• Visual C# __DATE__ equivalent

  I'm new to C# coming from a C background. I would simply like access to the build date of my application. In C, I could do this using the __DATE__ macro. How would I do this in Visual C# TIA JeffM hi, i don't know c and i don't know if you can do that useing System.Refliction or not but you can get the creationdate from System.IO class Program { static void Main( string [] args) { string strpath = System.Reflection. Assembly .GetExecutingAssembly().Location; System.IO. FileInfo fi = new System.IO. FileInfo (strpath); Console .WriteLine(fi.CreationTime); } } it will not give you the build date but it will give you the creation date on the client mach ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Device Creation Problem

  Hi, I am a starter to the game development. I planned to create a small program(game) that just initializes a device as a startup. I decided to do it in c#. I have the VS2005 Express Edition to start development. I have also downloaded the DirectX SDK, oct 2006. But the express edition throws an error InvallidCallExcpetion Every time i create a device. This is how i create it.

• SQL Server Converting percent-decoded data, or characters to int

  Say I have a percent encoded expression like www%2emysite%2ecom. An unencoded representation would be www.mysite.com. I have written a tsql regex function to parse an input string and replace any legal percent-encoded substring with its ascii equivalent, returning the unencoded version of the input string. However I'm stuck on one crucial step: converting a percent-encoded substring (ex: '%2e') or its hexadecimal string representation ('0x2e') to an integer. I've tried CONVERT(bigInt, '0x2e') but of course that isn't working. What is the best way to go about this I've been all over the sql server books online, search engines, and other forums. I can't get past this one step. Am I on the right track, or should I look at it a different way ...Show All

• Visual Basic Adding data in one column together

• Visual Studio Team System Data Driven Unit tests and Database Deployment

  Let me first start by saying thank you so much for DataDude! OK, with that said I have a question. Our applications consist of a data access layer that we like to write unit tests for. To best exercise the data access classes we like to use data driven unit tests. In some cases we use the test database as the test datasource as well. Here is the question: when I have a unit test set with the datasource being the database to be deployed in the Database Configuration for the test project everything will work fine if the database exists and has data in the table specified in the DataSource attribute of the test method prior to the test run being started. However, if the database does not exist the test is aborted before AssemblyInitialize is ...Show All

• Visual Studio Report Viewer Table

  Hello, I'm trying to display the table information horizontally insead of down the form. For example, instead of this; A B C D I would like to display two tables beside each other and display the tables and data like this Table 1 Table2 A C B D Or, if there is a way to select (filter) which data is displayed in the table that would work also. For instance, if I could display just the odd pieces of data (the 1st, 3rd, etc, etc) in one table and the even pieces of (2nd, 4th, etc, etc) in the other table that would work also. Is this possible If so, how Thanks in advance, John One option is to follow an approach as discussed in Chris' blog article about horizontal table: http://blogs.msdn.com/chrishays/archive/2004/07/23/Horizonta ...Show All

• Visual Studio Express Editions Using removehandler for unknown events

  Does anyone know if it's possible to remove an event handler when you don't know the name of the event handler sub Let's say I define an event handler: Sub EventHandler() ' Handle the event. MsgBox( "EventHandler caught event." ) End Sub I add the event handler: AddHandler Obj.Ev_Event, AddressOf EventHandler Then if I need to remove the event: RemoveHandler Obj.Ev_Event, AddressOf EventHandler BUT, let's say I don't know the name of event handler (EventHandler). Is there a way to remove an event handler if you don't know the name of the actual sub Thanks! No, I don't think this is possible in VB.NET. In C#, an event is a simple instance of a ...Show All

• Visual C# Inaccurate/Wrong calculations

  Hi, I working on a fairly large project in C#, combining numerous components such as SQL and DirectX. We all, however, seem to have come across a severe problem! We can't do basic arithmetic! For example, in VS.NET 2003, I need to subtract two UTC style time values - eg 11565456546546.1342345566 etc. double large_val1, large_val2; ... double difference = large_val1 - large_val2; Instead of the result I expect (and indeed the result shown in the Watch window during debug for large_val1 - large_val2), I get a servely rounded value instead - that is entirely useless!! Help!! I can do this in a standard command line / console application and everything works fine - why should there be any difference ! I have tried decimal, ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Function found in samples but not docs

  I have found this function in the samples but not in the docs. Does it not draw color on the mesh Where can I find out more about it DXUT_BeginPerfEvent( DXUT_PERFEVENTCOLOR, L "Draw Code" ); Look up D3DPERF_BeginEvent() , D3DPERF_EndEvent() and D3DPERF_SetMarker() in the regular Direct3D documentation. The DXUT code you refer to should just be a wrapper to the aforementioned core API calls. But, as Wessam pointed out, they are for nothing more than monitoring and profiling your D3D applications - an extremely powerful and valuable feature but they don't change the rendering process in the slightest. hth Jack ...Show All

• Visual Studio Express Editions AutoIncrementing UniqueIdentifier column in SQL databse table giving NoNullAllowedException!

  Visual Basic 2005 Express: In my SQL database table, I have a CustomerNbr column. In Database Explorer's table definition it has "UniqueIdentifier" as it's data type, and is set as the PrimaryKey. In the XSD Designer, this field is set as the primary key, AutoIncrement=True. DefaultValue is <DbNull>, but, it won't let me remove this! When I add a record to the DataGridView, it correctly puts a "1" in the CustomerNbr column, but, when I update the record, I get a System.Data.NoNullAllowedException! there are many reasons for it existing. one of our SQL Guru's here did say @@Identity is bad practice and not recommended but rather scope_identity() to be used for the ID ...Show All
