What part did you not understand?
Let's take the instructions one by one...
Quote: Create an empty text file somewhere on your hard disk, called "myfile.udl".
Have you done that?

The link gives teh next instruction:
Quote: Double click the file, and the "Data Link Properties" dialog will open:
Did you do that?
Do you get where I am going with this? Or do I need to copy and paste the whole Tip sentence by sentence as a separate reply to check you have done it?

Did you follow the instructions between "open the file" and "press the button"?
It's saying that the information you provided for that server / database is not valid: the login name, or password for example.
If you filled in the info from your existing connection string, then that's why that failed as well: you aren't authorised under that login.
We can't fix that, short of coming round to your place and typing on your keyboard - which would cost you a considerable amount of money in time, flights, hotels, taxis, expenses ...
So it's probably a good idea if you find out what your login info should be from the person who installed the DB!

Hello,
I am trying this example(and others), but i got the same error on every example. Of course even the error message says: object se.... i do not know why and neither the answer.
On every example i see: the error is always in the same definition.
i am using vs studio 2019
GDirections direccion;
var RutasDireccion = GMapProviders.GoogleMap.GetDirections(out direccion, inicio, final, false, false, false, false, false);
GMapRoute RutaObtenida = new GMapRoute(direccion.Route, "Ruta ubicación");
GMapOverlay CapaRutas = new GMapOverlay("Capa de la ruta");
CapaRutas.Routes.Add(RutaObtenida);
gMapa.Overlays.Add(CapaRutas);
gMapa.Zoom = gMapa.Zoom + 1;
gMapa.Zoom = gMapa.Zoom - 1;
contadorIndicadoresRuta = 0;
trazarRuta = false;
button3.Enabled = true;
break;

Hi,
I am using the TcpClient and I run Connect and then talk to a device on my network.. This works fine.
its something like 192.168.1.123. If my work VPN is connected.. Forticlient.. then the TCPClient Connect does not work. The VPN has a different network something like 10.230.x.x. So want to find out why this happens. If I disconnect the VPN it fixes.
The code is C# something like..
TcpClient client = new TcpClient();
client.Connect(ipaddress,port);
This creates an exception.. "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"..

This has nothing to do with your code. This is just how your VPN works.
When your corporate (I'm assuming) VPN starts up, for security reasons, you cannot have your network adapter sitting in both the 10.x and 192.168.x networks at the same time. Any traffic going through the network adapter is sent to the 10.x network.
You cannot bypass this.

Thanks that is handy to know.. so I will need to try to work out if the connection then is a VPN.. so I can inform the user that the tool will not work properly when connecting to the device.
More googling

Hi!
When i run my code with a excel document with words in, it works, but at fast as i read a document with numbers only i get error on marked line in code.
if (c.DataType.Value == CellValues.SharedString)
and the error is:
An error occurred!!!: The object reference has not been specified to an instance of an object.
I have a little hard to see why this happends, hope on you experts!
using (SpreadsheetDocument myDoc = SpreadsheetDocument.Open(input, true))
{
WorkbookPart workbookPart = myDoc.WorkbookPart;
WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();
SheetData sheetData = worksheetPart.Worksheet.Elements<SheetData>().First();
foreach (Row r in sheetData.Elements<Row>())
{
foreach (Cell c in r.Elements<Cell>())
{
string value = c.InnerText;
if (c.DataType.Value == CellValues.SharedString)
{
var stringTable = workbookPart.GetPartsOfType<SharedStringTablePart>()
.FirstOrDefault();
if (stringTable != null)
{
value = stringTable.SharedStringTable.ElementAt(int.Parse(value)).InnerText;
GenerateBarcodeFromExcel(value, output);
}
}
else
{
GenerateBarcodeFromExcel(c.CellValue.Text, output);
}
}
}
myDoc.Close();

Not all Cells are hard typed, only when you set the property on the cell explicitly.
Excel makes only strings SharedString by default.
So you need to check if the DataType property has been set, that is 'c.DataType != null'.

I want the MySQL 5.7.21 server to be installed from my application why the user downloaded it from the net. My application is ris.msi programmed in VS2015 with c #. The application is installed on the user's machine by clicking on ris.msi without any problems. During the installation of ris.msi I want to install MySQL Server 5.7.21 on the user machine. When I install ris.msi on my machine, everything works ok, but when ris.exe runs on the user's machine, the application cannot connect to the MySQL server. On my machine this works without problems, ris.msi is installed, I run ris.exe and I work with all the tables in the MySQL server, just like I do in VS2015.

Don't.
If you want a single user Db, use a single user DB: Access, SQLite, ...
If you want a multiuser DB, use a server based system: SQL Server or MySql
But don't install a multiuser DB unless you are going to have multiple users using it simultaneously.
There are a couple of reasons:
1) They may already have SQL Server / MySql installed on the network. If so, then they will presumably want to use that version.
2) If they do have a server installed and you start proliferating instances, you are going to annoy the heck out of the database administrator...
3) A single site installation of a server DB system is a lot more likely to be backed up than a number of scattered version under user control.
4) Server DB's are quite complex for a "normal" user to install and administer - it is not a good idea!
5) It will destroy the primary advantage of using a Server over SqlCE or SQLite - multiuser access. If everyone installs their own copy of SQL server, then you will have multiple copies of your database, each used by a single person. This will cause some confusion, and (depending on how you wrote the original database) may take some considerable effort to combine into a single instance when the problem is realized.

Ok, there doesn’t have to be more bases. This is a RIS.exe demo program that is located on only one computer, so it is necessary to install the MySQL database only on the computer where the program is. So the user can try out my program, which requires a MySQL database. It needs to be installed and then uses mysqld.exe. I am using MYSQL 5.7.21.0 and I developed the program in MS Visual Studio 2015. Thanks for the help.

I've set my own computer up with Apache/PHP/MySQL several times, and it has always required some manual configuring before everything was just right. I did that to learn, but there are several WAMP packages that install with everything configured automatically. If you don't know, WAMP is Apache, MySQL, and PHP in a package for Windows, thus WAMP.
Consider getting one of those packages and including it separately with your demo, and just instruct the clients to first install the WAMP and then install your demo.
As you move forward, consider adding more flexibility to your application so it doesn't have to have specifically a local MySQL database. Even if you stay with MySQL, the database should be able to be located anywhere, and all that needs to change is the connection string. Good luck!

We have some Syris (model RD200-M1) cardreaders with a USB cable.
It's a model where we put our company ID card on to read our company registration number.
I wonder if there is some code out there explaining how to read our card in C#.... ?
