VS 2008 - WinXP Ping Successful But Not Win7
Jan 19, 2012
I have a sub that I just discovered does not work for my windows 7 users but works fine for my windows XP users. This is basically a sub for a ping monitor to ping devices on a timer. What happens is that when the windows 7 user tries to ping, it always reports "down" on a windows 7 whether actually up or down. But, windows xp will report correctly with "up". 3 different windows 7 boxes, users say it worked before. Can't quite debug correctly as i'm on xp myself and it works just fine. Also, I haven't changed anything in the code in quite awhile and this is a recent bug that just started.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim itm As Object
Sec = Sec - 1
If ListView1.Items.Count = 0 Then Me.Close()
If Sec <= 0 Then

Within a VB.net program I used IO.File.GetCreationTime to read the file system's creation time of a file. I was irritated, because the returned value didn't match with the time displayed in the explorer. On another machine the time was displayed correctly.

ive decided to try out win7 since its finally a bit more debugged, ive backed up very carefully all my projects, however there semms to be a problem with the one i was working on, this first chance exception error has been avoided and not even mentioned in winxp however in win7 it not only mentions it but makes the application crash, This is what its nagging me about, i dont get it isnt windows7 the same when it comes to mydocs? Was not possible to locate part of the path: C:UsersEugenDocumentsIOrganizeSettingsCalendarConfig
Sorry i had to translate it, its in portuguese language, yeah i know... if i could i wouldve changed it but win7pro doesnt gimme that option, anyways back to the topic:
A first chance exception of type 'System.IO.DirectoryNotFoundException' occurred in mscorlib.dll
This is the code i came up with:
If My.Computer.FileSystem.DirectoryExists(My.Computer.FileSystem.SpecialDirectories.MyDocuments & "/IOrganizeSettings" & "/CalendarConfig/") = False Then
My.Computer.FileSystem.CreateDirectory(My.Computer.FileSystem.SpecialDirectories.MyDocuments & "/IOrganizeSettings" & "/CalendarConfig/")
End If

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

I was trying to edit to get the reults output to a text file. I needed to do this for a few hundred IP addresses, and found kleinma's code. It works great as is, but since the number of IP addresses to ping is so large, I lose some of the info from the console session. I tried to make changes to write the information into a text file, but it doesn't output the results. I am relatively new to VB.NET, so I was wondering if you could please point out the flaw(s) in the edited code. I was trying to use the My.Computer.FileSystem.WriteAllText(File, lineContent, True) method to do this. This does export the IP address list just fine, but the results of the async ping to not get output.

I created an application for Windows XP, now it needs to run on Windows 7. I have had some issues to resolve, but rather small ones. I am now stumped on this one... Here is my code block
vb.net
Private Shared Sub RenameFileAfterDownload(ByVal File As String)
Try

The code works perfectly for Windows XP, but the ftpRequest does not work in Windows 7 for renaming. That said, the code runs that entire sub becaues WriteToEventLog get's written, but seems to ignore the ftpRequest lines.

I have an app developed in VB that works fine on Vista machines but fails on Win7. The offending line of code merely references a variable stored in a module. Evidentally, something is quite different on Win7. How to I find and fix this behavior?
The code is very straightforward. The error occurs in the Application Startup event.
Public Sub MyApplication_Startup(ByVal sender As Object,
ByVal e As ApplicationServices.StartupEventArgs) _

Is there an easy way to just ping a server by IP or URL and return the minimum, maximum and average milliseconds? Actually the same results I get in CMD when using the ping command. Can't find any tutorial that describes it. So let's say I have a Textbox1 and a Button1 and a Label1 for the results. How can I do it?

I work as an IT Administrator and manage a few Servers, Routers, VPN Connections over a number if locations. What I am wanting to do is create a vb.net app that will go out and ping say every 2-5mins each of the servers, routers, that are listed and then shows beside the Hostname a Green Circle which means online and if its a Red Circle its offline, and the screen refreshes if their is a problem or a device / service comes back online.
Then if its offline email a particular email address showing the hostname of either the server or router and which location saying its offline. If possible to make it easier to change the devices to show possible have a txt file or something like that with the Hostname, IP Address, Location.

It seems like this would be a very easy thing to accomplish, but, from what I can tell, it's most definitely not. My OS is Windows 7. All I need to do is get the current volume/audio level - the master volume. When you click the little speaker icon in the task bar and change the volume - I need that number. All I need to do is get the current volume and assign it to a label. So if the volume is at 74 when the application starts, I need my label to display 74. I've been searching for days now for a way to do this and I'm starting to get frustrated. I've looked everywhere. I've tried 3 different classes, at least a dozen different codes, assorted imported dll's- none of it even came close to what I need. From what I can tell, the current methods are all designed for windows xp. I need a way to do it in windows 7.

My app is a tray icon which scans the Outlook Inbox periodically. It seems, from testing in my VMWare WinXP machine, that the app stops Windows from shutting down. I press StartShutdown but nothing happens. I have to exit the app first then StartShutdown will shutdown the PC.

I am wondering if I can use VB.NET(I am using visual studio 2010 express) to get and set a environment variable.
I want to add path of my application on system environment. I want to preserve what is already there and then I wan to add my string. This can be done by getting value of PATH and then append my string then re writing it.
I have 2 questions here:
How to get/set system variable in vb.net 2010? Will it be on the fly, I mean will it be immediatly avaialble in dos prompt or there will be delay?
As just for experiment i opened a command prompt then updated the PATH variable manually and it was not updated. I am wondering it I do it through programe it will be same.

I've found this code and it works in XP: [code] When I run the same code in Vista, I get an exception at the line "System. Environment.Get FolderPath(":See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. [code] I assume this has to do with the Vista UAC. Is there a better way to retrieve the "My Documents" path of either XP or Vista with one piece of code?

The code i have so far inputs the users username and pas that they inputted into 2 textboxes. Next the user hits login and it submits the info. Here is where i have a problem. Some users are already logged in when they get to the site, this is a problem because i need to make sure they are logging in correctly. Here comes another problem, lets say they log in correctly, how can i know that the login was successful?
Simplified:
1) How can i find out if the user is already logged in so i can log them out.
2) If they are not logged in, and they log in successfully. how can i confirm that?
If there is any other way to login without web browsers?
'Code to enter the user and pass into the webpage
WebBrowser1.document.GetElementById("Username").InnerText = TextBox1.Text
WebBrowser1.document.GetElementById("Password").InnerText = TextBox2.Text
'Code to click login on the webpage
WebBrowser1.document.GetElementById("submit").InvokeMember("click")
