Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

Opening or Navigating to a .aspx page from SilverLight application

Hi,

I am currently working on a SilverLight application that uses a WCF service to create and populate an Excel file and return the Result as the path on the server where the excel file is saved. This returned path will be used by the user to download/save the file.

I initially tried using the 'HypeLinkButton' and assigning the returned URL to the 'NavigateUri' property of the hyperlink. It did not work as when I clicked the URL, the page got navigated to a blank page and the error on the page was the following:

Error:
ManagedRuntimeError error #4004.
UnauthorisedAccessException Access is denied

Once I faced this issue as an alternative I tried navigating to a aspx page by opening a new window and specifying the window's URL as the returned file path. I couldnot find much on this online as well.

Any suggestions?

I do something like this to open a browser window when clicking on something. May not be exactly what you need, but perhaps can get you headed in right direction.

string redirectLink = "http://www.somedomain.com/some.xls"
string browserWindowOptions = "resizable=1|scrollbars=1|menubar=1|status=1|toolbar=1|titlebar=1|width=1000|height=725|left=5|top=5"

HtmlPage.Window.Navigate(new Uri(redirectLink), "_blank", browserWindowOptions)

Split WPF, WCF, and WF forums?

So...I've been looking for WF threads to see what kinds of questions ppl have been asking, and what the solutions were. I dug through like 10 pages or so of WPF questions and finally gave up. Could we split off the WF and WCF forums so that the questions don't get drowned in the deluge of WPF?

Thanks.

Hi,

deciding on new forums, and how to partition the topics, must be a challenge.
Initially a new forum risks remaining rather empty, after a couple of years a forum may be flooded
and deserving a split.

Anyhow, searching the all the forums for "WF" currently yields 35 hits; you ar familiar with the
"Search Messages" button, are you?

How many ways can you search for all the variations of WF? WF, WWF, Windows Workflow, Windows Workflow Foundation, Workflow Foundation, Workflow. Throw in more targeted questions like sequence, action, etc., and searching becomes a royal pain. Hence the request.

Accessing WPF Resources

I am working on a project which requires Globalization, and have run into something I'm really not sure how to address. Any thoughts would be appreciated.

For the sake of brevity, let's say my solution has two projects, a WPF application for the GUI and a standard class library for the DAL.

The WPF application has a ResourceDictionary containing all of the strings I will need to Localize. I would like this ResourceDictionary to contain the Strings used for displaying validation error messages to the user.

The DAL class library contains my Business Objects, which implement IDataErrorInfo to supply validation logic.

The question, then, is what is the best way to supply my localized strings (which exist in the WPF project) to my business objects (which exist in the standard class library)?

Thanks,

Keith

I have read the article you are referencing. It is using resx files for the WPF application's resources, not ResourceDictionaries. Therefore, it is not relevant to the problem domain of my OP.

Hi All,
We have to develope a desktop App. using WPF. Our application will be requesting a web service by posting requestAction and requestType .
The response from the web server is somewhat like this {

"TotalCount": 0,

"Data": [

{

"ObjectInstanceID": 1,

"LocationID": 3001,

"ObjectDefinitionID": 1,

"Name": "Boiler",

"Location": {

"LocationID": 3001,

"CompanyID": 3007,

}

}

],

"success": true,

"GeneralError": null,

"StackTrace": null,

"ItemID": 0,

"errors": [],

"stackTraces": [],

"IsLoggedIn": true

}
We would like to deserialize this response into a dictionary, but because of syntax "Data[", it thinks that it is an array.
I would like to generate wpf controls based on this out put. Does anyone know how to proceed?
Thanks in advance for your help,
Veena

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

Jammer7-Jan-09 23:38

7-Jan-09 23:38

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 | :)
