Hi,

I am trying to use LIBCURLNET (thank you Jeff Phillips) in a C# Windows
Service Project but am experiencing difficulty.

Everything builds and installs great, but when I try to access it from a
Windows Service I get an exception fired "Unable to load DLL
(libcurl.dll)" logged in an event log, so my CURL operation never takes
place. I am perplexed, because the same code works fine from a Windows
application

I have set up a reference to libcurlnet.dll in the service project and
made sure that libcurl.dll is in the service install directory and even
stuck it in the windows/system32 directory.

I have also set my path to include a reference to /libcurlnet/bin/

I expected Libcurlnet.dll to work the same whether in a service project
or application project and I appear to be referencing it the same way.

I am a very new .NET developer. Is there any thing stupid I might be
omitting to do when building my Window Service, to make sure it can load
libcurl.dll?

Many thanks,

Anthony :)

Here is an example of my slightly modified EasyGet based on Jeff
Phillip's sample.

using SeasideResearch;

using SeasideResearch.LibCurlNet;

      class EasyGet

      {

            public static string strGetData;

            public static string strErrorMessage;

            public EasyGet()

            {

                  EasyGet.strErrorMessage = "";

            }

            public EasyGet(string strURL)

            {

                  try

                  {

                        EasyGet.strErrorMessage = "";

                        EasyGet.strGetData = "";

 
Curl.GlobalInit((int)CURLinitFlag.CURL_GLOBAL_ALL);

                        Easy oCurlOP = new Easy();

                        Easy.WriteFunction wf = new
Easy.WriteFunction(OnWriteData);

                        oCurlOP.SetOpt(CURLoption.CURLOPT_URL, strURL);

                        oCurlOP.SetOpt(CURLoption.CURLOPT_WRITEFUNCTION,
wf);

                        oCurlOP.Perform();

                        oCurlOP.Cleanup();

                        Curl.GlobalCleanup();

                  }

                  catch(Exception ex)

                  {

                        EasyGet.strErrorMessage = ex.Message;

                  }

            }

            public string GetTransferData()

            {

                  return EasyGet.strGetData;

            }

            public string GetTransferError()

            {

                  return EasyGet.strErrorMessage;

            }

            public static Int32 OnWriteData(Byte[] buf, Int32 size,
Int32 nmemb, Object extraData)

            {

                  EasyGet.strGetData =
System.Text.Encoding.UTF8.GetString(buf);

                  return size * nmemb;

            }

      }

This is how I use this object, to query a PHP file that returns database
results.

EasyGet oCurlOp = new EasyGet(PATH_IDMS + "getMachinePingData.php");
