When i check in the properties and set it to true; i get no error.

  Hi, We are preparing a lite version of our product (Outlook 2007 VSTO addin) and we need to add Outlook 2007 and Office 2007 PIA in the launch conditions.

• Visual Studio 2008 (Pre-release) Data binding to a control's own properties - best practicies?

  Hello, I'm just getting started with WPF and Xaml, and I'm trying to figure out the proper way of dealing with what I thought would be a common situation. If I have a control, for example something simple that is supposed to just show the name of a colour on a background of that colour: <UserControl x:Class="WPFTest.Test" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <TextBlock Text="{Binding Path=Color}"> <TextBlock.Background> <SolidColorBrush Color="{Binding Path=Color}"/> </TextBlock.Background> </TextBlock> </UserControl> Firstly, is ...Show All

• .NET Development Can I store string in dataset?

  Probably there are easier ways to do what I want to do but here is my requirement. I need to store some tables as well as some strings in XML file for my application as a configuration. Currently I use dataset.WriteXML() method to persist data and retrieve data for my table but having problems with storing string values. I had to create dummy table in my dataset and populate with my string data (each string in different column). This is pretty ugly and I wanted something easier and more elegant to implement but I don't want to do a lot of XML plumbing. Basically what I need is ability to save configuration data for application to XML file. Data consists of tables and some string values. I know there are easier ways to do what I'm ...Show All

• Software Development for Windows Vista reading event log; compatibility xp and vista

  I have posted this on the vista sdk forum. As this is also a compatibility issue, I am posting this on the compatibility forum also. I have an application in unmanaged VC++ working successfully on XP. However when I run the application on vista I get errors. The application creates an event, and uses the NotifyChangeEventLog sdk function to notify my application of any new event being written to the windows event log. I then use the ReadEventLog to read the event log record. All these functions are supported on the Vista and works fine. However, things get murky hereafter for the vista. I use the registry to read the EventMessageSourceDLL which then provides me the event description. However this part is not working on Vista, ...Show All

• Visual C# How do I get win32 and x64 configurations in the same project?

  Hi, I'm fairly new to VS2005, so hopefully this is an easy question to answer. I have a solution with several projects in it. The solution already has a 'win32' solution platform and the projects all have 'win32' project configurations for both Debug and Release. What I now want to do is add an 'x64' configuration to each project. I *thought* that I could do that as follows: create an 'x64' solution platform and create an 'x64' project configuration for each project. Then, in the Configuration Manager, I select 'x64' as my 'Active solution platform', and for each project select the 'Debug' configuration and set its Platform to 'x64'. Repeat for the 'Release' configuration. However, if I change the 'Active solution platform' back to 'win32' ...Show All

• Visual Studio Express Editions Interop question

  Hello I have a question about C# express, apologies if it's been asked before, I searched the other posts in vain. Is it possible to create a class library dll in C# 2005 and use it in a C# 2003 project When I try to reference my 2005 project dll from 2003, I get a "reference could not be added, not a valid COM component or assembly ...". I haven't tried going the COM route (I'm new to C#) as the examples I've seen had to do with sharing 2005 with vb6 and the like. Any help anyone is willing to provide would be very much appreciated!
