If you don't mind using 100-ns intervals since 12:00 AM, January 1st, 1601, then GetSystemTimeAsFileTime is the way to go.

I'm trying to create a custom control which contains a few input fields.
I've read Chris Maunders tutorial courses about 'the art of subclassing' and 'create your own custom control' which are btw great, but still I can't seem to find out where to begin.
Basically I want to create a small control with 2 input fields, some text and a button or 2. Let's say a login control containing username, password and a connect button.
There are a lot of good articles about subclassing for instance a CEdit field, but I can't find one that handles my question.
Does anybody know if it is possible to create this control starting from a dialog? Or should I just sublass a CWnd and add the Edit/static fiels and button myself. How to do this?
I really can't figure out how to start, so it should be great if anyone can point me out how to start.
Thanks in advance
Wim

You'll need a child dialog. Derive your class from CDialog, create a dialog template with 'child' style set, add controls on the dialog surface and add event handlers. At runtime, you'll need easy method for placing child dialog on the parent. I'm usually using 'dummy' static control which provides the initial position and size and it's replaced with child dialog.

Hi.
I am trying to create a wizard-style property sheet.
I want to add header & watermark images to it.
The header gets displayed, but the watermark does not appear.
Here is the piece of code.
HBITMAP hbm1, hbm2;
hbm1 = LoadBitmap(::AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BMP1));
hbm2 = LoadBitmap(::AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BMP2));
m_ps.Construct("Options", NULL, 0, hbm1, NULL, hbm2);
m_ps.m_psh.dwFlags |= (PSH_WIZARD97 | PSH_WATERMARK
| PSH_USEHBMWATERMARK | PSH_STRETCHWATERMARK
| PSH_WIZARDCONTEXTHELP | PSH_HASHELP
| PSH_HEADER | PSH_USEHBMHEADER);
I tried various combinations of the flags, but the watermark image is not getting displayed. 
Does this require some change to the property pages?
ALso, I am unable to add header title/subtitle.
I use VC++ 6.0
Can somebody guide me?
Thanks.

This is a complete mystery to me - ive opened an access database, and its only recognised 1 row:
{
CSoundFile* pSoundFile = new CSoundFile();
pSoundFile->Open();
CString tmp;
tmp.Format("%d - %d ", pSoundFile->GetODBCFieldCount(), pSoundFile->GetRecordCount());
tmp += pSoundFile->GetTableName();
AfxMessageBox(tmp);
}
The messagebox outputs "2 - 1 [soundfilelookup]". However there are loadsa records in the database. Does anyone know what the problem is??

If my memory serves me correct...
The recordcount may not be accurate until EOF is seen (i.e. you have iterated through all records).

Cheers mate, i'll give it a try
|

|

Exact ! but i think you have just to move to the last record.

I've a ReBar in my SDI-Application and an Extended Combo Box in it. With the help of Class Wizard I select an existing class (CMainFrame) to be associated with the IDR_MAINFRAME resource of the rebar. In CMainFrame I create a OnSelChangeComboboxex1() function.
It looks like this:
CComboBoxEx *pCombo = (CComboBoxEx *)GetDlgItem(IDC_COMBOBOXEX1);<br />
int nSel = pCombo->GetCurSel();
etc.
But the program fails because of some unhandled exception. I really don't know what the problem can be. Someone, please, help!

If this is really urgent, why can't you provide more information on 'some unhandled exception'?
Is your combo a child of mainframe, or rather it's located on rebar?

Even though CMainFrame may be getting messages sent by it, the combobox is not actually a direct child. So GetDlgItem() is returning NULL, hence your crash. You'll need to obtain a handle to the ReBar window (this should already be a member of CMainFrame) and use that to obtain the combobox handle.

Thanks, I've got your idea. But how exactly should I obtain a handle to the ReBar window? (sorry, I'm just a beginner)
|

It should be a member of your CMainFrame class. Probably it's called m_wndReBar. Note that the ReBar control itself only contains other windows, so it could contain the combo box itself, or the combo box could be on a dialog bar contained by the ReBar; i'm not sure how you set this up, so i can't say for sure. If you *are* using a dialog bar, there'll be another member of CMainFrame for that. Poke around a bit, it should all be clear.

Oh yeah, thanks, that helped, it turned out to be m_wndDlgBar

Hello:
I need help with Combo boxes. I have a combo box in a dialog and I want to fill the combo box with some filenames of a specified directory. Then, after filling the combo box, I'm disabling it (it can be enable by a check box in the same dialog). The program complies and runs, and when I load the dialog with the combo box, when I click the check box to enable the combo box, there is nothing in it. This is the code snipet that I have in the ::OnInitDialog() event:
::SetCurrentDirectory(_T("C:\\sounds"));
m_cbo.ResetContent();
m_cbo.Dir(DDL_DIRECTORY,_T("*.wav"));
m_cbo.EnableWindow(FALSE);
Is there something that I'm missing inthe combo box? What can I do to solve this? Any answer is more than welcome.
Best regards,
Luis E. Cuadrado

Change DDL_DIRECTORY to DDL_READWRITE.

I've just looked at the sample code in the MSDN documentation, and it looks like you might need the DDL_READWRITE flag as well as the DDL_DIRECTORY flag:
m_cbo.Dir(DDL_READWRITE | DDL_DIRECTORY, _T("*.wav"));I could be wrong though, I've never used CComboBox::Dir.
If it still doesn't work, it might be worth checking the return value of the Dir function - it should be a positive value if everything's worked okay. If it returns zero, that means no files were added. A negative value indicates an error.

Hello again:
I edit the code. I tried using DDL_READWRITE | DDL_DIRECTORY and using just DDL_DIRECTORY and I wasn't able to see any files in the combo box. I click the little arrow of the combo box and nothing comes down. I wonder if is something related with the combo box. Any property that I have to change or something. What do yo guys think?
Thanks for the replies,
Luis E.

Your combo may have very small dropdown area. In the resource editor, click on the combo box arrow, then resize the dropdown rectangle.

My understanding of CWnd::FromHandlePermanent is this :-
If there is an existing CWnd within the current application's heap/stack that currently holds the window with the passed window handle, then CWnd::FromHandlePermanent will return that CWnd*.
But unfortunately that's not happening. It does return a permanent CWnd but it's not matching the original CWnd 
So is my understanding flawed or is this some kinda funny side effect of something else in my code?

FromHandlePermanent doesn't walk the stack or heap. It just checks the permanent map; permanent map gets new entries when you create objects derived from CWnd. It doesn't get updated when you call methods returning temporary CWnd's (like CWnd::FindWindow).

Can you check the 'original CWnd' in QuickWatch window? Is it CTempWnd object?

Hi Nish,
Note that if you are using different threads then you won't see the CWnd* which is in one threads map in the other. Could this be the problem?
