I tried If "Adm_A" Like "Adm_?" Then and it works.
Try debugging and see what the actual contents of txtUserName.Text is.

What's the Length of txtUserName?
if the Text in txtUserName is "Adm_A" then If condition Works
If the Text in txtUserName is "Adm_As" then If condition will not work...

The '?' indicates that you except one character, if you want to except zero or more use '*' instead.

Try this, I hope this will help you...

As long as I Check this IF condition is Length and Case Sensitive,
* "?" accepts only 1 Character when Matching
* "Adm" is not Equal as "ADM" or "adm".

By Subjecting these limitation my solution is here...

VB

If Ucase(Mid(txtUserName.Text, 1, 5)) Like "ADM_?" Then
    Response.Redirect("Address1")
Else 
    Response.Redirect("Address2")
End IF

Accept Solution if it works...

Solution 5

As we know in VB.Net, LIKE operator with ? sign only takes single character(Any single character). And you are giving more than one extra character in that.

Refer the link below for more explanation in like operator.

Solution 7

Try(if case-sensitivity is not a concern for your condition):

VB

If txtUserName.Text.Trim().ToLower() Like "adm_?" Then
            Response.Redirect("AdminLoggedIn.aspx")
        Else
            Response.Redirect("LoggedIn.aspx")
        End If
