I need copy an exe file when a button on my application is pressed.
I have created a resource by importing that exe.

insert->resource->import...

Now how can i get that file from the resource id and copy that into another location?
Is there a way?
Thank u.

struck here.

hResource = FindResource(NULL, MAKEINTRESOURCE(IDR_EXE1), RT_RCDATA);
if (NULL != hResource)
{
   hResourceLoaded = LoadResource(NULL, hResource);
   if (NULL != hResourceLoaded)        
    {
       lpBuffer = (LPBYTE) LockResource(hResourceLoaded);            
       if (NULL != lpBuffer)            
        {                
           // do something with lpBuffer here            
        }
     }    
}

I have loaded my one.exe into a resource with id IDR_EXE1 using wizard. now when im trying it with FindResource() it returning NULL. where is the problem?

If the function fails, the return value is NULL. To get extended error information, call GetLastError().

You don't create the resource of that file.
The problem is solved with the file reading and writing in binary mode.
as the path of your source exe file and destination file is fixed.
Just open the file in binary mode using ifstream and read it byte by byte
after reading flush the byte array to destination file using ofstream.

Ok
This is how i did it.

Create a Circular region. Using CreateEllipticalRgn().
Set the windows region to the created region.

Now load the bitmap. the bitmap will be confined to the created circular region.

Is this is the best method to do that?

Storing data in a DLL

Hello,

i need to protect some data (simple txt files). The idea here is just to protect data for wrong manipulation (i dont want to implement encryption at first place, 100 text files, i first thought i could zip/rar and use password but this seems bit unnecessary now)

I remember in one program, the data is stored in a DLL file.

My question is how i can store a simple text file in a DLL? or is it possible?

Thanks in advance.

Bekir.

How about as a RT_RCDATA resource?

Hello,

I have seen your article about using RT_RCDATA, thanks for the pointer.
I will give a try.

Thanks.

What's wrong?

Whats this API is returning ? I thing this call is failed. And probably, you need to set parent here.

This should probably be using the logical AND operator (i.e., you want to assert that both conditions are true, rather than just one of them).

He is refering to CWnd::ShowWindow code.

That's an unusual way of creating a pointer to a RECT. May I ask why you did not write?

LPRECT lprect = new RECT();

I'm just curious.
