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,

What controls the hovering expansion of MFC menus?
Or what controls which choices are shown before hovering on the little arrow to expand the rest of the menu?
A. The feature is called Personalized Menu Behavior.
The wizard code for it is in CMainFrame::OnCreate()

Thanks. Really though I know this is a stupid question or maybe its just me but I haven't been able to find it in the help because I can't think what the feature is called to be able to search for it in the MFC docs or code. When I google "Menu Expansion" I get 7500 hits that all seem to have to do with web development, java, of C#.

It's all right there in the help. There is a link to a sub page about menu programming considerations which has a section on menu messages, creating menus and modifying menus. It really is too big a topic to fully explain in a forum post.

Hello,
I'm new to C++. I grasp it, having read through a number of articles and chapters of books
and done a bunch of console examples.
I have my Visual C++ and the latest Windows SDK for Windows 7.
So, I want to skip ahead and start creating simple GUI's using png, jpeg or gif files as well as vector drawing.
So, If anyone can offer some guidance, I will appreciate it.
What is the most CPU efficient, smallest file size method to create a GUI incorporating png files? Cross platform or windows. A WYSIWYG editor would be nice, but most important to me is to have solid, professional code, so I want to focus my research on methods that develop good GUI's, even if it requires more time.
I have used software with GUI's that load in a clumsy fashion and are buggy. That is what I want to avoid. I want my apps to run smoothely.
So any programmers willing to point me in the right direction?
Thanks,
-Matt

Bitmap Basics - A GDI tutorial[^], is a good place to start; fairly basic but makes it easy to grasp the concepts. You should always take a look at Microsoft's GDI+[^] for the latest functionality. And when you feel comfortable with all that, then this article[^] teaches some really cool stuff.
Good luck!

Thanks,
So I'm looking at Win 32 development, and I need to work with the libraries there.
Windows GDI and GDI+, and maybe others like Direct 2D, I guess. Thats plenty to learn about for awhile.

Hi. Well... I'am trying to develop some simple game. This game has map of CButton objects and a marine that is a CButton object too. I have to make someway that marine go over other button. But as soon as i draw them marine is left behind the map. I tryed to make another transparent window and collocate marine there. It worked, but... in OnInitDialog i write:
MarineDlg.Create(IDD_MARINEDIALOG,this);
theApp.CreateLvl(this, STARTPIXELX, STARTPIXELY, FIELDSIZE);
and it's all cool, BUT if i write
theApp.CreateLvl(this, STARTPIXELX, STARTPIXELY, FIELDSIZE);
MarineDlg.Create(IDD_MARINEDIALOG,this);
marine is left behind and i need to create level first because my marine use it's properties.
Any hint? Some way to solution?
Pls. I already lost 1 day in it with no result.
