I would like to check the free space of a server share (\servershare) Is this a simple task and how would I do it?I found the following for a mapped drive, but it does not seem to like server names.
Dim cdrive As System.IO.DriveInfo
cdrive = My.Computer.FileSystem.GetDriveInfo("C:")
MsgBox("Total free space: " & CStr(cdrive.TotalFreeSpace))
I'm trying to make the progress bar to display the amount of free space C: has. I have successfully do so with my code which is:
Vb.net
Try
Dim b As String
Dim c As String
Dim dvr As New DriveInfo("c:")
b = CStr(dvr.TotalSize 1000000)
c = CStr(dvr.AvailableFreeSpace 1000000)
[Code] .....
As a last touch to this code I thought I would add a percent bar so it would look more professional. I did so with:
Dim Per As String = (c b * 100)
The problem is that it displays always zero percent why?

View 4 RepliesIf I increase the capacity of a given list, or add elements until count>capacity, does this mean the program is actually copying the entire list's contents to a new space in memory (similar to redim preserve with arrays)? If so, than I have really been hurting the performance of my lists, as before I was inserting and adding without a second thought. This seems a strong restriction on the dynamic abilities of lists.

View 1 RepliesI am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)

View 11 RepliesI'm running into an issue with my application. If the laptop is just turned on and a user opens the application, the application attempts to hit a SQL server to do some work. The issue is that sometimes the SQL Server process hasn't started yet (slow laptop).
What is the preferred method for checking if this is running.
Do I check for it like a normal process?
Do I attempt to make a connection via ADO.NET and catch the error?
How can i check if the server is online or offline? I was thinking of using the Try and Catch method.
