If you are going to use the media player activeX control in your application you might want to consult the documentation[^]

Hi,
I have created one application in VC++, in that am using one edit box to display the values , i hav created a member variable for that edit box in that defined double datatype. My question is , if i get any exponential value, it is not displaying fully, it displays upto the size of the edit box. is there any way to see the exponential value in the edit box
Thanks,
Balaji S

I think CEdit is not directly support that. You can use %e or %g to format it as string and set as window text to edit control
e.g
float f = 100.234235454;
CString str;<br />
str.Format( "%e", f );<br />
editCtrl.SetWindowText( str );

I think you mean this:
float f = 100.234235454;
CString str;
str.Format("%e", f);
editCtrl.SetWindowText(str);

Okay this one is for the Gurus!
I am trying to open multiple modal dialogs from a parent modal dialog. However, in modal dialogs only one child dialog can be opened at a time under a parent dialog. Therefore, I have to use the applications main window to have multiple modal dialogs opened and use a map to track which dialogs belong to the parent dialog.
How can I get a handle or pointer to the childrens dialog windows to store them in my map (for the parent to track)?
My goal is to close all the parent's children dialogs once the parent's has been closed. And also consistently close them out by calling theDlg->EndDialog(IDOK) when the parent dialog has been closed by clicking "OK" or theDlg->EndDialog(IDCANCEL) when the parent dialog has been closed by clicking "Cancel".

Multiple modal dialogs...so, which is active - there can only be one at a time. Also, once a modal dialog starts, the only way for it to communicate with its parent window is by exiting - it contains its own message loop rather than using its parent window's message loop.
AeJai wrote: My goal is to close all the parent's children dialogs once the parent's has been closed
A parent window cannot be closed if it has spawned a modal dialog.
Just don't do it - 'multiple modal dialogs' is really a synonym for 'modeless dialogs', IMO. You can close the child modeless dialogs by posting WM_CLOSE messages to them, IIRC.

The reason the parent window can be closed is because its parent too is the main window's (i.e., (long)AfxGetMainWnd()->m_hWnd) as well as its children. This allows for all the modal dialogs to open and not continue in the code sequentially until OK or Cancel has been clicked.
I need to open more dialogs from this parent dialog in order to compare and modify values (of the contents). I cannot use modeless dialogs because it continues computing without the user selecting OK or Cancel; it just creates the dialog and will create multiple dialogs of the same type or instance rather. I have been able to reactivate the dialog that has been opened already by using a PropertyFrame pointer.
I cannot just close the dialogs via WM_CLOSE, but should prevent the parent dialog from closing as long as its children dialogs are opened. That too will be as difficult.

I want to transform a modal dialog box into a modeless so I can drag and drop items from the interface in the main window (in a SDI application) into my dialog box. That bit, I can do - I allocate dynamically the dialog box and call CreateWindow. But I don't want the user to be able to click on the menu or the toolbar (or about anywhere actually except a treecontrol where the drag & drop will start from).
Is this achievable without having to add code on every single menu handler?
Thanks in adavance!

In general, you'd use ON_UPDATE_COMMAND_UI handlers to disable the menu commands and associated toolbar buttons. You could have a single handler method to deal with all the menu commands, but you'd have to declare them all in the appropriate message map.

Hi Stuart,
Thanks for this - but I do not want to have to write a handler / or modify existing handlers for every single of them!
|
|
|
|
|
You don't have to - write one method to handle the ON_UPDATE_COMMAND_UI thing, then register that one (ONE) method for all the ON_UPDATE_COMMAND_UI things you need to handle.

Oh - and you can use ON_UPDATE_COMMAND_UI_RANGE[^] to register one handler for multiple command IDs in one go.

Sounds like a user interface that would cause me to close and uninstall that software. Perhaps you should consider a different design?

I wanted to display the time zone set by the system on a dialog in static text.
For example : The time zone in India is (GMT+05:30) Chennai, Kolkata, Mumbai , NewDelhi.
Now if I change it to some other like (GMT+09:00)Osaka, Sapporo, Tokoyo.
Then I want this statement to be appeared after refersh.
Please let me know how can it be possible???
Thanks in Advance

I'm not very clear about your question, but if you want to be notified when the time zone changes, look at WM_TIMECHANGE.

GetTimeZoneInformation will give you the (+900) part - but not the city list.
I suspect that only lives in the common dialog used, so you may be out of luck.

For now i think that can be enough. Can you give me any sample code using that function.
|
|
|
|

Not without reading the documentation page, calling the function, looking at the contents of the TIME_ZONE_INFORMATION.
All of which you can do yourself.
(It's not a function I've used, it's one I found on msdn)

Hi,
I have an xml file which I want to encrypt using Public /Private key encryption technique.
Could any body give info/code snippet or an sample project which has implemented Public Key encryption technique using public and private key pairs which I would use in my project.
Thanks & Regards.
