This is because your application is not yielding every once in a while so it's message pump can execute. Inside the loop that is processing your records, include a Application.DoEvents() statement.

The TAPI 3.0 wrapper has "issues" to say the least. Your best bet is to use TAPI 2.0 instead. There is a wrapper class available on GotDotNet, here[^].

Hi all,

I would like to know how to share a folder which is on the C drive of a PC which is on a network.

I have 2 computers hooked on to the server.

On the first machine (C DRIVE) I have created a folder and set its property to sharing.

From the second PC I want to access only that folder of the first PC.

The Server is on Win2003 and the workstations are on win2K
I have Administrative rights too.

can some one help
Tnx

Your question has nothing to do with VB.NET. Post it in the Operating SYstems/SysAdmin Forum[^].

You should post this question to the Operating System forum, but anyway I still answer your question.

In case if you are using client/server with DHCP server, you must know the computer name and share name of your folder. If you the first PC name pc1 and the share folder name is test then on the second PC go to Start menu -> Run and type \\pc1\test and press enter.

In case if you are using static IP address of each machine, you must know the computer name or an IP address of the destination machine. If you the first PC name pc1 with IP address 192.168.1.10 and the share folder name is test then on the second PC go to Start menu -> Run and type \\pc1\test or \\192.168.1.10\test and press enter. But make sure that you have the following options:

1. Client: Client for Microsoft Network.
2. Service: File and Print sharing for Microsoft Network service.
3. Protocol: TCP/IP protocol.

A thousand mile of journey, begin with the first step.

I would appreciate it if some one could help me. I don't know how to write the code to save or save as in my forms. Here is the code that I have so far. Note that my parent form has file(new,open, save, save as, close) on it. I have already done the new code and I have been searching through the help files of .Net for 2 hours now with no help what so ever. Also please note that opion strict is set to on.

this is the code in my child form.

if all you need is to write to a file, simply use the FileStream object in the frameworks
(if it is then the title of your message is VERY misleading, if not, then my reply is useless Smile | :)

)

the basics are to create a FileStream object reference

Dim MyFileStream as System.IO.FileStream

and then you need to create the file stream, by opening the file
if it is a new file (there isn't a file with the same name at the same directory)
you should create the file like so:

MyFileStream = IO.File.Open(MyFilePath, IO.FileMode.CreateNew)

if the file already exists, you would probably want to erase the data and rewrite it do:

FileStream = SystemIO.File.Open(MyFilePath, IO.FileMode.Truncate)

to check whether the file exists use:

If System.IO.File.Exists(MyFilePath) Then ...

if you want to be really smart about it, you can scan the file to see what segements of have been chaged and only write those parts (mostly usefull in large files)

The 'X' click event

Brad Fackrell9-Nov-04 11:33

9-Nov-04 11:33

Does anybody know how to get the ‘X’ click event?….the ‘X’ in the upper right hand corner of a form.

I want to perform a function if the ‘X’ is used to close the form (something like frmMain_ClickX) but if I use frmMain_Closing it causes certain functions to execute twice.

I’m assuming that frmMain_Click is not specifically associated with the click event of the ‘X’.

Thanks
Brad

Private Sub whatever_you_want(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing

Brad Fackrell10-Nov-04 3:46

10-Nov-04 3:46

I’m still a bit confused.

I have the following sub that I want to be sure is executed whenever the form closes:

SaveData()

I have programmed the sub ‘SaveData()’ to execute under the ‘mnuExit_Click’ (and other areas).

My problem is that ‘SaveData()’ is executed once when ‘mnuExit_Click’ is executed and then again during frm1_cloising.

I assume that it is bad practice to just execute ‘SaveData()’ in ‘frm1_closing’ and in no other location.

Thanks
Brad

The reason why it's getting executed twice is because you execute it in the mnuExit handler AND your doing it again when the Closing event is fired. If you want to handle all possible ways of closing a form, then the Closing event is the way to go...

Okay. I thought that would work but then I "second guessed" myself because I thought; Why add any sub routines under mneExit?

Thanks Dave.

Replace SaveData() in mnuExit_Click and all other locations (except frm1_closing) by Me.Close().
