• vej Unable to call "CoInitializeSecurity"

  Hi Everyone. I'm in trouble about DCOM server & client system in Vista.

• RaphaelGray Standard User Analyzer causes COM and ActiveX to fail

  We have a legacy application programmed in C++ and MFC that runs on Windows 2000 and XP but has problems with COM and ActiveX when run on VISTA. This app is built with Visual Studio 2003. I remotely debugged this app running on Vista from my development machine and found that the COM and ActiveX problems is the app trying to instantiate the COM components but they return E_ACCESSDENIED. I have checked the following: 1. The COM components on both my development machine (XP) and the test machine (VISTA) have the same ACL’s. 2. The access denied problem occurs if I am logged into the test machine (VISTA) as a local user or an administrator (Admin Approval Mode). 3. I added: HRESULT hr ...Show All

• qzrlsd Windows SDK installer crashes on XP SP2 with Visual Studio 2005

  Just trying to install this and all it gets is a Dr. Watson which sends something off to Microsoft :( OK - I installed Windows Power Shell and now get an error message in the installer and can view the log file - this shows that it is failing to download the files (I wonder if it is opening too many file handles) - I have IE7 release installed. PS - you need a dependency on Windows Power Shell!

• Rodrigo Angelo Figueiredo Parallel execution question?

  Can anyone let me know if I can develop the following scenario using WF - I have a requirement where a request has to be approved by multiple people at the same time. The catch is the number of people and who they are is determined only at runtime after looking at the request. So, I will not be able to use a fixed number of parallel branches in the designer. Is there a way to solve this problem in WF directly or do we have to do this manually ourselves like setting up one sequential workflow for each approver Thanks for the help Ashok Ashok - you can use the Replicator activity for this. It can be configured to repeat N activities based on runtime code, and can be set to execute t ...Show All

• Ianmac Need XPS help anyone!

  For the last few days I have been reading everything I can about XPS and merging documents and I am stuck. I have seen the Document merger sample but it really doesn't help especially with all the windows stuff wrapped around it I am just seeking a simple straight forward sample on how to do this. I found this and tried to modify it every way I can but the problem is that the original page for example is in Landscape mode but every time I save it as a new page it put it to portrait mode even though the width and height of the fixed page are correct and the new page variables are correct also. But when I open the new document in the viewer it clips the right side. If they are all portrait then I have no problems at all. How on earth do you ...Show All

• liujj_xujj Black Screen / Freeze after first reboot

  I have spent many hours the past week trying (unsucessfully) to install Windows Vista. I have downloaded and installed all the most recent drivers and BIOS updates for all of my hardware. I have run the Vista Upgrade Advisor and it says that my system should be good to go and that there are no serious issues. The only item on the "Task List" is to download Vista drivers for a wireless networking adapter I have in the system to be installed after. I have tried to do an upgrade from Windows XP and a Full Install of Vista with the same results. I start the install and everything goes smoothly (installer unpacking files and getting ready for installation) until right after the first reboot.

• buster2001 Replace text in XPS documents

  I'm trying to replace text in XPS documents and I've got nowhere. What we're trying to do is replace our old word templates that have bookmarks as placeholders; we use vb6 to replace the text where the bookmarks are. This is so users can create generic documents and merge them with our data from our database. We want to replace this as honestly the current solution isn't that good, but does work, so it's not all bad. I've created an XPS document with bookmarks, can't seem to figure out what makes a bookmark a bookmark in XPS. But really all we would need would be a placeholder like <Address> or <Name> or something and then replace that text with data. Can anyone help or at least point me in the right directi ...Show All
