I decided that your method was SO much nicer that I would throw out what I did and use your method. Just for general education if you happen to know how I would capture the WM_PAINT for the static control, it would be nice to know. In any case, I will no longer pursue it so it is of minor importance.
I threw out the WM_PAINT message, threw out the invalidateRect and I just call it once. It turns out that I need an initialization routine for setting up the radio buttons depending upon the study type. It was most natural to just call my routine from there (like your WM_INITDIALOG suggestion).
My code is simpler now:
void CMyToolbar::SetPatInfo(void)
{
// font size can start at 16 if 3 lines are permitted.
// start with font size = 12 for 4 lines.
int fontSize = 120;
int i, j;
CFont hFont, *hOldFont;
CWnd *wnd1;
CSize sz1, sz2;
CRect rc1;
CString textOut[4];
CDC *pDC;
CCardiacDoc *pDoc;
CCardiacView *vw = CCardiacView::GetView();
pDoc = vw->GetDocument();
textOut[0] = pDoc->m_patName;
if( textOut[0].IsEmpty()) return;
textOut[1] = pDoc->m_patID;
textOut[2] = pDoc->m_imageData[0].m_acqDateTime.Format("%d-%b-%Y");
textOut[3] = pDoc->m_styName;
if( vw->m_masterFlg <= CCardiacView::VW_CARDIAC_DISP2)
textOut[3] = "Myocardial Perfusion";
wnd1 = GetDlgItem(IDC_PATINFO);
pDC = wnd1->GetDC();
sz1 = 0;
for( i=j=0; i< 4; i++) {
sz2 = pDC->GetTextExtent(textOut[i]);
if( sz2.cx > sz1.cx) {
sz1 = sz2;
j = i; // j will be the maximum string
}
}
wnd1->GetClientRect(&rc1);
wnd1->SetWindowText(textOut[0] + "\r\n" + textOut[1] +
"\r\n" + textOut[2] + "\r\n" + textOut[3]);
sz1.cx = rc1.right;
sz1.cy = rc1.bottom;
while( fontSize > 80) {
hFont.CreatePointFont( fontSize, "Ariel", pDC);
hOldFont = pDC->SelectObject( &hFont);
sz2 = pDC->GetTextExtent(textOut[j]); // the longest one
if( sz2.cx <= sz1.cx) break; // found a size
pDC->SelectObject( hOldFont);
DeleteObject( hFont);
hFont.Detach();
fontSize -= 20; // reduce font size by 2
}
wnd1->SetFont(&hFont);
hFont.Detach();
ReleaseDC(pDC);
}
I have a question about DeleteObject(hFont). Do I need it in my loop if I use hFont.Detach()? I noticed you didn't use it in your example, so I also didn't use it when I found the font I wanted. Will I add garbage if I change the patient to a new patient?
Thanks again,
Ilan

double (*pf)(int);
double *pf(int);
I don't understand, how are they difference?
|
|
|
|
|
first is function pointer
second method is returning the double *
first is pointer to function whoes return type is double and argument type is int which refers in code segment
oter method have its return type of pointer of type double
second is same as above
|
|
|
|
|
double (*pf)(int);
this declares pf as a pointer fo a function which gets an int parameter, and returns a double.
such a variable can be used like this :
double Foo(int i) { return (double) i; }
double (*pf)(int);
pf = &Foo;
double d = pf(4);
double *pf(int);
this declares a function called pf getting an int parameter and returning a pointer to a double (double*).
you can use it like this :
double* pf(int);
double* pd = pf(4);
double twice = (*pd) * 2;

Where are you doing that ? If it is outside of the OnPaint (or OnDraw, I don't remember) function, then of course everything will be lost when the window is redrawn. Put all your drawing code ALWAYS in this function.

Hello. I am new to Visual C++.
I am doing a computer control software to control a receiver and i need to capture the signal and plot it out.
May I know which MFC class library is suitable to do graph plotting?? As far as i know there are MsChart control and CGraph class libray...what are the differences in these two?? Are both applicable in Visual C++??
I tried to find the download source for both of these class libray ..Is there any download link for all the MFC class library?? thanks in advance.

I also redirect people on your charting control, Cedric. It is really good.

This description is from MSDN , have you tried this,
Error Message:
Not enough storage is available to process this command.
User Action:
Do one of the following, then retry the command:
(1) reduce the number of running programs;
(2) remove unwanted files from the disk the paging file is on and restart the system;
(3) check the paging file disk for an I/O error; or
(4) install additional memory in your system.

I was facing the similar problem.Is the MapViewOfFile fails first time itself?.If its not then u have to UnMap the Previous view then u have to Map it once again.For this u can use the same handle ,which u got from CreateFileMapping.

You should capture WM_POWERBROADCAST message[^].
Also look at this[^]
I hope it helps,

I doubt. Remark section of this message states ,
"The message is broadcast by the power-management driver to each window returned by the EnumWindows function."

I want to extract the first word (i.e) one .I tried Right,Left,Mid but i could not get the correct word.
P.S: the number of characters in the string may vary to different length.But i need to extract first word that is characters which are appear before a single space.
Any function to extract this?

You could use str.Find(' ');
It will return an int.
Like:
int n = str.Find(' ');<br />
CString strFirst = str.Left(n);
this is this.
