Maybe the new .h file is windows.h and it defines DWORD BYTE already..?
But im sure if you go through your code you will see your missing the smallist of things.. for e.g. a } to end a function thats a common mistake for EOF or not ending the quotation "ajsaf \n);
just comb through

Ok this might sound weird but i can't seem to pipe the results of dir etc
all i want to do is make a win32 app that is like cmd.exe, i can work out the rest.. so how do i pipe dir etc into a buffer.. I just cant work it out and its making me crazy..
ReadConsole() only grabs what sum1 types into a console doesnt grab the output of the program.. Cheers for your help in advance

My instructor asked us to write a class definition and put it in
the header file. Then he gave us three files: "Speak.c", "music.cpp"
and "speak.dll". However, he did not mention how does dll work, and
where should it go?
In the .Net solution explorer, there are References, Source files,
header files and Resource files. So I put "Speak.c" and "music.cpp"
in the source files, and I created a header file for the class definition.
However, I don't know where should the dll go?
What is the Resource file and References?
P.S. I'm writing a console based program, not windows based.

You could put it in your
- current directory
- windows directory
- windows system directory

I put the speak.dll into the current directory, then tried to add
the file into my current project (through solution explorer), it
gave me an error. I was trying to add it into the reference.
Did I do any thing wrong?

I am talking about Visual C++ 6.0.
When I need to call a DLL. I basically just include the header file in my source code like this
#include "myHeader.h" //which is the header file for my DLL.
and then copy the DLL into my project which if my project is an executable, I will just put it in my output directory.
Eg. C:\My project\Debug\a.exe
copy to C:\My project\Debug\myDLL.dll
The "add reference" is not in the Visual C++.NET as I had checked it just now. It is only available in C#. Are you sure you are building a right project?
BTW, even the "add reference" is available. It is a reference to .NET assemblies. Don't get mix up the assemblies with old windows DLLs.

just copy it to any directory in the PATH environment variable
Don't try it, just do it! 
|
|
|
|
|
How do I know which one is the PATH environment variable?
There must be a way to know it. And besides, is it enough
just to put the dll into the directory and do nothing? Jut
put there? Don't I need to add it to my project?
Thanks

Hello, everyone!
I think we can only use "#define" statement to define an int variable, for example,
----------
#define FOO 100
----------
I want to know whether I can use "#define" to define a short int, or unsigned numerical type? Or any numerical type of C/C++?
Thanks in advance,
George

In addition to Michael's post, if you are exclusively using C++, declaring variables as consts is the preferred method to defining constants. This is much more typesafe than using #define. Scott Meyers has more on why you would prefer this in one of his "Effective C++" books.
eg:
const short myNum = 100;
const double myOtherNum = 1.234;
etc etc
If you are using C or a mixture of C/C++ (ie , you are compiling one or more modules as C code), then this method does not work, so YMMV.

I am sorry for having to ask such a stupid question but how do I check if an edit control is empty? I have tried comparing the contents of the window to NULL but that does not work. I have also checked to see if the CEdit class has an IsEmpty() type function and I can't fine one. Does anyone know how to do this?
Thank you all for your patience.

I have four octets of an ip stored as follows.
byte octet1,octet2,octet3,octet4
IPAddressCtrl.GetAddress(octet1,octet2,octet3,octet4);
What I need to do is get those four bytes into a DWORD in the propor byte order so I can store that DWORD in an SOCKADDR_IN structure like this
SOCKADDR_IN saDest;
saDest.sin_addr.s_addr = /*Somehow stuff octet1,2,3,4 in*/
Does anyone know how this can be done?
Thank you

Look at the MAKELONG macro.
|
|
|
|
|
...and if you are messing with network parameters don't forget that it uses network byte order (big endian). Use htonl() and ntohl() to convert between network and host byte order.

Hello,
Heres the situation:
I have a class MatrixN.
I also have a class VectorN.
Now, in MatrixN, some of the functions take a VectorN object as a parameter. In VectorN, some of the functions take a MatrixN object as a parameter.
When I try to include "VectorN.h" in MatrixN and "MatrixN.h" in VectorN.h I get an error of infinite recursion in include nesting. But if I dont include those files I get errors like:
(in VectorN.h) : syntax error : identifier 'MatrixN'
(in MatrixN.h) : syntax error : identifier 'VectorN'
Does anyone know what I can do to resolve this problem?
Thanx for the help,
-Flack

Use forward declarations, i.e. class MatrixN; in VectorN.h and vice versa.
Note that this requires that you use pointers or references in the interfaces.

Is there anyway of creating win32 threads and have them point to a class method. Such as:
#include "GpsControl.h"
#define WINAPI __stdcall
GpsControl::GpsControl()
{thread_handle = CreateThread(NULL,0,&GpsControl::GpsProc,NULL,CREATE_SUSPENDED,&threadID);}
unsigned long WINAPI GpsControl::GpsProc(void *)
{return (unsigned long) 2;}
I keep getting this error:
C:\kbrown\quat\GpsTest\GpsControl.cpp(8) : error C2664: 'CreateThread' : cannot convert parameter 3 from 'unsigned long (__stdcall GpsControl::*)(void *)' to 'unsigned long (__stdcall *)(void *)'
I really need the thread to use this function. Any Help would be MUCH appreciated.
