UidFileName =c：\ user.trm

multiUserMode = 1

hUidFile = trm_Open（UidFileName，multiUserMode）



c.net 2010



[DllImport（@TRM.DLL）]

static extern int trm_Open（string pathFileName，int nMultiUser）;

public int trmOpen（string pathFileName，int nMultiUser）

{

返回trm_Open（pathFileName，nMultiUser）;

}





string filename =c：\ user.trm;

int mu = 1;

rtc = trmOpen（filename，mu） ;





我收到此错误。

Hi,

I have a VB6 program that call a dll. I''m converting the program to c.net 2010. I''m building under x86. The dll was created with PowerBasic.

VB6 Code

Declare Function trm_Open Lib "TRM.DLL" (PathFileName As String, MultiUser As Long) As Long

UidFileName = "c:\user.trm"
multiUserMode = 1
hUidFile = trm_Open(UidFileName, multiUserMode)

c.net 2010

[DllImport(@"TRM.DLL")]
static extern int trm_Open(string pathFileName, int nMultiUser);
public int trmOpen(string pathFileName, int nMultiUser)
{
return trm_Open(pathFileName, nMultiUser);
}


string filename = "c:\user.trm";
int mu=1 ;
rtc = trmOpen(filename, mu);


I''m getting this error.
An unhandled exception of type ''System.DllNotFoundException'' occurred in trmtest1.exe

Additional information: Unable to load DLL ''TRM.DLL'': Invalid access to memory location. (Exception from HRESULT: 0x800703E6)

Thanks,
Mark

推荐答案

将TRM.DLL放在应用程序的输出文件夹中，再试一次。

Place "TRM.DLL" in the output folder of your application, try again.
