Message Mapping?

[OSR]

I have a prgm that's only job is to send BM_CLICK messages; also, this prgm luanches a third-party app using the CreateProcess() function.&nbsp;&nbsp;What I need to know is that when the BM_CLICK message is generated it will go to my Message<br>Map and from there I would like to route the message to a button in the third-party app.&nbsp;&nbsp;Is this possible, the message map will screen for the CLICK message and then route directly into an ID_BUTTON of the third-party prgm.&nbsp;&nbsp;Usually, the Message Map takes two params the message being screened for and the function its routed to, Id like to replace the function param with the ID_ of the button.<br>&nbsp;<br>Can this be acheived?<br><br>thanks for any help
