Modify A Global Variable Value (C#)

Jason Taylor Feb 7, 2016 8:48 PM

I am trying to modify global variables within my C# code.

Based on these two examples:
Re: Macro change global variable

2015 SOLIDWORKS API Help - Add and Modify Equations Example (C#)

I have come up with the following code, but it doesn't change the global variables. Also, when I go into the equation manager after the code runs it has red Xs by the equations and says "The syntax of this equation is incorrect".

string Depth = "\"Depth\" = " + param["Part"].Substring(0, param["Part"].IndexOf("x"));

string flangeWidth = "\"FlangeWidth\" = " + param["Width"];

swEquationMgr = swModel.GetEquationMgr();

swEquationMgr.SetEquationAndConfigurationOption(0, Depth, (int)swInConfigurationOpts_e.swAllConfiguration, null);

swEquationMgr.SetEquationAndConfigurationOption(0, flangeWidth, (int)swInConfigurationOpts_e.swAllConfiguration, null);

NOTE: The Depth variable correctly evaluates to ("Depth" = 8) & flangeWidth evaluates to ("FlangeWidth" = 3.5).

Can anyone help me with what I am doing wrong?

Hi,

Make sure that you are using the correct decimal point. Try to set your param["Width"] to integer (e.g. 5) and see how it goes. What is the value inside param["Width"] and what is the type of the value?

Thanks,
Artem

  param["Width"] = 3.5 and is a string value. I left it at string because both examples I was basing off of had the full equation in doubles quotes which makes it a string and the popup tip I get in visual studio tells me that part of the SetEquationAndConfigurationOption method requires the equation in string format.

    Try param["Width"] = 3,5 (comma instead of dot)> What is you decimal symbol set in control panel?

      How did you get to that "Customize Format" dialog?

        Go to Start in the Windows then Control Panel->Region and Language

        My decimal format settings are correct. I'm thinking the problem may have to do with the issue referenced in these posts:
        Equations broken in SW 2015 SP4
        SOLIDWORKS KB3072630 Update Issues
        
        I attempted to repair my installation and it fixed the broken equations when I reopened the part, but they "re-broke" after I edited them.
        
        I found a workaround to updating the value of the equation, by adding a construction geometry line segment and setting the global variable equal to that dimension. Then, I just update the length of the line segment. However, this still doesn't help with the recurring syntax error I'm getting
