According to the MSDN documentation for CONSOLE_CURSOR_INFO, the dwSize member must be between 1 and 100 (apparently inclusive). Try setting it to 1 instead of 0. :)

I tried it after fixing the bad param and sure the cursor did disappear.

<div class="content wysiwyg-content">
I am trying to code a HideCursor() function.Iread the MSDN i thought <br />
I knew what to do ..but it turns out my function does not work.<br />
<br />
This is how i implemented it.<br />
<br />
void System::HideCursor(void)<br />
{<br />
&nbsp; &nbsp; &nbsp;HANDLE Console = GetStdHandle(STD_OUTPUT_HA<wbr />NDLE);<br />
&nbsp; &nbsp; &nbsp;CONSOLE_CURSOR_INFO &nbsp; CursorInfo;<br />
&nbsp; &nbsp; &nbsp;char buffer[10]={0};<br />
&nbsp; &nbsp; &nbsp;CursorInfo.bVisible=false;<wbr /><br />
&nbsp; &nbsp; &nbsp;CursorInfo.dwSize=0;<br />
&nbsp; &nbsp; &nbsp;SetConsoleCursorInfo(Conso<wbr />le,&amp;Cursor<wbr />Info); // HERE OCCURS THE ERROR, THE FUNCTION FAILS<br />
&nbsp; &nbsp; &nbsp;<br />
}<br />
<br />
But it does absolutely nothing.Do not waste time dubugging.<br />
I traced the error and it seems to be System Error 87 : The Parameter is Incorect.<br />
<br />
Now why is this happening.I even tried the more radical solution<br />
...that is using a CONSOLE_CURSOR_INFO *CursorInfo. The function failed in that case too.<br />
<br />
Please help me find a solution.Thank you!<br />
<br />
Somehow, the printf() and cout&lt;&lt; functions don't appear to work in this environment.anybody have an <br />
idea on this?

Windows Console Programming Problem

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.
