Is this a WTL/STL/ATL question?

Hi,

I am using

IHTMLElement3::fireEvent Method

in my display framework to fire my OnChange method to browser. Using script, I'm setting cancelchange status( window.event.ReturnValue = false; ). But "pfCancelled" argument of FireEvent is not returning cancel status "VARIANT_FALSE". Anybody knows the reason?

VS2010 CLR double to String, String to double methods

Are there any good examples for gui on C++ in VS2010 ?
Unsure | :~

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 ??

Re: VS2010 CLR double to String, String to double MSVC/C++ methods?

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.

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?

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");

}

There is a WTL section in CodeProject, I'd suggest you to look there.
In practice, you have to #include a few WTL headers in your STDAFX.H.
Take a look at Creating a WTL Dialog, Property Sheet or Wizard out of a resource (The Easy Way)[^], the sample project is an ATL DLL with WTL for the UI: the stdafx.h file will give you a hint.

Hope this helps,

Pablo.

Well I guess you need to iterate through the list from zero to the maximum value as indicated by the Count property.

i tried that as above...

C++

hr=pCon->Item(0,&ppContacts);

now ppContacts seems to be another interface with all COM predefined methods like Querry interface ,addref release etc.
