Hi...
Is this is correct way of using CImage & its functions?
Because using this also I was not able to load image.
HBITMAP hBitmap = NULL;
hBitmap = SHLoadImageFile(TEXT("windows\\dlrbtn_up_land.gif"));
CRect tr;
m_btnSeven.GetClientRect(&tr);
HDC hdc;
hdc = ::GetDC(m_hWnd);
CImage cImage;
cImage.Attach(hBitmap);
cImage.Draw(hdc,tr);

void setregvalue1 ( HKEY hkey, CString str_hkey, CString name, CString data)
{
HKEY childkey = 0 ;
DWORD dispos ;
RegCreateKeyEx ( hkey, (LPCTSTR) str_hkey, 0, NULL, REG_OPTION_NON_VOLATILE,
KEY_CREATE_SUB_KEY | KEY_ALL_ACCESS, NULL, &childkey, &dispos ) ;
RegSetValueEx ( childkey, (LPCTSTR)name, 0, REG_DWORD, (const BYTE*) (LPCTSTR)data, data.GetLength());

Are you passing the CString for type REG_DWORD.
I think it should be
DWORD dwValue;
RegSetValueEx ( childkey, (LPCTSTR)name, 0, REG_DWORD, (const BYTE*) &dwValue, sizeof(DWORD));
check this for information Registry Operations[^]

You've told RegSetValueEx() to expect a DWORD value, yet what you are passing is not. Try:
char *stop;
DWORD dwValue = strtoul(data, &stop, 10);
RegSetValueEx(childkey, name, 0, REG_DWORD, (const BYTE *) &dwValue, sizeof(DWORD));

Hi
In my apllication vc++ 6.0 i have 2 thread’s running ThraedA and ThreadB.
In ThreadB some process is keep going.
In ThreadA ,there is a button on clicking, it should send a message to ThreadB(which is busy on doing some other task).
Now my query is this, when ThreadA send a message to ThreadB ,ThreadB should immediately display the Received Message . how to do this ?
regards

Normally, a thread can't receive a message if it is a working thread. If it is a UI thread, then it can have a message loop and extract messages from its queue. Of course, it can only retrieve messages when it tries to do so and if it is busy doing something else, then you can't extract the message.
Typically, it is not really done this way: you set a flag (e.g. a boolean) in one thread which can be checked in the second thread.
What are you trying to do in fact ? Some context could be usefull to help you.

thanks for reply
As I mentioned above it is an UI Thread only.
My query is , I able to post a message to ThreadB , from ThraedA.
When ThreadB was free it receive the message and displayed it.
When ThreadB was doing some process ,it is not displaying the received message .
After completing the ThreadB process only it display this received message.
I want ThreadB to display the Message immediately, when message was posted from ThreadA.

As I explained in my previous post, this is not possible unless, you pump your message loop. This is done for example when you give back control to the MFC lib (when your function exits). It's still one thread so when you are busy in your function, nothing else will be processed for that thread.
Ok, but I also asked you a question: what are you trying to do exactly ? Give some context, it might help. What are you doing in that function that takes so much time ?
Anyway, it is also not a good idea to have lenghty function call in a UI thread, because your UI will be freezed during that time.

As Cedric said, you need to pump your messages, while you are busy doing something else. This means you need to add a message loop to your class , and call the loop several times while you are through a long process, to let all the awaiting messages come up.
Something like
MSG msg;
while (PeekMessage(&msg ...))
{
TranslateMessage(&msg);
DispatchMessage(msg);
}
Its never over !

How (e.g., message box, console, debug window)?

Hi,
I wrote one dialog application. For that dialog i have disabled Maximize button. In the context menu also it disabled the maximize button. But my problem is in task manager if i right click on my exe it is showing maximize option and it is maximizing the screen. How to disable this?

You can't do anything about that as your application can still be maximized by using ShowWindow() with SW_MAXIMIZE.

You could try responding to the WM_SIZE/SIZE_MAXIMIZED message with a 0. You could also remove the WS_MAXIMIZEBOX style from the dialog template.

Oh yes, I remember you: you are the guy who was spamming a lot of articles by posting almost empty messages but with a sig containing tons of links to your website as advertisment... And you continued to do so even when people told you to stop.
Sorry, but I don't support such behavior.

Hello,
[1]Using explict handle / local rpc(naclrpc) for rpc implementation.
[2]Following function is declared in inferface ".idl" file.
[callback] void DisplayString([in, string] unsigned char *psz);
The function is declared on client side as
void DisplayString(
/* [in] */ handle_t IDL_handle,
/* [string][in] */ unsigned char *psz
)
{
::MessageBox(NULL, (char*)psz, (char*)psz, MB_OK);
}
[3]Problem is server is calling the callback function DisplayString() and the function is getting called on client side but the "psz" paramter is not showing the value that the server is passing while calling DisplayString() function.
[4]Please put some light on the above issue.
Thanks.
