Yes, you can use the File handling APIs to rewrite the files on disk thus modifying the application.

Hi!
My aim is to scroll richtextbox automatically according to serached and found text in it. How can I do that?
Thanks

Hi,
You can do this by using the Find Method of RichTextBox. Below is the code snippet for the same.
BEGIN CODE
PrivateSub btnFind_Click(ByVal sender AsObject, ByVal e As EventArgs)
Dim startindex AsInteger = 0
If txtSearch.Text.Length > 0 Then
startindex = FindMyText(txtSearch.Text.Trim(), start, rtb.Text.Length)
EndIf
' If string was found in the RichTextBox, highlight it
If startindex >= 0 Then
' Set the highlight color as red
rtb.SelectionColor = Color.Red
' Find the end index. End Index = number of characters in textbox
Dim endindex AsInteger = txtSearch.Text.Length
' Highlight the search string
rtb.Select(startindex, endindex)
' mark the start position after the position of
' last search string
start = startindex + endindex
EndIf
End Sub
END CODE
Hope this helps  .

Hi to all
if i type B in text box which is for qualification of user input then
it should write like B.COM or B.E.
Thanks & regards
Sonia.

Use combo box that will solve ur thing

Try with windows registry methods such as
GetFromRegistry and SetRegistry so to retain the default values.

Now I want to set the Wrap Text property to True of the newly created file.
Is there any way I can do that?

Hi,
I have a doubt whether is it possible to create an object on another Thread. I'll explain with an example:
<br />
<br />
Public Class GSM<br />
Private m_Port As SerialPort<br />
Public response As String<br />
<br />
Public Sub OpenPort(ByVal PortName As String)<br />
Try<br />
m_Port = My.Computer.Ports.OpenSerialPort(PortName, 115200, Ports.Parity.None, 8, Ports.StopBits.One)<br />
Catch ex As Exception<br />
'handle exeption<br />
End Try<br />
End Sub<br />
<br />
Public Sub ClosePort()<br />
m_Port.Close()<br />
End Sub<br />
<br />
Public Function IsOpen() As Boolean<br />
Return m_Port.IsOpen<br />
End Function<br />
<br />
Private Sub write(ByVal mText As String)<br />
m_Port.Write(mText)<br />
End Sub<br />
<br />
Private Sub Read()<br />
response = m_Port.ReadExisting<br />
End Sub<br />
<br />
End Class<br />
<br />
This is my object GSM and now I want to use it on with my form so :
<br />
Dim myGSM as GSM<br />
myGSM = New GSM<br />
myGSM.OpenPort("COM1")<br />
but if I want to use it in several parts of my code it will be a mess trying to launch it on seperates threads. So is there a way to tell visual that this object GSM is a seperate thread itself ... so I will only have to write MyGMS.write("blabla") from my form?
thank for the help ...

Hi,
It sounds like the DLL is not properly creating the PDF file.

I am using Stored Procedure for viewing crystalreportviewer in vb.net
and i am passing 3 parameters to the stored procedure tooo.
but when ever i run the page its always asking the parameters.
Dim myReportDocument As CrystalDecisions.CrystalReports.Engine.ReportDocument
myReportDocument = New CrystalDecisions.CrystalReports.Engine.ReportDocument
myReportDocument.Load(ReportAddress & "InvoiceRenewal.rpt")
objCmd = New SqlCommand("sp_InvoiceRenewal", objIDB.OpenConnection)
objCmd.CommandType = CommandType.StoredProcedure
objCmd.Parameters.Add(New SqlParameter("@intID", SqlDbType.Int, 10))
objCmd.Parameters("@intID").Value = Request.QueryString("ID")
objCmd.Parameters.Add(New SqlParameter("@NoOfEachPlan", SqlDbType.Int, 10))
objCmd.Parameters("@NoOfEachPlan").Value = NoOfEachPlan
objCmd.Parameters.Add(New SqlParameter("@Names", SqlDbType.VarChar, 2000))
objCmd.Parameters("@Names").Value = names
objDa.SelectCommand = objCmd
objDa.Fill(objDs)
myReportDocument.SetDataSource(objDs)
CrystalReportViewer1.ReportSource = myReportDocument
CrystalReportViewer1.DataBind()

