Know A Process Is Finished?
Mar 9, 2010
I am using the following command to install a driver withing my program: Process.Start(Application.StartupPath & "USBG-232MM_Driver.exe")
This installs a driver for USB cable(not important).
1- I would like to wait untill the driver finishes installing before I go to next step. Is there anyway to know if this process is completed?
2- After I plug the USB cable the computer starts the detection. I like to know when the device is detected and ready.

When a button is clicked,my program gets the list of all Drives on a current computer.Then I use String.Concat to merge the drive letter and the rest of the path.So I get something like: "C:" + "somefoldersomefile.some_extension"That creates a full path to a file I am looking for.Then I check if that file exists.If it doesn't exist,I use Process.Start to run the setup file(to install the program I need).It works well and installs the program I need.I want my application,after the installation is finished,to check again if the program is installed and ofcourse confirm that it is.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim DriveList As String() = Directory.GetLogicalDrives()
Dim Drive, FullPath, Path1 As String
Dim EmptyDrives As Integer

I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

I have an application that allows the user to upload information from and Excel sheet. Since the user is more familiar with Excel, they prefer to do it this way. My software will close the workbook with Me.exApp.Workbooks.Close() , but if you have the task manager running, you can see the Excel application continues. I know the workbook is closed, b/c it asks if you would like to save changes. One instance of Excel will close when the program is exited, but the user normally builds a folder of Excel files and does them all at once. If 8 instances of Excel exist, only one will close with the program.

I've made a tabbed web browser and I'm using
CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Stop()
instead of WebBrowser1.Stop() for navigating.
but I want to know when a web page has finished loading?
Normally the following works, but not with tabs
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
End Sub

I have a piece of my code that uses a for each to loop a certain amount of times depending on how many saved fields there are in an xml.
vb.net
'// Write an .html file ready for debugging
If (File.Exists("Working/" & textBoxCampaignName.Text & ".html")) Then
'// Do nothing the file exists
[Code]....
So the for each loops depending on how many nodes it finds in the ("/campaign/secondarySection") this works great, it loops accordingly, what i'm trying to figure out is a way for a messagebox to show once the loops are finished, i can't think of a way to find out once the loops are done.

I'd like to know... well, I have finished a project managing databases and all that stuff... and using ADO.NET, some databases and the main program, I'd like to compile it all to make an installation and use those databases.If I use the exex that is inside the debug folder... in other computers gives error and don't show the content of the databases. What I want is just the exe but with the databases visible in the other cpus, how to install the app in any windows computer and what I need to know or give is:
If I have my installator and I give this to a friend, he can use the databases ? He need the SQL 2005 Management to see that content of the databases ? Or I can just give him the program and work with the databases??

how to cause it so that my program will not proceed while a web page is loading. For example, if I use this:
webbrowser1.navigate(www.amazon.com")
sometimes it will have finished loading the webpage before the program proceeds. Other times, even if it says it is done, it is not done and it causes my program to crash.
how I can cause my program to stop and wait until it is sure the webbrowser has completed loading?

I have recently developed and finished a software in which works like aim.But here's the problem, the server worked just fine for local friends because they lived only 25 miles from the server, so it was lag-less.But when uploaded to a web host, it lags every time it pings the server.The server is in PHP, so there's no need to buy a dedicated computer for 400$/month more.Here's the function in which the client constantly calls upon:
[Code]...
I was thinking about recoding the getpage function so that it would connect to a TCP server and constantly wait for new messages which I am still not sure if this might cause a lag if the host is in the US and the client is not(for example). provide me a remedy to this problem?

I built a program in visual studio 2005 that access a Microsoft Access database. I need this program to be a standalone program on many machines. To do this, I need to install a copy of the database when the program installs. I tried including it in the application files part of the build, but the problem I am having is the connection strings dont update with the install. It still tries to point to the folder it is in on the comnputer i built the program.

I need to unzip en zip some files in my application using Shell32. Right now, I use srcFolder.CopyHere(destFolder.Items()) to achieve this. However, my next line of code requires the newly made ZIP-file. But since the CopyHere method is Async, how can I check when it in finished? Right now I use a Thread.Sleep for around 500 ms which is enough for my computer to finish creating the ZIP file, but it's not good code imo.

I'm running three subs in turn (one for each stage of the process that I'm carrying out).The first two of them run a VB Process using:
myProcess.StartInfo.RedirectStandardOutput =
True
[code]....
They then use the StandardOutput of their process to update one TextBox that I'm using for the output of all three stages.The final sub uses the shell because I can't get the EXE that I'm running with it to work properly using a process (this is not necessarily the problem though).The problem is that nothing changes in my textBox until the final sub has finished. The first two sub's output doesn't appear even though this should be just a linear process...

How can I stop my application quitting until a backgroundworker has finished? Its an updater, so basically I want the form to hide until the download is finished, and then exit.I've tried to make a setting to tell the app when it is still downloading, and on form closing check this variable, but it won't work. For some reason it still quits!The update window is in a separate form to the main form, so the user clicks 'Finish', the update form closes and the main form stays open.[code]
