If yo want to do it in your view class you can do it in OnInitUpdate()

Or if you are in Dialog, do it in OnInitDialog
Or, if you are in generic CWnd, you can try to do it in OnShowWindow, checking that the command is SW_SHOW and GetSafeHwnd() returns you not null and then query the database. Remember to have some flag, for example a static boolean variable inside function, then, after query, set it to false, e.g.:
...
if(GetSafeHwnd() != NULL){
static bool bFirstTime = true;
if(bFirstTime){
bFirstTime = false;
}
}
Hope this helps

Yes, WM_PAINT is no good place to stuff code in.
Register our own message and when you window is beeing created, post
it to yourself and the do the proccessing in response to the message.
If it's a dialog post it in WM_INITIDIALOG, if its a window post it in WM_CREATE.

BOOL CDlg::OnInitDialog()

CDialog::OnInitDialog();
CenterWindow();//???????????
return TRUE;
}

You can set the flag "Center" in the properties of your Dialog ("More Style" Tab).

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.

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.

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 ?
