Actually this code Resolve the link file path.

I want that can extract the link file path from target file path.

so, you have a file "Foo.exe" and you want to find all of the shortcuts that point to it ?

i'm 99% sure you can't do that. targets don't know about links to them.

But we can do a scan in the registry to find out all valid link files pointing to what, and sort the targets to group the identical target.
But ... err ... it takes long time. Unsure | :~

WinASO[^] registry optimizer tool does this way (I guess) to remove invalid links (shortcuts and references in registry).

right, that's the brute force way. (you could also scan all connected drives for .LNK files, resolve them and find those that point to your target!)

but AFAIK there's no simple way to do it, like there is in the standard direction.

converting code from vc6 to vc2005

Hi all,

I have written a code in vc6 in which i have written this code for getting a resource handle....

FindResource(NULL,MAKEINTRESOURCE(IDR_IDR_EXE_EXEEXTRACTOR),"IDR_EXE");

now when i am writing this same code in VC2005

it gives an error:-
error C2664: 'FindResourceW' : cannot convert parameter 3 from 'const char [8]' to 'LPCWSTR'

but error is resolved when i add prefix 'L' to my third parameter

FindResource(NULL,MAKEINTRESOURCE(IDR_IDR_EXE_EXEEXTRACTOR),L"IDR_EXE");

now my problem is...
it compiles correctly but at runtime its giving debug assertion failed error.

Is there any other way to Find my resource in VC2005

It's because UNICODE is enabled by default in VC2005, which was not the case with VC6.

Well, you don't provide a lot of usefull information do you ? What is the exact problem ? Where does your code crashes ? Use your debugger to locate the problem more precisely and inspect the state of the different variables before the crash.

Try

FindResourceA(NULL,MAKEINTRESOURCEA(IDR_IDR_EXE_EXEEXTRACTOR),"IDR_EXE");

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Thanks for your solution it implemented correctly.

now i am having same problem with UpdateResource

VERIFY(UpdateResource(hUpdateRes,L"IDR_EXE",MAKEINTRESOURCE(IDR_IDR_EXE_EXEEXTRACTOR),MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL),
buff,nSize));

same error if i remove it

error C2664: 'UpdateResourceW' : cannot convert parameter 2 from 'const char [8]' to 'LPCWSTR'

how can i use it in VC2005

I think you can go on using the same approach, i.e.

VERIFY(UpdateResourceA(hUpdateRes,"IDR_EXE",MAKEINTRESOURCEA(IDR_IDR_EXE_EXEEXTRACTOR),MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL), buff, nSize));

anyone can help me to explain code below?

CStatic is a MFC class (WIN32 doesn't have wrapper classes). And C doesn't have classes neither.

m_hbmp=m_vicImg.hBitmap;

Assigns to this object's (a CDialog derived class?) m_hbmp member (probably a HBITMAP, i.e. a Bitmap handle) the value of m_vicImg.hBitmap (i.e. the member hBitmap of the m_vicImg object (that you only know and probably is another member of this object).

li zhiyuan wrote:
CStatic *pImgPicture=(CStatic*)GetDlgItem(IDC_staImg1);

Gets a pointer to a CStatic object representing the dialog static control having ID equal to IDC_staImg1.

li zhiyuan wrote:
pImgPicture->SetBitmap(m_hbmp);

Calls the SetBitmap method of the CStatic object. This should change the bitmap represented by the dialog static control.

BTW You can also get some information reading MSDN documentation.

You can declare a variable for static control instead make a pointer.

My Visual Studio Browser keeps attempting to search for items on the web instead of my pc. What can I do to disable this feature ?
I am using visual Studio 97. I tried uninstalling and reloading Visual C++ 5, made no difference.

And all I get is This Program Cannot Display the Web Page. I am running Xp Home Edition.

Thanks

I am not sure exactly in which place to edit.
Is you machine is connected to a Network (Lan or wan or anything)
if it so then there will be a file in which you will be giving
the host name list. there you have to go and and remove the unwanted
ip. that may solve your problem. I am sorry i cannot recollect
the file name. I m extremely sorry for my poor memory.
