HTC HD7 – First Impressions

2010-11-01T13:40:00Z

Finally, I got one of the first HTC HD7 devices, that were on Stock at the O2 Germany, exclusive Seller of HD7 Smartphone Model.

First Impressions of Hardware are great except few things like Buttons on the Top and Right side of the Phone (Power, Volume and Camera Buttons), that are a little bit hard to press. Other things like Smartphone Chase, Display, Front Buttons and Speed are just great. User Experiences are more then great and I think that my Investment went to a good place.

Software or better say Windows Phone 7 on the other hand showed that it was worth waiting. It is very Fast, Smooth, and very importantly Stable! Marketplace is getting bigger every day, and there are already some cool Apps that every Smartphone has to have.

Today is a official release date for Marketplace or better said App Hub – Windows Phone 7 App submission, and I am pretty much excited to explore all the upload features that comes.

How to install self-issued Certificate on Windows Phone 7

2010-10-06T09:59:15Z

For all of you that are using Exchange Server with Self-Issued Certificate, when syncing you Windows Phone 7 with your Exchange Account, you will get the Error Message saying Attention is Required and that Certificate is not Signed.

As we know, there is of course no Settings where you can see or change certificates on your Phone, so the easiest way is to install the Certificate over the Browser. Simply send your self a Certificate per E-Mail and open it over OWA, or just put it somewhere on HTTP for download.
Hold your finger for a few seconds on the Link, then open it on the Window, and you will get a screen asking you if you would like to install this Certificate.

After that you will be able to Sync with our Exchange account :)

Silverlight for Symbian - Beta

2010-06-21T12:46:25Z

For all of you Nokia/Symbian Fans, today I found out (have no Idea how I missed this news) that there is a Silverlight Runtime Version for Symbian OS. This is still in Beta, but I found it cool and definitely something to try if you are going to do some Silverlight Apps for Windows Phone 7.

More about Supported Features of Silverlight and my first Impressions, I will be Posting shortly.

Silverlight for Symbian Developers Tools Beta (Visual Studio 2008 SP1)

Silverlight for Symbian Device Runtime (Symbian S60 v5)

MediaElement doesn’t play MP4 Streams on Windows Phone 7

2010-05-17T08:32:00Z

I was little bit disappointed as I saw that the latest Windows Phone Developer Tools CTP - April Refresh doesn’t bring much new stuff that I can play with (Microsoft.Phone Namespace stayed same, no new features, no Sensors in Emulator etc), so I took the Silverlight for Phone.

Silverlight is very powerful in Media Content, so I thought it would be cool if I play a little bit with Streaming Media … aaaaand of course if you are talking about Streaming Media, it is almost impossible not to think about YouTube.com.

So I used YouTube’s API to get the Direct Stream of some Video with following Parameters:

Video ID: j9F4QJK1wFs
Token: vjVQa1PpcFM_C7Hr7areyreHHzULy--u-F7-yaPsOCg%3D
Format: 18 (Video Download Format: MP4)

Gives the Stream URL of: http://www.youtube.com/get_video.php?video_id=j9F4QJK1wFs&t=vjVQa1PpcFM_C7Hr7areyreHHzULy--u-F7-yaPsOCg%3D&fmt=18

Changed the Source of MediaContent Control as floowing:

playMedia.Source =
new Uri("http://www.youtube.com/get_video.php
?video_id=j9F4QJK1wFs
&t=vjVQa1PpcFM_C7Hr7areyreHHzULy--u-F7-yaPsOCg%3D
&fmt=18", UriKind.Absolute);

Sadly but true, current release of Silverlight for Windows Phone April CTP is not showing anything on the Phone Emulator. The same Code/Source on normal Silverlight for Desktop is working perfectly and very fast!
If you change the Source and set some .wmv file (lets say from Channel9), it works like a charm.

I just hope this will change in next Releases or at least on the Release version of Windows Phone 7 Series …

Error generating Certificate Request in New-ExchangeCertificate

2009-02-13T13:17:25Z

It is quite a long time, since I posted something on my Blog. The reason was and it still is, lack of time caused by "combining" the Work and the Study! I will try to make it up soon as possible, but this Problem is something very Interesting, I couldn't find anything about it on the Internet so I thought it could save somebody's time dealing with it!

