Hello  MAHESH
pls examine my code given above
I would like to add a resource  thru code

UpdateResource(hWnd,RT_HTML,"PRICE", MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),lpBuffer,dwFileSize) != FALSE)



>>>Try giving the resource a string name instead of a numeric identifier.  this is done by openiing its 'Properties' box and wrapping its 'ID' in quotes.
>>>eg. So PRICE becomes "PRICE", and aaa becomes "aaa".

------------------------

--------------------Configuration: Mod2 - Win32 Debug--------------------
 
E:\VC\Mod2\Mod2Dlg.cpp(260) : error C2664: 'FindResourceA' : cannot convert parameter 1 from 'void *' to 'struct HINSTANCE__ *'
        Conversion from 'void*' to pointer to non-'void' requires an explicit cast
 


----------------------

whats wrong  with the code

HANDLE      hExe;
HRSRC hRes; // hand of the Re
      // TODO: Add your control notification handler code here
//Load the EXE -EBOOK.exe

hExe=LoadLibrary("E:\\VC\\Ebook\\Debug\\Ebook.exe");

if (hExe==NULL)
{
      MessageBox("Error");
}
 
// FIND THE RESOUCE PRICE

hRes = FindResource(hExe,  "PRICE",RT_HTML);
if (hRes == NULL)
{
   MessageBox("Could Not Locate the File");
}

typecast it with HINSTANCE

do like this..

hRes = FindResource((HINSTANCE)hExe,  "PRICE",RT_HTML);

>I am getting msg What is the wrong with it

it means FindResource() function cannot locate resource "PRICE" in executable module..

MAHESH

But
 I am adding from Button1 Click Event







void CMod2Dlg::OnButton1()
{
     // TODO: Add your control notification handler code here


 

HANDLE hFile;
DWORD dwFileSize,dwBytesRead;
LPBYTE lpBuffer;


hFile = CreateFile("C:\\price.html", GENERIC_READ,

                   NULL,
                   OPEN_EXISTING,

     if (hFile != INVALID_HANDLE_VALUE)
     {
// GET FILE SIZE
                   
               dwFileSize=GetFileSize(hFile,NULL);
               // GET THE BUFFET SIZE
               lpBuffer= new BYTE[dwFileSize];

                    // READ FILE INTO tTHE BUFFER
               if(ReadFile(hFile,lpBuffer,dwFileSize,&dwBytesRead,NULL)!=NULL)
               {


               }

               //relase the file

hWnd=BeginUpdateResource("E:\\VC\\Ebook\\Debug\\Ebook.exe",FALSE);

if (hWnd==NULL)
{

     if( UpdateResource(hWnd,RT_HTML,"PRICE", MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),lpBuffer,dwFileSize) != FALSE)
          {

          }
     else

     {
          MessageBox("Failed to Add The File");
     }

I will suggest you to test your executable file after adding resource.. I will suggest you to use tool like PE Explorer or Resource Hunter to browse all resource in exe/dll.. its here..u can download

http://www.boilsoft.com/rchunter.html
http://www.pe-explorer.com/

with this u can cross check if your exe file is really importing a resource from ur code..

MAHESH

I have also tired with the following  


  I have added a HTML file in my first app . Manually from the Property Sheet gave it the name as "INDEX"
While trying to read it
as hRes = FindResource((HINSTANCE)hExe,  "INDEX",RT_HTML);
I can read it

and also can successfully Read  ABOUT DIALOG BOX

hRes = FindResource((HINSTANCE)hExe, MAKEINTRESOURCE(IDD_ABOUTBOX) , RT_DIALOG);

So it is assumed that While I am trying to add the "PRICE" html file , It not added
How can I check it whether it is added or not

code to add the Price.html is

 UpdateResource(hWnd,RT_HTML,"PRICE", MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),lpBuffer,dwFileSize)

download resource hunter and browse ur executable check its having html resource name "PRICE"..refer above links for download

MAHESH

I have downloded the PE explorer.

I donot find any entry for my Price.html

why such things are happening?
Why my code ,mentioned above, can not update the resource?
What should I do now?
