I was wondering if there is a library or code snippet available for .NET (or that I can translate to .NET) to display animated PNG files (on the Graphics object, or even in a custom control)?

how to specify a custom icon for display in the toolbox window when you create your own custom control? Something other than the dreaded "gearbox" icon.
View 2 RepliesFirst part of a huge block will contain some text. That block is not always visible. it will be visible when the user is inputing a control. It is drawn in a bitmap image which will later be a part of the final image of the form.The second part consist of several small bitmap images most probably will contain a letter. These images will not change but there position will keep changing by time. These images will be free to move even beneath the huge block (If visible).I used a timer with 1 sec. interval to redraw form, but when the block is visible it keeps flickering because the timer clear the form and redraw the block.
I tried to use different container for the block like the PictureBox but when the small image goes beneath the block it just disappear.The block color code is "Color.FromArgb(100, Color.Black)" I tried lower Alpha components and that didn't make any difference.My explanation is that the background of the picturebox is not transparent. If I'm right how to make the picture box transparent?
I'm trying to build a dial control as a custom user control in VB.NET. I'm using VS2008.so far I have managed to rotate image using graphics.rotatetransform . however, this rotate everything. Now I have a Bitmap for the dial which should stay stable and another Bitmap for the needle which I need to rotate.so far i've tried this:
Dim gL As Graphics = Graphics.FromImage(bmpLongNeedle)
gL.TranslateTransform(bmpLongNeedle.Width / 2, bmpLongNeedle.Height * 0.74)
gL.RotateTransform(angleLongNeedle)[code].....
As I understand it, the image of the needle should be rotated at angle "angleLongNeedle" although i'm placing the rotated image at 0,0. However, the result is that the Needle doesn't get drawn on the control.
I'm trying to build a custom ListBox control as inspired by the 'Audi Infotainment System' on high-end Audi vehicles. The only difference is i would like to have a 'boundary' where when scrolling up/down moves the actual list up or down. Basically, i would like my list to act like a normal ListBox except i would like to show say one or two items above and below normally only visible items.
View 3 RepliesI have created a custom user control (JCUserControl), and I am using it in the Main Window. And my Main Window has no codebehind. I have this in the JCUserControl codebehind:
Private Sub ImmediateRadioButton_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles ImmediateRadioButton.Checked
SomeTextBox.IsEnabled = False
End Sub
When I run it, it fails with the NullReferenceException. If I comment out the SomeTextBox.IsEnabled = false, it runs without any problems.
Edit: Found out that I could just check if the radio buttons are loaded before doing whatever I want to do.
Private Sub ImmediateRadioButton_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles ImmediateRadioButton.Checked
If ImmediateRadioButton.IsLoaded Then
SomeTextBox.IsEnabled = False
End If
End Sub
I've been searching for days. I can't find anything that I think is going to work. I've probably read the answer and skipped it because I don't get it. I'm new. I've researched multithreading, sub routines and webbrowser. The webbrowser thing doesn't seem professional to me.
All I want is the animation to be smooth when it's displayed and to have it integrated into the app so it's not called from the local drive.The animated gif is in PictureBox3. Please point me in the right direction. I really don't want to use a static image.

I am trying to acheive something similar to this in VB:
Basically, I just need to be able to put in an animated cursor, and it can't be GIF it needs to be 32-bit transparent, so ANI format.
I'm using a PropertyGrid to display properties of my custom object, but whenever I run the form and input stuff into the collection, it doesn't save... If I open up the CollectionEditor again, its blank.. heres my code

I don't usually use VB but now I must for an assignment. I would like to know if it's possible to change the display name for an object on a listbox. For instance, if I add to it a user defined class, there's a way to provide it's display name, instead of converting it to string and then add it.
This is what I have
Dim format As String = FormatOutput(object)
Lista.Items.Add(format)
I would like to have the same output, but instead add the object.
Note: if such is not possible, then how can I associate the list box selection to the actual object? Doing it by index is painfull, because I'm using linked lists (ie., instead of arrays).
Note 2: python has a __str__ method which is called by default when the object is cast to string. Is there anything like it in VB?

