Re: How to generate WPF controls Dynamically

Why not take the data, load into class objects and binding the object to a form or the collection of objects to a ListBox. The ListBox would use a WPF DataTemplate to render the controls. Lots of examples here on Code Project for data binding and data templates.

This is very straightforward in WPF and should be fun to code.

WCF BasicHTTPBinding Thoughts

Hi All,

I'm just doing some reading on backwards compatibility for WCF services to enable them for use over the wire by ASP.NET and .NET2.0 clients.

I'm getting some conflicting info from blogs posts and wotnot (isn't that always the case?)

Obviously BasicHTTPBinding doesn't have the nice built in security contexts that you get with WSHTTPBinding but as I understand it as long as you configure the basic binding to use SSL Transport security (with certs) you should be fine using basicHTTPBinding. Considering that we need this backwards compatibility we don't really have any options other than BasicHTTPBinding ...

Has anyone got any real world use in this kind of setup? How did it go? Are there any gotchas to watch out for?

Cheers,

Jammer

Probably not relvant, but if you want to consume them from Silverlight, it only supports httpBasicBinding as well.

ExecutionEngineException when calling Application.Run

I'm trying to do a simple thing and WPF doesn't allow me to. I want to show a login form before running the main form. The login does run but the main form doesn't. It throws an ExecutionEngineException with message “Exception of type 'System.ExecutionEngineException' was thrown.” with no inner exception.
I hope someone tell me the right way to do it before I turn to a workaround. Thank you in advance.

public partial class App : Application
{
    protected override void OnStartup(StartupEventArgs e)
    {
        base.OnStartup(e);

        var login = new Login(); // a wpf window
        if (login.ShowDialog() == true)
        {
            var main = new MainForm(); // a wpf window
            Run(main); // exception here, .Show doesn't work, .ShowDialog doesn't work
        }
    }
}

It turned out to be a low memory issue since I was running a virtual machine on a 1 GB RAM D'Oh! | :doh:

. Sorry if I wasted your time.
.Show works so does .ShowDialog
.Run doesn't since it's not what it is intended to do.

Hi Everybody,
I have Silverlight application and WCF Service under one solution.In my application i'm bionding some data ( from sql server ) to DataGrid. If i run this application in my system result is coming properly i mean data was binding to datagrid correctly.

If i publish this website in my IIS by using new -> virtual directory. Error is coming like " Unhandled Error in Silverlight 2 Application An Exception occurred during the operation, making the result invalid ". For reference i'm giving my web.config file also here:

<system.servicemodel>
<behaviors>
<servicebehaviors>
<behavior name="TestProject.Web.TestSilverLightServiceBehavior">
<servicemetadata httpgetenabled="true" />
<servicedebug includeexceptiondetailinfaults="false" />
</behavior>
</servicebehaviors>
</behaviors>
<servicehostingenvironment aspnetcompatibilityenabled="true" />
<services>
<service behaviorconfiguration="TestProject.Web.TestSilverLightServiceBehavior" name="TestProject.Web.TestSilverLightService">
<endpoint address="http://localhost/TestSilverLightService.svc" binding="basicHttpBinding" contract="TestProject.Web.TestSilverLightService" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
</system.servicemodel>

endpoint address i tried in different ways also:

like

1. <endpoint address="" binding="basicHttpBinding" contract="TestProject.Web.TestSilverLightService" />

2. <endpoint address="http://localhost/TestSilverLightService.svc" binding="basicHttpBinding" contract="TestProject.Web.TestSilverLightService" />

3. <endpoint address="http://wm8bgfhos-062a(mySystemName)/ TestSilverLightService.svc" binding="basicHttpBinding" contract="TestProject.Web.TestSilverLightService" />

Please help me to solve this issue.

Thanks in advance from core of my heart

Publish the WCF service on your host, and then check you can access the metadata. (the .svc file)

WCF SSL For Newbies

Hi All,

I'm having horrendous problems getting a WCF service secured and available outside our network domain.

I've got little to no IIS experience to boot making this whole process really painful at the moment. Does anyone know of any good links on how to show a dummy what is actually required in order to make this work?

I feel your pain. It took me a long painful day to get mine up and running,
and I had never used IIS before (beyond hosting an FTP server) nor have I ever
done any web programming.

Anyway, here's a few links I bookmarked in the process, relevant to hosting/SSL. If
I bookmarked them, that means I got at least some useful info from them. Smile | :)

Configuring HTTP and HTTPS[^]
How to: Configure a Port with an SSL Certificate[^]
Tip/Trick: Enabling SSL on IIS 7.0 Using Self-Signed Certificates[^]
Hosting a WCF Service using IIS7 and Windows Vista[^]

In the end, IIS 7 really did all the work. The hardest thing for me was learning how to
use its configuration module (i.e. where to find the settings I needed).
Any web.config issues I had were pretty easy to track down in the MSDN WCF documentation.

Good luck man! Smile | :)

Thanks so much for this Mark, I'm going to work my way through the links you provided this morning.

I'm on IIS6 on Server2003 ... do you think it would be prudent to upgrade this to IIS7 before moving forward?

Well - IIS7 was introduced with Vista. You can't run it on Server 2003.

What is the best solution for User Interface of VC++ app?

Dear All,
I just want to redesign one of our unmanaged VC++ apps.
I have drilled WPF for several weeks,but no solution has been found.
Because I can not play video stream from our unmanaged VC++ apps in UI.(I want to use CCW for communication between the managed WPF UI and unmanaged VC++ apps)
I am a beginner in programe, and thirsty for a solution.
Any hint and suggestion will be appreciated!

I don't know what the best solution for you is, but in my opinion
WPF isn't the best solution if you stay with C++.
First, WPF is managed. Second, you'll get no designer support in
Visual Studio or Expression for C++.

If WPF's features and programming model suit your needs, I would use
C# for the UI, keep your existing native C++ in DLLs if necessary, and
use C++/CLI to bridge between the managed and native code.
In fact, that's what I did/do Smile | :)

I appreciated your answer deeply.
Our native C++ app is such a big system based on document/view framework of MFC,including 10 dlls at least,that UI is only one of those.Replacing the UI with a new one with friendly outlook and usage is my task.
I will research C++/CLI at right.
Any solution else, other than WPF?

I need to figure out how to customize cut&paste built in command on a context menu to do multiple functions. I need to highlight text from a text box then click on the context menu which shows up after right click, which needs to take me to a new form and automatically paste the text in another Text Box on the new form. I'm wondering if this is possible???
Any help would be appreciated..

Thank You!!

5-Jan-09 15:16

I have JSON string as a out put of some http://localhost:1586/Versentia.Web.UI/DataHandler.ashx
where requestAction = GetAll and requestType: ObjectInstances.
When I see the response using firebug, I can see the data returned by GetAll method,
But when I write follwing code, I don't get data;

var url = new Uri("http://localhost:1586/Versentia.Web.UI/DataHandler.ashx/");

WebRequest request = WebRequest.Create(url);
var response = (HttpWebResponse)request.GetResponse();
Stream dataStream = response.GetResponseStream();
var reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
var metaData =responseFromServer.Deserialize<dictionary><string,object>>();

I don't know how to access the GetAll method to retrieve the ObjectInstances object. I want to create WPF based on the retrived object. I am very new to programming and need to achieve this asap.
Please help.
