Getting output type before using OutputGetStringValue, OutputGetRealValue

[Cody_Godines]

Hi, I am using the API, and have a working code.  However, for generality, when getting output results I cannot tell what type is it.  For example, if I use 

....

Outputs = WS.Outputs

For i = 0 To WS.Outputs.Count - 2
var = Outputs.GetAliasByIndex(i)

varval = WS.OutputGetRealValue(var)
varvalstr = WS.OutputGetRealValue(var).RealResult.ToString
varunitstr = varval.Units

imsg = imsg + "Index=" + Str(i) + " , Name= " + var.ToString + " , Value= " + varvalstr + " , Units= " + varunitstr + vbCrLf
Next

...

How can I tell before calling OutputGetRealValue that my output is a real number not a string or matrix?

Hi,

Examine the following code snippet located in attached text file.:

How to tell if value is a string, scalar, or matrix.

Hi terryhendicott,

I was able to follow your snippet, modify, and it worked for the real and string. Thank you for taking the time to answer me.  I appologize i did not know it was answered until this week.

The part of the matrix, I was left with this,

hereResult = WS.OutputGetMatrixValueAs(WS.Outputs.GetAliasByIndex(a), "")
rowCount = hereResult.MatrixResult.Rows
colCount = hereResult.MatrixResult.Columns
Dim Start As String
Start = "L7"
For inrow = 0 To rowCount - 1
For incol = 0 To colCount - 1
Dim b As Integer
b = hereResult.MatrixResult.GetMatrixElement(inrow, incol, dblhere)
Debug.Print(b)
'Worksheets(WorksheetName).Range("L7:L7").Offset(inrow, incol).Value = dblhere
Next incol
Next inrow

I am trying to test it but cannot seem to set a matrix as an output variable in mathcad prime 9.  I've tried tables and matrices.  Also, how do i know the matrix item will be a double value?

Much appreciated!

Hi,

The good news

There are four equals signs in mathcad.  The assignment equals which is acolon and an equals sign, the comparison equals which is a bold equals sign, the global equals sign that is three horizontal short lines, and the one that concerns us the display equals sign that is an equals sign.  to get a matrix as an output value use the equals sign to display the matrix, select all of this equation and then use menu Input/Output | Integration | Assign Outputs

The bad news

The API does not work for matrices that contain any element is a string, nested matrix, or complex variable.  The API assumes all matrices have real numbers only hence no methods to check this assumption.

HI terry, I thought i had this working and now i cannot get a simple test file working.  Do you think you can send an mcad that would work with this?  With one matrix like you say.  Maybe complete the snippet.  Please.
