Form Box Does Not Display New Background Picture Upon Image.FromFile ?
May 2, 2010
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 "

I am designing an app and I want to attach some pictures to my VB forms. I have used a picture box and the image is only visible before I debug. Once debugging starts, the image disappears.
How do I display the image when I run the debugger?

I made a simple RPG game for my project. I used windows form application. I set the background image of my form1 to a picture that is already a map. I used picture box for the MainCharacter and set it to transparent and I also put transparent background gif images whenever the keyevents.But my problem is, sometimes when I move the picture box using the keyevents, when the picture box passes through the background that has different color, you can see the boundery of the picturebox, and sometimes it is lag and cannot display the image in the picturebox. Im gonna work hard for this because the deadline of this project is next week. I am just a newbie and not good in graphics.

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 can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?

How can I programmatically reset my form background from a picture to a solid color. I have no trouble changing it to a picture or even changing it to another picture, but when I try to change it back to a solid color, it won't work.
me.backcolor=color.red 'OK
me.backgroundimage=my.resources.dog 'OK
me.backgroundimage=(none) 'error
me.backgroundimage=my.resources.none 'error
How do I reset it back to a color? It's stuck in a picture mode.

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.
Here's my code:
Imports System
Imports System.Drawing

I have a few problems i need to solve. Firstly, I am looking for a piece of code i can use to display a picture from a bank of pictures. It will work on the basis of generating a random number and loading a picture that corresponds to that number.
i.e. Dim RandNumber As Integer
Dim RandClass As New Random
RandNumber = RandClass.next(1, 10)
If RandNumber = 1 Then
Picturebox1.image = picture1
[Code]...
Secondly, can I then use subsequent picture boxes to display pictures from the same bank of images, without displaying the same image? Finally, I then need to be able to click the picture or a button beneath the picture to select it as an answer to a question and then the whole process starts again.

I added an image as the background image for a form in VB.net. When I run the program, after approx. 5-6 seconds, the image partially overlays itself, as in an offset overlay of the underlying image. I never had this problem in VB6, but I did have it the other time I used a background image on a form in VB.Net.

how i can refresh my main form background image once a user picks a different image as the background.I have 2 forms namely Form1 (main form) and form2 from where the user can select the image he or she would like to set as the background image of form1.But the problem is that after selecting the image file from form2,when form1 is opened the background image doesnt change and remains the same as before.Only when the user ends the program and re-runs it again the image changes.
I tried
Form1.reload()

Basically I'm trying to make a layout change on a form if a link label is pressed. My main form I want this on has a "default" layout with a background image in place. What I want to do is, name the link label "Plain Layout". When the link label is clicked, remove or "hide" the background image and replace it with the background color of "control". After this action is performed, I need the text to change back to "Default Layout" and "show" the image.

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 am already familliar with applying an image to a form background. My application has many in it, but I want to give the user the option of browsing for an image of their own to apply to a form. I don't intend to save the images as defaults or anything. Just the option to browse and apply to a form.
