soft keyboard for touch panel operation

[stoeckel]

Hi,

I am writing an application with two layers on the panel: one for everybody and one for experts. The latter layer will be password-protected. The application shall only be operated via touchpanel. There will be no hardware keyboard. I have seen software solutions which were written in Visual Basic. They used a kind of soft keyboard which was shown on the screen if the user needed to type in a password. Does anybody know about a similar solution for LabVIEW?

Thanks for any hint,

Peter

Here are a few examples with keypads:

You can also use the System Exec VI to call the OSK executable. It will launch the windows virtual keyboard (OSK stands for On-Screen Keyboard). You will need to set the focus for your field after opening it.

hi there

under windows thats a feature of the os. i only know german windows (Start->Programme->Zubehör->Eingabehilfen->Bildschirmtastatur). search for %SystemRoot%\system32\osk.exe.

best regards

Hi folks,

great! I didn't expect the solution to be that simple.

There is one minor problem left: The user shall not be able to operate the windows key on the OSK because he would be able to leave the user interface of the running program. Is there any possibility to hide or to inactivate certain keys on the OSK?

Not that I'm aware of.

You can try 2 directions - build your own keyboard, similar to the examples I linked to or look into disabling the windows key in windows itself. I assume it will affect the virtual keyboard as well.
