Hi all, I’m new to Open AT. 😕 My goal is to develop an application on Visual [Basic.NET](http://Basic.NET) which will use wavecom library to send out SMS through Wavecom FASTTrack. I’m not sure it can be done in Visual [Basic.NET](http://Basic.NET) or not. So, I’ve installed the Wavecom Open AT. I’m trying to run the sample application through the Open AT Project Wizard. However, i get this Error “Unable to run the wmnew script; Open-AT or Cygwin may not be correctly installed.” My 2 questions are: 1. How do i proceed from the error “Unable to run the wmnew script; Open-AT or Cygwin may not be correctly installed.”? When i did the installation, it was indicated that the Cygwin has already been installed with the \* mark. 2. How do i add a reference to the wavecom library in Visual [Basic.NET](http://Basic.NET). What file(s) do i need to look for? Thanks. swlim ---

Hi swlim, You just can develop your application on following environments: - Eclipse - Visual C++ 6.0 - Visual C++ .NET 2002 or 2003 –\> Visual [Basic.NET](http://Basic.NET) can not use as the development environment for OpenAT. With Visual C++, .NET, you must install these program before install OpenAT. Hope can help you. ttt ---

hi trthaithong, thanks for the reply. does it support visual c++ 2005 or only up to visual c++ 2003? Because before i installed Open AT, i already had Visual Studio 2005 installed. so, the error due to the fact that i do not have visual c++ 6/2002/2003 installed? many thanks. swlim ---

You don’t need Open-AT for that at all! > [@](#): > > I’m not sure it can be done in Visual [Basic.NET](http://Basic.NET) or not. I’m sure it can - all you need to do is to send the appropriate AT Commands to the modem through a COM port. > [@](#): > > So, I’ve installed the Wavecom Open AT. Again, there is no need for that. Open-AT is for writing applications to run inside the modem itself - you don’t need this. You have a PC, and your application will run on the PC - you don’t need any intelligence in the modem. In fact, you should consider whether you need a modem at all - there are plenty of services available for sending & receiving SMS without the need of any GSM modem… For example: [dialogue.co.uk/what\_we\_do/mo … messaging/](http://www.dialogue.co.uk/what_we_do/mobile_corporate_messaging/) ---

Thanks awneil. Appreciate it. I can actually start work now. 🙂 Btw, do you happen to know of any sample [VB.net](http://VB.net) 2005/2008 codes to send the appropriate AT Commands to the modem through a COM port? ---

I don’t but, as far as [VB.net](http://VB.net) 2005/2008 is concerned, it’s just a matter of sending text to a COM port, and receiving text back from a COM port - so you really just need to look for standard COM port examples… You could try: [codesearch.google.com](http://codesearch.google.com) [codeproject.com](http://www.codeproject.com) [msdn.microsoft.com](http://msdn.microsoft.com) [codeguru.com/](http://www.codeguru.com/) [developer.com/](http://www.developer.com/) etc…
