Shell Complete Flag?
Phil Field
the shelled program loads. I am opening the IE browser to a specific web site
and want to use SendKeys to populate the default text boxes on that site.
Currently, I use a loop to delay my vb code from going on until the web site is
loaded before using the SendKeys.
There must be some way of finding out when the browser has completed loading
AND the specific web page has finished loading. Does anyone have an idea?
Thanks,
Phil

========================
See this link
http://support.microsoft.com/support/kb/articles/Q129/7/96.asp
Note: This method doesn't use Shell -- it uses CreateProcessA
FAST AND DIRTY METHOD (WORKS ALMOST ALL THE TIME)
=================================================
Paste these lines in the (General)(Declarations) section of the form where the Shell is
being called (or remove the Private keywords and put them in a BAS module if more than one
form will use them):
Private Declare Function OpenProcess _
Lib "kernel32" _
(ByVal dwDesiredAccess As Long, _
ByVal bInheritHandle As Long, _
ByVal dwProcessId As Long) As Long
Private Declare Function CloseHandle _
Lib "kernel32" _
(ByVal hObject As Long) As Long
Private Declare Function WaitForSingleObject _
Lib "kernel32" _
(ByVal hHandle As Long, _
ByVal dwMilliseconds As Long) As Long
Call your Shell command in this form with the appropriate Shell arguments placed in the
parentheses:
PID = Shell( <<Put Shell Arguments Here>> )
And finally, paste the following IMMEDIATELY after the PID=Shell statement above (making
sure to handle the possible error where indicated; i.e. stop the code from falling through
to your other commands if the Shell failed):
If PID = 0 Then
'
'Handle Error, Shell Didn't Work
'
Else
hProcess = OpenProcess(&H100000, True, PID)
WaitForSingleObject hProcess, -1
CloseHandle hProcess
End If
One note -- there are some NT systems (those with VERY tight security measures in place)
where this call won't work. No problem at all on 95/98 though.

when the application has FINISHED. I need to know when the application has
completed LOADING so I can use SendKeys to populate textboxes on the web site.
Is this unrealistic? Is there a way to know that the application (in this
case the IE brower) has completed loading and is ready to accept keystrokes?
Thanks for your help and patience.

app, but worth a try. The second param in WaitForInputIdle is the
milliseconds to wait. You can specify a large number, such as 10000 to wait
10 seconds for the app to respond, or set it to INFINITE, which will suspend
your app until the process has started. If it never starts, using this flag,
you app will hang requiring a three-finger salute.
