Need Help with INSERT INTO

Apr 26, 2010 10:24 PM|LINK

I have encountered an error that I don't quite understand. I am setting up a website for some friends of mine and I'm trying to setup an admin page that will allow future users to be assigned permissions after the site is deployed. I hit a few errors during the creation that had to do with my general lack of coding skills, but the error I'm getting now I don't think I caused. Here is the error that I'm getting:

Server Error in '/NstazMainSite/Nstaz' Application.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

        Dim Mycmd As Data.SqlClient.SqlCommand
        Dim NewRole As String = ddlRole.SelectedValue
        Dim sUser As String = ddlUser.SelectedValue

        Mycon = New Data.SqlClient.SqlConnection("Server=VHS03.Jonny11b.com; Database=nstaz_AppData; User ID=*******;Password=*******;")
        Mycmd = New Data.SqlClient.SqlCommand(appUsersRolesDS.InsertCommand, Mycon)

        Mycon.Open()
        Mycmd.ExecuteNonQuery()
        Mycon.Close()

    End Sub

End Class

The database that I'm working with was generated by the asp.net tool Aspnet_regsql.exe and the pre-packaged asp.net web site tool. Please help, I don't understand why the table won't allow me to just take the UserId and RoleId and place them in to the correct table. What am I doing wrong?

If I'm answering questions something in the Universe is broken. :)

Are the values of the two DDLs, GUID values? If so you need to convert the string to GUIDs, so something like this:

Guid NewRole = new Guid(ddlRole.SelectedValue);
Guid sUser = new Guid(ddlUser.SelectedValue);

(Not a VB person, so use my signature below to translate to VB).

Edit: Corrected code to be Guid instead of string.

I guess I should have clairified. Yes the ddl are databound to the database with the value fields bound to the *Id colums from the sql tables. The *Id colums in the database are set to the data type UniqueIdentifier. I was trying to just take the user id from the table users and the role id from the roles table and add them to the UsersInRoles table in the .net database. I'm going to give your suggestion a try next break I get at work and let you know how it goes.

So I attempted to use the command that you posted after converting it to the VB language. Here's a screen shot of what VB studio had to say about it:

Don't know how to proceed.

Dim NewRole as Guid = blah blah

Edit: it was a mistake in my posted code. I corrected the ealier post to use Guid instead of string. Sorry.

No worries about the typo, believe me I'm grateful for the help. I have made the update to the code as noted in you post, I also removed the comented lines to avoid any possible issues. Here is how the page reads:

Partial Class Admin_UserSettings
    Inherits System.Web.UI.Page


    Protected Sub btnAssign_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAssign.Click




        Dim Mycon As Data.SqlClient.SqlConnection
        Dim Mycmd As Data.SqlClient.SqlCommand
        Dim NewRole As Guid = New Guid(ddlRole.SelectedValue)
        Dim sUser As Guid = New Guid(ddlUser.SelectedValue)






        Mycon = New Data.SqlClient.SqlConnection("Server=*******; Database=nstaz_AppData; User ID=*******;Password=*******;")
        Mycmd = New Data.SqlClient.SqlCommand(appUsersRolesDS.InsertCommand, Mycon)




        Mycon.Open()
        Mycmd.ExecuteNonQuery()
        Mycon.Close()


    End Sub








End Class

The error is the same:

I don't understand this malfunction, shouldn't the GUID just transfer over? What ever information you want that'll make it easier on you, I'll provide. I wish I could be of more help :(

In your original code I noticed two problems

UpdateCommand ="UPDATE aspnet_UsersInRoles SET RoleId = @NewRole WHERE (UserId = '@sUser')"
