DLLImport error: System.AccessViolationException with Manifest file and c#
- by RP
When trying to call (DLLImport) an external c++ dll from a .net application that has a manifest file with requireAdministrator, I get this error trying to call function from the C++ dll in Windows 7 with UAC enabled.
Method I am calling: EnCrypts
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
public class BlowFish
{
[DllImport("BlowfishTool.dll", CharSet = CharSet.Auto)]
public static extern String EnCrypt(String strData, String strPassword);
[DllImport("BlowfishTool.dll", CharSet = CharSet.Auto)]
public static extern String EnCrypt(String strData, String strPassword, bool doNotUsePassChecking);
[DllImport("BlowfishTool.dll", CharSet = CharSet.Auto)]
public static extern String DeCrypt(String strData, String strPassword, bool doNotUsePassChecking);
[DllImport("BlowfishTool.dll", CharSet = CharSet.Auto)]
public static extern String DeCrypt(String strData, String strPassword);
public static String EnCrypts(String strData, String strPassword)
{
return EnCrypt(strData, strPassword, true);
}
}
}
