Hello
Yes. I already tried this. The problem is that it doesn't work. The project doesn't compile. There are erreur.
- error C2146: syntax error : missing ';' before identifier 'dwReserved1'
- error C2501: 'DWORD_PTR' : missing storage-class or type specifiers
- error C2501: 'dwReserved1' : missing storage-class or type specifiers
- error C2146: syntax error : missing ';' before identifier 'dwReserved2'
- error C2501: 'DWORD_PTR' : missing storage-class or type specifiers
- error C2501: 'dwReserved2' : missing storage-class or type specifiers
- fatal error C1189: #error : "The sample framework requires a Unicode build. If you are using Microsoft Visual C++ .NET, under the General tab of the project properties change th
#ifndef UNICODE
#error "The sample framework requires a Unicode build. If you are using Microsoft Visual C++ .NET, under the General tab of the project properties change the Character Set to 'Use Unicode Character Set'."
#endif
May be a library is missing, but I don't know.
thank you

Maybe I'm missing something, but it looks to me like you've just answered your own question. DirectX 9 (according to a quick google search) requires Unicode builds. Either set the project as a Unicode build in Visual Studio like the 'fatal error' is trying to tell you to do, or just #define UNICODE at the top of your project somewhere.

Hi folks,
I've just got stuck on the following issue, easy-looking at the first glance:
I've got a char variable and I need to output its value as a number making use of << intrinsic ostream insertor. But a character appears as the result on the output instead of number, and it seems there is any suitable manipulator in ostream to force the insertor to translate the char value as a number.
In C, I can write:
unsigned char X = 65;
printf("%c\n", X); // the result is character 'A'
printf("%u\n", X); // the result is number 65 - and that is what I need
But, in C++:
unsigned char X = 65;
cout << X << endl; // the result is character 'A'
// ??? How to output number ??? without necessity of casting to int ...
Thanks a lot for any suggestion, Petr.

What about cout << (int)X << endl; ?

Hi all:
Recently I've finished the coding of a tiny function which is to specify the files(Mp3s) order (by which the one appear first can be played first in the Mp3 player, this order depending on the result of DOS command "dir").
I'm not familiar with file system, after a little research, I found that the order in which you copying file to the destination folder(Mp3 Player Destination drive) is the order that the mp3 will played. So I implemented the code according to this principle. I was excited to found I really can control which mp3 should be played first. But after a little testing I found that this principle is not running stable, It will out of order once in a while.
Finally I decided to turn to another alternative which is FDT(File Directory Table). I heard from some guys that FDT can decide the file order either but much at low level.I wish I could write to the FDT of each file such that to achieve the objective. Can anybody provide the principle of writing to FDT or totally different method to affected the file order?
really appreciated ！！！;)

didn't you just posted that ?!!?!
anyway ...
me think you are making your life difficult ...
just use FindFirstFile/FindNextFile in your mp3 folder to load the file into a list and sort it internally in your program.
let the user decide how to play the files.

Does anyone know if you need Unicode strings to store Turkish characters? I thought it wouldn't be necessary because ASCII works with normal European characters (e.g. ñ, é), but I am having some problems with the special Turkish ones (e.g. ğ, ş, ı )
|

ASCII includes only the characters a-z and A-Z, for anything else (like ñ or é) you need either Unicode or one of the 8-bit ISO character sets. You could use ISO 8859-9 character set for Turkish, but then you must include the information about the character set in use somewhere in the data. Unicode is better because it's not ambiguous. See this article: http://www.joelonsoftware.com/articles/Unicode.html[^]

Hello,
I'm looking for suggestions on how to design an text input file. I imagine that each line of the file would look something like this:
Operation argument1 argument2 argument3 etc.
I understand how to do file input if you just want to read one word at a time using the >> operator, but I'm not sure how to "check" what the incoming input is. For example, if a line in the input file started with the operation "CreateNewAccount", how do I (programmatically) check what the string says? If I use std::string for the input the >> operator doesn't seem to like it. If I use char arrays, I can't seem to get two strings to be recognized as equal.
Thanks you for suggestions for how to do this, or perhaps for better ways to go about it. If there is any part I need to clarify let me know.

To be more specific about the problems I was having:
I wanted to try to read the words into string variables so that I could compared them to strings indicating which reaction they correspond to. However, if I try to read the words into std::string variables using something like:
inFile >> tempString;
then I get a compiler error:
error C2679: binary '>>' : no operator defined which takes a right-hand operand of type 'class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >' (or there is no
acceptable conversion)
I also tried reading the words into char arrays so that I could comapare the char arrays to the string corresponding to a particular operation. If I do that, however, then the comparison doesn't seem to work. Ie: If I read the word "Account" into a char array called charTemp, the statement (charTemp == "Account") seems to evaluate to false (even tho my intention would be for it to be true).
I hope that clarifies the problem rather than making it more complicated!
Again, I am open to alternative suggestions.

You are comparing two pointers that point to different things so they are obviously not equal. To compare the contents of char arrays you have to use strcmp().

Thank you - your answer makes sense. I will continue writing the input file using strings.

Hello,
there seems to be a problem with this code:
RECT pos = {0,0,0,0};
dc.DrawText("Hello 1", &pos, DT_CALCRECT);
dc.TextOut(0,20,"Hello 2");
only "Hello 2" will be printed out. Why is that? Shouldn't DrawText work as well?
Many thanks in advance!
|
|
|
|
|
The DT_CALCRECT flag tells DrawText to calculate the size of the rectangle needed to draw the text, DrawText does not do any actual drawing if this flag is used.

Hello,
I have an application using a stream based socket that is set up to look for asynchronous events. When attempting to connect I get a WSAEWOULDBLOCK error which usually happens because the connection cannot complete immediately.
Therefore, I want to use the select() function to wait based on a timer value until the socket is ready for reading. If it is never ready then the function will time out.
Can someone show me an example of how to use the function? I am having some trouble using Winsocks documentation to set it up.
Thanks.
Jerry

When using _malloc_dbg( size, _NORMAL_BLOCK, __FILE__, __LINE__ ), it reports a memory problem if the memory is not freed.
now, if I have a function that wraps malloc ( and _malloc_dbg ), the line reported by _malloc_dbg will be inside that wrapper function; and not from where that wrapper was called.
void* MyMalloc( int size )
{
void* p = NULL;
...
#if _DEBUG
p = _malloc_dbg( size, _NORMAL_BLOCK, __FILE__, __LINE__ );
#else
p = malloc( size );
...
return p;
}
Is there an easier way to have __FILE__ and __LINE__ from the caller without having to create a different wrapper for the debug and release versions ?
Now, I have #define in my code that will either call _malloc_dbg or my own wrapper.
I hope it's clear enough.
Thanks.
Max.

Why not do it the same way MFC does it with new and DEBUG_NEW?
#ifdef _DEBUG
#define MyMalloc(size) MyMallocFunction((size), __LINE__, __FILE__)
#else
#define MyMalloc(size) MyMallocFunction((size), 0, NULL)
#endif
...
void *MyMallocFunction(int size, int line, LPCTSTR file)
{
void* p = NULL;
...
#if _DEBUG
p = _malloc_dbg( size, _NORMAL_BLOCK, file, line );
#else
p = malloc( size );
...
return p;
}
In your client code you just call MyMalloc(100) and it will work just the way you expect.
[edit]the stricked out #else block is not needed[/edit]
