• .NET Development Data Access Layer with SQL Server 2005 and ASP.NET 2.0

  I have a web site with a main area for all users and two subwebs (virtual directories) for user groups. My question is: When creating a data set should I duplicate the .xsd file in each of the subwebs Is there another way to use the same .xsd file for the entire web and each of the subwebs Should the data set be pulled out of the home web and moved to a seperate class library Am I trying to kill a fly with a hammer Thanks for your replies. I recommend you to read these tutorials about three-tiered architectures with ASP.NET at http://asp.net/learn/dataaccess/default.aspx tabid=63 They are very high quality articles written by the Scott Mitchell. ...Show All

• Windows Forms Listview Column Widths

  Hi, I have inherited a program with a listview with various columns, only some of which are visible to the user. Problem is that the user is able to resize the columns of the 4 columns they can see, but what is happening is that they occasionally get to see the data of the columns with width set to zero. Know I haven't explained that well, but basically what I am after is a way to "lock" the column width of certain columns but not others. Any ideas gratefully received, or confirmation that it cannot be done , if that is the case... but then I will have to bash my head against the wall!!! Thanks       You can do it by handling the ColumnWidthChanging event: Pr ...Show All

• Visual C++ Why doesn't PDH work?

  Hello, I've been trying to develop an application that reads the CPU load from the computer and the free RAM memory available. To do so, I was primarily thinking about using the PDH interface, since we are building to Windows Server 2003 and Windows XP, both of which already come with the PDH.dll. I downloaded the platform SDK from Microsoft's site, and I am using Visual Studio 2005. My dilemma is, every time I try to compile the source code, it gives me several errors, even with example codes taken from Microsoft's site. It gives me several unindentified objects in _main (it cannot understand/localize the commands, datatypes and so on). I don't understand why. I tried copying the pdh.h and pdh.lib to the main i ...Show All

• Visual Studio 2008 (Pre-release) Table per type (subclass) inheritance

• SQL Server Overlay of textboxes are not rendering properly

  In the page header I have a rectangle that has 2 textboxes on the same line and both are the full length of the page. One textbox has text centered and the other has text right justified. When I render report in Studio or print it, the text appears on the same line and justified like I want, but when the report is rendered when I call the report by URL, the textboxes wrap, like it's taking the width of each textbox in account. Has anyone seen this Any suggestions on how to overlay text on the same line and the text keep their own individual characteristics I am having this problem too. I have a template with a standard heading including one image and 4 textboxes. The template includes a boolean parameter ...Show All

• Visual C++ Help with twister

  I have been looking on the net for random number generators and found something called "Mersenne Twister" on this page: http://en.wikipedia.org/wiki/Mersenne_twister . And there you find som pseudocode that I don't fully understand. For example, how do I write this line in C++ : MT[ i ] := last_32bits_of((69069 * MT[i-1]) + 1) And from the second function, how do I write the following code in C++ y := 32nd_bit_of(MT[ i ]) + last_31bits_of(MT[i+1]) Is this the most efficient way of checking if a number is even : if(x % 2 == 0){do something...;} The most confusing parts here are "last_32bits_of", "32nd_bit_of" and "last_31bits_of". I don't really understand what that mean at all. I a ...Show All

• Visual C# Listboxes - drag drop & reorder

  Hi, I'm new to C#. Edit: Nobugz helped me get this worked out in VB2005 and need to convert to C#. Maybe it can benefit everyone on this forum. Listbox1 is source & is filled with items.

• Game Technologies: DirectX, XNA, XACT, etc. Rendering To Textures in Beta2

  I used Texture2D's heavily with the usage RenderTarget, however in Beta 2 its like a whole new API. I understand that Surface no longer exists and RenderTarget/2D should be used. The problem is, the whole mentality is backwards compared to what im used to. From what I see I should create a RenderTarget2D and set that as a render target, then do rendertarget.GetTexture() if I want to set it. Thats fine. However, how do I copy between render targets There is no StretchRect or equivelent function I can see, which I used alot before. Surely I dont have to go about getting a texture, setting it, creating a 'copy' effect, setting a new render target, resolving the new render target just to copy from one to another Is there no alte ...Show All
