I have a CString of 6 numbers how can i cast into one int variable so i can compare it with different numbers.

int i;
CString str = "32";
sscanf(str, "%d", &i);
ASSERT(i == 32);
TOXCCT >>> GEII power

One more thing...
can i do this without the Assert coz i don't know the value of str in my program
thx anyway

certainly, ASSERT() was just here to show you that aftrer treatment, the int contains the string's value...

an array of 1,000,000 elements of 6 digit each? __int16 is too short so __int32.

From the msdn website: "Note that the __int8 data type is synonymous with type char, __int16 is synonymous with type short, and __int32 is synonymous with type int". However, if you use MS VC++ on windows, the max integer value you can use with int is 32,767 if signed or twice that if unsigned. What you need is a long int that can take 2,147,483,647 or twice that if unsigned. If you need bigger values then __int64 works... partially... there seems to be a whole lot of things that are not supported for that data type in C++ but seem to work fine in C.

__intN[^] are platform independent data types, they are synonims for the ANSI data types.

I have a problem with printing.
When I print image it's very small on paper, but big on the screen.
So I decide to add code:
int logxPrn=GetDeviceCaps(hPrinterDC,LOGPIXELSX);
int logxScr=GetDeviceCaps(hDisplayDC,LOGPIXELSX);
But this values are same.Why?
int logxPrn=GetDeviceCaps(hPrinterDC,HORZRES);
int logxScr=GetDeviceCaps(hDisplayDC,HORZRES);
This values are too same!!!
Can Anyone Help me?

I had a similar problem that required me to use something like:
SetMapMode(hDC, MM_ISOTROPIC);
SetWindowOrg(hDC, bitmap_width / 2, bitmap_height / 2);
SetViewportOrg(hDC, GetDeviceCaps(hDC, HORZRES) / 2, GetDeviceCaps(hDC, VERTRES) / 2);
SetWindowExt(hDC, bitmap_width, bitmap_height);
SetViewportExt(hDC, GetDeviceCaps(hDC, HORZRES), GetDeviceCaps(hDC, VERTRES));

DavidCrow Can you explain me
How to use your code and how it works?

Are you using MFC?

Then put this code in the view's OnPrepareDC() method after calling the base implementation:
if (pDC->IsPrinting() != FALSE)
{
pDC->SetMapMode(MM_ISOTROPIC);
pDC->SetWindowOrg(m_BmpInfo.bmWidth / 2, m_BmpInfo.bmHeight / 2);
pDC->SetViewportOrg(pDC->GetDeviceCaps(HORZRES) / 2, pDC->GetDeviceCaps(VERTRES) / 2);
pDC->SetWindowExt(m_BmpInfo.bmWidth, m_BmpInfo.bmHeight);
pDC->SetViewportExt(pDC->GetDeviceCaps(HORZRES), pDC->GetDeviceCaps(VERTRES));
}

Hi all,
I have created a setup for an application. When I perform an upgrade operation using this setup, currently the logon information is read from a file(setup.inf). It includes username, password, servername and database name. Now I don't want to depend on this setup.inf file. Instead at the time of upgradation, the setup should read this information from the DSN already created. If anyone knows how to do this then please tell me.
Thanking You.
Regards,
Harshad

System DSN are stored in the registry at HKEY_CURRENT_USER/SOFTWARE/ODBC/OBBC.INI
youc can read the DSN named key.

Hi
I have a TabCtrl. The user should finish the operation on Tab 1 (press a button in the tab 1) before being able to access Tab 2 and the others.
How can i make this restriction?
