Loading An Image Into The PictureBox From A String Variable
Nov 2, 2009
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".
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]...
Is it possible to load an image into a picturebox when that picture box is clicked? What would the syntax look like? It's an image that I already dropped onto the form that I would like to load into that picturebox.
I want to make a program similar to this one: [URL]. I already have the ListBox ready. But how do I load the images? The image name works like this: -File1.package -File1A.jpg -File1B.jpg So the .package is removed and A.jpg or B.jpg is added.
I am trying to get a picture box (that has a loading image .gif) to be visible while the program reads a text file and change visible to false when all the information in the file.txt is displayed in the textbox.
Here is my Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click PictureBox1.Visible = True If System.IO.File.Exists("C: est.txt") = True Then Dim objreader As New System.IO.StreamReader("C: est.txt") [Code] .....
I currently have 4 images that I need to load into a picture box at different times, it works fine for me but if I send it to a friend it wont work because the file path is different. I use this at the moment:
If filmType = "Jumper" Then img = "E:TheatreBookinginimages" picFilms.Load(img) lblFilmInfo.Text = ("A genetic anomaly allows a young man to teleport himself anywhere.") lblFilmInfoTwo.Text = ("This gift leads him into a war that has existed for centuries.") End If
I have a picture box on my form along with a combo box with a number of different options. So anyway when a combo box item is selected I want it to look in the dataset for the selected item's row and pick out the image to load and then using an IF statement it sets the image (or should).
Dim RaceImg As String = DS.Tables("tblRaces").Rows(ID).Item("RaceImg") If RaceImg = "AusGP" Then GP_Picture.Image = Image.FromFile("./Track Images/AusGP.png") ElseIf RaceImg = "MalGP" Then GP_Picture.Image = Image.FromFile("./Track Images/MalGP.png") End If
I have tried a number of different ways to get this working, I have tried them in the resources for the program and also tried the following code GP_Picture.Image = "./Track Images/AusGP.png" It seems like the picture box isn't redrawing or something? Just to add it will load the first image which is the AusGP because thats the first option in the combo box, after that none of the others will load.
Just want to know the best method to load a picture in a picture box dynamically. As part of my development, I was supposed to load 4 pictures from network to 4 picturebox controls.
For which, I found, 2 methods. 1. Picturebox1.Image=new bitmap("C:\test.jpg") (or) 2. Piturebox1.ImageLocation="C:\test.jpg" Which one is more suitable interms of performance.
In my user control you can load an image into a Bitmap type, it then displays the image onto the usercontrol. However, it works fine with .gif format images, but when i use .png it seems to make the image bigger than what it is.
Private imgPicture As Bitmap Public Property Picture As Bitmap Get
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 window application develpoed in vs 2008, framework 3.5, in which i have put a button.. Now where i click that button the other text boxes are filled up with the data from database thru web service.. what i want is while all text boxes are being filled i want to show an animated loading gif image till data loading is completed in all the text boxes.. i have tried to use image picture box but while data is loading gif image is displyes but in static mode.. cant see animation... i think this is because data loading and animation both are done thru one UI thread..
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.
Ive been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.
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'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.
Is it possible to load an *.ico file onto a PictureBox ? I know I can use : PictureBox1.Image = System.Drawing.Image.FromFile("C:MyImage.jpg") but I'd like to use an icon . I have tried some other methods that read "Icon" , but I failed . Up to now the only thing I have thought is converting the file format form *.ico to *.jpg , but I think that's ridiculous ...
I have a picture box on SSRS. I want to load a picture to it, for exam from D:\Pictures\TV1.jpg (actually user will decide it by using OpenFileDialog)I have set the Source to external and in Value expression I tired
="D:\Pictures\TV1.jpg" and Also ="/<d:\pictures>\TV1.jpg"
but my picture box shows error picture in both cases.
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 know this is probally a really simple question but i have looked through my book and all my notes and googeled and couldn't find a answer that suites my needs.baisicly i have a combobox that gets loaded on form_load, what i want to do is load the appropriate picture into a picturebox when someone selects a item from the combobox. what i cant figure out is how to get the picture into the combobox using code. all the images are saved in my debug folder for the program. picturebox.image = picture.png this is what i asumed it would be but have tried with parenthises, quotes and both and it dosent work.
I have on a simple VB form:Label1Picturebox1FilesysytemwatcherThe watcher watches the camera but only the first picture load after that it gets an exeption and the program stops. I like to continu see what I shoot, but don't want to push buttons on the laptop after each shot. That reason the the watcher is placed. The time between shoot is enough for thw display being completed. The code:
Private MyImage As Bitmap Private Sub FileSystemWatcher1_Created(ByVal sender As System.Object, ByVal e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Created
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 want to load images into a picturebox, save them into a database and display them again in the picturebox. This is the code I'm actually having problem with:
Private Connection As String = _ "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:UsersclientDocumentsVisual Studio 2008ProjectsSavingsLoansCalc.mdb" rivate Sub UploadButton_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles UploadButton.Click [Code] .....
I'm getting this error message: "Type 'Connection' is not declared" On this line: oConn = New OleDb.OleDbConnection( _ New Connection().getConnectionString)
I have a 4 pictureboxes for a database I made but having a problem with loading images in to the picturebox. On my form I have a picturebox, 1 button, 1 textbox, and 1 openfiledialog.
My button click event code Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click OpenFileDialog1.ShowDialog() TextBox1.Text = OpenFileDialog1.FileName Pic1PictureBox.Image = Image.FromFile(TextBox1.Text) End Sub
I can add pics but if I don't select any image (just close the dialogbox) I get an error and not sure what to do ..or what to add. Is there any code to tell it to just close..
