Easy trick to allow only text and converts it to upper-case. (Backspace is optional)
VBcodersPrivate Sub Text1_KeyPress(KeyAscii As Integer)
Select Case KeyAscii
Case 8
'Delete this line and backspace will not be allowed
Case 65 To 90
'UPPER-CASE is allowed, do nothing here
Case 97 To 122
'This is lower case. By turning off Bit-5 lower-case will converted to UPPER-CASE
KeyAscii = KeyAscii Xor 32
Case Else
'Other keys are not allowed. Set KeyAscii to 0 and nothing will be printed.
KeyAscii = 0
End Select
End Sub
