Hi,
I need a code for printing a receipt in a WPF (C#) application using PrintDocument or another one else.
Thanks
|
|
|
|

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.

|

your code is totaly right but still some thig error is held in this code so please check it oncve again please

Uhhh...Just who do you think you're replying to?

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.

I have a web service and i send parameters date the it's give me exception string is not in good format my code is in v.b. and web service language is 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.

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?

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();
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.

Hi friends,
I am facing a problem in asp.net that i want to add a text box (it is a part of header of the page) in the head part of the master page without defining it into the form tag but when i run this on web page then it show the following error:
Exception Details: System.Web.HttpException: Control 'TextBox1' of type 'TextBox' must be placed inside a form tag with runat=server.
so how should i do.
|
|
|
|
|

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.

I am looking for a treeview control (C#) in which it accepts a Newick string as input and draw it but I did not find any thing.
Could anybody help me?

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.
