Thanks a lot.

Does anybody know how to change the menu font size?

Thanks idle.
You are already very helpful.
May be I consider to better change to use structure list.

This is my version of string handling in IIF
Procedure.s IIFEvalss(expr,y.s,n.s)
If expr
ProcedureReturn y
Else
ProcedureReturn n
EndIf
EndProcedure
Macro IIFSS(expr,y,n)
IIFEvalss((Not(expr)),n,y)
EndMacro

Debug iifss(1=0,"TRUE","FALSE")
Debug iifss(1=1,"TRUE","FALSE")

Not allow to REDIM the 1st dimension?
What will be the alternative to increase the dimension size?

Thanks idle, very tricky!

Please help. I do not understand why I cannot REDIM my array

Dim GV.l(1,2)
GV(0,0) = 100
GV(0,1) = 200
GV(1,0) = 300
GV(1,1) = 400
ReDim GV(2,2) ; <------------------ ERROR
GV(2,0) = 1100
GV(2,1) = 1200
For Count = 0 To ArraySize(GV())
Debug Str(GV(Count,0))+","+Str(GV(Count,1))
Next

Error log ...

Thanks Bullfrog

When I pass the fifth parameter to the call back procedure, how can I retrieve it from ...

Thank for the help

From the manual, it is allowed to optionally set the fifth window call back parameter "#Window"
SetWindowCallback(@ProcedureName() [, #Window])

How can I retrieve this information from the Call back function?

Procedure WinCallback(hWnd, uMsg, wParam, lParam)
debug str(#Window ...

Thank you for your help

I refer to the manual about the pointer, my codes below cannot retrieve the text.
Please help

Example:
Text$ = "Hello"
*Text = @Text$ ; *Text store the address of the string in memory
*Pointer.String = @*Text ; *Pointer points on *Text
Debug *Pointer\s ; Display the string living at the ...

Thanks

I see a lot of procedure/function in PB is having optional parameter
For example, Result = ButtonGadget(#Gadget, x, y, Width, Height, Text$ [, Flags])
The "Flags" is optional parameter

How can I create such procedure/function in PB with optional parameter?
