ASP.NET Membership Password Reset

Crystal — Mon, 17 Nov 2008 19:31:00 GMT

Someone wanted to reset their password for their aspnet membership site. Since I didnt have the source code only the database information, I had to create a new project with only a page setup for password changing. Make sure you set the new projects web.config file to match the role provider information for the database currently used.

</connectionStrings>

<add name="SqlProvider" type="System.Web.Security.SqlMembershipProvider"

connectionStringName="name" applicationName="name" enablePasswordRetrieval="false"

enablePasswordReset="true"

requiresQuestionAndAnswer="false"

requiresUniqueEmail="true"

minRequiredPasswordLength="4"

minRequiredNonalphanumericCharacters="0"

passwordFormat="Hashed"/>

</providers>

</membership>

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

If TextBox2.Text = TextBox3.Text Then

Dim strun As String = TextBox1.TextDim user As MembershipUser = Membership.GetUser(strun)

user.UnlockUser()

Dim oldpswd As String = user.ResetPassword()

Membership.GetUser(strun).ChangePassword(oldpswd, TextBox2.Text)

End If

End Sub

Adding lines to an HTML Table in code (VB.NET)

Here's a useful tip for adding lines to an html table in code. Normally I'd define and populate a grid, but sometimes that's overkill

 'declare the row
Dim tr As New HtmlTableRow


'declare the new cells
Dim td1 As New HtmlTableCell
Dim td2 As New HtmlTableCell


'set the content
td1.InnerHtml = "something"
td2.InnerHtml = "something else"


'set the ID property. This allows you to attach a CSS class to the cell
td1.ID = "report_cell"
td2.ID = "report_cell_title"


'another way to set a style
td1.Style.Add("width", "50px")


'add the cells to the row
tr.Cells.Add(td1)
tr.Cells.Add(td2)


'add the row to the table. This table is not declared in the code behind, it is a reference to a table in the 
'.aspx page declared like this:
'<table id="tblReport" runat="server"></table>
tblReport.Rows.Add(tr)

Disabling buttons on click in ASP.NET

Just to give props, I found this here: http://geekswithblogs.net/jwhitehorn/archive/2006/06/17/82214.aspx

but I don't like to leave valuable info on the internet, it might get deleted. Plus, I have to spend the 30 minutes hunting it down again <smiles>

We have all seen the websites that disable "submit" buttons when you click on them. This is often done to prevent users from clicking the button multiple times.
Normally this is accomplished using an 'onclick' JavaScript event to disable the button. In ASP.NET, each server side item already has a onclick event handler which calls the server back for event processing.
To accomplish the same thing in ASP.NET, you could easily do:

 Button1.Attributes.Add("onclick", "this.disabled=true;" + ClientScript.GetPostBackEventReference(Button1, "").ToString())
