• 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

• Smart Device Development Webrowser and drawing lines

  Hi, I have a project that includes a webbrowser. I pull up a map (image) from a site and display it. This is on a windows mobile 2003 se box. I would like to draw crosshairs (or two lines) on the screen and cannot seem to associate the drawn lines with the browser or bring the drawn lines to the front of the screen. I cannot seem to do it. Help Thanks Rob It's not possble to draw on a top of the WebBrowser control. What you can do though is to create a custom control that draws image of the map and then crosshairs on a top. You will also need to write code to get the html using System.Net.WebRequest class, parse the html to find the url for the image and download it for drawing in your custom co ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Game Component Design Guidelines?

  Anyone have any suggestions, tips, experiences, etc regarding designing and developing Game Components With the move of the GraphicsComponent to a service (which makes sense), one of my questions is remains: what makes a good Game Component In pre beta 1, other Game Components that were hinted at were a Camera and Fps Counter. In beta 2, would these still be Game Components, or be left at system-level Is the choice as simple as whether or not your would-be-component has an Update method that takes a single GameTime parameter Same goes for IDrawable, if a Draw method with a single GameTime parameter is sufficient, should this be a Drawable Game Component Is it a never-ending debate such as the guidelines for designing Interfaces ...Show All

• .NET Development PROBLEM WITH SPECIAL CHARACTERS

  question...i have a string value in a textbox inputted by the user that contains ' character... and i think that's the reason why i am receiving an error...my procedure is like this "INSERT INTO TABLE(REMARKS) VALUES(' " & TEXTBOX1.TEXT & " ')" please tell me what to do so that my sql statement would accept strings with special characters like the word ADD'L I believe you also need to specify type and size of the parameter.

• Visual Studio 2008 (Pre-release) X509Identity is Internal?

  Hi, i want to write a custom authorization policy that sets a custom IPrinicpal on Thread.CurrentPrincipal. I do something like this if (identity is WindowsIdentity) { ... } When certificates are used for client authentication, the identity generated by WCF is a X509Identity. But this class is internal - so i cannot use "is". Is this intentional or a bug How do I check for X509Identity To support CLR legacy authorization, WCF had to map SecurityToken to IIdentity. There is an explicit/natural map for WindowsToken and CLR's WindowsIdentity. For other tokens, they are pretty much GenericIdentity which doesn’t add much value to IIdentity itself. As far as PrincipalPermission and Thread.CurrentPrincipal are con ...Show All

• .NET Development mouseUp event of vertical scroll bar

  Hi all, Plz tell me hos get MouseUp event of vertical scroll bar of browser in javascript. the onscroll doesnt fire until the user stops scrolling, effectively the same as mouseup.  It also works for the middle mouse wheel that many users use to scroll, which a specific mouseup event on the scrollbar wouldn't detect.  I found a little html on the net that illustrates this point.  If you still think you need the mouseup event please elaborate on why you feel you need to do it that way. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <head> <title></title> <script language="JavaScript" type="text/javascript"> <!-- var zxcTO; function Scroll(){ clearTimeout(zxcTO); z ...Show All
