If it works in a unit test, there's no reason it shouldn't work in WPF. I wouldn't use this API though, if I were you, because it's designed to provided compatibility with 16 bit applications. You should look to use either the registry or a config file for your settings.

Agree with you, but it true, it happened.

I intend to write my classes to read\write ini file. I prefer to ini files than xml file as config file.
Glad to discuss with you and best wishes.

Without seeing your project, there's not a lot I can suggest.

I've just uploaded the latest version of MoXAML PowerToys, complete with the Scrubber utility from Kaxaml - Robby said he wanted a version of Scrubber that worked in VS and I was glad to be able to help. You can get this here[^]:.
This version of Scrubber allows you to update all of the XAML in a project from a single menu option.

Hi everyone ,
haven't read much about WPF , just some basic stuff .
Is it possible to simulate first person movement in a WPF application ? can i dinamically move the view point or something like that to simulate this ? Like first person shooters , but without the shooting part . Just simulate the walk around a room ..
Thank you !

You can - WPF goes way beyond what you can do in WinForms and does allow you to work in a 3D environment. I'm not sure that you wouldn't be better off using Managed DirectX though.

Thank you so much ! I'll start digging in

Hello Dudes =)
I want Bind a ComboBox to 2 DataSets/DataTables. One with a Countries list other with myUser data (this always with just 1 line)
the combo list the countries ok, but i dont find the way to bind de SelectedValue to de myUser data...
If I chage it to:
SelectedValue="{Binding ElementName=stData, Path=DataContext.OriginCountryIDColumn, Mode=TwoWay}"/>
The Binding find something to work with, but give me "A TwoWay or OneWayToSource binding cannot work on the read-only property 'OriginCoutryIDColumn' of type 'dtDAL.dsData+UsersDataTable'."
I take the "Mode=TwoWay" out and error persist
I change to "Mode=OneWay" and the SelectedValue don't get the value from the datatable
Can someone turn the light on please?

Help wanted clipping an image region and saving as new image....
Can someone please help me.
What I what to do is display a picture (image) and drawer a clip region using the mouse on a selected area on the image, this could be a retangle, square or a freehand shape.
I can display the image and clipped region using WPF as below. But what I cannot work out is how to save the clipped region of the image as a new bitmap image. The same problem if I create a image using pathgeometry, I cannot work out how to save the cropped part of the image.
If there is an alternative method instead of using WPF, please advice me.
c# or vb I don't mind, I just need a solution.
Thanks
// Sample 4
// Create the image to clip.
Image myImage = new Image();
Uri imageUri =
new Uri(@"C:\\Documents and Settings\\All Users\\Documents\My Pictures\\Sample Pictures\\Water lilies.jpg", UriKind.Relative);
myImage.Source = new BitmapImage(imageUri);
myImage.Width = 200;
myImage.Height = 150;
myImage.HorizontalAlignment = HorizontalAlignment.Left;
// Use an EllipseGeometry to define the clip region.
EllipseGeometry myEllipseGeometry2 = new EllipseGeometry();
myEllipseGeometry2.Center = new Point(100, 75);
myEllipseGeometry2.RadiusX = 100;
myEllipseGeometry2.RadiusY = 75;
myImage.Clip = myEllipseGeometry2;

I'm trying out Infragistic's WPF controls, and I got this problem:
I'm using XamDataGrid, and I set its DataSource to a DataTable.DefaultView.
The problem starts when I try to add/update/delete any of the rows. I don't expect it do it magically by itself, but I can't seem to find a reasonable mechanism for accomplishing this task.
Any idea what am I missing?

Oh... some one else is annoyed with the same thing, too?

Hi,
I want to create a wpf GroupBox dynamically . I want to apply specific font and forecolor to the header . Can someone please help me
to do all this in code behind.
Thanks,
Veena

GroupBox gb = new GroupBox();
gb.Header = "GroupBox!";
gb.Foreground = new SolidColorBrush(Colors.Red);
gb.FontSize = 20;
gb.FontWeight = FontWeights.UltraBold;
gb.Content = ...
...
You can also set a groupbox's header to anything you want.
For example, you could set the header as a TextBlock:
GroupBox gb = new GroupBox();
TextBlock tb = new TextBlock();
tb.Text = "My Group";
tb.Foreground = new SolidColorBrush(Colors.Red);
tb.FontSize = 20;
tb.FontWeight = FontWeights.UltraBold;
gb.Header = tb;
gb.Content = ...;
...

