VS 2008 Getting An Image From A Webpage, Insert Into Picturebox
Aug 29, 2009
I'm making a registration form for a website. However, there is a capatcha. I need to get this image and put it into a picturebox. I had a method to do it but since its a capatcha it's dynamic and I can't save the image. How would I do this? i tried this:
I am creating a small movie application using MS VB .Net. On my form I have a two TextBoxes, ComboBox, a Button, and a PictureBox. What I would like to do is when the MovieID TextBox equals "10" (or any other number), I click the button and the corresponding Images number will be inserted into the PictureBox. For example: C:\Images is where all my Images are stored. When the MovieID Textbox = "10", the Picturebox will be populated by the Image name "10", when the button is clicked. If the MovieID Textbox = "23", then the PictureBox will be populated by the Image name "23".
How can I insert text into a PictureBox in VB 2008. I would like to add text to graphs which I have been able to generate, but I cannot find the equivalent method to use with text,
I need to scan a webpage to see whether or not there is an image on the webpage. I have the id of the image which is "apples", and I want the program to search the webpage for the image, and if it is not found, to go onto the next thing (which would be to start timer2).
how i could get an image URL on a web page in VB.Net?For example: The user would navigate to [URL] and the google image URL would be stored in a string?
I found this code on another site for saving the webpage in the webbrowser to an image. I browse to a website and call this and works great. Then when I do it again, I get an empty image but the size of the webpage. It always works the first time but no more after that.
Here is the Private Sub GetImage() If WebBrowser1.Document Is Nothing Then Return End If Try Dim W1 As Integer [Code] .....
I have application, where is a big image, displayed in picture box, but only a part of image is on the screen (I set display mode "zoom", so it's center). But now, I need to fluently scroll this image using mouse, so when I click on picture box, and move mouse, the visible part of image should be changing.
I have made a program that has an image moving across the screen. The image changes its movement direction when the arrows are pressed. Now, I am trying to rotate the image (an arrow) to match the direction. Here is the subroutine to rotate the image. It uses the hidden PictureBox2's image (the original right arrow) as the source, because I couldn't think of any other way.
were currently developing a software for our thesis. And were having a problem with the SAVE button. this SAVE button will save the two individual picturebox into one .BMP image when saved.
I have done a lot of googling and tested a few snippets of code i can't seem to get this, all i want to do is show an image in my picturebox1 that is from the web instead of on my harddrive, i thought:
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.
I have put folders in my resources folder and I am trying to load the pictures when the user presses the right arrow key. The code I am using is: picCharacter.Image = Image.FromFile("ResourcesRight MovementRight-01.png") What do I put in front of the "Resources.." that would make it load it from the projects folder?
I need to know how to draw a bitmap image into a certain area in a picturebox, I also need it to be a specific size. I remember seeing it on the internet somewhere, I just can't find it again.
I have a contextmenustrip with 10 options on it. Each option calls an image from my resources and changes the background image of my form. When i select an option how do i save it and make sure thats the image that loads next time i run my application ?
How come this doesn't work when I try to press a button to save a picturebox to a file?
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click PictureBox1.Image.Save("C:Test.png", System.Drawing.Imaging.ImageFormat.Png)
I have a picturebox and I am trying to create a masking system to use in different graphics projects.Is there a simple way to select an object with pixel precision. For example if I have a picture of an animal, how can I select it by moving the mouse over it with precision instead of selecting an entire rectangle area where the object might be transparent?
Is there a way to do this with the builtin capabilities of gdi+ or is this something that requires code? If it does require code, does anyone have an example of this?
How do i select a picture that is in my resources for my picturebox in vb code? Depending on a selection i have made on the form a different picture has to be placed in the picturebox.
I am trying to insert images in a field dbo.Temp.Tmp_Image of the Temp table. When I run the code i get this error "INVALID COLUMN NAME='LODMK120' in LINE cmd.ExecuteNonQuery()... i dont understand why it says LODMK120 ???? But the tmp_kwd has value = '176-83-LODMK120' and not 'LODMK120'. I dont understand why it cuts the '176-83'
Example data for Tmp_Kwd (which product code) Tmp_Kwd:176-83-LODMK120 Tmp_Kwd:176-83-LODMK260 Tmp_Kwd:176-83-LODMK320
I have a form containing a listbox showing a list of image names. It's bound to the database table. When an image name is clicked it shows the image and imagename in a picturebox and textbox respectively. When no image is selected in the listbox, a new record can be inserted by browsing a new image in the picturebox by an openfiledialog, writing the imagename in the textbox and pressing the OK button. When an image is already selected, the record can be updated by pressing the same OK button. The data is saved into MSSQL Server 2005. Corresponding table fields are Keycode int autono, logoname nvarchar(50), logo image.Now the problem, when I insert a new data with an image everything goes fine but whenever I try to update an existing data with an image it throws an exception- 'A generic error occurred in GDI+.' at the following line- 'pic.Image.Save(ms, pic.Image.RawFormat)'. Surprisingly when I update an existing data without any image in the picturebox no exception is generated. I have crossed checked it and seems that the problem is just at one point- 'Updating the image from the picturebox'. My code to insert/update the data by OK button and to populate it by listbox doubleclick follows:
Code: Private ms As MemoryStream Private arrImage() As Byte Private conn As SqlConnection

In my project I am using a camera to capture images. The images will be stored in a byte array. Now I want to display my images in byte array to picture box on my form. I am pasting the code bit below.
HTML Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (ByRef Destination As Byte, ByRef Source As Byte, ByVal Length As Integer) Delegate Sub MyFrameHookerDelegate(ByVal FrameType As Integer, ByVal row As Integer, ByVal Column As Integer, ByRef lpImageAttribute As TIMAGEATTACHDATA, ByRef Buffer As Byte) Public ImageBuf() As Byte [Code] ....
I want to display the image from ImageBuf() to a picture box on my form.
