Hi all,
I'm writing program about database.
In my database i have 3 tables:
CDINFO, PERSON, GETGIVE
And i have 3 fields in CDINFO table:
FILMNAME ---> Text
FILMCODE ---> Integer
COUNT ---> Integer
I'm using of three objects of CDaoRecordset for opening each table ...
Now, i want to add new record in CDINFO:
COleVariant var;
char *szFilm = new char[50];
var.vt = VT_INT;
GetDlgItemText(IDC_EDIT1, szFilm, 50);
var.intVal = GetDlgItemInt(IDC_EDIT2);
m_rsCDINFO->AddNew();
m_rsCDINFO->SetFieldValue("FILMCODE", var);
m_rsCDINFO->SetFieldValue("FILMNAME", szFilm);
m_rsCDINFO->SetFieldValue("COUNT", var);
m_rsCDINFO->Update();
SetDlgItemText(IDC_EDIT1, "");
SetDlgItemText(IDC_EDIT2, "");
delete[] szFilm;
This code have not any error or warning, but when i'll running this code, program indicate to me error about: "Out of memory" !!!
Please tell me, what is my wrong ?

What is the purpose of the .chm file? Is is specific to a particular program or something? That info sure would help me help you....

Maybe this will help you understand:
CPerson Reid = "Teenager";
CPerson All_C_Programmers[9999999999];
int i;
int num_Programmers_That_Are_Teenagers = 0;
for (i=0;i<9999999999;i++)
{
if (All_C_Programmers[i]=="Teenager")
{
num_Programmers_That_Are_Teenagers++;
}
}
cout << num_Programmers_That_Are_Teenagers;

This is bad, bad advice. Some of the books mentioned are good books, but no-one, repeat no-one should EVER set out to learn programming Windows without learning C++. In fact the Visual C++ in 21 days is a very simple book, it was my second. The reason I grasped it easily and this person obviously did not is not my stunning intellect ( ask anyone who has met me ), it's because my first book was C++ in 24 hours. Forget windows, menus and everything else until you know enough C++ to write a linked list, populate it from command line input and write it to a file. Once you know some C++, then you'll know half of the stuff in the Visual C++ book, and you'll be able to concentrate on the other half.
C++ is a language created by Bjarne Stroustrup, which amonst other things added classes to the C language. The C++ language does not know about MFC, you can write Windows programs in C++ without using C++, but MFC is a class library that *does* simplify Windows programming.
I'd also recommend buying books instead of downloading them - it takes forever and in the end they are not practical. The books I downloaded early on I either did not use, or I bought.

I'm sorry if you took my comment personally, but your advice *was* bad, and I'm also sorry that you think learning to program properly sounds 'boring'.

I was wondering in terms of efficiency, what is the best way of passing strings and arrays around? What is the penalty one incurs when passing a CString as a opposed to a CString * or when you simply pass by reference?
|
|
|
|

If a function takes a CString, a call to the copy constructor is made since the function gets its own copy of the parameter. Passing a CString* or CString& avoids this.
The CString copy constructor is quick (it just increases the string's reference count) but that's not always the case with all classes. If the function is going to just read the string, make the parameter a const CString&, which is best semantically and speed-wise.

does anyone know how to open up a serial port under NT?
i have had no problems with it under 98, but whenever i attempt to get it to work under NT nothing seems to happen...

There's no fundamental difference between both OSs when it comes to opening serial ports. This should open up "COM1"
HANDLE hCOM1=CreateFile("COM1", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

Ever since I have been using Windows ME, Most MFC apps I create that use Docs do not have the familiar "Untitled" on the titlebar. What I get is this: "____- Appname". Also, many message boxes have only "____" instead of actual text. Common dialogs like the SaveAs dlg will often have "_______" in the titlebar. I have noticed this in other programs that I did not code. MS Paint comes to mind.
Has anyone else experienced this?

You know, I think Ive seen error messages come up as "______- Appname" in Win ME, but havent had the time to find out why.
Its probably something really basic that Im missing.

How can I get a CListCrtl Item into, say, a CString when it is clicked?
Thanks.

When you assign the CListCtrl a variable in the Class Wizard, make sure you assign a variable to the control, and the value...Cumon, you know what im talking about... when you assign the CListCtrl's control ID a variable, it asks for a name: m_?????
then a catagory (in a combo box): Control <----select VALUE here
then for a type (in a combo box): CListCtrl (or whatever)<---select CString here

You can either handle the WM_LBUTTONDOWN message in the List-View and use the folowing to get the item's text;
int nItem = GetNextItem ( -1, LVNI_SELECTED | LVNI_FOCUSED );<br />
CString sItemText = GetItemText ( nItem, 0 );
Or you can handle the List-View's NM_CLICK notification and grab the text as above, using the index given in the NMITEMACTIVATE structure.

Hi,
What I am looking to do is create my own bitmap, out of 2 existing bitmaps. Drawing one half way over another.
Can anyone give me a quick overview of the best way to do this.
Cheers
Richard

By half way do you mean half way along, or alphablended ? If the former, then just draw it on where you want it. If the latter, then you need to access the bits and alphablend them together. GDI+ is the easiest way to do this ( see my articles ) otherwise you need to create DIBSection's, so you can access the bits directly. The issue of CUJ on the wewbsite has code online for a tech tip that shows how to do this. There is also a DIBSection wrapper here on the site.

Hi all,
I need to update the statusbar text of an SDI app. from within multiple views created using a splitter. How do I do this? The statusbar is instantiated in the mainframe (CMainFrame), and I don't appear to be able to access it. It would be nice to create a document level function that could set the statusbar text so that from each of my views I could do something like GetDocument().SetStatusBarText("Hello");
Any ideas??
TIA
Jonathan Thorpe

CStatusBar* CMainFrame::GetStatusBar()
{
return &m_wndStatusBar;
}Now you have access to it. CMainFrame is accessible anywhere; call AfxGetMainWnd() and cast the return to a CMainFrame*
