I'm not sure without digging.
But I'd suggest making two new projects. One with a view inheriting from CScrollView, and one with a view inheriting directly from CScrollView.
Compare, see any differences, enjoy!

In addition, look through your view class (particularly OnInitialUpdate) for a EnableScrollBar command.

You have to remove the WS_HSCROLL and WS_VSCROLL styles from the window.
You may be right

Please tell me how to do that.
I tried following but without luck
BOOL CMyView::PreCreateWindow(CREATESTRUCT& cs)
{
ASSERT(cs.style & WS_CHILD);
cs.dwExStyle &= ~WS_VSCROLL;
cs.dwExStyle &= ~WS_HSCROLL;
if (cs.lpszClass == NULL)
cs.lpszClass = AfxRegisterWndClass(CS_DBLCLKS);
return CView::PreCreateWindow(cs);
}
|
|
|
|
|
Try changing the style instead of the extended style.
You may be right

Thank you very much for the reply. I did chang following in the CMyView class:
cs.style &= ~WS_VSCROLL;
cs.style &= ~WS_HSCROLL;
I did not see cs.style value changing. I think some thing else also needed to be set.
Thank you very much,

Thank you so much for replying my questions. I just post an message in this forum. I found the real reason.
I think "m_wndSplitter.Create" will cause the scorllbar to show.
BOOL CSplitFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
return CMDIChildWnd::OnCreateClient(lpcs, pContext); ---->Scrollbar disappear
}
After I did this. I got another assertion error.

by default, MFC dialog app has a set of code to draw icon: which has a small (16x16) and a large (32x32) icons.
the "small icon" displayed at top-left conner (sys-menu) and min-state (on Windows-start-bar) is not the small-icon of resource, it is resized by 32x32 icon, so it looks very ugly - resizing causes visual problem.
How to display "small icon" with true resource small icon?

Check your icon in the resource editor. There should be a 32x32 and a 16x16 version in the resource. If it only has a 32x32 version then you will need to create the alternate yourself.
|
|
|
|
|
In addition to what Richard said you have to use the LoadImage() API to specifically load and set the smaller icon. The AfxGetApp()->LoadIcon() code supplied by the MFC wizard will only load the 32x32 icon resource.

I want to develop an application with some kind of grid like the one in Excel. I'm using wxWidgets and there's support for the Doc/View-architecture. How many of you out there are using this for c++-applications? Are there better alternatives? It's a MDI-application with very few dialogs. If that matters.
|
|
|
|
|
Doc/View is not a good design - mu opnion.
But if you use MFC, you should use Doc/View, or may have trouble.
|
|
|
|
|
How come you think it's a bad design?
|
|
|
|
|
The answer really depends on whether it is reasonably easy for you to develop your application using it, and whether it will satisfy your needs, in terms of finished product. And if you really want MDI then Doc/View is probably your best option. I have used it in the past and found it produces very usable programs.

Doc/View is probably not quite as good as MVC (it's ambiguous where UI commands should be handled) as used and promoted in Qt[^], but all of these architectural styles rely on your detailed design and implementation not violating the qualities implicit in thm.
So, in the case of DocView, make sure the Doc class is entirely unaware of any of the views. It should provide methods sufficient for the view to display the document and modify the document, should you choose to handle the UI commands outside the document class.

thank your for your informative reply. But MVC is not used in C++ is it? I thought it was for web applications only. Do you know of any documents that describe the Doc/View architecture in a way that's not MFC/wxWidgets-specific?

It's not language specific - no architectural design patterns are, really, apart from those low-level design patterns that are more about getting around deficiencies in some languages.
DocView (IMO) is basically a Microsoft derivation (and simplification, which loses some of the purity) of MVC. Have a look at the Wikipedia page on MVC[^] - although it talks a lot about web stuff, the history section shows that it is definitely NOT web specific. I don't really know of any Document/View documentation that isn't MFC/wxWidgets related.

I don't know of any specific documents, but I would expect that MSDN contains a lot of the information you need to utilize the Doc/View architecture, including sample code.

