Thanks! 
Using GetTextExtent/TextOut is all very well, but that doesn't tell me how much of my text will fit into a given rectangle. Once I've drawn my clipped text onto the bottom of my page, I need to know where in my text string I need to start drawing on the next page.
(I do use MFC BTW, but I don't think that's relevant.)

Yes, but not directly. GetTextExtent will give you the size required to draw the given text. Knowing where you begin to write the text, you should then be able to say if the text will go outside a given rectangle or not.
IMO? you should use it before drawing. Here's a sample how I use it:
CClientDC dc(this);
CFont *pFont = CFont::FromHandle((HFONT)::GetStockObject(DEFAULT_GUI_FONT));
CFont *pOldFont = dc.SelectObject(pFont);
CRect clientRect;
CSize textSize = dc.GetTextExtent(sTitle);
GetClientRect(&clientRect);
int iWidth = clientRect.Width() - 12;
CString strNewTitle(sTitle);
while(textSize.cx > iWidth){
sTitle = sTitle.Left(sTitle.GetLength() - 1);
strNewTitle = sTitle + _T("...");
textSize = dc.GetTextExtent(strNewTitle);
}

Mmmm. That's what I was afraid I may have to resort to. It's not very efficient for huge chunks of text, which is why I didn't really want to do it this way in the first place (our reports are often very long, with large chunks of text), but I guess I can optimise it by splitting the string up and testing it using a binary method if it's over a certain length. I guess as it's only a problem on Windows 98, I'll just do it this way for that - maybe that'll teach them to use a real(-ish) OS!
Thanks for your time looking at this!
Paul.

Yes, it is probably not very efficient, even if is it plausible it can be improved (using dichotomy seems good, making assumption on font width then on likely text length could perhaps also help).
Limiting this solution to Win98 users, by detecting the OS, could also limit the damage.

Is the problem not occuring on Win95? (I have to deal with this sh*tty OS, some of our customers still use this big bag of #$ù*#.
Also, the problem may come from the implementation of the printer driver on Win9x. Maybe an update of them, with a lot of luck...

Just looked at source for CEditView printing, as suggested by Jack Squirrel in his reply[^], and it seems that MFC uses a similar method, by having a guess, and then adjusting the string until it best fits. They do that for all platforms (MFC doesn't use DrawTextEx anywhere as MFC pre-dates the function). Looks like that's what I'm going to have to do after all  , but at least our customer will be happy!

Yep, avoiding DrawTextEx seems the good thing to do, jack's advice is the good one. I just have a look to CEditView printing too, very interesting. I learned something, there is an undocumented fucntion _AfxClipLine which may be useful sometimes.
Thanks for the feedback!

There's code in the CEditView class that clips/fits text based on a rectangular boundary. Should be a primary function and a couple of helpers - just copy it to your project, tweak it if need be, and away you go.

Mmm. Just looked at that. It uses a method similar to the one I was avoiding  by guessing how many might fit, then decreasing/increasing the length of the string until it fits best. Oh well, looks like that's the way to go.

how do i get the font name used by the system ,or more precisely i need to fill the LOGFONT structure how do i do.
thanx in advance

You can use the ::GetStockObject function.
If using MFC, the code would be
LOGFONT logFont;
CFont *pFont = CFont::FromHandle((HFONT)::GetStockObject(SYSTEM_FONT));
pFont->GetLogFont(&logFont);
HTH,

Is there ant SQL Query for getting table names from Access database.
I used this code but I am getting errors.

CString sDriver = "MICROSOFT ACCESS DRIVER (*.mdb)";
CString sFile= "c:\\mydabase.mdb";
sDsn.Format("ODBC;DRIVER={%s};DSN='MyDsnName';DBQ=%s",sDriver,sFile);
db.Open(NULL,false,false,sDsn);
CRecordset recset(&db);
recset.Open(CRecordset::forwardOnly,sql,CRecordset::dynaset);
CString s=recset.GetTableName();
//int n=recset.GetRecordCount();
MessageBox(s);

Does the database and the DSN exist?

It looks like you are trying to create both a DSN and a DSN-less connection. Why?

What is the value of sql?

Or something else?

I am a newbie to vc++. I did some C 15 years ago... but, normally, I'm a vb.net guy. However, my current job is VC++ and my boss wants me to place a class inside a .h and .cpp file that already has an existing class. I did this fine but when trying to define an instance of this class from another class, it seems invisible even though I have included the .h file.
Here's my code:
file1.h
class Class1
{
// definitions here
};
class Class2
{
// definitions here
};
File1.cpp:
#include "file1.h"
Class1::SomeFunction()
{
}
Class2::AnotherFunction()
{
}
File 2.h
#include "File1.h"
class Class3
{
Class2 cClass2; // not visible.
};
Any ideas?

Are you using namespaces in file1.h ?
What extactly do you mean by 'not visible' ?
Are there some compiler errors ?

No, no namespaces. Boss doesn;t want to use namespaces.
Getting undefined class error when compiling on the line where I am insantiating a new class variable:
Class2 cClass2;

are you sure you're not having trouble with the class name ??
be careful, C/C++ is case sensitive (unlike VB/VB.NET)...
