Um, That definately was working when I posted the message. Perhaps the site is having problems at present. 
I am not sure where the site is hosted but in Manchester UK there was a fire recently that took out many phone lines and sites. They are still reparing the damage.
Give it a while and try again later. It's definately worth a look at.

I wrote a Service prog and create a window in this service to receive remote program's user defined(WM_user+2330) message.but everything is fine except the window cann't receive message.
anyway,my servicetype is SERVICE_INTERACTIVE_PROCESS,why?
thanks a lot!

I am using TSAPI writing a CTI service prog.
in TSAPI,using function(acsEventNotify) allows an application to request that a message be posted to its application queue when an incoming ACS event available.
when Telephony server's receive queue become non-empty,then it would post a msg(user defined) to application,and after application received this msg ,it will get the msg from receive queue to process.
RetCode_t acsEventNotify
(
ACSHandle_t acsHandle,
HWND hwnd,
UNIT msg,
Boolean notifyAll
);
hwnd: the window which receive notif
msg: user-defined msg to be posted when an incoming event become available.
so in my service,i create a window to receive this msg.but i can't receive any msg.however,when my prog is application,it can run correctly.why

someone can help me how to convert text to wave (don't use sapi of microsoft)???
thanks

It's probably affordable to write a web service that sends the text to a call centre in India and takes back an mp3.
Seriously, that's a hell of an ask. If Microsoft provides a speech API, why don't you want to use it ?

Hi
I am currently building a computationally-heavy application, which requires processing of hundreds of image data, and this processing must also be done hundreds of times. To let users know which image file is currently processed, I simply bound a variable to a static text control, and I update this variable and call UpdateData(FALSE) everytime a new image file is processed.
The application runs fine for the first few iterations. But after it reaches a certain iteration (the exact numbers differ between executions, but they are close to each other), the text control suddenly moves to the topleft of my monitor! Updating of the control is also abnormal (some image files are skipped). Apparently the processing still runs fine, and the result is correct, it's just that the update is messed up.
Could someone shed some light on what may cause this problem and how I can rectify this?
Thanks!

I'm guessing that the image processing is done in a different thread than the main application so as to keep the GUI 'snappy'.
If so, there could be an issue with one thread manipulating a window created by another (the main app) thread. This could cause the app to screw up at random. I have seen similar effects related to this before.
I would suggest that the image thread post (not send) a message to the window. The app thread can then update the variable and call UpdateData(FALSE).

Hi,
I've been working on an image based application. I'm using VB and VC++ to work with the images. Both are activex controls. I created a property like Get/SetActivePicture(LPPICTUREDISP pPicture). The code is given below.
I'm facing memory problems. Can someone help me how can I release the memory from VC++ after I use the picture object? Thanks in advance .. I can't release the component until I solve this issue. Pls. somebody help me.
The implemenation in VB is like this ... After using this, the virtual memory has been increasing each time ... the performance became too slow !!! 
....
PicEd.Open("C:\Temp.bmp")
set PicEd.ActivePicture = Picture1.Picture
PicEd.RotateBy(90)
set Picture1.Picture = PicEd.ActivePicture()
....
//----------------------------------------------------------------------
void CPicEdCtrl::SetActivePicture(LPPICTUREDISP newValue)
{
// TODO: Add your property handler here
if (newValue == NULL) return;
try
{
HBITMAP hBMP;
HRESULT lResult;
newValue->AddRef ();
m_Pic.SetPictureDispatch(newValue);
newValue->Release();
lResult = m_Pic.m_pPict->get_Handle((OLE_HANDLE FAR *) &hBMP);
//CxImage* image;
image->CreateFromHBITMAP((HBITMAP)hBMP);
}catch (CException e)
{
e.ReportError();
e.Delete();
}
SetModifiedFlag();
}
// ------------ ---------------------- --------------- ------
LPPICTUREDISP CPicEdCtrl::GetActivePicture()
{
// TODO: Add your property handler here
if (image == NULL)
{
m_Pic.CreateEmpty();
goto EndProp;
}
try
{
m_Pic.CreateFromBitmap (image->MakeBitmap(0));
}catch (CException e)
{
//Suppress any exceptions
e.Delete();
m_Pic.CreateEmpty();
}
EndProp:
//return the IPicture dispatch interface
return m_Pic.GetPictureDispatch();
}

I am new to (attempting) to use template classes.
My requirement is to avoid coding using inheritance - becuae I have 13 classes already coded and I want to have two "new forms" of classes that "inherit" this class and another class. To clarify...
I have a class X and I wish to make a class publishedTrack and a class reflectedTrack.
For example: I was hoping to use
typedef PublishedObject< Track > PublishedTrack ;
PublishedTrack* publishedTrack = new PublishedTrack;
where
template < class T >
class PublishedObject
{
private:
p_;
public:
PublishedObject();
virtual ~PublishedObject();
operator T*(void) { return p_; }
T& operator*(void) const { return *p_; }
T* operator->(void) const { return p_; }
PublishedObject& operator=(PublishedObject<t> &p_)
{ return operator=((T *) p_);}
PublishedObject& operator=(T* p_)
{ p = p_; return *this; }
T* get() const { return (T*)p_; };
}
I also want to be able to do publishedTrack->someMemberFunctionInTrack()
But what I get is that my operator overloading of -> is not quite right.
Any advice...any "pointers" ?

|
|
|
|
This is just a wild guess but perhaps instead of overloading the -> operator you could try overloading the . operator? ... Like I said, a wild guess...

Anyone know where I can get my hands on some C/C++ (not Java) code to control an X10 device? I just want to be able to turn the device on and off by running a simple command line program, eg:
C:\> foo.exe ON
C:\> foo.exe OFF
There seems to be nothing available @ x10.com or SourceForge.
Thanks!

How do I convert a CString into a DWORD or to a INTEGER.
Basically suppose I have a function that returns a DWORD value , but the acutal value that I need to return is in a CString. (actually ...it is a number between 0 - 100)
suppose...
DWORD myfunc()
{
CString strVal="5.5";
DWORD retVal = {some how convert the strVal into an integer or DWORD};
return retVal
}

Use _ttol() to convert a CString to an int.
