Hi,<br />
I need to add multiple bstr strings using C++, I am aware to add bstr we can:<br />
<br />
int lenBuffer;<br />
BSTR bstr1,bstr2, bstr3,;<br />
//assign some values to bstr's<br />
lenBuffer = SysStringLen(bstr1) + SysStringLen(bstr2) + SysStringLen(bstr3);<br />
BSTR bstrQuery;<br />
bstrQuery = SysAllocStringLen(L&quot;&quot;,lenB<wbr />uffer+1);<br />
wcscat_s(bstrQuery,lenBuff<wbr />er+1,bstr1<wbr />);<br />
wcscat_s(bstrQuery,lenBuff<wbr />er+1,bstr2<wbr />);<br />
wcscat_s(bstrQuery,lenBuff<wbr />er+1,bstr3<wbr />);<br />
<br />
is there any better way of doing it, I have around 6 bstr strings(or more) to concatenate, whats the best possible way of doing it?<br />
<br />
TIA<br />
<br />

Hi,
I need to add multiple bstr strings using C++, I am aware to add bstr we can:

lenBuffer = SysStringLen(bstr1) + SysStringLen(bstr2) + SysStringLen(bstr3);
BSTR bstrQuery;
bstrQuery = SysAllocStringLen(L"",lenBuffer+1);
wcscat_s(bstrQuery,lenBuffer+1,bstr1);
wcscat_s(bstrQuery,lenBuffer+1,bstr2);
wcscat_s(bstrQuery,lenBuffer+1,bstr3);

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
