Thanks for your helping,

First of all when I set my first form, it starts automatcly that I included some basic info, I donthave problem with that, my problem is when I add additional forms to communicatate my databases.

IDD_FORMVIEW is the default name, for my test project not the template.

Best regards

Forms should not be communicating with the database. The contents of the database should be stored in the document, which in turn, is displayed by the view. For example, the document could store several different CRecordset-derived objects. When the document is updated, it simply calls UpdateAllViews(), letting each view know that new information in the document needs to be displayed. Each of the views would be in charge of communicating with the document about what it is that needs to be displayed. Make sense?

Thanks again,

So you mean there is no way that VC++ 6 can display form or dialog as a child.

If that is the case I have to back to my visual basic which more flexible in this matter.

Thanks a lot again.

My best wishes

What do you mean by "as a child?"

So does that imply that you know what the answer is since you claim it is not difficult? Asking the right question goes a long way towards receiving the right answer.

Ok, so what part of this is troubling you? Why do you keep mentioning a "dialog?" What you want is one CMDIFrameWnd window that contains four CMDIChildWnd windows. By default, you get one of each. Knowing how the framework creates the initial one should aid you in creating the other three. You'll need to create three more instances of CMultiDocTemplate and call AddDocTemplate(). See here for more.

You can get more information about the error by checking status information returned in IoStatusBlock.

for enable or disable Scrollbar use
EnableScrollBar( SB_BOTH,ESB_DISABLE_BOTH);
and I think for show or hide use
ShowScrollBar(SB_BOTH,FALSE);

and you have splitter or you want to create splitter

for loop incrementing

can a FOr loop be incremented twice at a time?
such as for(i=1; i<=100;i+2)..
as i need to have only odd numbers. Is it correct?

Hello chaitanya
for(inintializer;condition;incrementer)

Here in place of incrementer you can put any statement regards of assigment statement.

It is not require that you use only a variable that is use in initializer place. C design a very rich for loop as you never seen before.

You can even have multiple items in your loop, such as:

for (int i = 2, j = 3; i < 5 && j < 10; i++, j+=3)

If you do not want to make your for loop look anything other than the ordinary, but still want to skip processing the evens, use the continue keyword...

for( i = 1; i <= 100; i++ )<br />
{<br />
   if( i % 2 == 0 ) continue;<br />
   //....<br />
}
