Hi,

I am writing a Package which includes a lengty process, and I use a 'CProgressCtrl' to give feedback that things are still progressing.
The Process of gathering the information, and establishing a frame of reference to feed the 'CProgressCtrl' is also lenthy.
Windows Installer uses a type of 'Marquee Mode' for this stage, the Progress Bar shows a few marks traveling Left to Right, as a small block, i.e a Marquee. It is a 'Still Alive' message to the User.
How do I Implement a display like that in Practice.

Regards,

Bram Smile | :)

I use a Progress Bar[^] control and do something like:

C++

hWndItem = GetDlgItem(hDlg, IDC_PRBAR);
lStyle = GetWindowLong(hWndItem, GWL_STYLE);
lStyle |= PBS_MARQUEE;
SetWindowLong(hWndItem, GWL_STYLE, lStyle);
SendMessage(hWndItem, PBM_SETMARQUEE, bMarquee, 0);

Thanks Richard.

That was most helpfull. My Compiler is somewhat long in the tooth, and my version of MFC does not support this feature. I hope however, seeing you use the Windows-SDK '::SendMessage()', that we ultimately refer to an SDK 'ProgressControl', somewhere in 'User32.dll', with the MFC Control used as a wrapper. So, my 'XP' version of this DLL should contain the functionality, only my Development Environment does not know about it.

I got the following Manifest Constants elsewhere:-

#define PBS_MARQUEE             0x08
#define PBM_SETMARQUEE          (WM_USER+10)

I also wrote the following code in 'OnInitDialog()'

C++

CDialog::OnInitDialog();

	CWnd*pWnd;
	VERIFY(pWnd=GetDlgItem(IDC_PROGRESS1));
	HWND hWndItem = pWnd->GetSafeHwnd();

	DWORD lStyle = ::GetWindowLong(hWndItem, GWL_STYLE);
	lStyle |= PBS_MARQUEE;
	::SetWindowLong(hWndItem, GWL_STYLE, lStyle);
	::SendMessage(hWndItem, PBM_SETMARQUEE, TRUE, 200);

	return TRUE;  // return TRUE unless you set the focus to a control

Unfortunately, the bar remains dead.
On the other hand, fortunately, it is only a cosmetic nicety, that would be nice to have.
Cast your eye over it, if I did something patently wrong, or if you think is should work under Win XP, let me know. It is still very much a point of interest, but maybe on the longer term.

I think the key question is, Is the Progress Control Implemented by my Compiler Environment(Sic) (in which case I have No Chance in this), or, is it implemented in the OS, in which case there is a problem with my code calling it.

Thanks + Regards,

Hi Bram,
Your code looks fine, but unless your control accepts those settings nothing is likely to happen. According to the documentation here[^] this should work in OS versions from Windows 2000 onwards. However, since you are using the MFC control in a downlevel library you may be restricted. You might like to try implementing the pure Win32 control in order to implement this feature; although you may still require the latest SDK also.

Thanks Richard,

Sorry for the delay, work has been interrupted for a few days due to a beravement in the family.
Well, I have the latest SDK for Windows XP. I see your point about the Down Level MFC Lib. However, I had also thought that actions such as :;Get/SetWindowLong, and ::SendMessage() would bypass MFC in it's entirety. Iow, what I wrote is actually an SDK implementation of the MFC 'SetMarquis()' Function. Afterall, it is the binary code contained in User32.dll etc. that does the actual displaying. MFC is simply a wrapper around the SDK Code, which accesses those system DLL's. Another possibility is one of those 'Stare in the Face' bugs, that take a week or more to find, which turn out to be a small but vital typo.
As said before, it is a Level 5 Bug (Purely Cosmetic). My installer App will Not Stand or Fall with it, at the sametime, it would be interesting to see 'Why' it does not work, if, as you said, The Code looks Fine.

N.B.
(MFC is in my opinion a Very Convenient wrapper. Remember the Man in the late 1980's (Whose Name I've forgotten, who was the Authority on Win 3.1 SDK Programming?) Don't take me wrong, I'm Not dismissing MFC as trivial, but that's what it does. MFC does not Create and Paint Windows, that SDK does not support. I'm not saying it Can't be done, but as I understand it, for Product Development Reasons, MS is unlikely to go that way. Otherways what would be the point in releasing an SDK.)

