Re: creating word document using c#

Hello All,

Is there anyway in which i can create a word document programmatically without using Office Interop or third-party libraries.

Yes - you can rewrite word, or if you want to only support the new version of Word, you can learn it's XML format and write something that uses that.

Just download Microsoft Office File Format :

And write your own code... Smile | :)

It's easier to use Office.Interop.

sysws.SaveWindowCompleted +=new SaveWindowCompletedEventHandler(sysws_SaveWindowCompleted);
sysws.SaveWindowAsync((SYSDataset)dsSystem.GetChanges());
}
catch (Exception ex)

throw (ex);
}
}

private void sysws_SaveWindowCompleted(object sender,
SaveWindowCompletedEventArgs e)
{
try
{
if (e.Error != null)
{
return;
}
this.dsSystem.AcceptChanges();

}
catch (Exception ex)

There are a number of errors in your post (please read the guidelines).

Your title is not acceptable - it is not urgent to anyone but yourself
Your posted code is not inside pre tag and is difficult to read.
You have not indicated where you get the error (what line)

You did describe the error so I can tell you there is an object that is declared but not initialised. Try debugging through the code to identify the line, look for an object that is 'null' where you expect it to have a value.

You can't. How do you expect to get progress notification from Word ?

If you're taking steps in your own code, you show a progress bar, as explained in a ton of articles.

Sure there is, there are many articles here on progress bars. However what CG was referring to is how are you going to define the progress of the open function. This is why there is a little circular animation used, you have no idea how long it will take.

how to disable close button of windows form

I really am at a loss. What have you tried, anything ? Showing a little busy icon while you open a document is so trivial, that I can't believe you've done anything beyond asking us to write it for you

Property ControlBox=false
Use event FormClosing and set e.Cancel=true.

OriginalGriff31-Aug-09 21:48

You can set

Form.ControlBox=false;

but this also removes the Min, Max, and system menu from the form as well.

To grey out the Close box, override the CreateParms getter:

protected override CreateParams CreateParams
    {
    get
        {
        CreateParams parms = base.CreateParams;
        parms.ClassStyle |= 0x200;  // CS_NOCLOSE
        return parms;
        }
    }

you can do it like this

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

but, you need to write methods such as 'MovingForm'or 'ResizeForm' or something else by yourself.
