QUOTE (Wendy L @ Nov 1 2008, 03:56 AM) Hi And thanks for the answers. I have been told that it is possible to include the .h files from Labview and then use these files to do the drawing of the graph. I have also solved the linker problem. But now I get a -10 error when I try to use PlotWaveform. Could you please have a look at my code: #include "stdafx.h" #include <stdio.h> #include <winsock2.h> #include <stdlib.h> #include <utility.h> #include <ansi_c.h> #include <cvirte.h> #include <userint.h> if (InitCVIRTE (0, 0,0)==0) return -1; //Out of memory int panelHandle = NewPanel(parentPanel,"Graph",top,left,height,with); printf("panelHandle: %d\n",panelHandle); int nNewCtrl = NewCtrl(panelHandle,CTRL_NUMERIC,0,10,10); printf("nNewCtrl: %d\n",nNewCtrl); DisplayPanel (panelHandle); int PlotWaveform_RETURN_VALUE = PlotWaveform (panelHandle, nNewCtrl, myArray,4,VAL_DOUBLE,1.0,0.0,0.0,1.0,VAL_FAT_LINE,VAL_DOTTED_SOLID_SQUARE,VAL_SOLID,1,VAL_RED); printf("PlotWaveform_RETURN_VALUE: %d\n",PlotWaveform_RETURN_VALUE); RefreshGraph (panelHandle, nNewCtrl); The result when I run the program is the following: panelHandle: 1 nNewCtrl: 2 PlotWaveform_RETURN_VALUE: -10 What is the problem with the PlotWaveform function, what does the -10 error indicate?

Hi I want to use the following Labview/CVI commando: PlotWaveform in Visual Studio 2008. I have included the following files: #include "stdafx.h" #include <stdio.h> #include <winsock2.h> #include <stdlib.h> #include <utility.h> #include <ansi_c.h> #include <cvirte.h> #include <userint.h> I have linked to the following Labview DLL files: WS2_32.lib labview.lib lvsb.lib I have the following relevant commands in my project: //Setup CVI if (InitCVIRTE (0, 0,0)==0) return -1; //Out of memory // Plot waveform PlotWaveform (panelHandle, PANEL_GRAPH, waveformPtr, numberofpoints, VAL_DOUBLE, 1.0,0.0,InitialX, XInitial,VAL_THIN_LINE,VAL_NO_POINT, VAL_SOLID, 1, VAL_BLUE); // Refresh graph now RefreshGraph (panelHandle, PANEL_GRAPH); But I get the follownig error: Error 1 error LNK2001: unresolved external symbol _InitCVIRTEEx@12 Error 2 error LNK2001: unresolved external symbol _PlotWaveform@72 Error 3 error LNK2001: unresolved external symbol _RefreshGraph@8 I don´t understand the error, could it bee a linker problem? Does anyone understand the errors? Or do you have a guide for how you use Labview commands in Visual Studio? I have used the following guide: http://www.ni.com/pdf/manuals/370109b.pdf But I ended up with the errors I explained. BR Benjamin
