Differences PictureBox.ImageLocation And Image.FromFile()
Jun 20, 2009
I am a little bit confused about PictureBox.ImageLocation and PictureBox.Image = Image.FromFile().
The problem: If I use PictureBox.Image = Image.FromFile() then I am not able to do something with the file unless I dispose the PictureBox (which I most likely don't want to do).
If I use PictureBox.ImageLocation instead, I get the same result but I am still able to delete / move / overwrite the picture file.
So, just to get confused entirely: What are the differences between PictureBox.ImageLocation and Image.FromFile? When should I use the first, when should I use the second?Listing SPEC's is not a review !!! :-)
I'd like to hide the contents of a picturebox while still preserving it's imagelocation, width, height, borderstyle, top, left, and sizemod properties. Is this possible?
I am making a dice game, and just wondered why this doesn't work:'If dcpic1.ImageLocation = "D:Documents and SettingsAdministratorDesktopVBYaktzis in progressDicesone.gif" Then'
how else can I check the location of an image ?[code]...
How do get reference to the error image that is laoded by default if there is no image when using imagelocation I am trying to build an IF statement to only do something if picbox is not = error image
If PictureBox1.Image <> Image.error.system.drawing.Bitmap Then

I am trying to display a bitmap image and am having a bit of trouble. I am new to VB.net and its functions. Here is a few lines of code I am using REM load the bimap file
I've been trying to make an image viewer that keeps top most while I do other things (like typing, etc), so I don't have to hop windows, or sacrifice screen real estate.I made a main form, and a configuration form (opened by pressing o), with options to set the main form's opacity (working), the picture displayed (as the form's backgound picture, not working), and if the main form stays top most or not (working).
Instead, the form just keeps displaying the image I set in the IDE.I first used a picture box to display the picture, which did not work, and decided I didnt need to have a picture box if I set the picture as the form's background picture.I tried looking at what could be going wrong, but couldnt find out much more than the path is being delivered to the main form.I'm working on Vista Home Premium 32bit SP2, VS2003, and here's the code.PS The code links to a D:ath-fin.jpg that I used as the default background picture, and the code is for 2 seperate forms.
Public Class Form1 Inherits System.Windows.Forms.Form #Region " Windows Form Designer generated code " Public Sub New()[code].....
I'm trying to load a .ani file into a bitmap so it can be displayed on a control or on a form. The following code has been paired down from a short 'Download Sample' which I then edited to point to my .ani file. As indicated in the following code, I can load a .gif file, but I can't load a .ani file.
I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.
I drew an image in a picturebox with the image height as picturebox height and image width as picturebox width. The image is placed somewhere on the center of the picturebox. My intention is to scale the image to fit to the picturebox.
I have a program I'm working on that, for one of the features, allows the user to drag an image from a picturebox, into the main form space, anywhere they want. [code]...
When trying to drag the image from the CurrentTilePicBox, the very moment I move the mouse while dragging the cursor becomes a circle with a cross and won't drag and drop into the new picturebox.
I have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.
This works fine when I give the location of the image (the full path ) on my computer - but then of course it will not work if I use the solution on a different computer .
So I have made a folder named "Pics" inside my application and added two images into it.
How do I get to this local folder in the following code?
Picturebox1.image = system.drawing.image.fromfile (??? ) instead of the usual, Picturebox1.image = system.drawing.image.fromfile ("C:UsersMyName My PicturesMyPicture.jpg" )
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'm lost on this code.. i have a picturebox that swaps 2 images, depending on the action, file_red and file_green.. what i'm trying to to is, if a picturebox switches a image or not, to be able to detect that and have textbox8 add a line with the detection.
i have a image with four squares evenly spaced out. I want a picturebox's image to be one of the squares at a time so it's like a animation except it's only one image.
I have a PictureBox which I would like to check if it's the same as one already imported to resources . If it's the same it'd do a condition otherwise it's do something else .
If I try
If PictureBox1.Image = Jogos_Matem�ticos.My.Resources.Resources.Cross Then 'code here Else

in vb.net can i pan an image within a picturebox without having scroll bars at the side or a seperate form that comes up with the the image to navigate round, i just want to click on the image and drag around it to navigate it without a scroll bar or a seperate pan window.
Is there any way to set a picturebox's image from a url? My idea is something like "Picturebox1.image = Webbrowser1.(I dont know how to finish the code from here)".
