little coding help needed

hey folks,
here's what I wanna do:
I need a program that runs in the background and checks if my mda2 is in the cradle or not. if it's plugged in the cradle I want it to change in my connection settings from work to internet. I need this for the following reason: my cellphone provider only offers grps over a proxy and that proxy wount work in the cralde when I share my PC connection via active sync. so right now I always need to switch between work and internet connection by myself.
I only know visual basic so I guess I need to take a look at eVB.
Is such a tool even possible in eVB? if so, where would I start? can someone point me in the right direction? maybe give me some links for research.
thanks for your help in advance

ait, did some research.
looks like just turning the proxy off should do the trick.
I tried doing this via the registry.
for now I just wanted to read out a key. this is what I got so far:
Code:
Option Explicit
Public Declare Function RegOpenKeyEx Lib "Coredll" Alias "RegOpenKeyExW" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, ByVal samDesired As Long, phkResult As Long) As Long
Public Declare Function RegQueryValueEx Lib "Coredll" Alias "RegQueryValueExW" (ByVal hKey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, ByVal lpData As String, lpcbData As Long) As Long
Public Declare Function RegCloseKey Lib "Coredll" (ByVal hKey As Long) As Long
Const ERROR_SUCCESS = &O0
Const HKEY_LOCAL_MACHINE = &H80000001
Private Sub Command1_Click()
Dim lngSize As Long, hlngSubKey As Long
Dim lngType As Long, lngResult As Long
Dim RegData As Integer
lngSize = 256
RegData = String(lngSize, 0)
lngResult = RegOpenKeyEx(HKEY_LOCAL_MACHINE, "\SOFTWARE\Microsoft\ConnMgr\Providers\{EF097F4C-DC4B-4c98-8FF6-AEF805DC0E8E}\HTTP-{18AD9FBD-F716-ACB6-FD8A-1965DB95B814}", 0, 0, hlngSubKey)
lngResult = RegQueryValueEx(hlngSubKey, "Proxy", 0, lngType, RegData, lngSize)
MsgBox RegData, vbOKOnly, "o2 proxy"
lngResult = RegCloseKey(hlngSubKey)
End Sub
Private Sub Form_OKClick()
App.End
End Sub
unfortunately when I press the button I only get a blank window. it wount show the proxy.
can someone tell me what I'm doing wrong?
oh and I still dont know how I could detect wether there is an active sync connection open or not. any ideas on that?

uhm, no one here who knows some eVB?

RegData should be declared as
Code:
Dim RegData As String

thanks for the answer but changing it to string didnt help. I still get an empty msg box.
any other ideas what I'm doing wrong?

Hi,
1) I wouldn't use lRetVal for the last parameter and the return function value. The last parameter returns the disposition value and the function return value returns 0 for success or an error that you can find in WINERROR.H and so in MSDN documentation.
If it is not the problem then:
2) In place of trying to create a key in HKLM, try first in HKCU, maybe the problem doesn't reside in the code but in the fact that you are trying to create a key in HKLM where you need "authorization" to do it. Your application needs to have privileges like being signed.
Hope it helps,
Cheers,
.Fred
ps.: use a real program language like C/C++. VB is crap!!!

[REQ] Game Server Monitoring like HLSW

Hi
Does anyone know a tool, which allows monitoring and rcon commands to be send to a game server via pocket pc?
I'm running an Enemy territory server and would like to see the status from time to time without switching on my real computer.

If you able to program its a easy thing:

"ÿÿÿÿ" is standing for a special type of character compression, just forgot the name but in my tool iam ignoring it

Here I started such an idea of a tool in vb.net , but i have no time to complete it

****. i have no clue about vb.
but thanks already. maybe someone can finish it.

That would be a cool application, if someone could code it.

Hmm...
I'll try to work on it....not sure where im gonna get!

timer in vb.net cf

I am trying to create a simple stopwatch like app and am having a hard time figuring it out.
in vb.net i can simply use Timer.Start() or Timer.Stop()
This will not work in the .net cf though. I googled the topic for over an hour and did a quick search on the forum and found no result.
Can anyone help me with a way around this, there has to be something simple I am missing or another way to do it. I just need a timer i can start, stop, pause and resume.
Thanks in advance.

Set the timer's Enabled property to true/false.

that works to start and stop it but if i want to pause and then resume it starts from the very begging instead of where it was paused.
ex: pause after 10sec. wait 10sec and hit resume....the timer jumps to 20sec instead of going to 11sec

Why not increment a variable when the timer ticks? Post some sample code here and we could help you debug it....

Do the calculations by using DateTime and TimeSpan.

Code:
Public Class Form1
Dim startTime As DateTime
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
Dim span As TimeSpan = DateTime.Now.Subtract(startTime)
lblTimer.Text = span.Hours.ToString & ":" & span.Minutes.ToString & ":" & span.Seconds.ToString
btnStop.Enabled = True
btnPause.Enabled = True
End Sub
Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
startTime = DateTime.Now()
Timer.Start()
If (Timer.Enabled = True) Then
btnStart.Text = "Restart"
End If
End Sub
Private Sub btnStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStop.Click
If (Timer.Enabled) Then
Timer.Stop()
End If
End Sub
Private Sub btnPause_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPause.Click
If (Timer.Enabled) Then
Timer.Stop()
btnPause.Text = ("Resume")
Else : Timer.Start()
btnPause.Text = ("Pause")
End If
End Sub
End Class
now the problem is timer.start and timer.stop do not work as they are not included in the cf

I code in C#, but don't you need to declare a variable of type Timer to use it? I don't think there are any static methods for the Timer class.

the above code works fine in the standard .net framework but the start and stop methods are not in the compact framework so i need to find a way around that

Sorry, I got confused with the naming conventions - I thought Timer was a class reference.
Start and Stop works in the full framework, but the logic of your code is wrong - you are always subtracting the _start_ time from the current time when the timer ticks. This is why when you resume, it's still counting how many seconds has passed since you pressed Start.
This should work:
Code:
Public Class Form1
Dim startTime As DateTime
Dim span As TimeSpan
Dim hours, minutes, seconds As Integer
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
span = DateTime.Now.Subtract(startTime)
lblTimer.Text = span.Hours.ToString & ":" & span.Minutes.ToString & ":" & span.Seconds.ToString
End Sub
Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
startTime = DateTime.Now()
Timer.Enabled = True
If (Timer.Enabled = True) Then
btnStart.Text = "Restart"
End If
End Sub
Private Sub btnStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStop.Click
Timer.Enabled = False
End Sub
Private Sub btnPause_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPause.Click
If (Timer.Enabled) Then
Timer.Enabled = False
btnPause.Text = ("Resume")
hours = span.Hours
minutes = span.Minutes
seconds = span.Seconds
Else
startTime = DateTime.Now.Subtract(New TimeSpan(hours, minutes, seconds))
Timer.Enabled = True
btnPause.Text = ("Pause")
End If
End Sub
End Class
Man, coding in VB brings back memories...

...i see your point thanks a lot...as soon as i am done backing the hard drive up in my msi wind i will give this a shot...thanks again

Hiding/showing a form (vb.net)

I am trying to replace my contacts program with one I wrote myself but I'm having a little problem getting the form to hide and then show again?
I would like to start my app from a button, easy enough but I'm a little confused with hiding it again. I can hide the form but if I press the button again nothing happens but I'd like my app to show itself again?
Could someone please help the village idiot and point me in the right direction please?

Ok solved my problem. I used another exe to boot the program and if it was already booted then show the program via the API.
