I am trying to Trap a Windows Dialog that appears when a user exists PowerPoint and the system asks to save changes. The changes are not required and we don't want the dialog appearing.
We have managed to get the handle to the window and pass it the correct key to close the window but still have the window appearing for a second and the Window Beep sounding.
Is it possible to Catch this window and process it before it is displayed and the Beep sounds?

When the PP document is read-only, I expect PP won't let you change it and won't ask such question.

Hi Thanks for the reply.
I am are targeting both Office 2003 and Office 2007.
I have managed a bit of a workaround.
We are giving the user the option to save changes by default of not.
If Save Changes is set we add the following to the SlideShowEnd Event.
CurrentPresentation.Save();
If not we use
CurrentPresentation.Close();
Application.Quit();
This seems to work well although when PowerPoint closes and the changes have not been saved and the show is being run from an open application as opposed to being run from a folder with (Right Click Show) the Save Changes dialog appears. We have managed to get a handle to this Dialog and pass it a "No" key press. The problem is that the dialog still appears for a second with a system beep. Would be nice to handle this more effectively. i.e trap it and action it to stop it appearing.

when the window created, it will show . you can't stop it.
but you can consider this.
1) if you can get the handle of the window,
why not monitor the messages of the window queue,
one window created, message must send out.
so pop this message from the queue, will success to stop window showing.
2) or you can 'hook' the function which create window in Win API.

Hi.
I'm developing a small Windows forms application on which I must apply logon security. I need to verify that the user exist in the AD, is part of a certain group and has the proper role.
I also need to take care of the fact that the computer might not be connected to the network hence no contact with the domain controller.
Does anyone have an idea on how to implement this in a simple way?

Well, use base credentials. Once the computer is connected to the network cache the credential to the client, and use it until the next login to server. Get Roles, groups etc data of that particular user which is connected through login to the local cache (might be in database) and use it until it gets online to network again.

Allright, but how do I do this (I'm fairly new to C#). Is there some examples out there which I can take a peek at?

Reply:
if you use 'socket' or other 'object'...,i think they always have a function like 'connect';
try like this way:
try
{
sokcet.connect();
}
catch
{
// not success.
// deal it.
}

Searching for 2 weeks you must have encountered Directory.GetFiles() and FileSystemWatcher many times, and have become an expert in using them.

yes came across them many times but every time i tried to use them i got errors

That depends on where you search.
|
|
|
|
|
Google is a great place however even that doesn't always give you what you want in a format you understand, everyone got to ask to learn
kenny

Well, you just have to know WHAT to ask of Google and HOW to ask it. This is where the most important skill as a programmer comes into play. It's not the ability to write code or understand the language. It's the ability to do research and teach yourself.

why, high and low, of course.

use
string[] files = Directory.GetFiles("path", "*.avi");
Path represents the path of the directory, in your case its C:\video

Didn't think asking a simple question was such a big deal!
|

The question itself is not a problem, assuming you are willing to learn and make an effort.
And if you want to be spoon fed all your life, that is your choice. No big deal except for yourself.

Very easy.
C# 'FileSystemWatcher' object can help you.
//for example
FileSystemWatcher p = new FileSystemWatcher(@"c:\video");
p.EnableRaisingEvents = true;
p.IncludeSubdirectories = true;
p.Changed+=new FileSystemEventHandler(p_Changed);
p.Created+=new FileSystemEventHandler(p_Created);
p.Deleted+=new FileSystemEventHandler(p_Deleted);

Hello
i am reading article about data access
it have the below code
public DataServiceBase() : this(null) { }
public DataServiceBase(IDbTransaction txn)
{
if (txn == null)
{
_isOwner = true;
}
else
{
_isOwner = false;
_txn = (SqlTransaction)txn;
}
}
the autor comment than the first constructor simply calls the second constructor and passes in null for the transaction.
some can help me tranlate to vb
i test translate web but dont work
thanks for the time

Hope this works ...
Public Sub New()
Me.New(Nothing)
End Sub
Public Sub New(ByVal txn as IDbTransaction)
If txt is nothing then
_isOwner = true
Else
_isOwner = false
_txn = DirectCast(txn, SqlTransaction)
End If
End Sub
