Are you trying to add ToolBar to a CDialog?
If yes Check following articles
CToolbarDialog - dialog with floating toolbar[^]
http://www.codeguru.com/cpp/w-d/dislog/toolbarsandstatusbars/article.php/c1949/[^]
If that is not the case please ignore my message.

I hope it helps.

Im using Setwindowpos of one dialog in another class.

GetDlgItem() returns a handle to a sub item within a Dialog, not to a Dialog window. It is much better to do this in the Dialog itself, when you handle the WM_INITDIALOG message.

Hi,

I am an ISO file which run when I drag and drop on a shortcut of a .bat file.
The batch file call exe with some parameter.

I tried to run exe through ShellExecute with parameter but not able to run the full application.

How can I determine that what and how is happening when I drop ISO file over shortcut of batch file.

Try using ProcessExplorer[^] to figure out the exact command line parameters passed to the executable file that the batch file spawns. You might as well want to open and see the code within the batch file.

Hello again everyone,

I am posting this after a long night of research. Hopefully when I wake up I can begin to take whatever helpful information replied to this message and continue onwards.

My goal is to be able to read information from devices, and in this example my Network Interface Card.

I want to learn how to do this in C++ which is why I posted here instead of the Hardware and Devices section.

So what am I asking for? A good reference on where to start with reading information from hardware devices.

Once again thank you all in advance for pointing me in the right direction. This web site has been nothing but helpful to me and I learn something new every time I browse around.

You could find the MAC address by calling GetAdaptersInfo()[^]

Thanks for all to who responded. To answer your question, I am looking to retrieve any and all information if possible from any hardware device. This is a way for me to learn how to tap into the fingerprint of hardware devices such as (NIC)'s.

All for learning experience. I am taking a Networking class and want to make a simple program which can retrieve information from the (NIC) or entire network.

Depending on what kind of information about hardware you're looking for, you could always use WMI[^]

And what does that mean? The function doesn't succeed? In which case, have you tried checking the last error code by calling GetLastError() as the documentation states?

Yeah, so the error states why the function failed.

I'll favour the other poster here. Like he asked: is it the same computer or a different one? If it's a different one, is there an audio device and the board has a speaker? (Do you see the volume control icon on the tray area?)

I thought it were the same box which ran XP and the Server OS. I'll be shocked if they were different and one doesn't have a speaker. WTF | :WTF:

But how funnier can this it were the latter case. Smile | :)

It just sounded like something I'd do. I have a machine here that doesn't have external speakers, and the motherboard doesnt have one either, so it can't give the happy little beep when it boots. (Or any other time.)
