VS 2010 OpenFileDialog - Loading Images Into PictureBox
Jan 7, 2011
I have a 4 pictureboxes for a database I made but having a problem with loading images in to the picturebox. On my form I have a picturebox, 1 button, 1 textbox, and 1 openfiledialog.
My button click event code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
OpenFileDialog1.ShowDialog()
TextBox1.Text = OpenFileDialog1.FileName
Pic1PictureBox.Image = Image.FromFile(TextBox1.Text)
End Sub
I can add pics but if I don't select any image (just close the dialogbox) I get an error and not sure what to do ..or what to add. Is there any code to tell it to just close..
i have a simple photo viewer application where i want the user to click a "load sequence" button and then i want something like a folderbroswerdialog to appear then the user can pick a folder with images in it then the images get loaded into the picturebox and the user can click a "forward" button to go to the next image in the sequence and a "backward" button to go to the previous image in the sequence, it's kinda like windows 7 photo viewer.
I want to load images into a picturebox, save them into a database and display them again in the picturebox. This is the code I'm actually having problem with:
Private Connection As String = _ "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:UsersclientDocumentsVisual Studio 2008ProjectsSavingsLoansCalc.mdb" rivate Sub UploadButton_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles UploadButton.Click [Code] .....
I'm getting this error message: "Type 'Connection' is not declared" On this line: oConn = New OleDb.OleDbConnection( _ New Connection().getConnectionString)
I'm trying to load this image file on a PictureBox but I get an "OutOfMemoryException was unhandled" error.
How do I allocate more memory for this? Or maybe use another container? My project's main feature is loading maps, unfortunately my boss wants to load the whole map and won't accept sliced version of the map.
How can i display images in a picturebox using For Loop. Actually i've tried it before but only one image displays x times. What should i do so that all images will display?
My app has scrolling images in the background and a picturebox on top. The image in the picturebox has transparent parts. How can It so that the transparent parts show whatever is belo the picture box, not the form background? I have tried taking screenshots and positioning them as background but this just freezes the app.
Dim ScreenSize As Size = New Size(154, 83) Dim screenGrab As New Bitmap(154, 83) Dim blank As New Bitmap(100, 300)
I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?
As you see the code given below is not very useful. Is it possible to shorten the code. Mousewheel back and forward give the same result (next image). Keydown cannot be configured.
Private Sub Images_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load count += 1 If count + 1 > ImageList1.Images.Count Then [Code] .....
I have about 100 PNG images stored in a Resource. Sometimes I need to have the same images in an ImageList, but I do not want to store the images twice in my application, so I add the images from the Resource to the ImageList during runtime when I need them.
Is there an easier way to do this than having 100 lines of code, like the small example below?
I am using the following piece of code to load images as thumbnails to a FlowLayoutPanel control. Unfortunately i get an OutOfMemory exception.As you already guess the memory leak is found at line
Pedit.Image = System.Drawing.Image.FromStream(fs)
So how could i optimize the following code?
Private Sub LoadImagesCommon(ByVal FlowPanel As FlowLayoutPanel, ByVal fi As FileInfo) Pedit = New DevExpress.XtraEditors.PictureEdit Pedit.Width = txtIconsWidth.EditValue
[code]....
Update: The problem occurs while loading a number of images (3264x2448px at 300dpi - each image is about 3Mb's)
Is there any efficient way to load all of the images that my program will use upon start-up such that when I load those images into pictureboxes during runtime regardless of what form I may be using, the images will load faster?Does that make sense?I've read about ImageLists, but do they actually load the images or is it just a way to manage image files?
I am currently new to visual basic and I am using Microsoft Visual Basic 2010. I am trying to create a small game in which i want to use 8 images. These images are imported in my resources under images as _0.gif _2.gif up to _7.gif. I could write code for each of the imageboxes individually but i prefer doing it in an array as shown below. As you can see I use the variable "i" to run a for, next loop. picbox(i).Image = My.Resources._1 So that not every time it loads the image. _1.gif but it loads the images _0.gif through _7.gif, based on the "i" variable.
For i As Integer = 0 To 7 picbox(i) = [Code] .....
Is it possible to load an *.ico file onto a PictureBox ? I know I can use : PictureBox1.Image = System.Drawing.Image.FromFile("C:MyImage.jpg") but I'd like to use an icon . I have tried some other methods that read "Icon" , but I failed . Up to now the only thing I have thought is converting the file format form *.ico to *.jpg , but I think that's ridiculous ...
Is it possible to load an image into a picturebox when that picture box is clicked? What would the syntax look like? It's an image that I already dropped onto the form that I would like to load into that picturebox.
i know this is probally a really simple question but i have looked through my book and all my notes and googeled and couldn't find a answer that suites my needs.baisicly i have a combobox that gets loaded on form_load, what i want to do is load the appropriate picture into a picturebox when someone selects a item from the combobox. what i cant figure out is how to get the picture into the combobox using code. all the images are saved in my debug folder for the program. picturebox.image = picture.png this is what i asumed it would be but have tried with parenthises, quotes and both and it dosent work.
I want to make a program similar to this one: [URL]. I already have the ListBox ready. But how do I load the images? The image name works like this: -File1.package -File1A.jpg -File1B.jpg So the .package is removed and A.jpg or B.jpg is added.
I am trying to get a picture box (that has a loading image .gif) to be visible while the program reads a text file and change visible to false when all the information in the file.txt is displayed in the textbox.
Here is my Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click PictureBox1.Visible = True If System.IO.File.Exists("C: est.txt") = True Then Dim objreader As New System.IO.StreamReader("C: est.txt") [Code] .....
I have on a simple VB form:Label1Picturebox1FilesysytemwatcherThe watcher watches the camera but only the first picture load after that it gets an exeption and the program stops. I like to continu see what I shoot, but don't want to push buttons on the laptop after each shot. That reason the the watcher is placed. The time between shoot is enough for thw display being completed. The code:
Private MyImage As Bitmap Private Sub FileSystemWatcher1_Created(ByVal sender As System.Object, ByVal e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Created
i'm working on a project right now and I need to create a graphic library.The game I'm experimenting with is an RPG; this project is expected to contain many big graphic files to use and I would prefer not to load everything into memory at once, like I've done before with other smaller projects.So, does anyone have experience with libraries such as this one? Here's what I've came up with:
Have graphic library files and paths in an XML file Each entry in the XML file would be designated "PERMANENT" or "TEMPORARY", with perm. being that once loaded it stays in memory and won't be cleared (like menu-graphics)The library that the XML file loads into would have a CLEAR command, that clears out all non-PERMANENT graphics I have experience throwing everything into memory at startup, and with running the program running with the assumption that all necessary graphics are currently in memory.
I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
I want to be able to click a picturebox with an image and then load 3 other pictureboxes with images and then be able to click one of those 3 images and have it show in a bigger picturebox. How would I go about doing this? If its to confusing I will attach an example project I put together.
The title is simple and to the point: I have two images, same dimensions that I want one to fade in over the other. How do I do this without locking up the GUI?
