View 1 RepliesI will use the Background Intelligent Transfer Service (BITS) to transfer files from a client (laptop) to a shared folder on a server within our local network.The problem is a very slow network bandwith, if we transfer a file, the other clients can´t work, all requests to other clients (application) or viewing internet pages needs a long time.My idea is to use BITS in my tool to copy/transfer a file from client to server, also I hope to get more performance for the internet requests.

View 4 RepliesI'm writing a small application that downloads some files over ftp, the incoming directory is monitored by FileSystemWatcher_Created, on creation I want to extract some text from the file and call another application with the text as parameters the problem I have is the FileSystemWatcher_Created procedure is triggered before the file has finished downloading, I could download it elsewhere and move into the monitored directory but some of the files may be quite large and Im wondering if there is an efficient way of waiting until the file is ready? along the same lines what is the best way to queue the tasks as there can be many files coming it at one time, I've looked at threading but would that be suitable for such a task as there will still be a bottleneck at the application called by FileSystemWatcher_Created ?
heres an outline of what im doing:
Private Sub FileSystemWatcher1_Created(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Created

View 4 RepliesI'm having trouble getting started with this application I need to do. Here are the details:
Its an application to calculate student grades for a group project. Create a text file to store names of 5 students, line by line. In a separate file enter peer evaluations from 0 to 1.0. Enter these numbers for evaluations:
1.0, 0.8, 0.9, 1.0, 0.6
0.2, 0.9, 0.5, 0.6, 0.7
0.5, 1.0, 1.0, 1.5, 0.9
0.9, 0.9, 0.9, 1.0, 1.0
1.0, 0.9, 1.0, 0.8, 0.9
This means that student 1 gave 1.0 evaluation for himself , 0.8 for student 2, 0.9 for student 3 etc.Student 2 gave 0.2 for student 1, 0.9 for him- herself, 0.5 for student 3 etc. Read these into a 2-dimensional array. If any of the values is greater than 1.0, set them to 1.0. The program should calculate the average evaluation for a student. While doing so, the program should ignore evaluations that student gave to him-herself. Populate a list box with student names when the form loads. The user should enter a project grade (same for everyone) in a textbox. Then the user can select a student from a list and click �Calculate� button. The program should display the project grade for that student by multiplying average evaluation by the grade for the whole group (project grade).
