  • Animated transitions in WPF

    - by arconaut
    I can't figure out what I'm missing here. Here's the problem: Consider a (Control|Data)Template with a Trigger that switches visibility of some inner UI elements. E.g. show a TextBlock when IsReadOnly==true and show a TextBox when IsReadOnly==false. Everything is perfect if you do this without animation - one or two setters would do the job. But what if you want a fancy animation? Then you would specify which animations to start in EnterActions and ExitActions. But the problem is what exactly the animations should do? Modifying width/height seems really ugly, because fixed sizes in WPF are almost always a wrong way to go and also it's absolutely unflexible. So far, the best I've come up with is modifying MaxHeight/MaxWidth to some extent, this gives just a little more flexibility but still seems brutal. How do you tell WPF to animate Width/Height of an element from 0 to "as much as needed"? UPD: Currently I do animate Opacity and RenderTransform, and it works. It's just that sometimes I'd like to see animations where elements slide around without transformation. This is not a critical question, but a quite interesting one for me.

  • WPF TextBox SpellChecking Problem

    - by Alex
    How can I change the spellchecking language of a WPF textbox to french using XAML? I tried this but it doesn't work. <TextBox AcceptsReturn="true" SpellCheck.IsEnabled="true" FontSize="12" BorderBrush="Blue" Height="100" Language="fr-fr" /> French is supposed to be one of the 4 supported languages for spellchecking in WPF so I don't understand why it doesn't work. I also tried fr-CA but it still won't work.

  • WPF Login Verification Using Active Directory

    - by psheriff
    Back in October of 2009 I created a WPF login screen (Figure 1) that just showed how to create the layout for a login screen. That one sample is probably the most downloaded sample we have. So in this blog post, I thought I would update that screen and also hook it up to show how to authenticate your user against Active Directory. Figure 1: Original WPF Login Screen I have updated not only the code behind for this login screen, but also the look and feel as shown in Figure 2. Figure 2: An Updated WPF Login Screen The UI To create the UI for this login screen you can refer to my October of 2009 blog post to see how to create the borderless window. You can then look at the sample code to see how I created the linear gradient brush for the background. There are just a few differences in this screen compared to the old version. First, I changed the key image and instead of using words for the Cancel and Login buttons, I used some icons. Secondly I added a text box to hold the Domain name that you wish to authenticate against. This text box is automatically filled in if you are connected to a network. In the Window_Loaded event procedure of the winLogin window you can retrieve the user’s domain name from the Environment.UserDomainName property. For example: txtDomain.Text = Environment.UserDomainName The ADHelper Class Instead of coding the call to authenticate the user directly in the login screen I created an ADHelper class. This will make it easier if you want to add additional AD calls in the future. The ADHelper class contains just one method at this time called AuthenticateUser. This method authenticates a user name and password against the specified domain. The login screen will gather the credentials from the user such as their user name and password, and also the domain name to authenticate against. To use this ADHelper class you will need to add a reference to the System.DirectoryServices.dll in .NET. The AuthenticateUser Method In order to authenticate a user against your Active Directory you will need to supply a valid LDAP path string to the constructor of the DirectoryEntry class. The LDAP path string will be in the format LDAP://DomainName. You will also pass in the user name and password to the constructor of the DirectoryEntry class as well. With a DirectoryEntry object populated with this LDAP path string, the user name and password you will now pass this object to the constructor of a DirectorySearcher object. You then perform the FindOne method on the DirectorySearcher object. If the DirectorySearcher object returns a SearchResult then the credentials supplied are valid. If the credentials are not valid on the Active Directory then an exception is thrown. C#public bool AuthenticateUser(string domainName, string userName,  string password){  bool ret = false;   try  {    DirectoryEntry de = new DirectoryEntry("LDAP://" + domainName,                                           userName, password);    DirectorySearcher dsearch = new DirectorySearcher(de);    SearchResult results = null;     results = dsearch.FindOne();     ret = true;  }  catch  {    ret = false;  }   return ret;} Visual Basic Public Function AuthenticateUser(ByVal domainName As String, _ ByVal userName As String, ByVal password As String) As Boolean  Dim ret As Boolean = False   Try    Dim de As New DirectoryEntry("LDAP://" & domainName, _                                 userName, password)    Dim dsearch As New DirectorySearcher(de)    Dim results As SearchResult = Nothing     results = dsearch.FindOne()     ret = True  Catch    ret = False  End Try   Return retEnd Function In the Click event procedure under the Login button you will find the following code that will validate the credentials that the user types into the login window. C#private void btnLogin_Click(object sender, RoutedEventArgs e){  ADHelper ad = new ADHelper();   if(ad.AuthenticateUser(txtDomain.Text,         txtUserName.Text, txtPassword.Password))    DialogResult = true;  else    MessageBox.Show("Unable to Authenticate Using the                      Supplied Credentials");} Visual BasicPrivate Sub btnLogin_Click(ByVal sender As Object, _ ByVal e As RoutedEventArgs)  Dim ad As New ADHelper()   If ad.AuthenticateUser(txtDomain.Text, txtUserName.Text, _                         txtPassword.Password) Then    DialogResult = True  Else    MessageBox.Show("Unable to Authenticate Using the                      Supplied Credentials")  End IfEnd Sub Displaying the Login Screen At some point when your application launches, you will need to display your login screen modally. Below is the code that you would call to display the login form (named winLogin in my sample application). This code is called from the main application form, and thus the owner of the login screen is set to “this”. You then call the ShowDialog method on the login screen to have this form displayed modally. After the user clicks on one of the two buttons you need to check to see what the DialogResult property was set to. The DialogResult property is a nullable type and thus you first need to check to see if the value has been set. C# private void DisplayLoginScreen(){  winLogin win = new winLogin();   win.Owner = this;  win.ShowDialog();  if (win.DialogResult.HasValue && win.DialogResult.Value)    MessageBox.Show("User Logged In");  else    this.Close();} Visual Basic Private Sub DisplayLoginScreen()  Dim win As New winLogin()   win.Owner = Me  win.ShowDialog()  If win.DialogResult.HasValue And win.DialogResult.Value Then    MessageBox.Show("User Logged In")  Else    Me.Close()  End IfEnd Sub Summary Creating a nice looking login screen is fairly simple to do in WPF. Using the Active Directory services from a WPF application should make your desktop programming task easier as you do not need to create your own user authentication system. I hope this article gave you some ideas on how to create a login screen in WPF. NOTE: You can download the complete sample code for this blog entry at my website: http://www.pdsa.com/downloads.

