Sounds fine. It is fine to display a message box in the worker thread - Although it is better if the UI thread does this as the worker can keep processing until the user makes his choice. Roger has a point when he makes his case for replacing SendMessage with PostMessage.

I want to show the thumbnails of html files to the user. As the thml file is of 600*400 I need to show the thumbnails in a list. So how do I convert the HTMl files output(the one which we see when we open the file in browser) into a image like bmp ot JPG

I dont really understand your question but from what i understand i suggest you open the Html file then press Print screen on your keyboard. Then open any image editor like MS paint then click paste and save your html file in any format you wish.
Hope this helps

I haven't personally tried any of this but here goes:
1. Use IViewObject::Draw to draw into a HDC that has bitmap selected into it.
2. Didn't Windows used to generate thumbnails of HTML pages? Win98 was it? I believe this functionality still exists.

With the SDK that comes with MSVC6 the declaration is not present. In the Feburary 2003 Platform SDK it's present. You need to download a newer Platform SDK from Microsoft. Download from here[^]. You can use this SDK with MSVC6.

and then use print screen to store the image

I'm trying to send mouse message to a application programmatically . I use win32 API SendMessage() to MS Paint (just 4 a test) to draw : SendMessage(hwnd_paint,WM_LBUTTONDOWN,0,position). There was no error but nothing happened. Is there something wrong ?

1. Manually do the mouse event and using spy++ try to find out the appropriate values of LPARAM and WPARAM
2. After a lbuttondown message, also post a lbutton up message.

To fake input you should use the SendInput function. See here for details (talks about keyboard input but a lot of what is mentioned still applies).

I used Spy++ to get parameter, and try to SendMessage. But it dosent work. I cant understand what happened ????

Using SendMessage or PostMessage message may or may not work, it depends on the program. As I mentioned the SendInput API is specifically designed for faking input. Here are some reasons the SendMessage/PostMessage technique may not work:
- The program calls the GetMessagePos to get the coordinated of the mouse when a message was posted.
- The program calls the GetAsyncKeyState to check for mouse buttons.
In short, the SendMessage/PostMessage may work, but then again it may not: it depends on how the program performs its input.

In my Project, i'm having 2 applications. i need to send and receive messages between the two applications. The first application should wait until it gets an acknowledgement from the second after sending the message. If i use WaitForSingleObject function, how can i carry this out? Please help....

Hello Owner drawn. As I said in my original message (the link), I don't receive such message! I don't know why :- ). I think I should, but I don't. As I said, it's a window created like this:
hwndControl = CreateWindowEx //Creating the window.
(
NULL, //ExStyles.
"Static", //Class name.
Text, //Text of the label.
WS_CHILD | SS_CENTER, //Styles.
0, //X.
0, //Y.
100, //Width.
30, //Height.
hwndThis, //Parent, a WS_POPUP window.
NULL, //Menu.
(HINSTANCE)hwndThis, //The handle of that WS_POPUP window which contains this one.
NULL //CreateStruct.
);
So it's a static label control... and it centers the text... but I can't change the background. So then I guess my question becomes, WHY DOESN'T IT RECEIVE WM_CTLCOLORSTATIC...
Weird!
