Sure the header file hasn't been edited somehow? Both my afx.h and afx.inl (from VS2008, not VS2005, but I can't see them changing) have CFile *CArchive::GetFile(void) const

I used VS to create a new project and compiled the release version. I also got these error messages. I am trying to re-install VS.
Thanks,

Hi,
I am having a problem declaring and passing a multidimensional array of floats as an argument to a function. Can someone help me with this problem? My code is enclosed.
Any help appreciated.
float* pData = new float[nNumRows,2];
for( int i = 0; i < nNumRows; i++ )
{
pData[i][0] = ((CSodSpecData*)pOdbSpecData)->m_cvData[i].Real();
pData[i][1] = ((CSodSpecData*)pOdbSpecData)->m_cvData[i].Imag();
}
lErrorCode = pService->serviceNotifyDataEventSet( pData[0], strSensorName );
CDFstatus CABCDEntryPointService::serviceNotifyDataEventSet(float* dataSet, const CString& varName)

Without knowing what that method requires at the address sent as the first parameter all I can offer is this will compile. No way to know if is correct.
pService->serviceNotifyDataEventSet( pData, strSensorName );
or
pService->serviceNotifyDataEventSet( &pData[0], strSensorName );

Should this be:
float pData = new float[nNumRows][2];

Hi
I want to add wide char support to my software. If I do this, I will need to change a lot of code. If the software is changed to wide char, does this wide char software can handle ANSI char as it used to be?
Is there any advice or good experience?
Thanks,

Not at all true.
"Hello World" is an ANSI string, even in a application build with UNICODE libraries.
L"Hello World" is the UNICODE string in either environment.
_T("Hello World") varies.
Even the underlying API has both Wide and Ansi versions. Sometimes the strings in these are converted. Other times they are not.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

I wouldn't expect anyone reasonable to define strings like this, unless for a debate. My point was that he should not be including ANSI stuff into an Unicode application (why not Unicode?), as that might bring down the performance.
I assume the usage of generic text mapping routines and I could have specified it clearly. Does my comment make sense if string literals enclosed within the TEXT macro?

Also, if you write an application in ANSI, Windows will still have to convert everything to Unicode internally to work with it. So, theoretically your application must be faster if it is built for Unicode.

It wasn't clear enough that I told "Windows" and not APIs? An API may have both versions, but when it has to pass on a string to Windows, it must be converted to Unicode. Even if a function returns an ANSI string, again, Windows actually returns a Unicode string and there happens another conversion which is not visible to the user calling the API and essentially the performance goes down.

I have a COM ATL based exe server that supposed to to be a single instance. It generally runs as a windows service. However when I debug it ti doesn't act the way I'd expect. I start it in the debugger. I then have a php script that gets executed by the apache webserver. This php script creates a COM object that is vended out by my COM server. However instead of using the instance of the server that I have running, a new instance is started up, in what appears to be the System account. Is this some weird permissions rule, that because the script is being executed by a process running as a service, that COM creates a second exe server instance in the same security context? Is there way around this? Or is there something blindingly obvious that I'm missing?

Yes, out of process COM communication is basically permitted only if both sides run in the same security level (if I get it correctly )
Anyway, here is a workaround[^] according to the COM people at MS.

Thanks, that's a great link. It does have the unfortunate side effect of making me want to jab a fork in my eye. What a frigging mess

Probably, but you'll need to post your code snippets here (i.e., only relevant code), rather than require someone to download your whole project from some other site. Some of us have soap operas to watch and Bonbons to eat so time is important.

Here is the code snippet i wrote when the custom button clicked
void CHashiDlg::On_AddSubtract_action()
{
UpdateData( );
double numA ,numB ,result ;
numA = atof(m_num1) ;// edit control number1
numB = atof(m_num2) ;// edit control number2
if(m_two_actions_botn.OnRight()) { // check whether the mouse clicked right half
m_results = numA + numB ;
UpdateData(FALSE );
}
else {
m_results = numA - numB ;
UpdateData(FALSE );
}
UpdateData(FALSE );
}
it performs no action loll

The first thing I'd do is get rid of those unnecessary UpdateData() calls. They are a never-ending source of problems simply because most folks do not know how to use them.
You should then have something akin to:
void CHashiDlg::On_AddSubtract_action()
{
CString strNumA;
strNumB,
strResult;
m_num1.GetWindowText(strNumA);
m_num2.GetWindowText(strNumB);
double numA = atof(strNumA),
numB = atof(strNumB);
if (m_two_actions_botn.OnRight())
strResult.Format("%f", numA + numB);
else
strResult.Format("%f", numA - numB);
m_results.SetWindowText(strResult);
}