Hi Bram,
I am stupid, you need to specify to the system that you want the latest level UI controls. I add the following #pragma to my main cpp source module:

C++

#pragma comment(linker, "\"/manifestdependency: \
		type='win32' \
		name='Microsoft.Windows.Common-Controls' \
		version='6.0.0.0' \
		processorArchitecture='*' \
		publicKeyToken='6595b64144ccf1df' \
		language='*'\"")

You can also add it to the Linker Properties somewhere. Give it a try and see what happens.

BTW I think the name you are looking for is Charles Petzold[^], he's still writing useful books.

Hi,

Set the Marquee property to "True".

Hi,

Well, that would be the obvious thing to do, if I could do it. My MFC Implementation has no such property, because it is (atmittedly) a bit long in the tooth.
Apart from that, there is no mention of any such property that I could find, in the MFC Online Documentation.

But, if you have any further Info or Refs on this, Please let me know.

Thanks

Is there an equivilent to the DateTime.Now() in asp.net, I'm writing a time stamp to sql server, and wanted to keep the same format.

dbUA->pzDateOpened = some sort of DateTime.Now();

GetCurrentTime() function should work for you. [^]

Hi,

You can use GetLocalTime()..

SYSTEMTIME st;
GetLocalTyme(&st);

Yeah I saw that, but it looks like I have to build up my Date Time with a structure or something. I didn't understand how to make the request. Perhaps I read it wrong, will look into again today.

You included a sample, will give it a spin today. Thanks.

Richard MacCutchan12-Dec-11 4:59

That's it, done with this one for now.

12-Dec-11 4:59

According to MSDN _ftime[^] is the equivalent.

Thanks for the help Richard.

I was trying to inject the results into a datetime column in SQL via ODBC, but between the 2, it was hard to nail down the error. I didn't know if it was the format of the data, or ODBC not wanting to accept the LPSYSTEMTIME structure, or the size/precision of the data, which for some reason is 23,3.

Ended up with this for now, it works, I can modify it later if I find something better.

SYSTEMTIME systemTime;			
GetSystemTime(&systemTime);
LPSYSTEMTIME lpSystemTime = &systemTime;
			
swprintf_s(szDateOpened,
	L"%d-%d-%d %d:%d:%d",
	systemTime.wMonth,
	systemTime.wDay,
	systemTime.wYear,

	systemTime.wHour,
	systemTime.wMinute,
	systemTime.wSecond
			);
szDateOpened[wcslen(szDateOpened)] = L'\0';

And then sent it to the ODBC Driver in another function. I just need to figure how how to create a MD5 Hash in UT8 for the Encoded Password, and then this part of the program is done.

L"INSERT INTO UserInfo(FirstName, LastName, UserName, PhraseHint, Phrase, PasswordClear, DateOpened, Email, FrontAdmin, SecurityLevel, Enabled, LastLogin) "
L"VALUES(?, ?, ?, ?, ?, ?, CAST(? as datetime), ?, ?, ?, ?, CAST(? AS datetime) )"

and parameterized the values, that one liner took all day long.

retcode = SQLBindParameter(hstmt, 12, SQL_PARAM_INPUT, SQL_C_WCHAR, SQL_VARCHAR, 23, 3, pzLastLogin, wcslen(pzLastLogin), NULL);

I'm afraid my SQL skills are non-existent, but I would suggest you do not store dates and/or times as text values in a database but as datetime (i.e. binary) values. The remarks section in the documentation[^] suggest how to convert it to a large integer. This seems like a lot of work just to save a simple value, but it is Microsoft.

I casted it as datetime, in the ? mark, so sql server does the conversion. CAST(? as datetime)

I'm starting to find out that SQL Server is not that popular in c++. must be a asp.net thing. Oh well. That was easy compared to hashing the password.

Hi,

SYSTEMTIME st;
GetLocalTime(&st);
CString strHour, strMinute, strSecond;
strHour.Format(_T("%d"), st.wHour);
strMinute.Format(_T("%d"), st.wMinute);
strSecond.Format(_T("%d"), st.wSecond);

You can use this to get the current time. I f you need to update the time automatically.Use a timer with one second elapse time, and use this code in OnTimer().

Thanks
