Of course it will. That's because the edit control has lost focus. The code is doing exactly what it is suppose to.
A better solution is to handle the EN_CHANGE notification, and if the value in the edit control is ever greater than 3, disable the OK button. Doing validation is response to EN_KILLFOCUS is just the wrong approach.

You need to find the header in which this is defined, and then include it in your c file.

I know, but the header file must be if_ether.h or ether.h or if.h and the ETHER_TYPE_NULL don't existe in all of this files. What is the value for this constant??
thanks

I've spent a few minutes looking for it, and did not find. What kind of file uses this ?

Hi Everybody.
Please, I want to know I can draw a line on my dialog.
I really want to draw a chart on my dialog. The chart will have 2 axes (x, y).
Thanks.

Maybe you can take a look at the article I wrote (link in my sig). This is a chart control and maybe it can do what you are looking for.

probably custom control is the way to go, if you search here in cp you will find many good tutorial on how to dothat.

Do you know how to work with DC's
Get the dc of the dialog as
HDC hdc=::GetDC(m_hWnd);
and then use the line drawing functions to draw on the dialog through the DC
Once you are done with the dc release it.
Here's a sample code
HDC hdc=::GetDC(m_hWnd);
MoveToEx (hdc,0,0,NULL);
LineTo (hdc,100,100);
::ReleaseDC (m_hWnd,hdc);

Somethings seem HARD to do, until we know how to do them.

In WM_PAINT you can use from dc for draw line
CPaintDC dc(this); dc.MoveTo dc.LineTo(...) Is your purpose?

Show the code of the function (declaration and definition) and the way you declare it in VB.

On XP this can be done by simply holding down the Shift key when opening a folder whose view is already set to thumbnails.
Is this possible in win2000 by using MFC?
Thanks in Advance.

Hi all,

If you want to highlight a particular row, try this in your OnCustomdrawList function:
COLORREF crText, crBkgnd;
if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
if ( (pLVCD->nmcd.dwItemSpec % 3) == 2 )
{
LOGFONT lfFont;
CFont *pFont = GetFont();
_ASSERTE( pFont );
pFont -> GetLogFont( &lfFont );
CFont m_fBFont;
m_fBFont.CreateFontIndirect( &lfFont );
SelectObject(pLVCD->nmcd.hdc,m_fBFont);
crText = RGB(255,0,0);
crBkgnd = RGB(255,255,0);
pLVCD->clrText = crText;
pLVCD->clrTextBk = crBkgnd;
}
*pResult = CDRF_NEWFONT;
}
}
To color the background of a particular column, try this:
if ( (CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage )
{
COLORREF crText,crBkgnd;
if (0 == pLVCD->iSubItem)
{
crText = RGB(128,0,225);
crBkgnd = RGB(247,241,202);
}
else
if (1 == pLVCD->iSubItem)
{
crText = RGB(0,128,0);
crBkgnd = RGB(247,241,202);
}
pLVCD->clrText = crText;
pLVCD->clrTextBk = crBkgnd;
*pResult = CDRF_DODEFAULT;
}

A list has many parts - headers, rows or items, columns or subitems.... The text color of each can be changed; the background color (or what you call "highlight" color of each individual part can be changed.
When you say, "Change the highlight colour of listctrl please specify which part of the listctrl you mean.

Hi Everyone,
Visual Studio .Net 2002 with Service Pack 1
Windows XP Pro/Home with Service Pack 2
I have a multi threaded application (sometimes even up to 30 threads) and though that enabling Hyper Threading on my pc would obviously give an performance improvement, which is the case.
However, now (with HT enabled) I can still compile and program as normal, but I am experiencing severe instability problems. When the compiled application runs on another PC with HT enabled all seems fine, but when I run the application on a PC withouth HT, it crashes very frequently (usually withing 30 seconds) and very randomly.
If I disable HT on my development PC and recompile the application, it works fine on both HT enabled pc's and on pc's without HT. So the problem definately seems related to HT.
Are there compilation switches that I should enable/disable to fully support HT or multiple processors platforms ? Why does the HT compiled application crash on non-HT pc's ?
Thank you
Oliver
