C# to VB.Net Conversion Error
Question
I have this piece of code where I'm trying to convert the below C# code to Vb.Net and place it in my content place holder and it gives me error as
Statement cannot appear outside of a method body/multiline lambda.
Can any one provide me the correct syntax.
Here is the C# script:
<script runat="server">
[WebMethod()]
public static bool CheckUserName(string userName)
{
return (Membership.GetUser(userName) != null);
}
</script>
I'm using tangible converter and it's conversion to VB.Net is here:
<script runat="server"> (WebMethod()) public static Boolean CheckUserName(String userName)
Return (Membership.GetUser(userName) IsNot Nothing)
</script>
And the entire code is here:
<%@ Page Language="C#"%>
<%@ Import Namespace="System.Web.Services" %>
<%@ Import Namespace="System.Web.Security" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

}
</script>

_divStatus = $get('<%= CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("divStatus").ClientID %>');
$addHandler(_txtUserName, "keyup", onKeyUp);
}
function pageUnload()
{
$removeHandler(_txtUserName, "keyup", onKeyUp);
clearTimer();
}
function onKeyUp(e)
{
setupTimer();
}
function setupTimer()
{
clearTimer();
_timerHandle = window.setTimeout(checkUserName, 500)
}
function clearTimer()
{
if (_timerHandle != null)
{
window.clearTimeout(_timerHandle);
_timerHandle = null;
}
}
function checkUserName()
{
if (_txtUserName.value.length > 2)
{
_divStatus.innerHTML = 'Checking...';
_divStatus.style.color = 'black';
PageMethods.CheckUserName(_txtUserName.value, OnCheckUserNameComplete, OnCheckUserNameError, _txtUserName.value);
}
}
function OnCheckUserNameComplete(result, userContext)
{
if (result == true)
{
_divStatus.innerHTML = String.format('\'{0}\' is already taken', userContext);
_divStatus.style.color = 'red';
}
else

Wow, this converter that you are using seems to kinda suck. I mean this public static Boolean CheckUserName that it spitted to you doesn't look much like VB.NET code to me.
Try this:
<script type="text/VB" runat="server">
<WebMethod> _
Public Shared Function CheckUserName(userName As String) As Boolean
Return (Membership.GetUser(userName) IsNot Nothing)
End Function
</script>
Also don't forget to change the language in your Page directive on the top of your webform.
And don't rely on automatic converters. Rely on your knowledge and skills when dealing with code.
