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?

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.

Great example and again good question.
I copied your image into a project and got the same results.
The form on the left is a different size and shape than the one on the right. So WPF is doing its best when it resizes the image to render it.
You can try creating a VECTOR image instead of a BITMAP image. These scale perfectly in WPF.
Yor can create this in either Expression Blend or Expression Design.
I'm going to MIX08 next week, I'll add this question to my TODO list and get back to you next Sunday when I get back.

Thanks. Just note that the source png is bigger than the two windows (it is, in fact, a background image of a program that run fullscreen, 800x600 IIRC) so both programs has to scale it.
I'll try with a vector image and maybe building the same project in Expression, and I'll post here the results.
Cheers.

On option:
If the image is larger than the application, then don't scale it. Just let more of the image be exposed as the application is resized.

Same results with Expression Blend, both scaling and maintaining original size, using an Image container or using a brush created from the image:

Just seems that framework 3.5 doesn't decode the image properly (or I can't find the place to set it up). I'm downloading expresion desing to try a vector image.
