I want to test one of M$ examples,"Starting an Interactive Client Process".At the begining of it,there is these lines:
#define DESKTOP_ALL (DESKTOP_READOBJECTS | DESKTOP_CREATEWINDOW | \ DESKTOP_CREATEMENU | DESKTOP_HOOKCONTROL | \ DESKTOP_JOURNALRECORD | DESKTOP_JOURNALPLAYBACK | \ DESKTOP_ENUMERATE | DESKTOP_WRITEOBJECTS | \ DESKTOP_SWITCHDESKTOP | STANDARD_RIGHTS_REQUIRED)
#define WINSTA_ALL (WINSTA_ENUMDESKTOPS | WINSTA_READATTRIBUTES | \WINSTA_ACCESSCLIPBOARD | WINSTA_CREATEDESKTOP | \ WINSTA_WRITEATTRIBUTES | WINSTA_ACCESSGLOBALATOMS | \ WINSTA_EXITWINDOWS | WINSTA_ENUMERATE | \ WINSTA_READSCREEN | \ STANDARD_RIGHTS_REQUIRED)
Whenever it use DESKTOP_ALL and WINSTA_ALL,I got "C2017:illiegal escape sequence".I have to delete \ there to get rid of this error,Could anybody please tell me about this charachter here?

It looks like the original code was
#define DESKTOP_ALL (DESKTOP_READOBJECTS | DESKTOP_CREATEWINDOW | \
DESKTOP_CREATEMENU | DESKTOP_HOOKCONTROL | \
DESKTOP_JOURNALRECORD | DESKTOP_JOURNALPLAYBACK | \
DESKTOP_ENUMERATE | DESKTOP_WRITEOBJECTS | \
DESKTOP_SWITCHDESKTOP | STANDARD_RIGHTS_REQUIRED) and got reformatted. Putting a backslash at the end of a line makes the preprocessor join that line and the next into one big line. You usually only see this with huge macros, like your examples.

The \ character is usually used for putting newlines and tabs into strings (\n & \t), I can't see why they should be in those two #defines though but admittedly I've never had to use them.

Like Mike said, if the last line of a macro is a \, then the macro spans the next line also

if i Write a code that it Creats a CWnd Object in the main Window, how can i capture the mouse event in it ??? i know that this CWnd object has the Function onMouseMove or onLButtonDown or other Functions for Mouse Events but how can i trap them ???
when i move the mouse over that CWnd Object the Focus Set to this object.and in return the Mouse Event of the main window will lose. but it must be exist a way to capture the Events of the Focused window.
I am realy confused 
Here is Code:
//When i Right Click CW Creats.
//CW is a Member Variable of the class
void CMyTestView::OnLButtonDown(UINT nFlags, CPoint point)
{
CW=new CWnd;
CW->Create(NULL, "",WS_VISIBLE|WS_CHILD|WS_CLIPSIBLINGS ,CRect(0, 0, 26,26), this, 0xffff);
}
|
|
|
|
|
CWnd* p = GetParent();
if (p) p->SendMessage(...);

When I use printf to display a double variable it gives a wrong result, but when I turn to use a cout to do the same thing it just did it right. For example:
...
double getValue()
{return value; // value is a double variable}
...
printf("%d\n", getValeue()); // gives a incorrect result
cout << getValue() << endl; // right
What are the differences between these two methods? Thanks!

What do you mean by incorrect?
How about an example of the output.

The problem with the first one is that %d is for ints only, you should use something like %f. Or maybe thats just my hungover brain thinking poo again

LOL, silly me. I didn't notice that.

%d is the format spec for integers. Use %lf for a double (think "long float").

ummmmm
printf("%d",value);
is for integer values
try printf("%f",value);
for floats or doubles

You are not using the correct format code in the printf. Try something like this:
double x = 123.456;
printf("This is x: %lf\n",x);
should print the following:
This is x: 123.456 Your original code used the %d format, which is used for int's.

If you have VC7 Enterprise (not sure about other versions), you have a minimal version of Install Shield with it.
Otherwise you could look at Inno Setup (its free)

I suggest you using NSIS, it is a great free installer. You can get it here

I used SetWindowRgn(hWnd, hRgn, true); to make part of a window transparent, however, this transparent part of the window is not receiving any mouse message. is it possible to accomplish what I want(receiving mouse message on the invisible part)?
thanks
|

SetWindowRgn does not do transparency, it changes the physical shape of the window. If you make a window round, for example, the parts outside the circle (but inside the original rectangle) are no longer part of the window, period, so the window won't get messages relating to those parts.. To do what you want, you need to use 2K/XP and use layered windows.

If i call a dialog in Modal form, and it has a few functions defined in it, How can i automatically call the functions when the dialog box opens? Where should they be called? For example, i have a function defined as PlotData(), where/how would i call this function to execute it when the dialog is opened.
Cheers
Ayush.

Get OnInitDialog to call them, or OnCreate.
Of course, PlotData should be part of OnPaint.
