[RESOLVED] on KeyPress error

[BubbleLife]

Hi all,

Just a quick problem -
I have a program that has a text box take focus when the program loads. I want it to display some text, which dissapears if you click / get focus in the box. Kinda like a lable. I also DON'T want it to make the label text dissapear when the program loads. I accheived this with the following code:

' Global declare thingy
Dim AA as Boolean

' More code

Private Sub MD51in_GotFocus()
If AA = False Then
    AA = True
    Exit Sub
End If

If MD51in.Text = "Actual MD5 Checksum" Then
    MD51in.Text = ""
    MD51in.SetFocus
End If
End Sub

Private Sub MD51in_LostFocus()
If MD51in.Text = "" Then
    MD51in.Text = "Actual MD5 Checksum"
End If
End Sub

Private Sub MD52in_GotFocus()
If MD52in.Text = "Supposed MD5 Checksum" Then
    MD52in.Text = ""
    MD52in.SetFocus
End If
End Sub

Private Sub MD52in_LostFocus()
If MD52in.Text = "" Then
    MD52in.Text = "Supposed MD5 Checksum"
End If
End Sub

However, I have noticed that if you start typing in that box right away, the "lable text" will remain. I tried countering this using an _change()..

Private Sub MD51in_Change()
If MD51in.Text = "Actual MD5 Checksum" Then
    MD51in.Text = ""
    MD51in.SetFocus
End If
End Sub

But it didn't work. The best solution I can think of is to use _KeyPress or _KeyDown:

Private Sub MD51in_KeyPress()
If MD51in.Text = "Actual MD5 Checksum" Then
    MD51in.Text = ""
    MD51in.SetFocus
End If
End Sub

But if I try that, it gives the following error:



Any ideas?

You need this in your function:

Private Sub MD51in_KeyPress([B]KeyAscii As Integer[/B])

Perfect! Thanks ^__^

Just another quick Q - Is there a maximum character limit that all MD5 checksums are, or are they all different?

[gavio]

I think 65k... but not sure

[BubbleLife]

65k? Kilobytes? I mean the actual key. thing. For example, the Checksum for Notepad.exe is
388b8fbc36a8558587afc90fb23a3b99

And this is the hash of a very large file, over 3 gigs:
897685ed1eef183514a3dafcb75115e9

They are all 32 characters - that wouldn't be the limit, would it? Or does it depends on the amounts of files or types of files?

"The 128-bit (16-byte) MD5 hashes (also termed message digests) are typically represented as a sequence of 32 hexadecimal digits."

Ah, so they are always expressed in 32 characters? I'll put that as the max length then XD.

Thanks!
