CVI and DLL creation including libxml2

[AAAAAAAAAAAAAAAAAAAAAA]

Good afternoon,

I am using CVI 2017 ,and especially i do build a specific DLL (lets call is DLL_A). This DLL includes some fucntions from the library libXML2.

And when i am loading and calling my DLL_A, i have an issue (error -25) which is due to the fact that this DLL_A, includes some codes that needs some function defined in the LIB/DLL provided by LibXML2. And it s not possible to load 2 dll in the same time.

So is there a way to fix this kind of issue whithout having to refactor the code?

Thanky ou

If a DLL could not depend on other DLLs, no Windows application could work ever since the entire Windows API is one huge collection of DLLs that depend on each other.

Yes , indeed, it looks strange.

But i am trying to find why this DLL is failing to initialize when i use GetExternalModuleAddr .., since it returns a status error=-25.

And when i comment the calls to the libxml2 library, the error disappear...

So i am trying to guess why this libmxl2.lib is giving me issue..

Try to use the Windows APIs LoadLibraryA() and GetProcAddress() instead. The GetExternalModuleAddr() is a legacy function that does add nothing to the loading of DLLs under Windows.
