Turns out VC++ 2005 is correct according to the C++ specification. http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=135955&SiteID=1[^] In VC++ 2005, you can directly change the namespace name, including nesting namespaces, and the Windows Forms Designer will still manage to parse the file. Me jump to conclusions, but MSFT is right on this one.

string strd1 = "9";
int m=atoi(strd);
Got the error: error C2664: 'atoi' : cannot convert parameter 1 from 'class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >' to 'const char *'
how to change the second line to make it work?

This is the correct way:
string strd1 = "9";
int m = atoi(strd1.c_str());
|
|
|
|

I have the same problem long time ago. It is a mix mode of string vs char. Here the solution:
define string strd1 = "9"; as char strd1 [1]="9"; or CString strd1 ="9";

Multi-dimensional BST is a BST with multi-dimensional keys.
In a k-dimensional BST, each node has a k-dimensional data and the tree indexes dimension i of the data at level i. For a node at level i, its discriminator, disc = i % k, that is, kdisc is used to discriminate its descendants.
Example For a 3-d BST, each node is a vector of 3 keys, < k0, k1, k2 >.
For a node at level i, its discriminator, disc = i % 3, kdisc is used to discriminate its descendants.
Similar to BST, we can perform the basic operations such as Insert, Search and Delete. For the first two operations, only a little extra checking has to done when traversing the tree. As for deletion, it is a bit complicated to find the successor / predecessor of the node to be deleted.
Do any one know how to implement?

I am using C++ in VC++ 2003
there are some examples like this http://www.codeproject.com/cpp/miniexcel.asp
but I don't quite understand.
I hope someone could help me or guide me to some related documents, bow!

That article is not really "about" Excel Automation. You need to research the Microsoft Office Object Model specifically the Excel Object Model. The MSDN site has examples and of course the documentation to these COM interfaces.
If you posted this in the correct forum it means you are using the .NET runtime for your project. In that case you can use the Microsoft supplied .NET libraries. http://support.microsoft.com/kb/302084[^]

I am using the MFC dialog application.
There are 3 edit box, add1, add2 and sum
and a button "add",
when exectuing, I input add1, add2, and use the "add" function dlg.m_sum=dlg.m_add1+dlg.m_add2
how to make the sum appears in the "sum" edit box? Do I have to add a view class or how to modify the OnPaint?
I now only have add.cpp and addDlg.cpp

Then you're not using C++/CLI, are you ?
bloodwinner wrote: dlg.m_sum=dlg.m_add1+dlg.m_add2
I assume you have associated ints with the text boxes, not edit controls ?
Then you need to call UpdateData before you do the calculation, to bring down the variables, and UpdateData(FALSE) after the calculation, to populate the controls again. Or, maybe the other way around.
Please ask in the right forum next time

Hi there,
Could any one tell me how I could disable user from viewing resources (i.e. dialogs, icons, menu, etc.) in an application exe file? I have an application that is written in unmanaged C++ in VS 2005 compiled with /clr option. Any help would be greatly appreciated.

Thanks Mike for the info. But I have a problem when I run it, it says.
upx: Myprogram.exe: CantPackException: .NET files (win32/net) are not yet supported
You know other software that support .net exe file?
Thanks

Hi!
What I'm trying to do is a tool that would help my at work with big number of open windows. It should:
1.Close window when I click middle button over titlebar of window (done)
2.Close window when I click over window's button in taskbar area.
The second one is for me too hard. I manage to catch mouse click using system hooks, but I don't know how to get HWND to specific button. I have whole taskbar handle insted. Sending WM_CLOSE couse closeing system :/.
How to get HWND of taskbar button that was clicked by mouse middle button?
Or how to acquire second goal other way?
Thank You for any help

Hi, I'm wondering how I can remove the 'Close' button on a modal dialog. The reason is I don't want the user to accidentally close this partiulcar window, or at least display a confirmation to the user to ask whether if they really want to close it. I can't do that with the Form_Closing event as it stills closes it.

Set the Form.ControlBox property to false

Dear all,
I have been trying to send a string and read through Rs232 loop back null modem using the .net2 class serial port. The code is below:
the program sort of works but does not print "hello world", it prints the number 5, which is the byte size i am looking to print. i expected "hello" to print. any ideas as to where i am going wrong? many thanks.
void SendRs232Data()
{
serialPort->Open();
serialPort->Write("Hello World");
int offset = 0;//The offset in the buffer array to begin writing.
int count = 5; //The number of bytes to read.
array<unsigned char="">^ buffer = gcnew array<unsigned char=""> (10);//The buffer array to write the input to.
serialPort->Read(buffer, offset, count);
lblSerial->Text= (serialPort->Read(buffer, offset, count)).ToString();
serialPort->Close();
}
|
|
|
|
|
serialPort->Read(buffer, offset, count)
This function returns the number of bytes read.Since u have given the count value as 5,it would always return 5.Get the expected data from the buffer array
