actually that name is part of String Table you have to edit that!

For this, In my knowledge there is no way. I think, you need to follow path suggested by Paresh.

Q. To change the SDI application mainframe name ?
A. In the resource string table, change the value of IDR_MAINFRAME resource id.

Q. To change the name of exe file ?
A. Go to "Project | Settings | Link" tab. Category -> General. Edit "Output file name".

SetScrollRange has a limit?

Hi there,
I have a CWnd custom control and and i set the scroll bar range by using SetScrollRange in OnPaint function.

this->SetScrollRange(SB_HORZ, 0,110000, TRUE);

However, i notice that by a certain range, the diagram the is shown at the beginning of the scroll position repeats itself. And when I scroll further, it will also repeat the same thing again.
Why does this happens?

Thanks for any help

yes it has a limit.

(from MSDN)
The difference between the values specified by nMinPos and nMaxPos must not be greater than 32,767. The default range for a scroll-bar control is empty; that is, both nMinPos and nMaxPos are zero.

I've notice that if i drag the scrollbar using mouse, the diagram will repeat itself when it reaches a certain range. However, if i click the scrollbar button (which looks like this "[>]" to the left), it can scroll to a larger range but it is too slow if i wan to scroll fast to a certain range. Sometimes when i need to scroll fast,i normally drag the scroll bar to achieve this. However, i also need to be able to scroll slowly by clicking on the scrollbar button. Any suggestion on how to be able to scroll fast and slow whenever needed?

Instead use ShellExecuteEx. And use SHELLEXECUTEINFO-->nShow to hide the window,

e.g
SHELLEXECUTEINFO ShExecInfo;
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
//initialize other parameters to your need
ShExecInfo.nShow = SW_HIDE;
ShellExecuteEx(&ShExecInfo);

Havn't you seen Note in MSDN documentation for this API ?
Note This function is provided only for compatibility with 16-bit Windows. Win32-based applications should use the CreateProcess function.

CreateProcess(), WinExec(), ShellExecute() are ok

system() works, but exists for backward compatibility with 16bit applications. you shouldn't use it

Trapping sleep/hibernate start and stop from Code

Simon Blundell26-Feb-07 13:38

26-Feb-07 13:38

Hi, I have a VC6 program that includes heavy use of serial communications. My problem is that when a serial connection is live and the computer enters sleep mode the computer becomes unpredictable - freezing when sleep is intiated, or refusing to come out of sleep mode.
If I first manually close the COM port(s) then let the computer go to sleep (or hibernate) then everything works as expected.

So my question is, is there any way I can detect when sleep (or hibernate) mode is being entered from code in my program (so I can force a close of the COM ports)? And similarly to identify when the computer is waking up (so I can reopen the COM ports)?

Appreciate any help...
Simon.

3D Objects

Is there a way to import an object created with a 3d-modeling program (ex. Google Sketchup) to an OpenGL application and use it?

If yes what file type must it be (.obj?) and how?

I'm new at this Smile | :)

Try asking this on the graphics forum. I don't know about openGL but I know Direct3D has adapters/plugind/convertors for many of the popular 3Dmodelling softwares file formats. I'm sure OGL has the same.

I'm calling:

Graphics.SetSmoothingMode(Gdiplus::SmoothingModeAntiAlias);

but still it doesn't work. My Metafile object is drawn without antialiasing.

Does anyone know why?

Conversion of Unsigned __int64 to binary does not work in 2003

AAKAra26-Feb-07 9:02

26-Feb-07 9:02

Hello,
I am doing a conversion of a unsigned --int64 to binary using 2003 and does not seem to work. This code works with VC++ 6.0.

In My header file i define a structure

#define QWORD unsigned __int64
#define NUM_EVENTS 53
struct SList // sl
{
int idObject;
int EMPTY_OBJECT_ID;
BOOL aEvents[NUM_EVENTS];
SList() : idObject(EMPTY_OBJECT_ID)
{ ::memset(aEvents, 0x00, sizeof(aEvents)); }

SList(int id) : idObject(id)
{ ::memset(aEvents, 0x00, sizeof(aEvents)); }

SList(int id, QWORD qwEnabled)
{
SList();
idObject = id;
for (int i = 0; i < NUM_EVENTS; i++)
aEvents[i] = 0 != (qwEnabled & (QWORD)(1 <<
(QWORD)i));
}
};

In My cpp file i am populating a temporary list,

int id =12345;
QWORD qEnable = 9007191738548223;
CArray <SList*, SList*> aSList;
SList* psl = new SList(id, qEnable);

// Add them to a temporary list.
aSList.Add(psl);

Anyone having any idea whether there is any patch to rectify? Pls help