Hello,
I have a problem with Binding and a ListView.
I have an order system with Orders and Customers.
I tried to make a sort of Datagrid of the order system with TextBoxes so I can edit all the values.
These bind perfectly.
However, I also want a ComboBox in it, with a drop down of all the customers I have.
The XAML code pasted below here has two parts. One with 3 textfields and this ComboBox I speak of, and 1 containing the DataGrid.
<Window x:Class="WpfLookup.Window1"

</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
</Grid>
</Window>
If we focus on the first ComboBox:
<ComboBox
SelectedValuePath="customerID"
SelectedValue="{Binding Path=customerID}"
Height="23" Name="cbCustomer" Width="Auto" Margin="3" SelectionChanged="cbCustomer_SelectionChanged">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Source="Images/salome.gif" Height="Auto" Width="Auto" MaxHeight="40" MaxWidth="40"/>
<TextBlock Name="tbLastName" VerticalAlignment="Center" Text="{Binding Path=lastName}" />
<TextBlock Name="tbComma" VerticalAlignment="Center" Text=", " />
<TextBlock Name="tbFirstName" VerticalAlignment="Center" Text="{Binding Path=firstName}" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ComboBox>
This one works perfectly. But only when I change the ItemsSource in C# code:
this.cbCustomer.ItemsSource = dsCustomer.Customer;
It won't work when I would do it in XAML code:
this.cbCustomer.ItemsSource = dsCustomer.Customer;
Am I doing something wron in the XAML code?
I'm quite new to WPF.
The reason I ask this, is that this ComboBox will return in the datagrid, I can't however name it, because multiple ComboBoxes will be generated, and I don't have the name to use in C# code.
I hope my problem is clear and someone knows what I am doing wrong, thanks in advance for the help.

From the XAML perspective, DataContext for the ComboBox is limited by the ListView's(it's Parent) DataContext. In other words, since ComboBox is the child of ListView it can access DataContext of the ListView and bind itself to that or anything relative to that. You need to set the ItemSource of the ComboBox relative to what is set for the ListView.
What is ListView's DataContext ? Is it collection of Customer's ?
|
|
|
|
|
I have not set the ListView's DataContext in XAML, but I did this:
this.view = (CollectionView) CollectionViewSource.GetDefaultView(dsOrder.Order);
So it is a collection of Orders.
What I want to display in the ComboBoxes however, are Customers linked (through a foreign key, customerID) in the database). I have the CustomerID of the current row in the listview, but it needs to look a customer up. I managed to do this earlier when I did not yet use a listview. I managed this by using the following code:
this.cbCustomer.ItemsSource = dsCustomer.Customer;
So the combobox gets a different ItemsSource then the rest of the User Interface.
My problem is now, since the TextBoxes get generated in the ListView (depending on the number of orders in the dataset), I am unable to call them by their name in C# code to set the ItemsSource. How do I change just the ComboBoxes, whom have no names, to have the Customer as datasource?
I hope this clarifies the problem.
Edit: To be clear, the other fields work in the Datagrid, Textboxes show the correct values (for this example dates).

Check this MSDN[^]. Look for the section "Binding Related DataTables"
You can bind your ListView to the DataRelation between the two tables and can then access data from both the tables in the ListView.
|
|
|
|

That sounds great, but I have never heard of this DataRelation. I will search about this and test this first thing tomorrow (Netherlands) and let you know if it worked, thanks for the suggestion !
Edit: Didn't see the link you posted at first, but thanks for the reference as well!

Got the following exception.
"Cannot have a relationship between tables in different DataSets."
I could place everything in one DataSet, but it would be nice to know a solution when it's not possible to do so. I will try to build it like so that only one DataSet will be used for now, but is there a solution to my problem that works when multiple datasets are used?

Create a custom data object from the two datasets and bind the custom object instead of the datatable 
|
|
|
|
|
Oke thanks,
Im now working at the earlier hint to put it all in one dataset, but I think I am doing something wrong 
DataTable orderTable = dsOrder.Tables["Order"];
DataTable customerTable = dsOrder.Tables["Customer"];
dsOrder.Relations.Add("Order2Customer",
customerTable.Columns["customerID"],
orderTable.Columns["customerID"],
false);
this.view = (CollectionView)CollectionViewSource.GetDefaultView(orderTable);
this.DataContext = orderTable;(the added/changed code in C#)
<TextBox
Text="{Binding Path=orderID, Mode=OneWay}"
IsReadOnly="True"
Height="23" Name="textBox1" Width="Auto" Margin="3" />
<ComboBox
ItemsSource="{Binding Order2Customer}"
SelectedValuePath="customerID"
SelectedValue="{Binding Path=customerID}"
Height="23" Name="cbCustomer" Width="Auto" Margin="3" SelectionChanged="cbCustomer_SelectionChanged">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Source="Images/salome.gif" Height="Auto" Width="Auto" MaxHeight="40" MaxWidth="40"/>
<TextBlock Name="tbLastName" VerticalAlignment="Center" Text="{Binding Path=lastName}" />
<TextBlock Name="tbComma" VerticalAlignment="Center" Text=", " />
<TextBlock Name="tbFirstName" VerticalAlignment="Center" Text="{Binding Path=firstName}" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ComboBox>(an example of my combobox and a textbox I use in XAML.)
The TextBox binds correctly, the comboBox does not. The relationship should work like this right? But it can't seem to bind to the customer fields...
