Frequently Asked Questions (Visual Studio .NET)

Problem: Demo for DSP Master .NET can not be recompiled. 
Solution: Trial version for Dew Lab Studio has three demo applications. DSP Master Demo for VS.NET can only be recompiled with the registered version of TeeChart 2010.NET. The registered version of DSP Master includes source code for TeeChart related assemblies and these assemblies can be built with TeeChart.NET v2, v3 and 2010. To rebuild the demo with arbitrary TeeChart version the Dew.Math.TeePro.dll and Dew.Signal.Tee.dll have to be recreated with references updated for the desired TeeChart version.

Problem: Dew DSP Master does not show component editors at design time, or popup menu shows the Edit command, but nothing happens when clicked. 
Solution: Dew.Signal.Editors.dll, Dew.Math.Controls.dll, Dew.Math.dll, Dew.Math.TeePro have to be included in the list of referenced assemblies and path to assemblies have to be added to the assemblies search path in the project settings. The changes then need to be saved and project reopened.

Problem (25th March 2010): MtxVec v3.52 when compiled with TeeChart Pro in Delphi 2009 and later gives a message that a TeeChart file needs to be recompiled. 
Solution: There are TeeChart files left over in the debug dcu search path (like: C:\Program Files (x86)\CodeGear\RAD Studio\6.0\lib\debug) after TeeChart installation. Delete those or disable compile with debug dcu's in the compiler settings. The files start with "Tee".

Problem: Changing Vector.Length or TVec.Length does not preserve vector contents.
Solution: This is the most frequent error of new users. To preserve the contents of the vector when resizing call TVec.Resize(..).
