If you have to do a lot of processing I suggest you use threads for that so that the event handler exits as soon as possible.

Perhaps it doesn't mean long file name, or hard business, but it worked!!!!!! 
Which internal side are you recommend to init the buffer (I multiplied it - the value before was like 8912...)?
Thanks!!!!!!!

Hi all,
I’m a C++ developer and a very beginner in both C# (.Net) and Word Programming. What my company wants next is something like this: from different texts to build a Word 2007 document and then open this in the real Word 2007 application to give the user the possibility to change the document as usual with all possibilities (Menüs, Panels, etc.). Well my problem is that the Word 2007 must be embedded in our C# - Application (WinForms).
Knows somebody a solution to do this: embed the Word 2007 application in WinForms or if better maybe in WPF? For any idea thank you in advance.
Best Regards,
Emil

I don't think you can embedd it. I do believe you can run/control it, using the Office Toolkit, or whatever they call it.

The interop stuff is pretty straightforward. Look up Microsoft.Interop.Office.Word in google. Anything you can do in MS Word, you can do in C# using the interop libraries. One tip - if you're going down this route - do what you want first in MS Word, recording it as a macro. Then 'edit' the macro. You can almost cut'n'paste the macro code into your C# app.

Like I told you yesterday, C# does not know the file format used for database backups, therefore it cannot restore them unless you know the format well enough to write a decompression algorithm.
If you do, please write an article about it.

Hi,
I have a problem triying to save the mails retrieve from server in a format that outlook can open, i can save in a txt plane format, but i dont know how to save in an outlook format, somebody can help me or tell me any solution? thanks in advance

Out look stores all it's mail in one big monolithic file. Your best bet is probably to read the mail but leave it on the server, so outlook can still retrieve it.

Users should connect to a web page, which show the message their required, im thinking that is not possible do this goal without having outlook install in the server is this correct?

Hi there.
I am trying to create a step by step wizard, for a Windows Mobile 6.0 PDA.
I have used forms as the steps.
In my mainform I have a method that finds the next step from an array. There are three types of steps, and each steps can appear more than once in one session.
When the last step is finished, the first step will be shown again.
In an earlier program, I used panels as my steps, but it was a little difficult to manage each step in the same form window.
In my new version, I am trying to use forms instead, but every time i click next, I can see a short blink, of the programs running in the background.
When i click the next step button in the current step, the following code is used:
mainForm.ShowNextStep();
this.Close();
ShowNextStep finds the next step and use nextStep.ShowDialog();
Is there anything I can do, so i wont see those short blinks, without using panels?

You should use user controls, and place them all on the one form. I guess that's what you mean by panels ?

Hi
I'm developing a small desktop client and I'm using the Offline Application Block. When I run my application (both in Debug and Release mode) in Visual Studio 2005 it works fine, but when I publish my application it won't run. I hope someone out there can point me in the right direction since I'm having a hard time finding a solution.
The error:

Hi,
I created Tic-Tac-Toe game. Hope you might have aware of it. Now, two players can play the game in single system.
I would like to make the game as two players can play in their own systems. Ex,
Player1 plays in System1 and
Player2 plays in System2.
Suppose player1 clicks on first cell, the same move should reflect in system2, dynamically.
Next turn goes to Player2. whenever player2 click on one cell out of nine cells, that should reflect in System1.
Hope you understood. Please guide me how can I synchronise both systems.
Thanks and Regards,
Lalitha
