"Adobe Reader could not open text.pdf because it is either not a supported file type or because the file has correpted."
The code is as follows.
Try
Dim document As New Document()
PdfWriter.getInstance(document, New FileStream ("C:\html\sample.pdf", FileMode.Create))
'Dim handle As New ITextHandler(document)
Dim handle As New ITextmyHtmlHandler(document)
handle.Parse("C:\html\sample.xml")
Catch ex As System.Exception
Console.[Error].WriteLine(ex.Message)
Console.[Error].WriteLine(ex.StackTrace)
End Try
Thanks and Regards,

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

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.

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.

I am a new to the world of VB.Net and programming in general. I am attempting to add a very basic undo / redo feature to a paint type application that uses a shape (line, box, circle, etc) collection object. I am lost as to how to implement this feature. Can anyone provide some basic ideas? Thank you.

Do a google search on: "VB.Net"+Undo+Redo
may your code be error free.
(okay, maybe two lines.)

We are integrating different systems into one solution, each system is consisting of one project and we are using source safe to maintain our codes. we are having problems in downloading one project for each programmer, how can we distribute each project without downloading the whole solution.
for example, we have 2 programmers and 2 dependency projects, let's say programmer A and programmer B, project A and project B, respectively. Those projects are dependencies of project C. We are avoiding each programmer to download both project A and B.

I am trying to read a list of PointPairList points and put them into an array. I want to perform some math functions on the list of points. Also I am only going to want the y points in the list. Wonder if that is possible? The y points are values and the x points are just points for time.

You' going to have to use the forums[^] for Zed Graph for this question. What you're asking has nothing to do with the .NET Framework or VB.NET.

I'm writing a small app in Access using VB. I need to loop through all of the control names in the form and then delete the one in which the control name is "Title", and which is a label.
'Suppose all declarations are already made'
For Each ctl In frm.Controls<br />
If ctl.ControlType = acLabel Then<br />
If ctl.name = "Title" Then<br />
ctl.?????? - removing/deleting step<br />
End If<br />
End If<br />
Next ctl
I don't know how to actually delete the controls. I can ADD controls and EDIT them OK, but deleting them is misleading me. Any ideas? Thanks.

That's not VB. It's Access VBA.

Actually, I've seen VBA questions here before. VBA is more VB than it is SQL, I'd say the problem is that we really don't have a 'right' forum for this question.

Just guessing... but isn't frm.Controls a collection? If so, you should be able to delete from it?

I am working on a class project and want to make sure I am on track. Right now, I have a single Access Database with nine tables. In the project, I have one binding source and one dataset. I also have a Binding Source and a TableAdapter for each table. Is this way it is supposed to work, or I doing something very wrong?
If anyone has a few good current articles I would appreciate it. All I found on google was for vb6 or SQL.
Thanks

That's one way of doing it. The 'right' way to do any sort of DB code is to have a seperate dll to handle all database access, and to write methods for each database call you're likely to make. This would not involve any sort of binding sources, you'd write actual code to connect and call database procedures.
However, for a class project, the way you're doing it will work just fine, and be a lot less work.

I am trying to use the Visio Drawing Control in a vb.net windows application but keep getting an error everytime I try to drag the control onto my form. I am using VS2003 and I have Visio 2003 installed on my machine. I have added the control 'Microsoft Visio 11.0 Drawing Control' to my toolbox. Whenever I try to drag this control onto my form I get the following two errors:
'An unspecified error occured' and then
'Unspecified error'
I have tried to uninstall/reinstall Visio 2003, the Office 2003 PIA's and nothing seems to work.
Any help would be greatly appreciated.
Thanks
Matt

I think I may have figured out why this is happening. When I installed Visio 2003 (months ago) I never bothered to register it. For a while I was able to use this drawing control on other applications with no issues. After a certain amount of time or amount of times used visio will disable some of its functionality until it is registered. Because I was not actually using visio I did not notice this. The drawing control must have been encompassed within the functionality that was retricted. Once I registered visio I was able to use this control once again. Thank you to all the people who tried to help.
Thanks
Matt
