I added a wpf app to an existing solution, and without changing ANYTHING, I compiled it and tried to run it. I'm getting an error stating that the EXE file can't be found. Does anyone know what the hell I did to make this happen?

----------

I recreated the solution from scratch, and that seems to be the only way I could fix it. What a crock. During the discovery and resolution process, the IDE displayed an invisible modal dialog and refused to let me do anything - including closing the IDE - because the (invisible) dialog was waiting for input. I had to use task manager to close the IDE.

I hate Microsoft.

RichTextBox UI elements animating??

_iobuf28-May-09 7:27

28-May-09 7:27

I have a RichTextBox in my app, which is inside a control that is composed of a grid with 2 columnds,
i.e.

<Grid x:Name="LayoutRoot"
        VerticalAlignment="Top" Height="Auto">
    <Grid.ColumnDefinitions>
      <ColumnDefinition Width="150"/>
      <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Border x:Name="bdrLeft" Height="Auto"
            Background="{DynamicResource SplitRichTextBoxRightSideBGBrush}"
            BorderBrush="{DynamicResource SplitRichTextBoxRightSideBorderBrush}"
            BorderThickness="1,1,0,1"
            CornerRadius="3,0,0,3"
            VerticalAlignment="Stretch">
      <ContentPresenter x:Name="cpRightSide"
                        VerticalAlignment="Stretch"
                        HorizontalAlignment="Stretch"
                        Margin="0,0,0,0"
                        Width="Auto"
                        Height="Auto"
                        TextElement.Foreground="{DynamicResource SplitRichTextBoxLeftSideForegroundBrush}"/>
    </Border>
    <Border x:Name="bdrRight"
            Height="Auto"
            Grid.Column="1"
            Background="{DynamicResource TextBoxBGBrush}"
            BorderBrush="{DynamicResource TextBoxBorderBrush}"
            BorderThickness="1,1,1,1"
            CornerRadius="0,3,3,0"/>
    <RichTextBox x:Name="rtbMain" 
                 HorizontalAlignment="Center"
                 FontSize="{DynamicResource DefaultFontSize}"
                 Height="Auto"
                 BorderBrush="Transparent"
                 Background="Transparent"
                 Foreground="{DynamicResource DEFAULT_Font_Dark}"
                 VerticalAlignment="Center"
                 AcceptsReturn="False"
                 AcceptsTab="False"
                 Style="{DynamicResource ClearRichTextBoxStyle}"
                 Grid.Column="1"
                 Margin="0,3,0,3">
      <localControl:EnabledFlowDocument x:Name="efdMainDocument" PageWidth="{Binding ElementName=rtbMain, Path=ActualWidth}"/>
    </RichTextBox>
  </Grid>

All the animations in the code are set to 00:00:00.00

However, when I add a UIElement or even text to the FlowDocument on startup, the text/uielement appear in the center of the flowdocument, then animate over to the left side where they should be. Is this a bug in WPF? I can't find anything in my code that would cause this.

Need help populating a treeview with XML

Etienne_12328-May-09 6:34

28-May-09 6:34

Hi
Is there a way to populate a treeview using XML in WPF? Or by using the .xsd file?
If yes, please give me advice on how to get started. I've tried binding the treeview to the database using Hierarchical Datatemplates etc. but that still does not do the trick if you want multiple children nodes.

Mark Salsbery28-May-09 11:22

28-May-09 11:22

How about a short sample of the XML you're working with along with
how you're trying to bind to that XML...

Is the XML data actually hierarchical?

Also, searching on "wpf treeview xml data binding" yields tons of examples.

