Calculator revisited

Calculator revisited

Postby TimStone » Thu May 22, 2014 10:24 pm

A client recently updated from a DOS version of my software to the Windows version. ( waited 15 years to do so ).

He is obsessed with the fact that he had a calculator in GET fields in the DOS version ( some people just can't let go ). I don't have it in those fields under Windows because a lot of the fields trigger lookups or automatic processes.

However, I'm thinking maybe it would help to have one. Mine are old so they would need to be revised to look clean in Windows.

Does anyone have an implementation of a calculator for GET fields ? It might be a nice addition to the GET control ...

Thanks.

Tim,

You can implement it quite easily using:

... GET ... ACTION WinExec( "calculator" )

If it is fine for you, then I help you to recover the value shown.

Of course it is even better to use a FWH calculator. Please try MsgCalc() from FWH
regards, saludos

Or Timm's class which seems to work very fine:

viewtopic.php?p=159435#p159435

the solution that you prefer :-)

Hi Antonio,

Right now I'm using an inline GET calculator. I would love to see how to recover the value from the WIndows Calculator since it's traditional. I'm also going to play with MsgCalc( ) which might work out.

Thanks.

Tim,

The problem with the Windows calculator is that unless the user press the "copy" menu option in the calculator, its value will not be saved.

If clicked, then we can retrieve its value from the clipboard. Its easy :-)

OK ... I took MsgCalc and re-did the layout a bit to be more conforming to my program ... so it's consistent with the existing fonts / brush etc. I will work OK ...

One quick question. I have a bitmap within a get ... no problem. However, would it be possible to put 2 bitmaps in there with 2 different action statements ?

Thanks

Gee, give him the moon and he wants the stars.

Maybe you could just put a button next to the Get for the second action.

James,

We need to do lunch !

Oh ... I have the button next to the get already. It works fine, but I have a crotchety old client who likes to point out its "different"

We do. Let me know when you are going to be in Carlsbad next time.

My philosophy is to ignore them and they eventually give up. Or, offer to work on it for an (inflated) hourly fee--that usually changes their mind on how important it is. In this case you could just tell them that this is not a Windows standard design and thus you can't support it anymore.

This is a rather funny situation. The guy has been running the DOS system forever, and kept "not updating" to the Windows version until the XP issue arose. However, he paid all those (15) years for the updates ... so he has "sort of paid" for some special attention.

I'm in Carlsbad often.
