thanks, David.

I need that 0 because it's the phone number, 0123 is different as 123 in some country's city code.......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.

CEdit ctrl-c, ctrl-v doesn't work on a CFormView derived window

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 Blush | :O

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? Unsure | :~

SDI/MDI interface

When you create an MFC project, you may choose between an SDI, MDI or Dialog-based. In Dialog-based, we can create buttons, lines, and other controls but in SDI, you have to insert a dialog to place your buttons, etc.
I would like to ask if it is possible to place these dialogs, edit boxes, static text, etc to the main window of the SDI or MDI? if yes, how, just a snippet will do? Thanx Smile | :)

Yes, when creating your project, on the last step of the creation wizzard, you can choose from which class view (CView, CScrollView, CFormView,...) your main view class will inherits of. Just choose CFormView and a form will already be ready for you. You just need to place the controls you want on it.

No code snippet necessary Wink | ;)

DWORD buff;
TCHAR *szBuffer = NULL;

HANDLE hr = CreateFile(L"c:\\a.txt",FILE_READ_DATA,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);

ReadFile(hr,&szBuffer,10,&buff,NULL);

If you are opening Text File why Not go for CStdioFile and CFile class.. Thats work well with The Text or binay file!...

No

The reason is ReadFile doesnot allocate memory for szBuffer .
Use this code

DWORD buff; 
TCHAR szBuffer[SOME_SIZE] ;

HANDLE hr = CreateFile(L"c:\\a.txt",FILE_READ_DATA,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);

ReadFile(hr,szBuffer,SOME_SIZE,&buff,NULL);

Check the second and third parameters. They should be:

ReadFile(hr, szBuffer, sizeof(szBuffer), &buff, NULL);

Playing *.avi files[modified]

Hello guys,
I have a MFC dialog based application , where I want to play *.avi files.
Suppose I have a button "Load video" and after clicking it and choosing the specified *.avi file , I want to be able to play(pause,stop) the video in my dialog.

Any suggestions on how to do it?

PS. I had problems with CAnimateCtrl , When I tried to Open the file :

if(!m_animate.Open("c:\\file.avi"))
   MessageBox("Could not open video");

I got the latter MessageBox. Though file.avi existed on C: disk.

Just a check.
Does file runs in media player?
Do you have necessary rights on file?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
