Downloading in Win32

[george7378]

Hi everyone,

I have the following code in my Win32 program which is supposed to download an image from the specified URL when I press the 'download' button, and then open it:

			
case IDC_DOWNLOAD:
HRESULT hr = URLDownloadToFile( NULL, L"http://www.url.com/image.jpg", L"image.bmp", 0, NULL );
system("image.bmp");
break;

However, when I compile, I get this:

error C2664: 'URLDownloadToFileA' : cannot convert parameter 2 from 'const wchar_t [69]' to 'LPCSTR'

I'm guessing that this is something to do with the fact that the URLDownloadToFile operation is only supposed to be used in console programs? How do I adapt it to work in Win32?

Thanks.

If you want to use unicode string, then you need to use the correct unicode functions:

HRESULT hr = URLDownloadToFileW( NULL, L"http://www.url.com/image.jpg", L"image.bmp", 0, NULL );

Go to Project Properties - General - Project Defaults - Character Set and change it to the Unicode character set.

OMG!...

This one tells pretty much everything.

error C2664: 'URLDownloadToFileA' : cannot convert parameter 2 from 'const wchar_t [69]' to 'LPCSTR'

Remove the "L" before your strings!
