I'm pretty sure there is something trivial that you are missing, but I don't do windows event loops enough to tell you what.

As an alternative, that might be better: have you considered using threads? use one thread to read this message, and when it changes post a message to the main thread. (In some systems you can update the window from that thread, I'm not sure about windows) Threads have their own problems, and are difficult to work with on some levels, but it might be better.

Loren,
Have you thought about using the timer event. In the OnInitDlg section of your code you could create a timer that calls the OnTimer event. Have it run every second. Then you can let the rest of your program do what you want it to do. I have this running a clock in a status bar. Work great.

how to customize the 'Cookie' http header of Internet Explorer

Hi all.

I am trying to customize the cookie data in the http headers of my IE. That is to say I must add my own 'Cookie' header to standard IE http headers. But, each time when I use IWebBrowser2::Navigate2() function to add 'Cookie' header(such as 'Cookie: jsessionid=0DE9IIUD03D23'), the 'Cookie' header will be filtered by IE. It seems that the 'Cookie' header is maintained by IE itself and it is not changeable.
Is there any way to modify IE's 'Cookie' http header according to you need?

Any suggestion will be appreciated.Thanks very much.

Leo. Confused | :confused:

Like:

LPHOSTENT lpHostEnt = gethostbyname(szHost);
if (NULL != lpHostEnt)
{
    memcpy(&(dest.sin_addr), lpHostEnt->h_addr_list[0], lpHostEnt->h_length);
    strIPAddress = inet_ntoa(dest.sin_addr);

Make links in RichEdits clickable?

Hi!

I have problems making URLs in RichEdits clickable.

What I have done so far:
1) Added the ENM_LINK flag to the SetEventMask parameter
2) Send a EM_AUTOURLDETECT message to the RichEdit with WPARAM = TRUE
3) In OnNotify, check for the EN_LINK message in NMHDR.

But unfortunately the OnNotify message never receives a message from the RichEdit control. Also the links don't get blue and underlined automatically Cry | :((

Any idea???

Confused | :confused:

dragging controls

I have a procedure that creates a new instance of my CListCtrl-derived object on the screen in a random position when the user clicks a button. That works fine. But I'm trying to let the user then drag the control around on the form once it's there and I'm trying to use the MoveWindow() function, but I'm doing something wrong. Here's what I have so far:

if(nFlags == 1)
    {
        CRect rect,rect2;
        int x,y,rectx,recty;
        x = point.x - prevPoint.x;

        y = point.y -  prevPoint.y;

        
       
        this->GetWindowRect(&rect);
               
        this->MoveWindow(&rect);
               

    }
    CListCtrl::OnMouseMove(nFlags, point);

after making sure that the left mouse button is down, I was trying to move it according to the position it was in when the mouse was first clicked, but that wasn't working, so I just tried to do it with the exact same coordinates and everytime I try to move it, it just appears a couple hundred pixels off to the right and down. (there's code left in from what I was trying at first also)

If it's broken, I probably did it

Perhaps the code is using screen coordinates but needs client coordinates, or vice versa. Check out ScreenToClient() and ClientToScreen().

Scroll bars in CStatic-derived class!!!

How to implement a scrollbar in CStatic-derived class. When I wrote:

EnableScrollBarCtrl(SB_HORZ);
SetScrollRange(SB_HORZ, 0, 100);
ShowScrollBar(SB_HORZ);

I can see a scrool bar but I can't control it. WM_HSCROLL don't received too.

What's a problem. How to implement it.

You might need to experiment with setting the notify-style and having an ID other than IDC_STATIC, but I would recommend that you use a CWnd-derived class instead of a CStatic instead.

IDataObject to Bitmap

tunerica2-Jul-04 1:33

tunerica

2-Jul-04 1:33

I have captured a frame from a video stream using capEditCopy, then created a IDataObject pointer called frame1,

IDataObject * frame1;

then used OleGetClipboard with frame1,

OleGetClipboard(&frame1);

Now as I understand this, and I don't understand this all that well, this means that the frame1 is now a pointer to the data that was placed on the clipboard with capEditCopy. If this is true, how do I know that it is grabbing the right stuff from the clipboard, if this is not true, can anyone suggest a way to get the data from the clipboard.

My aim is to get the data in some format, bitmap for example, that I can examine the RGB values of each of the pixels in the frame. What I don't understand also, is, what format is the data associated with frame1, I assume IDataObject. How can I turn this into a bitmap where I can examine the pixel values. Is this what the GetData function does, and if so how do I use it?

Any help with this would be very much appreciated. Thankyou in advance.

The question is off-topic, but as the answer is quite simple, I'll bite:

No idea Smile | :)

But you should be able to figure this one out yourself (especially as it sounds like a homework-question). Will the library contain many books? The books contain many libraries? Can a loan belong to several people? Can a person have several loans? Go on like this, and you have solved the multiplicity (this is fun!)

The association, is a library a part of a book? A book a part of a library? A loan a part of a book? A book a part of a loan? Will the part outlive the whole?

And dependancy, is a library a part of a person, or is the library only using the person? Or vice versa?

Smile | :)
