• Visual Studio Express Editions Refresh Calculated TextBoxes on a Form?

  I'm not sure if my Subject line properly describes my problem, but here it goes. I have a form with several textboxes that are used to enter data. One of the textboxes is bound to a table field that performs a calculation based on the data entered to other textboxes. For example: Textbox1 - The user enters the value '1' Textbox2 - The user enters the value '2' Textbox3 has the formula: Textbox1 + Textbox2 On my form, when the user enters '1' in the first textbox, then '2' in the second textbox, nothing appears in the third textbox. What code can I use so that when the user either enters data in the second textbox, or gives focus to the third textbox, or whatever, that runs the calculation and gives the result, in this case, '3' ...Show All

• SQL Server Security Settings

  I want some users to see some reports on RS, but not see other reports. Is this possible From what I can see, if you are a Browser role you can see ALL reports. Tell me this isn't so... Pete On any RS catalog item you can define the security for that item. If you give a user the Browser role on a report they will be able to see that report. You can map users to roles on a per item basis. There is not concept of a user being a Browser for all items in RS, only for each item as that item is configured. It is perfectly fine for a user to have Browser role on one folder but not on another, enabling them to see all the reports in that folder but not the later. Please see the following article for more c ...Show All

• Visual Studio Unmovable Controls in ASP / VS2005-Sp1

  I am moving a project from VS2003 to VS2005. I created a new Web Site from scratch under 2005 and brought over the ASP pages etc from the 2003 solution.

• Visual Studio Need to 'buy' Report Controls

  Hi I've just started a new job. I used the report controls in my previous job, and my new employers have agreed to buy whatever software I require. Thing is, I'm not sure what I need! I had MSDN in the previous job, so I just installed all the Visual Studio and SQL stuff. I'm planning on using the report controls to design reports based on the existing SQL Server 2000, and some third party access databases. Which version of Visual Studio will get me the report controls Do I need some type of developer edition of SQL 2005 as well I tried asking the local MS vendor, but they weren't sure. Of course, I don't want to buy the wrong thing, and tell my new employers that I wasted their money! Any guidance appreciated Thanks ...Show All

• Visual Studio 2008 (Pre-release) Please explain the difference between Orcas and VS 2005 beta 1

  I am completely confused about what is going on with Visual Studio or even with .net 2.0.  Is Orcas VS 2005 sp 1   When are we finally going to see fixes for the bugs in .net 2.0 (some of which I've personally reported on)   Why are we seeing such a huge lag in between the release of .net 2.0 and a service pack   Why is orcas released only as a virtual image   Personally I find this to be useless in that I can not test anything in a real world scenario.   Could someone please post a single point for information on the future of Visual Studio… i.e. what is coming out next, what is Orcas, what is in Orcas, what does the beta service pack 1 mean etc etc.   The link below says that this is service pack ...Show All

• Audio and Video Development Playing H.264 files on Windows Media PLayer 11 on Vista

  I am not sure if this is the right forum for this question. I would like to play a H.264 video file on Vista. I have installed PowerDVD 7.0 on the system. In XP, Windows Media PLayer 10 uses the PowerDVD to play the video file. On Vista Windows Media PLayer 11 shows an error message that the correct codec is not found, but still plays the video. But it does not seem to be using DirectX as I am not able to create a graph using Graphedit. I want to be able to play the H.264 through DirectX on Vista.
