注解Remarks

如果未不选择任何文本, SelText属性将包含一个值。If no text is selected, the SelText property contains a Null value.

若要设置或返回控件的这个属性,控件必须获得焦点。若要将焦点移到某个控件,使用SetFocus方法。To set or return this property for a control, the control must have the focus. To move the focus to a control, use the SetFocus method.

示例Example

下面的示例使用两个事件过程来搜索用户指定的文本。要搜索的文本在窗体 Load 事件过程中进行设置。“Find”按钮(用户单击后可进行搜索)的 Click 事件过程将提示用户输入要搜索的文本;如果搜索成功,则在文本框中选取该文本。The following example uses two event procedures to search for text specified by a user. The text to search is set in the form's Load event procedure. The Click event procedure for the Find button (which the user clicks 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 ' SetFocus to text box. 
 ctlTextToSearch.SelText = "This company places large orders " _ 
 &; "twice a year for garlic, oregano, chilies and cumin." 
End Sub 

Sub Find_Click() 
 Dim strSearch As String, intWhere As Integer 
 Dim ctlTextToSearch As Control 
 ' Get search string from user. 
 With Me!Textbox1 
 strSearch = InputBox("Enter text to find:") 
 ' Find string in text. 
 intWhere = InStr(.Value, strSearch) 
 If intWhere Then 
 ' If found. 
 .SetFocus 
 .SelStart = intWhere - 1 
 .SelLength = Len(strSearch) 
 Else 
 ' Notify user. 
 MsgBox "String not found." 
 End If 
 End With 
End Sub
