  Has anyone used the "DBCC SHRINKDATABASE " in a VB.NET project to shrink a DB. If YES, Please, if you dont mind, paste the code in this forum. Tnx Just call it from a command object and it will work. This is from memory so double check the syntax, you will need to add exception handling.

• Windows Forms Event firing in DataGridView DataGridViewComboBoxCells

  I have a DataViewGrid (virtual) to which I have added a row of DataGridViewComboBoxCells. My problem is that when one of the DataGridViewComboBoxCells is dropped downand you click on any of the other DataGridViewComboBoxCells in the same row then no event appears to fire. The drop down closes but the edit does not move to the combobox you clicked on. This problem only occurs if the first combobox is dropped down and you try to navigate with a mouse click. If the current box is not dropped down then the click navigates to the correct box. Navigating with the tab works whether the first box is dropped down or not. Can someone tell me what e ...Show All

• Visual Studio Team System How to refresh VS2005 workitem cache?

  When I have already opened a WorkItem and somebody has altered it I get an error when trying to save. But closing and reopening doesn't cut it. It has cached the workitem. After a few minutes it seems to refresh the cache, but it is annoying to wait. Are there any ways to manually refresh the cache ( without restarting VS ) Thanks borge3000 My VS2005 (Team Suite Trial ed.) does not contain any Edit->Refresh workitem items, nor does pressing F5 refresh the workitem.

• 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

  I've noticed a number of instances with users not being able to access our P4 application because the Activities menu is consistently unavailable.  I have witnessed this situation myself over several  home broadband connections and the Activity list comes up with the following message: "List of games or activities is temporarily unavailable. Please close and try again later." I initially thought this was due to a restriction on the client machine's network, but this has happened to me in my own home after a recent move.  I've changed nothing...even my provider is the same, but the Activities menu is inaccessible from home. ...Show All
