stop at a certain number i.e. 300.

if(m_iCount == '300')<br />

    KillTimer(ID_TIMER);<br />
    m_cStart.EnableWindow(TRUE);<br />
}

I have this in my Start button but I just realized that, that place is not a
very good choice (YAY). But I still don't know were to put it.....

I figured this out Laugh | :laugh:

see I had to include this in the wm_timer function or the OnTimer function, and had to change the statement to:

if(m_iCount == 300)<br />
{<br />
    KillTimer(ID_TIMER);<br />
    m_cStart.EnableWindow(TRUE);<br />
}

Hello,

do you know how to install the TCP/IP protocol programmatically? Normally you do this using the control panel but how to do it in a program?

-Dominik

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

You can not communicate with ports in NT (4.0,2k,XP,2003,++). That is only done with a device driver..

But direct access to I/O ports is restricted to drivers on modern OSes.

Visual C++ 6.0 SP5 - Debugger does not respond

zindines25-Jul-03 3:42

25-Jul-03 3:42

Hi all,

I am trying to debug an MFC application. Dialog Based.

As soon as I reach a breakpoint, neither of my application or MSVC does respond anymore.

The funny thing is if I start my application outside of the IDE, and if an exception is raised then I can enter the debugger without any problem.

Is there anything I can check so that I can understand/fix what is going on ?

Thanks for any help.

What OS are you using? I had that all the time on Win98 and ME. It was fine on Win95, and has been fine on XP. Any NT based OS should be fine. Make sure that you're using the latest service pack (at least SP5).

Hope this helps,

Ryan

Hy Ryan,

My OS is Windows 2000 SP3.

How do I know for sure that MSVC 6.0 is updated with SP5 ?
I did apply it but my experience tells me that sometimes some of the files in system32 are overridden by applications.

Added to that, it does it only with that particular application. I did reset all the settings of my project.

I am a bit lost. Never seen that before in 5 years that I am using MSVC 6.0

Thanks for answering anyway.

Yeah, sorry I can't help more. I don't have the problem on WinXP, that I use now, and I've never had 2k. It seems to be OS related though (in my experience), so you might want to check if there are any more SPs available for 2k. I'm not sure what the latest it.

Although, If it only does it for one application, it's wierd. Have you done a rebuild-all? Have you tried restarting the computer? Probably, but just thought I'd check Smile | :)

Others may have more they can say on this Smile | :)

it could be the application itself. Here is the obvious stupid questions in case you forgot to check something:

Do you use any unconventional libraries?
Did you try to break the execution by "break all"?
Do you use mix of MT(d), MD(d) libraries?
Do you have custom version of stl libraries?
Could your *.pdb files be out of sink?
Is it possible you have several versions of shared DLL's on your computer?
Did you install Java from Sun on your computer recently? Smile | :)

(Rational Rose, Corba, RealTime player)
What is your app actually doing at the time of the problem?

If you have all of visual studio installed, VB loads with an 'SP5' on the splash screen.

If you can dream - and not make dreams your master;
If you can think - and not make thoughts you aim;
