The newest version of MSDN Library that still integrates with Visual Studio 6.0 is October 2001. It may still be possible to download this if you're an MSDN subscriber (although not right now as the subscriber download site doesn't seem to be working).
A very out-of-date version of MSDN Library accompanied Visual Studio 6.0 itself (labelled 'MSDN Library for Visual Studio 6.0'). However, this predates Windows 2000 and I would not recommend using it. (It was up-to-date in mid-1998 when Visual Studio 6.0 was released!)

I want to create a Type-Safe Array with CArray of the following structure
struct structProjectFiles {
CStringArray strDescription;
CStringArray strFiles;
DWORD dDataCode;
};
====================================================================
When I am trying to fill the array with the following code i get a C2582 error. Is there any way to overide the problem ?
//somewhere in the code
structProjectFiles pj;
pj.strDescription.Add("Hello");
pj.strFiles.Add("Files");
pj.dDataCode = 0;
m_cProjectFiles.Add(pj); -->Error afxtempl.h(443) : error C2582: 'structProjectFiles' : 'operator =' function is unavailable

You are missing a copy constructor and/or an assignment operator.

Thank you for your reply.
Is that possible to create a constructor or assignment operator to a structure ? I agree with you when a Class is used but what about structures ? Is that possible ?

Hi all
How to display some text in a control which will automatically
adjust it's size according to length of data.

IMHO you have to measure the text width via GetTextExtentPoint32 or similar and then resize the control according to it.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

When the text is set to your control, you can call GetTextExtent to get the size in logical units.
MoveWindow() your control appropriately.

Hi!
I have a dialog which I painted using 'OnEraseBkgnd' function. I placed a CTransparentStatic ctrl (static ctrl with TRANSPARENT BkMode). I wanted to have the same color as dialog background.
I also used:
<br />
HBRUSH CDialList::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) <br />
{<br />
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
if( nCtlColor == CTLCOLOR_STATIC )<br />
{<br />
pDC->SetBkColor(BkClr);<br />
pDC->SetTextColor(TxtClr); <br />
}<br />
return hbr;<br />
}
Where BkClr is what I wanted for static ctrl to be painted, and TxtClr is RGB(0,0,0).
When dialog first appear the static control is not painted (it's gray) but on first text placment it gets back colored but only for text lenght, not hole rectangle!!!
I did everything and still cant get static ctrl to get all backround painted and on it's first appear?
Help please!

P.S.
I tough when setting controls (pDC's) BkMode to TRANSPARENT, control it self's has the color of it's dialog???

No...
this is for the labels you write down, if you want the to appear just the letters or the letters bounded with an square.

I have to compare two double values upto three decimal places.
Is following logic meaningful?
double Value1, value2;
Value1 = 0.54677788888;
Value2 = 0.54700000000;
CString str1,str2;
str1.Format("%.3f",Value1);
str2.Format("%.3f",Value2);
if (str1.Compare(str2) == 0)
output-> After rounding three decimal places values are equal.
else
output-> After rounding three decimal places values are not equal.

Did it work for you or not?
Suggestion to the members:
prefix your main thread subject with [SOLVED] if it is solved.

I need to compare with double value itself.
how do we do it?

oh
got it
i shall work it out and reply.

You can't. Floating-point values cannot be represented exactly on a binary machine. Instead, you'll have to compare the difference to some very small number. For example,
if (fabs(Value1 - Value2) < 0.000001)

This is faster than my solution on any case, but... would it work using the function I wrote below rounding the decimals up to a Nth position?
Or will it give problems because of the internal structure of "double"?
I have just used my function to limit the numbers that had to be updated to the screen, due to place problems, not to do comparisons.

But you are still comparing a double to 0.5 for equality.

Use %.3lf for double, f is for float.

You might want to check the source code of CString::Format(). You'll find something to the contrary. The l prefix has an affect on d, i, o, x, X, u, c, C, s, and S types.

I made this function to use it in my project before doing updates from edits or labels
double CutAndRoundNumberToNDecimals (double dValue, const int nDec)
{ double dTemp = 0, dFract = 0, dInt = 0, dRes = 0;
dTemp = dValue*pow(10,nDec);
dFract = modf (dTemp, &dInt);
if (dFract >= 0.5)
dInt++;
dRes = dInt/pow(10,nDec);
return dRes;
}