I'm an amateur programmer who's learned quite a bit from online references, and usually searching eventually reveals the problem but I'm stuck!I've overcome many obstacles when creating a custom button on the Ajax Editor control, namespace issues, registring the controls properly etc. I resist the temptation to ask for help because the errors should lead me in the right direction. Now I get no errors, but the control isn't visible! The tag is in the .ASP page and I even set the width, height and visible tags in case it's being hidden but nothing shows up.

My question is on how custom controls should be updated.
I downloaded this owner drawn custom control, which I built, then copied the DLL to the Debug folder of the project and loaded it into the toolbox from there.
I decided to use this button on another project. I was mildly surprised to see the control was still in the toolbox but it seemed to work just fine. I decided to change this custom button's behavior. The button in the toolbox referenced the old version number. So I deleted it and loaded the newly rebuilt DLL.
Now come the problems. The first application--the one where the DLL was added to the toolbox from--still runs okay, but the second application is throwing errors, saying, Type 'CButtonLib.CButton' is not defined. When I add the button to a form, it appears okay. I can change its properties and it shows up in the code windows and in the object browser. But as soon as I try to run it and it throws the errors, it no longer appears in the object browser. References in the code window lose their intellisense.
Things I've tried include:
Copying the DLL to the project's debug and release folders and loading them into the toolbox from there. Removing it from the toolbox altogether and just adding a reference then copying and pasting a button directly from the first project. Copying in a form with a CButton on it from the first project.

is there any easy way to display animated gif in sys tray?
or do i have to draw a simple picture/shape using GDI ?

I have a page that allows users to "upload" a file. The page includes an asp.net fileUpload control. However, all it does is send the byte array to a WSE 2.0 web service. I can't change this. This may be updated in the future, but for now, this is what I have to go with.The page has an animated gif that starts when the user clicks the submit button. And the page should be updated accordingly based on the result returned by the web service call. I'm able to start the gif and consume the WS successfully. However, while the page is hitting the web service, the gif file freezes.
I then tried to use a separate thread to consume the web service. This speeds up the process and does not freeze the gif, but the page is not updated when the web service completes. If I put the main thread to sleep, the page updates, but I'm back to the same issue mentioned above, where the gif freezes. I'm pretty sure I could make the call using javascript and update the page that way, but at this point, I'd really rather do it server side (out of stubbornness if nothing else).
I'm a moderate (self taught) skill level programmer, developing a piece of software to display information on a Large-screen LCD Display using VB.Net 2008 in Visual Studio 2008 Pro, this is a WinForms project targeted for the .NET 3.5 framework.I have a WebBrowser Control (docked into a disabled panel on the form) which is used to playback a powerpoint presentation, on a fullscreen, borderless form.I need this to be resizeable/ movable, depending on the other information I need to display. If I just resize/move the control, but looks horrible, so I would like to animate this resizing.The WebBrowser control will be, by default, in the top right quarter of the screen, resizing to fill the screen as and when needed (so the control will need to scale up in size, and move left at the same time).I've tried to loop through a resize in increments, but the browser resize flickers, although the powerpoint inside it appears to look OK. Is there any way to make this a nice, smooth resize, without the flickering?

View 2 RepliesHere's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.
I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.
I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D
[CODE]...
The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.

I'm having some problems with custom controls and anchors today. I made a custom control containing a picture box and a vertical scroll bar. When I adjust the form the custom control outer area (the blank part) will adjust to the size of the form but the picture box and scroll bar do not. I have the picture box anchored to all sides and the vertical scroll bar anchored to the right side. They just will not adjust with the control when it is resized on the form.
View 4 RepliesI'm trying to bring up a simple right-click menu on a listbox and I'm having little luck with it. I created a basic ContextMenuStrip named "ContextMenuStrip1" and I'm trying to call it in the ListBox's Mouse Click method:
Code:
Private Sub ListBox1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseClick
If (e.Button = Windows.Forms.MouseButtons.Right) Then
ContextMenuStrip1.Show(MousePosition)
End If
End Sub
So here's what it's actually doing. The right mouse button doesn't seem to activate MouseClick at all for this object. It is caught in MouseDown, but when I try to call this from that method, the ListBox Index doesn't change. How can I get a right-click to be called from the MouseClick (Not imperative) and how do I get the ListBox to change the index with a right-click?Also, the menu looks like one of Office's right-click menu that can have an image to the left of the text. When I don't have an image the text is about 50 pxls or so away from the left edge. This looks weird. Can I change that?
