Program Resources

[ExciteMouse]

I am making a program that needs to load a resource other than a BMP,ICO,CUR,String.. or any basic resource.. its an HTML file..

So i added it to the resources of my program, so how to i load it into a varible.. lets say a char or CString?

thanks

unsigned long ulLen;
unsigned char *pubData;
void *pRawData;
HRSRC hRes;
HGLOBAL hStub;

hRes = FindResource(hModule, MAKEINTRESOURCE(IDR_DATA1), RT_RCDATA);
ulLen = SizeofResource(hModule, hRes);
hStub = LoadResource(hModule, hRes);
pRawData = LockResource(hStub);
pubData = new unsigned char[ulLen];
memcpy(pubData, pRawData, ulLen);

After that, pubData is a pointer to a memory block with your data in it, of length ulLen. So, if it's a character string, you could do:

cout << pubData << endl;

That's as long as the data in the resource ends with '\0'. Otherwise, you'd need to use:

for(int i = 0; i < ulLen; i++)
    cout << pubData[i];
}

i need to know how to get the `hModule` of my app.
in order to load resource the first parameter has to be a HMODULE..
im using MFC.

[ExciteMouse]

would this be the correct way?

const char* mes = AfxGetApp()->m_pszAppName;
char APP_PATH[MAX_PATH];
memset(&APP_PATH, 0x0, MAX_PATH);
sprintf(APP_PATH, "%s.EXE", mes);

HMODULE hModule = LoadLibrary(APP_PATH);

that would get the APP name and then load it. It doesnt return NULL.. so i guess its working.

[ExciteMouse]

ok nothing is working... im sure your code works.. but i cant get the HMODULE of my app...
when i call LoadLibrary.. it returns 0x00400000
so i assumed it works.. then when i use your code FindResource returns NULL.

any other ideas?

i just had to use RT_HTML
since it was defined as a HTML resource
doh!
ok man thanks tons again!

To get a module handle under MFC, use AfxGetResourceHandle().

Hello!

I did a search (rather than reposting an already-asked question) and saw this, but I can't get it to work... is there some way I have to add the resource (I'm using MSVC++)?

Thanks

You have to insert a user-defined resource.

[Dreamlax]

I did, but I found that the problem comes when the program gets to memcpy.

[CornedBee]

Are you sure you use the correct resource name? Have you tested the raw pointer for NULL?

[Dreamlax]

Yeah I fixed it, instead of RT_RCUSER I had to use (LPTSTR)"BINARY"... I dunno why, under the resource view it doesn't have any groups called binary but oh well it works now!

[CornedBee]

What you specify is not only the group, but also the individual resources name, I think you got those two confused.
