thanks I'm at my first experiments with Parallel, applying the suggestions the loop is completed as long as I don't associate a control to another one.

limited the number of threads to 2

var options = new ParallelOptions()
{
MaxDegreeOfParallelism = 2
};

with association pnlCatalogo.Controls.Add(nDia[i]) , Cross-threading exception is guaranteed.

public void TestCornici(int i, Panel pnlImmagini)
{
numeroDia[i] = new Label();
pnlCatalogo.Controls.Add(numeroDia[i]); --> Cross-threading exception

.... without association
//pnlCatalogo.Controls.Add(numeroDia[i]); --> correct cycle
numeroDia[i].BorderStyle = BorderStyle.None;
.....
}

I limited the number of threads to 2

var options = new ParallelOptions()
{
MaxDegreeOfParallelism = 2
};

the cycle is executed correctly if I exclude: pnlCatalogo.Controls.Add(nDia[i])

nDia[i] = new Label();
//pnlCatalogo.Controls.Add(nDia[i]); --> exclude
nDia[i].BorderStyle = BorderStyle.None;
........

why the exception occurs associating a control (Label) to an other (Panel)?

just know the position of the cursor while dragging.
I am trying the solution by dragleave event

this routine solve then \n

string newLine = Environment.NewLine;
int at = 0;
string app;
string app1 = "";

while (s.Length > 0)
{
at = s.IndexOf("\n");
app = s.Substring(0, at) + newLine;
s = s.Substring(at + 1);
app1 = app1 + app;
}

textBox1.Text = app1;

now show
line1
line2
...
linex

ok, thanks; my error on row
this is correct.

DataTable dtFoto = new DataTable();
dtFoto = gesdb.QryRead(conn, dtFoto, Query); //execute query

MemoryStream ms;

int x = 0;
foreach (DataRow row in dtFoto.Rows)
{
FileImg = row["description"].ToString();

byte[] byteBLOBData = (Byte[])(row["public_note"]);
textBox1.Text = Encoding.UTF8.GetString(byteBLOBData);
}

then Blob is
line1
line2
...
the result is line1/nline2/nline3/n
texBox1 does not apply the /n
and show line1line2line3

I have installed connector 8.0.6 win32 (libeay32.dll)

inserted this file on
C:\Users _Test _Documents _Embarcadero _Studio _Projects _Win32 _Debug
and on
C:\Windows\System32

FDPhysMySQLDriverLink1.VendorLib
C:\Users _Maurizio _Documents _Embarcadero _Studio _Projects _Win32 _Debug _libeay32.dll

A Design Time doesn't work

At runtime, it all goes down.

FDPhysMySQLDriverLink1.VendorLib := ExtractFilePath(Application.ExeName) + 'libmysql.dll';
FDConnection1.Connected := true;

This solution is better than mine, I still can't move the focus from one item to the next.
I think we can simulate the click on ImageButton control

protected void Timer1_Tick(object sender, EventArgs e)
{
//simulate clck on ImageButton to enable event
}

I have modified and executed the code (for db MySql) of the link, but only responds to the click on an Item of the DataList.

better use c#

What you published yesterday does not need to understand which way to go or where the basic error is.

Member 13174280 24-Jan-18 4:36am View

it is clear that I am wrong, otherwise I would not have asked.
a minimal example would have been more constructive, to everyone's blessin
