No Entry Point Found In Dll

[cftygv]

Hi,

I have a dll that was developed in VC ++.
I need to call the API in C#.
But on run timr iu get an error that no entry point found for function ... in DLL.


and when trying to call the function TApiInitialize or any other function i get an error.

My code in c# is :
DllImport("TickerApi.dll")]
public static extern void TApiShutDown();


public void test()
{

TApiShutDown

}

Please advise !!!!

I have the h. file:
