Thanks for the warning. In my registry code, the source I got my code from said that if I tested the 'result' of querying the key at the end of a series of queries, it would fail if any one of them failed, so I ony need to test it the final time. I dont know if thats sound programming, but thats what I read. I feel like I'm walking on eggshells now, since there are zillions of user choices that could trigger errors that I havent accounted for. Also, every time I do a 'new' I havent checked for NULL which I should do in case theres not enough memory and the pointer comes back NULL right?
I'll have to spend one day going through the code and putting in error tests whereever I can forsee they are required. Thanks for the caution. This stuff is nervewracking! Not being transparently predictable.

Is there any way to use GetFileSecurity API in an application that will also be used on a 9x machine? Because when you compile and run on 9x you get errors because the OS does not have that API. If so could someone show me how. Thank you.

You should use LoadLibrary and GetProcAddress.
I'm not sure if it's possible to use delay load in your case - this technique works on per-library basis, and the function in question is located in advapi32.dll.

I really don't know how to interpret this:
error C2598: linkage specification must be at global scope, when I click on it it takes me to this function, I will bold the text where the arrow points to. I'm lost......again.
void Create_Report(Diver_Info theDivers[])
{
ofstream OutputFile;
OutputFile.open(ReportFile, ios::out);
OutputFile << setiosflags(ios::fixed|ios::showpoint) << setprecision(2);
OutputFile << setiosflags(ios::left) << setw(6) << "Place" << setw(26) << "Name"
<< setw(8) << "Score" << endl << endl;
for(int i = 0; i < Best_Divers; i++)
{
OutputFile << setw(6) << (i + 1) << setw(26) << theDivers[i].Diver_Name
<< setw(8) << theDivers[i].Total_Score << endl;
}
OutputFile.close();
}
My header file that I am including does #include <fstream.h>. Any ideas?

Compiler Error C2598
linkage specification must be at global scope
The linkage specifier was declared at local scope.
The following is an example of this error:
void func()
{
extern "C" int func2(); // error, linkage declared in
. // block at local scope
.
.
}
extern "C" int func( int i ); // OK

Right, well I read that at MSDN too, however it doesn't mean anything to me. Could you explain. I am just trying to create a file stream to write an output file. What else do I need?

if u copy paste ur function into a console application does it work? if it doesnt, u declared a function in a scope of another

Hmmm... I'm pretty sure I understand what you are saying, however after looking through this I don't see where I have done that. Maybe I need to go strech my legs.

Make sure you are not mixing IO.
try to use <fstream>
|
|
|
|

if i copy your code into an empty app and add the appropriate headers (and a fake DriverInfo struct), it compiles fine.
#include "stdafx.h"
#include <iomanip.h>
#include <fstream.h>
struct Diver_Info
{
char Diver_Name[26];
int Total_Score;
};
void Create_Report(Diver_Info theDivers[])
{
int Best_Divers = 0;
ofstream OutputFile;
OutputFile.open("c:\\temp\\ofs.txt", ios::out);
OutputFile << setiosflags(ios::fixed|ios::showpoint) << setprecision(2);
OutputFile << setiosflags(ios::left) << setw(6) << "Place" << setw(26) << "Name" << setw(8) << "Score" << endl << endl;
for(int i = 0; i < Best_Divers; i++)
{
OutputFile << setw(6) << (i + 1) << setw(26) << theDivers[i].Diver_Name << setw(8) << theDivers[i].Total_Score << endl;
}
OutputFile.close();
}
int main(int argc, char* argv[])
{
Diver_Info d[2];
Create_Report(d);
printf("Hello World!\n");
return 0;
}

That does seem to surprise me, nothing seems to surprise me anymore 
I am not sure what is going on, it appears to be correct, but the compiler just spits it back at me. I am sure I am doing something wrong here somewhere.

If you leave off a ; on a class declaration you can end up with very confusing error messages
class MyClass
{
} <--- oops!
And there's very little that will pin-point the actual errors. In cases like these you just have to try changing/removing things until you can narrow down the actual error.

Are you including the right fstream header somewhere else ? fstream.h is not standard, you should include fstream instead. The same goes for all other iostream headers such as iosfwd and so on.

Having worked in Boreland Builder for GUI the last 4 years, was forced to use VS and MFC to do a rather complicated GUI. I simply can not believe it is as painful as it seems.
The some of the GUI libs on here are very nice, but on the whole the work has to be a factor more.
Are there any benefits to using VS and MFC over an actual RAD enviroment?

MFC looks good on your resume.

Hi,
Yeah, it definitely looks good on your resume and is a must-have. However, having said that I am not a big fan of MFC myself. It really bloats up the software and makes it sluggish. However, companies use it and you are left with no choice. In my personal projects, I make wrapper classes around the WIN API.
Relisoftis a good resource if you want to learn about programming for windows without the use of MFC. Even if you use MFC, it is a site worth looking at. I am not saying, do not use MFC at all. But it sure is a good learning experience, if you know your way around WIN32 API.
My 2 cents

VS and MFC aren't exactly the best RAD tools available, but I find they have more power and flexibility than Borlands offerings. It depends on what you are trying to develop. MFC is great for building large applications, but you do need to know how and why things work in it.
I love MFC, but it is starting to show its age but for nearly 10 years it has allowed me to develop lots of Windows applications quickly (if not always easily)

Hello, where do I get my hour/minute from the computer?
CString mydate;
mydate.Format("%d:%d", xxx );

Assuming you can use native Win32, see:

Not sure how MFC does things.

Check CTime::Format and COleDateTime::Format.

Using MFC, you could use the CTime class.

Hello and thanks in advance for your help.
I've got an app that's been released into production for a couple years now. Recently I've had reports of an IPF occurring at 01F:004013AB. I have not been able to reproduce this error in my testing environment.
I have tried to set a breakpoint at this memory address, but the IDE shows an error. I've noticed a few things - one is that the memory address maps to different code locations depending on wether I'm running a beta or release version in the IDE. So I've been trying to break at the memory location when in release configuration and checking the disassembly - with no luck. The other thing I've noticed is that this is a very early memory location, seeing that windows loads apps at 00400000.
Does anyone have any insight into this? I'm wondering a few things: is that memory address (004013ab) comparible across OS'es? Is it comparible across machines? Is there a way to figure out what is causing the error without debugging on a machine that is causing the error?
