Get the file icon by calling SHGetFileInfo() with uFlags as SHGFI_ICON and you'll get the HICON handle.
Get the ImageList of your list ctrl and add the file icon to it by calling CImageList::Add(), so that you can add that icon to your list ctrl. For adding new item to list ctrl, refer http://www.functionx.com/visualc/controls/listcontrol.htm[^]

The Demo is very good
I know how to set the icon now
Thanks a lot!~~~

Oh thanks for your votes.

here's the situation:
we have an application which uses an embedded instance of IWebBrowser2, and this browser is intended to be used on a site which requires a secure login. so, the user will bring up the browser window embedded in our app, login, and do his work. this works fine until the site in question has a pop-up window - when that happens, the embedded browser launches a new instance of IE for the popup, which means the popup doesn't get any of the security information / cookies from the main browser window, and it will force the user to re-login. we want to prevent that.
a poster here[^], suggests that the way to deal with this is to handle the NewWindow2 notification, create a new embedded browser in the handler, associate that with the main browser and let the new browser take care of the popup. i guess that sounds logical, but i'm not sure what that means in terms of new threads and new objects (and who cleans them up). the documentation is pretty weak, as usual.
so, has anyone else ever done anything like this ?

No have you. The KB seems straight forward. Let us know if it works will you?

Dude, I was serious. I would really like to know if that actually works in your situation.

hmmm. ok.
i'm still not sure of how to make it happen. but i'll let you know.
|
|
|
|

conclusion:
yes, it works fine. when the parent browser says it wants a new window, i create a new window (CWindowImpl, this is ATL), stuff a WebBrowser2 control in there and give the parent the IDispatch ptr to the new browser. no threads needed.
also need to handle window sizing and naming, but those are simple.

Wow that's pretty cool. And something that is relatively easy to implement using a browser so that's somewhat unique. Thanks for taking the time to post back!

Hi,
My application is setting the character set to DEFAULT_CHARSET , but using lfFaceName as "Tahoma" . Now when I type anything onto a dialog.. the text is turning to BOLD. Can I know whether this is proper.
Thanks,
Venkat

Your problem is Japanese character or font style?

I'd like to add visual xp style to my vc6 project, so I add a manifest file. It looks fine. But when the program exits, a exception will appear that shows "Access Violation". If I remove the manifest file, the program will normally exit.
Who can help me? Thanks!

Without seeing code its difficult for anyone to answer. As suggested already, you should use call stack to trace down the problem.

I have debugged but find nothing. The exception occurs at the function:
BOOL CObject::IsKindOf(const CRuntimeClass* pClass) const
{
ASSERT(this != NULL);
// it better be in valid memory, at least for CObject size
ASSERT(AfxIsValidAddress(this, sizeof(CObject)));
// simple SI case
CRuntimeClass* pClassThis = GetRuntimeClass();
return pClassThis->IsDerivedFrom(pClass);
}
Error message is "0xC0000005: Access Violation".
Another question: I have create a CAnimateCtrl in a CWnd. Normally, the backgound of the CAnimateCtrl is black. but when adding the manifest file the backgound is white!!

I have used objective grid in my project. I noticed when double click the cell and input will cause a debug error as follows:
memory check error at 0x01CE4DE3 = 0xBA, should be 0xFD.
memory check error at 0x01CE4DE4 = 0x0D, should be 0xFD.
memory check error at 0x01CE4DE5 = 0xF0, should be 0xFD.
memory check error at 0x01CE4DE6 = 0xAD, should be 0xFD.
Warning: You did start a redraw while the grid was redrawing its contents. You might consider delay this drawing by passing GX_INVALIDATE as parameter if possible or if you only call InvalidateRect() and do not UpdateWindow()
memory check error at 0x0488E583 = 0xBA, should be 0xFD.
memory check error at 0x0488E584 = 0x0D, should be 0xFD.
memory check error at 0x0488E585 = 0xF0, should be 0xFD.
memory check error at 0x0488E586 = 0xAD, should be 0xFD.
It should be related to manifest file. I don't know the former exit exception is also caused by objective grid and manifest file.
Looking forward to your help!

this is what i'm doing:
m_pD3D = Direct3DCreate9( D3D_SDK_VERSION ) ...
D3DPRESENT_PARAMETERS d3dpp;
ZeroMemory( &d3dpp, sizeof(d3dpp) );
d3dpp.Windowed = TRUE;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.BackBufferFormat = D3DFMT_UNKNOWN;
m_pD3D->CreateDevice( D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&d3dpp, &m_pd3dDevice )
...
D3DXCreateTextureFromFileEx(m_pd3dDevice, pSrcFile.c_str()
,D3DX_DEFAULT,
D3DX_DEFAULT ,
D3DX_DEFAULT,
D3DUSAGE_RENDERTARGET,
D3DFMT_A8R8G8B8,
D3DPOOL_DEFAULT,
D3DX_FILTER_NONE,D3DX_DEFAULT,0,NULL,NULL,
&(pStatData->m_Texture)))
after about 300 hundred textures from files it this returns D3DERR_OUTOFVIDEOMEMORY.
sizes are: I check the height (which is rounded to power of 2) of the returned texture at surface level 0.
first 100 textures of varying sizes, often small, 32 or 64 height on avergae.
then 200 textures all with 256 height.
I make sure to release() unused textures and directX resources and not making memory leaks in general.
The answer can be:
1. I should set some flag to make this all work.
2. I should load big textures with multiple images in them.
3. I'm passing some hard limit and I must cut down in the size of image resources.

Your description suggests an unidentified memory leak. Look for something that's not being freed. Maybe delete needs to be called for one of these objects.
If you can't find it, you can try the Signal Flare debugging pattern: Here, for one statement that allocates something, temporarily replace it with a loop that allocates 50 of them. Free the 50 where you were originally freeing the single object.
Then run your program and count how many textures it takes to run out of memory. If it's 300, that statement isn't the memory leak, so go on to the next one. If it runs out of memory after 6 textures (300 / 50), you've found the leak.
