• Windows Forms VS 2005 Toolbox Refreshing

  Hi, I have noticed that the toolbox in VS 2005 contains a tab for every projects in my solution that contains a component derived class. During builds of the solutions each of these tabs are being refreshed / rebuild and it can take a little time. Is there anyway of stopping this refresh, or is it a matter of removing the tab from the toolbox Maybe this is a bug that has been fixed post Beta 2 Thanks for your help Graham I have noticed the same thing, and it is very annoying.  I have a lot of User Controls in our various projects and it doubles our build time just by refreshing the Toolbox with ev ...Show All

• .NET Development SQL Server 2000 Questions (Newb)

  I am working on a program for a college class.   It is a system for an auction house (live auction, not eBay style).   I am writing the code in C# using Visual Studio 2005 and our database is a SQL Server 2000 database.   In our previous project we used Access 2003 as our database, so I have a few questions about SQL Server:   If I am going to insert a new record (programmatically), and the Primary Key field is an integer, how do I specify that the PK field should be set to the next integer value (In Access, you didn’t have to specify anything if you selected Autonumber as your datatype for the PK field). Is there ...Show All

• Visual Studio Tools for Office Getting contact information from Outlook and Exchange without security message?

  I am trying to collect all of the user's contacts from Outlook and the public folders in Exchange to display in a Windows form in my application. I have it all working using VB.NET and the Outlook Object model except for one thing - getting the Email addresses. I get the security warning when I attempt to get these addresses. And since the user could have 50,000+ entries in their public Exchange folders, having them hit enter 50,000 times is not an option. I understand that .NET does not support MAPI. I understand the CDOEX requires that the app run on the Exchange server (which it cannot). I understand that .NET does not support CDO 1 ...Show All

• Windows Search Technologies PST

  I have thousands of Mails archived in PST files. Is there a possibiltiy to search also these mails Yes, but open up outlook and then open up at least the top level folder in each .PST file. It seems like the indexer doesn't recognize it until it is opened in Outlook, (perhaps a FileWatcher thing rather than a Sessions.Folder quiz, dunno.) You can check it has found them by using the 'Indexing Status' window, i.e. when I first went back and clicked on a seldom used old PST my 'Items left to scan:' jumped up by a few thousand - a good sign it's found the content to index. ...Show All

• Windows Forms Trouble drawing theme elements transparently

  I'm trying to draw a windows theme element (the window close button, specifically) to an image, and whenever I do, the image has ragged non-transparent bits. I got this code from a sample that didn't do this (it was all owner-drawn, mine draws to an image.)

• SQL Server Can't install Express June CTP?!

  Hey all, I'm trying to install SQL Server 2005 Express June CTP on a windows 2003 Web Edition Server (With SP1). I've had an old version of the .NET 2.0 Framework installed, so I downloaded the one mentioned next to the SQL Express download (this one: http://go.microsoft.com/fwlink/ linkid=48448).

• Visual Studio Express Editions Learning VB and .NET

  Hello... I've invested in Books 24/7 to have access to a lot of IT books to learn various things. I really want to get a good grasp on VB.NET 2005 and ASP.NET 2.0. I have VB.NET 2005 Express and VWD Express and I know enough to be dangerous. But I feel that without practical examples, I am spinning my wheels. Also, the books that I try to use to learn the languages. They end up going off on tangents that I don't want to go on. I like the format of Wrox books but they end up making you play around with examples already coded and I feel that I don't learn anything. Their VB 2005 Pro book has no structure of learning it. So it is either using e ...Show All

• Visual Basic Getting rid of the VB6 MAPI controls in .NET

  Hi, I'm upgrading an app from VB6. I used the MAPI controls in several places. They've upgraded successfully and appear to be working. However I would like to replace them with some pure .NET solution as I'm trying to get rid of all Active X controls. What options are available Regards Michael MAPI is an obsolete technology with respect to .NET and Microsoft doesn't support it in this environment. The MAPI controls to which you refer are COM wrappers for the Simple Messaging API. If you're looking for a native .NET code wrapper for this API you may want to check out the following: Simple MAP ...Show All
