Would it be possible to basically make a full web page appear in a windows form application as an image? Sort of like a print screen command, but just for the web page itself. I need this to show any web page in overview as a image in my program, but I have no idea how to go about this. I suppose it would be almost like a web browser; other then that you can't click links or interact with the page at all, as it is an image. Preferably without loading the web page then converting it, but having it as in image as you load any given page - not sure if it's possible with just VB. Even a rudimentary method would be much appreciated.Note: I'm not to great with VB, so if you don't mind, please provide as much detail as you can with any given code,
I have created a PNG image that is 200 DPI, and perfectly sized for a landscape A4 page size. I needed to convert this to a PDF document, so I've used the iTextSharp library with the code below.This all works, however the image quality has degraded.
Public Sub ConvertPNGtoPDF(ByVal inputFile As String, ByVal outputFile As String) Using fs As New FileStream(outputFile, FileMode.Create, FileAccess.ReadWrite, FileShare.None) Dim document As New Document(PageSize.A4.Rotate, 0, 0, 0, 0)
In the program that I am creating I need to scan/search a webpage for a image. I have the ID of the image which is "dog", and I need to scan the webpage to see if the image is on the page. If it is not then I will start timer2, but if it is then I will pop up a message box saying that it was found.
Here is the code I have so far:
Dim Dog As String = WebBrowser1.document.GetElementById("dog").GetAttribute("src") If dog = Nothing Then Timer2.Start()
I m comparing two images in VB.Net..I get the code in C# & dat code is working 100 % Correctly..Now want to convert dat code to vb.net..& i need help in just converting two lines-
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'm using a WebBrowser control in VB.Net to load a website. At that point, the WebBrowser.Document.Images property returns a collection of HtmlElement that are considered images.
What I'm trying to do at this point, is take a particular HtmlElement that represents an image and turn it into a System.Drawing.Image so that I can manipulate it. But I can't figure out how.
I did try to search for an answer, but came up with nothing. 'WebBrowser', as it turns out, seems to be a really popular keyword.
EDIT: It's been suggested that I use the SRC attribute of the HtmlElement to download the image; but the image can be dynamic - meaning the image I download can be separate from the image on the website....so, that won't work for my purposes.
I found an old article of an example of what I am trying to do (retrieve an image stored in a ms access Db and display on my aspx page). Does anyone have a good example of this for vb.net?
I am working on a personal vb.net project that will allow me to capture a full-sized image of a given web page. I've been working on this for a few of days and have not found a method that is 100% reliable. Here's what i have tried so far...
METHOD #1 - Using WebBrowser Control and CopyFromScreen Problem: Fails to capture the entire content of the page if part of it is off screen, obscured, or requires scrolling.
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'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'm Currently using the following code to open up a folder containing Text and Bitmap files only and store them in arrays.
Dim d As New System.IO.DirectoryInfo("C:Documents and Settings" & GetUserName() & "My DocumentsWolfRiderGamesWaterGameMaps") Dim FileCount As Integer = d.GetFiles.GetUpperBound(0) + 1
[Code]....
What I need is an extra bit at the end that takes the first bitmap file found and puts it in a picturebox called "PicCenter".
I need to have this done through converting its filepath to the image itself.
I will also Need an explaination of how you did it (If its complicated) because i'll need to do it again later.

I need to make a super simple web-page monitoring tool in VB.Net that checks FieldNation.com every few minutes for new work orders. To do that, I need to log in to their page. I think I can figure out how to read the page once I'm logged in, but how can I actually log in? I heard it had something to do with WebClient.
I am developing an intranet site using VB.net 2005. I have a list of reports and their URL's located in a table. The list is displayed to the user using a Gridview control with select turned on. when the user selects one , the selected index changed event triggers looking up the URL from the table and stores it in a session variable. the problem i have is that i now need to open a new web browser window and display the page.
I tried using the envDTE.ItemOperations.Navigate but all of the information provided for this process is written in VB6 and VB2003. In 2005 the DTE proces is not native and when you assigned the ENVDTE.Itemoperatiosn to a shared variable (or any type) and then try to navigate you get the following error: Object reference not set to an instance of an object.
so i tried to create an instance but when i try:
ItemOp = DTE.ItemOperations or ItemOp = EnvDTE.ItemOperations
it gives me an error indicating that this is not possible. My quesion is, does anyone have the correct syntax for using the envDTE.ItemOperations.Navigate instruction from Visual Basic.Net 2005? None of the microsoft pages or microsoft books provide correct syntax. Or does anyone have any substitute code that can navigate a user from a protected sub in one page to a new web page?
In a form I have an ImageList named MainLogoImageList containing a 100x100 pixel 32-bit colordepth image. That is my app logo.
I am too lazy to set up an icon editor and edit an icon of that logo, or convert the image to an .ICO file. (Ergh, well, I am not allowed to install custom utilities.)
To set my forms' icon, I use
Icon = IconFromImage(MainLogoImageList.Images(0))
in the OnLoad event handler to set the window icon.
In my about box, i have a PictureBox with no image. In its OnLoad event, I use
So far, so good, the icon looks pretty good for a being created from a 100x100 pixel bitmap.
Is there an easy "no utility required" :-) way to get the icon that is returned my IconFromImage saved into an .ICO file so that it will keep the color depth when loaded as the app icon? I want to use exactly the icon that IconFromImage creates.
Saving it using
Dim S As New FileStream("MyAppIcon.ico", FileMode.Append, FileAccess.Write, FileShare.Write) Icon.Save(S) S.Close()
in the main form's OnLoad event handler and loading that .ICO file as the app icon in VS's project properties dialog yields and icon that is obviously converted to 16 colors, and looks awful.
I need a code that will load text, the correct image to match it and the command for each image. what i want to do is make a program that will download a swf and an image into to folders. then at startup the program will load all the swf and images and put the images into a listview so when you click on the image for the swf file it will give the link to the swf so it can be loaded.
I hoping to find a current and simple way to do this. I'm using VWD Express 2008 and SQL Express 2008.I'm able to get the client's path to the image file using an asp:FileUpload control on the web form.
How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?

The example is in C# so i converted it using a C# to VB.NET converter and fixed a few of the conversion bugs. The code executes but fails on the line 'Throw New AviException("error for AVIFileOpen")' saying 'AVI exception unhandled'.
