If you want to do that by your own program, you should use client/server applications which should run on both computers.

From your previous posts, this is beyond your current skill level. I suggest learning the basics of VB.NET and the .NET Framework before attempting to tackle a client/server app. A guide to posting questions on CodeProject[^] Dave Kreskowiak Microsoft MVP Visual Developer - Visual Basic      2006, 2007 GetShortPathName ne0h6-Jun-07 0:17 ne0h 6-Jun-07 0:17  Is there any equivalent available of "GetShortPathName" API in VB.NET? ---------------------------- **** JOB23743 Submitted **** Re: GetShortPathName Christian Graus6-Jun-07 0:32 Christian Graus 6-Jun-07 0:32  You can call any windows API using p/invoke.

With the lack of detail you've supplied in your question and not code sample where the error occurs, this is about the most anyone can tell you. Oh, this looks like an ASP.NET app or something that was NOT written in VB.NET. True?

Your best source of information is going to be the site that deals with that library specifically. But, I don't see a support forum on http://www.ikvm.net/[^]. Actually, I don't see much in the way of a support forum at all for it. About the best you're going to do is to post something on it's SourceForge page, here[^].

At the moment I can get the folder that the activeExplorer is looking at and so can determine if a message is in the inbox. However when the NewInspector event is fired and a window pops up with either incoming mail or an editor to create new mail is there a way to determine which is which programmaticaly? Thanks Dan Re: Determine Outlook message status DanB19835-Jun-07 23:57 DanB1983 5-Jun-07 23:57  Hey In the end did a bit of a bodge but it works - for any one with a similar problem all I do is compare the senderName - if there is one it is received and if there isnt one then I am creating a new message Hope this helps some one Oh and if any one has a better/more foolproof way could they please let me know Thanks Dan Encryption problem Deteroc5-Jun-07 22:54 Deteroc 5-Jun-07 22:54  Hi! I have a problem, I have a vb 2005 application and SQL Server 2000 database. Data from vb forms are transferred to SQL tables. However, I need to protect my data. To prevent other unauthorized users from viewing it anyhow. Thus, I do not know, whether I should encrypt the data through cryptography classes in vb 2005 and then decrypt it when I want to display data in datagrids. Or there are some other ways to encrypt it through SQL server components? Could you please suggest me what will be the right way of protecting my data? Thanks beforehand. Re: Encryption problem Christian Graus5-Jun-07 23:22 Christian Graus 5-Jun-07 23:22  The main way to protect your data, is to write a secure database and make sure that only specific users have access to it, and password protect those accounts. You can also encrypt the data if you want to, and if performance is not a concern.

The first is performance. Encrypting and Decrpyting the data takes a LOT of time and makes using the standard Data classes a nightmare to use. Your Data layer is going to be under tremendous stress doing all that math. This makes you solution not very scalable without massive CPU horsepower. The second is searchability. Storing the data encrypted in the database essentially destroys your ability to use an WHERE clauses, except when specifying match values for P/F key and unencrypted fields. A better suggestion is to learn Windows Server and SQL Server security and apply it appropriately.

If your Windows 2000 Server doesn't have AT LEAST Service Pack 4 installed, SQL Server will not install. I would have though that making sure your server meets the minumum system requirements would be step 1 in the decision to buy SQL Server 2005 Enterprise. After all, that's a lot of money you just shelled out for it. ... or did you?
