Why? What's the error message?

No. WindowProc() is never called directly. It is called by the framework.

CSliderCtrl - dotted focus rect

Hi
I have a CSliderCtrl which I have placed within a CDilaogBar. As soon as the control gets focus a dotted rectangle appear around it. How can I get rid of this? Is there some style which I can change? I don’t get the rectangle at all when its on a plain CDialog.

Cheers
Rich

Handle the reflected NM_CUSTOMDRAW and then clear the CDIS_FOCUS flag from theNMCUSTOMDRAW::uItemState during the CDDS_PREPAINT stage.

Home-grown tooltip window

I can't use the MFC-supplied tooltip handling (on a CFormView) because it doesn't return tooltips for a static control (with an ID) or for CDateTimeCtrl, so I've come up with my own code.

I've got my tooltips showing up, but they appear to not be "on top". By that, I mean the tool tip shows up, but it's partially hidden by any controls that might occupy the same part of the screen.

I've tried BringWindowToTop(), as well as SetWindowPos(&Cwnd::moveToTop, ...), and even SetWindowPos(Cwnd::FromHandle(HWND_TOP), ...).

Any help?

Are you using the WS_EX_TOOLWINDOW style as well as WS_EX_TOPMOST. Also try making it a child of the desktop so that it is not a sibling of the controls on your form.

I'm calling ::GetSysColor(COLOR_INFOBK), and it's returning white, despite the fact that my tooltip background color has been set to yellow. Does anyone have any ideas?

Does GetSysColorBrush(COLOR_INFOBK) work?

Bernie (Boom Boom) Geoffrion worked Atlanta Flames games in the 1970s with the splendid Jiggs McDonald. One night, Geoffrion said, "Jiggs, there are only three things to hockey: shooting and skating." McDonald said, "Right, Boomer. And what's the third?" The exasperated Geoffrion replied," Jiggs, that's the three. Shooting. And. Skating."

Well, since this particular color definition has been available since win95, i think i can be pretty sure that function will work. BTW, I'm getting the color for the text (COLOR_INFOTEXT).

One would think that GetSysColor would work too, but in your case it appears to not be. GetSysColorBrush will return NULL on error, where as GetSysColor does not have a reliable error check mechanism. Also if GetSysColorBrush(COLOR_INFOBK) also returns a white brush then your system settings may not be what you think they are.

The easiest option would be to handle custom drawing. The mechanism is pretty straight forward. Take a look at the NM_CUSTOMDRAW message in the MSDN. I couldn't see any articles for tree controls, but this[^] article for List Controls got me first started.

Is there an easy way to do the following:
1) find out how many files there are in a particular folder
2) find out the names of the files.

The simpler the solution the better.
thanks

Use the FindFirstFile()/FindNextFile() pair for both.

    char *szReceive;<br />
    int nr;<br />
    szReceive = new char [(nr=(pCom->SizeUsedInRXBuf()+1))];	<br />
    memset(szReceive,0,nr);	<br />
    pCom->ReadBuffer(szReceive,nr-1);<br />
    CString str,toto;<br />
    m_Edit.GetWindowText(str);<br />
    str+=szReceive;<br />

this is a function i use to convert BYTE arrays to hex strings. maybe it will help...

CString HexDump(BYTE *pData, DWORD dwSize, int imax)
{
	CString out;

	for (DWORD i=0; i < dwSize; i++)
	{
		CString f;

		if (pData[i]<16)
			f.Format("0%x", pData[i]);
		else
			f.Format("%x", pData[i]);
		
		out+=f;
	}

   if (imax > 0 && imax < out.GetLength())
   {
      out = out.Left(imax);
      out+="...";
   }

	return out;
}

Looking at the formatting of the code reinforces my belief that using tabs for indenting should be banned. Use spaces only. No matter how careful you are to try and use tabs, somewhere in the code you are going to press the space bar 4 times rather than the tab key once. Now when the code is viewed with a different tab spacing it looks all screwy.
