MaxStrLen Deprecated?

[f4n0]

Hi, I'm trying to resolve some CodeCop error but I'm stuck here: I was used to solving the error "Possible overflow assigning 'Text' to 'Code[128]'. (AL0139)" simply by adding a CopyStr(myVar,1,MaxStrLen(MyVar)). But today I found out this Warning message:

{
    "resource": "",
    "owner": "_generated_diagnostic_collection_name_#0",
    "code": "AL0141",
    "severity": 4,
    "message": "'MaxStrLen' is deprecated",
    "source": "AL",
    "startLineNumber": 55,
    "startColumn": 81,
    "endLineNumber": 55,
    "endColumn": 104
}

Assuming that I would not like to implement some hard-coded code (like CopyStr(myVar,1, MaxStrLen(50)) ) also to make my code easier to maintain, How can I fix that?

Thanks Stefano Primo

I leave an Update: I was watching my code where throws this warning and I saw this:

Now I'm a bit disappointing: If you watch carefully you will see the MaxStrLen that throws the warning and a few lines before there is also another MaxStrLen that does not throw any type of error/warning.

Hi @stefanoPrimo, The reason why you are getting an error on one and not the other is because the method has an overload. The first takes a text and the second a variant. The method that takes a variant results in a error being raised no matter what, so you need to change it to a text if you want to use that method.

Hi @thpeder, Thanks a lot, I didn't saw or knew that the MaxStrLen method could have an overload.
