The alleged IsUserAnAdmin() API doesn't exist in shell32.dll like MS claims. Confused | :confused:

Use Depends and see for yourself. Weird.

Yeah, you're right. Maybe it's one of functions exported by ordinal??

Sam Blackburn's Win32 Foundation Classes (WFC) [^] provide a function called wfc_am_i_administrator that serves this purpose.

No. You have to do it manually. Search for SID in MSDN.

DC, bitmaps, and view questions

I've tried using a CStatic control in my CView derived class to animate a bitmap. I use 4 separate bitmaps but after a couple of minutes (variable) it fails and I get an error related to CBitmap. This also messes up all of Windows graphically. So, after playing around with it, I decided to give up on CBitmap and CStatic. FYI, here is what I had:

MyViewClass::OnTimer(UINT nIDEvent)
{
	if(nIDEvent == m_AnimTimerId)		
	{
		if(BmpId == IDB_ASTLEFT + 4)
			BmpId = IDB_ASTLEFT;

		CStatic *pTargetCtrl = (CStatic *) GetDlgItem(IDC_ERR_STATIC);
		ASSERT(pTargetCtrl != NULL);

		m_CurrentBmp.Detach();
		m_CurrentBmp.LoadBitmap(BmpId);
		pTargetCtrl->SetBitmap(m_CurrentBmp);

                BmpId++;
        }
}

So, I decided to use memory DCs and blt it onto the screen. However, I am not sure I am obtaining the DC correctly since I get an error in the bitblt routine now used in the timer routine.

void CStatsView::InitialDraw()
{
	pTheDC = GetDC();

	// create memory DCs and select animation bitmaps into them for blitting in the timer event
	// for updating the animation. This is done here so that bitmaps are loaded once and only once
	// and they are selected into the memory DCs once also.
	CBitmap			bmp1, bmp2, bmp3, bmp4;		// first, create 4 bitmap objects

	bmp1.LoadBitmap(IDB_ASTLEFT);
	bmp2.LoadBitmap(IDB_ASTLEFT+1);
	bmp3.LoadBitmap(IDB_ASTLEFT+2);
	bmp4.LoadBitmap(IDB_ASTLEFT+4);

	// create compatible memory dcs - compatible with the display
	dcMem1.CreateCompatibleDC(pTheDC);
	dcMem2.CreateCompatibleDC(pTheDC);
	dcMem3.CreateCompatibleDC(pTheDC);
	dcMem4.CreateCompatibleDC(pTheDC);

	// select bitmaps into their respective memory dc
	dcMem1.SelectObject(&bmp1);
	dcMem2.SelectObject(&bmp2);
	dcMem3.SelectObject(&bmp3);
	dcMem4.SelectObject(&bmp4);

}

The OnTimer code now looks like this:

if(BmpId == IDB_ASTLEFT + 4)
    BmpId = IDB_ASTLEFT;
switch(BmpId)
{
    case IDB_ASTLEFT :
        pTheDC->BitBlt(0, 0, 7, 7, &dcMem1, 0, 0, SRCCOPY);
    break;
    case IDB_ASTLEFT + 1 :
            pTheDC->BitBlt(0, 0, 7, 7, &dcMem2, 0, 0, SRCCOPY);
    break;
    case IDB_ASTLEFT + 2 :
        pTheDC->BitBlt(0, 0, 7, 7, &dcMem3, 0, 0, SRCCOPY);
    break;
    case IDB_ASTLEFT + 3 :
        pTheDC->BitBlt(0, 0, 7, 7, &dcMem4, 0, 0, SRCCOPY);
    break;
}

BmpId++;

If that is the case, where in my view should I obtain a pointer to the DC?

Use CClientDC, which encapsulates calls to GetDC/ReleaseDC. You should also use CClientDC in InitialDraw.

progress bar never shows on status bar

RalfPeter3-Sep-02 9:26

I cannot get my progress bar to show on the status bar. The only way I found around it to show is to use MyPBar.SetWindowPos(...). Doing it this way, though, mispositions the progress bar on different computers. How do I lock it to my status bar? Here's what I have:

In MainFrm.cpp:
CRect rect;
m_wndStatusBar.GetItemRect(2, &rect);
m_ProgBar.Create(WS_VISIBLE | WS_CHILD | PBS_SMOOTH,
rect, this, ID_INDICATOR_PBAR);
m_ProgBar.SetRange(0,100);//Set the range to between 0 and 100
m_ProgBar.SetStep(1);//Set the step amount
//the line below is brute force, can't find out how to display ProgBar
m_ProgBar.SetWindowPos(NULL,782,714,105,16,NULL);

In CView.cpp (or elsewhere):
.
.
.
CMainFrame* pFrame = (CMainFrame*)AfxGetApp()->m_pMainWnd;//pointer to mainframe object
.
.
.
pFrame->m_ProgBar.StepIt();//never shows on status bar

Any suggestions? Thx

You should make progress control a child of status bar, not main frame. Check Q142202 for details.

DAO: linking dbf table with different extension

AndyR3-Sep-02 6:16

AndyR

3-Sep-02 6:16

The following code works with DAO 3.5, but it doesn't when I add the following line into InitInstance():

<br />
AfxGetModuleState()->m_dwVersion = 0x0601;<br />
....<br />
<br />
CDaoDatabase db;<br />
db.Create("c:\\test.mdb");<br />
<br />
CDaoTableDef td(&db);<br />
<br />
td.Create("test link");<br />
td.SetConnect("dBase IV;Database=C:\\");<br />
<br />
// test.ddf is a dbf created with FoxPro 2.5x & renamed:<br />
td.SetSourceTableName("test.ddf");<br />
<br />
td.Append();<br />

The error message is "The Microsoft Jet database engine could not find the object 'test'. Make sure the object exists and that you spell its name and the path name correctly."

I've tried using "test#ddf" as a vaguely remember reading that this is the key to getting non standard extensions accepted, but this makes no difference in Jet 3.5 or 3.6 (i.e. 3.5 still works Smile | :)

, 3.6 doesn't work Frown | :(

Any ideas?

MFC 6.0 has the ability to use Microsoft Access 2000 databases. To engage this support in your application you use.

AfxGetModuleState()->m_dwVersion = 0x0601;

So to use under DAO 3.5 just remove the line

Hmm...

Classwizard Problem w/ External Resource DLL

3-Sep-02 5:37

Hi all...

I've got a problem that arose after moving the resources in our application to an external resource dll for localization. All that works fine, but now the ClassWizard is basically unusable for adding new members based on controls in the dialogs. I know it's got something to do with the fact that all the control and dialog definitions are not part of my main app's project anymore... but..

does anyone know how to fix this?

Thanks in advance,
Andrew Welch
