CSplitterWnd::SetRowInfo(), CSplitterWnd::SetColumnInfo()
Wow! I looked at them but I didn't really bother reading the info, so my suggestion was to use MoveWindow. Would that work?

No. The sizes are cached in the CSplitterWnd class, so bypassing them would produce errors later on.

Thank you! I'd better delete my reply then.

But it seems that these function only works for the first row.
when I try CSplitterWnd::SetRowInfo(0,10,10) , it works well.
but if I try CSplitterWnd::SetRowInfo(1,10,10),nothing happen
Thanks

Did you call RecalcLayout()?
My opinions may have changed, but not the fact that I am right.

I'm a student. I'm learning windows programming. Now I want to write a wordpad in API and without using edit control. I find there are too much things I must deal with. I'm puzzled.
Would you have something like this. Please give me the sample or source code.
Thank you very much.

I have seen a tutorial on how to write a text editor but the whole thing is in Win32 asm. However, the concepts and functions are the same as in API so have a look at this link [^].

I'm not surprised. Why would you consider writing a text editor without using an edit control?

Good point. Although I've done it  . Edit controls and rich edit controls weren't enough for what I needed, so I wrote my own. Works beautifully 
I certainly wouldn't recommend it without a few years Windows programming experience though. It was a substantial project

Hi! I am new to C++. I want to implement the any size integer class. But I got link error, the vs.net 2003 show this error message:

I didn't really go through your code but I don't think you can assign a number to myi, because LargeInt class doesn't have an assignment operator. LargeInt<60> myi(120) would be the correct syntax (I can't exactly remember how templates work).

Unfortunately that is the right syntax. In C++ "=" operator cannot be override, and LargeInt<60> myi=120 should call
LargeInt< i_size >::LargeInt(int number)
so that i_size=60 and number=120
My code can be compiled, but has link errors.

No offense, but where did you hear that?

Sorry, you are right about that (but only in you case). You must provide copy constructors for more complicated classes.
Your code compiles just fine and I don't have any errors. Actually, this line negative=true?number=-number:; gives errors. But then again, you say that you have no errors. Since I don't have a problem compiling your code I don't know what your problem could be. Try to put everything in one file (remove the include directives that are not needed) and see if it works. If it does work then there something wrong with your header declarations.

Well,I got to know that "=" cannot be override in MSDN April 2003 CDs.
It's table says:
=, ., ?:, ->, new, is, sizeof, typeof These operators cannot be overloaded.
and the artical's title is "operator overloading, overloadable operators"
Please take a look!
I said vs.net 2003 can compile my code, but have link errors.

const CString& operator =(
const CString& stringSrc );
const CString& operator =(
TCHAR ch );
const CString& operator =(
char ch );
const CString& operator = (
LPCWSTR lpsz );
const CString& operator =(
LPCSTR lpsz );
const CString& operator =(
const unsigned char* psz );
No operator= overloading you say? this was taken directly from the msdn online help...
A student knows little about a lot.
A professor knows a lot about little.
I know everything about nothing.

Thank you! For a moment I started to believe that the C++ I learned a few years ago, is not the same anymore.

Thank you very much for your correction.
I just got the wrong link of MSDN article,it's "C# Programmer's Reference" not C++.
Thanks again!

Thank you! That works. But how could I do if I do want my implement code saved into the .cpp file?
And
negative=true?number=-number:;
is error, do I have to change it to
if (negative)
number=-number;
I think there is a way to use "? :" instead of "if"
Thank you!

Thanks!
But does it mean that I have to ship out all my code to the template class user?
Is there any way to hide the implementation code?
Thank you!

Yes, you do if they are to use any of your templates. You can have templates in your cpp file no one uses the template outside of the .cpp file.
