Yes, the fragment is part of a program, which uses scanf with %d, %s and %c, the problem of skipping the scanf function occurs only where the %c parameter is used. Why something is still staying in stdin ??

I have a class derived from CWnd (it looks like a label). I want to set the font but the following has no effect.I tried setting from within the class, and also externally (below). Neither matters.
LOGFONT lf;
memset(&lf, 0, sizeof(LOGFONT));
lf.lfHeight = 6;
strcpy(lf.lfFaceName, "Arial");
m_font.CreateFontIndirect(&lf);
m_grph.SetFont(&m_font);

Does m_font belong to the CWnd-derived class? From where is SetFont() being called? There is an example in the Extras section of this article.

Can you try CreatePointFont??????
The procedure is like this.
// member
CFont m_FontArial;
// Create the font in Constructor
m_FontArial.CreatePointFont( 140, PSIGL_CONTROL_FONT_TYPE_ARIAL );
pWindow->SetFont( &m_FontArial );
yours faithfully

Here is what worked for me:
CClientDC dc(this);
CFont l_font;
l_font.CreateFont(14, 0, 0, 0, FW_NORMAL,
FALSE, FALSE, FALSE, 0, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH | FF_ROMAN, "Times New Roman");
CFont* l_old_font = dc.SelectObject(&l_font); dc.TextOut(50, 50, "Hello World");
dc.SelectObject(l_old_font);
l_font.DeleteObject();
except that I got my CDC in the OnraseBackground function of the CStatic class.
Thanks everyone for helping.

im not sure your problem is this but m_font is global or no i saw if (m_font) isnt global it doesnt work i wrote a program and used like your code but font dosent change then i changed declare my variable from function to class and it worked.

I am wondering if there is any standard convention or guideline to what function should call another. Suppose we have our main() function that will need to call functions setupCalculation() and calculate() in that order. Where should setupCalculation() be called from? Of course if we call it from main(), then we need to call it everytime we want to call calculate(). If we instead call it from calculate() then we may have to pass extra arguments to calculate() that setupCalculation() may require. So, does it come down to a case by case decision, or is there a standard way of going about this? Thanks for help!

No standard that I am aware of. You should strive for loose coupling, however.

If you are making the nested calls ( i Mean calling function inside other function) it grows the stack.
if you call the function seperatly then they have same hiearchy in the stack.
Now efficient way to calling is depends on the Number of paramenters pass and type Vs. Function data.
If Your function work load is large which blocks the parent function in the stack.
For e.g.
void test()
{
while(1)
{
}
};
void mehere()
{
printf("Humm");
test();
};
Here the parent function completes its work but waiting for test() to complete because compiler pops the function data from the stack when it returns and control goes into the parent function.
The point is that you call the functions seperatly which are not related.
As well as it helps to use the stack efficiently for process.

Dear All,
I have alot of old functions that have 'FILE *' as a passing parameter.
Now I am using Compound File...It uses IStream (from IStorage).
Does anybody know how to convert IStream to FILE* ?
Thank's

In general you can't. An IStream is more abstract then a file: while some IStream implementations wrap files most will not.

you can use this(use from ISream only) (of course this is only a suggestion
<br />
IStream *m_StreamFile;<br />
SHCreateStreamOnFile(filename,STGM_READ,&m_StreamFile);<br />

If you are using MFC, try:
CDatabase Db;
Db.OpenEx("DRIVER={SQL Server};SERVER=(local);UID=sa; PWD=", CDatabase::noOdbcDialog);
Db.ExecuteSQL("CREATE DATABASE MyDB");

I am trying to create a color fill that will change relative to a new value being input from the "OnHScroll" function. When I input a new value for the red color variable in the RGB function and re-display, the color never changes to the new value. See code segment below. How do I change?
...
...
int a=0,b=190,c=230,x;
CMainFrame::CMainFrame()
{
//Set color frame
colorbar.CreateSolidBrush(RGB (a, b, c));
};
void CMainFrame::OnPaint()
{
CPaintDC dc(this);
dc.TextOut (5,40,"Red Color Is:");
//Output color frame
colorbar.DeleteObject();
colorbar.CreateSolidBrush(RGB(a,b,c));
dc.SelectObject(colorbar);
CRect rc(100,150,150,200);
dc.Rectangle (&rc);
}
void CMainFrame::OnHScroll(UINT nSBCode, UINT nPos, CWnd* pCtrl)
{
//Convert pointer to slider pointer
CSliderCtrl *pSld;
pSld = (CSliderCtrl*)pCtrl;
//Get new position
x = pSld->GetPos();
a = x;
CString s; s.Format("%d",x);
//Output value for red
stcred.SetWindowText(s);
}
Note that:
1.) Initialize the colorbar to have values RGB(a,b,c)
2.) Variable "a" read in from the "OnHScroll" function and set to a new value.
3.) "OnPaint" deletes the old colorbar and re-creates with new "a" variable value, should display as output with the new color but doesn't, still displays as original a,b,c values. Please advise, Sid kraft sid_kraft@msn.com Thanks in advance, Sid Kraft.

Use InvalidateRect(...) with your colorfill rect as a parameter after stcred.SetWindowText(s); which fires the Onpaint Message and you will get the result
