Hello!
I am pretending to write a tapi related app. however I don't know how to record the voice on the phone line with tapi32.ddl.
If you know any sample code written in vb.net, it would be a great help to me.
Thank You!

That depends on what the C exe is able to do, whether by passing as params, by file, through database.

Is that one a serial-prorammed version? Anyhow checkout the PIC website[^] or Google for pic16f84. There's heaps of information in the net.

You need the System.IO.Ports namespace. It is in .NET 2.0.
Here is an article (in C#) on The Code Project[^] that should get you started.

Hi all,
i'm having problem on how to retrieve the value of each item in combobox.
I haven't select the item, but i just want to read each item in the combobox.
here is how my codes loook like:
dim drv as string
For i = 0 To Me.cboDrives.Items.Count - 1
drv = cboDrives.Items.Item(i)
If drv = "(C:\)" Then
PercentFree(drv, percFree)
GetFreeSpace(drv, freespace)
If percFree <= 15 Then
messagebox(...)
End If
End If
next i
When i run the codes, the error keep saying "Cast from type 'NameValue' to type 'String' is not valid."
Is there something wrong with my coding???
Thanks a lot in advance.
besah

Since this code is most probably retyped by you rather than a cut and paste, we can't really tell what if anything you have done wrong. Please copy the exact code.
Also, the error you received should have told you on which line it occurred. Telling us that will also help us diagnose your problem. Have you run the code in debug mode to attempt to diagnose the problem yourself?
Note that we should not have to read your entire code to do this - help us to help you.

I would experiment with breakpoints. The cast is obviously implicit because I don't see where you are performing an explicit cast.
I copied your loop
<br />
dim drv as string<br />
dim i as integer<br />
For i = 0 To Me.cboDrives.Items.Count - 1<br />
drv = cboDrives.Items.Item(i)<br />
next i
and I didn't get any exceptions, so the error is probably occuring in either PercentFree or GetFreeSpace

I'm trying to use a HttpWebRequest to login to a Breeze server. I've tried a WebClient also. I keep getting a '400 bad request' reponse from the server.
This URL works fine through a browser:
http://admin.breezecentral.com/api/xml?action=login&login=jon@doe.com&password=foobar
Its a test server so go ahead. Play with it.
Here is my code:
Dim encoding As New System.Text.UTF8Encoding
Dim PostData As String = "action=login&login=jon@doe.com&password=foobar"
Dim Data() As Byte = encoding.GetBytes(PostData)
Dim LoginReq As Net.HttpWebRequest = Net.WebRequest.Create("http://admin.breezecentral.com/api/xml")
Dim CookieC As New Net.CookieContainer
With LoginReq
.KeepAlive = False
.Method = "POST"
.ContentType = "application/x-www-form-urlencoded"
.ContentLength = Data.Length
.CookieContainer = CookieC
End With
Dim SendReq As IO.Stream = LoginReq.GetRequestStream
SendReq.Write(Data, 0, Data.Length)
SendReq.Close()
Dim LoginRes As Net.HttpWebResponse = LoginReq.GetResponse()
CookieC.Add(LoginRes.Cookies)
Dim sReader As IO.StreamReader = New IO.StreamReader(LoginRes.GetResponseStream)
Dim HTML As String = sReader.ReadToEnd
Debug.Write(HTML)
Please help. I'm sure I have some small setting wrong.

I found the problem. I was using a proxy server and had the port wrong. I didn't realize the error was coming from the proxy server. Otherwise my code was fine.

if you want to import System sounds like Asterisk,Beep,Hand and others you should import the namespace System.Media but if you want to add a project that plays any kind of sound formats you can use a DirectX component called Quartz.dll which is part of Windows MediaPlayer and Windows Operating system.This file you can find in this path: C:\WINDOWS\system32.Open the Visual Studio Command Line and type the following command:[WindowsDir]/tlbimp quartz.dll /out:QuartzTypeLib.dll.The [WindowsDir] is where your instalation of operating system is(in most cases C:\).I hope I helped you cause I had the same problem and should digging a lot to find a way to play sound formats.Best wishes!

Say you have a data grid that is filled from information pulled from a database. Now say you have 50 records that are put into the data grid, and you basically have a data grid with 50 records in one big column.
I want to know how to make it say 2 columns of 25, so it looks a bit better than just one big hug column that streches away off the bottom of the page.

try the requery method. Put it in the afterupdate event of your form. then you use requery method on the recordsource of your form.....try that
