• Visual Studio Tools for Office Unable to install VSTO 2005 on system with only Office 2007

  I have setup a computer with Windows Vista RC1 and Office 2007 Beta2 TR but when I try to install VSTO 2005 it says I have not installed Office 2003 SP2 and refuses to continue. Is there a work around for this Do you have Office 2003 Pro available If so, try installing just Word or Excel from that distribution. Ideally, if you have only VSTO 2005 and not Visual Studio Team System, this would be the order to install applications so that you can build Office 2007 add-ins with VSTO 2005 SE: Office 2003 Professional (at least Word or Excel, but not Outlook) VSTO 2005 Office 2007 (including Outlook) Office 2007 B2TR VSTO 2005 SE ...Show All

• SQL Server Dynamic XSD Schema Location For XML Source

  I want to be able to programmatically set the schema location for an XML source. I first thought it would be a simple task using expressions and variables but it doesn't appear to allow anything in the way of setting it at runtime. Is this possible It does allow it, but you don't set the expression directly on the component. You have to set it on the data-flow that contains the component. Switch back to control-flow and look at expressions of the data-flow. Its self-explanatory from there. -Jamie ...Show All

• Windows Forms RichTextBox.Rtf -include Final Carriage Return?

  For a string with a carriage return at the end: richTextBox2.Text = richTextBox1.Text; //text is copied verbatim with the carriage return richTextBox2.Rtf = richTextBox1.Rtf; //The final carraige return is not copied over Is there a wy to copy Rtf and keep any final return character Carraiage returns anywhere else in the string are fine.

• Game Technologies: DirectX, XNA, XACT, etc. How do I set The PrefferedBackBufferWidth and Height?

  Im learning XNA but it says PrefferedBackBufferWidth isnt a variable, Im trying to set the size of my application to 800 x 600. Thanks In the constructor for your class derived from Game, you should create an instance of the GraphicsDeviceManager class. After creating this instance you can set the preferred back buffer dimensions: public class MyGame : Microsft.Xna.Framework.Game { GraphicsDeviceManager graphics; public MyGame() { this.graphics = new GraphicsDeviceManager(this); this.graphics.PreferredBackBufferWidth = ...whatever you want; ...and so on... this.graphics.ApplyChanges(); } } ...Show All
