Interface And Graphics :: Animated Gif In Picturebox, Slow & Choppy?
Apr 3, 2009
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 having and issue with a VB.NET App that displays data derived from a database in a DataGridView Control. I am retrieving the data into a dataview and then setting the Grid.Datasource = oDView. On most machines it refreshes the data cleanly and quickly as you would expect.
I've problem with clearing all the drawings I've created in my PictureBox. In fact I've created animation which stops after certain time and remains on the screen. The animation is created/painted with collection of about 25 TextBoxes - input of a user. Now I've added a button which clears all that info in TextBoxes and also should clear PictureBox -ictureBox.Refresh(). The problem is when I add new info in 25 TextBoxes nothing appears in PictureBox and I can't start an animation. Wondering why...
i am making a program with graphics and im using a picturebox for a button. The image inside picturebox is transparent .gif. The problem is that i don't know how to make picturebox transparent. I searched the internet but all exaples didn't work. Does someone know how to fix this problem?
here is my problem i am making a blockbusters game and have come across a problem where 2 picture boxes overlap each other which i dont want so i need to make a picture box or a button into a hexagon shape so they wont overlap
I managed to combine two .png images into one, and then display the result in a pictureBox image.However, the pictureBox seems to scale up my image! Makes it bigger!The pictureBox size is 96x128. The two images I have combined are 96x128. The pictureBox's SizeMode is set to "Normal"I have noticed that even though the pictureBox's image seems to be zoomed, it is cut to keep the 96x128 rect. But I don't want it to be zoomed...
i'm working on Virtual K770i project - there is a picture of mobile, now i want to create clickable areas on "keypad" of mobile....I'm got idea about transparent label or something but transparency dont work on any object but Form1 - so how to make transparent clickable areas on picture box (see a picture)
I am currently creating an app and i want to be able to get the colour of a pixel, but in a picturebox.Example: I click anywhere in the picturebox and it will give me the color of the pixel I clicked.
I recently wrote an inherited picturebox control. From within the control inside methodI I call Me.Invalidate to fire the control onpaint event. But onPaint does not fire.
I'm making my first 2D game, and I've created an object inherited from a picturebox, to use as a little man. I've tried to make it move using a timer, but I'm not satisfied with the result. Sometimes the speed seems to change for no reason.
How do I rotate a bitmap image that has been placed in a picturebox? I need to make it appear upside down or rotated according to user input. I can't find anything in the properties to do this
I'm trying to update every millisecond the BackGroundImage of a PictureBox. But it don't works. I think that it comes from the figure that I update every millisecond in the PictureBox.[code]
Problem1: I have a picturebox on a form. I have also managed to draw several PNG files with transparency onto the picturebox (see below). However, If I move the form outside the border and move it back, the image is gone. My source so far:
Dim k1 As New Bitmap(My.Resources.image1) Dim k2 As New Bitmap(My.Resources.image2) Dim drawMe As Graphics = PictureBox1.CreateGraphics Dim bgcolor As Color = Color.FromArgb(128, 128, 128) drawMe.Clear(bgcolor)
My project needs to print a large PictureBox which during runtime only part of it is shown (as it's too large, width=4000 pixels and height= 2000 pixels) and to see the rest of the picturebox, user needs to scroll through the vertical and horizontal bars. On top of the picturebox, there are many controls which are loaded and positioned by user on run-time. Those include lines, labels, another picturebox with image and user-defined controls. Now, i need to write a print function which will print that picturebox to not too many pages in A4 size or A3 size. Not too many means less than 5 for both paper size.
1) How can i print the whole picturebox with all its contents and go to next printing page until the whole PictureBox is printed? I tried using the following code but
(i)The image of picturebox inside that picture box and user-defined control are not printed whereas others are printed. Why is that so? How can i print the picturebox including both the "un-printed"?
(ii) Even i can print out the picturebox, only the part where the picturebox is shown is printed. How can i print the whole picturebox including those parts which needs scrolling to reach?
Private Sub CmdPrint_Click() Dim rv As Long 'Picture1 is the picturebox to be printed.
The problem is that i am trying to resize pictures so they fit into a picturebox with good quality. I have found a code (se attached code) on the internet that resize the picture correctly but the quality is poor.
