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'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.

View 3 RepliesI 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.

View 17 RepliesSo my program is supposed to lookup the image name from a database and display it in the form. Here's the
name = rs.Fields("image").Value.ToString
If Not IsDBNull(rs.Fields("image").Value) Then
If rs.Fields("image").Value = "" Then
Else
PictureBox2.Image = Image.FromFile("\MY.IP.ADDRESS.HEREwwwrootimagesproducts" & name & "")
End If
[Code]...
Now here is the problem: If the database returns the image name but the image cannot be found in the path specified, the app crashes. Is there a way to write an If statement to check if the image file exists in the directory specified?

View 2 RepliesI'm trying to recreate this feature for a twitter control program using VB Studio 2008. I want the users to be able to sign up their account in my application so they don't have to go to the site and do it.
Because captchas are dynamic images, I cannot pull the image from a src file. I'm pretty new to vb.net so, how would I initiate a session, with the webbrowser control or webclient, and be able to display the captcha image for that session on my form.
I'm using VB 2010, accessing a MS Access database. I have constructed a simple Windows Form returning data from the db, one field of which has a reference to an image I'm trying to display together with the data from each individual record.
I have a field with a product number, that matches the jpg file name (ie, the product number 5505 matches an image that I want to display, namely 5505.jpg). I've even created a new field in the db called 'Image', that contains the full name 5505.jpg.
So, I've connected to the db with an OleDbAdapter, and all the data fields are displayed via bound textboxes. I've been able to display a single 'set' image with a PictureBox, but I'm not sure how the make the connection between the returned data (txtSearchImage which is, say, '5505.jpg'), and getting the Windows Form to display this.
Am I on the right track using a PictureBox? I've tried binding this via the PictureBox properties to the relevant data field, but (obviously) it doesn't make the connection to the image file on my hard drive.
Here's my code so far:
Public Class Form1
Private Sub btnSearchKits_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchKits.Click

I am an experienced programmer but mainly in 4GLs and assembly. Relatively new to VB programming, especially GUI applications. On a form I need to create an area that will be used to display *extremely* large TIFF images. typical image size would be 2000 pixels by 100,000 pixels. Typically I will NOT want to display the entire image at once, so the area will need to have scroll bars and/or other methods to scroll/pan around the image.
I have read about and tinkered with the bitmap and picturebox objects, including some threads about several different ways to implement scrollbars. However, I see that the picturebox size is limited to 32K pixels in both dimensions. I suppose that I might be able to copy various portions of the bitmap to the picturebox depending on scroll position, but that seems potentially quite slow and cumbersome. Can an expert developer who is experienced with these types of issues regarding the following:
1. Can bitmap objects be used effectively with TIFF images of the size I am working with?
2. an approach that should produce reasonable scrolling performance for these extremely large images without excessive coding effort?
3. For an image that exceeds the picturebox size when displayed at 1:1 scale, is the picturebox capable of displaying a reduced size version of such an image without lots of code, and if so, how?
4. Many (most?) graphics display objects count on all of their display data being stored in memory rather than on disk. Would that be true of a TIFF image loaded into a bitmap object and displayed via a picturebox? If so, the amount of RAM required in order to buffer the entire image in memory could be a potential problem for images of this size. Is there an advisable way to have the picturebox or other display object only load portions of the image into memory on an as needed basis, and purge them once they are no longer required? Are there any built in objects/methods/properties or is there any sample code to show how to do this?

I made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.
Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?
