EventType clr20r3, P1 devenv.exe, P2 9.0.30729.1, P3 488f2b50, P4 system.drawing, P5, P6 488

Hi,I am facing a strange issue in Visual Studio 2008 Standard SP1, when using WPF Designer (even without using the Designer tab, only XAML tab). Visual Studio crashes very often, without any apparent reason, and in various ways, for example: exits instantly, the IDE displays corrupted UI, when begining compiling it stops responding.There are two new Event Log entries after this: EventType clr20r3, P1 devenv.exe, P2 9.0.30729.1, P3 488f2b50, P4 system.drawing, P5, P6 4889dec2, P7 33d, P8 18, P9 system.outofmemoryexception, P10 NIL. .NET Runtime version 2.0.50727.3053 - Fatal Execution Engine Error (7A2E0F92) (0)Worth mentioning:- computer has Windows XP SP3 with the latest updates installed- it crashes on other computer types too- the project has quite a large number of UserControls - it appears that if opening a XAML file with the XML editor instead, it works ok- on other WPF projects it also works okDoes anyone have an ideea why is this happening and solutions? Thanks

Working with System.IO.Path static class

Hello everyone. Today, I was exploring the System.IO namespace in .NET 4.0 on an ASP.NET web application where I came to few changes, comparing with the previous versions of .NET, related to the System.IO.Path static class. The Path class contains the same method names in .NET 2.0, 3.5 as well as 4.0, only (in .NET 4.0) new overloads are added to System.IO.Path.Combine() method. In the following blog post, I will show the usage of few methods belonging to the System.IO.Path static class, as well as, the changes in Combine() method added in .NET 4.0. Besides the first method that is available in the previous versions for combining two string paths, now in .NET 4.0 you can combine unlimited strings to the path. Note: For testing purpose, on your web application root, create folders with name Files, Files/SubFolder, Files/SubSubFolder and add three text files: text1.txt (in Files), text2.txt (in Files/SubFolder), text3.txt (in Files/SubFolder/SubSubFolder).   Here are few examples:             string path1 = System.IO.Path.Combine(Server.MapPath("Files"), "text1.txt"); //this will give the path to %WEBAPP_ROOT%/Files/text1.text -             string path2 = System.IO.Path.Combine(Server.MapPath("Files"), "SubFolder", "text2.txt"); //this will give

XmlSerializer: Serialize an array of System.Drawing.Color

Ok,  here is my problem... I am building a UI configuration tool that utiliizes a PropertyGrid.  One of the properties is a indexed list of Colors contained in an array: CategoryAttribute("Style"), DisplayName("Data Set Colors"), DescriptionAttribute(""), XmlArray("SetColors"), XmlArrayItem(ElementName="Color",Type=typeof(SColor))] public Color[] SetColors { get; set; } The beauty of the PropertyGrid is it knows how to handle this Poperty and properly handles array and list of Colors. BUT...   As we already know in order to serialize a Color,  we have to use a surrigate property,  which is very unfortunate, and I fear is one of those little thing MS just overlooked.  (I understand it is actually a structure and not a class and has not default properties from which to get type info from.) I am really amazed that when I do serialize the class,  the XML is soooo  close to what I need,  its just missing the actual color value data: <AppGridColumnConfig xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Name>Label</Name> <SetColors> <Color /> <Color /> <Color /> </SetColors> <IsDefaultEditable>false</IsDefaultEditable> <IsDirtyCheck&

Installation troubble with Silverlight but VS2010 loads without errors. 2. Now I wanted to try out this things with a full aero window and found a nice and simple code snipplet on the MSDN .NET FW4 Extend Glass Frame Into a WPF Application So I made this short changes in my first source code and I'm getting the strange message: Error    1    The type or namespace name 'Drawing' does not exist in the namespace 'System' (are you missing an assembly reference?)    D:\Projekte\Selfmade\Software\CAS_Information\CAS_Information\MainWindow.xaml.cs    19    14    CAS_Information I found a lot of c# code with a using System.Drawing; but on my installation I dont have such a namespace. What the heck is wrong there?   Windows 7 x64 - VS2010 RC

System.Drawing.Image.FromFile crashes for tiff files on 64bit system


The following pice of code runs fine on my development machine (win7, 32bit) but ends with Exception on the server (Win2008R2, 64bit).


        static void Main(string[] args)


            Image image = Image.FromFile(args[0]);





The exception will be thrown for TIFF files (from other sources) but ie not for PNG files.

I was wondering why the test program above works fine on my Win 32bit machine with .NET 4 but not on my 64bit machine with .NET 4.

Any help appreciated.

Web Service to inherit from a Custom Base Class that inherits System.Web.Services.WebMethod instead


Hi All,

Recently, I tried to get my Web Service class to inherit from a custom base class that inherits from System.Web.Services.WebMethod instead of the System.Web.Services.WebMethod directly.

However, I've been getting Error 500.

Public Class Service1
    Inherits BaseClass
    <System.Web.Services.WebMethod()> _
    Public Function GetSessionID() As String
        GetSessionID = Me.Session.SessionID
    End Function
End Class


public class BaseClass
    Inherits System.Web.Services.WebService

    public property Property1 as string
    public property Property2 as string

End Class


Please kindly assist.

Thank you in advance.

'System.Drawing.ToolboxBitmapAttribute' threw an exception. .... since MS won't fix it, does anyo


I'm hosting a few .net sites, some collapse with this error on an almost daily basis. I've moved the sites between servers, but sites on all the servers seem to be affected, so it is not just a bad install.

This problem is acknowledged by MS and they have a fix here:


But they don't provide the fix they talk about.

Does anyone have any way to resolve this that does not need Microsoft (since Microsoft clearly aren't bothered to fix it)?

System.Drawing.Bitmap.SetResolution is completely broken on Windows 7


Bitmap.SetResolution does nothing on Windows 7. It works fine on XP and Vista. This code demonstrates the problem:


            foreach (string file in Directory.GetFiles(@"C:\Temp\input"))


                string newFile = "";

                using (var bitmap = (Bitmap)Image.FromFile(file))


                    bitmap.SetResolution(200, 200);

                    newFile = Path.Combine(@"C:\Temp\output", Path.GetFileName(file));

                    bitmap.Save(newFile, ImageFormat.Png);


                using (Image image = Image.FromFile(newFile))
