Unfortunately, that won't help.
Since i'm already on another thread when recieving the event, that's nothing I can control.
The problem is access to the controls on the main thread when an event is recieved.

Is is possible to host .NET 2.0 controls in WPF on .NET 3.0?

Yes. .NET 3/3.5 is a superset of the capabilities of 2, so you can host 2.0 controls in WPF.

Thanks for the reply.
Do you perhaps know how to do it ?

Ok, So I'm trying to programatically set the left margin on three controls, a textblock named "Clock", a StackPanel named "TasksIcos", and a button named "Options". This is the code I'm using:
<br />
TasksIcos.Margin = New Thickness(TasksIcos.Margin.Left + 32, TasksIcos.Margin.Top, TasksIcos.Margin.Right, TasksIcos.Margin.Bottom)<br />
Options.Margin = New Thickness(-MiniModePanel.Width + 43, Options.Margin.Top, Options.Margin.Right, Options.Margin.Bottom)<br />
Clock.Margin = New Thickness(Clock.Margin.Left + 43, 0, -7, 0)
The only one that moves any at all, is "Options". The other two do not move regardless of what the values are entered.
Can a WPF guru tell me what I'm doing wrong here?

I'm spitballing, but what is the value of TaskIcos.Margin when this code runs? Is it null? If so, that is your problem.
Step through your code and see what is actually getting created.

TasksIcos.Margin.Left = -192 at runtime and in blend.
|
|
|
|

Can you post the XAML that these controls are in? This will help me get context so I can create my own test application.
BTW: When does this above code run?
Can you please post the entire method that these assingments run in.

Actually, I figured out not 10 mins after my last post. It seemed to be something with the animation that plays right before any of the actual code is run. I re-did the animation after screwing it up doing something else, and everything seemed to start moving when it supposed to.
Thanks for your help though, and I apologize if I wasted your time.

Glad you got it all working!

I am binding the Customers to the ListView and contentControl.It works fine.Also i am binding SecurityData which says whether the Email is visible for an customer based on the companyID and LocationId.I have the securitydata in the Xml format.It is binding well for the first record when i navigate between records it is not reapplying the binding based on the filtered data.Please go through the code and give your suggestion why it is not working.

It seems from everything I've been told and seen so far that you can't access a sql server through anything, but WCF. Is that really true?
The application arcitect at work demonstrated a very simple app that used isolated storage and he said he couldn't tell it the location of the actual data storage. When he did it didn't put it in the path he specified.
Your thoughts.
|
|
|
|

You can access SQL Server through SOAP 1.1, i.e. a web service (whether it's a WCF Web Service or a good old fashioned WebMethod type).
This[^] should tell you where things are stored with Isolated Storage.
|
|
|
|
|
That's what my point is though. You have to hit a web service and cannot directly access the sql server with ADO.
Thanks for the link.

True - but when you think about it, that's a logical thing to want to do. Typically, your database will be behind a Firewall in a DMZ. This means that you really should have something in the way so that the DB doesn't have to be exposed to the outside world.
|

Most of the web apps here aren't exposed to the outside world. They are for internal use only.
I do see your point about the DMZ, though.

Hello,
I'm writing a windows application that uses the Amazon FPS web service. I would like to use WCF, though I don't have much experience with it yet. I thought that by adding a web reference to the service WSDL, that a proxy class would be created for me. The web reference was added, and I can browse the types defined in the WSDL in the object browser, but Visual Studio did not generate a proxy class.
What's the best way to proceed? Do I have to use svcutil to generate the proxy code?
Thanks!
Ian

You need to add a service reference.
Right click the project and [Add Service Reference]
Pop the service url into the address box and hit [Go]
Give it a name and click [OK]
...
|
|
|
|
|
Is this available in VS 2005? I couldn't find an options for adding a service reference. There were two options: Add Reference, and Add Web Reference.
Any ideas?
Thanks!
Ian

Once I installed the VS 2005 enhancements for .Net 3.0 (WPF,WCF) I had the "Add Service Reference" options.
Thanks for your help, Jammer, as it pointed me in the right direction.

No problem fella ... I've only ever worked with .NET 3.5 / VS2008 ... never had the joy of using the VS2005 extensions.
