PictureBox Control Not Display Bitmaps Specified Via Image Property
Mar 30, 2010
I am writing a VB 2008 Express Edition application which has multiple forms. All of the forms contain one or more PictureBox controls. All PictureBox controls have assigned bitmaps via Image property during development mode. So far, all the bitmaps displayed during runtime without a slightest problem. Now, suddenly, not a single new one (i.e. which I add from this moment on) would display bitmap during runtime. All the old ones (i.e. those which I have added up to that unspecified point in time when something went wrong) still display bitmaps fine as they did before. But any newly added PictureBox (or, come to that, any other control which can display bitmap.
I have tried also Label control) displays the bitmap loaded via Image property only during development mode. During runtime the PictureBox shows as empty. I tried to load the bitmap during runtime via command Image.FromFile and that works fine (but I don't want to use this approach in my program). If I create a completely new application, all PictureBox controls display the bitmaps just fine. I don't get any errors or warnings in VB editor. I reinstalled the whole VB 2008 Express Edition including SP1 and .NET 3.5 SP1 with no difference whatsoever (as would be expected as any new application works with PictureBox controls fine).
I am trying to create an If Then statement to test against the PictureBox.Image property. I want it to test if one image is selected and if so then to switch the image. This is what I have:
If PictureBox.Image Is My.Resources.Image1 Then PictureBox.Image = My.Resources.Image2 Else[code]....
I am trying to figure out how to make Alt + Clicking on the picture generates this response.
I am in the process of creating a relatively simple "yahtzee" game for a final class project. I have a "Roll the dice" button on my form that when clicked chooses 4 random numbers 1-6. Each number is a seperate "dice", each of the 4 pictureBoxes is meant to represent a seperate dice. A series of If then statements is being used for each picture box so that for example The random number is 1, a image of a dice facing the 1 side is displayed.[code]...
I am trying to work out a method to reset the image property of my picturebox on the fly.
I am able to load the original image from a file. But i want to save a clean copy of it before i draw on it. Between drawings i want to be able to reload it.
Here is what i have tried
Dim img as image Using OpenFileDialog1 As New OpenFileDialog With OpenFileDialog1
[Code]....
the code does not seem to work it just freezes. Im not sure exactly whats going on with it.
I'm trying to update pictures boxes with images of controls stored in an imagelist owned by a control. The images stored in the control.imagelist do not showup in the picturebox. I'm working on simplifying the code to post, but for now could use help.If I store the image in a member variable owned bythe control it woks fine.Something to do with persistance of images in control owned imagelist? [code]
i am creating a table in vb.net code (htmltable) with htmltablerows and htmltablecell. I gave on image control but thatr control cant have the .imageurl property, which i need cause i have a handler image.ashx which brings image from the database. heres' the code -
TD = New HtmlTableCell Dim img As New HtmlImage() img.ID = "image_" & rd("ID")
[code]....
on the last line, "img.ImageUrl" i get this error -'ImageUrl' is not a member of 'System.Web.UI.HtmlControls.HtmlImage'how do i fix this?
I have a picture box on my form. I can load images which I read from a database into the box.
The problem is that the images are all sorts of different shapes and sizes. Some are square. Some are portrait. Some are landscape.
How do I configure the imagebox so that the pictures are reduced to fit, and keep their proportions. As I've got it at the moment, the rectangular ones are distorted into a square, which makes some of them look pretty strange.
On my form i have a picture box that i want to put a random image in. im my code i have a random number generator. the number generated will correspond to a picture in my.resources. i.e if it generates 1 there will be a file called 1.jpg. what i need to know is how to tell the picturebox to display the image that corresponds to the generated number? i tried:
dim pic as string = random picAnimal.BackgroundImage = My.Resorces.("& Pic &")
this does not work, it says identifier expected (between the . and the vairable), can anyone point me in the right direction?
I am trying to have my application display an image in the picturebox named picResult based on whether or not a person gets the answer to a math problem right. How to load a smiley face image (happy.png) or a sad face (sad.png) into the picResult picturebox when the question is answered right or wrong? Here is my code that check the answer:
Code 'btnSubmit instructions Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click 'Error message displayed if textbox is left blank If txtAnswer.Text = "" Then [Code] .....
Code: Private Sub cmdNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdNext.Click Dim strURL As String
[Code]....
Am I doing this correctly so far? I need to "collect" the address/URL of the picture that is currently displayed in the picturebox (pbxFile), then load the next picture in the folder into the picturebox.
