• .NET Development Are there Different variations of framework for the same .NET Framework version?

  I have a product that is used by thousands of users across the globe. .NET Framework has been the life saver by providing a standardized reference environment. The software has been running relatively troublefree until recently. My software does a digital signature check and makes a call to DSASignatureDeformatter.VerifySignature using the SHA1 algorithm. This particular user, from Australia, running Windows XP and .NET Framework 1.1.4322, returns the error: CryptoAPI cryptographic service provider (CSP) for this implementation could not be acquired. Is there an "export" version of .NET Framework Many of my users are from China and other former eastern bloc countries but I have not received similar feedback from those. Wha ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA Book ( In Progress )

  For reasons I cannot exactly put into words, I’ve decide to write a (free) book about how to use XNA.   It is defiantly a work in progress and thus far only includes two chapters and associated source code. I truly hope that my work is advantageous to some people out there. I am in part doing this as a practice towards writing technical documentation.   I am not accomplished in writing instructions for other people that may not have the same level of technical skill sets as myself.   I hope that with this book I learn a whole lot and more in that regard. Granted, if you are a diehard game programmer, what I have written is probably not for you, at least, not yet! Yet I would value your input.   If you feel like c ...Show All

• .NET Development DOA2016.DLL

  Could Someone please tell me I can download a DOA2016.DLL for an old version of Access form OfficeV2. That's the Jet 2.0 DAO library and AFAIK you would probably need to install Access 2.0 if you wanted to legally obtain the file from Microsoft. Otherwise, and I would imagine the legality of downloading the file from anywhere else would be questionable, you can try (at your own risk) the below site. Just make sure to spell the file name correctly when you search (DAO2016.DLL). http://www.webzila.com/ wz=dll ...Show All

• .NET Development How can I detect available SQL server instances in the neighboring network?

  I'll include this in my installation program so that it's easier for users. Any idea Thanks I've tried SMO but still sometimes it doesn't read some available instances. For example, in my machine I have SQL Server Developer and SQL Server Express, SMO gives me just the SQL Express instance. In another case, when I run in some machines with only SQL Server Express, sometimes, it reads nothing. I really don't understand. Could you please explain why Here is my code:- cmbServerName.Items.Clear() Dim dtSQLServers As DataTable = SmoApplication.EnumAvailableSqlServers( False ) Dim I As Integer For I = 0 To dtSQLServers.Rows.Count - 1 Dim ServerName As String = dtSQLServers.Rows(I)( "Server&q ...Show All

• .NET Development Exception handling / Best Practices

  When adding a record to a DB with a unique key, I'm currently checking for duplicates (before I attempt to add) by reading and checking record count. Would it be a better practice to just Add and trap the exception Also: Is there a DataBase of all exceptions that might be thrown I find myself using 'Catch e' and then using Debug to get a clue as to what refinements to make (i.e., 'Catch e as xxx'). I've search (gotten lost in) MSDN, but I haven't found one complete source. MS must keep a DB of ALL exceptions somewhere. Hi, An easy way to choose to use exception or validation is whether an error can be expected and whether your method can do anything if this error occurs. This criteria means that in normal situations, a ...Show All

• Windows Forms no registry keys are created on x64

  I have a Setup Project created by using Microsoft Visual Studio 2005 Version 8.0.50727. This setup project creates several registry entries. The registry editor is used to specify which entries should be created. By setting the project's "TargetPlatform" property to x86 and executing the wizard on 32bit platforms everything works correctly. Ecch registry entry is created.

• Visual Studio Tools for Office Outlook 2007 Add-in woes

  I have been developing/maintaining an Outlook plugin for over a year. It works fine with Outlook 2003, as well as Outlook XP. Unfortunately, during my testing with the Outlook 2007 Beta 2 version, I've run into some problems. It seems like enabling my add-in causes Outlook to throw an exception when it exits. I am using a debugger and Application Verifier to try to solve it, and this is what I've come up with: When the add-in is enabled, I receive the following error from Application Verifier on exit: ======================================= VERIFIER STOP 00000202 : pid 0xC38: Freeing heap block containing an active critical section. 0B65AB98 : Critical section address. 00000000 : Critical section initialization stack trace. 0B658AE0 ...Show All

Each of the computers on the domain have a txt file located directly in the C: drive with the following information in it: Host name: Ip Address: (other information that doesn't matter).
