Routine Description:
|
||
|
|
|
||
|
|
This function adds a printer connection on this machine
|
||
|
|
to the specified printer. This routine will return the real
|
||
|
|
printer name if the connection is established. Note a printer
|
||
|
|
connection can be added using the share name, thus this routine
|
||
|
|
will build the connection and then convert the share name to
|
||
|
|
the real printer name.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
hWnd - Parent window for any error UI.
|
||
|
|
pszPrinter - Printer name (e.g., "\\test\My HP LaserJet IIISi").
|
||
|
|
pstrPrinterName - Where to place the real printer name
|
||
|
|
This is used when a user connects using a share name
|
||
|
|
but the caller needs the real printer name to set
|
||
|
|
the default printer. This parameter can be NULL if the
|
||
|
|
real printer name is not needed.
|
||
|
|
pstrComment - Where to place the comment
|
||
|
|
pstrLocation - Where to place the location
|
||
|
|
pstrShareName - Where to place the share name
|
||
|
|
|

|
|
Return Value:
|

TRUE the printer connection was added. FALSE if an error occurred.

Routine Description:

This routine is the worker thread call back routine. It is called after the

progress UI has been started and is currently being displayed. Because this

function is a virtual within the TAsyncData class any specific data needed

by this routine must be fully contained within the derived class. This routine

accepts on argument a pointer to the progress dialog pointer. If needed this

|
pointer should be used to stop the progress UI if any UI must be displayed.
|

The hwnd of the progress UI should be used as the parent of any windows
