I'm using an object of FileSystemWatcher to monitor a shared folder on my computer. If a file was copied from a computer in the same net segment to the shared folder, the Created and Changed events of FileSystemWatcher were fired. But, strangerly, if a file was copied from a computer in the different net segment to my shared folder, only the Created event of FileSystemWatcher was fired. I didn't catch any exception in this case and the file was copied. I have tried differet file size, but only the Created is fired.
I need do something when the Changed is fired and I don't know whether the file copied to my shared folder is from the same net segment or not .

I set my object of FileSystemWatcher like this:
watcher.Filter="*.*";
watcher.NotifyFilter=NotifyFilters.FileName|NotifyFilters.LastWrite|NotifyFilters.Attributes;

So,can anybody tell me how to fire the Changed event in this case or why the Changed event can't be fired?
Thank you!!!

Configuration Config = ConfigurationManager.OpenExeConfiguration(strexePath)
ResXSection resXSection = config.GetSection("ResXSection") as ResXSection

the section is encrypted by ProtectedConfigurationProvider Class which comes form MS,
so i must use [ config.GetSection("ResXSection") ] to get the section info.
because it can decrypt the section automatically.

the parameter [strexePath] is the file's path,
and the file save XML info.
Now I have some info in my database.I get it from database,and then put it in a String strContent
not in a file.

I want to read it by Configuration method.

but
Configuration Config = ConfigurationManager.OpenExeConfiguration(strContent)
this method has no.
who can help me with it?

PS:
i can not add a new File in disk.
it is not allowed.

thank you

.NET Framework from Microsoft can only be used in Windows.
If you want to used .NET Framework in Linux, then
you must go to Mono Project.

It was designed to be platform independent, but Microsoft only provides a runtime for Windows. Look at Mono or Portable.NET for for alternative platforms.

Taskbar Band Object stealing focus

I have a textbox on a toolstrip that is being displayed on my windows taskbar as a band object (essentially http://www.codeproject.com/csharp/BandObjects20.asp).
I have installed a global keyboard hook, and can respond to key events.

Is it possible to globally shift the focus to my textbox in response to a key event? Can anyone point me to any information, preferably c# but any code is fine, regarding this?

Using FindForm() returns null, so I can't call Activate() on it, and calling Focus() on the band object does not do anything. Calling Focus() on my textbox does indeed change the focus within the band object, but my input is still sent to the active window.

Cheers,
Xavier

Hi guys,

I've got a pictureBox in my program and need to get the path of the image it holds. I know I can get the Image with myPictureBox.Image but I cannot get the address of this image. I tried to save the address string to this image's propertyItem[].Value but cannot convert from string to byte[]...

Is there any idea how I can get any Image's address(path) string ?

hi
put the path of the image after load in the tag property of the picturebox.
i.e. myPictureBox.Tag = "path of the image";

Have you looked into Microsoft's COM Interop? It's designed to allow two way interoperability between COM and .NET.

Read about the tlbimp[^] tool. It generates a wrapper around the COM object, that is callable from any .NET language.

Hi,
ASP.NET Datagrid has an event known as ItemDataBound event. Basically this event will get fired when each row is binding to the datagrid.
So for displaying the image button and label, you can itemtemplate of the datagrid and for databinding to these controls, you can use ItemDataBound event
The syntax of ItemDataBound event is given below
private void YourDataGridName_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
//Here you should get the dynamic data from Database/file system etc. and bind to the controls
}

Singleton object

Hi all,
we have a singleton class which has some functions used to do testing a harware.

Our main Exe will create an object for that singleton class(which opens Com1 port and communicate with hardware). so the Exe will do communication test with hardware it is working well. We are using one testing tool (teststand)(a COM EXE)to do various testing with hardware, Testing tool provided some class libraries to execute test profiles . Main exe will use these libraries to execute tests when the user clicks Testbutton. after that testing tool(teststand) try to create an object for that singleton but it returns new object not the existing one which is created by EXE. So it throwing me exeception "Com1 port access denied." (since we created object for signleton class @ very first in EXE)

My question is Since that testing tool runs in a separate Appdoamin will the singlton class create separate object for different appdomain? if so is there any solution to reslove this?
Hope i clearly explained my probs.
Thanks in advance
Srini

The library is loaded separately for each application, so you can't share a singleton between applications.

MemoryStream memoryStream = new MemoryStream(data);
Image img = Image.FromStream(memoryStream);
