How to use Windows Virtual-Key Codes with Special Characters such as $

[Lucianogob]

Hello,

I'm developing a Keyboard for a Touch Screen Windows 7 application and I need to have access to Special Characters such as $ % ^ and others but I can't find a way to use them from the Windows Virtual Keyboard. I'm using the following example which has all regular characters you can find on a keyboard.

Also I'm using information from the following MSDN documentation:

https://msdn.microsoft.com/en-us/library/windows/desktop/dd375731%28v=vs.85%29.aspx

The problem is that the Windows On-Screen Keyboard is able to type these special characters but I can't find their VK codes to use within LV.

Does anyone have any idea on how to do it?

Thanks and regards.

Hello Luciano,

I read the MSDN documentation and I understand that VK Codes reffer to keybord keys and not to keyboard characters, so if you need use a character that require combine more than one key you need code the combination that provide the disired character.

We also have a KB about it.

Hey Luciano,

Why don't you try calling the on-board screen, which is native to Windows.

I made a simple VI that you can use as a base code for your application. Give it a Try!

Best Regards.
