Hi,
I have a C++ dll with a header having the following struct:
struct TData
{
DWORD m_Command;
BYTE m_Option;
char m_Message[300];
};The dll also has a callback function MessageReceived that takes TData as a parameter. The function fills in the m_Message with some data and returns.
in VB6, I have a similar type:
Public Type TData
m_Command As Long
m_Option As Byte
m_Message As String
End Typewhen the MessageReceived is called, I have an error:
The instruction at ........ referenced memory at ........ The memory could not be "written"
I'm assuming that this is because I'm not initializing a buffer for m_Message. Is there a way I can do this, since the MessageReceived is a callback, I do not create my TData to pass it in the function. Help.
