Msgbox issue?

[badkarma]

Weird one here,

I did a msgbox with a message, but forgot to put in a title (not even "") but with a button and icon selection ... for example ...

msgbox("hello world",cMsgboxYesNo,cQuestion)

... this resulted in a msgbox with just an OK button and a title message of "4"

To replicate as an example, the code is shown below, first a good msgbox, second a badly formatted msgbox function

Sub Globals
'Declare the global variables here.

End Sub

Sub App_Start

Msgbox ("This is the first yes/no test with title","Exit", cMsgBoxYesNo,cMsgBoxQuestion)
Msgbox ("This is the second yes/no test, but this time without title", cMsgboxYesNo,cMsgboxQuestion)

End Sub

But, both the compiler and the PDA when running the EXE , allow execution, albeit on the problematical msgbox, it shows "4" in the title and has OK instead of Yes / No as buttons. (I guess the "4" is the internal number for cMsgboxYesNo?)

Is this a bug in the checking of code at compile time which cannot detect my dumb programming / missing "" ?

You should add a comma like below, MsgBox needs 4 variables !

in you code
1. "hello world" is the text
2. cMsgboxYesNo is the title
3. cQuestion=0 is equivalent to cMsgBoxOK
4. missing

The constant for Question mark is cMsgBoxQuestion and not cQuestion !

msgbox("hello world",,cMsgboxYesNo,cMsgBoxQuestion)

Best regards

Yes, thank you Klaus, I understand this, but what I am saying is perhaps at runtime, BASIC4PPC should perhaps be a bit more intelligent and pick this issue up and show a compile error
