• Silverlight (formerly WPF/E) Pixel based graphics

  Does the Feb CTP adds any support for doing good old pixel based effects The vector stuff is cool but for some things pixel based effects are mandatory. If not, is it planed for a future version :-( I'm not asking for a full fledged pixel based library like GDI+. Just some way to show and edit pixels directly like BitmapSource. I hope such a basic support gets added soon. ...Show All

• SQL Server Show / Hide Parameters on a Report

  Is there any way to get the parameters to remain visible after clicking on a report link Currently, when I click my report link and pass parameters, the new report loads with all the parameters hidden even though they normally appear fine when you go to the report straight. Now, there is a way to make them visible by clicking the "Show / Hide Parameters" button on the far right of the screen. However, I would really like to hear of a way to automatically keep my parameters visible after clicking on a report link. This is especially useful since most general users won't know to click the "Show / Hide Parameters" button and won't be able to specify new parameters after clicking the report link. Any ideas Thanks!!! ...Show All

• Visual Studio Express Editions get string from string

  Hi I want to know how to get a string from a string. Let me do an example to understand better. I have "> Bogas Corp acabou de entrar." I want to keep just "Bogas Corp". It has to work dynamically because "Bogas Corp" is dynamical, it can be a different name. "> " and " acabou de entrar." are fixed, they don't change, so how can I get what’s in the middle of them Please help! Sincerely Bogas Corp Hi, you can use the methods of the string class to find substrings and extract them. With myString.InexOf and myString.LastIndexOf you will get postions where your searched substring is and with myString.Substring(start,end) you can get ...Show All

• Visual Studio 2008 (Pre-release) MediaElement is playing HD-movies slow in RC1

  I've just upgraded my system from June CTP to RC1 of .NET 3.0. Rebuilding my projects worked without any problem but when i try to playback a HD-movie(720p) in a mediaelement i get unacceptable framerates. In June CTP the exact same movie worked perfect and i can't think of anything else that has changed in eighter my system or project that might affect videoplayback.

• Windows Forms Treeview - Problem with multiple languages

  Hi, I have an event, treeView1_AfterSelect and I do something based upon treeView1.SelectedNode.Text property. I compare that property with something say "Messages" and it works fine. The problem came up when we decided to globalize the application. I can no longer make the same comparison because Messages wont be messages in lets say my spanish GUI. I dont know how to make the comparison now, I went through string.Compare() but am afraid thats not of much use. Any pointers on this would be appreciated, Thanks !! If you're doing something like: if(treeView1.SelectedNode.Text == "Message") I would suggest moving the "Message" into your applications settings as a string t ...Show All

• SQL Server Simulate "Grand Total" but with functions: AVG, MAX, MIN.....

• Software Development for Windows Vista kbfiltr example in ddk doesn't work?

  I have been using a modified version of the kbfiltr DDK example that I have been using to route data from a HID keyboard MSR up to user level for an OPOS "driver" for some time now on Win2k and XP. It works on 2k and XP but becuase I use IOCTLs it won't run on Vista. As I inderstand, IOCTLs are no longer allowed between user space and kernel space any more Installing it, Vista claims that the driver is not compatible with Vista, I believe this is the reason, but anyway... So I am starting over with the WinSDK/DDK sample "kmdf/kbfiler" This contains an alternate method of user level communication. However, after building the .sys file and the test program, then installing the filter driver on the MSR device, both t ...Show All

  What is my problem When I try to make a simple print test I can not get access to the Printer library in the My namespace. When I write My.Computer. a list comes up with Networks, Ports, Registry, Screen and lots of other stuff but not Printers. Why I shouldn't have to install a printer just to write the code I have Adobe PDF as my default printer right now but that shouldn't matter. I also have downloaded VB Express recently and I am quite certain that it is the most recent one.

The whole My namespace was for .NET 2.0 which basically is a "shortcut" ...Show All
