I found another way around this. I have existing build .res files and I was wanting an easy way to link to them to pull it into the statically built .exe. I was hoping the pragma comment stuff could pull this off. The reason I thought this might work was because you can feed in various .lib or even .res files into the "Object/Library modules" edit in the Link settings, so I was hoping pragma comment (lib,...) would do the same trick.

I had the same problem. I've manually added refences to the source .rc files via the 'Resource Includes' dialog 'Compile-time directives' by adding lines like: '#include "path/res.rc"'.
So between libs i've had to add these statements as needed (i.e. one lib/dll uses resources from another), as well as in any final .exe. It's a pain, but i think the Resource Includes - Compile-time directives is the 'documented' way to do it.
By adding the #include .rc you also make it a dependent, so no risk of the .res being out of date.
How did you end up doing it ?

The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

Hi there,
I am trying to populate a combo box of available com ports.
I call my openSerialport function from my init dialog function but as soon as CreateFile is executed I get an Unhandled Exception error which has the info 0xC0000005 : Access Violation.
Can anyone help???????
Code Below
InitDialog call
BOOL CPTZControlDlg::OnInitDialog()
{
int i, j, hr;
char portStr[7];
CDialog::OnInitDialog();
SetIcon(m_hIcon, TRUE);
SetIcon(m_hIcon, FALSE);
j=0;
for (i=0 ; i<PORTNUM ; i++)
{
hr = m_serialCtrl->OpenSerialPort(i,0);
if (hr == 0)
{
g_exists[i] = 1;
g_nComPortInd[j] = i;
g_comport[i] = j;
j++;
sprintf(portStr,"COM%d",i+1);
m_comPort.AddString(portStr);
}
else
g_exists[i] = 0;
}
return TRUE;
}
Open Serial port function
int CSerialControl::OpenSerialPort(int pcCommPortInd,int radd)
{
DCB dcb;
BOOL fSuccess;
char pcCommPort[14];
int m_nComPort;
m_nComPort = pcCommPortInd;
sprintf(pcCommPort,"COM1",pcCommPortInd+1);
m_hCom = CreateFile( "COM1",
GENERIC_READ | GENERIC_WRITE,
0,
NULL,
CREATE_ALWAYS,
FILE_FLAG_NO_BUFFERING | FILE_FLAG_OVERLAPPED,
NULL
);
if (m_hCom == INVALID_HANDLE_VALUE)
{
m_hCom = NULL;
return COMMSERROR;
}
if (radd==0)
{
CloseSerialPort();
return COMMSGOOD;
}
Cheers
Jim

What happens if you use OPEN_EXISTING instead of CREATE_ALWAYS?

In addition to the "For communications resources, the dwCreationDisposition
parameter must be OPEN_EXISTING" problem...

NULL is not an invalid handle value. INVALID_HANDLE_VALUE is an invalid
handle value.

NULL is not INVALID_HANDLE_VALUE, but (I guess) it is still is an invalid handle value. 
That's said, I agree with you: he should return INVALID_HANDLE_VALUE.

If this is possible, I don't think it should be.
To borrow a phrase, "what if you could do this?"
1/ Do you think people who write viruses / trojans / rootkit / bad stuff(tm) would say to themselves "oh, it would be irresponsible of us to use MakeOurAppUnstoppable (), so we'll leave that API only for good people".
2/ You have a bug in your program, and it's in an infinite loop, guzzling memory. How do you close it to put your NewEvenShinierApp.exe?
3/ There is no (3). I'd convinced myself at (1)...

Wonderful. 
Good stuff for 'memorable quotes' on my blog.

I am not able to think of a legitimate purpose why you want to do this. Why should your process run forever? The user must have the freedom to quit any process that they want to and delete any files that they want to.

How about a software that can keep an eye on all the users logged in to your office network at any given time, and of course the users should not be able to terminate this. Trying to achive something like without using access previlages and no service, it looks he has few windows 9x clients also

One good use:
Anti-malware, keep the program running as a diagnostic tool.
Ps.
Ring 0, or ring 3 can't think of it.
IF you look at it from a malware writer's perspective, it would usually involve dll injection, dual processes, or creation of a driver.
Whether the code is revealed or not, malware will ALWAYS be written as will diagnostic software.

But why do you want to do it I want to delete or uninstall your program ?

If you can take the Admin out of that list, then this should be possible by carefully assigning the permissions, for the users you may wish to deny.

A service is also an executable. Anyways if you dont like the idea of service, still you can try remote execute your application as an administrator through network.

Sure, no sweat
First of all, the best approach I can see for this is to use a LayeredWindow approach. This necessitates win2k or higher and just 2 changes to your code.
It also means that 1 of the 2^24 colours available cannot be used, as this is used as the mask colour.
First, goto the line that sets the background for the window class
and change it to (where RGB(255,0,255) represents an arbitrary colour choice)
wndClass.hbrBackground = (HBRUSH) CreateSolidBrush(RGB(255,0,255));
Next, goto the line that updates the window after it's shown
and change it to:
SetLayeredWindowAttributes(hwnd, RGB(255,0,255), 255, LWA_COLORKEY|LWA_ALPHA);
Voila! You should now have a bunch of circles floating on whatever is under them.
Add this code, and you can drag it using the left mouse button.
case WM_LBUTTONDOWN:
SendMessage(hwnd, WM_NCLBUTTONDOWN, HTCAPTION,NULL);
break;
In the above code, I have used 255,0,255 as the mask colour.

Hi..
Thanks for the help.. But i guess i need HOLLOW_BRUSH. To make it look like i draw on desktop screen..
After using your code it doesn't get hang on previous window. But i need to make the background transparent..
I hope you getting my point..
Thanks.