Hi Everyone,
I've got an FTP problem. I've been trying to make my own FTP program but it doesn't quite work and I'm not sure why.
Dim FileName As String = xmlFileName
Dim ftpServerIP = "202.62.33.220"
Dim fileInf As New FileInfo(FileName)
Dim uri As String = "ftp://" + ftpServerIP + "/" + fileInf.Name
Dim reqFTP As FtpWebRequest
' Create FtpWebRequest object from the Uri provided
reqFTP = DirectCast(FtpWebRequest.Create(New Uri("ftp://" + ftpServerIP + "/" + fileInf.Name)), FtpWebRequest)
MsgBox("ftp://" + ftpServerIP + "/" + fileInf.Name)
' Provide the WebPermission Credintials
reqFTP.Credentials = New NetworkCredential("MHR\administrator", "sbanks@#@")
' By default KeepAlive is true, where the control connection is not closed
' after a command is executed.
reqFTP.KeepAlive = False
' Specify the command to be executed.
reqFTP.Method = WebRequestMethods.Ftp.UploadFile
' Specify the data transfer type.
reqFTP.UseBinary = True
' Notify the server about the size of the uploaded file
reqFTP.ContentLength = fileInf.Length
' The buffer size is set to 2kb
Dim buffLength As Integer = 2048
Dim buff As Byte() = New Byte(buffLength - 1) {}
Dim contentLen As Integer
' Opens a file stream (System.IO.FileStream) to read the file to be uploaded
Dim fs As FileStream = fileInf.OpenRead()
'Try
' Stream to which the file to be upload is written
Dim strm As Stream = reqFTP.GetRequestStream()
' Read from the file stream 2kb at a time
contentLen = fs.Read(buff, 0, buffLength)
' Till Stream content ends
While contentLen <> 0
' Write Content from the file stream to the FTP Upload Stream
******strm.Write(buff, 0, contentLen)*********
contentLen = fs.Read(buff, 0, buffLength)
End While
' Close the file stream and the Request Stream
strm.Close()
fs.Close()
'Catch ex As Exception
'MsgBox(ex.Message, "Upload Error")
'End Try
Where all the stars are is where the error occurs. The error message is this: (421) Service not available, closing control connection.
Does anyone have any ideas? I was thinking it was something to do with no port declaration but I'm try to find out how to declare one to see if that fixes the problem.
All your help is muchly appreciated in advance.
Cheers.
Michael

Hm, code looks correct on a quick view. Since you provided user/pass for that ftp server i tried a connection and got:
E:\WINDOWS>ftp
ftp> open 202.62.33.220
Verbindung mit 202.62.33.220 wurde hergestellt.
Verbindung beendet durch Remotehost. ("Connection terminated by remote host")
Connection with an ftp client(ultrafxp):
Network subsystem is unusable
Seems to be a server issue, try your code on another server to see if code is working :p

hi guys
i have a class library project named jdl, in this project i have a class named Constants,
i have a public constant readonly string in this class whic is assigned the value of "NY"
now i am facing a probelem it is not giving me the currnet value , it is giving me a previous value which i assigned to this variable so other time , why is that ?
i have unloaded and loaded the project, i also have created an other project and in this project i referenced to this project but the problem still persists.
any hint , solution , thanks in advance
hello

As it's a constant, the value is copied into the code that uses it when it's compiled. You have to recompile the code that uses it for the change to take effect.

ok
i am facing a problem , thre is no debug, release folders under bin folder of my project,
exe is created under bin folder and all other referenced assemblies are also in the bin folder ,
why ?
thanks in advance

There doesn't have to be any. The build settings for the solution configuration contains the output path, which you can change to anything you like.
ghumman63 wrote: and all other referenced assemblies are also in the bin folder
Each reference has a setting whether it should be copied to the output path or not. Framework references and GAC references are not copied, other references (files and projects) are.
