Credit card reader

[TimStone]

I'm testing a credit card reader. Right now I have a field on a dialog and when I swipe the card it will read the data into the field. However, I don't really wnat to show anything accept the message SWIPE CARD and then have the data read into a buffer.

I know I'm overlooking some way of doing this ... far too much on my mind. Any hints to get me on track ?

Hi Tim

Just a thought - I can't test it here. If you can read it into a "field" - I guess you mean a TGet, can you go:

Code: Select all  Expand view

oMyGet:Hide()

to hide the TGet so user won't see the data, but hopefully it will still accept it?

(I assume TGet:Hide() or an equivalent exists in FiveWin, it does in FiveLinux)

Another possibility would be to use the PASSWORD option on the TGet.

I hope I've understood the problem.

Good luck and happy programming

Hello Tim,

Simply put the GET at -100,-100 so it is out of sight of your dialog. I use it all the time to have a hidden default (ENTER) button on a dialog.

Patrick,

>hidden default (ENTER) button on a dialog.

I am curious why you would want this? Shouldn't the users be able to see the default button?

In some situations? No, we don't want to let the user see the default button

I'm not sure what you are saying. In some situation you don't want them to see it, or only in some situations you do want them to see it?

It is standard window behavior for there to be two buttons on modal dialogs, OK (the default) and Cancel.

What situations would you want to hide the default button and why?

In some situations I don't want to show the default button. For example if I have a dialog where I have a BITMAP that acts like the default button. So, I tell my users that that image is the default button.

Like this dialog for example:


The green button is just a BITMAP placed on the dialog, but it "acts" as the default button.

OK, that is a good solution.

After looking at the TBtnBmp and TButton classes, I see that the TBtnBmp class doesn't have a DEFAULT parameter. Thus, the reason you have to use to this trick. [I am assuming the green button is a bitmap button.]

Antonio, is it possible to add the DEFAULT parameter to TBtnBmp?
