I have a program that must copy a file to 3 locations, the local hard disk, a USB drive, and a network location. I have the file (about 70mb) loaded into a byte array. My quesion is, since I'm not actively modifying the byte array, can I impliment a form of multithreading where all 3 threads read the same byte array at the same time?

How can I search the local disk for a file type and copy the full path to a new location. I am trying to write a backup program that will copy all pst files to the server while maitaining the structure, so if there is a pst located in "C:pstuserpersonal1.pst" it would create the folder "\serverpstuserpersonal1.pst" and copy the file to the correct location. I would need it to do this for each pst on the hard drive no matter the location. The user running the program will not have admin rights, so it will need to skip files it cannot access.
View 13 RepliesI'm creating a WPF application in VB.NET with the 3.5 Framework. (If you provide an example in C#, that's perfectly fine.)
In my project I have a Template for an MS Access database. My desired behavior is that when the users clicks File-->New, they can create a new copy of this template, give it a filename, and save it to their local directory.
The database already has the tables and some starting data needed to interface with my application (a user-friendly data editor)
I'm thinking the approach is to include this "template.accdb" file as a resource in the project, and write it to a file somehow at runtime?
I found something very strange, in the data base explorer I modify the conection to the location of the data base(F:My DocumentsMy ResepteResepte.sdf) , but after raning the app. the path is back to what it was in the project folder and so the same in the selution window. It is set to Do Not Copy. How can I change this so that the IDE looks at the propper data all the time.

My Dad made an application which had a feature that i want, basically his programme reads the users hard drive serial number and then multiplies it by say 12 and then divides it by 7 for example. This number is then shown as a 'Authorisation Code' which the user has to email to him and then his breaks it back down to the original hard drive serial number which he sends back which is the application serial number to activate it. I want to know how to read the actual hard drive serial number or a number that every computer has so i can do the same but i have searched everywhere and cannot find any examples for VB 2008 apart from one which didn't work

View 3 RepliesI 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?

How do I load or display an Excel file located on the hard drive in vb 2005?
View 2 RepliesThis is my first attempt at creating a Winforms application, and I have been developing in the .Net Framework (Silverlight, ASP.Net, WPF) for about 6 months. So, my appologies if this is a newbie question.
Basically what I am doing right now is taking the drawings of a stylus-based input, and storing them into an image field in a SQL Server database. Then, in another form, I go and get that image out of the database, and load it into a picture box. It works, but it is rather "sloppy" how it got there.When the user clicks save, it stores that image into a temporary folder, then converts it to a byte array and throws it into the database that way. Then, it deletes the file from the temporary folder. When retrieving it, it pulls it out of the database in a byte array, then converts it to an image in a temporary folder, thus displaying it on the form.
Is there a way that I can just bypass the storing of the file onto the user's harddrive both times, and go from byte array to picturebox?

The drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.

View 12 RepliesI'm sort of new to the vb 2008, and I would like to be able to send a file to another computer and save it on the local drive. Doesn't have to be in any certain folder, but just on the c drive. I know for the old visual basic you would use winsock for this, but in 2008, they have removed it. What and how will I do this. There will be no program on the user's computer. This is done all from one computer sending to another with no program listening on it. This computer is on my network with network sharing, so I can just do like a \computernameorIPaddress and open send the file that way.
