Yes, out software environment has been fixed.
Since this was a small part of a large project, a large number of SDK upgrade would have to be done.

hi ..
i am trying to create an ODBC for database from vc++ application where i specify DSN i want and path for MSSQl
server database (data file *.MDF)
but i keep give me the error message the it "Cannot create data source"
this is the code:
=================
CString mdbpath=(CString)m_EFPATH;
char* szDesc;
int mlen;
szDesc=new char[256];
sprintf(szDesc,"DSN=%s: DESCRIPTION=: FIL=SQL Server: DEFAULTDIR=: DBQ=%s\0",m_EDSN,mdbpath);
mlen = strlen(szDesc);
int numPath=0;
for (int i=0; i
|
|
|
|
|
Two lines of code that are suspect:
sprintf(szDesc,"DSN=%s\0DBQ=%s\0", m_EDSN, mdbpath);
...
if (FALSE == SQLConfigDataSource(NULL, ODBC_ADD_DSN, "SQL Server", szDesc))
If SQLConfigDataSource() returns FALSE, what does SQLInstallerError() return?

Odd, as the docs indicate it should be one of eight ODBC_ERROR_xxx error codes.

Hi!
Is there a command that works like sprintf, but it is like strcat? Because I will catenate (probably wrong spelling) some hex numbers to the same char value.
Have a nice day,
Stefan

You can just use sprintf like this:
char buffer[1024];
char * tmp;
tmp = buffer;
tmp += sprintf(tmp, "Line %d\r\n", 1);
tmp += sprintf(tmp, "Line %d\r\n", 2);
tmp += sprintf(tmp, "Line %d\r\n", 3);
Another, and better, solution is to use a strstream:
strstream out;
out<<"Line "<<1<<endl;
out<<"Line "<<2<<endl;
out<<"Line "<<3<<endl;

If you use fixed number of hex numbers, use:
<br />
sprintf("%c%x%x", 'c', 0x544, 0xbff)<br />
or if you use variable number:
<br />
ostrstream os;<br />
os << 'c' << hex << 0x544 << 0xbff << ....<br />
and the char* string you obtain by os.str()

Here's a somewhat cheesy example:
char szBuffer[128];
for (int x = 0, num = 1; x < 10; x += 2)
{
sprintf(&szBuffer[x], "%02x", num);
num *= 2;
}

or even another choice:
CString S;
for ( int x = 0, num = 1; x < 10, x += 2 )
{
S.AppendFormat( _T("%02x"), num );
num *= 2;
}

i want to get jpeg data stream from a valid HBITMAP and transfer it through network. I can do this by first creating a jpg file and then reading the data from the file and at last sending it out,but it is not effective,so is there a more effective solution?(i don't want to get into the complexity of jpeglib)
(English is not my native language,sorry for my bad English)
|

Using the Intel Jpeg Library (IJL), you can convert to jpeg directly in-memory, allowing you to convert from DIB to jpeg and write the jpeg out to whatever medium you wish (file, socket, pipe, etc.).
onwards and upwards...
|
|
|
|
|
Thank you
a little problem,it seems that IJL only deals with the 24bit Jpeg files
|
|
|
|
|
Yes, that is correct. You will need to convert to a 24 bit jpeg. There is a really nice class called CDibImage (on CP, I think or available at http://www.naughter.com/[^]) by P.J. Naughter that makes these types of things really easy.
onwards and upwards...

How about ur own background application that will do the stuff after certain time. ??? you can make an MFC app a background application or go for ATL Service.
Hope i helped you in same way.

humm. Well i dont know about ATL Service running in win98 coz i have not developed application for 98.
Background apps. You make simple SDI application and in the initinstance you call HideApplication() this will make ur SDI application invisible. I.e it will be running in the background. I guess this will work in win98 also if you are using UNICODE.
First of all this application should go in the startup option so that it is launched every time it is rebooted.
you can keep track when was the last time the operation was done then accordingly you can do the next scheduled operation.
and of cource this application should set a timer to check for the scheduler operation every now n then.

Background process is a "program that runs in the baground" lets say an unvisible one  (hidden window to say it short)
About keeping record of the reboot, you can log the time when the application was started, and when it should update the files, and check on regular basis if the time is reached, or even has passes, and resync the files

Exceptions are errorenous program states from which it is still possible to close the program gracefully without losing data or crashing the system.
In C++, you can handle raised exceptions by using a try - catch block. You write the code you wish to execute in the try block, and then write either a conditional (specific exception) catch block or a generic one, if available.
Here is an example of handling an SQL-query exception:
try
{
CRecordset myRecordset(&db);
myRecordset.Open(...);
}
catch ( CDBException* e )
{
AfxMessageBox( e->m_strError, MB_OK );
e->Delete();
}For more hands-on information and how to write your own routines that raise exceptions, see MSDN Library for Exception handling topics (C++)[^].
Hope this helps,
