API declare not allow

I have created a dll using C++, now i want to use it in VB6 However
the declaration is fine using the fullpath as follow:

VB Code:

Private Declare Sub Principal Lib "F:\myfunction.dll" (ByVal value As String)

However, i want to declare as:

VB Code:

Private Declare Sub Principal Lib app.path & "\myfunction.dll" (ByVal value As String)

VB wouln'd allow me to do that. any solution ?

Is dll located in app.path? Did you save your project? If you didn't, App.Path equals VB's path.

Do it like this and as long as the DLL is with the EXE or in the Search Path you should be set!

Private Declare Sub Principal Lib "myfunction.dll" (ByVal value As String)

Correct me if im worng... but if you register the dll in windows, the path should not be needed

Not all DLL's can be registered, right?

But as long as it is in the Search Path, where the .EXE is, or as Gavio states in the IDE it would need to be with VB6.EXE.

thanks guys

that is correct ;)

Place the dll in App.Path and try just,

VB Code:

Private Declare Sub Principal Lib "myfunction.dll" (ByVal value As String)

@Static, AFAIK, if the dll is a standard windows dll (not ActiveX dll), it doesn't (and can't be) need to be registered.
By default, Windows first searches App.Path for the dll. If it is not found in App.Path, then it searches the System dir. If it is missing in system dir too, then Windows displayes the Dll not found error message.
