Thanks Alexs,
Your advice helped me solve the problem: the function was in the file but not declared as a member function.
Thanks for taking the trouble to help me.

Hi,
i have two dialog boxes, how do i access a member variable of one dialog box from the other one.The first one is closed using EndDialog and the next dialog box is made to pop up using DoModal();
Thanks

Dialog A should have a pointer to dialog B. In dialog B, provide accessor/mutator methods to manipulate its members. Then do something like this in dialog A.
ASSERT (pDialogB != NULL);
int foo = pDialogB->getFoo();
...
pDialogB->setFoo (foo);

Hi,
How can I develop an Active X control, dialog based with some MFC controls (CEdit, CButton, CStatic) and some Active X controls (extern).
In the Wizzard, I just make an active x control wich subclass BUTTON or STATIC or SCROLL, but I want to integrate many controls.
thank you.

Hi,
I use the ofstream.write (......) function in my code to generate log files from Ethernet traffic. Everything works fine but if I "Stop" my application, the last data is not being sent to the log file but will remain buffered somehow and show up in the log only after I use the close() method.
To prevent that I used the flush() method when I "stop" my application (before closing the files)
My question is,
Is there a way to force the ofstream to automatically flush the buffer to the file whenever I specify the write function?
Thanks,
Shay

It looks like the control can't be created - perhaps the OCX been deleted/moved from the problem machine?

I have an HP DesignJet 5500PS which has WEB pages built into the printer that lets the user control setup and view job status, material status, etc. Having never done any HTML or WEB design or access work in the pass I would like to access the different WEB pages from a program not just to view but to also acquire different fields of information and maybe even change fields from a program.
I have taken the source code (HTMLCTRL) provide on a number of different sources an implemented a dialog where I can view the WEB pages but now I want to actually access some of the data on those WEB pages. Remember I can’t change any of the printers WEB pages, only the code I write. So if anyone can give me some direction as to “how to” I would appreciate it.
NO .NET or VB Please, just Windows, C++ and MFC
Many thanks in advance

I had a problem a while back using STL. I had some code that used the old fashion CTypedArray etc. and I included some STL code. I started getting all sorts of conflicts with <fstream.h> and <fstream>. The new STL code used namespace std and the others did not use a namespaces. There were significant differences between the old fstream.h and the templated one. How do you resolve this with a one or two line configuration?

Post a specific example of the code and what you want to accomplish.

I don' have no code suh'. If I did it would fill the message buffer on CP pretty darn quick. Think big big project.
My question is: What is it in namespaces or use of STL in general that would cause conflict with the use of old fashion <fstream.h>. I tried replacing all the <fstream.h>'s with <fstream> (the STL version) There are some differences in the member functions, I tried to scope the namespace properly and it still didn't work.

Hi,
Can someone explain me or has a class for a small ComboBox ?
I would like to have a ComboBox with a little Edit Box, a small button, a small scroll button,...
Like in these exemples :
http://www.codeproject.com/listctrl/xlistctrl.asp
http://www.codeproject.com/docking/ToolbarWithCombo.asp
I tried to understand these prog, but can't understand !
(Sorry, I'm just a student !)
Thanks a lot.

The height of the button on a combo box (and the minimum height of the box as a whole) is determined by the size of the font used to draw text in the comb. Change the font to a smaller one & you get a smaller combo box.

thanks,
wow, it seems so easy !!!
but I've tried and don't know how to do that.
I've done :
CFont f;
f.CreatePointFont(80,"Arial");
m_cbTest.SetFont(&f);
But it doesn't work.
Can you help me again ?

Two things - first, make sure the CFont object is a member variable of your dialog class, not a local variable (else it'll be deleted when it goes out of scope). Second, an 80pt Arial font is probably large enough you won't notice the change... Besides, you probably aren't sizing your controls in points anyway. Try this, adjust as necessary:
m_font.CreateFont(-8,0,0,0,0,0,0,0,0,0,0,0,0,"Arial");
This will create a font with a total height of 8 pixels - the combo box will be slightly larger because of borders and such.

Hi, I need some help, I'm trying to make a function that fills the length of some string with 0 at left, the function receives two parameters, the string, and the desired length, but when I compile it, appears an error, the error C2440 cannot convert from 'class CString' to 'int'
-------------------------------------
Here is my function:
CSValidating::fill(CString a, int b)<br />
{<br />
CString filled;<br />
filled = a;<br />
while (filled.GetLength() < b)<br />
filled = "0" + filled;<br />
<br />
return filled;<br />
}
--------------------------------------
I would appreciatte if someone can help me to solve this error...
thnxz

Try declaring retuned value as CString or CString&

CSValidating::fill(CString a, int b)
should read something like:
CString CSValidating::fill(CString a, int b)
C++ functions return int by default if you don't specify the return type, so the conversion error is referring to the return filled;
I would suggest that you can improve on that algorithm somewhat too - the hint is that CString has a constructor that can take a character ('0') and a number (something like b - filled.GetLength()) indicating how many times to repeat it

You may have to reverse the order of "0" and filled. I think I recall that there is no overloaded "+" for const char* + CString
And probly better to pass as a reference rather than replicating the CString twice.

As the others pointed out, you are returning an int - probably without knowing it.;P
You definitely need to return a CString, not CString& or *CString. You cannot return anything local to your function, as it needs to exist after your function has terminated.
Your first parameter should be a const CString&: As you are only ever reading it, so you can promise that to the compiler and let it optimize your code. It should be a reference, as there is no point in making a temporary copy of the CString just for this call (as the normal call-by-value does). Yes, I know about CString doing refernce counting, but this is beginner level.
Third, your variable names could be longer and more 'telling' about their use. But that is purely personal style.

Hi,
In my application i have this:
HBITMAP hImage;
hImage = (HBITMAP)::LoadImage (AfxGetInstanceHandle(), "c:\\TEMP.bmp", IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE |LR_CREATEDIBSECTION );
DeleteObject(hImage);
These statement will increase the memory usage by 28 KB.
Size of the "temp.bmp" file is 360KB.
Could any one tell me why is it so?
Regards
