Thanks for the link, very interesting but I think I'll stick with pointers for now.

First of all, I am a new programmer and dont know much.. This is what I'm trying to do.
Write a program for Jail Administration (inmate info, book-in info, book-out info etc) but this program must also be able to extract data that is already entered into the fingerprinting system. This fingerprinting system takes the pictures and has most of the inmates information (but not all). So I need to be able to add an inmate to the fingerprint system and my new program on a seperate computer automatically add this information as well and then I can go in and add the additional information.
Or even the other way around.. when I add info on my program I make in sends it to the fingerprinting system via network..
I'm just trying to get some direction on how to get this done. Any help would be appreciated. Thanks

Use a 'database' , 'query' it or 'update' the 'tables'. 
I hope you heard all those words in your last class.

Do you have control over this "fingerprint system" such that it can send your program the data?

I work in windows xp with visual studio c++ 6, by default byte alignment is 8, and qt 3.2.2. i have a program with the default byte alignment that work well.
I need to change byte alignement of my qt program to 4. Changing alignemnt of the program result in a popup error window, in the call of the show qt function of the window. If i don't call the show function the program doesn't produce no error and run ok .
I've tried both: changing byte alignemnt of all the projects (in the settings dialog), and just changing the alignment of a struct by writting pragma pack(4) before definition of the class.

OK - I'll bite - couple of questions first:
- Why change the alignment?
- Can you show us the call-stack resulting when the exception is raised?

1.because i have another application that work in byte alignment 4. this other application receive msg from another computer that work in byte alignement
2.No i can't, i'll just copy a few line of it.
but i didn't see something interesting in the call stack;
qt-mt322! an address
MainWindow::qt_invoke(int,QUObject*)
qt-mt322! an address
qt-mt322! an address
....
Gui!WinMain...
When installing qt, it compile it, must i compile qt from scrath with flag zp4 ?

Is the message received from the other application a Qt object? If not, I fail to see why altering the packing of a single non-Qt structure should cause a problem.

Looking at the call stack, I'd say your issue is Qt related, which could well mean that you're giving the Qt DLL an object with an alignment it's not expecting.

When execute the MDI application (Created purely by framework), the first child frame window is always created automatically!!! Anyone know how to disable this ?
Thanks and Regards!

In your MyApp::InitInstance, there will a line line:
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
and
if (!ProcessShellCommand(cmdInfo))
return FALSE;
Put the following in between:
if (cmdInfo.m_nShellCommand == CCommandLineInfo::FileNew)
cmdInfo.m_nShellCommand = CCommandLineInfo::FileNothing;
Hope that helps!

It worked, thank you very much!
I've considered these lines of code while searching for the answer, but didn't care much because i don't know anything about command line parsing.

|

In your class derived from CWinApp, add the indicated line between the definition of cmdInfo and the call to ParseCommandLine in the InitInstance method:
CCommandLineInfo cmdInfo;
cmdInfo.m_nShellCommand = cmdInfo.FileNothing;
ParseCommandLine(cmdInfo);

I'm stumped on this one
I have a class, with a private unsigned char array.
I have a class method which is const. It is trying to write to the private unsigned char array, but I get the assignment of read only location.
I can't touch the headers/remove the const because it is an inherited virtual function. How do I access the unsigned char array?

I presume it's private in your derived class (it's difficult to tell, as you haven't posted the code...). In that case, declare it as mutable. That way you can modify it even in a const method.
However, unless (say) the array is a cache, is the design correct?

1. Hãy tổ chức lớp và viết chương trình ứng dụng cho phép nạp và hiển thị các loại tập tin ảnh có phần mở rộng thuộc một trong các loại .jpg, .bmp, .dib, .gif. Chương trình có chức năng thay đổi ảnh như lật ngang, dọc (mirror), quay 900, đổi sang mức xám, lấy âm bản, lấy sai biệt của hai ảnh và chức năng lưu trữ sang dạng khác (nhưng vẫn là một trong các dạng kể trên).
Yêu cầu: Tổ chức theo tư tưởng hướng đối tượng. Có thể lập trình trong môi trường Windows. Không xử dụng hàm static như ví dụ trong phần lý thuyết, không dùng switch, case trong chương trình.
2. Một “đầu vào thư mục” là một thư mục hoặc một tập tin, một thư mục gồm nhiều “đầu vào thư mục”. Ổ dĩa là một trường hợp đặc biệt của thư mục. Hãy tổ chức lớp để có thể biểu diễn khái niệm máy tính, ổ dĩa, thư mục, tập tin với các mối quan hệ như trên. Viết chương trình ứng dụng cho phép xem nội dung các loại đối tượng trên theo dạng tương tự như chức năng Tree của phần mềm NC.
3. Cho các loại đối: hình tròn, hình ellipse, đa giác, hình bán nguyệt, hình cánh quạt, hình thoi, hình bình hành, hình thang, hình chữ nhật, hình vuông, hình tam giác, tam giác vuông, tam giác vuông cân. Viết chương trình ứng dụng cho phép tạo (hoặc nhập) hai hình thuộc một trong các hình kể trên. In thông báo cho biết hai hình có giao nhau không, nếu có to màu phần giao và tô đậm đương biên của phần giao. Người sử dụng có thể bấm các phím mũi tên để di chuyển một trong hai hình, phím +, -, để phóng to thu nhỏ một trong hai hình. Chương trình có thể hoạt động với các loại thiết bị xuất khác nhau: Chế độ đồ hoạ, chế độ văn bản (mỗi dấu ‘*’ là một pixel luận lý). Chương trình có khả năng zoom với pixel luận lý, khi chuyển từ chế độ đồ hoạ sang văn bản hoặc ngược lại, người sử dụng không thấy các đối tượng bị to khổng lồ hoặc bé tí hon.
4. Một đường Polyline gồm nhiều đường (line), mỗi đường có thể là một đoạn thẳng (strait line), cung (arc), bezier hoặc một polyline. Tổ chức các lớp cần thiết, thiết lập mối quan hệ giữa các lớp và viết chương trình cho phép tạo các polyline, tạo bản sao của polyline, phóng to, thu nhỏ, quay polyline, phân rã polyline (tách các polyline con bên trong một polyline thành các đường đơn (line, arc, bezier), hàm xác định hai polyline có cắt nhau hay không?

Hi,
I'm sure GDI+ can do that.
Sorry I can't provide any details, I have trouble catching the nuances of the Vietnamese language.
