can any one please solve my issue? I am creating a step type in Labwindows. I want to set required type of an expression control as array of type 'Protocol' 'Protocol' is a type which I have already specified in TestStand I have initialised the variable 'ReqnamedTypes' as char *ReqnamedTypes[1] = {"Protocol"}; I am using below two functions after loading and before poping up the panel in the same order TS_ExprCtrl_SetRequiredTypes (Lvi_pHandleEEP, PANEL_EEP2_BUFFER_ARRAY, TSUIConst_ValidExpressionType_NamedTypeArray)); TS_ExprCtrl_GetRequiredNamedTypeArrays (Lvi_pHandleEEP, PANEL_EEP2_BUFFER_ARRAY, ReqnamedTypes, 1); but in TestStand when I select a variable of Array of type 'Protocol' it is giving an evaluation error as "Expected <No type specified>, found Protocol" why it is not able to set the required Array of named type for the expression control, am I doing any mistake? I am using Labwindows 7.1, and TestStand 3.1 Thanks in advance. |
