• Visual Basic Opening New Applications

  I am trying to create an application which can open a web browser and automatically navigate to a certain page. I've already added the line Process.Start( "iexplore.exe" ) How do I make it so it reroutes to a certain adress I know in Command Prompt you can just type something such as " start iexplore.exe www.msn.com " and it will automatically take you there instead of the home page. Can I do this in Visual Basic ...Show All

• Visual Basic File I/O speed in VB.NET vs VB6

  I read and write a large data structure in VB.net as:    FileOpen(1, TheFileName$, OpenMode.Binary, OpenAccess.Write)    FilePut(1, Drawings(DrawingIndex))    FileClose(1) Where Drawings is a Structure and consists of other structures, arrays of arrays etc. In VB.net this is almost 10 times SLOWER than the equivilant from VB6 In other words, the same basic read/write operations seem to take 10 ti ...Show All

• SQL Server SQL2005 Database Schema without Assocated Owner?

  I was quite happy to see that schema names and database users had finally been separated in SQL 2005 and used it to finally clean up a mish-mash database that hosts a number of tiny unrelated applications. I created a new schema for each little section, and the schemas are all owned by dbo. There is no associated user with the schema. Really it all works great... ...except... from an ADP project in Access! If an object is in the dbo schema, or i ...Show All

• Windows Forms Treeview Nodes.Add Problem

  I have a problem when I add a child node. When the tree loads the first time, all the child nodes display correctly.  If I add a child node, it gets saved to the database, and I clear out the tree (treeview.Nodes.Clear) and repopulate it for the new node to show.  However, now the new node I just added, appears in another location and I end up with 2 child nodes with the same name. Any ideas on how to make the treeview refresh cor ...Show All

• Visual Studio 2008 (Pre-release) Vector Image Format for WPF?

  How can I go about creating vector images for use in WPF. I've heard of different XAML export capabilities, but this simply translates the image into XAML markup, which is not a vector image format. Will there be an image format which will be used for vector images in WPF The reason I ask is that it seems rather painful to have to copy/paste the markup for the image into an elements resource section each time I want to make use of that image. I ...Show All

• Windows Forms How can I line up labels with textboxes in a FlowLayoutPanel?

  You know how in the VS2005 you have those grid snap lines, which let you align labels with textboxes in the middle (the pink line) Well flow panel still dumps everything aligned at the topmost corner for each component, and all the labels looks wierd. I could adjust the top padding on each control, but it's a pain, is there an easier way This question is better suited for the Windows Forms forum. Please reser ...Show All

• Visual Studio Team System Mapping between FxCop Rules and .NET Design Guidelines

  Is it planned to implement a mapping between FxCop Rules and the "real" MSDN .NET Design Guidelines (Could be a table on some web page or something in the FxCop CHM). Regards Micha I'll take a look at the updated design guidelines, but I don't believe this information ships in it. We did have notations in the source content for the DG that noted whenever an FxCop rule existed for a specific guideline. ...Show All
