How to use OpenSharedParameterFile Method?

[Anonymous]

I spent whole afternoon trying to figure out how to use OpenSharedParameterFile Method...It seems easy, but when I debug the code, it always give me

"Error in readParamDatabase", it's internal exception..anybody know how to solve that?

Really drive me crazy!

Thanks for any reply..T T

Here is my code:

string fileName = @"C:\Users\Administrator\Desktop\revit\w1\try\" + datefromuser + ".txt";
FileStream fs = File.Create(fileName);

commandData.Application.Application.SharedParametersFilename = fileName;

try
{
SharedParameterFile = commandData.Application.Application.OpenSharedParameterFile();
}
catch (Autodesk.Revit.Exceptions.ApplicationException) { }

DefinitionGroup sharedParameterGroup = SharedParameterFile.Groups.Create("RevitParameters");

I want to create a new shared paramter file and try to add some shared parameter..

Hi

Could it be that file stream that is returned has "locked" the file for it self. At least File.Create documentation says this:

"The FileStream object created by this method has a default FileShare value of None; no other process or code can access the created file until the original file handle is closed."

Hope this helps.

Thanks for the answer, Finally I find the problem...it's because my shared parameter file is empty....T T..spend me so much time....

Hi,

I have a similar issue.

Does anyone know what could be causing this?

The Revit document already has a Shared Parameter file. I just wanted to use its parameters so I was trying to open it with the OpenSharedParameterFile method.

Many thanks.

The thing is, app is null because it is defined in the first method, while the open shared parameter file is in the second method:

So...seems to me that you have managed to figure out issues in your code. Or is there still something?

Seems to me, that you are new to C#. I would guess that you will face many similar issues, and probably the problem will not be the Revit API, but the programming environment in general. For those issues google & stackoverflow is your best friend. Detailed instructions to not Revit API specific issues aren't necessary provided here.

thanks @ollikat , I didn't realize at first it was a C# programming question. Do you have any suggestions on what keywords to search for on google?

It may be too late, but if anyone has a similar problem, please pay attention to the encoding used for the shared parameter file
