Start-up problem with Turkish Regional Settings (1 Viewer)

[UNOPARATOR]

The syptom :
MediaPortal main window doesn't show anything other than window borders and main menu strip. There is no GUI. In Windows XP the GUI part doesn't draw at all (just shows what was under the current window position at startup), in Windows Vista the GUI part appears white...

The prognosis :
After installing SVN and looking the source code, I wasn't able to find anything at first. Then I checked the Log directory for any leads and saw this :

2007-09-21 13:04:47.034035 [ERROR][MPMain]: D3D: InitializeDeviceObjects - Exception: System.IO.FileNotFoundException: d:\mediaportal\xbmc\bin\debug\skin\bluetwo\media\newmail[COLOR="Red"]ı[/COLOR]con.png
   at System.Drawing.Image.FromFile(String filename, Boolean useEmbeddedColorManagement)
   at System.Drawing.Image.FromFile(String filename)
   at MediaPortal.GUI.Library.TexturePacker.AddBitmap(PackedTextureNode root, Image rootImage, String file, Boolean& dontAdd) in D:\MediaPortal\Core\guilib\TexturePacker.cs:line 420

   at MediaPortal.D3DApp.InitializeEnvironment() in D:\MediaPortal\xbmc\d3dapp.cs:line 1001

notice the red text (you may have to scroll the code block to the right) that was supposed to be lower case "i" (in Turkish we have upper case "i" as "I" with a dot over it, and lower case "I" looks like "i" without a dot over it) but that crypted text is (I'm guessing that's because the log file is ANSI encoded instead of UNICODE) supposed to be lower case "I" as in Turkish characters...
Then I checked the sourcecode for the use of .ToLower() method.

The solution :
I replaced all .ToLower() methods with .ToLowerInvariant() and that was it.

Suggestion : I know you will find out a better solution for this...
In my opinion it should be better to use case sensitive filenames (as in C# syntax )
or
first try to find the filename as it is (case sensitive) and if no file is found try to find the filename with .ToLowerInvariant() and if still not found try to find with .ToLower() (as the current thread's cultureInfo -Regional Settings)...

The bug exists in latest stable (0.2.2.0), latest release candidate (0.2.3.0 RC2) and also the nightly builds...

As I can finally see the GUI and able to use the program, I must say THANK YOU for your great efforts in such a great and also free product !!!!

So... Any luck to see the fix I offered or any other relating this issue in the next release?

I need some kind of confirmation and/or response from the active delevopers, please.

 

[UNOPARATOR]

This bug still exists in RC3...

UNOPARATOR: I will try to get some devs attention for your fix.

In the mean time you could upload the (complete) patched files to the patches section on sourceforge (based on the latest svn files. That is usually the best way in addition to posting the fix here.

Hi UNOPARATOR,
Thanks for patches, I hope devs hear you and fix that.
Best wishes

No fix yet?

Bugtracker is still showing this as an active bug... come on guys
I had even given a solution to the problem with details on why...

 

[UNOPARATOR]

Here is a blog entry from MSDN about case conversions in .NET Framework & NTFS.
I hope you'll see this making sense in the near future...

Also the same casing problem occurs when configuring TV Server's DB (at least when using MS SQL)...

Here is another piece of information on MSDN about Code Analysis (FxCop) rules: Normalize strings to uppercase
