Dear Sir, I need to capture only decimal number in my TextBox field on my form, how can I control that ?

void OnKeyPress(System::Windows::Forms::KeyPressEventArgs^ e)override { if((e->KeyChar=='.')) { if(this->Text->Contains(".")) e->Handled = true; } if(!(wchar_t::IsDigit(e->KeyChar) || wchar_t::IsControl(e->KeyChar))) e->Handled = true; }

If I do this, I obtain what I need: void OnKeyPress(System::Windows::Forms::KeyPressEventArgs^ e)override { if(!(wchar_t::IsDigit(e->KeyChar) || wchar_t::IsControl(e->KeyChar) ||(e->KeyChar=='.'))) e->Handled = true; } Thanks for you support
