I dont know how to do what you are asking for, but there is one solution though.
instead of deriving the class you can make a member variable of baseclass, then initialise the iodevice and then initialise the baseclass with the device.
Kinda wrapper to the baseclass.

Hi !
I thought about the wrapper, but then I would have to reimplement in my class each public method of the class I would wrap, and then just forwarding the call to a method from my wrapper to the wrapped class. I wanted to avoid that by subclassing....
Well, I guess there is no other solution !
Thanks for the help !

Your base class does not accept uninitialised device rite, that means the device is first initialised and then passed to the baseclass, you need to do the same with ur derived the class too.

You should think about inventing language "D"
What if this device wont open? (Big sh*t)
I recommand open it before constructing "Baseclass". Use the F11 button to step in...

Then in the future we will have D#

I think that the base class is badly designed. If you need to a opened IODevice in BaseClass constructor, why can't you open the device just inside the BaseClass constructor?

I agree with you but sadly, I don't have access to the source of the base class....I have to deal with it as it is !!!

The piggy solution could be:
1. write a simple wrapper to IODevice
IODevice IODeviceWrapper(IODevice& iod)
{
iod.open();
return *iod;
}
2. call a constructor
CMyClass::CMyClass(IODevice iod) : CBaseClass(IODeviceWrapper(MyIODevice))
{
...
}
I know, it's not elegant, but what can you do with botched class without source code?
(Answer: use a open-source classes, for example from CodeProject  )

You can't, that's how the language works. To do what you want, add a separate Init() method and do your initialization work there, instead of the ctors.

Can anyone help me connect to a database ( an .mdf) and modify it and stuff without using a DSN? I'm not sure why this program that I'm trying to interface with doesn't use a DSN, but it doesn't seem to. Should I create my own DSN in order to access it? Any ideas would be helpful.

Check the specs for the ODBC driver you're using. The access driver, for instance, allows DSN-less connections via ODBC by specifying the DBQ=database-path-to-file
and Driver={Microsoft Access (*.mdb} connection substrings, in addition to any others you might want.
Generally you need to provide at least the driver name, and the path to the data for 'local' (non-server) access.

Thank you very much for you response, but can you please give me a little more in-depth syntax on how to do this? Maybe an example? Thanks again.

Hi
I want to be able to send a minimise message to a window, so the window minimises. (When that happens, it'll be added in the system tray .. that code already works.)
Greetings,
Jens
|
|
|
|
|
SendMessage(<windowhandle>,WM_MINIMIZE,0,0);
To get the window handle use FindWindow() or if its from the application itself u are sending the message u can access it directly.
|
|
|
|
|
WM_MINIMIZE: undeclared identifier.
Normally, it is the CFrameWnd which needs to be closed.
In my App class it is constructed and show:
m_pFrame = new CMainFrame;
m_pFrame->ShowWindow(SW_SHOW);
m_pFrame->UpdateWindow();
//Send MINIMISE message.
SendMessage(m_pFrame->m_hWnd,SW_MINIMIZE,0,0);
Doesn't work neither :x
|
|
|
|
|
how about
ShowWindow(SW_SHOWMINIMIZED);
??

Are you through with the logic of debugging a exe file ??? if not that is of high priority.
this problem is only the tip of the iceberg.
