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

View 2 RepliesI wanna send POST data to the current web page viewed in my webbrowser. It's for logging into a page so the fields are "Username" and "Password". And then I might have to make it press the "Log in" button?
EDIT: It was easier than I thought when you don't need to do it silent in the background.
PHP
WebBrowser1.Document.GetElementById("username").SetAttribute("Value", txtPassword.Text)WebBrowser1.Document.GetElementById("password").SetAttribute("Value", txtPassword.Text)
Now I just need to figure out how to press the submit button
I'm having a problem getting the src of the image the mouse is hovering over in a webbrowser. I can get an href just fine, just not an src. To get the href, I used this
Something = Webbrowser1.Document.ActiveElement.GetAttribute("href")

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).

View 2 RepliesI'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:
pic = Form1.WebBrowser1.Document.GetElementById("ctl00_MainContent_CreateLiveId_ctl00_HIPControl_Image")
PictureBox1.Image = pic
But I can't convert "System.Windows.Forms.HtmlElement" to "System.Drawing.Image".
How would I go about doing this?

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

I get "a generic error occurred in GDI+" raised. Googling reveals a few hits for this problem but seemingly mostly related to using databases rather than the file system.
Has anyone come across this? I don't want to paste all my code here in case my nemesis is watching, however basically I'm getting a reference to the PictureBox's Image property and manipulating the pixels using GetPixel and SetPixel, and then setting the picturebox's image property = my modified bitmap.
I understand that the error is generally related to the bitmap not being ready to be saved - is there anything specific I need to do to "close" the bitmap so it can be saved?The strange thing is that I'm sure this was working earlier today and now seems to have arbitrarily stopped working.
I have looked around and cannot find a way to download an image from a webbrowser without reloading the image or webbrowser AKA using the cached image.

I've pulled down a webpage using a WebRequest object, and need to parse it, but first I need to render it since there is scripting on the page. I don't want to use the WebBrowser control because that forces me to jump out of my current function to the DocumentCompleted event, and "lose my place" (so to speak). Is there any way for me to pull down a URL using a WebRequest object and have the page rendered but still stay in my function?
