Visual Basic Write data in VB.NET to Access using SQL
Okay, I have an Administrator page that is able to create new users. I have a simple adduserform that has a TabControl added in it with a tab for General Info and User Info. Those have quite a few texboxes for input and outside of the TabControl are 3 buttons that are Save, Clear, and Exit. What I want to do is have the Save write the data to my small database that I have for users. If you want to see an example of my screen you can see it here.... http://redbearcustoms.no-ip.info/VB/adduserform.html Yes, I was wondering if there was any way that I could post a picture of my screens without having to link to another site. ...Show All

Audio and Video Development Focused Buttons and State not working.
Code sample below. My buttons are acting kinda screwy. I can activate them by clicking, but they exhibit the focus and active states only when I click. Focus is not happening when I mouse over.

Windows Forms Change second form's selected tabPage in tabControl
Hello, Any advice or suggestions are appreciated! I'm trying to change the selected tabPage in a tabControl in a second form depending on an option chosen in the main form.

SQL Server Custom Data Extension - Designer Extension Could Not Be Loaded
Hi All, I've managed (finally) to get a Custom Data Extension to work in Reporting Services 2005. The next problem I have is that whenever I click on the "data" tab when creating a report (from Visual Studio 2005) an error appears: "The designer extension <ext name> could not be loaded.

Is there some way of getting rid of this error message Such as creating a designer, if so does anyone know how (I don't need the designer to do anything, just not crash) I can still modify the data for the report etc its just annoying that's all. Cheers, Dan. Make sure that you have your data extension registered in the RSReportDesi ...Show All
