Thanks for the reply,
I am thinking of getting the CWnd rect and using it as a place holder for other forms.

Is there a real simple way to disable a toolbar item programmically. I am trying CCmdUI however it doesn't seem to be working. The one difference here is that the toolbar I am working with in trying to enable and disable items is on a separate toolbar, not the mainframe or document toolbar.
Thanks!

Try this:
m_wndToolBar.GetToolBarCtrl().SetState(IDC_TOOLBARBUTTON1,~(TBSTATE_ENABLED))
here m_wndToolBar is the variable for that Toolbar and IDC_TOOLBARBUTTON1 is Button's ID.

thanks! Actually did figure out my issues. The resource ID's did not match any of the event ID if you know what I mean so they were all greyed out. This information you give here, though, I still may need. Thanks for the tip!

hi everyone..
i'm having this stupid problem that i don't know how to solve:
DWORD Size = GetFileSize(..);
int Arr[Size];
the problem is that Arr doesn't accept Size to be the number of elements!!!

I don't think arrays like to be dymically allocated. I think you have to give it a constant number.
Try using CStringArray instead.
Hope this helps.

int *pArr = new int[Size];

Not sure in C++ (yet anyways) but in VB there is a keyword to resize the array and to save the info in the array.

Hello, I hope someone can help me here. I've been working on a project that allows me to inject data into the stream of keyboard and mouse devices. So far I have, I believe, succesfully called DefineDosDevice and CreateFile to open HANDLE's to the mouse and keyboard.
However, I am now stuck because I cannot find any documentation or information on how to use DeviceIoControl in the way I want to. MSDN only documents the use of disk geometry stuff, which isn't what I want.
As I understand it, now that I have the handle for the mouse, I should be able to call DeviceIoControl. I am not sure on the arguments, so here's what I know:
DeviceIoControl(m_hMouse,
CTL_CODE(
FILE_DEVICE_MOUSE,
0x802,
METHOD_BUFFERED, FILE_ANY_ACCESS),
NULL, 0,
NULL, 0,
NULL, NULL)
So, based on this, can anyone explain to me, at the very least, what arguments to send DeviceIoControl to control mouse clicks and movement?
Thanks, much appreciated.

Not to divert you form your endeavors, but you should also examine the function "keybd_event" and the "Raw Input" section of MSDN. They might help you out too.

Thank you, but they were unsuccessful.
As it turns out, I figured out what I needed to do. I rewrote new mouclass.sys and kbdclass.sys drivers. The need to access low level input was required, keybd_event and SendInput were insufficient, and they communicate on too high of a level, with windows messages.
Anyway, my new drivers work great, DeviceIoControl can control the mouse as it if were physically being moved. Wasn't a fun ride, but it works.
Thanks for your reply anyway.

Hi,
Just wondering if anyone can point me to a C++ function or run-time library call that I can use to create a new folder like this:
NewFolder("C:\\Engineering Data\\Diagnostic Data\\2004_10_15");
I did find SHFileOperations but that seems to be used for deleting, renaming or moving files. I just need to create a new folder under an already existing folder. The higher folder "Diagnostic Data" as used above will always exist if that matters.
Thanks,
Robert

CreateDirectory("C:\\Engineering Data\\Diagnostic Data\\2004_10_15") will fail if "C:\\Engineering Data\\Diagnostic Data\\" does not exist.

Correct but did you read the initial post?

Hi,
I hope someone could help me with this because i'm totally stuck.
The problem i have is an application that locks my cdrom drive so it can not read data cd's.
I have used a program called API spy to figure out how the drive is locked. It calls the function "DeviceIoControl" with dwControlCode 0x24014 and 0x24028 which is functions IOCTL_CDROM_GET_VOLUME and IOCTL_CDROM_SET_VOLUME.
After this the drive is locked, i have tried to unlock it by calling IOCTL_CDROM_SET_VOLUME and revert to the original values but the drive is still locked.
The drive remains locked until the process that locked it terminates.
Any help appreciated!

If you know the name of the program that is locking the drive, why not just terminate it, and possibly remove it from your machine?

I need that program up and running it does other thing besides locking my cd.
It's a comercial presentation software, i don't know why but their runtime component locks the cd or sets it in a CD Audio only mode.

Your problem is the application has told Windows that it is the only thing that should be allowed to use the drive. Windows obeys this, like it should.
Call your vender and see if there is soemthing you can do. The DeviceIoControl function call has nothing to do with it, it is the open call.

I have tried to reach the Vendor but they have not responded, yet.
I tried to create an application that used the same DeviceIo calls that the comercial app and that locks the drive in the same way so it seems like the call with DeviceIoControl has something to do with it.
