• Visual Basic array help

  I need help with an array. i have an excel spreadsheet that I'm transferring to a datagrid for viewing and then loading that information into an access database. The one fuction I have takes over 10 minutes loading 2-columns of 7000+ lines into the database. I have 3 other excel spreadsheets that need loading also and will take to long for the whole process. Is there a way I can use an array to load the 7000+ lines into the database I have to manipulate the strings in all the excel sheets and grab a data file to match the string in the excel to the data file and output it into an excel spreadsheet of a different format. But I'm just using the datagrid to make sure they are loading what I need correctly, filtering out unnecessar ...Show All

• Visual Studio 2008 (Pre-release) Bug Report: Serious problem when binding to grouped data.

  I have discovered a problem when binding to a collection view's Groups property. If you bind the ItemsSource of a TabControl or TreeView to the Groups of a view, when you select a tab or navigate the tree (with the Up and Down arrow keys), an exception is thrown. For example, when I select a tab item, an exception is thrown stating that an invalid cast occurred when casting a TabItem to a GroupItem. I checked this out in Reflector and noticed that the ItemContainerGenerator.GetRealizedItemBlockCount method is using a C-style cast, making the assumption that ItemContainerGenerator.RealizedItemBlock.ContainerAt(int) is going to return a GroupItem. I don't see why this assumption should be made. Is there some overriding reason for not allo ...Show All

• Community Chat Using Vista?

  Good idea Joe! Okay, I'll go first.  I'm using Vista RC1 full time now.  The computer seems quieter--doesn't take so many trips to the hard disk for VM paging.  I find going back to XP an unpleasantry, so I think Microsoft is succeeding here. Glass is nice.  I think the performance is what I expected it to be on an Intel Advanced Graphics card (Dell Dimension 9100).  Office 2007 is also pleasant to use, but they stil have some cleanup work to do on their UI. Who else is using Vista   Brian Your right. Its probably not a very good idea. Its dissapointing though. Every time I try to boot into the HDD that I installed vista on, I get an error saying cannot load winloa ...Show All

• Visual C# Visual Studio 2005 - PILE OF ***!

  Hi, Although .NET 2.0 has brought ,any great additions to the .NET family, the IDE for me is the worst part of the experience. 1. The IDE is terribly slow... much slower than it should be. 2. The IDE seems full of bugs. These two problems do not make a good productivity combination. I do not believe Visual Studio 2005 is suitable for enterprise development, where you typically work on large scale solutions consisting of hundreds of projects. The IDE simply chokes on large solutions. Intellisense comes to a grinding halt and solution level configuration changes, such as setting debug/release mode take minutes (2minutes or more per click). The number of crashes of the IDE per day is also pretty high. We have started recordi ...Show All

• Software Development for Windows Vista when exactly the WorkflowPersistenceService.SaveWorkflowInstanceState method invoked?

  in msdn, it says it invoked after Unload Event. And if the UnloadOnIdle set to true, it did! but if the UnloadOnIdel set to false, the WorkflowPersistenceService.SaveWorkflowInstanceState still called sometime i'm not sure before WorkflowRuntime.Completed. But the WorkflowRuntime.WorkflowUnloaded Event DID NOT triggered that time. Why The workflow persistence can kick off the persistence at a couple of points and it is not necessarily only when the UnLoad event occurs. Just as examples - Couple of activities like TransactionScope or WebService Input/Output can also invoke the persistence to happen. This is By-Design for the WFs. Thanks, Kushal. ...Show All

• SQL Server HELP!!! Can not restore database from only back up I have

  I had to transfer my database from one server to another. Both are running SQL 2000. I backed the database up and moved it to the new server however when I try to do a restore I get the following message: The media set for database "xxx' has 2 family members but only 1 are provided. RESTORE DATABASE is terminating abnormally. I did some searching and found a couple of posts that mentioned something about the back up including 2 files. My problem is that the machine I backed this up from crashed when it was shut down and would not reboot so all of the data and the original database do not exist. Is there any hope of restoring this database. It is pretty critical. Thanks, Melissa :-) Her ...Show All

• Software Development for Windows Vista Anyone Get SQL 2005 Dev to install on 5600?

  I tried to set up SQL 2005 Dev on 5600 but no no luck. I know Reporting Services will not install due to incompatability with IIS7 (way to go), but I can't get the ADW db's to attach, I get a not enough disk space error (on a 250 GB HD), and numerous application compatability warnings from Vista. If someone has successfully installed it, how about providing a quick guide Thanks As a followup, I was able to install SQL 2005 Dev with Reporting Services Successfully. Here are the steps I used Install and configure IIS7 as per the KB below http://support.microsoft.com/kb/920201 Run the SQL 2005 Server Setup.exe as Administrator.

  Hello! I have written a report that is being displayed in a table.

Has anybody experienced this TIA! That happened to me and I checked the width of the object that contained the table. In my case, the width of the rectangle that contained my table was way bigger than it should have been. ...Show All
