Re: Which obfuscator can I use? - WPF Discussion Boards

Hi friends,

I have made a small application using WPF. Now I want to obfuscate so that no one can steal my algorithms. Also so that no one can break my licensing mechanism.

I did try trial/free versions of some tools like Dotfuscator, Eazfuscator, Babel etc. But in these trial versions, my application get crashed while executing its one or other functionality. It might be because vendor don't want us to use application obfuscated with their free/trial versions.

Can anybody suggest me a free Obfuscator which provide reasonable/moderate security but no crash or serious bugs in obfuscated assemblies?

Thanks in Advance
Aseem

Hi Friend,

I found the same problems with NET NamesObfuscator what I found with others. Then I tried Babel. Its trial version is also causing crash to my application. But it has some option which we can turned ON/OFF. It served my purpose. I think Babel is a very good obfuscator. One problem with it is that it has a command line UI not GUI.

I'm sorry to tell you this, but if you have .NET code then it can be read - the obfuscated code makes it harder, but not impossible to break your algorithms.

Hi Pete,

Thanks for the reply. I know that I cannot do anything other than just making it harder to read and understand my code. But for my small application, it would be enough. Can you suggest me a free Obfuscator that can obfuscate the WPF code and providing reasonable security?

Path.. on buttons dissapearing [modified]

Hello.

I'm new on WPF. I'm trying to use a Path as content of a button. The problem is that using the same path on different buttons, the path is only visible on the last one created.

This is the declaration of the path on a ResourceDictionary

<Path x:Key="CloseGeometry" Fill="{StaticResource DefaultForeground}" Stroke="Transparent"
Data="M 4,4 L 4,16 L 16,14 L 16,20 L 30,10 L 16,0 L 16,6 Z">
</Path>

And this is how I try to use it like button content.

<Button Name="dataEndavantButton" Style="{StaticResource AppButtonStyle}" Content="{StaticResource CloseGeometry}"></Button>

What I'm doing wrong?

Thanks in advance.

Great question. If you are using 64Bit machine. It won't allow. Like you, I'm also having the same problem. I haven't checked it with 32-bit machine.

Binding MenuItem.IsChecked to RichTextBox.SpellCheck.IsEnabled

Hi,

I have the following deceleration of a rich text box:

<RichTextBox 
    x:Key="rtfBox"
    SpellCheck.IsEnabled = "False"
    ContextMenuService.ShowOnDisabled="True"    
    ContextMenu="{StaticResource rtfBoxContextMenu}">    
  </RichTextBox>

And the context menu is defined as a resource on the same xaml as follows:

<ContextMenu x:Key="rtfBoxContextMenu">
  <MenuItem Command="Copy"/>
  <MenuItem Command="Cut"/>
  <MenuItem Command="Paste"/>
  <Separator/>
  <MenuItem Command="My:MyCommands.ToggleSpellChecker" IsCheckable="true"/>
</ContextMenu>

I would like to bind the check box of the menu item to the state of the spellcheck isenabled property.

Please help. What minimal xaml/code is needed for that?

You could name the CheckBoxMenuItem and bind it via property path. Like

<ContextMenu x:Key="rtfBoxContextMenu">
    <MenuItem Command="Copy"/>
    <MenuItem Command="Cut"/>
    <MenuItem Command="Paste"/>
    <Separator/>
    <MenuItem Command="My:MyCommands.ToggleSpellChecker" IsCheckable="true" Name="menuItemCheckBox"/>
  </ContextMenu>

<RichTextBox 
    x:Key="rtfBox"
    SpellCheck.IsEnabled = "{Binding Source={StaticResource rtfBoxContextMenu}, Path=menuItemCheckBox}"
    ContextMenuService.ShowOnDisabled="True"    
    ContextMenu="{StaticResource rtfBoxContextMenu}">    
 </RichTextBox>

Hi,

I have a wpf rich text box that I open and show in a win32 application.

I declare the rtf box in a resource dictionary like so:

<RichTextBox
  x:Key="rtfBox"
  HorizontalScrollBarVisibility="Auto" 
  VerticalScrollBarVisibility="Auto" 
  HorizontalAlignment="Stretch"
  VerticalAlignment="Stretch"
 />

In another place, I have a wpf window which I use as a floating tool bar. I declare it in its own xaml, similar to the following:

<Window x:Class="BidiFix.SandBox.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
    mc:Ignorable="d" 
 Title="Window1" AllowsTransparency="True" Focusable="False" ShowActivated="False" ShowInTaskbar="False"
  SizeToContent="Width" Height="24" Topmost="True" Padding="2"
  WindowStyle="None" Background="Transparent" >

  <Border>  
   <StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Margin="2">
    <Button Command="Copy" Context="Copy"/>
    <Button Command="Cut" Context="Cut"/>
    <Button Command="Paste" Context="Paste"/>
    </StackPanel>
  </Border>
</Window>

I instantiate and show the window using the following code:

RichTextBox rtfBox = GetTheBox();
Window1 win = new Window1();
win.Show();

Now, as you can see I have both the rtf box and window available. But the window is not an ancestor of the rtfBox, nor do they share the same xaml.

What minimal markup and/or code is needed to connect the Clipboard commands and button states to the rtf box, such that they will reflect their availability based on the selection state in the rich text box and when click will operate on the rich text box.

Please help.

Hi,

I would like to easily record the changes made to the of RichTextBox (user and/or programmatic) as well as the changes made to the FlowDocument and be able to save and play them again.

I was thinking about the do/undo queue of the document. How do I get access to it?

Also, can UIAutomation or something like this can help me?

In short, can you to me what my options are?

Canvas, dragging, scrollbars and measureoverride

RugbyLeague26-Sep-10 23:09

26-Sep-10 23:09

I have a custom canvas control which sits inside a scrollviewer - I have implemented drag, drop and move for items on the canvas and overridden MeasureOverride so that when I move an item around on the canvas its size reflects the changes so if I move the item beyond the visible portion of the canvas it will resize to accomodate the moved item and scrollbars will show appropriately.

However if I then bring the item into view by using the scrollbars then start to move the item back out again the scrollbars go a bit haywire.

It's a rather poor explanation of the problem I afraid but I am not sure how else to put it but hopefully it will contain enough info for somebody to point me in the right direction.

Hi RugbyLeague,

I could understand the problem. You are having a visual studio designer like custom canvas control, in which you will be having controls. The problem is with scrollbar of the scroll viewer in which the canvas is hosted. Right?

RugbyLeague wrote:

Do you mean, the scroll bars of the scroll viewer not scrolling smoothly?
If that is the case. So far known best way is, You have to create your own calculation for updating the scrollviewer's vertical and horizontal offset.
