How to send a message to the created palette

[satoshi shimokura]

hello. I am developing using API Development Kit 25.3002 (Windows).

I would like to send a DG_MSG_CHANGE message to the radio buttons in the palette I created.

The DGSendMessage function was described in the manual, so I tried to use it I'm having trouble finding an implementation.

I found the DGSendUserMessage function instead, but I don't know how to give the third argument DG::EventArg& msgData.

Is it correct to use DGSendUserMessage to send a message to the palette in the first place?

In addition, I tried to get the window handle with ACAPI_GetMainWindow or DGGetDialogWindow and execute the WindowsAPI SendMessage function.

It was no good.

Is there a way to send a message to the created palette?

Thank you very much.
