• .NET Development Creating a custom MembershipProvider

  I am trying to create a custom membership provider. There is terriable docs on this. I just want to use the login controls to validate username and password from my DB. 1. I am looking of a complete, working sample. SQL is fine as a provider. 2. With the one I wrote, once I click on the login button, the VALIDATEUSER() method does NOT get called. I read that it gets called automaticallly once one clicks the login button. 3. If this all did work, do I need to do any other work on other pages to make sure the user is validated. Do I need to check something or does .NET take care of this and send non authenicated users to my login page ...Show All

• Windows Forms hosted DesignSurface - editing Controls (e.g. ComboBox) => Crash

  I am playing with hosting a designer and I am already quite satisfied with my current test of a hosted designer - except that some controls crash it. I am just hosting a DesignSurface, add a ComboBox from my Toolbox, then click on the glyph for the smart tags, then click the check box "usw data bound items" once to activate. After doing that and leaving the smart editing again, so that this popup box is closing, I cannot enter it again - if I do so the application crashes with a NullPointerException:    at System.ComponentModel.Design.DesignerActionPanel.TextLine.OnParentControlFontChanged(Object sender, EventArgs e ...Show All

  Hello and thank you in advance to anyone that reads this who may be able to shed some light on the problem. Now onto the problem: I have a panel (let's call it panelA) on my Windows form, and I am programmatically adding my own user controls (let's call the user control class myUC) at run-time to panelA's Controls collection.

So each time btnAdd is clicked, I do the following in its event handler: 1) add a new myUC() to panelA's Controls collection 2) call a helper method to set the Locations of all the myUC's on panelA (the only controls on ...Show All

  I have created tables within SQL Server database. My tables I have created do not have the dbo ownership( )...how does one transfer a table to dbo advTHANKSance It actually depends on which version of SQL Server you are using.
