CString sa[10];
_variant_t var;
...
CString s=(LPCTSTR)(_bstr_t)var;
sa[0]=(LPCTSTR)(_bstr_t)var;
It got a runtime error. Why? And how to do it properly?

Are you initialising var?
Why do you need to cast var to a _bstr_t type? (i.e. cannot you initialise and use directly a _bstr_t variable?)

Why all this casting? There is a CString constructor that takes a variant.

here is the "afxapi"define or the "afxwininit"?

AfxWinInit.
the AFXAPI macro is defined as
#define AFXAPI __stdcall

While going through C++ object model book by Stanley Lippman, I came across a statement "inline functions have static linkage"
Now if inline function code is expanded into the source where it is used, then this statement is perfectly correct.
But if the compiler is unable to replace this function call with appropriate code, then it will behave like ordinary function call.
So I tried declaring and defining this function in a header file inside class.
// a.h
class ABC
{
public:
void MyInlinefunction()
{
// some code which forces this function not to be inline
}
};
When I analyzed assembly code of my 2 source files where this header is included.
b.cpp,c.cpp.
I found two instances of the same function(MyInlinefunction) in two source files. Is this behavior is correct?

No. At least IMHO: if they are expanded there is no standard function in the corrensponding code.

Yes, this correnspond to static linkage.

So How linker handle this situation ?
|
|
|
|

I think that's not a linker problem, the static behaviour is resolved by the compiler and , in the end, there is only one function in the executable, called by both sources.

I don't think the compiler can optimize this. because when this files are compiled separately and object files are linked together. Linker has to do the rest work.
|
|
|
|
|
Well, you're right. Each of the two object files contains a definition for MyInlineFunction, hence must be the linker to do the magic and I don't know why...

Hi all,
I've create a window as follows,
void CRtf::Initialize(void)
{
HWND m_hwnd_RTFBox = CreateWindowEx(
WS_EX_APPWINDOW,
RICHEDIT_CLASS,
"RichTextWindow",
WS_BORDER|ES_MULTILINE,
0,
0,
100,
100,
::GetConsoleWindow(),
NULL,
0,
NULL);
}
After doing all the process, I've destroyed the window as well.
My question is this. I use the above handler iteratively within a loop. So all the time call the Initialize() in each processing step. Simply create and destroy to the equal number of looping process. I want to avoid it.
According to the MSDN, if the CreateWindowEx() is succeeds, the return value is a handle to the window. If it is failed the return value is NULL. So I've tried something like this.
while(m_hwnd_RTFBox != NULL)
{
}
But it doesn't work. Can you guys give me a clue on this.
I appreciate your help all the time...

How bad me. I can do it within Constructor and Destructor.

Hi,
I'm starting to programm apps for PPC 2003 using VS 2005 and I have a strange problem, when I have a normal empty window and i press the return key the window closes as it I head used the close button.
Why is it so and how can i solve this ina clean and decent way?
btw: how can I change the close OK button to the normal one with the X?
Happy New Year

The links you'v posted does not apply to my problem, because thay are for normal windows APP's but I have a Pocket PC app, there are no default buttons created.
The secund link points to a possible solution, but i think there must be a one special for PPC's that may fit much better

I already figured out a similar workaround using OnCommand, but I have than the problem that than also the Enter Key does not work any ware, when I intercept the return key in OnCommand it is not passed to OnChar, or else, i assume PreTranslateMessage will have the same problems.
The only thing bypasses the interception is OnKeyUp, OnKeyDown seems to dont work at all on PPC 2003 for the enter key.
I'm looking for a realy clean solution.

Seems to work better than OnCommand,
OnKeyDown is triggerd properly but with nChar == 0, but this is a minor problem and can be easly handled.
thx.

From where i can look at the OnMouseMove Flags for the some mousemove events.
