Are we sure the DLL is COM based?
You may be dealing with a traditional dll here that uses LoadLibrary(). The thread initiator did not specify this unfortunately.

Hello,
When I created a small test file:
<code>
#include <iostream>
using std::cout;
using std::cin;
using std::endl;
int main()
{
int number;
cout << "Enter a number (1 or 2): ";
cin >> number;
if (number != 1 || number != 2)
{
cout << "You didn't enter a 1 or 2" << endl;
}
else
{
cout << number << endl;
}
return 0;
}</code>
The result always "You didn't enter a 1 or 2" no matter what number was entered. I tried changing the code to:
<code>
if ((number != 1) || (number != 2))
</code>
with the same results. Any clues? Thanks in advance.

Try writing a truth table for this and see what the result is  . You'll find that the result is always true. What you actually want is if (number != 1 && number != 2)

Hi guys,
I am using isinf() function in my program. But in VC++ it is giving me the error "isinf undefined identifier". Does anybody know how to make isinf() function work in VC++?
Thank you very much.

_fpclass
bool isinf(double d)
{
int fpc = _fpclass(d);
return fpc == _FPCLASS_NINF || fpc == _FPCLASS_PINF;
}

What peterchen is (probably) telling you is that isinf() is not part of the Win32 API, hence the need to make your own.

oh ok...thanks. so there is not easy way to check for infinity in VC++...

Not that I know of, unless you are using the .NET framework.

Then check out the Double.IsInfinity() method.

Hi All,
In VS 6 I copy data from a custom control on a dialog using my own clipboard management (see code below) and would like to paste it into a CEdit on the same dialog. I believe I am getting it to the clipboard correctly, in CF_TEXT format because I can paste the text into WordPad or Notepad just fine. I am unable, however, to paste my clipboard contents to the CEdit either with the CEdit context menu or Ctrl+V. Making this all the more confusing is that if I copy text from Wordpad, which presumably is in CF_TEXT format, I am able to paste into the standard CEdit just fine.
Any ideas would be greatly appreaciated!
Thanks,
Doug

CString strData;
m_list.GetText(m_list.GetCurSel(),strData); m_list is the Control variable of the CListBox Control.

I try to share .pch (precompiled header files) across my library (more than 50) but i failed.
Using VC+ 6.0 is possible to share the .pch file reducing compilation time but when i try this in VC+2005 i ave found a lot of problems...
Can anyone help me?
Tanks and sorry for the poor english...

I suppose you could in theory, assuming the files comprising each project were the same, but are you sure you want to? Why not just let the .pch file get built once for each project and be done with it? Your apt to spend more time trying to 'share' the file than you would just building it for each project.
