How to send 'F1' key as ASCII character?

Another related question, what if I'm trying to send the key F1, which is a combination of several characters, i.e. Chr(27) & "O" & "P"?

from what I know, the function keys don't have ASCII correspondants ...

if you want to "send" the key to the active window, then it would be:

SEND "{F1}"

then, as I feared, the answer is: you cannot do that directly.
the only option is to have a coded string (like the Send function does), which needs to be interpreted ...

In VB (such as VB 6), use
SendKeys "{F1}"
to send F1 to the program and control that currently has the focus.

angellll: Can you show me roughly what you mean?

Lethauser: I am using VBA. Sending 'F1' does not work.

LeithauserCommented:
Sorry. There really should be a box to check or something on these questions that tells us what language people are using.

Not your fault. I should have clarified this at the beginning.

Believe me, you are not the first. I have lost count of how many times I have given a VB 6 solution to a question and then been told by the person that it does not work because they are using VBA or VB.net, or something else. I think that Experts-exchange should have some kind of check box on all programming questions so that people can (have to, in fact) specify which Visual Basic language they are using.

Anyone has got any idea how to solve this problem? Thanks.

Guy Hengel [angelIII / a3]Billing EngineerCommented:
as I said: F1 key does not have an ASCII code.
so, you have to define some other ascii code combination to represent F1, aka the receiving side of the data stream has to look for this and say: this is F1 ...

for example:
sending "{F1}" is to be understood as "F1", while sending "{{}" shall be read on the receiving side as "{"

I found a way to get around this problem.data is obtained from the Excel sheet.

Function MySend(ByVal data As String)
'    DoEvents
    If LCase(data) = "chr(13)" Then data = Chr(13)
    
    If LCase(data) = "chr(27)" Then data = Chr(27)

    If LCase(data) = "chr(27)&o&p" Then
        wsTCP.SendData (Chr(27) & "O" & "P")
        Exit Function
    End If
    
    wsTCP.SendData data
    
End Function

Open in new window
