<div class="markdown_content"><p>Thanks for your reply!</p> <p>Unfortunately it didn't work. The dereferenced pointer to the string stays empty. Please look at the attached picture.</p> <p>Do you have any more ideas? Who would know this?</p> <p><img alt="IMG: Clipboard01.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=186"/></p></div>

<div class="markdown_content"><p>Goodmorning all,</p> <p>Here's the question:</p> <p>From the library: SysLibTargetVisu_v10.lib I use the following function to get translations from a dynamic text list.</p> <div class="codehilite"><pre><span></span><span class="n">GetText</span><span class="p">(</span><span class="n">stResult</span><span class="p">,</span> <span class="n">nResultLength</span><span class="p">,</span> <span class="n">stPrefix</span><span class="p">,</span> <span class="n">dwID</span><span class="p">)</span> </pre></div> <p>This works perfectly. The string variable stResult now has the correct translation. <br/> However, now we have a Russian customer so I have to load Cyrillic characters (unicode).<br/> I will have to use the following function:</p> <div class="codehilite"><pre><span></span><span class="n">GetUnicodeText</span><span class="p">(</span><span class="n">pResult</span><span class="p">,</span> <span class="n">nResultLength</span><span class="p">,</span> <span class="n">stPrefix</span><span class="p">,</span> <span class="n">dwID</span><span class="p">)</span> </pre></div> <p>As you can see this function does not return a string, but a pointer instead. the variable pResult is of the type: POINTER TO ARRAY <span>[0..10000]</span> OF UINT.</p> <p>Does someone have an idea how to use this pointer? How do I generate a string from this array of UINT?</p> <p>Help would be much appreciated </p> <p>Thanks,</p> <p>Stefan</p></div>
