Converts a lump of binary/text data to hex format.

Introduction

This is a simple COM component that converts a lump of binary/text data to the hex format. I just wrote it for one of my projects to have a look at the binary data. The component supports only two interfaces; IHexConverter and ISupportErrorInfo, with four methods. It's been developed on Win98, with VC++ 6.0. It's very simple in use, and I thought it might be useful for others.

Methods

SetFile([in] BSTR bstrFilePath);
SetString([in] BSTR bstrInput);
GetLineCount([out] long* pLineCount)
GetNextLine([out] BSTR* pbstrOutput)

Typical Usage (in C++):

::CoInitialize(NULL);

IHexConvertor* pHC = NULL;
HRESULT hr = CoCreateInstance(CLSID_HexConverter,
                             CLSTX_INPROC_SERVER,
                             IID_IHexConverter,
                             (void**)&pHC);

//Set the input file / string
CComBSTR bstrFile(_T("C:\MyFile.dat"))
hr = pHC->SetFile(bstrFile);

or

CComBSTR bstrInput(_T("blah........blah............"));
hr = pHC->SetString(bstrString);

//get the total no. of lines in the output string (containing 16 bytes each)
long lLines;
hr = pHC->GetLineCount(&iLines);

//get each line
for(int i = 0; i < iLines; i++)
{
    CComBSTR bstrOutput;
    hr = pHC->GetNextLine(&bstrOutput);
}

pHC->Release();
pHC = NULL;

::CoUnInitialize();

You need to register the component before use. If you spot any problems or possible enhancements please let me know at <a href="mailto:mukesh_ind@hotmail.com">[Mukesh Gupta].
