| Код | unit Unit1; {MathCad Automation Controller OLE Automation Controller example for MathCad Requires: MathCad 7.02 or later. Two MathCad doc's named TEST1.MCS and Test2.MCD, with out0 out1 and out2 vars computed from in0 in1 in2. All of them are complex numbers.
Instructions: 1.- Uses Unit OLE2, where OLE constants such as VT_Dispatch=9 are defined. Also uses other OLE units (see Uses clause):
2.- Define variables of Variant type in the VAR section VAR MCadObject, in0Re, in0Im, outRe0, outIm0, in1Re, in1Im, outRe1, outIm1, in2Re, in2Im, outRe2, outIm2 : Variant;
3.- MathCad object can be inserted in the OLE container interactively or by program by sending the TOleContainer message : CreateObjectFromFile(const FileName: string; Iconic: Boolean) with FileName = FullPathName of MathCad file and Iconic = False, to display the file contents and not the icon. oleContainer1.CreateObjectFromFile('c:\TestDir\Test1.mcd',False);
4.- The MathCad object can be interactively activated by Double Clicking on it or by program by setting to aaManual the TOleContainer property AutoActivate oleContainer1.AutoActivate = aaManual and executing the verb oleContainer1.DoVerb(ovShow) to display the object. Another way of doing this is by executing oleContainer1.DoVerb(ovPrimary)
5.- Asign the object in OleContainer to a Variant type var; MCadObject := OleContainer1.OleObject;
6.- Check that the object returned is of VT_DISPATCH type (9) If VarType(McadObject) = VT_DISPATCH then label1.Caption := 'OK: Type returned VT_DISPATCH' Else Label1.Caption := 'Error: Type returned ' + IntToStr(VarType(MCadObject));
7.- Set the values of input vars and send the messages to pass input vars, recalculate the doc and retrieve the out vars. SetComplex( varName, realPart, imagPart) Recalculate GetComplex( varName, realPart, imagPart) to MCad object. Display the values of the output vars. }
