To use WPF, we need to use Visual Studio.
Unfortunately, your question is not very clear to me beyond that.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Am using this code and the problem is that, CPU usage is 100% when the dialog pops up for the user to confirm access to the web came and/or microphone. This happens with all browsers, you just leave the silverlight popup to wait and you can see the plugin to crash after some time.
But this is not a problem that occures only in browser enviropment, even if i run the application out of the box, with the slllauncher.exe, the same problem occures. 100% cpu usage and the dialog waits there. In browsers the dialog crashes cause of the plugin manager sees 100% cpu and thinks the silverlight plugin has crashed. Am using SL 4 with Visual studio 10, same thing happens in IE,FF4,FF3.5,Chrome.
This causes problems in PC's with windowsXp and with slow single core cpus, cause gets 100% and even the dialog freezes.

Someone know what is this dll file "Log4Net.dll" ???
In my SL project , itt is located in the " \bin\log4net.dll " folder on the server. If i delete this file, it will recreate automatically.
And is giving errors during compile.

If it's not in your project's references, then you're probably using a third-party library that uses it.
Maybe you should try to diagnose the bug instead of cutting out dependencies.

i tried to remove the crystal report references in my web.config file and havn't had problems.(no error in compile time and file isn't recreating after deleting it).
So it mean Crystal Report is using this Log4Net ???
I installed "SAP Crisal Report, version for Windows".

Maybe... I don't know. But something you're referencing must be pulling in log4net, or it wouldn't be copying over.
Again, though... log4net generally works very well... Maybe you should try to track down the error instead of trying to wipe out the entire library.

Have you ever used Crystal Report in your Silverlight project.??

No, I use log4net in a C# windows service.

Go to the site I linked, and see for yourself... It's for writing log files.

Thanks Ian to help

No. Something else might be though.

How have you obtained this Dll?
Silverlight may not support this version of the Dll.

In a textbox of my wpf application, I would like to only allow numbers i.e.:
21 or 19.50 or 12.75 or 10
Can you see how my code below can be corrected because it only allows numbers such as 21, 1950, 1275, 10, etc... ?
Thank you
private bool IsDecimal(string text)
{
bool blnValidDecimal = false;
foreach (char c in text)
{
if (Char.IsNumber(c))
{
blnValidDecimal = true;
}
if (char.IsDigit(c))
{
blnValidDecimal = true;
}
}
return blnValidDecimal;
}
private void txtAvgGrade_PreviewTextInput(object sender, TextCompositionEventArgs e)
{
e.Handled = !IsDecimal(e.Text);
}

You might find decimal.TryParse useful.
decimal d;
return decimal.TryParse(text, out d);
|
|
|

Rather than attempting to reinvent the wheel, why not make use of the Attached Behavior I wrote here[^]? It gives you a lot of flexibility in how you accept your numbers, and manages features such as disallowing/allowing negative numbers, the number of decimal places allowed, whether or not the textbox accepts decimals or not.

thanks but I would like to get this existing code working.
Any thoughts on that please?
Thanks

Take a look at how I validate the input in that code. That's what you need to do. With your code, you are missing things like coping with the user pasting crap in. As long as they don't press a key, you have left your validation wide open.

Bloody net nazi won't let me in there, just you wait till I get home to a decent connection I'm gonna vacuum up all those behaviours I can find. I am only just getting a handle on how useful these things are.
I have a tremendous dislike for rewriting code and these fit very nicely with that idea.

They really are useful. I love behaviors; so much so that we are supplying a lot of them to clients to cut down on the amount of boilerplate validation that needs to be performed.

In a textbox for the wpf application, how can I make sure the user enters a valid email address please?
I am using regular expressoion as follows but clicking away from the textbox still seems to be ok even if there is no proper email address in the textbox.
And I am not sure if regular expression is the right thing for this purpose.
Thanks
My existing code:
private static bool IsEmailAllowed(string text)
{
Regex regEMail = new Regex(@"^[a-zA-Z][\w\.-]{2,28}[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$");
return !regEMail.IsMatch(text);
}
private void txtEmail_PreviewTextInput(object sender, TextCompositionEventArgs e)
{
e.Handled = !IsEmailAllowed(e.Text);
}
This is what I used to do in windows but there is nothing similar to it in wpf
private void txtEmail_Validating(object sender, CancelEventArgs e)
{
System.Text.RegularExpressions.Regex rEMail = new System.Text.RegularExpressions.Regex(@"^[a-zA-Z][\w\.-]{2,28}[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$");
if (txtEmail.Text.Length > 0)
{
if (!rEMail.IsMatch(txtEmail.Text))
{
MessageBox.Show("E-Mail expected", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
txtEmail.SelectAll();
e.Cancel = true;
}
}
}
