Understanding TJumpList

[JackT 1]

When right clicking my programs toolbar button it open the JumpList menu. I can add a Task which runs a program when selected with command line parameters ?

Is there any way to simply send a command to the program generating the taskbar button so that it executes the command against the current instance ?

I just want to add a function to show a hidden window.

 

Thanks for any help in advance

My work around is to create a dll and call a function in it using RunDLL32 as the Task. I pass in the windows handle of my main window along with the name of the function I want to execute. The DLL posts a message to the main program window to make it do the thing I wanted it to do.

I used an EXE built in an older version (smaller size), it parses the cmdline, registers a mutual Windows Message then sends it back in the form of a WM_CopyData message.

 

Note:  WM_CopyData works across Application and Bitness boundaries

Or, you could just have the main EXE do that same work in its startup code to send the message to an existing instance of itself.  This has the added benefit that if there is no existing instance running, the new instance can continue to load itself normally, and then take the requested action when ready.
