I think this might be related to threading (which I havent really worked with)..
In this app I'm developing, I am downloading a file when a user clicks a button. However, since the file is 20mb or so, its kinda unfortunate that the application hangs while doing it...
Do I have to go into multithreading here, or is there a simpler solution? (Or maybe multi-threading is simple?)
I have an application that opens a bunch of Excel files in the background and saves them as pdf files (amoung other functions) and when accessing these Excel files on a shared drive I get a lot of quick pop ups that look like they say "Downloading..." something or other (to hard to get a screenshot) they also have a progress bar. I was wondring if there was a way for me to stop them from displaying.

View 1 RepliesI have a windows form which to summarize lets the user open a file containing 32 bit hashes, then search for one of them. The hash is then converted to its string representation. The application is giving the results I would expect but I'd like to make it execute faster than it does now; some files can be pretty big > 100 MB.
I'm doing the file read using a BackgroundWorker object to display progress updates and ensure that the UI is available during the process. But for that i need to add a System.Threading.Sleep(1) instruction in the loop; otherwise the application freezes with big files. And System.Threading.Sleep(1) creates a noticeable lag. Any suggestions on how to make searches fast without freezing the UI? Getting speeds comparable to hex editor programs for example.

I want to download thousands of files from the web and save them locally. What is the most efficient way? It is important the failures timeout within 10 seconds.
Is there a better way to stream one stream into another? Maybe a smaller buffer, like 1024 bytes at a time, is more efficient for large files?

View 2 Repliesget the whole and same content of any file i uploaded, for my editing purposes in my editor w/c retrieves file from the database. i.e of files are ".doc and .txt"and by the way what i meant by same content is the whole same appearance of my .doc or .txt file i.e "if the text is bold, forecolor is red and etc.."

View 1 RepliesUsing the Microsoft VB 2008 Express program, I'm making a SWd20 character sheet (D&D) to be distributed to a few friends. It's a program where the user can figure out stats, species, class, etc without having to make any calculations him/herself.. but this will all be in vain without saving it..
So I'd love to know how I could make it so the user can save and load the entire file(including buttons, labels, text boxes, menu strips, possibly multiple forms, etc) on his/her own computer.. Is this possible, and if so, how can I go about this?
I've already searched through and found lots on saving text in the files to .txt files, but that doesn't cover everything I need

View 5 RepliesI'm having an issue with the streamreader. I had it working but I've changed something and it has stopped.
I have it in a Do While loop reading line by line, but it doesn't finish reading. It reads about 27 lines out of 4000, then stops.
I changed the contents of the file it was reading, but it's still just save as a txt notepad file.
I also changed how I tell it which file to open (UserSelection.T2) however it does open the file just doesn't finish reading it.
Doesn't kick back any errors, it just doesn't read the entire file.

View 1 RepliesHere is the thing, I have a rather bit datagridview on a form and, I would like to print that to a bitmap.
I've tried something like this:
VS2010
Public Sub SaveToImage()
Dim SFD As New SaveFileDialog

PS: I have modded a little bit this datagridview so it looks like a gantt chart with collapsible rows, and variable & multiple timelines at the same time, so the bars might go a long way to the right of the screen, that the main reason for the save to bitmap.
I already know the basic procedure of how to read specific cells of an .xls file using VB.NET but I can't figure out how to automatically get all the data from such a file.Basically, I'm obtaining the data like this:
Dim xlApp As Excel.Application
Dim wb As Workbook
Dim ws As Worksheet
xlApp = New Excel.Application
[code]....
In this case, I know that there will be content in the first 10 rows of the columns A, B and C but what would I have to do if I had a huge document whose size and content might even change from time to time? I know that there is also an attribute ws.rows.count but this always returns a big value like 60000 even if only a few rows are occupied.So basically, I'm looking for a simple way to loop through all the used rows of an Excel file with the possibility of accessing each cell in that row.
