Hi left a message about subclassing in Visual Studio 2003.
I got a few replies and some were helpful, but some wernt related to VS 2003.
Subclassing in VS6 is pretty easy because of the class wizards ability to bind the new class to the control on the dialog or window.
However in VS 2003 it doesnt have that!
Here is the url for the previous post ->

Thanks Tom

just create two empty text files, type your header code in one, and your implementation in the other. voila!

Ignoring the IDE fluff, it works the same way - you can do it manually using ctrlWrapper.SubclassDlgItem(), or you can just add a DDX_Control() entry to your dialog class's implementation of DoDataExchange().

Hi and thanks for the replies and for calling me a dumbass  (being sarcastic)  .
I'll give two examples of what ive being trying to achieve, for the smartasses.
Firstly, I was trying to derive a PictureBox that could be drawn in easily.
I thought i could derive a static and add OnPaint and give it a device context.
In Visual Basic 6 (my previous language) i could use a text box then use GetDC to draw in it.
Secondly, I was trying to create a NumberBox from a EditBox and catch the WM_CHAR message and only allow Digits. The NumberBox class was derived from the EditBox Class.
Thanks again
Tom

That'll work. Instantiating CPaintDC in an OnPaint handler will give you a DC you can draw onto. You probably also want to implement OnEraseBknd, if only to ensure that nothing extra gets drawn there.

There are a few classes like that already written - do a search on CP. Note that if you only need integers, you can use the ES_NUMBER style and the standard control will take care of it for you.

cool! If i derive my new class from the parent class!
Eg. class CDrawBox : public CStatic or CNumberBox : public CEdit
Do i subclass the Static Picture box on the form using SubClassDlgItem, same goes for the Numberbox. Thanks again

You can, or you can just use MFC's built-in subclassing, which uses DoDataExchange() and DDX_Control to do the same thing. Take a bit of time and look through the demo code for this article:

morning,
when the string got convert to long, it lost the leading zero, could it just be padded back or it should be converted back to string to add the zero? here is the code, sorry, it's java
String t = party.getNumber().getNNxx();
t = rightTrim( t.substring( offset, t.length() ) );
while( t.length() > 0 )
{
long city = ( party.getCityCode() == 0 ? Long.parseLong( t.toString() ) : party.getCityCode() );
t = t.substring( 0, t.length()-1 );
String szCountry = Long.toString( party.getCountry() );
long token = cintCity.find( (long) party.getCountry(), city );
if ( token != cintCity.end() )
{
party.setCityCode( city );
thanks.

I'm not sure why you asked a Java question in a C++ forum.

No. Numbers with leading zeros are for display purposes only. If you had:
char *szNumber = "01234"; and you assigned that to a long via:
long lNumber = atol(szNumber); why would you want lNumber to be equal to 01234 instead of 1234?

thanks, David.
I need that 0 because it's the phone number, 0123 is different as 123.......thanks for your help.

Ok, but how are you using that number? Are you sending it to a modem for dialing purposes?

I think this shouldn't been done as long since it's for display not conculation, leading zero is meaningful at this point.
I could left pad zero in front of string,
long city = ( party.getCityCode() == 0 ? Long.parseLong( t.toString() ) : party.getCityCode() );
String szcity = utils.leftPadZeros( String.valueOf( city ), t.length());
long token = cintCity.find2( szCountry, szcity );
but the whole app is using long for citycode, it might cause problem later on
party.setCityCode( city );
so I was wondering if I could pad zero in front of long....seems like impossible...
thanks, have a good weekend

David's exactly right. No number with actual meaning has leading 0's, unless it's the 0 before the decimal point. The program shouldn't keep track of that, so you'll have to pad that back, if you really want it.

First off, I appologise if this has been answered before. I always perform a thorough search across google, newsgroups and ofcourse codeproject, but alas I can't find what I need this time hence my first post.
I have an application that has many CEdit controls, the ones that are on a CDialog derived window have the context menu and the ctrl-c etc keyboard shortcuts. The ones that are on a CFormView have the context menu but the ctrl-c etc keyboard shortcuts do not work.
And yes I have found Knowledge Base article Q145616 "How to Enable Edit Menu
Commands for Edit Controls" that everyone with this problem gets pointed to, but this is about the global Edit->Copy, Edit-Paste menu items not the keyboard shortcuts for each Edit control.
How do I get this to work? Will subclassing the CEdit control, handling the key presses and replacing all instances of CEdit with my subclasses control work - if so then why on earth doesn't the CEdit control work this way.
Many thanks,
Rincewind

So what exactly is the problem? Are you not able to paste into an edit control using Ctrl+V from the keyboard, Paste from the Edit menu, or Paste from the edit control's context menu?

So you implemented the code in this article to no avail?

I must have read that KB 5 times before but after actually fixing the problem I now understand the KB - DOH. The answer was exactly in that KB I listed, I feel like a right wally now 
Just in case someone else needs it spelt out like I did on this occasion:
1. The app wizard creates accelerator keys for Ctrl-C, Ctrl-V etc.
2. CFormView's (and probably a class a bit higher up), process accelerator keys, whereas CDialog does not
3. Processing an accelerator key (finding a match between the keys you pressed and an entry in the accelerator key table) means the key press is not passed on to child controls - hence the CEdit control never gets the keys
In my case, I wasn't using the accelerators at all, so simply deleting these entries fixed the problem.
Hope my mistake helps someone else!

I need to create a scheduler which does a function (display message) at the specified time. and it should be able to run at the background in the system try. How can i do this.
A link or code snippet will be useful.
I already have a SDI application and i have the display message function in it i need to call at scheduled time and it should be able to minimize to system tray.
Thanks,

Are you sure? Perhaps you want to create a schedule instead. You need to search for the ITaskScheduler, ITask, and ITaskTrigger interfaces. There are some good examples on MSDN.

* first learn how to minimize your application to the system tray.
* Learn how to set timers for a function.
* make a function that compares current time with the scheduled time, if they concide, popup a message.
is that you want?
All these can be found if you search inside CP itself.
