View 8 RepliesI 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?
View 1 RepliesI have a program that works I would just like it to be able to find the file with out me specifying the actual path. Because if it is on someone's computer other than mine the path might not be correct and it will not function properly. Here is the code I have done. The file it is looking for is of course names.txt. I have not been able to find much info on this.

This 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?
I've been searching for hours tonight searching existing posts, other websites and all i can find are examples of how to capture a image from a webcam.Does anyone have any code that simple talks to the camera device via WIA, and then saves every image found on the device to a hard drive?I found this code below. Credit i cant tell you as i have a bunch of different flavors of code, but this only saves the file as a tmp file, and not the actual image file i expected after selecting?

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 1 RepliesIs it possible to load HTML content into the HTMLDocument object without having to use the WebBrowser control? I have an html file stored locally that I want to parse in order to find out which checkboxes are on and which are off.

I am looking for a way to retrieve the temperature of hard drives in VB Express 2008. I have found posts at a few different places that accomplish this with the following: Public Function GetDriveTemp() As Integer
Try
Dim searcher As New ManagementObjectSearcher("rootWMI", "SELECT * FROM MSStorageDriver_ATAPISmartData")
For Each queryObj As ManagementObject In searcher.Get()
Dim arrVendorSpecific As Byte() = queryObj("VendorSpecific")
GetDriveTemp = arrVendorSpecific(115

This function retrieves the temperature for all the hard drives in my system (excluding USB), two internal and one external esata drive. There are two problems, tough: 1. I want to know the drive letter and maybe the drive label that the retrieved temperature corresponds to. I'm assuming that the * in the query, "SELECT * FROM MSStorageDriver_ATAPISmartData", can be changed to specify a particular drive rather than all drives, but I don't know how retrieve a list of all the drives in my system or how to write the query based on those results.
2. If I call the funciton from a some click event like for a label or button, there are no problems and the return value seems valid. But when I call the function from a Timer_Tick event, the mouse cursor is the busy cursor as long as the mouse is within the form, the form doesn't receive any click events, and it cannot be closed.
I know what I'm trying to do can be done because there are a few utilities that provide this information.
how to retrieve the temperature of a hard drive in Visual Basic 2005? The temperature can be retrieved from the S.M.A.R.T information, but I don't know how to do that in Visual Basic 2005. There probably is a way, but unfortunately, I don't know.

I've been checking endlessly on MSDN and the net in general trying to find out how to get the computer's "C:" drive serial number and also the GUID.Everything I've found seems to pointing to the System.Management library using the ManagementObject, but "ManagementObject" doesn't appear to be recognized by the IDE?!I've imported: System.Management, System.Management.Instrumentation, Microsoft.Win32 and System.IO, but ManagementObject is still coming up as an error.I'm aware I can simply access the registry to get the GUID, but can anyone simply give me the code to access these 2 elements please.
