L_INT EXT_FUNCTION L_InetSendAttachBitmapCmd(hComputer, uCommandID, uBitmapID, uWindowID)
|
L_COMP hComputer; |
/* handle to a remote computer */ |
|
L_UINT uCommandID; |
/* command id */ |
|
L_UINT uBitmapID; |
/* bitmap id */ |
|
L_UINT uWindowID; |
/* window id */ |
Sends an attach bitmap command to a remote computer.
|
Parameter |
Description |
|
hComputer |
Handle of the remote computer to which the command will be sent. |
|
uCommandID |
Command ID. Each command sent by a member of a connection should have a unique ID. Since a member of a connection may send several commands, this ID allows that member to identify when a specific command request has been completed. |
|
uBitmapID |
The ID of the bitmap being attached. If the bitmap is successfully attached, then this bitmap will be painted whenever the window paints itself. |
|
uWindowID |
The id of the window that was just created. |
Returns
|
SUCCESS |
This function was successful. |
|
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The remote computer should respond by calling L_InetSendAttachBitmapRsp in its INETCOMMANDCALLBACK function. This callback function must be set using L_InetSetCommandCallback.
Once the remote computer receives this command it should always paint the specified bitmap inside the specified window. Both the bitmap and the window should exist on the remote computer. The remote computer will most likely paint the window at 1:1 ratio, adding scrollbars if possible. To change the way the bitmap is painted, call L_InetSendSetRectCmd.
The INETCOMMANDCALLBACK function will receive the uBitmapID and uWindowID information in the pParams parameter. The uBitmapID information will be in pParams[0] and the uWindowID information will be in pParams[1].
To receive responses to commands, provide an INETRESPONSECALLBACK function. This function must be set using L_InetSetResponseCallback.
