i've problem when i try to start the server application, my application getting freeze until iconnect the client application.. why this happen? and how to solve it.. here is my code for start server button..
Dim port As String
Try
MyUpdateTextBox = New UpdateTextBox(AddressOf UpdateTextBoxDelegate)
Dim tcpserver As New TcpListener(TextPort.Text.ToString)
tcpserver.Start()
port = TextPort.Text
Dim tcpClient As TcpClient
tcpClient = tcpserver.AcceptTcpClient
MessageBox.Show("connected")
networkStream = tcpClient.GetStream()
networkStream.BeginRead(buffer, 0, buffer.Length, New AsyncCallback(AddressOf MyReadCallback), buffer)
Synchronizer = Me.ReceiveBox
Catch ex As Exception
MsgBox("Cannot connect to the specified address or port")
End Try
|
|
|
|
|
tcpserver.Start()
If you ask me, that starts a server, and does not connect to one. A TcpListener waits for incoming connections and accepts them. You should make a server application that listens, and a client that connects to the server. Try using the ip "127.0.01" to test locally.
Good Luck!

i've make a client application that try to connect to server.. and i've been test it to connect to other server applcation, and its work..
and now, i want to make a server application(because the server application that i used to try to check my client application is the application that i buy from someone, so, no code).. so i think tcpserver.start() has nothing wrong is it? if i remove that code it will be no connection.. maybe other web reference that u can tell me could be help me coz i've been google to search the best code that can help me but all dont satisfy me....

Before i tear my thinning hair out, is it possible to launch an app by having a splash screen and then login form show, and if the login is correct then close this down and launch the main app as MdiParent with Children forms as user input, I am presuming this will allow me to catch if a path to the database is ok before launching the main app. (At the moment i am opening the MdiParent and hiding it, then displaying the splash and then logon. It doesn't look pretty.)

If the main app is a seperate exe, what stops people bypassing your login ?

I use the following process
Application entry point is Sub Main.
Display the splash screen with form.show
Do the login useing a form.show (we use a seperate DLL for this)
if the validation is successful then do the Application.Rum(mainform)

I have a sql database that has multiple fields that I pull data from. On my visual basic form I have combo boxes that are linked to the database. Selecting the data I need, I push a button and I need the application to open a word document that is already prepared, pull the data from the data base and insert the data into specific fields in the document then print it. I don't need to save the document just close it.
I have the VB form and I can select the data and I can open the word doc. But how to write the data to the specific location on the word document is the trick I am having problems with at this time.
All help is appreciated
If any more info is need please ask.
Also if this is not the right forum please direct me to the one I need.

Hey, I am trying to load an rtf document into a RichTextBox control from a file but nothing I do seems to work. I have tried the LoadFile method with no results as well as reading the file into a string and setting the Rtf property. Originally I thought there could be a problem with document so went into Word, created a new one, and saved it as an rtf. That still didn't work though no errors are being thrown. The Rtf property just returns to its default value and the Text property stays "". Anyone have an idea on what I am missing? Thanks!
This is one way I tried it...
Dim FSI As New FileStream("C:\RTFtest.rtf", FileMode.Open)<br />
Dim SR As New StreamReader(FSI)<br />
Dim strRTF As String<br />
<br />
strRTF = SR.ReadToEnd()<br />
strRTF.Trim(vbCrLf)<br />
rtbBox.Rtf = strRTF
And the 2nd way...
rtbBox.LoadFile("C:\RTFtest.rtf")

Hi Justin,
There is nothing wrong in your code. I have tested them and both method works fine. The only thing I suspect is the .rtf file you are reading because this code does not read an rtf file which contains lots of images, styles or graphics etc. I have uploaded a sample application which implements the desired functionality using same code snippet. Take a look and see if this helps. You can download the application from the following link

On a certain condition, I want the focus to start with a different control then the first one. No matter what I do it won't listen to the command textbox7.focus. In the form load I put the command. In form activate I put the command. Is there an alternative to have to create something like a timer to activate to set focus after the form is fully visible...
Any tips would be appreciated...

Hello Nathan,
You can try setting the TabIndex property of the control. You can use this in Form_load event.
TextBox1.TabIndex = 0
I hope this helps.

if that control is the first or last textbox then that's ok solution. however by doing so wouldn't that screwup the tab order for the rest of the controls?

incase anyone is curious you need to use the paint event and setup a static variable to only issue the focus command once...

My question is related with VBScript.
But i didn't saw any topic with that one.
I have a small problem with a script.
Used this command : ret=objShell.run (strCommand ,0 ,true). Where strCommand runs 7-zip to do an archive. The problem appears if some files are in use by another process. 7-zip return and error code and the program stops there. I want the program to continue the execution because even with this error.
If I put the last parameter false the problem is that that the program doesn't wait for the archive to be done.
I looked for some hours on the net but didn't find anything so I'm a little desperate.
I really appreciate any help,
Thanks

The problem is with 7-zip rather than the VBScript.
check the parameters that are available for 7-zip. I suspect that 7-zip has encountered an open file and aborted, rather than continue on to the next file to compress.

no, he continue to compress the files and when he finish he throw this warning.
But the shell.run function see that the return code isn't 0 and suspend the program util I close the windows that 7-zip opened.

YOu should use Path.Combine, not string mashing blindly. I guess the file is not there Have you tried debugging ?

Hello friends,
1)I've created one VB.NET dll.
2)I've created the .tlb file of this dll to use it in VB 6.0.
3)I am able to add the refrence of this .tlb file in the applicaiton.
But when I want to create the object of the class of this library using new method the library created in VB.NET doens't even appear in the list to create the object.
The code of VB.NET dll is as below.
Imports System<br />
Imports System.Reflection<br />
Imports System.Runtime.InteropServices<br />
<br />
<Assembly: AssemblyKeyFile("mykey.snk")> <br />
<br />
<ComVisible(True)> _<br />
Public Interface IAClass<br />
Function GetCurrentTime() As String<br />
End Interface<br />
<br />
<ProgId("MyCompany.MyLib.AClass")> _<br />
Public Class AClass<br />
Implements IAClass<br />
<br />
Public Function GetCurrentTime() As String Implements IAClass.GetCurrentTime<br />
Return System.DateTime.Now.ToString()<br />
End Function<br />
End Class
I've created the .tlb file from this dll.
The code of the VB 6.0 Application is as below.
Dim ob As SampLib.IAClass<br />
Private Sub Command1_Click()<br />
Set ob = CreateObject("SampLib.IAClass")<br />
MsgBox ob.GetCurrentTime<br />
End Sub
Please if anybody can tell what is the reason that doesn't allow me to use the .tlb file in VB.
Thanks in Advance to all of you.
