Ok. Now it is not a cross post. A help will be more appreciated. 
I have also checked the problem with other developers in my offline network, but couldnt get the reason for the same. All of us are stumped as to why the executable doesnt execute the function. I shall just give a glimpse of the situation again.
A German language OS compiled code does not transfer the control to GenDefaultReport function in the BackgroundWorker thread, when the code is executed on the English language OS. The more detailed description is mentioned at the start of thread.

This is the question
Well I've never heard of that but I have never done any development using the different OS versions. Here are some obvious questions you likely have already investigated:
How do you know it's not called?
Have you stepped through the code in an environment where it doesn't work?
Is there a flow of control bypassing the call that might flow different due to the language? Like checking a Date or string or something not implemented with proper internationalization approachs?

->How do you know it's not called?
I had written some message boxes at the called function start and also was creating a log file for all the functions being called.
->Have you stepped through the code in an environment where it doesn't work?
Yes i have debugged the code in both the environments, but didnt get the reason.So am asking here in the forum.
->Is there a flow of control bypassing the call that might flow different due to the language? Like ->checking a Date or string or something not implemented with proper internationalization approachs?
There is no flow control statement.
Can you please ask your co-developers about the problem.I have also asked developers other than my company, and even they haven't heard of this behavior. The solution was to just re-compile the code in English OS.

In .NET 2.0 great strives have been made to make binary serialization more version tolerant, with new or removed fields no longer throwing exceptions. Although one scenario that keeps throwing an exception... when the type of a field has changed. Using OptionalFieldAttribute one can indicate to omit during deserialization a new field, if the data for that field is not present in the old stream.
Is there any declarative (such as TypeConverterAttribute) or imperative mechanism to handle situations when the type of the field has changed, to prevent exception from throwing when data type of one or more fields has changed? Essentially to ignore reading data for fields that have different type between definition in old serialized stream and new definition in assembly.
Thanks in advance

Not sure if such attribute exists. If one does not exist, you can write your own.
Or you can catch the exception during the Deserializing event which is raised before deserialization. You can use the attribute:
[OnSerializing]
void TypeHasChanged()
{
//Handle type change exception
}

Why does <code>DateTime.ToShortDateString()</code> not use the system short date format? Surely that is the format you would want if you don't wish to override the default formatting?

I am currently working on deploying a .NET component (Windows Form - UserControl) for use [embedded] in Internet Explorer.
The actual delivery system is this:
I have a deployment project that packages everything as an *.msi
This *.msi + an *.inf are packaged in a CAB file, which is referenced in the CODEBASE attribute of the object tag in the markup.
This part is great - it is deployed, installed, & works fine.
What I am dealing with now is the upgrade process.. From all of my research & trials, which can more or less be neatly summed up on this page.. http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1536629&SiteID=1[^]
Since mscoree.dll is what has to instantiate the object for IE to host it, when msiexec installs my component, everything is installed referencing the .NET2.0 version, 2.0.50727.1433. So, for IE to be able to hook into the code base & install it properly, I have to append the version information (to the codebase attribute) as 2.0.50728. This is obviously sub-optimal, and presents the need for a potentially ugly workaround.
Per some of the articles/posts I have read, I have fiddled with registry values in the following keys, but to no avail.
HKEY_CLASSES_ROOT\CLSID\{...}\InprocServer32
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Code Store Database\Distribution Units\{...}
If anyone has had to deal with a similar case, or has any ideas on what to try, I would definitely appreciate the help!
Thanks -

And if they can be, how? Can't any other less space-taking program/environment take its place? And why?

Because the framework contains the code that your application calls. Unless you write an application that makes zero calls into the framework. But even then it requires the CLR.
Wajeeha wrote: And if they can be, how?
There are third party tools that encorporate what is needed into your application, but they are very expensive.
Wajeeha wrote: Can't any other less space-taking program/environment take its place?
At the end of the day you have to consider what your priorities are. If you require a small footprint then you have to design to that consideration from the start.
If you have already gone down the road of building the .NET application then you are probably stuck with that descision.

Why what? I don't understand "why" in this context.

Microsoft Research have a compiler called Pheonix that can do a little bit of everything (eg compile all of the languages that MS support).
It has been discussed to make it able to compile to native too.
So it's not impossible that we will see a C# to native compiler from MS in the future..

