May be you havent correctly set the parent window while creating the other dialogs. Also check the whether the dialog has WS_POPUP style.

Unicode 5.1 ( Basic Multilingual Plane ) - Language Identification related problem

Hi There.

I am creating an application that will take a document as an input and will find Total Number of languages used to compose the same.

I am refering below web link to do the same...

http://en.wikipedia.org/wiki/Basic_Multilingual_Plane[^]

Let me also share some code snippet with you guys...

FILE *fp;
long unicode;
long c;

fp = fopen(argv[1], "r");
if(!fp)
{
	printf("File open failed\n");
	return 0;
}

printf("Input Unicode file: %s\n", argv[1]);
c = fgetc(fp);
c = fgetc(fp);

while( (unicode = fgetc(fp)) != EOF)
{
	long unicode1 = fgetc(fp);
	unicode = (unicode1 << 8) | unicode;
         //(0000–FFFF): Basic Multilingual Plane (BMP).
	if (unicode >= 0x0000 /*0*/ && unicode <= 0x07FF/*2047*/) 
	{
		if (unicode >= 0x0000 && unicode <= 0x007F) //Basic Latin (0000–007F) 
		{ 
			unicode_set[Basic_Latin] = 1; 
		}
                .... 
                .... 
                .... 
        }
}
fclose(fp);

I got this code from one of my previous projects. But I am not able to understand why are we doing
unicode = (unicode1 << 8) | unicode;

Also, this method is not able to correctly identify all the chars.

Just FYI, I am using VS.NET 2008 with "Charset settings" as "Use Unicode Character Set"

Please suggest, if you have any other way to find out, like what all languages we have used to compose a document?

Thanks
PanB

That converts the two characters unicode and unicode1 into a single 16-bit wide character. It assumes that the wide characters have been stored in a little-endian fashion.

Possibly because not al unicode characters fit into 16 bits?

Can you please suggest some solution for the second problem mentioned above? i.e., Possibly because not al unicode characters fit into 16 bits?

I'd suggest that you use some library (like, say libiconv[^] to read the file and do the conversion from whatever character encoding is used for the file to a full Unicode enconding (e.g. UTF-32). Then process each of those 32-bit characters the way you are in your original code.

HI,
im using CopyFile function as below...

::CopyFile(_T("F:\\test.ini"),_T("E:\\test.ini"),FALSE);
ie im copying ini file from a DVD which in F Drive to E drive...

BUt the issue is the copied file is in Readonly mode..how can i change to Write mode using code...

normally if i copy file from one localdrive to other it is not in Readonly mode...but if i copy from CDDrive then the file becomes Readonly..?

The documentation for CopyFile[^] states that:

File attributes for the existing file are copied to the new file. For example, if an existing file has the FILE_ATTRIBUTE_READONLY file attribute, a copy created through a call to CopyFile will also have the FILE_ATTRIBUTE_READONLY file attribute. For more information, see Retrieving and Changing File Attributes.

Given that all all files on a CD drive are read-only, your problem is not surprising.

The solution is to use the SetFileAttributes[^] function on the destination file after the copying is complete to make the file writeable.

Here's a previous answer given to this sort of question (i.e. reading a PST file)[^]. Also, libPST[^] might be useful - it's not documented as building on Windows, but I suspect it wouldn't be difficult.

Reading strings containing escape sequence.

Hi,

In my application, I need to read an unicode string _T("AT+COPS=?\r") from an xml file.
The problem I am facing is that when I read an string from the xml file, it is treating the elements "\r" in "AT+COPS=?\r" as 2 different characters rather than a single carriage return value.

How do I get around this problem.

Re: Reading strings containing escape sequence.

Cedric Moonen1-Jun-09 20:26

That's how it is supposed to work. Escape sequences are only used this way in string litterals (e.g., when you write the string yourself in the code). If you read that from a file, "\r" are two characters and they are treated as two independant characters. What you have to understand about escape sequences (like "\r") is that they are replaced by your compiler by a single character.
If you really want to do something like you that, you will need to parse the string yourself and replace the sequence yourself.

I am working on MDI application which has some lengthy operation on
View and also on some dialog boxes, I want to display busy cursor hours glass I implemented as below it is working during the length operation on the View, but when while there was a lengthy operation on the dialog, mouse pointer is not changed on the dialog, but if I move the mouse on the MainFram then the mouse pointer is changed, I want the mouse pointer to be changed on the Dialog also, please advice

view.cpp

void CMyView::PerformLengthyOperation()
      {
            m_ChangeCursor = TRUE; 
            AfxGetApp()->DoWaitCursor(1)

            //...

            AfxGetApp()->DoWaitCursor(-1)
            m_ChangeCursor = FALSE; 

      }
				

      BOOL CMyView::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
      {
            if (m_ChangeCursor)
              {
                  RestoreWaitCursor();
                  return TRUE;
              }

            return CView::OnSetCursor(pWnd, nHitTest, message);
      }

Then why don't you use this

Until the operation that you are doing is over?

But I want the same to work in my application also, Please help

int i=0;

  SetCursor(LoadCursor(NULL, IDC_WAIT));

You cannot expect the cursor to change while you have yourself blocked the message processing loop. For the cursor to change you must return and then let the message processing loop handle the cursor change message.
As far as I understand you need a separate thread for doing the time taking processing or do it in OnIdle
Hope this helps
