hi Mike
Adding CS_DROPSHADOW is good idea .. But i want to chage the color of shadow
i want to give color shadows . Thats my problem.
Like this
The First color will be Color::Red
The Second wll be Color::Transparent
and i would like to paint it with a LinerGradientBrush.
What you think , Mike ?
If u can Dream... U can do it

I am trying to write a registry value (using RegSetValueEx) of 2182 bytes for a particlular value name of RG_SZ type. But VC++ 6.0 is allowing me to write value of only 2007 bytes. If the size is greater than 2007 bytes then my application crashes with Access Violation.
HKEY hCLSID = HKEY_CURRENT_USER;
KEY phk;
LPCTSTR SKey = "SOFTWARE\\Rajni";
DWORD lpdw=NULL
if(RegCreateKeyEx(hCLSID,SKey,0,NULL,REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS ,NULL,&phk,&lpdw) == ERROR_SUCCESS)
cout<<"Key created\n";
else
cout<<"Key Creation Failed\n";
TCHAR data[8192];
const char * lpValueN = "name";
DWORD dwBufLen = 8192;
if(RegSetValueEx(phk,lpValueN,0,REG_SZ,(unsigned char *)strValue,dwBufLen) == ERROR_SUCCESS)
cout<<"\nSet Value Successful\n";
else
cout<<"\nSet Value Failed\n";
here strvalue is of 2182 character long..
Plz help !!!!!!!!!!
thanks and regsrds,

I would start with correcting the call to RegSetValueEx(...) - the last parameter is the (byte) size of the data to be saved, not the size of the buffer used to store that data. When writing NUL-terminated strings, make sure the data length specified includes that terminating NUL.
See if that helps.

I tested with length data but I think it's not problem
and I use LPTSTR for strValue but it doesnt work
|

I believe the problem is with either the data or the specified length of it. The following example works correctly writing 8K or raw data and as a NUL-terminiated string (8K + 1 in that case):
BYTE btaData[ 8192 + 1 ];
HKEY hKey = NULL;
::srand( time( NULL ) );
for( DWORD dwChar = 0; dwChar < 8192; dwChar++ )
{
do
{
btaData[ dwChar ] = ( ( rand() % 57 ) + 65 );
}
while( !::isalpha( btaData[ dwChar ] ) );
}
btaData[ 8192 ] = '0';
::RegCreateKeyExA( HKEY_CURRENT_USER, "Test", 0,
NULL, REG_OPTION_NON_VOLATILE,
( STANDARD_RIGHTS_REQUIRED | KEY_SET_VALUE |
KEY_CREATE_SUB_KEY ), NULL, &hKey, NULL );
if( hKey )
{
::RegSetValueExA( hKey, "TestValByte", 0, REG_BINARY, btaData, 8192 );
::RegSetValueExA( hKey, "TestValSZ", 0, REG_SZ, btaData, 8193 );
::RegCloseKey( hKey );
}

I think I find answer can you test this code please.

Rajni Kant,
I find your answer you can use 2 string and then use your function
or like this
TCHAR data[8192];
const char * lpValueN = "name";
DWORD dwBufLen = 8192;
const char *strValue;
strValue=(const char*)LocalAlloc(LPTR,2065);
strcat((char*)strValue,"");if example is 1032
dwBufLen =lstrlen(strValue);
RegSetValueEx(phk,lpValueN,0,REG_SZ,(unsigned char *)strValue,dwBufLen);
strcat((char*)strValue,"");//here 1032
dwBufLen =lstrlen(strValue);
RegSetValueEx(phk,lpValueN,0,REG_SZ,(unsigned char *)strValue,dwBufLen);
you get your answer I test with this way and I can save my value

can anyone have a guess of a file if it is some floating numbers or double or long double?
82 46 00 84 A1 FE 2B AF | 9D FA 0D 1D B3 A5 28 1A
96 B6 AC B8 B0 A5 8F 88 | BC A5 76 E1 FF C9 A1 8E
84 2D 4E D1 C8 BF 63 A5 | 75 C2 9F 6F ED 98 9B EF
C0 71 70 95 E3 C3 AC 21 | 0F D9 C7 A5 5C F3 FE 9F

A4 6F 65 3D 57 36 80 AF | D1 26 5F BD 62 BF 21 58
....
a couple from here are converted well as floating numbers thru float *pnt, but others does not seem to work

unless you have a format to read the file, it can be anything and everything.

It's just plain hexa values. It is impossible to say if that comes from an integer, a float, a double, a string or a blue cow (that to say it can be anything). What are those | symbols there ?
If one 'number' is 8 hexa symbols (2 chars), then the values are on 8 bytes which means that they are double or long double (they have the same number of bytes)
|
|
|
|
|
| is just to visually separate 8byte long sequences (old good Norton Commander has such a viewing thing)
it is not a string bits by sure as no of the printable characters at all in the file
it is a file with some data 100% I need to crack for what the numbers are

You won't be able to 'crack' the file if you don't know it's format. It's simply impossible to know what's contained in a binary file.
Maybe if it is a known file extension, you can find the file format on the web.

I think you didn't read my post correctly  . I was speaking about a 'long double' which has 8 bytes (like a double).
|
|
|
|
|
ahhh, sorry... 
for the info, it could also have been a long long
so, the conclusion : no file schema, no crack :->

this is the file with data points for sure.
I wonder if it might be just simple floating points 4 bytes long stored each after other or double or so. That must not be long numbers since the only presumpton about it is the numbers should be in range like -5.0...5.0, not much more than it

Do you know anything about the file?
Where did it came from?
Who (or what program) wrote it?
What's the file name?
|
|
|
|
|
its from some holter monitor and it looks without any headers inside since all the data in it is in no readable chars sequencies, just similar to array of floating or double points
this is the file with data points for sure.

if it was integers or shorts than it must be some sequencies of similar numbers not much different from each other, which is not likely from the hex numbers

Hello.
I came to think about this on my way home from work yesterday.
If it's a measure log, then there ought be a time stamp attached to every measure (series).
If you can find those time stamps, then you can easily find the data between the time stamps.
Maybe it's one way to go?

no hardly there will be any time stamp since it must be plain data from ADC on certain sampling rate and they should follow each other.
it is impractical to introduce time stamp before every point since the file size will be enourmous
it is usualy something only data points, I've tested it with float * and double * and it douesnot worked with every possible step
may be it is in 16bit or 12bit format numbers? will check it

what the file? It sounds like WTF , sorry for the bad joke

If you have an idea of the values which are represented, you could do a bit of trial-and-error.
But the problem is that it could be a single set of values, with time implied (first sample is a float - position - at T0+t, second is position at T0 + 2t, etc)
Or it could be pairs of values (float distance with integer time)
Or it could be triples (??) of values (float distance and float velocity with integer time)
Get the idea? First decide what data is represented, then try decoding it, see what gives "reasonable" values.
Of course, you will also have to look at the system which produced the data file, and decide whether it is likely to be big-endian or not.

How would i update an acces db from VC6,if the connectivity is done using ADO?
Do i use an update query separately,or do i open the DB and then make changes?
Detalied help would be really appreciated...thanks!
