Hi
I have this dialog where the size can be adjusted.
So i've written some event handlers to handle the messages (vscroll, size & hscroll).
This works very good.
But what if the dialog is already too big to fit into the screen!?!!. Then there have to be scrollbars already.If i resize the dialog, then there are some scrollbars but at default not.
How can i work around this? or has anyone written a class derived from CDialog which implements automatic scrollbar options.
Greetings

If I use the NM_CLICK event to do a chkBox.GeCheck() (for a listCtrl)soon as I check the box, it claims that check is FALSE. When I check the second item, the first checkbox is stated to have been checked by the debugger. SO basically the checkmark seems to apppear AFTER the NM_CLICK is triggered. So what message do I want to handle to detect instantly that the checkbox got checked in the listCtrl?
Thanks,
ns

Perhaps LVN_ITEMCHANGED? (Guessing)

The easiest way (to get the URL that IE is using) is to use Internet Explorer Automation (search MSDN for examples of using automation). However, if multiple IE windows are open, you'll need a way of determing which one the user wants to send.

What are you using to verify this? I tried this and used Spy++ to see the messages. The application received multiple WM_SETFOCUS messages.

Because CView has the focus of the OS.
From MSDN Library
-----------------
The WM_SETFOCUS message is sent to a window after it has gained the keyboard focus.
The SetFocus function sends a WM_KILLFOCUS message to the window that loses the keyboard focus and a WM_SETFOCUS message to the window that receives the keyboard focus. It also activates either the window that receives the focus or the parent of the window that receives the focus.
If a window is active but does not have the focus, any key pressed will produce the WM_SYSCHAR, WM_SYSKEYDOWN, or WM_SYSKEYUP message. If the VK_MENU key is also pressed, the lParam parameter of the message will have bit 30 set. Otherwise, the messages produced do not have this bit set.
By using the AttachThreadInput function, a thread can attach its input processing to another thread. This allows a thread to call SetFocus to set the keyboard focus to a window associated with another thread's message queue.

We are using the 'Crystal Report Control 4.6' as an OLE component in VC++. While using the SetAction() function provided by the OLE component, we are getting an error "Unable to load Report".
If some one has worked on the same or has any idea how to rectify the error please respond. Thanks

I am developinng a MDI application.
Wanna know if there are ways to record how many windows
were open last time when you close an application.
Just like photoshop.

I am not sure your question.
Do you wanna restore all windows opened last time when you run your application again, or just record the number of windows.
For the latter one, you can write this as a key into your ini file or registry before you destory all your windows.
Nice to learn

Hi,
Can we use the BOOL and bool interchangebly in a VC++ code.
That means can true and TRUE be used interchangebly?
I have a piece of code, working fine but using false for a BOOL variable.

BOOL is a Windows typedef, 4 bytes long. Its values are TRUE and FALSE.
bool is a built-in C++ type, 1 byte long. Its values are true and false.
That's all you need to know. Don't mix them. Sure, if you write:
BOOL b = false;
it will work, but it also looks like you don't know the difference between BOOL and bool. If you write this during an interview, it will reflect unfavorably on you.

BOOL
====
typedef int BOOL;
bool From MSDN Library
=======================
In Visual C++4.2, the Standard C++ header files contained a typedef that equated bool with int. In Visual C++ 5.0 and later, bool is implemented as a built-in type with a size of 1 byte. That means that for Visual C++ 4.2, a call of sizeof(bool) yields 4, while in Visual C++ 5.0 and later, the same call yields 1. This can cause memory corruption problems if you have defined structure members of type bool in Visual C++ 4.2 and are mixing object files (OBJ) and/or DLLs built with the 4.2 and 5.0 or later compilers.

Right now, I'm doing this:
CPaintDC dc(this);<br />
CBrush brush(RGB(255,0,0));<br />
HBRUSH oldbrush=(HBRUSH)dc.SelectObject(&brush);<br />
...<br />
dc.SelectObject(oldbrush);
It works, but there's a HUGH memory leak.  If I remove the SelectObject() lines, there's no leak anymore, so I assume that it's the SelectObject(), or the Brush maybe. But objects are destroyed at the end of the scope, no?
Is there another solution that guarantees complete release of resources?
