Friends,

How to I resolve the AccessViolationException Error calling VFP DLL in C# VS2010? The test VFP DLL and test C# app works fine in VS2005, but not in VS2010

VFP8

DEFINE CLASS Functions AS Custom OLEPUBLIC
FUNCTION Test(lnInt as Integer) as Boolean
RETURN .T.
ENDFUNC
ENDDEFINE

C# VS2010

private void button1_Click(object sender, EventArgs e)
{
bool result;
testdll.Functions test = new testdll.Functions();
result = test.Test(99);
if (result == true) MessageBox.Show("Returned True"); else MessageBox.Show("Returned False");

}

Error on statement : result = test.Test(99); AccessViolationException was unhandled. Attempted to read or write protected memory.

Note : Set Platform target to x86. Target framework was set to 2.0 by migration wizart. Checked Allow unsafe code.

Thanks!!!!!!

Ellis
