I want webbrowser1 to navigate to a list of URLs that will be read in from a text file. (I left that part out of the below code and just manually entered urls as examples.) What I have found is that the webbrowser1 will navigate to the urls, but it will not stay long enough to get anything from them. In this example, not even the final page loaded ends up getting saved. Can someone tell me how to halt the attempt to save webbrowser1.documenttext until it is fully loaded?

View 2 RepliesI have webcontrol inside windows application now i want save image inside page on my local hard disk?
I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

First off, I'm using Visual Basic 2010. I've done pretty well with starting out with some basic things. Copying some codes from tutorials to learn what each code does. But lately I've been venturing into possibilities of ideas in my head, and the recent idea is very simple, but I'm not sure how to approach it.
I have a main form that has options to open up other forms. And in one of those other forms, I want to make it so that you can enter text into a textbox, then click a button to "save" the textbox's content so that anytime the program starts, that previously saved content of the textbox will be the same.
And on top of that, I want to relate the textbox back to the code in the main form.
If I didn't explain that well enough, I'm working on making an extremely basic web-browser (a big jump from what I've been doing), and I added the option under a menustrip to open up Form5 to change the home-page.
I have a textbox, and a checkbox next too it. If i type "VB.net Forums" in the textbox and then i click on checkbox I want it too save the value in textbox so next time i open the application it is there.
View 3 RepliesI am attempting to write a playlist for my media player which is already built. I have found a way to build a playlist for it but it would be helpful if I could save the contents of TextBox1 to a text file without using the save as. I am trying to get over a user inputting a file name for the finished text file so is it possible to write the file c: est.txt without using the save as dialog? I have found that I can use a vbs program file which creates a playlist in a folder. I save the vbs file text to the textbox then save it as a vbs file in the playlist directory, then execute the finished file to make the playlist.
