Second post that I see with class names similar to Turbo Pascal's Turbo Vision, and now I think why: Embarcadero bought Borland's products some time ago.
As for your problem: I guess edtNume_elev->Text returns a Unicode string, and you are trying to store that in a char array; it at least should be an array of wchar_t. I also don't think you can do what you are doing: You cannot change the "value" of nume by assigning Text to it. You most likely need to copy the string using strncpy(), or most appropriately, wcsncpy() for wide char strings.
As for the use of Admini, I am not sure what you want to accomplish. If it is an output file stream, shouldn't you use operator<< instead?
And please use [code]//Paste code here. [/code] tags to show code.
Of course same errors. That is not the only modification that you need to use. I told you you cannot just set the Text property to nume. I told you that you needed to copy it using wcsncpy(). Have you tried copying it?
As for Admini, have you tried using operator<< instead?? Show your updated code to see how much you have advanced so far.
By the way, if Text returns a pointer, and if you are not changing the text, you could just receive the pointer like this:
