Hi,

1. I have put a TabControl inside a formview in the MFC-SDI application. If I resize the window I want the tab control to always fit in the window (that means if I make the window bigger the control inside will become bigger and if I make the window smaller I want the control to get smaller). Please advise how I can do that?
2. How can I make a SDI application non-resizable?

Thanks,

Add a WM_SIZE handler in your view class. In it, do the following:

CRect rectView;
GetClientRect (&rectView);
m_tabCtrl.MoveWindow (&rectView);

This will cause the tab control to fill the view's client area.

I used following code Onsize
but I'm getting asserting error at line 279 of winocc.cpp

CFormView::OnSize(nType, cx, cy);

CRect rectView;
GetClientRect (&rectView);
m_TabCtrl.MoveWindow (&rectView);

Perhaps you haven't linked m_tabCtrl to the tab control in the dialog template? Put this line before the call to MoveWindow():

ASSERT (m_tabCtrl.GetSafeHwnd() != NULL);

to ensure that m_tabCtrl has been properly created before you try to resize it.

It worked. Thanks.... I have another similar question Smile | :)

I have two tree controls attached to the tabs in the tab control. To fit the tree control in the tab control what should I do? 'cause I can't write the wm_size handler for the tabcontrol as I'm adding the tree controls in the formview, not in the tabcontrol class.

I think you might be confusing a CTabCtrl with a CPropertySheet. A CTabCtrl doesn't "contain" child dialogs or controls - all it does is allow the user to select a tab. A tab control's parent receives notifications when the current tab selection changes.

That being said, what you probably want to do (to mimic the behavior of a CPropertySheet) is to create a bunch of child controls/dialogs (whose common parent is your view), one of which is displayed in response to the change in the currently selected tab. You'll also need to check the "Transparent" attribute of the tab control so that it doesn't hide the child controls/dialogs. The appropriate control/dialog is displayed in response to a change in the currently selected tab in the following manner:

// First hide all controls
CWnd* pDisplayedWnd = NULL;
m_treeCtrl_1.ShowWindow (SW_HIDE);
m_treeCtrl_2.ShowWindow (SW_HIDE);

// Next, determine which one should be shown
int nCurTab = m_tabCtrl.GetCurSel();
switch (nCurTab) {
  case 0:
    pDisplayedWnd = &m_treeCtrl_1;
    break;
  case 1:
    pDisplayedWnd = &m_treeCtrl_2;
    break;
  default:
    // Did you forget to support a tab?
    ASSERT (FALSE);
    break;
}
ASSERT (pDisplayedWnd != NULL);

// Display the control
pDisplayedWnd->BringWindowToTop();
pDisplayedWnd->ShowWindow (SW_SHOW);
pDisplayedWnd->Invalidate();
pDisplayedWnd->UpdateWindow();
pDisplayedWnd->BringWindowToTop();
pDisplayedWnd->SetFocus();

If this is too much work, you might want to consider using a CPropertySheet. See the examples at CP if you need help.

Don't forget to call SetScaleToFitSize(cx, cy) at he end of your OnSize() procedure otherwise you will get scroll bars shown if the client rectangle size is smaller than the size of the dialog template used to create the form view from.

I'm using a formview here, setscaletofitsize() is for the scrollview. can you please tell me how I can use it for the scroller in the formview?

worked

SIZE sizeTotal;<br />
sizeTotal.cx= cx;<br />
sizeTotal.cy= cy;<br />
CScrollView::SetScaleToFitSize( sizeTotal);

Dear all,
In Windows 2000/XP platform, we can easily get this information from function DeviceIoControl with code IOCTL_DISK_GET_DRIVE_LAYOUT. However, in Windows 98/Me, we failed. We all know that most of the fields in this struct are located at MBR and the first sector of each partition.

typedef struct _DRIVE_LAYOUT_INFORMATION {
DWORD PartitionCount;
DWORD Signature; // ********
PARTITION_INFORMATION PartitionEntry[1];
} DRIVE_LAYOUT_INFORMATION;

typedef struct _PARTITION_INFORMATION {
LARGE_INTEGER StartingOffset;
LARGE_INTEGER PartitionLength;
DWORD HiddenSectors;
DWORD PartitionNumber;// ********
BYTE PartitionType;// ********
BOOLEAN BootIndicator;// ********
BOOLEAN RecognizedPartition;// ********
BOOLEAN RewritePartition;// ********
} PARTITION_INFORMATION, *PPARTITION_INFORMATION;

Unmarked fields are got easily from partition entries in MBR and the first sector of each partition. The marked ones are unknown. Therefore, my question is how to get those marked fields? I mean the other ways to get that information in Windows 98/Me platform. Thank you very much.
Best regards.
Tuan Dang.

Logging in as another user from a service

I have a program that runs as a service. It needs to run a program under another user's account. The service will have access to a username/password. The service, of course, is running under the System account.

I have investigated CreateProcessAsUser, but for the life of me I cannot get it to work as expected! I can use LogonUser to get a token, and then pass it to CreateProcessAsUser, which dutifully runs the program and returns no errors, but from all observations, the program does not seem to run under the right account.

Any ideas? I'd post code, but it is pretty bulky. I got it from an article here on CP about a Telnet server. OR just to test, is there a relatively easy way I could, say, print the name of the user I'm running the code as, or some other sure-fire test?

This service may be running with or without the given user logged on, so I'm not sure if that makes a difference.

Thanks.

Maybe this is at a tangent to what you're asking ...
What privileges does your service have ?? - My security handbooks are at home, but I would have thought to be able to do this you would need higher privileges than a standard account (or the local system account) ..

It would seem odd to need higher priveleges than the standard System account... doesn't that have pretty much everything? WTF | :WTF:

And then who'd be able to set the system account privileges? Granted, I wouldn't be surprised if this were the case... although that would pretty much sink any hopes I'd have of implementhing this idea.

AFAIK, CreateProcessAsUser and LogonUser need the following four privileges: SeIncreaseQuotaPrivilege, SeAssignPrimaryTokenPrivilege, SeChangeNotifyPrivilege, and SeTcbPrivilege

Im just looking for some articles that may help you ...
