Check whether you refreshed your service reference on the client side.
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.

yes, I have already and still do not see the new method inside the wcf.
As an extra test, I used the wcf client test and give it the endpoint. It shows the new method but still can not figure out why after refreshing the service references, the client does not see the new method.
Note that I see the old methods I created but anything new I add, does not get shown to the client in th esilverlight project.
Thanks

Well I would suggest just delete all your service references, client config file, bin and obj folder and then add them again.

Is the Silverlight runtime installed on your machine?
The browser should install it automatically.
Check this[^] out as well.

Hello all,
I am learning WPF now. I have a window which will launch a popup on click of a button. The popup contains a user control. I need to pass some parameters like first name,last name to the user control. I am from an asp.net background so my thought is like to pass these parameters as query string and assign it to the text box in popup. Any way, it is not possible in windows and I am sure there are better methods.
I am thinking about declaring a public get-set property in the popup for each parameters(I don't think I need dependency property). Then I will assign the values from the window.
Is it a good way of doing it?
Thanks in advance,
afsal

If your pop-up's job is to display first name and last name then I would guess that you probably have (for example) a Customer object, with properties of FirstName and LastName (for example)
your usercontrol could bind to such an object
your popup then would need an instance of that object to set as the datasource - so either have a public property
public Customer CurrentCustomer
{
set
{
}
}
or have a constructor which takes a Customer as a parameter, and performs the binding.
Using the property at least gives you the potential option of changing the Customer without closing and re-opening the pop up.

Please. Buy some books. We can't handhold you through the entire process of deployment. There comes a time when you have to read up on this yourself. The last two pages read like one long homage to your woes deploying this application with you creating a new thread everytime you come up against something.

hello I'm looking for a Flowchart control in WPF, I don't think there's an Open Source alternative in this regards (Also checked Visfire), and seems like prominent/best seller which come up first in Google is Mind Fusion
I missed anything? And better suggestion?

You posted this only a few hours earlier. You have been a member long enough to know that behaviour like this is unacceptable in the forums. Now, pack it in.

I am developing a 4.0 WPF application. It works great under Windows 7, but it behaves strangely under XP:
In XP, when the app opens new windows, these windows are devoid of content in their client areas until I move them with the mouse. As soon as I manually activate the window with the mouse, then the client area gets painted. However this quirk does not show itself in Windows 7.
Could this be a bug in the XP implementation of WPF?
The difficult we do right away...

Not in XP itself. In your video drivers.
Remember, WPF handles all the drawing for you via software and hardware acceleration. Make sure you have the latest and correct video drivers installed. Also, in your Advanced Display Settings (can't give you the exact way to get to those because I am on Win7), but its in the Display Settings somewhere. I think there is an advanced button on one of the pages. Anyways, its that page with the big slider control on it that lets you slide to the left to disable levels of driver acceleration. This often fixes rendering issues like these, but also makes things slower.
Theres not much you can do about it other then update your video drivers and/or get a new video card with less buggy video drivers.
Not having buggy video drivers is *CRITICAL* with WPF.

Wow, thanks Mr. Sledgehammer. I hadn't thought of that. I'll see about updating the drivers and making adjustments.
I have to demo the app for the boss, and I don't want it doing that during the demo!

On the windows server 2003, I am trying to deploy a silverlight 4 / .net 4 application.
I get the error page not found when trying to browse to the page.
Are there any settings or installs I need to do on the windows server 2003 machine?
Thanks

We already know. Stop reposting.

