See this article[^] by Raymond Chen? Although not exactly the same situation, the advice is still applicable.

Yes, just use a SW hook (classic code, Win32)

Hi Gurus,
I have a simple application, which pops a message box if it is invoked in a pre-logon mode (i.e. when the system displays the login screen).
How do I get to know if the application is invoked before the user is logged on??
I tried using
GetProcessWindowStation() - but this doesn't help.
NOTE: The application will be invoked from a service.
Thanks in advance.

How about GetUserName() or NetWkstaGetInfo(102) or <code>NetWkstaUserEnum() ?

This is both syntactically wrong and just plain weird looking. How about:
COleException e;
if (! app.CreateDispatch("Excel.Application", &e))

Did you remember to call AfxOleInit()?

Hello
Oh sorry CreateDispatch was written twice
I wrote
if(!app.CreateDispatch("Excel.Application"))
{
AfxMessageBox("Couldn't start Excel and get an application 0bject");
return;
}
The above is not working

Why not? Are you looking at the exception object (specificaly it's getter method) like I suggested?

Hello
Yes still excel doesnt start

if(!app.CreateDispatch("Excel.Application",&e))
{
AfxMessageBox("Couldn't start Excel and get an application 0bject");
return;
}
i wrote the above

Did you somehow think that simply creating the object would make it all better?  What's the "value" of e?
What type of object is app?

it is like this
_Application app;
e is not initialised
|
|
|
|

Ok, and how did you go about creating the _Application class? In other words, how did you import it from Excel's type library? See the latter part of this article for one way.

I have include the type library through class wisard automation
and
#include "excel.h"
on top of the file
|
|
|
|
|
i need not write the import command since i have already included through
automation type library
isnt it
|
|

|

Correct. There are two ways of getting access to Excel's COM interface.
If you look at the COleException object when CreateDispatch() fails, does it hint that the COM library has not been initialized?

In the watch window the value of e doesnt change even after the function is called

It's created on the stack so why would it change? You have to call it's GetErrorMessage() method.

When i call the GetErrorMessage() the string is blank
LPTSTR f;
e.GetErrorMessage(f,0);
f is blank

Of course it is! You've not only given it an invalid buffer, you said the buffer's size is 0.

when i give 50 or 100 it gives me debug assertion failed

And rightly so since you've given it an invalid buffer. Did it ever occur to you to check here? As this is all elementary stuff, I'm thinking Excel Automation might just be a bit beyond your current skillset.

I knew this thread was about 15 posts too long. See here. Since you did not answer, I just assumed you had it right and the problem was elsewhere.
