Hmmm... does this mean the you display UI stuff from two threads? I'm no expert on multithreading, but according to Joseph Newcomer (http://www.flounder.com/workerthreads.htm[^] (who seems to be an expert) you should never ever touch the UI from a worker thread. Instead, you should post a message from the worker thread to the main thread and have the main (UI) thread display the dialog.
If you for some reason don't want to change your design you should at least protect the access to the bool variable with a mutex (see http://www.flounder.com/semaphores.htm[^])

Actually, I guess you could use the mutex itself in place of the boolean.

I guess you mean SetCapture.
Does it work for you? It does not for me...

Hi all
Please can anyone help me,
How to convert one datatype to other. int to char*
in vc++ many datatypes are there like _variant_t , _bstr_t
what is the actual use of it.
thanks
|
|
|
|
|
if you use CString you can use its .Format() fc.
If not use the right fc in the sprintf family.
as to the variant, bstr type, obviousely it is not too early for you to know -- if you are into com stuff, you will know.
|
|
|
|
|
use _itot
Cheers
Steen.

You can use this sample:
#include <stdlib.h>
#include <stdio.h>
void main( void )
{
char buffer[20];
int i = 3445;
long l = -344115L;
unsigned long ul = 1234567890UL;
_itoa( i, buffer, 10 );
printf( "String of integer %d (radix 10): %s\n", i, buffer );
_itoa( i, buffer, 16 );
printf( "String of integer %d (radix 16): 0x%s\n", i, buffer );
_itoa( i, buffer, 2 );
printf( "String of integer %d (radix 2): %s\n", i, buffer );
_ltoa( l, buffer, 16 );
printf( "String of long int %ld (radix 16): 0x%s\n", l,
buffer );
_ultoa( ul, buffer, 16 );
printf( "String of unsigned long %lu (radix 16): 0x%s\n", ul,
buffer );
}
Output
String of integer 3445 (radix 10): 3445
String of integer 3445 (radix 16): 0xd75
String of integer 3445 (radix 2): 110101110101
String of long int -344115 (radix 16): 0xfffabfcd
String of unsigned long 1234567890 (radix 16): 0x499602d2

Do a search on MSDN for _itoa. You may come across: atoi, atof, atol, _itoa, _itow, ltoa, ltow, strod, strol, stroul, _ultoa, _wtoi, _wtol, _ultow. Lots of conversion functions for you!

How to write data to blank CD using VC
thanx

KK

Hello.
If you are using Windows XP, then there are two built-in CD-burning APIs.
The simplest one is ICDBurn.
If you need more control, use IMAPI (also in XP).
Else, I suggest you buy a Nero license and use the Nero API/SDK (which is free to download and use).
It might be a bit complex, but there are a lot of samples out there, just Google for them.
I use the Nero API/SDK for burning data-CD's and DVD's for a customers software and it works very, very well.

You can use Excel automation also. Make a search on google (or this website)
|
|
|
|
|
You can find info on many file formats here inclusing Excel.

use Excel automation
CApplication app;
CRange range;
CWorkbook book;
CWorkbooks books;
CWorksheet sheet;
CWorksheets sheets;
VARIANT ret;
COleVariant covTrue((short)TRUE),covFalse((short)FALSE),covOptional((long)DISP_E_PARAMNOTFOUND,VT_ERROR);
try
{
CoInitialize(NULL);
if(!app.CreateDispatch("Excel.Application"))
{
AfxMessageBox("Cannot start Excel");
return;
}
books = app.get_Workbooks();
book = books.Open(fname,covOptional,covOptional,covOptional,covOptional
,covOptional,covOptional,covOptional,covOptional
,covOptional,covOptional,covOptional,covOptional
,covOptional,covOptional); // different for different ver of Excel
// check msdn website
sheets = book.get_Worksheets();
sheet = sheets.get_Item(COleVariant((short)1));
sprintf(cell,"%c%d",alpha[k],j); // eg A1, A2, etc
range = sheet.get_Range(COleVariant(cell),COleVariant(cell));
ret = range.get_Value2();
CString t = ret.bstrVal; // t will hold the value of the cell
books.Close();
app.Quit(); // close excel application remember to close application
}
catch(COleException *e)
{
char buf[1024];
sprintf(buf, "COleException %081x.", (long)e->m_sc);
}
catch(COleDispatchException *e)
{
char buf[1024];
sprintf(buf, "COleDispatchException %081x.", (long)e->m_wCode);
}
catch(...)
{
char buf[1024];
sprintf(buf, "General Exception");
}
hope tis helps

I use Visual Studio 6. Is it possible to select a rectangular area that does not start from column zero, and copy that text?
|
|
|
|
|
Are you refering to Visual studio editor???
|
|
|
|
|
i think he means into the source editor ; the behavior is the one we could find into UltraEdit under the feature called "Column mode selection".
but i don't know how to do this in VS6...
