for const TCHAR, you dont need CString::GetBuffer it supports LPCTSTR typecast.
and i don't prefer c-style cast of (const char*) because if it UNICODE build, (const char*) will still typecast wide char to char.

 Never use GetBuffer without knowing exactly what it does. Please check the documentation of this function and you'll see that it is wrong.
Furthermore, the CString class has an LPTSTR operator so, calling GetBuffer is totally useless.

OP provided code [^] is actually a old gold days' sample of exotic GetBuffer usage, a real gem for me and Mark. Thank you for highlighting.

guys,
i get some porblem. i degine a graph region and i have drawn some grids with the following codes.
BOOL CUserInterfaceDlg::PlotGrid(void)
{
int i;
GraphRegion->SelectObject(Brush);
GraphRegion->SelectObject(PenGrid);
GraphRegion->FillRect(&GraphRect,&Brush);
for (i=1;i<(GraphRect.Width()/2);i++)
{
GraphRegion->MoveTo(i*((double)GraphRect.Width()/30),0);
GraphRegion->LineTo(i*((double)GraphRect.Width()/30),GraphRect.Height());
}
for (i = 1;i<(GraphRect.Height()/2);i++)
{
GraphRegion->MoveTo(0,GraphRect.Height()-i*((double)GraphRect.Height()/30));
GraphRegion->LineTo(GraphRect.Width(),GraphRect.Height()-i*((double)GraphRect.Height()/30));
}
return 0;
}
then i tried to draw another line on the grid by the following codes:
BOOL CUserInterfaceDlg::PlotRunWay(void)
{
UpdateData(TRUE);
GraphRegion->SelectObject(PenRunWay);
RXArray[0]=m_AirXPisition;
RYArray[0]=m_AirYPosition;
RPoints[0].x=RXArray[0];
RPoints[0].y=RYArray[0];
RPoints[1].x=RPoints[0].x+30000;
RPoints[1].y=RPoints[0].y+200;
GraphRegion->MoveTo(RPoints[0]);
GraphRegion->LineTo(RPoints[1]);
return 0;
}
but this is not working. it just drawing the grid lines. can anyone tell me why it happening.
thanking you all,
shohel

Is that typo only here? Or in your programm too? (It looks like you copy-pasted the code snippet so check it in your app)

two simple program
i want compare between these two programs (in syntx and semantic)

hi ,
pls suggest me "THE BEST " book for mastering

ii)c++
thanks

Sorry,
I am sure I should stated how I declared my variables (just a quick finger)
char *my_ptr;
char *my_ptr1;
CONTEXT c;
I tried defining the variables both locally whitin the function and globally outside of the function with the same result
thankx again

I just looked at the previous message don't see any way to modify/edit it once it has been sent

Hi,
Dont know why but the Visual C compiler is not generating any code for the following
using Visual Studio 2008 Pro
c.ContextFlags = (CONTEXT_FULL | CONTEXT_CONTROL); <-- no code
GetThreadContext(hThread,&c);
my_ptr = c.SegFs; // Fs pointst to TEB <-- No code
my_ptr = my_ptr + 0x2c; // point to ThreadArray sotrage
(DWORD)my_ptr1 = *my_ptr; // point to first slot <-- No code
I move the code to some other soruce/DLL and did generate code for the statements in question
I tempted to go into _asm mode
thankx

just curious how do you verified. For Release mode I Assume.

Unreference variable my_ptr1, no use generating code. And just curious how do you able to compiled that statement.
ForNow wrote: c.ContextFlags = (CONTEXT_FULL | CONTEXT_CONTROL); <-- no code
constant data, try assigning variable data.
ForNow wrote: my_ptr = c.SegFs; // Fs pointst to TEB <-- No code
my_ptr = my_ptr + 0x2c; // point to ThreadArray sotrage
(DWORD)my_ptr1 = *my_ptr; // point to first slot <-- No code
compiler optimises to use (address of c + SegFs member offset + 0x2c). I think it is safe to use this without asm.

Thankx
thats it just ran Debug mode and it worked

Your final build should be release configured, i mean that code is safe in release build also, the compiler generates optimised code, it is still safe to run. what is the problem you face in release mode although the variable assignment is skipped in the optimised code.
if you want to disable optimisation for a region of code, use,
#pragma optimize( "", off )
.
.
.
#pragma optimize( "", on )

I'm using Visual C++ 6.0 MFC with SDI
I don't understand how to make the initial window size of my program equal to the full screen size instead of the smaller window that comes up.
Thanks ahead of time.
