VS2010 CLR double to String, String to double methods to get data in and out of editText Textboxes in MSVC / VCpp? Are there any good examples for gui on C++ in VS2010 ? :~

See here[^] for
Double.ToString(), and here[^] for the reverse operation.Unrequited desire is character building. OriginalGriff I'm sitting here giving you a standing ovation - Len Goodman

Richard, Are there good gui examples for VS2010 C++ for CLR and MFC anywhere? Not even sure if there is a better flavor of gui beyond those...ATL ??
Follow the links I gave you and read the explanations and sample code. You also need to decide whether you are using CLR or MFC; they are not the same.

Richard Yes, trying to use CLR this time. Would be interested in finding good gui examples for MFC or CLR though. Not even sure about ATL..... Is there a best way to do gui with C++ VS2010?

//How to do conversions for CLR C++ GUI //This worked double dblInput1 = 0.0; double dblInput2 = 0.0; double dblAnswer = 0.0; String ^ strInput1; String ^ strInput2; strInput1 = this->Input1textBox->Text; strInput2 = this->Input2textBox->Text; Double::TryParse(strInput1, dblInput1); Double::TryParse(strInput2, dblInput2); dblAnswer = dblInput1 + dblInput2; Answer1textBox->Text = System::Convert::ToString( dblAnswer ); But, How do i add an If then to handle the TryParse exception???

Here is the conversion part CLR isnt too bad... better than MFC yes? //How to do conversions for CLR C++ GUI double dblInput1 = 0.0; double dblInput2 = 0.0; double dblAnswer = 0.0; String ^ strInput1; String ^ strInput2; strInput1 = this->Input1textBox->Text; strInput2 = this->Input2textBox->Text; if (Double::TryParse(strInput1, dblInput1) & Double::TryParse(strInput2, dblInput2)) { // do something dblAnswer = dblInput1 + dblInput2; Answer1textBox->Text = System::Convert::ToString( dblAnswer ); } else { // the text was not a number, show user an error if appropiate MessageBox::Show("Error"); }

That looks OK.
