You can use boolean, for example

plugin constructor{

isHidden=true;
control->Hide(true);
}

void MyTest::OnParamChange(int paramIdx)
{
switch (paramIdx)
{
case kGain:
mGain = GetParam(paramIdx)->Value() / 100.;
if (mGain<=0)
{
control->Hide(false);
isHidden=false;
} else if(!isHidden)
{
control->Hide(true);
isHidden=true;
}
break;

As it seems to me, I found a more correct solution. As noted in another thread, the problem is that mLayoutFunc is called later than other functions,
therefore IControl objects are not initialized. I tried to initialize them before mLayoutFunc, and in mLayoutFunc only use AttachControl. Everything works fine.
