SYMPTOMS
The error "Property Command Not Found" is displayed when you try to modify the caption of a command button in a command button group. The code used to access the command button is: FOR I = 1 TO 10 THISFORM.CommandGroup1.Command(I).Caption = "test"+ALLTRIM(STR(I)) ENDFOR



CAUSE
Visual FoxPro cannot interpret the reference made to Command(x). It is reading it literally, expecting an array member called command. The "Property Not Found" error message (error 1734) is displayed when a property cannot be located. It is sometimes the direct result of a typing error, and can be displayed if you are trying to access an object or a property.



RESOLUTION
In this specific case, you can use the Buttons collection to access every command button of a command group. For example, you can place the following code in the Init of the Command Group: FOR I=1 to THISFORM.CommandGroup1.ButtonCount THISFORM.CommandGroup1.Buttons(I).Caption="TEST"+ALLTRIM(STR(I)) ENDFOR You can also evaluate the expression that returns the command button name as follows: FOR I=1 to THISFORM.CommandGroup1.ButtonCount oRef=EVAL("THISFORM.CommandGroup1.Command"+ALLTRIM(STR(I))) oRef.Caption="TEST"+ALLTRIM(STR(I)) ENDFOR



STATUS
This behavior is by design.



MORE INFORMATION
To isolate the source of the problem when you receive a "Property Not Found" error message during program execution, you can suspend execution of the program. If the object has been created, you can use the AMEMBERS function or the DISPLAY OBJECT command to verify the name of properties and object members. For example: DISPLAY OBJECT LIKE Thisform
