I need to show a thumbnail of a web page on a VB 2008 form. I have found a number of code snippets that mention something called an IViewObject which can apparently do what I need but the only examples are in C.
View 5 RepliesI am writing a Windows Service to act as an internal Web image collector. I can thumbnail Web navigated to webpages using a webBrowser Control. But since a Service will not support a UI based Control like a WebBrowser control I have switched gears using the wrapper WebClient from system.net. So I am looking for a way to capture and thumbnail a Webpage.I can use the following to grab images off a web pager using webClient but cannot figure out how to thumbnail the entire page.
Dim imgBuffer() As Byte Using wclient As New WebClient() imgBuffer = wclient.DownloadData("http:// Webpage/Image") End Using
Using mem As New IO.MemoryStream(imgBuffer) Using img As Image = Image.FromStream(mem) Me.PictureBox1.Image = img.GetThumbnailImage(100, 100, Nothing, IntPtr.Zero) End Using End Using
End Sub
I need to display the webpage in webbrowser but which it fit the webbrowser there is no need to scroll it and it shows as thumbnail.
View 2 RepliesI have a problem I am trying to solve in an elegant manner. I have a .net application that I have created. I am trying to get one of the forms to be shown from a webpage. This sounds strange I'll admit, so here is the backstory
We have some large monitors at work, that show information on them. I have no control over how the information is displayed. Currently they are just using a browser and tabbing in the browser to show each different piece of information on the screen. Most of the info they show is just standard html stuff, text and images.
Now along comes my winforms application. The part of the application I need to show is a graphical display. Everything on this display is drawn using GDI+, if that matters. I need to get this form into a format that I can show. Below is my own solution, but I am pretty sure this is not the best method, but it may be the only method I can use[code]...
I though about doing something with the clients, however the clients are not always up, so I could have periods where the image wouldnt be updated.
I also was thinking about an ASP.net solution, but that would require me to learn ASP.net, and I am not quite ready to take that challenge
Is there a way to show videofiles' thumnails in VB application? Ideal situation would be so that the application would recieve videofiles via drag and drop and then show thumbnails from them the same way as you can see a preview thumbnails in Windows file-explorer.

View 2 RepliesI'm working on a vb.net web application and want to make it to where when someone puts in a url into the browser or when someone clicks on a shortcut, a new browser window is opened but there is no back or forward, no refresh, no navigation bar, etc. Does anyone know how to do this or if it's even possible? I just want the browser shell essentially.

I have some code that allows the user to browse for an image and then when that image is opened, it is copied to a new directory. This all works fine, but I would like to know if there is a way to create a thumbnail of this image and save it into a subdirectory inside the directory where the original image has already been copied?

Is there a .Net control I can use to display a web page from a vb.Net windows forms application?
I am writing an app that will produce a slide show from a specified directory. The idea is it will ideally include Images, Video clips (via Windows Media), URL's (held in a text file), PDF documents and power point presentations.
Images and media clips aren't an issue. At present I am looking at displaying specified web pages. I am aware that I can use
System.Diagnostics.Process.Start("http://webinta/Pages/Home.htm"
to open a browser window, but I want control of that as after a specified amount of time it needs to close so I can display the next image (media clip, url etc).
why I need to instantiate a form instead of form.show?

I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
I am creating a simple researcher application to access and store data. As of today it workes by entering a number into a text field and hit enter/button. The result then shows up in a non-menu webbrowser window. What i would like it to do was to exclude the web browser window, and instead show in a popup window inside the application. This should be rather easy, here's what i think might be a problem. I want only to show specific lines from the webpage, not the whole page.

View 6 RepliesMy mate & Myself are currently building a IRC Client, a problem we have come across is when opening a chatroom the form Freezes for example.
We are currently using arrays so we can open multiple chat rooms and at this current time to open a chat room we use
Channels(ChatIndex).Show()
The form opens but freezes.
I have also tried using
Channels(ChatIndex).ShowDialog()
Application.DoEvents()
Using the above code, the form does not freeze but appears we can not access any of the controls such as (RTB)
What would be causing the form to freeze on .show(), Has anyone else had any similar issues?
