• SQL Server Custom Semi-Transparent bar charts?

  I know that SSRS 2005 has a built-in semi-transparent color chart palette, but I'd like to define my own custom color semi-transparent palette. Brian Welker's blog ( https://blogs.msdn.com/bwelcker/archive/2005/05/20/420349.aspx) has a terrific post on how to create your own custom color palette, but it generates solid colors. How can it be tweaked to create semi-transparent colors Is there another function that needs to be created to define the transparency of the color palette Thanks in advance, Pete Transparency is more than possible with ANY system palette or custom palette. The trick (work-around whatever) lies in modifying the 'alpha' component of the colour for each series in the chart AFT ...Show All

• Visual Studio 2008 (Pre-release) Does kerning really work ?

  I've read on the web that WPF comes with great typographic support, including kerning. But anything I've tried, I couldn't manage to make it work. I've used several fonts (although I know for sure that the font I want to use has kerning pairs). I've tried putting explicit Typography.Kerning="True" on almost all my XAML elements. After spending a lot of time, I went to Expression (both GD and ID) to make some additionnal experiments, but none of those programs could produce kerning. While something like Adobe Photoshop can. No success. Is this a bug, a limitation, or am I just doing something wrong Any help is welcome. As a follow-up, I finally manage to get the text rendering I wanted. How By ...Show All

• Visual C++ C++ design capabilities

  I want to create software that allows the end-user to create multiple copies of their own buttons on a scanned map which buttons can be rotated 360 degrees and linked to a database. I thus need libraries of code for rotate and also zoom functionality that I can incorporate. Can I get this done with C++ or any of the other Visual Studio programs If not, what software do you recommend Use .NET. C++ is too low level for your requirements. If you aren't motivated in learning C++ and are instead more interested in putting together an app quickly, then I would recommend creating a C# based WinForm app and looking around on the net for image manipulation libraries. ...Show All

• SQL Server OO Database Design performance question

  I am hoping someone has had a similar table design scenario and has a slick solution that i am not thinking of. Basically I have the following tables (kind of OO based design in this case). Create Table Entity (EntityID int, EntityTypeID) Create Table Company (EntityID, CompanyName) Create Table Contact (EntityID, FirstName, LastName) Create Table Group (EntityID, GroupName) Basically an Entity can be a Company, a Contact or a Group based on the EntityTypeID The trick becomes when I get an EntityID is how to get the name of the Entity in an efficient manner. You can make a view that does a Union to all three tables like such... select CompanyName as Name from Company union all Select FirstName + LastName ...Show All

• Visual Studio Tools for Office F5 -> "File already exists"

  Hi, I'm new with VSTO development and been experiencing this really annoying issue. Everytime I hit F5, it launches the Excel document associated with the project. However once Excel launched, it often (not all the time but quite often) gives me the "File already exists" error message. I then must open the Excel file manually from File -> Open. Everything works then. Strange that it doesn't do this all the time, just occasionally. Any ideas Cheers, Victor Hmm didn't have time to try. But I found a 'workaround'. If I leave my original Excel file open, everytime I hit F5 from the Visual Studio it'll re-open the file but this time telling me the file is opened by another user (me) and if I want to open it as &q ...Show All

• Visual Studio Tools for Office VSTO Outlook Add-In not loading outside of VS2005

  I created a Add-In project using the Add-In for Outlook 2003 project template. I started with some simple code to test functionality and then continued to create the add-in I wanted. During development I always tested using the debug in VS2005. I never had a problem with it appearing this way. However, now that I am trying to deploy the Add-In, I am unable to get the Setup project to work. Even on my own machine, once the setup project is installed, the add-in does not load. I created a simple MessageBox.Show("hello") add-in to see if I had introduced the issue. However, this add-in behaved the same. I could always run it in VS2005; however, when installed from the setup project, the add-in would never load. Another str ...Show All

• SQL Server Query much slower on 2005 compared to 2000

  We have a database developed using SQL Server 2000. We are in the process of testing it on SQL Server 2005. So far i've not done much testing but it has become apparant quickly that quite a lot of queries are performing much slower in SQL Server 2005. I am currently trying to figure out why a particular query is not performing well. One SQL Server 2000 it runs in around 6 seconds. On SQL Server 2005 it takes around 50 seconds. The query is this... SELECT StartBase, StartPoint, PickupPoint, PickupInstructions, SingleJourney, Destination FROM vwJobs WHERE StartDateTime BETWEEN '2006-09-01' AND '2006-09-23' vwJobs is a view in our database. The view includes many UDF's and also has a UNION which combines two seperate table structures ...Show All
