Win8: Credential provider. CPUS_ONLOCK_WORKSTATION scenario

15-Sep-13 5:27

I have not managed to find a decent explanation for either of the error codes you received. All I can suggest is that you test with a Unicode and ASCII version of the string, and be sure that the path to the file is correct.

Hello,
I'm trying to solve one problem with custom cred.prov. on win8.
The problem is that if you select any tile (e.g. my, custom) and you have CPUS_UNLOCK_WORKSTATION scenario - Logonui will dismiss it automatically after 1 minute. This is not relevant to CPUS_LOGON scenario. Selected tile will stay untill user press Ok or Cancel buttons.

So I'd like to ask, maybe somebody has worked with such thing already, is it possible to handle that moment when selected tile is going to be dismissed.

using debugging I found that IConnectableCredentialProviderCredential::SetDeselected() is not called when IConnectableCredentialProviderCredential::SetSelected() is called by selecting the tile.

Re: ATL and MFC string conversion macros conversion macros

Hi,

using the OpenText method I have noticed the filename string has nulls in between by the time Automation is about to execute the request

I have looked at the documentation and I am not sure what macros to use to get this right

Can anyone help

Seems like the above error has to do with access rights

I am running windows 7
I right click on the file and under the security I see everything checked off but the special permissions don't know if that would be the problem

Without information on the context in which you receive the error it is impossible to speculate.

in excel, how to get the char after the cursor when in edit mode

13-Aug-13 20:28

That just means it is a Unicode string. I have explained to you a number of times about your mishandling of Unicode and ASCII strings, and I suspect this is just another example.

You really need to show the exceptions, rather than hoping people can guess what they are.

Hi,

I followed Microsoft Knoweldge base Article 178749

http://support.microsoft.com/kb/178749[^]

To create and an Automation When I got the Class wizard I selected Create Class from typelib

I the selcted the excel.exe

The Wizard create a number of Class I slected to include all of them in my project

After getting a Clean build I decided to add some ole code

create excel

So I included "CAppliction.h"

I coded CApplication app;
app.CreateDispatch("EXCEL APPLICATION");

however I got a whole slew of build errors

example
c:\users\4rypb\documents\visual studio 2010\projects\autoproject\autoproject\debug\excel.tlh(1595): error C2371: 'FontPtr' : redefinition; different basic types
1> c:\program files\microsoft visual studio 10.0\vc\include\comdef.h(314) : see declaration of 'FontPtr'

or
c:\users\4rypb\documents\visual studio 2010\projects\autoproject\autoproject\capplication.h(3): warning C4278: 'RGB': identifier in type library 'C:\\Program Files\\Microsoft Office\\Office14\\EXCEL.EXE' is already a macro; use the 'rename' qualifier

Am I mssing some include ?

The doc says include excel8.h

but I dont see that included generated

Thanks

there's going to be different headers eg excel8.h, for different versions of Excel - you've already said you're using Excel 2010, so, an alarm bell goes off in my head straight away on that score ...

as to the rest, its been a long time since Ive needed to do this, but I found this article here in CP that may give you some more (and definately) better guidance ..

Automating Excel 2007 and creating charts using C++ MFC application in Visual Studio 2008[^]

(before you shoot me down in flames, please have a look at the article - it suggests it should be good for Excel 2010 as well, else I wouldnt have posted it)

You need to trace to the point of the error and show the code that crashes and the reason.
