Hi All,

I am faced with a situation where a window from my application needs to handle events the notifications for which are going to another window.

Can someone tell me how I can make my window get the event notification?

More specifically, the issue is regarding the Drag and Drop implementation between my namespace extension and windows explorer. I need my namespace extension to get a notification that a file has been dragged from here and dropped on a particular "Windows Folder".

Thanks in advance,

Regards,
Anil

Dear Sunit5,

My First Target is to custamize the exiting GINA statically. Some one suggested that you can directly modify the existing dialogs by opening it in VC++ Stdio. But I am not able to open the GINA Dialogs in VC++ stdio.
Please let me know How I can achieve it.

2nd Target is to modify GINA dynamically or using another GINA DLL which may be I can achieve by writting GINA DLL as described in "Building and Testing a GINA DLL" in MSDN.

I am using Windows XP.

Thanks and Regards
Manoj

Technically, yes. That is, in a hosted iexplore AciveX. This code can even interact with your C++ code by calling its functions (and vice versa).
Search MSDN for something like "custom menu explorer" (without quotes).

I have a simple calculation method which does not have interaction with Internet Explorer, Events etc. Can I run javascript without Internet Explorer or hosted iexplore ActiveX. Smile | :)

To execute javascript you need a script interpreter. You can get this using the ActiveX script host control. However, this is really intended for embedding scripting into your application and is quite complex to use.

If your method is simple, you'd be better to simply port it to C++. Alternatively, write your application in javascript? What does C++ bring that you need for your application?

It's probably not simple to set it up, but anyway ...

Problem in Deleting a file using 'remove'

Sarvan AL10-Jan-06 21:40

Hi,

I'm facing a problem in deleting a file using 'remove'.Let me explain the scenario.

The dialog based application has four dialogs in the following manner:In the main screen, if a button is clicked, the second dialog opens; from the second dialog third dialog gets opened, and so on.

The application deals with a file (say 'test.dat' - has objects of a class) in the fourth dialog. The file operations are: add, modify and delete objects.

An object is deleted by creating a temporary file using the 'test.dat' omitting the object to be deleted; the 'test.dat' is deleted using 'remove' function; the temporary file is renamed as 'test.dat' using 'rename' function.

First time the 'remove' function works fine. I am able to add & delete objects so many times. But If I close the fourth dialog and open again from the third dialog, the 'remove' function fails. I am getting the error 'ERROR_SHARING_VIOLATION' in GetLastError. But I have closed 'test.dat' file and the temporary file using 'fclose' function, before try to delete the file. I have opened the file as 'fopen("test.dat", "r")'

Give me your comments.

Thanks in advance.

I can't grasp the exact idea from your description, but the error message suggests the file is still open when you try to delete it.
Try closting the file first. Make sure your destructors are called when you expect them to be etc.

There is a button class in MFC to do just that by drawing the whole thing as a graphic.
See MSDN.

Create A CFont Object with required attribute and attach to the Button variable...

Text color

for that you have to subclass the Button

If using MFC, you have to subclass the CButton control.

This cute article demonstrates the techniques:-

If not using MFC also, you would have to subclass the button control, no
other way Smile | :)

Hi all,

How could I disable the changing of column width in a listctrl?
In my program the changing of column width of first column should not be allowed.

Thank you.

HDN_BEGINTRACK

Returns FALSE to allow tracking of the divider, or TRUE to prevent tracking.

lParam has a pointer to an NMHEADER structure that contains information about the header control and the item whose divider is to be dragged.

But if you want to do it the easiest way do this:-

m_myListCtrl.GetHeaderCtrl()->EnableWindow(FALSE);

And I hope you know what EnableWindow(FALSE) does.;)
