VS 2010 Function For Changing Picturebox Background Image With String?
Mar 1, 2012
What I have done is named a bunch of picture boxes "Q," "W," "E," etc. (the whole alphabet) and named picture that correspond to these picture boxes ("Q.png," "W.png," and so on) and added them to my resources.
For example, the following code would give the picture box named "Q" it's corresponding image "Q.png":
vb
Q.BackgroundImage = My.Resources.Q
Of course, it's kind of a pain in the backside to copy and paste this code and change all the Q's to W's and so on, so I was hoping to create a function to do the job for me:
vb
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
'So that I can run the letter as a string through the function,
[Code].....
Hopefully I've provided enough detail so that it is obvious what I'm trying to do.
Obviously, the code I tried above (the second block) doesn't work - it gives a syntax error. I need to change/write to make this function functional.

i have a program i've made a while, and one of the users wants to be able to load his own images to the background instead of the plain grey that is there now. i've searched and searched, and basically can get this working
BackgroundImage = Image.FromFile("C:UsersMeFileName.png")
i just slapped that onto a button just to get it to work as i was experimenting. but that only works for a file of that name, on my computer, in that folder. what i'm looking to do is get it so a user can browse his own directories for images and upload them as the background on the form. and be able to save the settings as well. but so far i have only seen different ways to load preset images that you can load. if it's even possible? i'd assume that you'd use the openfiledialog command, but i'm not that well versed in vb as of yet.

Although my code compiles, it does not result in a change of the background picture of button1 here is my current code. Is it possible that my condition contains some error? or is the command itself wrong? [code]

Both images are in .gif format and the small image background is transparent.I set the picturebox's backcolor for small image to transparent, but I only get the backcolor of the form in stead of the big image.Is there anyway to see the big image at the transparent area of small image?

I am trying to make a 'puppet' change into a ball when I press e.g. the right arrow key. I used getasynckeystate(keys.right) to check for the key in a timer. The moving is working well but I don't have an idea how I can make it change in a picture of the 'puppet' changing which then changes into a ball. Does someone know how to do this?

I have a picturebox and I have a image with a blue and red square. When I click a button it puts that image into the picturebox as background image. The background image property is set to tile. But when I click on my form to draw the image to it, it just draws the original not the one that has the tile effect from the picturebox. Is there a way i can do this to keep the tile effect?

I have a problem when i opened a picture that
size image < size picture box
How can make the background of the picture box become an image too because my coding was to get the pixel from width and height picture box.. When I found the none image property, vb will show the error.. said coordinate(x,y) was null. It can be illustrated like on the picture above.
Sometimes I will used it when:
picture properties - size mode = center image
So the picture will found at center height and width.. and the background will surround it. Sometimes I used it after rotating the picture.. The problem occur when the picture get rotate for 45 degree. I am taking all point corners of the image and rotating it. So the picture will create 4 triangle at the corners..

Ive been working on creating a side scroller game, and the back color of my pictureboxes needs to go. when transparent, it shows through the program and onto whatever is active in your Windows os(usually Visual studios).
I am trying to rip pixel color off of the background image picturebox( the level), and replace parts of the character picture box that show transparency with the level art. there may be poor logic in my code?
Heres my code:
Dim newImage As Bitmap = New Bitmap(PictureBox1.Image)
Dim backImage As Bitmap = New Bitmap(PictureBox2.Image)
Dim ximg As Bitmap = New Bitmap(PictureBox3.Image)
[code]....
not the best idea, but all i get is one color for all the level pixels placed in the new image, which is odd. any poor logic you see in this code that could allow the newImage.setPixel not to be 1 color? when i breakpoint, it is recieving different colors from the backimage.getpixel, but only putting one shade on for setpixel somehow. im not going for an accurate color read from the background yet, just wondering why im getting 1 pixel color for the whole picturebox background when being changed.

I know strings are immutable, so the minute you change a string reference's value .NET makes a brand new string on the heap. But what if you don't change the value of a string reference; rather, you simply pass it into a function ByVal -- does this operation copy the string value on the heap as well? My inclination is "no," but I'd like to confirm.
For example:
Public Function IsStringHello(ByVal test As String) As Boolean
Return (String.Compare(test, "Hello") = 0)
End Function
Calling program:
Dim myWord as String = "Blah"
Dim matchesHello as Boolean = IsStringHello(myWord)
I know passing myWord by value makes a copy of the reference to "Blah", but since I have not tried to change the string itself, would it make another copy of the string on the heap?

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 sure there are similar threads, but I've search and tried most things and still can't find something that works.
I am testing a small project, in the attempt to find the solution for a much bigger application. So, here's the deal. I'm using VB 2005 and MSSQL 2005 (both are Express editions). I've stored the names to some images in the database.
When I use PictureBox1.image = My.Resources.<filename>
and build the application, it works and properly displays the image. Now, what I'm really trying to do is extract an image names from the database and assign it to a variable, this is what I have.
Dim EqTest As New Test1DataSet.EqTestDataTable
Dim EqTestAdapter As New Test1DataSetTableAdapters.EqTestTableAdapter
EqTestAdapter.Fill(EqTest)
[Code]....
I've used the messagebox for testing so that I can see what the value of "Trythis" is, and the string is "My.Resources.<filename>", which is the correct string, but I can't use that string in the picturebox to display the image, because I get an error "Value of Type String can not be converted to System.Drawing.Image".

My app has scrolling images in the background and a picturebox on top. The image in the picturebox has transparent parts. How can It so that the transparent parts show whatever is belo the picture box, not the form background? I have tried taking screenshots and positioning them as background but this just freezes the app.

I'm trying to make a visual map editor, and figured that a DataGridView would be the best way to go. I would like to make it so that you can click one of many buttons to set which new image the grid cell will be set to when you click it. I've set up pretty much everything except that I can't figure out how to set the background image of the cell that I clicked.

I get how to stretch an image in the picturebox, that's easy. Now how to make sure it keeps that original ratio, so it's not distorted? Maybe it's as simple as a different setting on the picturebox? Maybe I am mistaken and want to use a different tool?