  • Blender to 3ds max to cal3d format

    - by Kaliber64
    There are quite a few questions on cal3d but they are old and don't apply anymore. In Blender(must be 2.49a for python script to work!!!): I have a scene with 7 meshes, 1 armature, 10 bones. I tried going to one mesh to simplify it but doesn't change anything. I found a small blend file that was used for cal3d and it exported just fine. So I tried to copy it's setup with no success. EDIT*8/13/2012 In the last week here is what I have found so far. I made the mesh in the newest blender(2.62?) and exported it to import it in the old one(2.49a). Did an animation in the old one because importing new blend files to old blenders, its just said it would lose keyframe data and all was good. And then you get the last problem of it not exporting meshes. BUT I found that meshes made in the old one export regardless. I can't find any that won't export. So if I used the old blender to remake my model I could get it to export :) At this point I found a modified release of cal3d (because the most core model variable would not initiate as I made a really small test subject in old blender instead of remaking my big one which took 4 hours.) which fixes the morph objects and adds what cal3d left off with. Under their license they have to release the modification but it has no documentation so I have to figure it out on my own. Its mostly the same. But with this lib it came with a 3ds max exporter. My question now is how do I transfer armature and mesh information from blender to 3ds max in order to export into cal3d format. Every time I try the models are see through and small and there are no bones. The formats I have tried to import are .3ds .obj(mesh only) and COLLADA. In all of them the mesh is invisible and no bones. It says the default texture is on so I should be able to see it. All the vertices are present I found a vertex highlighter so I can see those. If any of this is confusing let me know so I can clear it up. Its late .<=sleep.

