I've just started playing around with WPF. Is there is any way to run a Component control such as a HelpProvider on a WPF window? I've looked over the WindowsFormsHost and it only seems to support items that inherit from Control.
Google has only shown me examples of how people have re-written HelpProviders or Tooltips etc instead of using the old ones.

Hi,
does someone have experience with WPF applications using terminal server sessions like Terminal Server or Citrix?
We plan to redesign our product and have to decide if we will using Windows Forms or WPF. Most of our customers
using Terminal Server. We ask ourselves if its a good decision to use WPF. What about the memory capacity, CPU usage, if 100
clients using a WPF application on Terminal Server?
Does someone have experience with that combination?
Please only seriously meant answers.
Kind regards
Dirk Klimke

It can be done. Take a look at Project Apollo (Citrix Multimedia Virtualization Initiative) for more information. Basically, there used to be a problem with WPF on Citrix, but now graphics hardware is utilised in the same way as Citrix did for GDI+ (there was a problem where WPF required 16bit, but CPS only utilised 15 out of the 16 bits which has now been corrected). I hope that helps.

How to check whether point belongs to the Line object in WPF?

Hi All,
I really want to use this tool to debug and generally learn more about WPF but I just can't seem to get it built properly.
Everytime I launch it, the 'Chooser' dialog opens and contains all the right things (ie: running WPF apps) but selecting one and clicking on 'Snoop' does nothing.
I've tried just building the C# bit (it says on the website that the C++ bit doesn't need building) building it in Release (the compile fails) and Debug modes. I've tried building the whole thing again as well, it just never seems to work.
Anyone have any ideas?

how do i drag and drop a picture into richtextbox where i need to save that into the database sqlserver in wpf c# language?????.. also, how should i declare the the field in the datbase?
thanks

You need to hook the RichTextBox's Drop Event[^]. As far as the field in the database, if you are using sqlserver there is a datatype called 'image' that you can use. Here[^] is an example doing just that.

the first link that i provided was for the wpf richtextbox.
I guess i need more information. Why do you want to use a richtextbox for this? why not a listbox or listview?

To save the RichTextBox, you could do this:
myRichTextBox.SelectAll();
using (MemoryStream ms = new MemoryStream())
{
myRichTextBox.Selection.Save(ms, DataFormats.Xaml);
ms.Seek(0, SeekOrigin.Begin);
using (StreamReader sr = new StreamReader(ms))
{
string myXaml = sr.ReadToEnd();
SaveToDatabase(myXaml);
}
}

Hi All,
I'm a bit stuck on this and the Infragistics Documentation server has been down all weekend. Would it really hurt to had locally in PDF???
I'm doing this in a button click:
private void btnScanDirectory_Click(object sender, RoutedEventArgs e)
{
object SingleDirectoryResults = SampleSort.DataLayer.ScanSingleDirectoryForFiles.ScanDirectories(@"G:\samples\");
}
SingleDirectoryResults is a generic list that implements IEnumerable, how do I go about setting this new dynamic object as the data source for the datagrid?
|

Please have a look at this link on using the ObjectDataProvider in WPF.
http://www.beacosta.com/blog/?p=22[^]
You will bind your SingleDirectoryResults to the datagrid using the ObjectDataProvider.

My problem is very simple: I have one project in my solution. It contains WPF User Control and WPF Window (which displays this control). In User Control I have an Image control:
<Image Margin="56,22,44,128" Name="image1" Stretch="Fill" Source="/WpfApplication20;component/Niebieskie góry.jpg" />
In .cs file I got the following:
public UserControl1()<br />
{<br />
InitializeComponent();<br />
<br />
image1.Source = new BitmapImage(new Uri(@"Zachód slonca.jpg")); <br />
}
Both images are included into my project as a RESOURCE. Project builds with no errors. However, it throws exception at run time. In my view the reason is that it can`t find the image to replace the previous one.
Thank you very much for any help

Please change this line of code to this and give it a go.
image1.Source = new BitmapImage(new Uri(@"Zachód slonca.jpg", UriKind.Relative));
If you still get an exception, please post the exception.
Also, where in your solution are the images? From the above, I assume that they are in the root folder of the application and not in a subfolder, correct?

Our solution seems to work on simple Images. It does not, however, on 3D graphics.
I attempt to create a ImageBrush (for a material on 3D figure). I got image file "FieldExample.png" which is in the root directiory (the same as *.csproj). It is included into project. Build action is set to Resource. I tried the following code:
DiffuseMaterial material = new DiffuseMaterial();<br />
ImageBrush brush = new ImageBrush();<br />
brush.ImageSource = new BitmapImage(new Uri("FieldExample.png", UriKind.Relative));<br />
material.Brush = brush;
However, I`m getting run time XamlParseException. Besides, Watch set on brush.ImageSource.Height property says: System.IO.FileNotFoundException.
Please don`t hesitate to ask me for a draft solution with that problem if needed
Thank you very much for any help

I found it out :
bi3.UriSource = new Uri("smiley_stackpanel.PNG", UriKind.Relative);

Hey there,
Please check-out this post.. The Screenshot of Silverlight 2.0 (beta 1) Controls[^]
but don't tell me we are peaking at the new neighbor.. 
I think that there will be 29 controls available in Silverlight 2.0 (beta 1)..
but a lot of very common and useful controls such as combobox, treeview, tab control are missing in 2.0 beta release.
"content control" is pretty interesting..
I guess "WartermarkedTextbox" would be something like TextBoxWatermark from Ajax Toolkit…
but I don’t know about MultiScaleImage.. Any idea?

I got valuable comment in my blog.. someone commented about WartermarkedTextbox and MultiScaleImage ..

Hi. I'm new to this WPF thing, and I was making a simple app (images, buttons, textbox...) when I noticed that the images always are shown at low resolution. No matter what property I set in vs2008, nor what image I load, it still has a bad appearance. Just for testing, I have tried the same images in a form in vs2005 and there they looks ok. What am I missing?

can you post your code and images?

I've created a simple test.
http://img235.imageshack.us/img235/2772/testresolutionmv6.png[^]
The left window is a windows form app, background image set to some png; the right one is a wpf form with an image control pointing to the same png. No direct code manipulation, just using the properties window, and both compiled with vs2008 and framework 3.5. As you can see the wpf has lower colordepth and a bit of aliasing (maybe difficult to perceive in the image) while the windows form renders the image ok. So, what am I missing? I've read about create a custom renderer to bypass the "independant device" dpi, but I believe it's too complex for such a simple job as view an image.
