While it seems to be possible to declare arrays of complex object in
Origin C it is not possible to access them

Example :

Dataset DD[3];
DD[0].Attach("Data1_A");
DD[1].Attach("Data1_B");
DD[2].Attach("Data1_C");
(DD[0])[1] = j;
(DD[1])[2] = j;
(DD[2])[3] = j;

Compiles fine but
(DD[0])[1] = j;
results in a crash

it seems that the []operator is not fully implemented and not documented in Origin C

Can anyone help ?

Which version of Origin are you using? I tried the following code in Origin75 SR1, and it works fine


void tt()
{
	Worksheet wks = Project.ActiveLayer();
	
	Dataset dd[3];
	int ii;
	for(ii = 0; ii < 3; ii++)
	{
		dd[ii].Attach(wks, ii);
		dd[ii].SetSize(100);
	}
	
	for(ii =0; ii < 3; ii++)
	{
		for(int jj = 0; jj < 100; jj++)
			dd[ii][jj] = ii+ 0.1*jj;
	}
}

Perhaps the parenthesis are the problem. Should probably be this...

DD[0][1] = j;
DD[1][2] = j;
DD[2][3] = j;
