Windows application problem targeting any cpu

Posted By:      Posted Date: October 14, 2010    Points: 0   Category :.NET Framework

We currently have a visual basic 2010 application that uses a backend microsoft access 2007 accdb database. Our users have recently reported that since upgrading to office 2010 they can not connect to their databases. We had specifically targeted our application to x86 as the database drivers for 2007 are only 32 bit.

On our developmnent we have now installed Office 2010 64-bit and switched our application to target any cpu. On first doing this the application seems to crash during closing a connection to the database given us no debug information, after looking on search engines  for any helpful information we did find an interesting thread that pointed out 2010 x86 by default. Further investigation has led us to believe it is not the access database drivers that are causing the issue but something else that is specific to 64-bit. We have removed any dlls that we are currently referencing that may be using any unmanaged code, but still get the same issues. Are there any known problems with developing Windows database application 64 bit in Studio 2010 any help or guidance would be appreciated.

Application Architecture in Windows Forms 2.0

Applications have special support in Windows Forms. For starters, you can manage and tailor your application's lifetime, and, when the work flow is disrupted by an unhandled exception, you can choose from several methods of response. Then, there are several application models that you can employ, including Single Document Interface (SDI) and Multiple Document Interface (MDI) applications, each of which can support either multiple-instance or single-instance mode, the former the VS05 default and the latter requiring special consideration. All applications, however, can discover and use a wide variety of information about the system and environment they execute in.

Application Architecture in Windows Forms 2.0-Single-MDI Applications

Consider an MDI application like Microsoft Excel; files opened from the file system (by double-clicking) are all opened as separate child windows within the parent Excel window.7 For the first instance of an MDI application to open a new child window to display the file that was passed to the second instance of the application, the second instance must be able to communicate with the initial instance.

Problem making Role based Menu in MVC application



 I want to make Rolebase menu in MVC such that if user doesnot have permission for some action then that Action name shouldnot be shown in the Menu.

 I have used Controllers for post, thread etc.In each controller there are some actions that are using [Authorize(Roles)] attribute

 In the code, Authorize attribute is applied to Controller class, but my requirement is of Applying Authorize attribute to some actions in controller so that some are available for all users and  some links are available rolewise.Now what is the solution for that?



SqlServer - Windows Account to install Application from Gallery


Referring to this tutorial: http://www.asp.net/webmatrix/tutorials/download-and-install-an-asp-net-application

I selected umbraco cms and got this wizard:

I already have Standard Sql Server 2005 on my machine which I wanted to us for above DB and not SqlExpress.

I did not remember "sa" account pwd nor I use explicitly any account to connect to my Sqlserver. I use Windows Authentication account i.e implicit authentication. So I created new account and gave all rights and used it in the above wizard and was able to install the database after some struggle.

My question is: What if I want to use my Windows Account to install the database above? Why the wizard don't have any option to use Windows Integrated Authentication?

Note: I can create the DB with external user I created, just looking specifics for using Windows Authentication for above installation.

Windows Forms: Give Your .NET-based Application a Fast and Responsive UI with Multiple Threads


If your application performs any non-UI processing on the thread that controls the user interface, it may make the app seem slow and sluggish, frustrating users. But writing multithreaded apps for Windows has long been restricted to C++ developers. Now with the .NET Framework, you can take advantage of multiple threads in C# to control the flow of instructions in your programs and isolate the UI thread for a fast and snappy user interface. This article shows you how. Also, it discusses the pitfalls of multiple threads and presents a framework for safe concurrent thread execution.

Designer crashes sometimes because application path becomes C:\Windows\system32

Sometimes VS crashes as it seems to execute the WPF designer in its directories or C:\Windows\system32. Sometimes it works fine as we can preview saved settings in the Designer. I have set application path as follows : ConfigFile = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "mixer.ser");<br/> When VS crashes I accept to debug it, the exception is : {"Access to the path 'C:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\\mixer.ser' is denied."}    System.Exception {System.UnauthorizedAccessException} ... or c:\windows\system32 Any ideas on how to fix this ?   Thank you !

Wickedly Strange .Net WPF Performance Problem Dissapeers with Windows 7 Performance Monitor Open

Hello Everyone, I have been developing one large and complex WPF application for 13 months now, all is going well and especially tonight as I now have some sort of clue or hint to what I have been seing now for quite some time.  Here is the rundown. 1) Running on i5 processor with 4GB RAM and Windows 7 2) The application was developed all in .Net 4.0, WPF C#. 3) It is heavily GUI intensive and also uses Entity Framework Detached for Database Access. 4) Is multi-threaded / multi-tasking. I am a nutcase when it comes to testing.  Since my graphical application heavily depends upon performance and determinsm (please somebody don't start with the C++ vs .Net on here) and has been performing great FOR THE MOST PART.  Every once in a while, I see that the application runs into the weeds for 5 or 6 seconds and the interface is unresponsive.  I have this thing tuned finely too.  Well now toward the end of development I have finally had to face that bug so to speak.  I can force it by clicking spastically on my buttons causing an event storm and making the system update the GUI.  SO!  Great start, I can now cause the problem on a regular basis (for you youngsters that is actually a good thing)!  Alright, so I start with the easiest investigative tool, CNTRL - ALT - DEL into Windows 7 Performance Monitor.  As you can tell from
