.NET Open Clients

Setting up a parameter array

You must place all parameters for a procedure (external, persistent, and internal) or user-defined function into a Progress.Open4GL.Proxy.ParamArray object before running the procedure or user-defined function.

Creating a parameter array

You can create a ParamArray using the following constructor:

Syntax

public ParamArray (int numParams)

numParams

Specifies the total number of parameters (including all INPUT, INPUT-OUTPUT, and OUTPUT parameters).

You can add each parameter to the ParamArray using a set of methods that add a parameter based on the data type of the parameter or a single generic add parameter method. You must identify the parameter position as well as the mode of the parameter. For temp-tables and ProDataSets, you must identify the meta data. You must also pass in an initial value for input and input-output parameters.

If you want to reuse the ParamArray for another call:

The number of parameters for the next call must match the number of parameters in the ParamArray object.
You must clear any current values in the ParamArray using the Clear() method, as shown:

// Create the ParamArray ParamArray parms = new ParamArray(1); . . . // Clear for reuse parms.Clear();
