If a AJAX-Enabled WCF should return an Object with a Date Property which is Nothing a Request to this Service fails.[code]Chrome displays on this call the following error message: "failed to load resource".Has anyone an explanation/idea for this behaviour and how are you supposed to prevent this problem?
View 1 RepliesI'm trying to do MVP where I have a view specific model that the presenter manipulates and the view binds to. There is no other connection between the presenter and view (the view fires off commands to the domain model via a gateway type pattern).
As you can guess, this makes the ability to bind to any property of any object really important.
I'm having trouble finding the correct way to bind to the Enabled property of a ToolStripMenuItem. Most controls have a .DataBindings property, but this one seems to lack it. I haven't found much info online about how to do this. Is it even possible?
I have a situation with several TextBox controls on a WinForm. "Rules" are processed on the Leave event of one TextBox (TextBox1) which can disable or enable the very next textbox in the tab sequence. It appears that if the "rule" disables the next textbox, focus remains on the prior textbox. In this case, the focus is in the wrong place AND, if user clicks "{TAB}" again, no events fire for TextBox1. I am looking for a solution that does NOT require hard-coded knowledge of the tab sequence to make tab navigation (and events) work properly. See small code sample below that demonstrates the problem:
private void textBox1_Leave(object sender, EventArgs e)
{
if (textBox1.Text == "bob") // simulating a "rule"
[code].....
The problem was first identified because of rules triggered in a class entity that was "bound" to the form controls, but data binding does not seem important to the symptoms.Is this a quirk/limitation of the WinForm event model?Rhino907

I have a usercontrol with a picturebox and a few buttons related to it, such as LoadFromFile, Paste and Zoom (that last one pops up a new form). Is there a way to override the basic Enabled property of the usercontrol so that I can keep the Zoom button active all the time, while turning off the other buttons?
I realize there are 2 "obvious" replies. don't do Enabled=False, create a custom method. do everything in the one form, not a usercontrol, so you can pick and choose disabling. Both are less than ideal, given that I'm putting this control into a couple of existing forms, so I'd like to work around how those forms already behave. So is there a way to override the behavior of my usercontrol when it gets disabled? What would be my best strategy?
I can load a generic user control just fine in my WCF service doing the following:
UserControl userControl= (UserControl) new Page().LoadControl("~/UserControls/MyControl.ascx");
However i can't seem to find any way to do this

I am getting the following error:Unable to cast COM object of type 'TESTSERVERLib.TestClass' to interface type 'TESTSERVERLib.ITest'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{DAFB7D76-0158-452F-8FD0-FF97A683DEA3}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).Object reference not set to an instance of an object.Whereas the same code works from an VB .Net Forms application.Can anyone explain why this code does'nt work in a VB .NET windows service.
Here's a problem: I've made an ActiveX control with VB.net (VS 2005) to use in a web application. The control has some properties and methods. The control loads fine in IE, calling methods works, but asking for a property with javascript is a problem.
[Code]...
The first time objTest.SomeProp returns 'Test' as it should. The second time is gives an error: 'Object doesn't support this property or method. After that, all methods and properties are 'unsupported'. Somehow this problem started after I implemented IObjectSafety interface in the control, but I have no idea how it affects the property and how to solve this problem.

When I try to compile my VB.NET web project, I get an error that reads:[PropertyName] is not a member of '[Namespace.Class]'The class referenced is part of a dll that the project references. The property definitely exists in the referenced class, and its access modifier is Public. What's more, if I update the reference, or just remove it and add it back, the error goes away: the intellisense shows my property -- all is fine.. that is until I try to compile again. Then the error returns. I've even restarted Visual Studio to no avail. What is going on?[UPDATE]After Will's comment, I've changed the namespace to something I am absolutely sure is unique. Now, I am getting more compiler errors of the same genre. The compiler is not recognizing some of the overloads although they are right there in intellisense. Weird!

When setting a DataSet row column to Nothing, like row.Date = Nothing, why does it initialize it to the data type minvalue? In this case a date, that gets set to 0000-01-01. The column is set to allow null etc., and if I don't set the row to anything at all, it will leave the column empty. So why does Nothing act this way?
In C# I would've set it to DbNull, I guess, but I'm a tad green on VB.NET - as you might be able to tell. :)
