• Game Technologies: DirectX, XNA, XACT, etc. what if we have non-express version of C#?

  I have the professional edition of C#. When I attempt to install XNA framework, I get a message saying something to the effect of "installation failed... you need to have C# express edition installed". This seems a little funny, since I paid quite a bit of money for the pro edition, and I'm thinking it should have the same functionality (if not more). Anyone know what the deal is with this Thanks, PL The Express IDE works a bit differently than the non-Express IDE, thus the requirement for the Express version with GSE, if you want all the functionality of GSE. You can use XNA with VS Pro (after installing C# Express, then GSE, then uninstalling C# Express) but you'll lose a lot of f ...Show All

• SQL Server Interactive sorting of a list

  I have a list data region that has column headings outside the list. I would like to be able to click a column heading and sort the list. However I cannot do this because the scope of the header can't access the list. Has anyone sorted a list by clicking textbox column headings Please help. Hi Patrick- In general, when applying a user sort, you can sort items that are at the same scope, or are in a child scope. You might try setting the textbox to sort on the data set wihch the list is using, and then set the sort expression scope to details. If you are using RS 2005, I've included a sample RDL below. Just copy the text to a file, rename the extension to .rdl and open it in report designer. -Jon ...Show All

• Visual Studio VSS 2005: Require Secure Communications using SSL is grayed out

  I am having some issues setting up VSS Internet access. Has anyone run into the issue where the "Require Secure Communcations over SSL" is grayed out. I have already created, issued and applied a SSL cert to my Default Web Site. I have searched all over the web and the documentation doesn't seem to point to this occurrence. Any ideas See link for the screenshot. http://test.naturalproduct.us/images/vss.jpg Like you say above, localhost does not seem to resolve for me for some reason. This is very strange.... I checked my hosts file and it even has an entry for 127.0.0.1 (localhost). The whole reason I am trying to enable this is so that I can only require VSS usernames when a user connects to ...Show All

• Visual Studio How to get list of files in a solution?

  How can I get a list of all files on which a solution depends By this, I mean all the files which would be required to build the solution on another, new, machine. I'd prefer a method that can create a file containing the list of files. Perhaps a makefile would have this information. Hi, This is an article I wrote that uses a method GetCurrentIDE which returns a reference to the IDE object. From here you can go to the projects and there files. http://geertverhoeven.blogspot.com/2006/12/reference-to-calling-visual-studio-2005.html Greetz, Geert Geert Verhoeven Consultant @ Ausy Belgium My Personal Blog ...Show All

• SQL Server SSAS 2005 Tutorials on Named Instances

  FWIW, this "DOH! moment" may help others who may have experienced the same problems. I have been running the SSAS 2005 tutorials, where my SSAS and SSDB servers are named instances, instead of the default "localhost". The SSAS tutorial consists of a number of tutorials (lessons), each with a project representing the "school solution from previous lessons. Every time I went to load up another tutorial project (lesson), I had to deal with the named instance issue. I kept having deployment errors (32, to be precise, the first two of which told the story): Error 1 OLE DB error: OLE DB or ODBC error: Login timeout expired; HYT00; An error has occurred while establishing a connection to the server.

  Help badly need to resolve a weird issue related to COM IDL (and possibly VC++2005/ATL 8.0's attribute handling as well) I must support a legacy COM interface.
