From MSDN, SetCursor reference
If your application must set the cursor while it is in a window, make sure the class cursor for the specified window's class is set to NULL. If the class cursor is not NULL, the system restores the class cursor each time the mouse is moved.
you may also change the class cursor of your window:
SetClassLong( hWnd, GCL_HCURSOR, (LONG)LoadCursor(NULL, IDC_ARROW));
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Another thanks man!
Where do you suppose I include this line of code, in 'OnInitialUpdate' of my view?
Thanks.
P.S.
I included this line:
SetClassLong( this->m_hWnd, GCL_HCURSOR, (LONG)LoadCursor(NULL, IDC_ARROW));
at my view-s OnInitialUpdata and still no change, my cursor still reset from hourglass to arrow when I move the mouse!

Nope. You need to change your SetCursor(... lines with corrensponding SetClassLong(... ones.
Good luck.

Hi
i have one c++ source code.This code was good compiling in windows XP (The output of the code was return value '0')
and then i was changed into windows Vista its also compiling but it gives the return value '255'..
i am using the compiler visual studio 2005
i dont know not much of idea this problem ...

What function returns you '0' or '255'?

Thanks to your replay ...
HRESULT datatype function retun in 0 (in XP) and 255(in vista)

You have two different options:
1. Hard-code your function to return 0 always.
(or)
2. Let us know what is the 'function' that you are talking about, why should it return 0 and not 255, show us any relevent piece of code, why would you still want to continue programming, etc.,
Nobody can give you wiser advice than yourself. - Cicero

Hi this is my sample code .
STDMETHODIMP CFileIO::VerifyUser(SAFEARRAY* userCredential, SAFEARRAY* appCredential, BYTE* result)<br />
{<br />
*result = (BYTE)false;
try<br />
{<br />
validateCredential(appCredential);<br />
validateUser(userCredential);
*result = (BYTE)true;<br />
}<br />
catch (std::exception& e)<br />
{<br />
log("Verify User", e.what(), EVENTLOG_ERROR_TYPE);<br />
}<br />
return S_OK;<br />
}
#define S_OK ((HRESULT)0x00000000L)//winerror.h
#define S_FALSE ((HRESULT)0x00000001L)//winerror.h
return S_OK ;
return S_FALSE;
this is perfectly running in windows XP and it gives return value '0'but in vista it running good but it gives the retun value 255.
whats the problem about that?

The problem is that you are not showing what function is returning 255. VerifyUser() returns either 0 or 1.

Actually in Windows Xp in this source code successfully compiled with return value '0'.But in vista its successfully compiled but it gives return value '255'.This is the problem.

Indeed, since you have not shown any code that returns a value of 255.

1. I have created a MFC single dialog based project
2. I have inserted Microsoft WebBrowser Control Activex
3. I am now able to open any web pages
But i can't suppress the javascript error. I have seen after inserting this activex control it has created a class CEXplorer1.
On VB i can set a property name suppressScript error but i can't find any property when i am using VC++ and MFC.
I am using visual studio 2005in windows XP with service pack 2 and have internet explorer 6.0
I have seen some tutorial they are saying i have to implement IOLECOMMANDTARGET::EXEC()
i want some simple solution if possible.

Hi,
I would like to use the RAS implementation in Win XP to make a dial up to my ISP and to establish the PPP link between my laptop and PDA phone.
I cannot use RASDial as the phone is not recognized by Win XP as a hardware connected even though the 2 devices are linked using Bluetooth.
I read that using RasCustomScriptExecute allows me to dial out through a specific com port. I would like to seek for assistance on some samples to get me started, as the MSDN examples are not enough for my understanding.
Thanks and regards,
PS

Hi,
Anyone know whether Open button in a MS office Open file dialog is a "BUTTON" or not. Why the spy++ is also not identifying it as a window? . And if it is a button it implements all button messages such as BN_CLICK etc.
thanks

Hi,
I have a function in which I am passing to a character pointer (char *) by reference e.g. make_num(char *& str)
the first data variable I declare in my Function is a 255 byte character array e.g. char hold_area[255}
So my my code looks like this
Make_num(char *& str)
{
char hold_area[255]
When I refrence the address of the begining of thiis area e.g. &hold_area[0] it seems to be off by 4 bytes meaning when I look at the actual address in code hold_area[0 - 3] has some value maybe a pointer where my actual data starts in hold_area[4] ???
I prototype make_num( char *&); ???
A compiler glitch ???
thankx

How do you copy str to hold_area?

