Problem in Passing 1d array from VC++ to VB [modified] - COM Discussion Boards

want to close MSWord after sending e-mail via Outlook

15-Feb-07 11:08

Hello,

1. Have you initialized all your variables inside com server? Some memory garbage can cause the problem

2. It can be some timing problem with initialization. Try to play with some delays (just use Sleep(…)) inside constructor and FinalConstruct() method of your exe com server.

Regards,

To Retrieve Path of a DLL file.

Re: To Retrieve Path of a DLL file.

12-Feb-07 19:44

Hi all ,

How can I get the path of a COM DLL ??

I am using this way..

Inside DLL , I am writing this code.

/******************************************************/

HINSTANCE g_hInst;

TCHAR szModule[MAX_PATH];

g_hInst = _Module.GetModuleInstance();

GetModuleFileName(g_hInst, szModule, MAX_PATH);

/*******************************************************/

I am getting the Path . But am getting in this form..

"D:\THINVI~1\INTEGR~1.DLL" .

The tilt sign makes the folder and file names incomplete . My actual path is

"D:\THINVISITS_14-2-07\INTEGRALHOTBAR.DLL"

So how can I get my dll path in the complete form without Tilt(~)..

Please Help Me

Thanks
George.

Hi all,

I have a VB applicatiOn , which calls a function in VC++ DLL.

Arguement of function is a one dimensional string array.

Array will get filled in VC++ dll function.

I have written the programme given below.

But I am unable to get the array elements from VC++.

Programme is given below.

VC++ COM
/*****************************************/
STDMETHODIMP CTest111CL::myFun(SAFEARRAY **ppOutputArray)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())

HRESULT hresult;

SAFEARRAYBOUND aDim[1] ;

aDim[0].lLbound = 0;
aDim[0].cElements = 3;

BSTR HUGEP *pbstr;

*ppOutputArray = SafeArrayCreate(VT_BSTR , 1, aDim);

hresult=SafeArrayAccessData(*ppOutputArray,(void HUGEP**)&pbstr);

pbstr[0] = SysAllocString(OLESTR("SOURCE_VA"));
pbstr[1] = SysAllocString(OLESTR("ACV"));
pbstr[2] = SysAllocString(OLESTR("10"));

SafeArrayUnaccessData(*ppOutputArray);

return S_OK;
}
/**********************************************/

VB Application
---------------
''''''''''''''''''''''''''''
Dim i As Test111CL

Private Sub Command1_Click()

Dim arr_str(3) As String
Set i = New Test111CL
i.myFun arr_str()
MsgBox arr_str(1)
End Sub

''''''''''''''''''''''''''

MsgBox arr_str(1) , The message Box shows and empty string.

How can I rectify it. Please help me.

Thanks
George

Hello,

Try this:

Idl: HRESULT FunName([in,out] SAFEARRAY(BSTR)* pbsData);
.h: STDMETHOD(FunName)((SAFEARRAY** pbsData);
.cpp: STDMETHODIMP ClassName:: FunName(SAFEARRAY** pbsData)
{
//checking if it is an one-dimensional array
if((*pbsData)->cDims != 1)
return E_FAIL;

//Checking the number of elements of the array
if(3 != (*pbsData)->rgsabound[0].cElements)
return E_FAIL;

// locking the array before using its elements
HRESULT hr = SafeArrayLock(*pbsData);
if(FAILED(hr))
return E_FAIL;

// using the array
BSTR* pbs = (BSTR*)(*pbsData)->pvData;
pbs[0] = …
pbs[1] = …
pbs[2] = …
…
// releasing the array
return SafeArrayUnlock(*pbsData);
}

VB: Option Explicit
Option Base 1
Dim sArr(1 To 3) As String

Call ….FunName(sArr)

{
HRESULT hresult;
SAFEARRAYBOUND aDim[2]
aDim[0].lLbound = 0;
aDim[0].cElements = 3;

Change this to,

SAFEARRAYBOUND aDim[3] 
aDim[0].lLbound = 0; 
aDim[0].cElements = 3; 
aDim[1].lLbound = 0; 
aDim[1].cElements = 3

BSTR HUGEP *pbstr;

if (*ppOutputArray==NULL)

if (*ppOutputArray==NULL)
{
Messagebox("Null");
}
else
hr=SafeArrayAccessData(*ppOutputArray,(void HUGEP**)&pbstr

I think, you have messed up here.

This link will give you idea, how to use the array.
