Seriously - I am not so sure this variable =! variable is a proper C syntax anyway.
By itself it is a "logical NOT operator".
In this example the compiler (VC6.0) sees it as variable = !variable assignment.
(Space after = sign is “assumed”?)
Not too clear since if you write variable != variable it is interpreted as variable not equal variable as used in if(variable != variable) test condition.
A completely different operator!

Again - by itself it does not make any sense in if statement.

Would be nice to know if someone knows what the ANSI standard for C says.
I have not found "=!" in MSDN by itself.

Personally I would stay away from using it without space after the equal sign – it reads better.

=! is not an assignment operator

int some_variable;<br />
some_variable =! some_variable;

means assigning (! some_variable) to some_variable

NetJoinDomain-lm.h, lmjoin.h

Hi all,
I want to use NetJoinDomain function. It always ends by errors(89) in Lmjoin.h or Lm.h. I have linked netapi32.dll.

Here is one of 89 errors:

Error 1 error C2146: syntax error : missing ';' before identifier 'NET_API_FUNCTION' c:\program files\microsoft visual studio 8\vc\platformsdk\include\lmjoin.h 99

What am I doing wrong?

Thanks.

I think you've just included Lmjoin.h. It needs Lm.h also. Just include both as follows.

#include "Lm.h"
#include "lmjoin.h"

Me too had the same error by just including Lmjoin.h. Roll eyes | :rolleyes:

Regards,
Jijo.

Not quite. If you'll notice the errors are different.

Error 1 error C2146: syntax error : missing ';' before identifier 'NET_API_FUNCTION' c:\program files\microsoft visual studio 8\vc\platformsdk\include\lmjoin.h 99

Error 1 error C2143: syntax error : missing ';' before '__stdcall' c:\program files\microsoft visual studio 8\vc\platformsdk\include\lmaccess.h 46

it's now complaining about something in lmaccess.h so you've likely included the headers too high up in your stdafx.h file.

Make sure the includes are toward the bottom of the Wizard generated Include statements in stdafx.h to make sure the whole mess of other junk is in place before it attempts to include your api headers. Do a "rebuild all" to ensure everything gets taken into consideration.

// All wizard generated stuff should be above this
#include "Lm.h"
#include "Lmjoin.h"

i have 4 flex grids in my application. how can i use a single horizontal bar to scroll all the flexgrids together? i am aware that we can use scroll bars within the flexgrids. but i wnat it externally? please give me some leads

Where are those flexgrid placed ? In a view, on a dialog, ... ?
Basically, what you will have to do is handle to WM_HSCROLL and WM_VSCROLL messages that are set to the parent, move the grid accordingly and adapt the scrollbars correctly.

You'll have to configure the toolbars yourself (set the range, the size of the 'gripper', ...).

EDIT: you can check this article[^], it will give you some clues as what to do.

Getting cursor position in editbox and placing the text there???

Hi all,

I have a edit box and a button and on button click event i am placing a particular text in edit box.....

Now suppose if i am having "ab" in edit box and i place my cursor between a and b then after pressing button the text should display in between a and b.....(i.e i should get cursor position and whereever the cursor is the text should be appended there only)....

How can i do this....

Thanks in advance

You want to append text or insert text in the middle? They are two different things!

For appending, you could use GetWindowText() followed by a SetWindowText()

For inserting, you could use ReplaceSel(), as Cedric already pointed out.

Did you follow the link and read the information ?
Did you understand this sentence ?
If there is no current selection, the replacement text is inserted at the current cursor location.

Isn't that what you are looking for ?

Win32 Timer and a C++ Class?

Steffen Lange13-Jun-08 1:56

Steffen Lange

13-Jun-08 1:56

In a Win32 console application a timer should call a member function of a C++ class.
But how can I make the API function SetTimer to call this member function?

Thanks in advance.

Pass the class pointer as the argument of the timer callback function.

SetTimer() doesn't take a member function as an argument.

You can, however, use a static member function with the right signature:

class MyClass
{
...
static void CALLBACK TimerProc(HWND hwnd, UINT uMsg, UINT_PTR idEvent, DWORD dwTime);
...
};

You can pass &MyClass::TimerProc to SetTimer().

Why is that a problem?

You can pass a function pointer, it just can't be a non-static class
member function.

If making the method static is the problem, you could use a multimedia timer[^]
instead. The multimedia timers let you have a pointer passed to
the callback which you can cast to a pointer to an object of your
class...

class MyClass
{
...
   static void CALLBACK MyTimerProc(UINT uID, UINT uMsg, DWORD_PTR dwUser, DWORD dw1, DWORD dw2);
...
public:
   void SomeFuncThatCreatesATimer();
};

void SomeFuncThatCreatesATimer()
{
...
   ::timeSetEvent(..., ..., &MyClass::MyTimerProc, this, TIME_PERIODIC);
...
}

void CALLBACK MyClass::MyTimerProc(UINT uID, UINT uMsg, DWORD_PTR dwUser, DWORD dw1, DWORD dw2)
{
   MyClass *pThis = (MyClass *)dwUser;

...access non-static MyClass members using pThis...

Dialog window help

Using Visual C++ 6.0 MFC in SDI application

I have a view that includes a dialog window from which the user can select different options. I do not want the user to be able to close that window. When the view changes, that dialog window will close automatically. However, I noticed that when the window is displayed, if the user hits the "escape key" esc, the window disappears. How do I prevent that from happening?
Thanks
