[ACAD 2013] MFC "An unsupported operation was attempted"

[Anonymous]

Hi everybody,

everything was working correctly, but

today I changed some controls in a MFC form and now when I execute the: 

CAcUiDialog::OnInitDialog();

I get a message: "An unsupported operation was attempted"

It seems that also others guys got the same problems and it should be a resources problem.

So I cheched for duplicates with the tool ResOrg and I tried to renumerate all the resources defines.

Then I removed all the macro in the DoDataExchange and the problem was solved, but just adding only a line it crach!!!:

void CNodeProperty::DoDataExchange (CDataExchange *pDX) {
		CAcUiDialog::DoDataExchange (pDX) ;

		DDX_Control(pDX, IDC_TXT_GAS, m_GasName);

		DDX_Text(pDX, IDC_NOME, m_Name);

 Any Ideas, Any tests to do?

It sounds like you already know that the problem is code not matching what is in the dialog resource. Make sure your resource macros are only defined in one place, then compare their values to what is in your .rc file. You'll have to change one or the other so they match.

Hi,

finally I restored a previouvs working version of the source code.

But why everytime I delete a control from the MCF form designer, it makes a mess with duplicate numbers?

Thanks
