Problem With Checking Print Result Follow
Hello.
I have problem with checking print result.
Code:
if (labelFormat.Print("Label for " + txtPN.Text, out mess) == Seagull.BarTender.Print.Result.Success) { // Save last serial number to DB } else { MessageBox.Show("Not printed"); }
(labelFormat is defined as: Seagull.BarTender.Print.LabelFormatDocument labelFormat = btEngine.Documents.Open(file); )
Problem: The label is printed sucessfully but MessageBox is showed.
How to properly check whether the label is successfully printed?
I'm sorry for my bad english...

Maybe you'd want to specify a time out. Also try fault finding things by seeing what messages are returned by the print request. See the below example from the BarTender Help system:
public void Demo() { // Initialize a new BarTender print engine. using (Engine btEngine = new Engine()) { // Start the BarTender print engine. btEngine.Start(); // Open a format document. LabelFormatDocument btFormat = btEngine.Documents.Open(@"C:\Format1.btw"); // Print the format document specifying the job name, // and get any messages returned. Messages btMessages = null; Result nResult = btFormat.Print("Test Print", out btMessages); // Display the print result. Console.WriteLine("Print status = " + nResult); // Print all returned messages. foreach (Message m in btMessages) { Console.WriteLine("Category = " + m.Category); Console.WriteLine("ID = " + m.ID); Console.WriteLine("Severity = " + m.Severity); Console.WriteLine("Text = " + m.Text); Console.WriteLine(" "); } // Close the current format without saving. btFormat.Close(SaveOptions.DoNotSaveChanges); // Stop the BarTender print engine. btEngine.Stop(); } }
Thank you for your answer.
When I use this:
ress = labelFormat.Print("Label for " + txtPN.Text, out mess) if(ress != Result.Success) { // error } else { // Save data to DB }
All is OK and data are saved in DB.
What is the difference between this?
if(labelFormat.Print("Label for " + txtPN.Text, out mess) != Result.Success) { // error } else { // Save data to DB }
This throws error (but label is printed), why? It's the same.
