View 2 RepliesI am wondering how to save a textbox contents to disk?? Using the MSDN help I was able to come up with this code so far. I have a menu strip item labled "save as." when I click it the prompt to allow you to pick a location to save comes up and it will save a text file to the selected location but the .txt file is blank. How do I set this code so that it knows to save the contents of the textbox.

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 1 RepliesI have a mySQL table(IMP_SCANS) holding the file, it's name and size for every document:
scan_1 blob
description varchar
filesize int
doc_no varchar
doc_date date
I managed to insert a file to the table. Now I need to save the file to disk.
So I have the code:
Dim conn As New MySqlConnection
Dim cmd As New MySqlCommand
Dim myData As MySqlDataReader
Dim SQL As String
Dim FileSize As UInt32
Dim fs As FileStream
[CODE]............
I all works fine up to the line: myData.GetBytes(myData.GetOrdinal("scan_1"), 0, rawData, 0, filesize) Where it says "Object reference not set to an instance of an object". I cannot figure out why I receive this error.

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?

I want to develop an application which can Write, Save, Read text files(or html files) What I want the application to do is. When I open my application I can write stuffs and then it will save it to my hosting/server. Then, the application will read the text which I already save.. So far, I can only make the application read it by using WebBrowser control and navigating it to a specified URL. Example: [URL](or message.txt) Which I modified from the website not from the application. I want to modify the text or html files from my application.