Hi all,
I have migrated my application(vs-2003 developed) into vs-2008 to be worked on vista machine.I got the .exe and working successfully when i enter a valid username and valid password but fails when i enter a wrong password/username......I am using SYBASE for my aplication,so it comunicates with some SYBASE dlls to get the access.
the code looks like below
(I am providing login details from other dialog)
int DBInterface::LoginSequence (BOOL bFirstLogin)
{
CString user_name;
char dbver[16];
CString srvrname, dbname;
char uname[33];
char upwd[33];
UINT msg;
if (bFirstLogin)
{
dbinit ();
dbsetlogintime (8);
dbmsghandle ((MHANDLEFUNC) msghandle);
dberrhandle ((EHANDLEFUNC) errhandle);
}
int rv = 0;
while (Ops.m_bAutologin && bFirstLogin)
{
if (CSD_DdeReqUserName (uname) == 0)
break;
if (CSD_DdeReqUserPassword (upwd) == 0)
break;
srvrname = App.GetProfileString (INI_SEC, _T("DBServer"), "");
if (srvrname.IsEmpty ())
break;
dbname = App.GetProfileString (INI_SEC, _T("DBDatabase"), "");
if (dbname.IsEmpty ())
break;
strcpy (_loginfo.dbid, uname);
strcpy (_loginfo.dbpwd, upwd);
strcpy (_loginfo.dbsrv, srvrname);
strcpy (_loginfo.dbdb, dbname);
_dbproc = dbConnect (&_loginfo, "Phoenix");
if (_dbproc == NULL)
break;
rv = 1;
TRACE0("Phoenix: successfully logged in using LOGPARMS from anotherapp...\n");
break;
}
CLoginDlg dlg;
while (rv == 0)
{
if (dlg.DoModal() != IDOK)
{
PostQuitMessage(0);
return 0;
}
else {
lstrcpyn(_loginfo.dbpwd, dlg.m_csPassword, 31);
lstrcpyn(_loginfo.dbid, dlg.m_csUser, 31);
lstrcpyn(_loginfo.dbsrv, dlg.m_csServer, 31);
lstrcpyn(_loginfo.dbdb, dlg.m_csDatabase, 31);
}
_dbproc = dbConnect (&_loginfo, _T("Phoenix") );
if (_dbproc != NULL)
break;
msg = (::GetKeyState (VK_CAPITAL) & 0x0001) ?DS_ERR_LOGINFAILEDCAPS : IDS_ERR_LOGINFAILED;
if (AfxMessageBox (msg, MB_OKCANCEL | MB_ICONHAND) == IDCANCEL)
{
PostQuitMessage(0);
return 0;
}
}
In the abobe code from dbconnect()(bold code) it is calling some SYBASE dll and it is not getting the return value when i enter wrong password/username.......
Is there any problem with the dll or anyting else?????
Since i have migrated the code i am thinking that the dll is not compatiable,but this is just an assumption....!
So can anybody help me to solve this issue......
Thaks in advance.

How can I change the text color of an edit control? I want it to change to red when its contents aren't correct.

How do I trigger this message to be sent? Should the code be something like
bool m_bRedColorFlag [= false];
...
void OnCtlColor()
{
if (m_bRedColorFlag){
}
else {
}
}
...
m_bRedColorFlag = true;
GetDlgItem(IDC_EDIT)->InvalidateRect(NULL);

Hi Friends,
I made a desktop and audio(mike) capture GRF in graphedit.
On some systems audio recording stops after 30 sec but video recording has no issue.
I did all things in source code(c++ application) tracked IMediaEvent, but as audio recording stopeed in between no error event is fired.
Note: problem occur only on some laptop pc till now it has not occured in any desktop PC
Laptop "qasf.dll" version is 10.0.03802
I tried with differnt versions of same dll but all in vain on the laptop.
System configuartion is below:
RAM - 1790MB
CPU - Intel(R) Core (TM)2 duo CPU 1.83Ghz(2 CPU)
GRF file is stored at below link

Thanks,
