Any particular error that you are getting when using this API? I've worked on this.

I need to write a debugger which will execute an process and I need to get notification when that process will write or modify any thing on the hard disk. Can we keep watch on any process for getting info when that process will write to hard disk? I have read something about "Win32 Debug API". Can any one guide me or give me any demo code for this?

In short: no.
Slightly longer: yes, but it requires a filter driver that you can connect to from user mode the way Process Monitor by Mark Russinovich[^] does.
Perhaps you are able to use Process Monitor instead of developing something on your own.

Thanks a lot for your reply. I was thinking to build a file system filter driver. What do you think can I keep watch on a process by file system filter driver? According to me, if we load a filter driver, we need to restart the computer. Can we load a filter driver with out rebooting?

The reason why I gave the short answer 'no', is because this way is difficult and there's a big risk for messing up the file system making the machine impossible to boot.
I strongly recommend that you seriously try to find another solution.
In any case, if you continue the filter driver track, I cannot help you.
As for your questions...

Not exactly, you'd have to filter the file accesses from all processes.
You may do the filtering in the driver.

Correct in this case since it's about filtering the file system driver.

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);
m_Edit8.Copy();
m_Edit5.Paste();
}

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. 
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:

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
<br />
EnableMenuItem(6, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);
Is 6 the id of the menu item.
Best Regards

Hello,
Yes I have 6 as the id of the menu item
I have tried
EnableMenuItem(6, MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);
But that did not work
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.

Naveen.R wrote: If you have done the OnCmdMsg as I said earlier
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  ).
Please check the ON_UPDATE_COMMAND_UI is coming in this case.
