Rainmeter query interface based on Window Message
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
1) Post the query to Rainmeter (E.g. QueryRainmeterSkinsPath function)
|
||
|
|
* target window : Rainmeter(TrayWindow)
|
||
|
|
* message : WM_QUERY_RAINMETER
|
||
|
|
* wParam : QUERY ID (RAINMETER_QUERY_ID_XXXXX)
|
||
|
|
* lParam : window handle which receives WM_COPYDATA
|
||
|
|
|
||
|
|
2) Retrieve the data received from Rainmeter, on WM_COPYDATA
|
||
|
|
* COPYDATASTRUCT->dwData : QUERY ID (RAINMETER_QUERY_ID_XXXXX)
|
||
|
|
* COPYDATASTRUCT->lpData : requested string in wide char
|
||
|
|
* COPYDATASTRUCT->cbData : size of lpData
