Try:<br />
Dim Str as String = &quot;something&quot;<br />
If you pass Nothing as a reference, your method might have trouble with it.

But you are not getting the string itself, rather you are getting the pointer. &nbsp;You need to retrieve the string value from the memory location that the pointer references. &nbsp;For that, .NET has some ready made helper methods in the <a href="https://msdn.microsoft.com/en-us/library/system.runtime.interopservices(v=vs.110).aspx" rel="ugc">System.Runtime.InteropServ<wbr />ices</a> namespace. &nbsp;The one that is of benefit to you is <a href="https://msdn.microsoft.com/en-us/library/system.runtime.interopservices.marshal.ptrtostringbstr(v=vs.110).aspx" rel="ugc">Marshal.PtrToStringBSTR(In<wbr />tPtr)</a>.<br />

Hello Everyone,<br />
<br />
I am getting the following issue:<br />
Cannot retrieve a bstr* via com interface into a system.string in vb.net<br />
<br />
I tryed to use StringBuilder but then I get a compilation error.<br />
I also did: &nbsp;<br />
<br />
Dim Str as String = nothing<br />
<br />
myobj.getMessage(Str)<br />
--&gt; result: nothing <br />
<br />
Is there an equivalent like in c# using [ref] - &gt;&nbsp;myobj.getMessage(ref Str); &nbsp;where this works as expected.<br />
<br />
All inputs are welcome.<br />
Thank you very much in advance.<br />
Best regards<br />

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,
