Mapping Clipper Alert() to MsgYesNo()

[CCH4CLIPPER]

Hi

I use Alert() everywhere in FAS4HMG as my dialog of choice.
Do you think it is a good idea to create a say cch4clipper.ch file and map Alert() to MsgYesNo() ?

Hi CCH

AFAIK Alert() have multiple ( unlimited) options. MsgYesNo() don't accept any option and support automatically two ( "yes" and "no" ).

If all of your Alert()s have always "yes/no", you may map it. Still you have change your source code, because of parameters aren't identical.

Hi CCH,

Please be so kind to review the following direct replacement for Clipper ALERT() function:

Hi Grigory

I think I saw a link to walert() somewhere in the net this afternoon. Could be at extendedHMG site...
But when I clicked on the link, I get the 404 not found error

So, I couldn't believe it when you posted walert().
I will checked it out and report back here.

Hi

Is walert.prg compatible with HMG ?

Using compile.bat to compile walert.prg, I get :-

walert.prg(34) Error E0030 Syntax error: "syntax error at 'AITEMS'"

walert.prg(35) Error E0030 Syntax error: "syntax error at 'CMESSAGE'"

walert.prg(37) Error E0030 Syntax error: "syntax error at 'CTITLE'"

walert.prg(42) Error E0030 Syntax error: "syntax error at 'INTERACTIVECLOSE'"

walert.prg(124) Error E0030 Syntax error: "syntax error at 'WINDOW'"

walert.prg(125) Error E0030 Syntax error: "syntax error at 'INTERACTIVE'"

Where should I go from here ?

Had you added #include "minigui.ch" ?

Hi CCH

Please also take a look to MsgMulti at HMG Resources \ HMG Samples \ Misc Samples topic.

Hi CCH

Please add also #include "common.ch"

[CCH4CLIPPER]

Hi Grigory

Yup, no come error but testing out alert() does not give any response

Function ReindexAll()
nChoice:=Alert('Reindex All Files',{'Yes','No'})
Alert(Str(nChoice))

Return

DEFINE TOOLBAR ToolBar_1 BUTTONSIZE 32,24 BORDER
BUTTON Button_Reindex ;
CAPTION '&Reindex All' ;
PICTURE 'task-2.bmp' ;
ACTION ReindexAll()
END TOOLBAR

Clicking Reindex Btn does not give any response at all.
FYI, Using MsgInfo('Reindex') does work, so I think walert.prg has some issues.

Would appreciate any help here.
