Ah well..
yes, isFinished instead.. with a processEvent... checked (I take notes Very Happy

)

The rest Sad

This is just insane....

I tested with such loop:

for (int i = 0; i < grid.GetCount(); i++)
{
	grid.GetRow(i).Bg(LtGray());
	String item = grid(i,5);
	if (ToUpper(TrimBoth(item)).StartsWith("SHIPPING"))
	{
		continue; // skips the SQL query and i gets increased by the for loop
	}
	SQL * Select(SqlAll()).From(Whatever).Where(....);
	if(SQL.Fetch()){//some if then elses again }
}

And "inline" it works, it continues happily and leaves me with the correct iteration of i.

THIS however:

Thread().Run([=] {

for (int i = 0; i < grid.GetCount(); i++)
{
	grid.GetRow(i).Bg(LtGray());
	String item = grid(i,5);
	if (ToUpper(TrimBoth(item)).StartsWith("SHIPPING"))
	{
		continue; // will be ignored for some reason *SHRUGS*
	}
	SQL * Select(SqlAll()).From(Whatever).Where(....);
	if(SQL.Fetch()){//some if then elses again }
}

}

Just ignores the continue, sends an SQL query and as a result produces all kinds of errors
Worse:
correctly instead of a simple continue it holds a rowdelete

if (ToUpper(TrimBoth(item)).StartsWith("SHIPPING"))
{
	grid.Remove(i);
	i--;
	continue;
}

works just nicely

if (ToUpper(TrimBoth(item)).StartsWith("SHIPPING"))
{
	PostCallback([=] { grid.Remove(i); });
	i--;
	continue;
}

removes i-1 instead.
if there is i-1... if i was zero before I get Vcont.h line 84 Assertion Errors
of course (grid.Get(-1) crashes)
as if i is passed as a reference.

You see me completely baffled!

Ah well.. let's see if a while loop is more reliable inside the thread()...
Or do you have another idea?
