• Visual C# Post to the web?

  What would be the best way to go about posting to the web For an example, Commenting someone on Myspace or PMing someone on a forum Any ideas as far as I know you can't really do this, unless you are using some newsreader or something. You can implement a webbrowser control in your application but really would be the same thing as accessing IE to access the forum or something like this. ...Show All

• Windows Forms application not starting

  I have a clickonce application, when one particular user click on the install button, the pre-requisites gets installed but it will not launch the application. When the user click the 'launch' button then also nothing happens. I checked the registry entries and file association for .application and he does have those entries. Could someone give me an idea what could be causing the .application not to run at all Nothing happens when running .application. But no other clients have problem. Anyone run into this problem at all Thanks. I started the task manager and saw nothing happening so I looks like something is blocking .application to be launched from internet. I made the site as the trusted site as well just to make sure i ...Show All

• .NET Development Do I need the Microsoft Jet OLE DB Provider on XP SP2 (MDAC 2.8) via VB?

  Windows XP SP2 implements MDAC 2.8 - which does not include the Microsoft Jet OLE DB Provider. So what will the connection string look like without the provider eg: PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=mydatabase.mdb;Jet OLEDB:Database Password=<pwd> What is the equivalent without the Microsoft Jet OLE DB Provider and without ODBC Yes, the Jet Database Engine Components are installed with SP2 on Windows XP.

• Visual Basic mixing vb6 and vb.net

  I created a .tlb in vb.net. The tlb calls some .net functions from the "system.manager" namespace. In particular, some wmi enums and statuses. I enter into vb6 and create an app that references the .tlb that i created in vb.net. I run it and all works well. I create an install and install it on another machine and that is where i get the "Error 429 cant create object" . Please help as i am having a hard time justifying all the time i am spending on this project. Im sure the answer is a registration issue. I have re-registered 'PStat.tlb' on the destination machine. I have re-installed .net famework on the destination machine. I have registered 'PStat.dll' on the destination machine (just in case) (I think th ...Show All

• SQL Server MDX Calculations Script updates

  I have mdx calculated members defined in my cube calculation script. Is there any tool (other than BI Studio) that would allow a power user (typically a financial controller) to modify formulas for selected calculated members Another option could be to use custom rollup formulas stored in the relational data source and offer a nice front-end for modifying those formulas, but this would require a full process of the cube, where as modifying the calculation script would only require a default process. Any other idea Thanks! Sorry, I am confusing a couple of issue here. The multiple commands in the one script will work, it is when you use multiple MDX scripts that only the first is seen. But you will st ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Vista allows What versions of DirectX?

  (split from http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1221168  to make a new question) It is interesting that you say that because I am testing a VB6 app that was working fine on XP and below but now fails on Vista when it tries to create a DirectX8 object, specifically Set oDX = new DirectX8 throws Error 429, ActiveX failed to create component. Running in XP SP2 compatibility mode does not work either. I would be really grateful if anyone has any ideas on this.  I also tried running the latest DX9 redistributable because I heard that was providing backward compatibility, but to no avail. Thanks. I'm currently searching for a solution to the exact same problem. ...Show All