I came across this Problem with generating a new Certificate Request on Exchange 2007 Management Shell using the New-ExchangeCertificate Method.

You will someday be in the situation where your Certificate (Self-Signed or 3rd Party-Signed) needs to be changed with a new one. Then you are probably using the same command, you used to generate the old Certificate Request, to create a new one like myself and it looks something like:

New-ExchangeCertificate -DomainName mbx.somedomain.com,
edge.somedomain.com -IncludeAcceptedDomains 
-FriendlyName SomeDomain -GenerateRequest:$True 
-path c:\temp\somedomain.local.req 
-privatekeyExportable:$true –subjectName 
“c=DE, o=Some Domain Owner, CN=SomeDomain.com”

But instead of a generated Request file, you get the following error message:

New-ExchangeCertificate : The file or directory 
c:\temp\somedomain.local.req was not found, or 
you do not have sufficient rights to write to it.
At line:1 char:24
+ New-ExchangeCertificate  <<<< –DomainName 
mbx.somedomain.com, edge.somedomain.com 
-IncludeAcceptedDomains -FriendlyName SomeDomain 
-GenerateRequest:$True 
-path c:\temp\somedomain.local.req 
-privatekeyExportable:$true –subjectName 
"c=DE, o=Some Domain Owner, CN=SomeDomain.com"

As you can see, this error message is suggesting that "you do not have sufficient rights to write" on the file, that is absolutely ridiculous. If you are immediately thinking that I didn't ran the Exchange Management Shell as Administrator, I HAVE :) Even more funny is that the Method has created a "new" Request File with 0 KB size, what means that there is of course enough Permissions.

All the time I was suspecting, that there is some other Problem occurred while generating the request file, and as the Result, the Method just returned this completely inappropriate Error Message ... and I was Right! The actual Problem was "IncludeAcceptedDomains" Switch Parameter!
Purpose of the Switch Parameter "IncludeAcceptedDomains" is to add all Accepted Domains from the Organization Configuration > Hub Transport in Exchange Management Console to already defined Domain Names. So, the resulting certificate or request will contain the union of the two values.

After looking at the Accepted Domains in Hub Transport, I saw a one very strange "Domain Name" added as an External Relay, and it was containing only the Wildcard " * ".
Of Course, such "Domain Name" is not valid Domain Name in the Certificate Request and it is also not allowed to be used for Certification.

So if you are getting the same or almost same "Error Messages" using Exchange Management Shell, do not believe it! Obviously, Microsoft's Exchange Team didn't spent much time on a correct Error Handling, so the only solution is to check EVERY single Parameter that you are using, to make sure that everything is correct.

Reporting Services on Windows Vista

2007-12-28T11:18:14Z

For those who have same Problems as I with installation of Reporting Service on Windows Vista (especially from SQL Express 2005 with Advanced Services Installation Package), here are few useful tips:

Missing Features in IIS don't allow Installation of Reporting Services.

If you got the warning message in Installation of SQL Express 2005 with Advanced Services that IIS or Some Features are missing, then you will not be able to Install Reporting Services. Please check your selection under "World Wide Web Services" In "Turn On/Off Windows Features" if you have following options checked:

Common HTTP Features - Static Content, Default Document, HTTP Redirection, Directory Browsing
Application Development - ASP.NET, ISAPI Extensions, ISAPI Filters
Security - Windows Authentication
Web Management Tools - IIS Management Service, IIS Metabase, IIS6 WMI

With help of above named options, warning in the Installation should be gone!
HTTP Error 403.1 - Forbidden Message running /ReportServer

In Internet Information Services (IIS) 7.0, there are new permission requirements for ISAPI extensions that use a wildcard (*) script mapping.
As the Error Message says: "You have attempted to run a CGI, ISAPI, or other executable program from a directory that does not allow executables to run." you need to edit Permissions on the Virtual Directory to allow scripts to run:

Go to Report Server virtual directory, and Click on "Handler Mappings" and then on the right Actions Pane, click on Edit Feature Permissions and Select the "Script" Options.
