• Game Technologies: DirectX, XNA, XACT, etc. Math.Abs inner workings?

  I'm trying to decide how to structure my code based on Math.Abs function. Does it just flip the signed bit to make the number positive Or does it check for a negative value and if found, multiply the number by -1 Yes. Just to point out, though - implementing your own version of things like this is a bad idea. Computers (in general) do not use signed-magnitude representation of integers, they use 2s complement. Thus, flipping the sign bit doesn't actually produce a value with the same magnitude. Of course, you could be operating on a platform where that does work. The only way to ensure that your code works everywhere is to use operations that don't depend on the bit-representation of numbers. Either thing ...Show All

• Visual Studio Problems loading August MSDN Library

  During the install of the August MSDN Library, my syste blue screened and rebooted. After coming back up I've attempted to restart the install, repair and remove the library and I always get the same error message: The wizard was interrupted before MSDN Library for Visual Studio 2005 could be completely installed. Your cmputer has not been modified. To complete installation, run setup again. Click Finish to exit the wizard and run setup again. How do I get past this so that I can complete the install Karl Jamie, I am glad your problem is resolved now. Thanks for providing steps that fixed your system.

• SQL Server Send data to a network printer from a CLR trigger

  Hi, Does anyone know how to print from a CLR trigger Cheers James Hi, it really depends on what you want to print. If you want to create your own "report" from the CLR program you might want to use the http://msdn2.microsoft.com/en-us/library/system.drawing.printing.printdocument.aspx PrintDocument class for this. Otherwise, if you want to print some known file type like a acrobot you would have to use another method to print the data. HTH, Jens Suessmeyer. --- http://www.sqlserver2005.de --- ...Show All

• Visual C# foreach in C#

  Hi, I use C# in ASP.NET . 1. What is "foreach" and how can I use it 2.How can I have a collection of controls that are in a web page and use it bye foreach is a loop to iterate through some collection or arrays just like we do with for, do/while and while loops what foreach provides us is the safety of not getting out of range when iterating throgh some collection. The other things about foreach loop as compare to other loops is that it provides readonly access to objects accessed through it. When thinking about the proformance point of view foreach is not as good as other loops in its efficiency. I hope this will help. Best Regards, Rizwan aka RizwanSharp ...Show All

• Visual Studio Team System Team Foundation - portal create failure - wsdl related?

  Hi - I have a Team Foundation environment that was upgraded from RC1 to RTM. Everything has been working flawlessly with the exception that I can no longer create new team projects. When I try to do so, I get an error when it tries to create the portal. I've looked at similar postings here but no solution so far. I have tracked the problem down to what appears to be maybe SOAP related. Specifically, I can browse to any of the .asmx files in the _vti_bin vdirectory under the default web site. But if I click on the description, I get back a 404 error. This only appears to happen for the vdirectories related to Sharepoint. I've traced this into the wswsdl.aspx file in the same directory and it appears to be throwing an exception when it tr ...Show All

• Software Development for Windows Vista Getting WLX_NOTIFICATION_INFO values like htoken and hdesktop

  Hi All, Since in VISTA winlogon notification is not there, I have written COM+ service which uses ISensLogon Interface to receive logon, logoff and startshell notification similar to winlogon notification in previous versions of windows. Earlier winlogon notification used to give WLX_NOTIFICATION_INFO structure pointer. But using ISensLogon interface i get only login username. Since I am creating a service(ie i am in system context) i am not finding ways to get "Handle to the user's token" and "Handle to the desktop that is currently active" which are part of WLX_NOTIFICATION_INFO structure. If any one knows please let me know how do i go about doing this. Thanks in advance -Praveen ...Show All

• Software Development for Windows Vista Events not reaching Workflow...

  Very likely I am not doing it right but cant see the obvious. I used the "Communicating with the host application" lab exercise document as the base with some changes, I have host app (implemented as windows service) that, based on config, loads a couple of assemblies implementing certain local services. The app first registers an instance of ExternalDataExchangeService with the WF runtime which it then passes to the assemblies implementing local services. The assemblies then register instances of their respective local services with the external data exchange service. These satelite assemblies also expose remoting i/f which allows other app to deliver events to be routed to the workflow instances via the local service ...Show All

• Windows Forms Master/Detail with subform

  Rather than have a master/detail based on a DataGridView (which only presents rows and columns), I would like to have a master/detail which is handled with a form and subform (with a Panel, GroupBox, or Form acting as the subform).  This way, I can position controls on the form and subform (corresponding to data columns)  in a non-tabular fashion . Assuming this can be done (and perhaps even if not), could a permo-FAQ be created that addresses this matter   In this forum, it seems reasonable to address this "other" common paradigm for handling master/detail.

• Architecture critique requested on thin Data Access Layer

  I have devised a way to save tons of code by calling stored procs with a single web service method, which takes a DataSet parameter, containing a DataTable with the name of the stored procedure and column names matching the parameter names, and row(0) contents matching the values to be passed. I have further simplified matters by making all parameters varchar, so a call from my client looks like: Dim paramVals As String() = { myString1, myString2 } Dim ds As DataSet = oneWsMethod("storedProcName", "param1,param2", paramVals) ... Dim params As String() = { this1String, thisOtherstring, thirdString } ds = oneWsMethod("anotherProc", "p1,p2,p3", params, usingTransaction:=True) My o ...Show All

• SQL Server Conversion failed when converting the varchar value

  I keep receiving this error: Conversion failed when converting the varchar value 'INSERT INTO temp_tableZ (Customer_Category_Key, Item_Category_Key, Sales_Rep_Key, time_member_key, Revenue, Fiscal_Year ) select Customer_Category_Key, Item_Category_Key, Sales_Rep_Key, ' to data type int When running the code below.
