Hello,
I dont know, how to implementate a registration script
"hInstance needs to be the module / instance handle
of the module that contains your server registration
script (resource ID 102) .."
the server registration script is importand to
register my OPC Server.
RegisterServer()
HRESULT RegisterServer(void)
Return Values S_OK upon success, otherwise the result code
returned from the ATL registrar component.
The success of this operation is dependent on the application
including a registry script resource as part of its EXE.
The resource ID MUST be 102. An example resource script
is shown below:
HKCR
{
NDI.SimulationSvr.1 = s 'NDI Simulation Server'
{ CLSID = s '{1E52DE00-FA5E-11d2-91C6-F8E932000000}'
...
Best regards
Thomas

I'm converting a project from a VC++ ActiveX control to a C++ .net control.
The mouse button handling will change mode so that if left button is pressed on thing happens, right button does something else, and both buttons does another thing. This works OK but after having pressed both mouse buttons and then releasing one of the buttons the control loses capture (Control::Capture returns false). Under ActiveX/COM it didn't behave like this.
I've tried tracking the capture state during the mousedown and mouseup event handlers but still can't see what's going wrong.
Anybody got any ideas?
Thanks,
Dan

The method that the above site provides may be useful to send e_mail on the old smtp protocol servers. This kind of servers dont need the user name and password when they are connected to send e_mail. But now most of the e_mail servers update e-mail system for security and against rubbish e-mails.They ask users to provide user names and passwords to be connected.
to send mail,you should follow:
1、use socket to connect to the smtp server .
2、send "ehlo the smtp server \r\n" to the smtp server . you will receive the "250" from the smtp server,which stands for ok.
3、send "auth login \r\n" .then will receive the "334" from the smtp server.
4、send "your user name\r\n" which is encoded by the base64 arithmetic. you will receive the "334" .
5、send "your password"which encoded by the base64 arithmetic. you will receive the "235" that stands for ok.
6、so much to write.then follow the above site to continue.

. in a path means 'current folder'.
so, C:\.\.\.\.\myFolder means C:\myFolder...

The following code is for detect if USB disk is writable, it work well under Win2000, WinXP but not under Win98 where I got ERROR_FILE_NOT_FOUND error. Are these functions' parameters questionable or should I turn to another solution in order to make it work under Win98?
CString strDrive;
strDrive.Format("\\\\.\\%c:", A~Z);
HANDLE hDrive = CreateFile(strDrive, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_FLAG_NO_BUFFERING, NULL);
DWORD dError = GetLastError();
DWORD dwRet;
BOOL bWritable = DeviceIoControl(hDrive, IOCTL_DISK_IS_WRITABLE, NULL, 0, NULL, 0, &dwRet, NULL);

This[^] link should give you the information you need. There is link to a 2nd article on how to use DeviceIoControl for early versions of Windows. Since the logic is different, you will also need to determine the operating system you are running under to select the correct logic path.

hi,
When u r running in the winXp, the XP gives the driver automatically for the USB device. But in '98 environment user has to give the driver for device. so before accessing the USB device, load the driver for the USB device. This might be problem with this.

Per MSDN, this technique does not work for opening a logical drive. Specifying a string in this form causes CreateFile() to return an error.

hello,
I want to know what is the difference between debug mode and release mode. I started adn finished my project in release mode, how would it be different if it was done in debug mode.
Thanks,

Hello. The differences I came to think about (there might be other deifferences as well) is:
In the debug version, there is (of course) a lot of information that aids the debugger.
There are no code optimisations in the debug build.
Allocated memory is filled with nulls in debug mode.
More, anyone?

In debug mode, filling uninitialized memory with zero's makes it easier to see that your program has not initialized it.

See Gary R. Wheeler's answer, above.
But this difference in behaviour is a very common source of problems in release mode builds.

|

kakan is right, but to complete, just compare the sizes of your two generated (debug and release) exes...
you'll see the difference !

In Debug mode, all local variables not explicitly initialized by the program are initialized with 0xCC.

This is backwards. You should develop and test it in Debug mode, and only when all of the bugs have been removed should you compile it in Release mode.

In debug mode, two things happen.
First, the compiler generates information about your program used by the debugger. The compiler also generates code to initialize memory to default values.
Second, in debug mode you run your programmer under the debugger. The debugger lets you step through your code, examine data as the program executes, set breakpoints, and perform other operations. The purpose of the debugger is to let you run your program in a controlled fashion so that you can see what it is doing as it runs.
In release mode, the compiler doesn't initialize memory for you; it assumes your program will initialize what it needs. As a rule, in release mode the compiler will also 'optimize' your code. In simplest terms, the compiler generates machine code that runs as fast as possible. The machine code in this case looks different from the debug version, since the compiler can rearrange operations in order to improve efficiency.
As someone else has mentioned, you really want to run your program in debug mode first. This lets you get things working in a controlled environment. After it looks like things are working correctly in debug mode, rebuild the program in release mode, and test it again. There are subtle differences between debug and release. The article Debugging Release Mode Problems[^] has more information.
