GoToAssistant Remote Launcher - Build from sample c++ code

We are using GoToAssist for a support product. It is a window sharing application made by Citrix where we can remotely access a customers computer. When an end user wants support from us, we email them a generated url. They open this url in a web browser and the GoToAssist application is downloaded and run. There is the ability to launch a support session without having to open a web browser. This is done by building a c++ application where the webrequest and download is done automatically. The sample code is already made and available. We do not have the expertise to build it. We will pay you for creating the exe application which will take in as parameter the question (which is the access code). All other hardcoded strings will be provided. In the end, we will need a fully working exe. We prefer to have it built in Microsoft Visual Studio. We will also need documentation on how you got it setup and running in Microsoft Visual Studio. Here is the sample code: /* ****************************************************************** /* This app uses the strings defined to build a single URL and /* launches it, then handles the HTML response, then finally /* downloads the [login to view URL] and launches it. This is meant only /* as an example of how you might implement an automated, browserless /* launch of a GoToAssist session. /* /* This sample assumes that you are using the default SmartBox, /* where the only required field is the Question. /* /* Note that the values will need to be encoded for use in a URL /* more information about this can be found at the following URL. /* /* [login to view URL] /* /* And the RFC 1738 Standard for URL's /* /* [login to view URL] /* *************************************************************** */ /* /* Modification History /* Date | Who | Reason /* --------------------------------------------------------------------------------- /* 5/10/05 Ryan G.