If i resize the picture in Adobe photoshop before i put it into the picturebox the quality is good so there is nothing wrong with the orginal picture or the picturebox. It's the resizing that is the problem.
Here is the code.
'Generate new image dimensions Public Function GenerateImageDimensions(ByVal currW As Integer, ByVal currH As Integer, ByVal destW As Integer, ByVal destH As Integer) As Size
I will get an error message. I tried something like
Code: Public ObjectPoint As PointF Dim cpoint As New PointF() cpoint.ObjectPoint = New PointF(startX, startY) e.Graphics.DrawEllipse(Pens.Blue, cpoint.ObjectPoint, 0.4, 0.4)
but it didn't work for the location and the circle size. How to draw a circle(and rectangle) by using floating point numbers?
Ive been working on creating a side scroller game, and the back color of my pictureboxes needs to go. when transparent, it shows through the program and onto whatever is active in your Windows os(usually Visual studios).
I am trying to rip pixel color off of the background image picturebox( the level), and replace parts of the character picture box that show transparency with the level art. there may be poor logic in my code?
Heres my code:
Dim newImage As Bitmap = New Bitmap(PictureBox1.Image) Dim backImage As Bitmap = New Bitmap(PictureBox2.Image) Dim ximg As Bitmap = New Bitmap(PictureBox3.Image)
[code]....
not the best idea, but all i get is one color for all the level pixels placed in the new image, which is odd. any poor logic you see in this code that could allow the newImage.setPixel not to be 1 color? when i breakpoint, it is recieving different colors from the backimage.getpixel, but only putting one shade on for setpixel somehow. im not going for an accurate color read from the background yet, just wondering why im getting 1 pixel color for the whole picturebox background when being changed.
i am drawing a string to a graphics object in the eg below and then transfering it onto a e.graphics in the paint event of a panel... when doing this the font edges appear dodgey...
Here is some
Dim b As New Bitmap(100, 100) Dim g As Graphics = Graphics.FromImage(b) g.DrawString("Bla Bla Bla", New Font("Comic Sans MS", 18,FontStyle.Bold), New LinearGradientBrush(g.ClipBounds, Color.Red,
First 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 have a picturebox with a animated gif,as yuo can see it goes up the bricks, 1,2,3,4 etc as it should when displayed in my picturebox it goes threw the bricks 1,3,5 then back round next time 2,4,6 and so on..is there some sort of delay?
I'm trying to get an animated gif picturebox to play and then after it is done "Playing" it will hide and show another picturebox. I thought I could do this with a timer but I can't really seem to get it to work. I need this in the form_load because the first picturebox shows on form load.
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)?
I wrote a little utility that compares pictures in a directory against each other and will display them side by side in two pictureboxes so the user can weed out duplicates. Anyway, seemed to be working fine until I started testing a directory that had animated gifs in it. The gifs will start playing in the form's pictureboxes, but at random (with no action taken by user) one of them will crash and give the attached error script. The other gif will continue running, but the offending picturebox will have the unrecoverable red "x", reloading or changing images does nothing after that point for that picturebox. As part of the apparent randomness, it will happen on either picturebox and the amount of time before it happens varies and does not seem to correlate to anything. For additional confusion, I have also seen where there is no error thrown, but both picturesboxes will suddenly go to the red x in the middle of a gif.
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

1. How can i make an animated gif to animate in a picturebox?
Picturebox1.Image = Image.FromFile("Loading.gif") 'it shows just one frame
2. Variables: ManagementObjectSearcher,Globals.getOnBoardDeviceStructure are not declared any suggestions?
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim searcher As New ManagementObjectSearcher("root\CIMV2", "SELECT * FROM Win32_OnBoardDevice")
Im working on a project that needs to print a report of one client.Everything went smooth untill i came across my multiline input text data.When i display it in the PrintPagePreview the text go's outside my page. Even when im printing it only the halve of my text is displayed. I googled and looked everywhere but i can't get a clear fix for it.
I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.
drawing text on a window which is not the current form's window.I remember doing this in Win32 api with getwindowdc(handle) to obtain a DC for the Window, then textout() on the DC.
