Try changing the order of include files as follows and check if it works #include "stdafx.h" #include "Windows.h" #include "WinUser.h"

complite your project as a windows application, there will be no console during it's executeing unless you AllocConsole when application need interactiving with user, FreeConsole when you want hide the console. Sorry for my English, I'm not good at it.

This above code works for binary image download, but the problem is: For an image file with 18k size, only 4k can be download and just half of the image can be seen on the client side. Any ideas? Thanks.

okk... thanks for ur reply...

I am able to connect to serial port but not able to read the data from the connected device. Here is the code which i am using to read the device- // Create the serial port with basic settings SerialPort port = new SerialPort("COM1", 9600, Parity.None, 8, StopBits.One); port.Handshake = System.IO.Ports.Handshake.None; port.ReadTimeout = 5000; port.Open(); //retrieve number of bytes in the buffer int bytes = port.BytesToRead; //create a byte array to hold the awaiting data byte[] comBuffer = new byte[bytes]; //read the data and store it port.Read(comBuffer, 0, bytes); string str; System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding(); str = enc.GetString(comBuffer); txtData.Text = str; port.Close(); when i am running this code then I get 0 in BytesToRead and comBuffer. I think i am doing something wrong but what it is not have any idea.

Well I figured out a way to do it, but it requires that you have the full version of Adobe installed on your PC so that you can gain access to the Adobe APIs (which doesn't technically qualify as a free way to do it). Here is the code I used to read the contents of a PDF. You will have to add a reference to the Adobe APIs in your project: Dim objPDFPage As AcroPDPage Dim objPDFDoc As New AcroPDDoc Dim objPDFAVDoc As AcroAVDoc Dim objAcroApp As AcroApp Dim objPDFRectTemp As Object Dim objPDFRect As New AcroRect Dim lngTextRangeCount As Long Dim objPDFTextSelection As AcroPDTextSelect Dim temptextcount As Long Dim strText As String Dim lngPageCount As Long Dim Fora As Long objPDFDoc.Open(tbdocdisplaypath.Text) lngPageCount = objPDFDoc.GetNumPages For Fora = 0 To lngPageCount - 1 objPDFPage = objPDFDoc.AcquirePage(Fora) objPDFRectTemp = objPDFPage.GetSize objPDFRect.Left = 0 objPDFRect.right = objPDFRectTemp.x objPDFRect.Top = objPDFRectTemp.y objPDFRect.bottom = 0 ' objPDFTextSelection = objPDFDoc.CreateTextSelect(lngPageCount, objPDFRect) objPDFTextSelection = objPDFDoc.CreateTextSelect(Fora, objPDFRect) ' Get The Text Of The Range temptextcount = objPDFTextSelection.GetNumText For lngTextRangeCount = 1 To objPDFTextSelection.GetNumText doctext = doctext & objPDFTextSelection.GetText(lngTextRangeCount - 1) Next doctext = doctext & vbCrLf Next doctype = "PDF" objPDFDoc.Close() --------------------------------------------- Alernatively, you can browse these links and try helping yourself http://www.componentsource.com/relevance/pdf/components/index.html?q=pdf+visual http://groups.google.com/group/microsoft.public.dotnet.languages.vb.data/browse\_thread/thread/99a3fbc1608f396e/236c45f7cf2713b5%23236c45f7cf2713b5
