Subject:
How to build LanScape VOIP Media Engine software examples using Visual Studio .NET 2003 or greater.
Summary:
Since the release of Visual C++ 6.x, there have been substantial changes to Microsoft development tools and associated libraries. The most noticeable changes have come in the form of new MFC 7 libraries and the standard runtime libraries.
Unfortunately for developers having to work in both VC++ 6.x and .NET, the newer runtime libraries and MFC 7 are not fully backward compatible with version 6 runtime or MFC 6 libraries.
This means that a few of the VOIP software samples that are shipped with the LanScape VOIP Media Engine will not by default link properly using the newer MFC 7 libraries used by .NET. The problem is that the spectrum analyzer and DTMF static libraries that are shipped with the VOIP Media Engine were built using VC++ 6 standard runtime libraries and MFC 6. The version 6 libraries used by VC++ 6.x cannot be mixed with the standard libraries and MFC 7 libraries used by .NET 2003 or greater.
Solution:
You must obtain updated spectrum analyzer and DTMF libraries from LanScape. To properly build the LanScape VOIP Media Engine software examples using Visual Studio .NET 2003 or greater, please follow the following steps:
1)
Download updated spectrum analyzer and DTMF libraries located at:
http://www.lanscapecorp.com/Binary/MFC7_Libs.zip
2)
Unarchive the above image and place the new LanScape libraries from this image in your example software’s “Software Examples\Lib\xxxxx” directories. The “xxxxx” part of the path will be Debug and Release.
3)
Convert the existing Visual Studio 6 workspace/project files to .NET solutions. Do this by opening the “Software Examples \BuildAll.dsw” workspace file using Visual Studio .NET. Visual Studio .NET will tell you that the files need to be converted to a new format. Specify “Yes” or “Yes for all” depending on the version of .NET you are using. At this point your project files have been converted.
4)
Edit Link project settings for all projects that link to the DTMF.lib and Spectrum.lib libraries. Change the names to DTMF_MFC7.lib and Spectrum_MFC7.lib respectively.
5)
Optional: Microsoft had deprecated the procedures Enable3dControls() and Enable3dControlsStatic(). Search your example source code and comment out these procedure calls. They only exist in each of the samples CMainAppClass::InitInstance() member functions.
6)
Rebuild all of your example applications. You should have no compile/link errors or warnings.

It would be nice if windows files were supplied with a .zip extension. Then we wouldnt have to hunt round for some rar software. We could just use Windows to unzip the files !

Thanks for your comments. We are always looking for ways to make things easier for our customers. We use rar because we generally get 20% better compression rates and we have come to like it much better than the zip format. We suggest you look into WinRar software. Its very inexpensive and sooner or later, you are going to need it.
The library archive has been changed from rar to zip file format.
