Method to change default value from c#

[lokiys]

Title says it all...

Just basically a lot of times there is needed to save some value to use for next thread. By now I'm doing that with help of .txt file. Would be good to save some value for future use...

Thanks

Global variables?)

 

[lokiys]

Can you manage one and that same global variable from one and that same template ?

 

[rostonix]

What exactly do you mean

 

[lokiys]

As I know to set global variable and then change this variable you need at least two different templates.
Correct ?

i don't like use global variables
here is some example how to simulate global vars with linked table

string prefix = "in_"; //prefix of names for dumpable variables
string tablename = "dump"; //name of table

lock(SyncObject){lock(SyncObjects.TableSyncer){

    var table = project.Tables[tablename];

    //load data from table into variables
    for(int i=0; i<table.RowCount;i++){
        var row = table.GetRow(i).ToArray();
        if(project.Variables.Keys.Contains(row[0]) && row[0].StartsWith(prefix))
            if(!string.IsNullOrWhiteSpace(row[1]))
                project.Variables[row[0]].Value = row[1];
    }

    var varkeylist = project.Variables.Keys.Where(k=>k.StartsWith(prefix)).ToList();

    //make some manipulations with values and save them to next threads
    //in this example each value getting increased by 1
    table.Clear();
    varkeylist.ForEach(k=> {
        var newvalue = (int.Parse(project.Variables[k].Value)+1).ToString();
        table.AddRow(new List<string> {k, newvalue});
    });

}}

before run the snipet the in_ vars must have the default values in template or in the dump table

@LexxWork With this snippet you have to use files as well. Correct ? As I do not see any other way tables could be shared between threads...

What's a maximum size of an in-memory globally available table with that it works so-so?
I mean, is it ok to make a global table and work with it from within several threads when its size is several megabytes?
And what is an overhead for metadata for such a table. I mean, if I read a 1 MB csv file into a in-memory table, how much RAM will it take there?

 

[rostonix]

There's no in built limitations.
Size of table in memory is 2-3 times bigger than size of original file

Yes. This feature is a base for sharing local vars between threads.
