NAME: InvokeModemWizard
|
|
|
|
SYNOPSIS: Starts the modem install wizard
|
|
|
|
ENTRY: hwndToHide - this window, if non-NULL, will be hidden while
|
|
the modem CPL runs
|
|
|
|
EXIT: ERROR_SUCCESS if successful, or a standard error code
|
|
|
|
NOTES: launches RUNDLL32 as a process to run the modem wizard.
|
|
Blocks on the completion of that process before returning.
|
|
|
|
hwndToHide is not necessarily the calling window!
|
|
For instance, in a property sheet hwndToHide should not be the
|
|
dialog (hDlg), but GetParent(hDlg) so that we hide the property
|
|
sheet itself instead of just the current page.
