I'm using the 3.5 sp1 beta, this is supposed to have better error messages and that seems to be the case:
Part URI cannot start with two forward slashes. Error at object 'PortfolioDataSource' in markup file 'WoodgroveFinanceHost;component/stockhost.xaml' Line 287 Position 74.
If you change it to pack://application:,,,/FinanceExplorer/Equity.xml it should work.

Thank you very much, buddy.
I have checked the path in StockHost.xaml. I found the following code that seems correct.
<xmldataprovider x:key="PortfolioDataSource" d:isdatasource="True" source="pack://application:,,,//FinanceExplorer//Equity.xml">
I'm not sure whether you have VS 2008 or not. If you have, please try the following steps..
1) Download the application.
2) Extract it
3) Open it in VS 2008.
4) Go to Solution Explorer.
5) Double-click to open Page1.xaml. (You will get 2 errors at designtime)
6) Double-click StockHost.xaml.(You will get 11 errors at designtime)
If you close those files (e.g Page1.xaml or StockHost.xaml), those errors will be disappeared. Any idea why it's happening like that?
And, Like I said above, the path seems correct... Can you tell me how to change?

You need to change pack://application:,,,//FinanceExplorer//Equity.xml to pack://application:,,,/FinanceExplorer/Equity.xml
Notice the double slashes in the original.
I didn't get any errors, however the .NET 3.5 SP1 Beta did cause problems for the VS designer.
That single change in StockHost.xaml did allow me to compile and run the sample, it didn't work beforehand.

Hi All,
I'm using XP SP2, MSVS2008, Firefox verison 2.0 and IE6.
I created a C# WPFBrowserApplication and placed an image control in it with source given as "E:\WPF\WPFBrowserApplication2\images\imag.jpg".
When I run the application I'm getting exception :
XAMLParserException was unhandled: Cannot create instance of 'Page1' defined in assembly 'WpfBrowserApplication2, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. Exception has been thrown by the target of an invocation. Error in markup file 'Page1.xaml'.
The same exception occurs if do the code behind for image as below:
BitmapImage bmp = new BitmapImage();
bmp.BeginInit();
bmp.UriSource = new Uri("file://E:/WPF/WPFBrowserApplication2/images/img.jpg");
bmp.DecodePixelWidth = 200;
bmp.EndInit();
Image img = new Image();
img.Width = 200;
img.Source = bmp;
I'm getting the exception when bmp.EndInit() is executed.
In windows application, the image is loaded if image control is used.Otherwise there is no exception, but image is not loaded.
(I've written the code in function Page_Loaded/Window_Loaded)
How do I load image in WPFBrowserApplication and WPFApplication without using image control?
Thanks & Regards,
Sanju.

Hi Kishore,
For this First u should have some html elements like hidden control in ur application.
After that In SilverLight Application use this code to set value to the hidden control.
pls add Windows.browser Assembly also.
HtmlElement.Document.GetElementById("Id").SetAttribute("value","nithya");

He can directly access the textbox by using HtmlElement.Document.GetElementById("Id"). No need to use Hidden Field.

We have a WPF app with about 400 users. One user, who has a high end machine ( 2 gig of RAM, good video card, etc ), reports that if he starts the app on boot, closes it and restarts it, it blows up. That is to say, at any point if he runs it a second time, it fails, even if he does it all right away. Here is the stack trace:
Not enough quota is available to process this command
at MS.Win32.UnsafeNativeMethods.PostMessage(HandleRef hwnd, Int32 msg, IntPtr wparam, IntPtr lparam)
at System.Windows.Interop.HwndTarget.UpdateWindowSettings(Boolean enableRenderTarget, List`1 channelList)
at System.Windows.Interop.HwndTarget.UpdateWindowPos(IntPtr lParam)
at System.Windows.Interop.HwndTarget.HandleMessage(Int32 msg, IntPtr wparam, IntPtr lparam)
at System.Windows.Interop.HwndSource.HwndTargetFilterMessage(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled)
at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled)
at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o)
at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter)
at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler)
We have our own logging in the app, I know for sure that the constructor for te MainWindow is completed, or in this code:
bool current = OvsUtility.GetInterfaceAnimalPanel().DualOverlaysOn;
singleOverlay.IsChecked = !current;
dualOverlay.IsChecked = current;
singleOverLay and dualOverlay are menu items, GetInterfaceAnimalPanel just returns an inner control from a user control.
We have no logging after this code, but we have logging the moment the Load event fires on the Main Window, and this code is not running, so the exception occurs in the above code, OR between the constructor and the Load event.
The only code that runs between these two, is a couple of window size changed events.
I assume it's something to do with his machine, as no-one else has the issue, but it's not low specced, so that's not it. Where do I look next ?

I know it's been quite a while, but I'm having a similar issue except mine occurs on any windows 7 machine (works fine on XP, Vista, Server 2008, etc and was working on Win 7 for a while), not sure of the cause...did you ever come up with a solution?

Create a new WPF Application solution and paste the code into it.
Run the application in debug mode.
Edit the grid.
Press the button.
Look in the Visual Studio output window and you'll see your new edited data.
I'm using a class instead of a data row, but the concepts are still the same.
You can look at the data context in the button's click event and see how to find the data.
In you case, Me.ListColor.Items will be a collection of DataRows. Just access the cells in the DataRow

Hello Karl, if your info is up-to-date, and your employer is empgovpower you might be the best person to answer my q's...
Our company, creates software for law enforcement agencies... one of our major clients, has a deployment where its web based with ASP.... and an oracle back... .. .. you can imagine the nightmare...
our system pretty much gets rid of the "paper" based processes and docs and makes them electronic.
so the review-approve process exists,... a lot of the fancy stuff you can do with applications., doesnt apply to law enforcement agencies as the purpose is pretty specific., however., UI exp can be ofcourse improved.. which is why i have this question for you...
you are actively moving old apps into WPF., i WAS going to redesign the asp web app into a Web service + winforms app., since most local/state agencies have a disconnect with their IT., its easier to give the client an updated thinapp/winform, than have it deployed to the web farms.. i do plan on eventually creating a web based portal... but for now., i have a couple of weeks in which i need to create an application that displays the data that has been colllected + entered., request changes., approve changes., supplement reports., and so on.... as you can see., the greater concern is making sure data is good., and things are entered correctly since many of the documetns are legal documents...
So the main issue is i have no time., ive been with .net since its alpha stages., and i know my stuff., i dont know if i have time to play with wpf and make mistakes...
what do you think i should do?
Wpf now? or winform now, WPF later....

If you design the architecture correctly then neither should matter, you can use what you're most familiar with at the moment to get the first edition out of the door. Once you've got somre spare time and read up on WPF then you can move the code-base across to WPF as opposed to Windows Forms.
The problem with WPF that I see is that if you're a programmer then in all likely hood you'll want to employ a designer and/or get some professional components to make your life easier and look better.
For a good example of what I meant in the above paragraph take a look at Josh Smith's Podder application where he gives an example of a UI designed by a programmer and a UI designed by, well, a designer. Do you think you're capable of the second option?
I doubt it. If it isn't intuitive then we need to fix it. - Chris Maunder

thanks for your quick reply
1996 - 1999 and creeping into 2001 i was a graphic / flash person... then i jumped into the programming world., i am a jack of all trades., i can do both., and have been... the main meat of my product is a .net CF app that collects data., ditching the boring winform look, i used opennetcf to create a pretty application...
while wpf looks really good, and it might make it easier for me to close the deal on the product when shown., i might have to go with winforms so that the product is complete...
p.s. thank you for the ref to podder
