• Visual C++ 2 Multithreading questions

  Hi, I am working on a windows application which takes images from IP Video cameras and displays them on screen. There are a few bugs in the code and I am trying to iron them out. I am fairly new to multithreading so I have a few general questions. I have a class which has several definitions of CCriticalSection declared in its header file. (This class is for communicating with the IP Cameras) CCriticalSection m_cSect ;//used to protect ourselves from multithreaded access CCriticalSection m_cSectKillStream ;//to protect the creation/destruction of streams CCriticalSection m_cSectKillStatus ;//protect the creation/destruction of streams & status checks CCriticalSection m_cSectKillHttp ;//protect the creation/destruct ...Show All

• Visual Studio Tools for Office Cannot open VSTO 2005 projects in VSTO 2005 SE

  When I try to open my VSTO 2005 projects in SE, I get the following error: Microsoft Office Outlook 2003 SP1 or newer is not installed on this computer. You must install a version of Microsoft Office Outlook 2003 that supports Microsoft Visual Studio 2005 Tools for the Microsoft Office System projects. I have Office 2007 B2TR installed so have no clue what is going on. Thoughts Hello Misha, I had the same problem with an Outlook AddIn created with Outlook2003 and VSTO 2005. When I want to open that Solution on my Vista + 2007 B2TR + VSTO2005SE -> I can't open that project. This is not a Documentlevel project.

• Windows Forms Quick access to object property

  Hi all, i have an ojbect composed of several other components. It looks like this: Components.Add( new Hm.Components. Transform ( this )); Components.Add( new Hm.Components. Model ( this )); Components should be able to access each others properties through names, without knowing other component types. For now i have a class like this (which is initialized by extracting PropertyDescriptor on the component by using property's name): public class Plug <propertyType> {   object m_cComponent;   PropertyDescriptor m_cDescriptor;   public propertyType Value {     get {       return (propertyType)(m_cDescriptor.GetValue(m_cComponent));     } &nb ...Show All

• Visual Studio Team System The application for project is not installed (project types .rptproj and .dwproj)

  It used to work, but then... Visual Studio 2005 was hummin' and I had a number of BI projects in both Report Services and Analysis Services. I wanted to add source control and decided to install the Team Suite and I did something wrong. I just don't know what it was. In the end, I deinstalled every Visual Studio 2005 (including, of course,the Team stuff)and SQL Server 2005 application, and reinstalled old faithful Visual Studio 2005, but nothing has worked. I'm missing the Business Intelligence project templates completely and I'm guessing that if I had them, I wouldn't get either of the following 2 messages when I try to open existing projects: "The project application for 'c:\...\SOS.dwproj' is not installed. Make sure the ...Show All

• Visual Basic Joining an AD domain with VB2005

  Hi I would like to create a little application using VB2005 to join a computer to an AD domain. I know there are many vbscripts to do this but I'm hoping to make a single gui app to achieve this. Any thoughts You can do something like this, though I have not tested this code, but you get the idea: Private Function IsMemberOfDomain( ByVal ComputerName As String ) As Boolean Dim entry As DirectoryEntry = New DirectoryEntry( "LDAP://yourdomain" ) Dim DirSearcher As DirectorySearcher = New DirectorySearcher(entry) DirSearcher.Filter = "(objectClass=computer)" For Each result As SearchResult In DirSearcher.FindA ...Show All

• Windows Forms Visual Studio Deployment Question

  Hi, sorry if this is in the wrong place but there is no separate "Visual Studio Deployment" forum. Anyway, I was wondering if the "standard" edition of Visual Studio comes with full MSI deployment capabilities. The Visual Studio 2005 Product Line Overview says "yes" next to deployment tools, but when reading reviews of the differences between standard and pro everyone says standard only comes with ClickOnce. Can anyone confirm that the standard Visual Studio comes will the full deployment tools and not just ClickOnce Thanks a bunch, Daniel Yup, Setup projects for building .MSI's are in the Standard SKU. I think marketing got some wires crossed, but I just checked our build s ...Show All

• Visual Studio 2008 (Pre-release) Sending a FileInfo object to client

  Hi. I'm having trouble getting a FileInfo object through to the client. First of all, if I add a operations contract on the server that returns a FileInfo object, it all works like a charm - The FileInfo object is received fine on the client-side. But in my setup, the operations contract returns a custom class that COULD hold some FileInfo object inside. Here's my setup: [ DataContract ] public class TypeDef { [ DataMember (IsRequired = true )] private string description; [ DataMember (IsRequired = true )] private string name; [ DataMember (IsRequired = true )] private object data; public TypeDef( string name, string description, object data) { this .Name = name; ...Show All

• Software Development for Windows Vista Workflow timeout pattern

  How can I build the following piece of functionality I want to do something until a specified condition is true, or a timeout is reached. I implemented it by using a parallel activity with two branches. In one I have a while loop and in the other I have a delay activity with the specified timeout. The problem is that this pattern doesn' work because the fork continues when all the activities in its branches finish. I cannot use a listen Activity because I'm not going to receive any external event Any suggestions Thanks for your answers guys. I even didn't realize that the EventHandlingScopeActivity exists. Now the second part of my original problem. The branch that does the work queries ...Show All

• Windows Forms Placing Shortcut That Can Be Accessed by All Users

  Hi ! I have created a Setup and Deployment project to install my application. I have a help file that I deploy into the Application folder which is under 'Program Files' folder and I place a shortcut to it in the User's Program Menu under a folder. The installation is done by the Administrator and the application is installed for 'ALL USERS'. Everything else is fine but when some other user logs on to the system and tries to access the help file from the User's Menu by accessing the shortcut, the help file does not open. Instead the application begins to reinstall somehow from the original location. I would like the help file to be accessible to all users. I know there is an option to use 'Custom Folder' during setup in the 'File Sys ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Installing old sdk over new one

  I recently installed the August 2006 DX SDK, but I would like to install the 2003 release for the VB docs. Would this be fine, or could it possibly screw anything up If so, what should I do EDIT: Well, I just installed the docs from the old SDK and everything seems to work fine.

  I am writing an application for a Windows Mobile device using C# and .Net Compact framework. I need to obtain the system timezone or timezone that the user specifies in the Settings/Date and Time area. System.TimeZone is an abstract class and if I do try to call System.TimeZone.CurrentTimeZone I get a NotSupported exception. I have also tried p/invoking GetTimeZoneInformation() and also received a NotSupported exception. I went to pinvoke.net to see what methods are available under coredll.dll and GetTimeZoneInformation is not there, so I have no idea how I am to get the timezone.