Their are open-source 'wrappers' for the .NET framework that allow .NET applications (up to 2.0 as of right now) on other OSs such as linux, mac, and unix.
A few to mention:
Mono
Portable .NET
Read about them at: Wiki article on .NET Framework[^]

I am creating assembley named Comp1.Comp1 contains a public method.The Global Cache contains a sencond assembley named comp2.here I must ensure that the public method in only from comp2..which permission we have to take GacIdentity or Strongnameidentity...anybody know plz reply me..

If you'r requiement ment is to call only the function of Comp 2 then only add the reference of comp2 to your application. It is not a issue of assembly security.

Hey, gang. I believe I have a question that ought to be easy to answer and not be stupid this time. I've Googled around and dug around MSDN, but haven't found anything addressing this issue, and I'd sure appreciate a tip.
I've constructed a nifty little form that contains a DataGridView for displaying some information. It is formatted just the way I want it, and everything was great until I decided that the DGV and related controls would be more pleasing to the eye in a GroupBox. When I dropped them in, the DGV immediately took on the font size and color attributes from the GroupBox, so I changed them back manually to the previous settings
Everything looks great during design time, but during run time the DGV takes on the font attributes from the GroupBox again, and looks awful. I've never run across this with other controls, which listen to me when I change their properties, even when they're in a GroupBox with differing properties. Does anyone have some insight into what is happening behind the scenes? Is there a way to prevent this behavior?
Thanks very much for the help!

Hi,
Below is my class that has its Type converter implemented.
TypeDesciptor.GetConverter(typeof(MyPoint)) doesn't return the converter for MyPoint but returns System.ComponentModel.TypeConverter.
if I implement a ICustomTypeDescriptor for MyPoint, then it works fine.
Does anyone have idea why it is not working?
[TypeConverter(typeof(MyPointTypeConverter))]
public class MyPoint
{
public int x;
public int y;
public MyPoint(int x, int y)
{
this.x = x;
this.y = y;
}
}
/// <summary>
/// Class that implements TypeConverter for MyPoint type.
/// </summary>
public class MyPointTypeConverter : TypeConverter
{
// Overrides the CanConvertFrom method of TypeConverter.
public override bool CanConvertFrom(ITypeDescriptorContext context,
Type sourceType)
{
// some code
return base.CanConvertFrom(context, sourceType);
}
// Overrides the ConvertFrom method of TypeConverter.
public override object ConvertFrom(ITypeDescriptorContext context,
CultureInfo culture, object value)
{
// some code
return base.ConvertFrom(context, culture, value);
}
// Overrides the CanConvertFrom method of TypeConverter.
public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)
{
// some code
return base.CanConvertTo(context, destinationType);
}
public override object ConvertTo(ITypeDescriptorContext context,
CultureInfo culture, object value, Type destinationType)
{
// some code
return base.ConvertTo(context, culture, value, destinationType);
}
}
Thanks,
Sowjanya.

I just tested it:
class Program
{
static void Main(string[] args)
{
var tc = TypeDescriptor.GetConverter(typeof(MyPoint));
Console.WriteLine(tc.GetType());
Console.ReadLine();
}
}
Result:
MyPointTypeConverter

This seems to be a problem only on Vista with a certain set of pictues.
For instance, here is a picture...
http://tinyurl.com/55psg9[^]
Here is an excerpt of the code I am using to display the thumbnail (special code because height > width in the particular picture).
<br />
float _scale = (float)_orig.Width / (float)_orig.Height * __DesiredSize.Width;<br />
Image _image = _orig.GetThumbnailImage ((int)_scale, (int)__DesiredSize.Height, tnCallBack, IntPtr.Zero);<br />
<br />
Bitmap _backgroundImage = new Bitmap (__DesiredSize.Width, __DesiredSize.Height);<br />
Graphics _graphics = Graphics.FromImage (_backgroundImage);<br />
<br />
Rectangle _toPut = new Rectangle ((__DesiredSize.Width - _image.Width) / 2, 0, _image.Width, _image.Height);<br />
_graphics.DrawImage (_image, _toPut, new Rectangle (0, 0, _image.Width, _image.Height), GraphicsUnit.Pixel);<br />
Displaying the thumbnail in the a listview shows black bars on the side. Same thing happens with the landscape pics.
Any help would be greatly appreciated.
