Combo Box Control, Text Box Control.
You can use these properties for tasks such as positioning the insertion point, establishing an insertion range, selecting parts of strings in a control, and deleting text.
You can set the SelLength and SelStart properties using only a macro or Visual Basic. The SelText property is read-only.
To set or return these properties for a control, the control must have the focus (to move the focus to a control, you can use the SetFocus method).
Setting the SelLength property to a number less than 0 produces a run-time error.
Setting the SelStart property to a number greater than the number of characters in the control sets the property to the existing text length.
Changing the SelStart property cancels the selection, places an insertion point in the text, and sets the SelLength property to 0.
SetFocus Method, Text Property.
The following example uses two event procedures to search for text specified by a user. The text to search through is set in the forms Load event procedure. The Click event procedure for the Find button (which the user chooses to start the search) prompts the user for the text to search for and selects the text in the text box if the search is successful.
Sub Form_Load() Dim ctlTextToSearch As Control Set ctlTextToSearch = Forms![Form1]![TextBox1] ctlTextToSearch.SetFocus ' Move focus to text box. ctlTextToSearch.Text = _ "This company places large orders twice a year for" ctlTextToSearch.Text = ctlTextToSearch.Text _ & " garlic, oregano, chilies and cumin."Sub Find_Click() Dim strSearch As String, intWhere As Integer Dim ctlTextToSearch As Control ' Get search string from user.
