couldn't open a file extension .cert from browser

Posted By:      Posted Date: October 03, 2010    Points: 0   Category :ASP.Net

 There is a file with an extension .cert sitting on web server. when i tried to access it through URL, i couldn't open it and didn't give any error message also. I verified the file existence in that folder and also i could open it using notepad. Is there any MIME to be added to open this file?

Cutting Edge: Customize Your Open File Dialog


Displaying an Open File dialog is certainly easy in the Microsoft® . NET Framework with Windows® Forms, but the resulting window is not as customizable as when you create it through the Win32® API. With Windows 2000, Microsoft added a nice feature-the places bar, which is the vertical toolbar that appears on the left side of the window to let you select a frequently visited folder.

Moved from WinXP to Win7 - don't see choice to open file in read only or edit mode


I just recently moved from Win XP Pro SP3 to Win 7 32-bit Pro. I am logging into domain X normally. Our Sharepoint 2007 server authenticates only on domain Y. So I start Internet Explorer with "run as different user" and provide my domain Y credentials. All fine. 

In win XP, after I did this, when I click on an Excel file on Sharepoint, I would get a dialog asking if I wanted to check out and edit or open as read only. 

In win7, I don't get that choice. The file simply opens, and I get a bar at the top which allows me to check out the file if I wanted to. 

How can I restore the functionality I used to have, with the dialog for checking out the file before opening it?

Inside the "Default Browser Switcher" extension

You may have already heard of the recently WoVS extension "Default Browser Switcher" (download from Visual Studio Gallery or from Extension Manager inside VS) that helps in choosing what browser you want to launch from VS while debugging your ASP.NET applications. You can start by reading the original post from Scott Hanselman where he describes some interesting inner workings of VS related to how it handles the launching of the VS default browser. Note this is the default browser to be launched from VS which may or may not be your default system-wide browser. If you're brave enough to survive Scott's post then you're ready to enter some even more obscure details: how to package that into an extension for Visual Studio. We started by defining the set of commands we wanted to support and we ended up with ten commands total. That is a "Set default Browser to X" command multiplied by Internet Explorer, Firefox, Chrome, Safari and Opera and a "View in Browser X" command multiple by the same number of browsers. The first set would go into a VS Toolbar and the second set would go into a sub menu whose parent would be a new "View in Browser" command. To author the UI we used the very handy and friendly VSPackage Builder which allowed us to quickly design our 10 commands and place them where we wanted inside VS:   (Yes, that's a DSL for authoring your own custom UI inside
