How can i use the Dynamic Data Exchange with the combo box.
I just want to initialize my combox box with an element at
index 0.
Is it possible by DDX to restore the selection done by a user??
thank you

If the control is empty, use AddString(). Otherwise, use InsertString(0, ...).

Hi David
Actully i mean that i wanted to use the
dynamic data exchange.
As for the Edit box we can Initalise & use the variable defined
as the CString by using the Wizard.
To initalise a editbox varibale CString m_passwordvalue
we can add this code to the dialogbox constructor
m_passwordvalue = _T("1");<br />
m_usernamevalue = _T("PMR");<br />
By the DoDataExchange function the data from the edit box is
transfered to the varibale (m_passwordvalue) on doing
UpdateData(FALSE)in any of our functions ;
<br />
void LoginBox::DoDataExchange(CDataExchange* pDX)<br />
{<br />
CDialog::DoDataExchange(pDX);<br />
DDX_Control(pDX, IDC_PASSWORD, m_password);<br />
DDX_Control(pDX, IDC_USERNAME, m_username);<br />
}
I wanted to use the same fundamental for the ComboBox is it
possible ???

Anything is possible, but the bigger question is why would you want to? Populating listboxes and comboboxes using DDX is just kludgy.

hum, if i remember well, i've already seen such a thing when i was hardusing my TI-89 calculator. i believe that the sources can still be found on the web as they are free...
see on Leiber[^] web site, and on this library[^] in particuliar. search in the zip for flib2.c and look for the string "komp:" in the file to see the algorithm in C.
for assembly code, see in this[^] zip file.
it may be assembly for Motorola 68k, but hey, that's already a big code, isn't it ?!

Hello,
I am setting maximum length of the Edit box as 36 bytes using the API SetLimitText(36).
Since each japanese character is 2 byte long, it should accept only 18 japanese characters.
But in case Japanese XP OS only, it is accepting 36 japanese characters instead of 18 japanese characters.This happens only in Japanese XP.In other OS's the same character is used and it is accepting only 18 japanese characters.
Please provide some solution for this problem.
Thank you,
Shiva

Which implies ANSI.

Are you re-compiling the code for each environment, or is the same .exe being used for each?

Hi,
Thanks for your reply.
We are using a single .exe. In the project settings->process definitions shows we are using _MBCS.

HELLO!!!!!
I am working on an MFC application. On execeting the program it is not giving any errors. But, on clicking on a the command button, it gives error message,"Run Time Error!! The program has requested runtime to terminate in an unusual way"
What should i do, to remove it? I had not called abort anywhere in my program. Please help me.
Thanx a lot

It happens because an unexpected error occured in your program (it is a bug).

That is really simple: remove the bug  .
Without seing code, it is impossible to help you. Post the code where the problem occur (use the code tag to format the text correctly). Did you use the debugger also to see where your program crashes ? (Press F5 to start the debugger).

Hello!
When I debugged my program, it is giving the following message:
"Unhandled exception in PracticeINI2XML.exe(KERNEL32.DLL): 0xe06d7363:Microsoft C++ Exception. "
Also in the Output Window it is giving message:
"no matching symbolic information found" against kernel32.dll and gdi32.dll.
how to remove the bug now??

Find and open the stack window in Visual Studio when the program has terminated. Follow the function calls on the stack until you find a function in your program. And there you can find the cause of the problem.

That is normal, don't pay attention on that.

Ok, but in which file is the problem occuring ? Try to use the debugger correctly, that is setting breakpoints (F9) at precise points of your program. You said that this error hapenned when you press a button then you can put a breakpoint in the function and go step by step in the program to see where it crashes. You could also post HERE the code of the function (only the code of the funcion and using the code tags).
And please, don't send private mails with source files as I don't have Visual studio installed on my computer. So I cannot test your program. You'll have to be more precise in your question (I cannot go into all of your files and read everything).

Hi
I have developed the dialogbased MFC application and in that I want to print a text a marquee. i.e it scrolls from right to left horizontally.
For this i have used a timer control and on every few ticks I am showing my text by TextOut() functions at one pixel or few pixels ahead of last time.
But here when I use large font size i.e of 200 or like that, it gives me more flickering.....and also it moves bit slowly....is there a way to remove flickering and moving text fast....
Thankx in advnce

This the problem. I suggest you should use some backbuffering here. This needs two draw spaces : One that is displayed, and one on which you draw your text, and you swap them "every few ticks".
For this, I recommand showing at CMemDC (search for this on Codeproject).

First of all since you are using a dialog base application, I suggest you not to use DrawText. Rather you can use any Level control to put display the text. And you can Invalidate the Level control in regular interval.

I am getting some unknown errors with string length function.
|
|
|
|
|
Please, be more specific.
What's the error? What does your code look like?
What kind of "string" are you referring to?
|
|
|
|

are u talking about CString::GetLengt() ?
