Multi Function Control Buttons

[nonplus]

Can a command button be used in conjunction with an else/if statement i.e.
If command1_click()Then
Call New_Function Else
End
Replies would be much appreciated.
Cheers
Ross.

What???

Private Sub Command1_Click()
Call(MyFunct)
End Sub 'using only end, ends the program!

Private Function MyFunct()
Msgbox "????"
End Sub

hmm.. don't know what you're after!
You mean with a control array?

Private Sub Command1_Click(Index As Integer)
if Index = 1 Then Call(Funct1)
End Sub

??? please clarify

Pretty much, unless you have a seperate function that checks the state of the command button, if you have code in the Command1_Click() event, any time the button clicks, you have a solid confirmation that the button has been clicked (I hope that made sense ).

If you need a function that checks if a button has been clicked, take a look at what Job has. His first snippet is what I just talked about.

His second snippet is a bit more advanced, allowing you to make the code available for any number of command buttons, keeping the code in one place.

You could put some code in a timer that checks periodically the state of the command button. You'd need to use something that would allow you to record the state of the command button though. Consider this:

Dim Command1MD As Boolean

Private Sub Command1_Click()
    Command1.Tag = "Clicked"
End Sub

Private Sub Command1_MouseDown(Button As Integer, Shift As _
            Integer, X As Single, Y As Single)
    Command1MD = True
End Sub

Private Sub Command1_MouseUp(Button As Integer, Shift As _
            Integer, X As Single, Y As Single)
    Command1MD = False
End Sub

Private Sub Form_Load()
    Timer1.Interval = 10
End Sub

Private Sub Timer1_Timer()
    If Command1.Tag <> "" And Command1MD <> True Then
        If Command1.Tag = "Clicked" Then MsgBox _
           Command1.Caption & " has been clicked."
        Command1.Tag = ""
    End If
End Sub

Basically, I set the command button's tag to "Clicked" and in the MouseDown event I set a boolean to true. The nifty thing about this? Only if you click the button (click and release the mouse button) while you're on the command button does it generate the two conditions necessary for the timer to determine if you've actually clicked the button. So if you click the button and move off the button before you release the mouse button, it won't generate the result ...

You could conceivably create a different boolean called Command1Clicked and check against that (or Command1_Clicked for that matter) if it gives you more of a warm fuzzy.

What I am trying to do is use 1 command button for a variety of functions. e.g. when the program is run you are presented with a menu. You have to select a fuction of the program, this click event will take you to your desired program function. I then have a sub menu that needs to have 1 control button that can be used throughout the program for different purposes i.e. to enter information, to select further sub menu components from the list box etc.

If you don't have a clue what I am talking about I am trying to code a Flight Managment Computer. You can get info on them on the net that will probabaly better describe what I am trying to do.

Well one solution would be to use a public variable: declare a public variable like WhichFunction.

When you select for a specific function for your sub menu button, you set this value accordingly, i.e.

WhichFunction = 1 if you want the button click to enter information

= 2 if you want the button click to select further components, etc. etc.

The on Command1_Click event write something like:

Private Sub Command1_Click()
If WhichFunction = 1 Then
     EnterInformation
If WhichFunction = 2 Then
     SelectComponents
'etc.
End Sub

...which are all defined in a module.

Best regards,

Ah, okie (probably a little late on this)...

Well. I thought you wanted to see if the command button had been clicked ...

I also suggest the whichfunction variable method described above, if and only if, you have one button and only one button. If you need a sub-menu of several buttons, that change depending on which menu you're in (as in the number of them) use a control array for the command button. Then you can load/unload each individual button as needed.

Another way to parse through the command button 'functions' and I believe a better answer than if/then statements (unless you need to test for completely different things for each choice) is use the Select/End Select control structure. It's a bit faster and a bit more effecient.

Select Case WhatFunction
    Case 1
        ....
    Case 2
        ....
    Case 3
        ....
End Select

Hope this gives you some ideas you hadn't thought of yet.

Instead of making any new variables you can use the .tag property of the button to store what function was last done or is doing.
