ToolBar Button State

[My NI]

Hello,

i am working on the TestStand 4.0 User Interface with C#.

Now i have built a ToolBar under the MainMenu. I can invoke the Commands by clicking ToolBar Buttons, and get the actual state (enable/disable) of most buttons, except Cut/Copy/Paste.

I don't think that the TestStand API or UI provides any method to indicate the custom UI Controls state. My last hope is to catch all WM_LBUTTONDOWN and WM_RBUTTONDOWN messages in the Sequence- and Variable-View. If something editbar is selected, set the Cut/Copy/Paste state to enable.

Have somebody better idea? Thanks!

I'm not 100% sure I understand your problem, but here are somethings to consider.

- the Enabled property of a Cut/Copy/Paste/Delete Command varies dynamically according to the current selection and focus. Make sure your toolbar or toolbar buttons do not steal the focus.  

- Are you using TestStand buttons? In 4.0, you can set the button image and you can set Button.Style to ButtonStyle_ToolBar. If this works for you, it could save some work.

- If you aren't using TestStand buttons, then you need to decide when to dim or enable the buttons. Some options are:

    a) Use a timer to periodically update them. It is okay if there is a slight lag because even if the button is still enabled when it shouldn't be, the command will be correctly enabled/disabled when the button invokes it..

    b) For each native button, connected the same command to a TestStand button that you hide. Handle the ConnectionActivity event for the TestStand button and update the corresponding native button in the handler.

Hi, James Grey,

thank you for your reply. English is not my mother tongue language

I have used the ToolStrip in Visual Studio 2005.

I have tried setting a timer with interval of 2000 ms, it worked, but i don't think it is a efficient way. You know, the TS 4.0 is using much memory.

I will try your suggestion (b), it is really a clever solution.