Its a = assignment e,g,
if ((char *) dtr >= 0x30 || (char) *str <= 0x39)
hold_area[i] = (char) *str
Hey just had a thought when I looked at the assembly code this data was referenced by the ESP reg
If I am calling by reference then there is no need to push to variable on the stack
maybe I should declare make_num with stdcall (I think ??) I am going to have to test this out
thankx

with bad casts like that, I wouldn't be surprised if a pointer gets
written to your char array

Something must of happened when I cut and paste the code as I missed to * beforte str
However here is my code
{
if((char) *str >= 0x30 || (char) *str <= 39)
{
holdstr[i] = (char) *str;
i++;
}
}
holdstr[i] = NULL;
number = atoi((const char *)&holdstr[0]);
Is there any special calling method I need when calling by reference e.g stdcall/fastcall as it seems that the ESP reg is not pointing to where it should on entry
Thankx

hmmm....I'm not sure why you are expecting a certain esp value.
If there was a compiler bug with this, then I bet millions of apps
would be affected, and I, for one, couldn't trust local character arrays at all.
The implementor of the compiler is free to use the stack (or whatever other memory it wants to use)
for local variables in any way, as long as when we use the proper C++ syntax, we get access to the data
in a way the C++ specification states we should.
That aside, do you have a complete function example you can post along with
what you're seeing and what you're expecting to see with the esp register?
I'd be happy to look at it

This only happens... the bug in my release version of the the DLL when I run my debug thru VS its fine
Just so I understand the ESP or Stack pointer points to the Top of the Stack which has the paramters
to the functions afterwards are the Local Varibles of the Function
Global Variables are pointed to by the data segment register
(I am a Mainframe Assembler programmer by trade) knowing Assebmler or X6 Masm I guess helps especially when
There is a bug only in release version of the app as that seems to be the only way to see the values of the
Variables
Below is the Function.... This the fuction definition --> int make_num(char *&);
int make_num(char *& str)
{
char holdstr[255]; // allocate a large buffer
int i =0, number;
for (; *str != ','; str++)
{
if((char) *str >= 0x30 || (char) *str <= 39)
{
holdstr[i] = (char) *str;
i++;
}
}
holdstr[i] = NULL;
number = atoi((const char *)&holdstr[0]);
return number;
}
Thanks much

---> holdstr[i] = NULL; This is the culprit how come this statement didn't generate any MASM instructions ??
number = atoi((const char *)&holdstr[0]);
0037147D lea eax,[esp+4]
00371481 push eax
00371482 mov byte ptr [esp+esi+8],0
00371487 call dword ptr [__imp__atoi (37204Ch)]

Thanks!
The stack frame on entry to the function should look something like this
(after the stack frame is built, working downward in memory):
4 bytes: Passed reference argument (passed as a pointer probably)
4 bytes: Return address
256 bytes: local array
<--- esp points here
The compiler is free to align the local variables and add any integers
or whatever it needs for the stack frame, so to rely on a certain esp value
would require knowing exactly how the compiler builds the stack frame, which
will vary between compilers and compiler settings.
That aside, you found the culprit. I'm not sure why the code to add the null terminator
wouldn't be in the compiled code!
Maybe try this - add symbolic debug info to your release build configuration.
Then when you run it in the debugger you can still debug easy.
adding debug symbols to release builds[^]
Also for what it's worth, you can simplify this line:
number = atoi((const char *)&holdstr[0]);
to
number = atoi(holdstr);
I'll take a look at it here - please let me know what you find!
