Because inherently, the "..." is a literal, and is placed in a const segment. This *should* be a safe thing to do, and the segment then can be read-only. This allows the compiler/optimiser to use string pooling (multiple occurrences of the same literal can be folded into one). The address (char*) is the variable part, and is in the r/w segment.
The [] version simply declares and initialises some of the r/w segment, and is different.

The string is in code segment.

DOS version of Turbo C++? The code segment is read-only on Windows.

Howdy,
Does anyone know of a macro or whatever which lets you display line numbers in the VC6 Editor? I am having no luck so far...
Cheers

Try this dude..... but it's for C under Linux...might work here too.
#define TRACE printf ("%filename, %linenumber\n", _ _FILE_ _,_ _LINE_ _)
be careful with the "_"
and call TRACE anywhere you want. IE: TRACE; that's all
Good luck to ya.

Hi,
I'd be oblidged if someone can give me the code (using VC++) to accessing a particular port at a specified IP address.
The code should detect for failure(-1) or success.
Many Thanks,
John

Looking through a log file from Dr Watson (drwtsn32.exe) i found the following line
'------------ Stack Trace ---------*
FramePtr ReturnAd Param#1 Param#2 Param#3 Param#4 Funktionsnavn
01712610 00000665 6C3A1C58 01711320 00000001 6C3A1C58 !DLdbAPI::`default constructor closure'
Now I am wondering what 'default constructor closure' means ... can anyone help (the program that creates the dump/crash is in visual c++
Something clever

I *guess* this may be the default constructor generated by C++ compiler. Do you have the source for DLdbAPI class?

Yes I do have the source, but it doesn't really give any hints as to what this could mean. But I suspect that you're probably right, it probably has something to do with the default ctor.

Is there a difference between Visual C++ and C++
|
|
|
|

Question is Silly but Good
VC++ is Microsoft specific...

C++ is a programming language, Visual C++ is Microsoft's product for programming in the C++ language.

This is the nicest (shortest and accurate) explanation

Can C# use the unmanaged classes I created with VC++ 6.0 before, which use many pointers ?
|
|
|
|
|
No. C# and C++ are totally different languages.

Yes. Just build a DLL around it.
Then from C# you call the exported DLL functions thanks to the [DllImport("mydell.dll")] attribute.
The other way is also possible. Documented in MSDN.

Hi,
Tell me what means "CancelIo"?
Thnx
Extreme programming. Do the No.1
|
|
|
|

I guess you're after API function CancelIo which "cancels all pending input and output (I/O) operations that were issued by the calling thread for the specified file handle. The function does not cancel I/O operations issued for the file handle by other threads". MSDN has the details.

I am working on 3D Studio Max R4 to create a plugin using visual c++6.0 However, when I tried to add a win32 API using a sample cpp file, I get this error: c2065 undeclared identifier
I have defined the API in resource.h, .rc file format and the .cpp format. However, I still get that error. In addition, I have updated my SDK in Aug 2002. Can someone solve this prob? I will be grateful for that. Thanxxx.

So what's the name of identifier causing C2065?
