Is there any way to find that the file is transfered successfully.

If either if the if() conditions in the while() loop fail, you know the transfer was unsuccessful.

I am trying something like Spy++ for html documents to identify child window controls on the html page rendered by a browser. Is there a way I can programmatically access the common controls like button, edit window etc from a html page after the page got rendered in a browser like firefox, IE, Opera etc.

Thank you

cheers

I hope you have to create the proxy class from your server wsdl file, which you can use in your code directly.

Try using wsdl.exe (.net tool) to build proxy class from the WSDL url.

You need to read a book on MFC (if you are any good at Windows programming, then you could skip other chapters, just read the basics of the framework and jump on to the chapter that talks about dealing with bitmaps and GDI in MFC). After you finish it, you will be all set to go. Cool | :cool:

hello all

i am using VS 6.0, VC++, Win32

My Task is to display png image on Transparent window.....

i used SetLayeredWindowAttributes to make my window transparent and it works fine......but the problem is my image also gets transparent and nothing is displayed ......

can anybody suggest me how to overcome this problem.....i.e only window should become transparent but not the image.....

Thankx:::

You can use an image with a solid colour applied in the parts that should be transparent. You then display the image using alpha keying, which renders the image except pixels that are this colour.

Here is code that displays an an image with 75% opacity, except for pixels that are RGB(255,0,0) - which are not displayed at all.
SetLayeredWindowAttributes(hwnd, RGB(255,0,0), (75*255)/100, ULW_COLORKEY|LWA_ALPHA);

If you remove the |LWA_ALPHA part, you get full opacity on all pixels except the red ones, which are not shown at all.

Oops, sorry about that - i forget which one it is, you need one of these #defines (I think it's the first one)

#define _WIN32_WINNT 0x0601
#define _WIN32_IE 0x0300

Re: Transparent Window using SetLayeredWindowAttributes

in both #defines i got the same error as

I think you need one of these (put that into the PreProcessor settings of your project):
_WIN32_IE=0x0500
WINVER=0x0500
