You need to set them for both Release & debug's property pages. Did you do that for both?

I just set them in project->settings

delete _MBCS and add _UNICODE,UNICODE

I am wondering if I use TCHAR cause this problem

because for ansi build TCHAR = char

How I change the setting for both of them

This is the first time using UNICODE

Poke tongue | ;-P

Thank you VuNic

If you are using TCHAR then there shouldn't be a problem. But it also counts how are you using it.

Yes, this is fine. You need to repeat the same after you choose "Release" version. Because the settings you give in the project properties in debug mode applies only to debug versions. ReDo the same after you choose "Release". This is what I asked you to check.

I will check that

Now I am not at my computer

About TCHAR I use in a struct

struct WORD_DATA
{
    TCHAR word[10];
    unsigned int hashVal;
    unsigned int localAddr;
};

This struct is for READ & WRITE a UNICODE word file

It saves the data about word so I can use them to segmentation

So is that TCHAR using correct??

and what suggestion do you have forme in UNICODE programming?

There's a nice article from Chris itself :Click[^]Search for "Reading and Writing ASCII text files" in the article. Your problem would be addressed.

Also you may check this one:Clicky[^]

Release and Debug mode, I both defined _UNICODE, UNICODE

I changed all TCHAR to wchar_t

But the problem still exists

Are you using cout<< to display you string? Show me the link that creates the problem.

No I use cout to display a int value of the string

The word lib save the string like this

struct WORD_DATA
{
	unsigned int hash;
	TCHAR word[10];
	unsigned int address;
	unsigned int localAddr;
};

I use fwrite to write a WORD_DATA and fread to read from the file

First I segment string (such as "you") form source file and get the hash value of string then I go to hash table by index(unsiged int hash(such as 1020)) to find out if it in the table (if there is more than one word that having the same hash value I use wcscmp (wcscmp(WORD_DATA.word, "you")) to find the correct one)

But Release mode it all failed (can't be found) and Debug it runs correctly

At last if the word exists I push back the localAddr value to vector<int> then display all the results But Release mode because all failed to find no results displayed

Confused | :confused:

If it still not clear I can post my program to you

Thank you so much
it's so kind of you

Tell me few things,

1. Are you writting the files in binary, or text mode? If text more, Are you able to read "see" the contents with your eyes? Are they written properly?

york528 wrote:

2. Do you mean, the text file is written properly but it does not read the string properly? Also when you read the string "You" from the line, are you able to print the word on screen?

3. How do you construct the hash table? As and when you read the file you create the file? or it's loaded from somewhere?

--*---*
4. I prefer using fstreams. Why do you use fwrite? any specific reason?

5. Send the solution to dejavunic@gmail.com

6. I'll fix it for you tomorrow. But I'm not sure if I'll be free. So keep trying. When I get time, I'll do it for you.

Hi VuNic

I found the mistake but I don't know why??

This is my hash function

int Hash::HashValUnicode(const TCHAR* src, const int nArrayLen)
{
	register unsigned int h;

	while (*src)
	{
		h = (h<<5) + h + *src++;
	}

	return h % nArrayLen;
}

In Debug and Release Mode

It gives diffirent hash values of the same UNICODE string

Such as "you" Debug it give 123 but Release 542(Just a example)

How dose it happened ???

Bad hash function???

Re: UNICODE problem??

8-Mar-09 20:39

OK

It works

Just because

register unsigned int h;

I should initail h;

register unsigned int h = 0;

like this both debug and release give the same hash value

such a little thing drive me crazy

now it's ok

thank you so much

and can we make a friend?

There's a lot of difference between Release & Debug modes.

In debug mode variable gets automatically initialized. So you will not get an undefined behavior. But it's not the case with Release. And there's a lot of other differences between them. If you go through the below article, you'll get an idea.
