FindResource() not working, need help.

[NoUse]

Was messing around with some code and came accross a problem that I've been trying to solve for a bit.

In theory, how could this not work:

   if(IS_INTRESOURCE(101) == FALSE){
       printf("101 is not a resource identifier...\n");
       return -1;
   }
   
   hResource = FindResource(hLibrary, MAKEINTRESOURCE(101), RT_RCDATA);
   if(hResource == NULL){
       printf("Error finding resource\n");
       return -1;
   }

hLibrary loads fine, and IS_INTRESOURCE does not fail but FindResource does. :/ Any idea as to what could be wrong?

Umm, thanks? But you don't know how long I've been studying that same msdn code :/ I still can't figure out the reason...

Where does the resource come from? (a DLL or the exe)
Have you tried NULL as the hModule?

Is hLibrary still valid?

What does GetLastError() return?

Resource comes from the exe.

Have you tried NULL as the hModule?

Yea that's what I'm using. Check the code at the bottom of this post.

Is hLibrary still valid?

Why would it become invalid?

What does GetLastError() return?

1812: ERROR_RESOURCE_DATA_NOT_FOUND :/

code:

   char shortpath[MAX_PATH] = {""},longpath[MAX_PATH] = {""};
   HMODULE modhandle;
   modhandle = GetModuleHandle(NULL);
   GetModuleFileName(modhandle,longpath,MAX_PATH);
   GetShortPathName(longpath,shortpath,MAX_PATH);
   
   HMODULE hLibrary;
   HRSRC hResource;
   HGLOBAL hResourceLoaded;
   LPBYTE lpBuffer;
   hLibrary = LoadLibrary(shortpath);
   
   if (hLibrary == NULL){
       printf("Error loading hlibrary\n");
       return -1;
   }
   printf("longpath: %s\n", longpath);
   printf("shortpath: %s\n", shortpath);
   
   if(IS_INTRESOURCE(101) == FALSE){
       printf("101 is not a resource identifier...\n");
       return -1;
   }
   
   hResource = FindResource(hLibrary, MAKEINTRESOURCE(101), RT_RCDATA);
   if(hResource == NULL){
       printf("%d\n", GetLastError());
       printf("Error finding resource\n");
       return -1;
   }

Thanks for the help, thus far.

Sounds like there is a resource defined as 101 but it is not binary data...
Remember that the resource ID# has to be uneque only to a dialog/window NOT the app.
In practice ID# can be repeated in a dialog depending on the msg handlers used.

Have you looked in the resource.h and found what is defined as 101?
Could be there is more than one resource with the ID# 101.

Try using the defined string rather than a number.
What type of resource are you trying to extract?


>>Yea that's what I'm using. Check the code at the bottom of this post.
Have you tried
hResource = FindResource(NULL, MAKEINTRESOURCE(101), RT_RCDATA);

>>Why would it become invalid?
Depending on the code, hLibrary could have lost scope ie non static variable in a callback function.
