I have a multiline edit control. This control should be populated with strings with each string representing an event information. I want to know how to Set the text without clearing the text which is already populated. So basiclaly I want to concantenate the text here. Is Using GetWindowText (Gets the historical data) and SetWindowText (Historical data + new) suffice.

Yes, if you use CString you can simply do that. Don't forget to add "\r\n" to start a new line.

I saw something like the following:-. Was wondering whether it could be used.

void CEditCtrlTutorialDlg::OnIn() <br />
{<br />
    UpdateData();<br />
    m_Edit8.SetSel(0,-1);        // Select all the text<br />
    m_Edit8.Copy();             // copy text to clipboard<br />
    m_Edit5.Paste();           // paste text from clipboard at caret pos<br />
}

Yes, but why go to all that trouble? Simply use EM_SETSEL to set the insertion point after the last character, and then use EM_REPLACESEL to insert the new text.

You could consider using a list control for this instead, unless you realy want the user to be able to freeform edit your event log. List controls are easier to override for changing the way they look if I remeber rightly it's not hard to make the grid lines disappear for example if you want it to look like a readonly multiline edit. They can contain much more as well I wouldn't try putting 2 million lines of text in an Edit Control, ( I think max is still 64K), but a List Control will be happy with that. Smile | :)

Nothing is exactly what it seems but everything with seems can be unpicked.

For toolbars if you set the CBRS_TOOLTIPS style then toolbars will send TTN_NEEDTEXT notification message to it's parent window. Handle this message to show tooltips.

Hi again, I'm trying to find someone who used Imapi for cd recording if he could help me. I'm having a problem with staging a image for folders to enable burning to cd. I'm using ISorage and IStream, I'm only having trouble with folders(subfolders), no problem recording files! I call my function member 'BurnCD()' for recording, here is the code:

<br />

on the bolded,underlined line is where my code crak's reporting "Insufficient permissions to create stream!"
If someone can help with this or post it's code how to solve storage for folders please do so, I'm very thankful to all who can help!

Hello,

I have a CMenu class object with some menu options.When I try to disable a particular menu option I am not able to do it.I have used the following

EnableMenuItem(6,MF_DISABLED | MF_GRAYED );
But if I use the following
CString R;
GetMenuString(6,R,MF_BYCOMMAND);
I get the particular string of Id 6
What I sould do to disable the menu_id?
Thanks
Prithaa

Use this
and
Set the m_bAutoMenuEnable to FALSE in the constructor of
CMainFrame so no ON_UPDATE_COMMAND_UI or ON_COMMAND handlers are
needed.

If it's an MFC app then you should use ON_UPDATE_COMMAND_UI macro and handle disabling and enabling there.

Hello,

Thanks,
I am not using Doc-View architecture.Yes I am using MFC's in my app.

I am handling enabling disabling in OnCmdMsg() of Mainframe class

Bye.

If you have done the OnCmdMsg as I said earlier, to disable the menu you need to return FALSE from that funtion.

Is this the correct way? ON_UPDATE_COMMAND_UI macro is provided for this purpose right.

When I checked the ON_UPDATE_COMMAND_UI wasn't arriving..

Please try.

Create a menu dynamically
Set it to mainframe using the SetMenu().
Now the menu will be disbaled since it dosent have command handler.
So I stepped into the MFC code and found out that handling the OnCMdMsg() will solve the pblm( I forget what you said in the IPT class D'Oh! | :doh:

).

Please check the ON_UPDATE_COMMAND_UI is coming in this case.

Launch Application after Setup

I created a Setup with Visual Studio and all works nice.

I like to start the application automatically after the setup is closed.
(probably add a new page with the demand to open the app or not )

Has anyone an idea how to start it?

Big thanks
