I have a problem:
I declare a variable CString string; in Class1.
During the execution of Class1 I give a value to this variable
string = "hello";
After on Class 2 I declare a pointer to the Class1:
Class1* pClass;
pClass = Class1;
Now I want to utilize the value stored in string
AfxMessageBox(pClass->string);
But the messagebox show empty.
It's the same if I don't use a pointer:
Class1 newClass;
AfxMessageBox(newClass.string);
But If I make
pClass->string = "bingo";
AfxMessageBox(pClass->string);
BINGO!
What's up?
COnsider that Class1 and Class2 are both running at the same time, on two CFrameView.
I set to display AfxMessagesBox in the costructor and destructor of each class, so I know what's running at what time.
But why when I call the variable string from Class2 it's lost its value.

Can you please post your code? Because the snippet above will show an error message during compile, I think.

Ok sorry:
CLoginForm* pLoginForm;
pLoginForm = new CLoginForm;
AfxMessageBox(pLoginForm->szString);
delete pLoginForm;

using VC++6 ,i can easily rename the member variables of CRecordset-derived class with classwizard,
but when i use VC++7 ,i cannot find one easy way to rename the variable which appears at several place in .cpp and .h file.
i want to know : is there any tool in VC7 which can update columns and bind the member variables to columns in the database table like classwizard in vc6?
anybody have some advice appreciated anyhow.

What messages you want to recieve and what is your child window? A dialog? Or a button?

How can i achieve that in my program,
wat's the function or API to do this?
I don't need it to be able to resize using mouse, just rather by function calls will do.
And how do i propogate the message from CDialog to the controls in the dialog boxes?
like WM_SIZE or any another msg.
Thanxs a billion.

Use either SetWindowPos or MoveWindow. What message do you want to propogate? Because ususally the controls are resized in the WM_SIZE message of the dialog box.

Thanxs once again

the int and bool data types are native data types that you will find in C++. The int is a four byte signed integer and I believe that the bool is a one byte value that indicates either true or false.
Microsoft has declared the INT and BOOL datatypes to make programs more portable. If you search through the header files in windows.h, you will find that the INT is probably defined as an int like this:
#define INT int
And the BOOL is defined as an int as well. That is because the bool datatype does not exist in C, and all of these functions are supposed to work in C as well as C++.
The code is made more portable by letting you define what the underlying datatype is for the INT or BOOL when you compile the program on different machines. For instance the difference between compiling your program for Win32 or Win64. Or an Intel machine or a UNIX machine.
I prefer to use the native datatypes for my own internal code, but if I am writing a library of API functions to distribute, I usually use the #defined types.

You dont need to do that, if you change the size of the controls from the dialog(eg. MoveWindow), the control will recive a WM_SIZE message.

I am getting error LNK2019, after adding this code to a project:
void CSimpleShlExt::DeleteFiles(string sPath)
{
vector <string> Paths;
string enumerate = sPath;
if (enumerate[enumerate.length()- 1 ]!= '\\')
enumerate += '\\';
enumerate += "*.*";
WIN32_FIND_DATA fd;
::FindFirstFile(enumerate.c_str(), &fd);
}
and I think I need to get rid of ATL_MIN_CRT, which is defined I believe, but I cannot find where. I am using .NET. Can anyone help me ?

actually, removing this code does not solve the problem, but it now fails to build with the code that originally compiled fine. So my project settings must have changed, but how to change them back ?

In VC 6 _ATL_MIN_CRT is set in the Project Settings->C++ tab->Compiler options. No idea where it is in VC 7 'cause I never could find the bloody project settings in that version.  If worse comes to worse, put this in stdafx.h:
#undef _ATL_MIN_CRT

Thanks Mike. you're not wrong - the new IDE blows when it comes to this stuff. It's like XP - it tries to help, but merely makes things impossible.
It works now though

"nafxcwd.lib" and "LIBCMTD.lib" both defined "delete", I need to use both of the two lib files. If I choose using MFC in static lib, a error will come out.
What can I do? Thanks!

I have the following
dataout.setf(ios::fixed | ios::showpoint);
dataout << setw(10) << setprecision(5) << number << endl;
I get this result:
0.00000
How can I make it print instead:
.00000
Or, if I have the output:
-0.12123
How can I make it remove that 0 and print:
-.12123
Sounds really stupid I know, I have to make this data perfect in
order for it to work with this crappy fortran program.
Please, any response anyone can give me will be greatly appreciated.
Sincerely,
Danielle (an overworked graduate student)

sprintf() it o another string first and remove the zero manually then output the adjusted string?

I've tried OnOK() but that only works in a Dialog. OnDestroy() and DestroyWindow() dont work either, and I dont know what else there is. Whats the function to close my program?

Try this:
PostQuitMessage(0);

This might kill the application unless there are other GUI threads. It's safer to post a WM_CLOSE to the window you want to close.
