DotNetFactory interface functions (3) – Create TextBox

Parent page: Service Functions – DotNetFactory (QTP, VBScript)

Creating .NET objects from VBScript/QTP

You can create a TextBox (single-line Text Input object) and assign required properties within one line by calling the function below. The function has only optional parameters provided in the Dictionary object.

Currently supported optional parameters:

TextBox Width and Height.

TextBox Coordinates – Left, Top.

  • p.text – Text displayed by default
  • p.length – Max number of input characters
  • p.masked – If input needs to be secured (e.g. password textbox).
  • p.readonly – If editing is not allowed.

Note. You may code as many optional parameters as required. Just follow the established syntax and keep in mind that parameter index for Dictionary must be unique – otherwise it will overwrite the previous parameter.

  If intLength = 0 Then
   intLength = 100

  intLeft = IntVal(objParameter.Item("p.left"))
  intTop = IntVal(objParameter.Item(""))
  intMaxLength = InitLong(objParameter.Item("p.length"), 255)
  boolMasked = InitBool(objParameter.Item("p.masked"), FALSE)
  boolReadOnly = InitBool(objParameter.Item("p.readonly"), FALSE)

  Set objTextBox = DotNetFactory.CreateInstance("System.Windows.Forms.TextBox", "System.Windows.Forms")

  If boolMasked Then
   objTextBox.UseSystemPasswordChar = TRUE
  End If

  Set CreateTextBox = objTextBox
 End Function


Set objInputUserID = CreateTextBox(AssociateParameters("p.left = 25, = 100"))
Set objInputPassword = CreateTextBox(AssociateParameters("p.left = 25, = 150, p.masked = Yes"))
