Write An Application That Uses More Than One Thuread?
Mar 4, 2012
I am currently trying to write an application that uses more than one thuread, but I have little experience of this and the more I read about it, the more confusing it is.I currently have one main prog (StartupForm) that has 3 items defined as tool Strip items io the menu. Upon selecting each item, it runs the relevant Click subroutine.
What I am trying to do is within each subroutine, getting it to launch a additional form (option1Form, Option2Form & Option3Form all running under running under ew threads and independent from the original programme. Hence when the original programme is busy, the sub forms are running their own code quite happily. The only interaction I require is that the Main Programme (startupForm) Updates an array. Which the the new thread / form can read. Can this be doe some how Byref

I bet someone already asked this but i cant seem to find it. Ok i need is a global settings that can be updated which will affect all users. I was using xml files in the program filestill now and I need to get around using this because the files can be delete or over written incorrectly. I started using the settings option and realized application level is read only and i cannot use user scope because then it wont be global settings. Is there an alternative to this.

I understand that I cannot use the System.Console to output information from a Windows Forms application because the standard input, output, and error streams are not run through the console in winforms apps. But I can't seem to find any documentation on where the standard input, output, and error streams are being directed to! Basically, I have a winforms app that accepts command line arguments and can be run in batch mode, however, I just want to direct some feedback to the user based on whatever method they're accessing the program. The app is used to redirect a client-server application from one server to another. In some instances, the user does it by hand (with a mouse), and other times they're doing it in batch mode (using SAS, command shell, VBScript, etc...). In those instances, I'd prefer NOT to use MessageBoxes because it will kill any processing they're doing.

I am proficient in Visual Basic, but I think I need to use .net and move with the times to achieve what I want.I am trying to write an application which extracts text from documents (.doc, .pdf, .xls etc. etc) using IFilter.I have found a very good example application in C# (Using IFilter in C# - CodeProject) which does what I want, but I am really struggling with C#.Does anybody know if there is a way to achieve the same results (i.e. extracting text from documents using IFilter) in VB?I have found a few examples on the web which do not seem to explain much - most examples I see are in C#.

I needed to make an application that calculates weekly pay of employees at an hourly rate. The overtime schema is that: hours less than or equal to cutoff1 are paid regular rate. hours over cutoff1 but not exceeding cutoff2 are paid 1.5 times regular rate. hours over cutoff2 are paid double time or 2 times regular rate. [Code] The employee must choose Category A, B or C depending on the amount they have worked. I am completly new to visual basic, I am not sure how to continue with my if and then statements. I must also create the application with 3 radio buttons, where the user clicks either Category a b or c and then buttons which say calculate and clear. [Code]

I am trying to write an application that monitors internet usage. So it sort of needs to act like a firewall/proxy, recording each site the computer goes to. It will record all these sites in a log file. Using a proxy server on the network is not an option, each computer running this software needs to be self sufficient. Do you have any suggestions on what to use for this project?

how to re-write my application (http:[url]....) to be multi-threaded using the background worker. The use case is something like:
1. User opens a binary file, it can be several Gbytes in size so reading it into memory isn't practical.
2. User can then navigate through the file in 188byte chunks, data is read from disk, decoded, and displayed for each chunk in turn.
3. User may want to search for some data or build a report. This will involve repeating the read, decode, display, function multiple times. During this looping the GUI stops responding and there is no option to cancel so I want to make it multi-threaded. So, is it safe to open the file in the GUI thread and then read from the file in the background thread? I currently use something like this to open the file once:
Dim fi As New FileInfo(filepath)
fs = fi.OpenRead()
and then in a separate sub multiple calls to:[code]..........

I have a form in VS2010, written in VB, and it has a subroutine calling for information out on the web using an httpwebrequest object. It takes a while for the response, and I would like the subroutine to write a message to the form (into a Label) for the user to see while waiting for the application to respond.
I tried writing the message with a Backgroundworker and then as a second thread. I got it to write the message, but it always seems to wait for the http response before writing the text. How do I write the text immediately, while waiting for the data?
