how does using a CString += operator help me?  I'm trying to create a byte array.

<div>
had to change the szWrite to a BYTE array rather than a char array. &nbsp;but after that, it works like a charm.<br />
<br />
i knew it would something simple.<br />
<br />
thnx!

<div class="content wysiwyg-content">
I have a CString with hex values &quot;0122C24D&quot;. &nbsp;I need to create a byte array where each index of the array corresponds to each of the 2 respective hex characters in the CString.<br />
<br />
arr[0]=0x01<br />
arr[1]=0x22<br />
arr[2]=0xC2<br />
arr[3]=0x4D<br />
<br />
So far I have the code below, but blows up on the strcat_s.<br />
<br />
char *szMyString = NULL;<br />
char szWrite[512];<br />
CString cs = &quot;0122C24D&quot;, tmp;<br />
<br />
for(int i=0; i&lt;cs.GetLength(); i+=2)<br />
{<br />
&nbsp; &nbsp; tmp = cs.Mid(i,2);<br />
&nbsp; &nbsp; szMyString = (char*) (LPCTSTR) tmp;<br />
&nbsp; &nbsp; strcat_s(szWrite,512,szMyS<wbr />tring);<br />
}<br />
<br />
Any ideas?

CString w/ hex values &gt; byte array

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.

System Programming

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.
