When I use the RegSetValueEx API function to write a string (REG_SZ) to the registry, have I also write the NULL terminator to the registry?
What of the following source codes are right?
1.) without the '\0'
RegSetValueEx(hKey, _T("File"), 0, REG_SZ, (LPBYTE)(LPCTSTR) str, str.GetLength() * sizeof(TCHAR));
or 2.) including the '\0'
RegSetValueEx(hKey, _T("File"), 0, REG_SZ, (LPBYTE)(LPCTSTR) str, (str.GetLength() + 1) * sizeof(TCHAR));
PS: The code is for a Pocket PC application -> UNICODE!

The first one.
#include <beer.h>

I found another information in the MSDN doc:
<br />
LONG RegSetValueEx( <br />
HKEY hKey, <br />
LPCWSTR lpValueName, <br />
DWORD Reserved, <br />
DWORD dwType, <br />
const BYTE *lpData, <br />
DWORD cbData ); <br />
...
cbData
[in] Specifies the size, in bytes, of the information pointed to by the lpData parameter. If the data is of type REG_SZ, REG_EXPAND_SZ, or REG_MULTI_SZ, cbData must include the size of the terminating null character. The maximum size of data allowed in Windows CE is 4 KB.

I need my application to stop a USB device, so I do not get the windows 'Unsafe Removal' message when the device is disconnected. Anyone know how to do this ?
|
|
|
|

Hi,
Not sure how it can be done from an appln, but if u writing the driver for your USB device, and in the IRP_MN_QUERY_CAPABILITIES handler, if u set the following flag,
get the pointer to the current IRP and in that,
stack->Parameters.DeviceCapabilities.Capabilities->SurpriseRemovalOK = TRUE;
U will not get the Unsafe removal dialog..
regds,

This will not help me as my device is using some default driver. I wonder if it could be done via 'DeviceIoControl'. I am able to connect to my device by using CreateFile, but using DeviceIoControl with IOCTL_CANCEL_IO does not work (last error = 0x32).

Hello, I am using MSXML to get HTTP response from a webserver. The problem is when I use
pIXMLHTTPRequest.CreateInstance("Microsoft.XMLHTTP");
it always goes to error and can't continue to open the connection.
Can someone tell me where possibly the problem is, and why should I create the instance?
Many thanks in advance.

Try deleting your <projectname>.ncb file. Often does the trick.

If it is bmp, ico(no compress), You need the pic file 'head description', then jump to you place to read part of pic!
But compress pic data can't be read part!

EOF isn't actually a character in the file, it's something handled by the OS. It sounds like you're opening a binary file in text mode, so any bytes in the file that are 26 are interpreted as EOF (back in the DOS days, EOF was stored in the file as ^Z but only text files). Open it in binary mode so you can read the raw bytes without the OS or CRT doing any interpretation of the contents.

HI there  ,
Normally FTP Server breaks a connection if it is idle for a specified time period.
How can a FTP client know about the break up of connection due to time-out?
Is there any api, or is there any trick involved?
I am using WinInet classes such as CInternetSession, CFTPConnection etc.
Please heeelllppppp

Sir.....is it possible to access/use java class from VC++ ? If so...please let me know the mathod
Thanks a lot !!!!!!!

well I don't think it is possible...

Yes, but its ugly. We did it for a project at work. You have to use COM, which means you have to use MS J++ (or J# now) and expose a COM interface to be accessed from the C++ side. I don't know it well enough to go through the details.
If you are using .NET, then you should probably be able to access the J# Java classes seamlessly. At least that's what I've been told about VS.NET though I haven't played with it much yet.
There are only 10 types of people in this world....those that understand binary, and those that do not.

Thanks again.

Dear Guys,
Can someone help me how to display the Percentage ("25%") font inside a Progress Bar as the bar moves, the way it displays while installing some software.
Neel.

One solution is to derive a class from CProgressCtrl. A simpler solution is to download a module someone has worked on already. Look in CodeProject code section.

Dear Guys,
Can someone help me how to update an editbox control in a modeless dialog box on the fly. That is for example I've added this piece of code in "OnMouseMove" function.
CClientDC dc(this);
int xcordinate,ycordinate;
char str[100];
xcordinate = point.x;
ycordinate = point.y;
sprintf(str,"X->%d Y->%d",xcordinate,ycordinate);
dc.TextOut(600,20,str);
This code displays the X and Y co-ordinates on the fly in a SDI or MDI.What I mean by on the fly is you know, the way the number moves in a VCR while rewinding. The same functionality I would like to have inside a dialog box's edit box. I tried the usual m_edit=str; UpdateData(false) and SetDlgItemText but to no effect. It displays only the co-ordinate where the mouse was at first, but it doesn't update when I move it. Please Help.
Neel.
