how to convert pdf to html? by using source code

please read the sticky note on how to ask questions. All the questions here are about VB.NET, how does that help ?
A web server can serve a PDF directly. If you want to convert it to HTML, you need a PDF that contains text, not just images, otherwise there is little point. Even then, I'm not sure that any component exists, although components to return the text itself certainly do. There is no support for PDF in .NET, it's all via commercial libraries.

You need to either write code to draw a chart, or use a commercial or free library that does it for you.
If you want to write it yourself, read up on the Graphics and Bitmap classes.

If you can read the csv file in yourself (and honestly, that should be trivial), ZedGraph has some awesome charting capabilities, including bar charts.

Hi,
Can anyone tell me the solution to this problem. I have built a procidure wrapped in a class that takes a parameter.This procidure is called normally by starting a thread. When an event occures, it is required to call the procidure with new paramater.
A code snippet would be like this.
Private Sub btnReceive_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnReceive.Click
remote = New RemoteConnection 'this is the class
trListen1 = New Thread(AddressOf remote.ReceiveMessage)
remote.msg = "Message has been received."
trListen1.Start()
End Sub
Private Sub btnChange_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnChange.Click
If trListen1.IsAlive = True Then
trListen1.Abort()
Else
remote = New RemoteConnection
trListen2 = New Thread(AddressOf remote.ReceiveMessage)
remote.msg = "Message has been received,answer is here."
trListen2.Start()
End If
End Sub
But this does not work. How this can be handled?
Thanks.

Hi Reman,
What you are trying to do is reasonably clear, however...
Amer Rehman wrote: But this does not work.
is not.
How does it not work? Is an error thrown, or what? If so, at what point in this code? etc?

My advice is free, and you may get what you paid for.

How is it that a VB.NET beginner is using SQL Server and trying to write mission critical code for backing up data ?
Which bit are you stuck on ? How much SQL and VB do you know ?

If I understand you correctly you are asking how to backup your VB project code.
If I am correct in my assumption then all you need to do is backup the appropriate folder and all its contents within the projects folder.
So if your project is called UseTheForce the path to backup will be something like:
C:\Documents and Settings\HP_Administrator\My Documents\Visual Studio 2005\Projects\UseTheForce
This holds everything relating to your project.
I hope I got the right end of the stick and that this is of help...

how can i send a right click event to my application and more over can i get any help how can i simulate double click event in that same application.I want help in VB.net for these events any clue how can i impliment them
farah

Why do you want to ? Send them from where ? The obvious thing to do is to write a method that is called by your right click event, and call it when ever else you need to.

i just want to code a right click that works the same way as normal right click funtion does that is when i right click on any control in VB.net or over any where else outside my VB.net application it performs the right click function i want to write the code in VB.net but i am new to VB.net environment so i am having problem in coding it and i am also having problem to code double click event too .

I suspect you need to use p/invoke to simulate right clicks. I don't know that the framework lets you.
Your question the second tme is different to the first time. Also, why are you having problems with the double click event ? What bit is the problem?
farah mazhar wrote: but i am new to VB.net environment
Sounds like a classic case of someone picking up a compiler and trying to use it without learning how first. What are you trying to write that your first VB project needs to simulate right clicks across the entire system ?

I know. I was hoping when I saw your reply that you'd actually answered the questions I asked you.

I am trying to read a variable number of bytes from another .Net application but I can't ever get the whole message to read in properly. I have a string with ids and data values (id:value|id:value|...) that I convert to bytes before sending. I keep reading on forums that the standard way of reading a variable number of bytes is to add the number of bytes on the front of the message but I cannot find any examples of how to do that. I can add the length in bytes to the string but then I have to convert that to bytes to transmit so it doesnt seem to help. Am I missing something
Any help would be appreciated - I am on a time crunch

You said much, but nothing useful to diagnose the problem. We'd have to see the code the you're using to both send and receive the information. TCP?? So you've implemented a socket server and client in your app??
|
|
|
|

Here is my code
Sending code
Public Sub Send(ByVal dataToSend As String)
Try
bytesToSend() As Byte = System.Text.ASCIIEncoding.ASCII.GetBytes(dataToSend)
mysocket.Send(bytesToSend,0,bytesToSend.Length)
Catch se as SocketException
MsgBox(se.ToString)
End Try
End Sub
Receiving
Private Class StateClass
Public clientSocket As Socket
Public clientBuffer() As Byte ------> how do i know the buffer size before hand
End Sub
Public Sub OnAcceptConnection(ByVal result as IAsyncResult)
Dim state as New stateClass
Dim serverSocket As Socket = CType(result.AsyncState, Socket)
Try
state.clientSocket = serverSocet.EndAccept(result)
state.clientSocket.BeginReceive(state.clientBuffer,0,state.clientBuffer.Length,SocketFlags.None, _
New AsyncCallback(AddressOf ReceiveCallback,stateClass)
Catch acceptex as Exception
MsgBox(acceptex.ToString)
EndTry
EndSub
Private ReceiveCallback(ByVal result2 as IAsyncResult)
Try
Dim state As stateClass,CType(result2.AyncState,stateClass)
Dim numberBytesRead As Int32 = state.clientSocket.EndReceive(result2)
If numberBytesRead >0 Then
Dim receivedString As String = ASCII.GetString(state.clientBuffer)
Console.WriteLine(receivedString)
End If
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
