成功返回TRUE.
例如: VB,在命令中,调用绘矩形命令函数,并得到绘制的矩形id.,该代码在命令事件中执行。
Dim param As MxDrawResbuf
Set param = New MxDrawResbuf
param.AddString "Mx_Rectang"
'是绘制矩形的线宽.这是命令参数。
param.AddDouble 10
MxDrawX1.CallEx "Mx_SendStringToExecuteFun", param
'得到绘制的矩形id.
Dim retparam As MxDrawResbuf
Set retparam = MxDrawX1.Call("Mx_GetEntitysLastCmd", "")
Dim i As Integer
i = 1
Do While i < retparam.Count
MsgBox retparam.AtLong(i)
i = i + 1
Loop
