reset command

how to write the code to clear the content inside text box when the button is press.

Code:

---

Private Sub Command1_Click()
Text1.Text = vbNullString
End Sub

---

Properly:

Code:

---

Private Sub Command1_Click()
  Text1.Text = ""
End Sub

---

Although Hack's code works, vbNullString is not the same as a zero-length string. That's directly from MSDN, which also states that vbNullString is used for calling external processes.

have a look at this, I thought it was kind of interesting

Code:

---

Private Sub form_Click()
 Dim S As String
 Debug.Print vbNewLine & "StrPtr with a VB string"
 S = " ":                  Debug.Print """ "" ="; StrPtr(S)
 S = "":                    Debug.Print """"" ="; StrPtr(S)
 S = vbNullChar:            Debug.Print "vbNullChar ="; StrPtr(S)
 S = vbNullString:          Debug.Print "vbNullString ="; StrPtr(S)
 
 Debug.Print vbNewLine & "Now StrPtr for a textbox"
 Text1.Text = " ":          Debug.Print """ "" ="; StrPtr(Text1.Text)
 Text1.Text = "":          Debug.Print """"" ="; StrPtr(Text1.Text)
 Text1.Text = vbNullChar:  Debug.Print "vbNullChar ="; StrPtr(Text1.Text)
 Text1.Text = vbNullString: Debug.Print "vbNullString ="; StrPtr(Text1.Text)
End Sub

With a VB string the only way to clear the BSTR is with vbNullstring, but the Text property also clears the BSTR with "" and vbnullchar. By clear I mean makes the string variable point to a null structure.
