HInstance is of the main application and cannot find RES1.How can I access the package to retrieve RES1 ? If you know the name of the module that contains the resource, you can use GetModuleHandle() to get its instance handle and use that to load the resource. If you do not know the name of the module, you have to enumerate all of the modules loaded by the application (see LibModuleList) and try each one until you find the resource you are looking for. - Dennis Back to top HF Guest Posted: Mon Feb 06, 2006 8:01 pm    Post subject: Re: HInstance of Package thanks guys, No the code is bb->LoadFromResourceName((int)HInstance ,"RES1"); I checked my .exe file with resource editor and doesn't contain the bitmap. Instead the package (bpl) it contains the bitmap.So the problem is why during built , final .exe doesn't take the bitmap resource from package.azny idea ?

If you want the bitmap to be in the EXE, you have to add the resource to the EXE's project. If the resource is in the package's project, then you have to load the bitmap from the package, not the EXE. I think that this depends on whether the package is linked statically or dynamically. A quick Google turned up that you probably need to add #pragma resource "xxx.res" to the component's .cpp file.

See my first reply for how to do that. - Dennis Back to top Dennis Jones Guest Posted: Mon Feb 06, 2006 9:00 pm    Post subject: Re: HInstance of Package "Jonathan Benedicto" <invalid (AT) nobody (DOT) com> wrote in message news:43e7a6e8 (AT) newsgroups (DOT) borland.com...

A quick Google turned up that you probably need to add #pragma resource "xxx.res" to the component's .cpp file. Ah, yes, there are some oddities when using resources in packages that are linked statically, and as I recall, that just might be one of them. If the package is linked statically, then it's a matter of figuring out how to make sure the EXE gets the resource, and I think you're right that pragma is the solution. If the package is linked dynamically however, then I think the only option is to load the resource from the package directly using its instance handle. - Dennis Back to top HF Guest Posted: Tue Feb 07, 2006 1:01 am    Post subject: Re: HInstance of Package Ok . resolved Instead of adding the .rc or .res via the IDE to the package I added it with #pragma resource "icons.res" in the unit.cpp (not the package source file) and it showed that is ok during building the calling application ,when asked for icons.res to link it. thanks guys.
