从具有结构指针的VB.NET调用C ++ DLL函数 [英] Calling a C++ DLL function from VB.NET having structure pointer

问题描述

我正在使用DLLImport从我的VB.NET项目中使用C ++ DLL.但是我还没有在VB.NET中处理指针的经验.

C ++函数调用&声明在下面.

Hi,

I am using C++ DLL from my VB.NET project using DLLImport. But I have not experience of how to handle the pointer in VB.NET.

The C++ function call & declaration is a below.

EXTERNC T_PDU_ERROR PDUGetModuleIds(PDU_MODULE_ITEM **pModuleIdList)

where 

typedef struct {
T_PDU_IT ItemType; 
UNUM32 NumEntries; 
PDU_MODULE_DATA *pModuleData; 
} PDU_MODULE_ITEM;

typedef struct {
UNUM32 ModuleTypeId; 
UNUM32 hMod; 
CHAR8 *pVendorModuleName; 
CHAR8 *pVendorAdditionalInfo; 
T_PDU_STATUS ModuleStatus; 
} PDU_MODULE_DATA;

请告诉我如何从VB.NET应用程序中使用C ++ DLL.

在此先感谢

看看 Pinvoke [ ^ ]网站.它没有针对您的特定情况的条目，但是您可以从其他示例中很容易地弄清楚您需要做什么.

Take a look at the Pinvoke[^] site. It does not have an entry for your specific case, but you can figure out what you need to do from the other samples quite easily.
