Как изменить в label свойство text?
требуется чтобы в label выводилось число увеличенное на 1
вот моя мысль, но она не работает
Код:
private: System::Void button_account_Click(System::Object^ sender, System::EventArgs^ e) {
i++;
this->label_num->Text = IntToChar(i);
}
|
Ну к примеру так:
Edit1.text := IntToStr(StrToInt(Edit1.text)+1);
Или так:
Edit1.text := StrToInt(IntToStr(Edit1.text)+1);
(На "C" перевести не сложно.)

мне надо не в String а в String^
Код:
private: System::Void button_account_Click(System::Object^ sender, System::EventArgs^ e)
{
i++;
char myString;
myString = (char)i;
String ^ myManagedString = Marshal::PtrToStringAnsi((IntPtr) (char*) myString);
this->label_num->Text = myManagedString;
}
теперь ошибка при конвертации int в char
исполльзовал itoa() для преобразования таже ошибка |

Выводите его как текст, всё равно свойство Caption текстовое. Самый простой способ.
Код:
//---------------------------------------------------------------------------
void __fastcall TForm1::Button1Click(TObject *Sender)
{
for(int i = 0; i <= 100; i++)
Label1->Caption = i;
}
//---------------------------------------------------------------------------

в VC++ нет у label такого свойства
я в принципе нашел примитивное решение

i++;

Как нет? В Visual C++ нет? Что-то мне мало верится. Это свойство класса, а не редактора кода
 |
котвася если i объявлено как класс System::Int32 то у него есть метод ToString (унаследован от класса Object).
Соответственно
Код:
System::Int32 i;
//...
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
i++;
this -> label1 -> Text = i.ToString();
}

А какое есть?
Нужно свойство в VC++ будет иметь тип CString (стандартный класс строковых объектов)
А все эти char* забудь, как кошмарный сон. Ибо для использования указателей такого типа нужно чётко понимать, какая команда что делает.
В частности, выполнение такого кода будет абсолютно непредсказуемо

простое решение нашел на С#+Silverlight. Решено.

котвася, Silverlight для решения подобной задачи - стрельба из пушки по воробьям :) Достаточно просто C# с первым фреймворком :)