The thing is, I don't have a XML structure yet, I'm using a typed dataset which was generated for me by adding a datasource via the Visual Studio wizard, so I first have to generate a XML file from my typed dataset, and then bind it to the treeview. Here's a sample of what it might look like though:

<?xml version="1.0" standalone="yes" ?>
- <NewDataSet>
- <Products>
<ProductID>1</ProductID>
<ProductName>Chai</ProductName>
<SupplierID>1</SupplierID>
<CategoryID>1</CategoryID>
<QuantityPerUnit>10 boxes x 20 bags</QuantityPerUnit>
<UnitPrice>18</UnitPrice>
<UnitsInStock>39</UnitsInStock>
<UnitsOnOrder>0</UnitsOnOrder>
<ReorderLevel>10</ReorderLevel>
<Discontinued>false</Discontinued>
</Products>
- <Products>
<ProductID>2</ProductID>
<ProductName>Chang</ProductName>
<SupplierID>1</SupplierID>
<CategoryID>1</CategoryID>
<QuantityPerUnit>24 - 12 oz bottles</QuantityPerUnit>
<UnitPrice>19</UnitPrice>
<UnitsInStock>17</UnitsInStock>
<UnitsOnOrder>40</UnitsOnOrder>
<ReorderLevel>25</ReorderLevel>
<Discontinued>false</Discontinued>
</Products>
</NewDataSet>

This is obviously just a basic table showing some Products, the database I'm going to be using will have sub levels as well e.g. A Product(above) can have multple Parts assoiciated with it, so that needs to be shown within Product and for each Product

Etienne_12328-May-09 12:39

28-May-09 12:39

What I also want to know, is say for instance you have 2 tables; Categories and Products. And the relationship between them is one-to-many (A category can have many products). Is it possible to generate an XML file showing all the different categories as well as the products belonging to them hierarchically?

<Category id=1><br />
<Product id=1><br />
<name>milk</name><br />
<description>white</description><br />
<price>3.00</price><br />
<Product id=2><br />
<name>cola&/name><br />
<description>black&/description><br />
<price>3.00&/price><br />
<Category id=2><br />
<Category id=3>

Mark Salsbery29-May-09 7:00

29-May-09 7:00

The UI part is relatively easy - here's an example (not I've added some
Parts to the Products so there would be some hierarchical data):

<Window x:Class="WPFTester.Window2"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window2" Width="300" Height="250" >
	
    <Window.Resources>
        <XmlDataProvider x:Key="ProductData" XPath="*">
            <x:XData>
                <NewDataSet xmlns="" >
                    <Products>
                        <ProductID>1</ProductID>
                        <ProductName>Chai</ProductName>
                        <SupplierID>1</SupplierID>
                        <CategoryID>1</CategoryID>
                        <QuantityPerUnit>10 boxes x 20 bags</QuantityPerUnit>
                        <UnitPrice>18</UnitPrice>
                        <UnitsInStock>39</UnitsInStock>
                        <UnitsOnOrder>0</UnitsOnOrder>
                        <ReorderLevel>10</ReorderLevel>
                        <Discontinued>false</Discontinued>
                        <Parts>
                            <PartName>Part 1</PartName>

                        <Parts>

In real life your XML data is dynamic, but you can bind to dynamically created XML,
for example: How to: Bind to XDocument, XElement, or LINQ for XML Query Results[^]

Creating the XML is outside the scope of this message board, but if you're
relatively new at it, I'd really recommend learning a bit of LINQ.
Using LINQ to XML and possibly LINQ to Dataset you'll have a consistent way to work with
both Dataset and XML data. For example, you can use LINQ to query a multi-table
dataset and build a hierarchical XML representation for presentation.

Thanks I will have a look at LINQ. That sounds like it might do the trick.
So I guess there is no easy way to create a hierarchical XML structure based on a multi-table dataset. I though there might have been.

How to hook the ReadFile API like FileMon does.

30-May-09 0:14

I just found out that when you're using untyped datasets, then you can manually set up a relation between your tables, and then you just set the Relation's Nested property to true, then when you generate an XML file it creates a beautiful hierarchical structure, just the way I want it.
BUT, I'm using a typed dataset, which means the relations are created for me. Is there a way to manually edit these relations?

Don't react to quickly Pete. "maa chuda" is actually a South Glaswegian variant of the phrase "my chum" which means literally "he who is a friend of me". Used in this context the speaker is welcoming you into his inner circle of friends and thanking you for your help.

The believe traditional response is "och I"

I can see how that might have confused you.
