You have already posted this question in the .NET Framework forum[^].

Posting the same question in multiple forums on the same site is only going to annoy the people who would otherwise be trying to help you.

OK. The only code you're going to get is the code that YOU write yourself.

Nobody here is going to do it for you and just Googling around for "print a receipt from a WPF app" is going to get you some vague code samples that you're going to have to adapt anyway.

Another way is:

1. Create RDLC or Report File for as per your print document requirement.
2. Assign DataSet to you report file.
3. Create PDF file in specified location.
4. Using Browser control you can show it in pdf viewer in you apps.
5. And Generate print from pdf viewer.

How to convert Date of v.b to DateTime of c#

At a guess, it's a string - or you wouldn't be converting it. Which implies the service computer and the application computer are using different locales, or cultures.

Don't - pass it as a date value: always keep values in the most sensible datatype, rather than strings...

No web service is web service. It might be implemented in C# but that doesn't change anything.

Djay Hole wrote:

The web service expects a web service call with the data in the format that it expects. And you are not sending it that way. Figure out the correct format and send it that way.

Look into the DateTime ToString[^] method and the DateTime TryParseExact[^] methods.

Although you could just pass the Date or DateTime objects as is? Chances are it is compatible. But for the record, I'm assuming you're talking VB.Net?

Delete file which was in Picture Box before loading another Picture

I have picturebox and i trying write code when the users loads another image on picturebox the old file which was in picture to be deleted. I trying to find solution for for 24 hrs still i didn't able find fully working solution.

I came up with 1 partial solution and following is partial code

profilePictureBox.Dispose(); // When I use This After The Function Executed
                                 PictureBox Disappears But File Delete Successfully.
 try
                {
                    if (File.Exists(oldfilename))
                    {
                        File.Delete(oldfilename);
                        profilePicPictureBox.Load(picPath);
                    }
                    else
                    {
                        MessageBox.Show("File Not Found");
                    }
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.ToString());
                }

"old filename" will contain previous filename to delete and "picPath" will contains new path of image user chosen.

and also when tried method like

profilePictureBox.Image = null;
i am getting below error

System.IO.IOExecption:The Process cannot access the file 
'filepath' because it is being      used by another process.

Your picture box is referencing the file on the hard disk, you need to set the content of the picturebox to null BEFORE attempting to delete the file. OR load the new file into the picturebox (releasing the old file) and then delete the old file.

Never underestimate the power of human stupidity

The error message is pretty clear: every TextBox control must be within a <form runat="server">...</form> tag. You cannot have a TextBox outside of the form tag.

A text box is supposed to be in the form tag itself. Why do you want it to be in outside of the form tag .

So much complexity in software comes from trying to make one thing do two things.

We don't write new tree-controls for each format out there. You would have to write an adapter that transforms your data to what a normal treeview expects.
