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? This is the code I used for the picture box:
PictureBox1.Image = My.Resources.tropical_island3
I ran into a similar problem on a VB.NET form. I found when loading the form as a modal window (.ShowDialog) the image in the picture box showed fine, but if loading the form as non-modal (.Show) the PictureBox showed with a white background.
To resolve showing the image in the non-modal form, I needed to call .Refresh for the form after the .Show
Hope that helps someone else!
This is a possibility, based on the limited info:
If the image is shown in the picturebox before you run the form in debug mode, then it apparently has been assigned at design time to the PictureBox1.Image property. When you run the program and assign My.Resources.tropical_island3 to the Picture Box image, it clears the image because My.Resources on your home computer does not have tropical_island3 like the one at class, or maybe tropical_island3 is spelled incorrectly.

I am a developer trying to make an operating system in VBA. On the login screen, there is a password box. I would like to make it transparent so that the user can see the UserForm's bitmap image through the text box. Is this possible. I'm also starting out on this project so a bit of help/explanation would really help please.
Kind Regards,
J
You can do this by changing the BackStyle property of the TextBox.
Let's say you're using VBA in Excel; you can make TextBox1 transparent by changing BackStyle to 0.
ActiveSheet.TextBox1.BackStyle = 0
Changing the property to 1 would render the TextBox opaque again.
I have A pictureBox in a form
I have declared a Picture box called Then
Field.Image = Image.FromFile("C:\Users\ABK\Desktop\Othello\field.png")
Field.Size = New System.Drawing.Size(483, 610)
Then I added the picbox to the form but when i copy the exr into another computer I don't see the picture
when I copy the exe into another computer I cannot see the picture
how can I include it in the exe file
Please try to keep the answers as simple as possible and demonstrate with examples
click on your form.
the properties tab should be on the bottom right
find image or background image and click on it
click the ... on the right side.
image as example of instructions above
a menu should show up.
Click import then select the file you want saved,
then press open it should go back to the menu,
select (none) to set your form image back to normal,
image as example of instructions above
then press ok,
go back to your code and change
Field.Image = Image.FromFile("C:\Users\ABK\Desktop\Othello\field.png")
to Field.Image = My.Resources.field
This should keep the image when you give it to your friend
I am using vb.net 2008, I added a button from design view in one of my forms.It shows in the form design view, I gave it the click code to load another form but after I run the program and look in that form, it does not show the button that I added while I run the program. what is the problem? And What are the solutions?
Thanks!
As you can see, I added a Back Button here
THis image is while I run the program. Back button is not displayed here.
I would suggest running something like this in order to see if the control is there. Listing if it is Visible would also be helpful.
https://stackoverflow.com/a/12985464/7340880
Private Sub GetControls()
For Each GroupBoxCntrol As Control In Me.Controls
If TypeOf GroupBoxCntrol Is GroupBox Then
For Each cntrl As Control In GroupBoxCntrol.Controls
'do somethin here
Next
End If
Next
End Sub
The only way I can help you without you providing us more information like code or error info if exist (or maybe a warning), I will suggest you to copy the code from your button then delete the current button and a new one. Then paste the code back to new button.
And make sure you don't hide or change the visible property button somewhere in the code. If you are working with positioning in the code make sure you don't move your button.
Thank you for your support. The problem was that it was running the old .exe file. I deleted the old .exe file from the /bin/debug directory. And after I ran the program, it created me a new .exe file and hence my problem was solved.
Thank you again.
I am using "ImageLocation" property of PictuerBox to get a picture from the web.
PB1.ImageLocation = "http://www.example.com/picture.png"
Some times the image which has to load in picture box from web is very large in size and can not be appear instantly in PictureBox. I need to conform that Image has successfully loaded in Picturebox, before performing next operation.
I have to Enable some controls just after loading of image from web.
Is there any way to conform this?
(Note: My PictureBox has an initial image also.)
Use the PictureBox.LoadCompleted event.
Okay see what I did for mine was just download the picture. The image normally takes a while to start getting put into the picture box.
Here is my code:
If (My.Computer.FileExists("http://www.example.com/picture.png")) Then
My.Computer.Network.DownloadFile("http://www.example.com/picture.png", <Some Location>)
PB1.ImageLocation = <Some location>
Else
End
End If
It may not be the most efficient way - but I can see it as a simple way of making it work.
Dunno if it's working or not, can't access Visual Studio at the moment
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).
Is there a way to do that for vb.net?
Update:
The only code that exists for my object, with the image property is this:
Me.pbTotal.Image = CType(resources.GetObject("pbTotal.Image"), System.Drawing.Image).
You can rightclick the picturebox -> Properties-> and there should be an image field with the informations you search
If its not set in the properties window which can be viewed by right clicking on the picture box it will be set in code using the image property.
The PictureBox control gives you two options for setting the image that is displayed on it. You can use the ImageLocation property or the Image property to perform the same task.
If you set the ImageLocation to the file name or url of a valid image/picture, image gets displayed and you can access it via the Image property as well. If you should use the Image property to set the image displayed, there will be no way to know the physical location of the image being displayed if you did not know it beforehand.
From the code you've pasted in your question, there no way way retrieve the path/url to the image file. To further complicate matters, the image is being loaded from your project's resources so any attempt to resolve the path/url would have to first go through the project resources before locating the original file and even if this is possible, for all practical purposes it is too cumbersome.
In short, if you'd like to get the path/url of the image loaded in the PictureBox at some point later, use the ImageLocation property instead of the Image property to set the image to be displayed.
Ok, I just found the true answer. Yes it in a resource file, but not for the project itself. I didn't know that forms themselves have resource files (.resx) as well.
In visual studio 2010 (not sure about the others), the .resx file is hidden. If you click the option to "Show All Files" in the solution explorer tool bar, you'll then see that the form can be drilled down. There in the .resx file, I was able to find my image.
