Windows 7 64bit Registry access using x86 assembly

  
Hi guys, I have an assembly that is complied in x86 release mode. The assembly tries to access  a particular registry key in Win7 the key is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion  -> ProductID(tried to read this value) As the assembly is in x86 it tries to look for the key in SysWow64 node HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion -> ProductID(tried to read this value) When i went through the registry i found that the string "ProductID" is missing (!) .. (may be because i have trial version of windows 7 x64)? I just wanted to ask , is there a way to read registry key (not in wow6432node ) HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion  -> ProductID  in x86 mode? Im using the following  code RegistryKey regkey = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion", false); //reads in wow6432Node for x86 assembly string strProductID = string.empty; if (((regkey != null))) { // Get key Value of ProductId. strProductID = (string)regkey.GetValue("ProductId"); if ((string.IsNullOrEmpty(strProductID))) { //try reading another path for "ProductID" } } return strProductID ; PS:When i complie the same assembly as "Any Cpu" , the above code returns corr

Error reading .config file in Windows Forms app - Access is denied

  
I'm attempting to read a connection string from a .config file in a Windows Forms app on a test laptop. A previous version of the application worked just fine, but now I get a configuration exception thrown - "Configuration system failed to initialize." The inner exception message says - "An error occurred loading a configuration file: Access is denied". The user I'm logged in as is in the Administrators group and there's no obvious problems with the config file. The same config file works just fine on my dev machine so it's not an issue with ordering of the XML. Any ideas would be greatly appreciated.If a response to your question is helpful or answers it please mark it as such!

Using windows authentication to access SQL when using ASP.NET 4.0 via COM+

  

I am using SQL Server 2008 under windows authentication, front end is ASP.NET which uses COM+ to access database.

COM+ components are configured to run as domain user.

When looking through the logs (SQL Profiler), I can see the login name as the configured identity instead of windows indentity.

I have got Website running under "Intergrated Windows Authentication" and database is running locally on webserver.

Web configure contains entry for <identity impersonate="true"/>.

My connection string is

connectionString="data source=db01\test01;initial catalog=test; integrated security=SSPI;persist security info=False; Trusted_Connection=Yes"

Any ideas?

Access to report file denied. Another program may be using it.

  

Migrated from Windows 2000 ASP.NET 1.1 to Windows 2003, ASP.NET 2.0 and had this error. All the forums/MSDN/Blogs says to give Read/Write Access to C:\Windows\Temp folder. Why should we give Full Access to some folder in Production server?? In windows 2000, ASP.NET 2.0 development machine, no files are created when we run crystal reports from aspx pages. Then why in Windows 2003 servers, we need to give rights to temp folder?? It is a simple code

crReportDocument.Load(Server.MapPath("Project.rpt"));

And the code is not storing anything on the disk. Then why should it store the GUID.rpt file in Temp file in Windows 2003 server?? Any alternative is there not to store anything on the disk when Crystal Reports are opened in aspx page??

This is driving me crazy... I cant find the .vsi file for installing the CSS Friendly Control Adapters Project. Does anyone know where I can get this?

The following link: http://www.asp.net/cssadapters/ only leads to the CodePlex wiki where I can download the dll and a partial solution. Essentially, I'm looking for the source code to implement the Menu adapter.

Any help is much appreciated!

Cutting Edge: A New Grid Control in Windows Forms

  

Grid controls are essential in many of today's apps. Until now, though, most developers using Visual Basic® have had to buy third-party components to get an effective, easy to use grid component. The Windows® Forms DataGrid turned out to lack too many features for the average developer.

Security Briefs: Access Control List Editing in .NET

  

Access control lists (ACLs) can be complex beasts, and user interfaces for editing them are incredibly tricky to implement properly. That's why I was really excited when Windows® 2000 shipped with a programmable ACL editor, shown in Figure 1.

Safety in Windows: Manage Access to Windows Objects with ACLs and the .NET Framework

  

Until now, Microsoft did not provide explicit support in the .NET Framework for manipulating security settings. With the .NET Framework 1.x, access can only be granted to users via a series of cumbersome P/Invoke calls. By introducing the concepts of security objects and rules, the .NET Framework 2.0 allows developers to manipulate security settings of objects in a few easy steps using managed code. Want to know more? Read on.

Resource File: Windows Media 9 Series Digital Rights Management

  

If you have an application that handles Windows Media content and you need an effective way to track content usage, Windows Media 9 Series now offers Digital Rights Management (DRM). It allows you to take advantage of the peer-to-peer distribution model and still redirect users back to your app once they have downloaded your content (prior to viewing).
