  Getting error: Overload resolution failed because no accessible 'Substring' accepts this number o...

   Dear Forum
  
  I am trying to make it so users can select more than one checkbox and search a table for all the selected options.
  
  Any idea where I am going wrong on this?

  Thank you for your help. I totally appreciate it.

  Here is the error I am getting:        

  Compiler Error Message: BC30516: Overload resolution failed because no accessible 'Substring' accepts this number of arguments.
  Source Error:

  Line 77: Line 78: If chkboxes.length = 1 Then Line 79: inStatement= inStatement.Substring Line 80: end if Line 81: Instatement = instatement &')'

  Here is my main code:

  Dim chkboxes (5) As Integer

  If bedroom1.checked = true
  chkboxes (0)=1
  end if

  If bedroom2.checked=true
  chkboxes (1)=2
  end if

  Dim inStatement As String
  inStatement = "("

  For i As Integer = 1 To 100

  If chkboxes(i)<>0 Then

  'If chkboxes (i) Is Not Nothing Then
  inStatement = inStatement & chkboxes (i)
  end if
  Next

  If chkboxes.length = 1  Then
  inStatement= inStatement.Substring
  end if
  instatement = instatement &')'
  Next;

  Substring (0. instatement length -1)

      
    
   The part of the code that queries the database:
   
  dim SqlCmd as new StringBuilder() SqlCmd.Append("SELECT * FROM plans WHERE Planname LIKE  '" & Plannametext & "' AND  Sqrft >= '" & Sqrftminint & "' AND  Sqrft <= '" & Sqrftmaxint & "' AND Wide <= '" & Wideint & "' AND Deep <= '" & Deepint & "' AND Bedrooms in ('2','4')'  AND  Floors = '" & Floorsint & "' AND  Garages >= '" & Garagesminint & "' AND  Garages <= '" & Garagesmaxint & "'  AND  Alleyfront = '" & Alleyfrontint & "' AND  Baths >= '" & Bathstext & "' ")

  String.SubString() expects at least one parameter: http://msdn.microsoft.com/en-us/library/system.string.substring(v=vs.110).aspx

  Hi jeffwood,

  The issue that you didn't set a parameter to the Substring method.

  You need to use it like below:

  string a="xxxxxxx";
  string s=a.SubString(2);

  Here is a working demo for you:

  Best Regards,

  Please Mark as Answer If it help you,thanks

  Thanks for your help.

  Here is the adjusted code that we came up with that makes it work:

  Dim chkboxes (5) As Integer

  If bedroom1.checked = true chkboxes (0)=1 end if

  If bedroom2.checked=true chkboxes (1)=2 end if

  If bedroom3.checked = true chkboxes (2)=3 end if

  If bedroom4.checked=true chkboxes (3)=4 end if

  If bedroom5.checked=true chkboxes (4)=5 end if

  Dim inStatement As String inStatement = "("

  For i as integer =0 to chkboxes.length -1

  If chkboxes(i)<>0 Then

  inStatement = inStatement & chkboxes (i) & "," end if Next

  If chkboxes.length = 1 Then inStatement= inStatement.Substring(0) end if

  inStatement = inStatement.Substring (0, instatement.Length -1)

  inStatement = inStatement & ")"