This is now solved as I had to set the web service extensions to allowed for asp.net 4
Thank you

I'm missing something in my understanding of how to use DP validation and probably in custom control design in general.
Here's the problem:
I've created a numeric text box, yeah another one. One feature it supports is a flag for whole number vs real number support. Another feature is Increment, where an Increment is 1 for whole numbers and 0 to 1 for real numbers.
I have implemented Validation Callbacks as:
var propertyMetadata = new FrameworkPropertyMetadata(1.0, OnIncrementChanged, OnCoerceIncrementProperty);
IncrementProperty = DependencyProperty.Register("Increment",
typeof (Double),
typeof (NumericTextBox),
propertyMetadata,
IsIncrementValid);
public static readonly DependencyProperty IncrementProperty;
[EditorBrowsable]
public Double Increment
{
get { return (Double) GetValue(IncrementProperty); }
set { SetValue(IncrementProperty, value); }
}
private static object OnCoerceIncrementProperty(DependencyObject sender, object data)
{
var value = (Double) data;
var numericTextBox = (NumericTextBox) sender;
if (numericTextBox.IsWholeNumberOnly)
{
return 1.0;
}
if (value > 0 && value <= 1)
{
return value;
}
return 1.0;
}
private static void OnIncrementChanged(DependencyObject obj, DependencyPropertyChangedEventArgs eventArgs){}
private static bool IsIncrementValid(object value)
{
var val = (Double) value;
return val > 0 && val <= 1;
}
My logic actually works fine, the problem is that it does not play nice with wpf. For example, in the properties window, if I set the flag for whole number and I enter .5 for the Increment the property window updates as expected, back to one (silently, without an indication I entered a bogus value). However, the XAML still shows the .5. Aside from that the logic of the control works correctly, it ignores the .5. If I type in the XAML editor I get no warning that the value is bogus. I believe this behavior is due to the logic in the coerce callback.
If I set a value in the properties window or in XAML that fails the logic of the IsIncrementValid callback, such as 2, I get a warning from both the properties window and the XAML editor and the value is never set.
Apparently the coerce validation callback is working for the properties window but not the XAML. The IsIncrementValid callback is working in the XAML and in the properties window. Of course the IsIncrementValid callback applies to the type not an instance. So the behavior I need is for IsIncrementValid to apply to instances so I can base the evaluation of validity on another instance property. In fact what I need is to be able to apply the code in the coerce callback to the isValid callback.
Any suggestions that would shed light on how to do this correctly would be appreciated.
I would also appreciate any suggestions for eliminating the plumbing code for DP's. Other then the callbacks, DP's are very much boilerplate.
Thanks in advance.

Hi,
I need to add custom deserialization to my Silverlight 4 application, but I'm having a VERY hard time, any help will be appreciated (please send codes ). I have tried to implement IClientMessageFormatter at nausea, but no luck...
I've also noticed a search on CP for IClientMessageFormatter gives no results, which makes me think I'm on a wrong track...
Can anyone please point me at a nice sample SL (4) app that does this, or a good article that shows the implementation (e.g. the MSDN article tells you all about IClientMessageFormatter except give you a nice example on how/where to implement it your app, and I don't mean implement it in your class )

All you neeed to do is create a shape object, either in XAML or in code, and then use that shape wherever applicable. Here's a link that discusses shapes and drawing:

this is the structure I have:
The development is done on my machine as follows:
using VS2010, silverlight 4
1- Silverlight application is created as a project
2- silverlight app has service references to the wcf project
3- web project is a simple project which has the clientbin folder and a default.aspx page
When running the .sln on my machine, all works fine.
I have copied the entire folders for both my wcf and web projects from my local machine into the c:\inetpub\wwwroot of the webserver (Windows server 2003).
on the web server, created two virtual directories. One for the web and one for the wcf project. each points to the appropriate folder under c:\inetpub\wwwroot
I made sure the endpoints in the file Servicereferences.ClientConfig under the wcf project in the webserver is pointing to the webservername:80
The webserver does have the correct mime file type i.e. .xap
I have also added the domain policy files onto webserver machine's C:/inetpub/wwwwroot/
In IIS, under the web project virtual directory, when I right click, browse, then it says "Page can not be found"
What have I done wrong please?
Thanks

When you run the solution is it the default.aspx page that is displayed?
|
|
|
|
|
yes.
Could this be to do with settings on the windows server 2003 machine that I am trying to deploy to?
