dunno if this helps, but you can define a fixed length string with<br />
dim strxxx as string * 500<br />
<br />
You can access any character in it by using<br />
<br />
strxxy=mid(strxxx,position<wbr />,1)<br />
<br />
<br />

</div>

You can use RtlMoveMemory API to copy a struct into a buffer &nbsp;directly, I think that will be the furthermost vb can do <br />
Anyway, why are you asking, there might be a better way to achive what you want<br />

Is there anyway in VB that you can define a String of Data (Buffer) and reference that data using a structure (Type) with a pointer?<br />
<br />
VC Example:<br />
<br />
struct EntryStruct<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;char szFldName [50]; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;int &nbsp;nFldNumber;<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;};<br />
<br />
<br />
char szBuffer [500];<br />
char szName &nbsp; [100]; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
<br />
EntryStruct* pPtr;<br />
pPtr = (EntryStruct*) szBuffer;<br />
szName = pPtr.szFldName;<br />

How to use VC structures and pointers in VB

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
