Returning a string to Navision, from a COM

ombacke · 2005-10-05

I return from a cmethod in my dll a string, when I call that method form navisiom and try to put the return value in a Navision Text[1024] variable, it tell me that the string size is too big for the buffer size.. But the string return by my method is just 339 characters long.. Why is that?

It's not your string size, but the Navision executable wrapper that is the intermediate between the COM and your text string that is 250 characters long. You can't do much about that.

Is it the same with Navision 4.0?

I don't know I haven't tried it.

no solution in sight? I've got the same problem with Navision 4.0 :roll:

try to change the method to return stream or an object or change your method to return 250 characters at a time. So call it like this

while com.mymethod(var str) do begin
1024string := 1024string + str;
end;