  • Disabling Minimize and Maximize buttons in a WPF Window

    - by marianor
    In WPF there is no possibility to control when the Minimize and Maximize buttons are disabled when the WindowStyle is SingleBorderWindow or ThreeDBorderWindow . In Windows Forms there are some properties like ControlBox , MinimizeBox and MaximizeBox that allow to do that. Because the WPF window internally has a hWnd we can do this using Windows API ( GetWindowLong and SetWindowLong will do the trick). I did three attached properties applicable to Window that use the internal API, in order to disable...(read more)

  • Wait for all WPF animations to stop

    - by Ray
    Given a WPF window, which may or may not have animations, I'd like to wait until they are all done before continuing processing. Is there a generic way to do this. Currently I can do something like this: void WaitForAnimation(Storyboard storyboard) { WaitUntil(() => storyboard.GetCurrentState() == ClockState.Stopped); } But this assumes I know the storyboards or have some way of finding them. Is there a way of doing that?

  • Raphaeljs animation kills my browser

    - by user1688606
    I have this code where I have a made a character using 20 paths and put it into a set. Now when I animate the set, the first transformation runs smoothly, the second animation stutters, the third animation doesn't happen as it should and the 4th animation kills my pc, the browser hangs and in the task manager I can see that it consumes up to 70% of CPU. How can I avoid this and free the resources so all the animations run smoothly. *I have to execute 10 simple y-axis transformation animations on that character. JS Fiddle window.onload = function(){ var paper = Raphael(0,0,400,400); var character = paper.set(); paper.setStart(); var attr = {fill:'red',stroke:'none'}; var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var character = paper.setFinish(); character.transform("t0,200") //1st animation.. var chartrnsfrm = Raphael.animation({ transform:'...t0,-48' },1000,"easeout",function(){ character.animate(chartrnsfrm1.delay(2000)) }); character.animate(chartrnsfrm.delay(2000)); //2nd animation.. var chartrnsfrm1 = Raphael.animation({ transform:'...t0,-48' },1000,"easeout",function(){ character.animate(chartrnsfrm2.delay(2000)) }); //3rd animation.. var chartrnsfrm2 = Raphael.animation({ transform:'...t0,-48' },1000,"easeout",function(){ character.animate(chartrnsfrm3.delay(2000)) }); //4th animation.. var chartrnsfrm3 = Raphael.animation({ transform:'...t0,-48' },1000,"easeout"); }

  • Make a animation path separated by clicks

    - by Tomáš Zato
    I have a long text on powerpoint slide. Instead of separating it on multiple slides, I made an animation that moves it up using animation path, so that text hidden at bottom appears while text on top goes off screen. However, I need more move animations to reaveal more text (the text takes more than 2 screens). This means, I need two (or more) animation paths (of the same length) and I want them to move obejct from position, where the last path has left it. Instead, multiple animations always operate with objects original position. That's useless. You can download test document, where I made an example of what I want: animation test.pptx

  • What is the WPF equivilant for the FlowLayoutPanel?

    - by Sargola
    I am working on a WPF application (a one note clone which is called "note your life") where you can dynamically assign Tags to an entry (just as in virtually any web 2.0 app these days). for this I had in my windows forms prototype a FlowLayoutPanel that did the job very well. I want to have the tags float to the next line if there isn't enough space and get a scrollbar if needed. how can this be achieved with WPF? I played around with <StackPanel Orientation="Horizontal" FlowDirection="LeftToRight" ...> but this doesn't move the elements in the next line if needed. Any suggestions?

  • forcing Validation; WPF, DataGrid, ObservableCollection

    - by Steve Mills
    I have a WPF DataGrid. I read a csv file and build an ObservableCollection of objects. I set the DataGrid.ItemsSource to the Collection. I would like to then force a RowValidation on every row in the DataGrid. If I, playing user, edit a cell, the RowValidation fires, all is well. But the Validation does not fire on the initial load. Is there some way I can call ??ValidateRow?? on a row? on every row? (C#, WPF, VS2008, etc)

  • Winform custom control in WPF

    - by Erika
    Hi, I'm inserting a custom winform control in a WPF/ XAML window, however i'm realising that the sizing seems to be very different, what i designed in winform to be 730pixels wide for instance, when placed via a WindowsFormsHost, in a container 730pixels (or at least i think they're pixels..) wide, the control looks much larger and doesnt fit in the host and results in clipping from the right and bottom. Would anyone know how to make these sizes match or something? I'm really at a loss and its very difficult to fix a custom control to make it look as it should off hand on WPF! Please help!
