• SQL Server Updating Table Structures

  Colleagues: When I try to save changes made to tables in SQL Server 2005, I get a time out error about 30 seconds after I initiate the save to the changes made to the table. I then have to back out of the "modify table" operation and I lose my changes.  I never had this problem with SQL Server 2000, even in tables with millions of rows - it would take a while, but I wouldn't get the time out messagand the updates would be saved.  Any ideas as to what's going on Thanks, SMM 29.11.2005 Hi Christian: Thanks for writing - here's the error message I get after initaiting a save of a change to a tab ...Show All

• Visual Basic Modifying App.comfig programmatically from an application

  I am a developer moving up from VB6 to Visual Studio 2005 (VB of course). I really like the concept of the app.config file and want to use it. However, I need to be able to allow users to update the app.config file from the program to change the databases that they are using. For example, I have a multi-company accounting application. I would like to store the connection string for the Database of the first company in the app.config file. I would then like the client to be able to Select the second database from my app and have that written to the app config file. Another example would be a customer that starts out as a single user ...Show All

• Visual Studio Inter-item dependencies

  I have a .targets file that I have created that will take an item list of VcFiles and create a nice archive lib file.  It will also preprocess YaccFiles.  You just specify your items like so: <Project Targets="Build">     <ItemGroup>         <YaccFiles Include="MyParser.y" />         <VcFiles Include="foo.cpp;bar.cpp;baz.c" />     </ItemGroup>     <Import Project="$(MSBuildProjectDirectory)\..\Master.targets" /> </Project> That's really nice and simple.  However, in t ...Show All

• .NET Development convert from double to float...

  OK this has got to be easy, how do I convert from double to float.  I can't figure this out, perhaps a point in the right direction. Thanks, Devin double d = 22; float f = 0; f = ( float )d;   Be careful though there are significant size differences between a double and a float.

• Windows Forms Changing Tooltip text

  I thought I could change the text of a tooltip, just before it's displayed, by handling the tooltip's PopUp event.  After all, it's called just before the tooltip is displayed. However, any changes I make to the text while inside the PopUp event handler appear to take effect after the tooltip is displayed.   For example, suppose the tooltip text is intially "Hello". Inside the tooltip's PopUp handler I change it to "Goodbye".  When the tooltip is finally displayed, it still reads "Hello".  It's not until the next time the tooltip appears that the new text value is displayed. Here's the code I'm running inside the PopUp ...Show All

• Windows Forms Showing a Collection Editor from a Smart Tag

  Hi folks, This must be easy, but I can't find anywhere that explains how to do it. I want to add a Smart Tag to my component which is a LinkLabel that says "Edit Items", just like the ListBox, ListView or TreeView has. My component has a property, for example called "Foos" which is of type List<Foo>. I can bring up the default collection editor from the Properties window, but I'd also like the option of showing this editor from a smart tag. Any pointers I have found the "CollectionEditor" class but can't work out how to show its form for my "Foos" property. ...Show All

• Visual Studio Document Explorer crashes

  Thought I'd start a new thread, since I'm using Visual C# Express, rather than full VS2005. Windows XP Pro SP2, Visual Studio 2003 Pro, SQL Server 2000 Developer Edition, Visual C# Express, Visual Web Developer Express, SQL Express 2005, MSDE. I also have Virtual Server 2005 SP1 beta installed. Problem just started this weekend. Whenever I click on any topic in the Index, Document Explorer crashes. I've tried Repair on Visual C# Express, Visual Web Developer Express and MSDN 2005 Express. Same problem. It was working fine last week, I'm not sure what's changed. I have previously had VS2005 beta2 installed, but I removed that by following the ...Show All