Fetch the image in mysql database and display it in the picturebox.i have a fieldtype mediumblob on my database.i cant move on with the application i develop.
I'm having a problem with making the Picturebox Transparent to the a Image layered underneath I'm getting tranparent to the form background color. Is there a Visual Basic Code Solution to achieve these properties? I used the imagebox in Visual Basic 6 and had no problem with this.
i know how to display an image in a picturebox by drag drop. but cant find anything on the net about dropping an image to a textbox then having the textbox display its location
reolved if any one else searches for it. Dim Files() As String = CType(e.Data.GetData(DataFormats.FileDrop), String()) Dim fileDetail As New System.IO.FileInfo(Files(0)) txtFilePath.Text = fileDetail.FullName
I'm real new to VB and thought I'd try something "simple". I have a form with a button, two pictureboxes and textboxes. When the button is clicked, I am generating two random numbers (1-6) and then want to select a corresponding picure of a dice from the Resource folder (named Dice1-6.jpg) for each of the pictureboxes. The textboxes display the numeric version of the "dice" rolls.[code]...
I'm using VB 2008 express to create a windows form application. I have a combobox named cb_face. The items in the combobox are image file names populated from my resource folder using a "for each" loop. When an item is selected I would like to display the image in picturebox1. I have tried several different codes but none of them display the image. I am not getting any errors. The comment lines show some of the code that has been tried.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim ImgFolder As New IO.DirectoryInfo("C:Documents and SettingsubdMy DocumentsVisual Studio 2008ProjectsBlank OutBlank OutResources") Dim ImgFile As IO.FileInfo() = ImgFolder.GetFiles("*.bmp") Dim info As IO.FileInfo For Each info In ImgFile [Code] .....
I want to know if there's a faster way to draw images onto a picturebox based on a list of point.
vb Dim MyPoints as New List(Of Point) Dim MyBitmap as New Bitmap("C:MyBitmap.PNG")
[code]....
Now, This code may be a little sloppy, but I just put it together. The image isn't very simple, but it's simple enough. After about 10 images that need to be drawn, it starts to get slow.What would I need to do to ensure it draws the images faster? If I made the image itself smaller would it make it go faster?
When adding an image to my form i can see it in the editing mode but after execution no not all images some ones display and others no it is really weird even if they have the same type png or jpg
I have 52 listview items in my listview1 and I have a picturebox basically I want it where I can click on a single item in the listview and display an image from a url in the picturebox. I basically have it right now that when you click on any item in the listview it just shows the same image in the picturebox no matter which item it is. I need to figure out how to do it separately for each item.
I have a picture box which reads in an image from a folder to display, instead of having the usual boring image I thought it may be nice to have a number of images in the folder and let my vb.net program randomly pick one out to use.
Is there a way to tell the DISPLAY size of an image in a picture box? If the PictureBox.SizeMode=Zoom, the picture sometimes is not displayed as big as the picture box is, and is sometimes displayed smaller, or larger, than the actual image is. I just want to know what size it is actually displaying as.
I'm new to VB.NET BTW. I designed a form and radio buttons and a submit button with a picture box ! Every radio button selected will display the image related to it in the picture box !
So, we have O smile O sad O mad O happy O ...etc When pressing the submit, the selected radio button will display a face of the mood !
Here is my code. If RadBtnSmile.Checked Then PicBxMood.load("smile.gif") End If If RadBtnSad.Checked Then PicBxMood.load("sad.gif") [Code] .....
If I replace an image in a picture box, should I dispose the original image first?
Or, what about this situation:
Dim bm As New Bitmap(32,32) bm = New Bitmap(32,32) bm = New Bitmap(32,32) bm = New Bitmap(32,32)
Does bm need only to be disposed at the end, or should it be disposed before each re-creation?
A big oversight there on my part. I knew a control took care of disposing its children but It hadn't occurred to me that I should dispose an old image if I replaced it.
Im doing a mini project and i need to display an image in picture box control when a cell clicked in datagrid view control .the image is linked through the database ms access and im using vb.net frame work.
I'm inexperienced with windows forms (vb.net), and I have a rather silly question.I'm opening an old project of someone elses, and there's a PictureBox control on the form. The PictureBox has a photo, and I'm trying to find the location of the photo on the computer but can't find it.In ASPX, I can just look at the code behind and find out where the tags are pointing to (for the photo).The only code that exists for my object, with the image property is this: [code]
