Re: Print Dialog and printing current page

18-Mar-08 23:23

how do i use the print dialog to print the current page. I'm guessing upon return from the print dialog i can check a property which will tell me if "current page" is clicked. but i cant find it for the life of me. barking up the wrong tree?

cheers

if (this.printDialogReport.PrinterSettings.PrintRange == System.Drawing.Printing.PrintRange.CurrentPage)<br />
{<br />
...<br />
}

Listview.Contains problem..

this[^] would have been quicker for you.

If you subtract one date from another, you get a TimeSpan

as in

TimeSpan ts = date2 - date1;

Use DateTime.CompareTo to determine which of your dates is earliest, then substract it from the other using DateTime.Substract to determine the timespan you need.

Standards are great! Everybody should have one!

string[] stringArray = {"Hello", "World"};<br />
ListViewItem lvi = new ListViewItem(StringArray);<br />
<br />
if(this.listview1.items.contains(lvi))<br />
{<br />
   ;//do nothing<br />
}<br />
else<br />
{<br />
    this.listview1.items.add(lvi);<br />
    this.listview1.update();<br />
}<br />

Why does this code always run in else block when the same Listview item is added into the listview??

Is it because everytime a new object is created??
What if I want to compare listview items and then add into listviews???`

Because it doesn't. Even if the contents of the two items are the same, they are two different list view items. They just happen to have the same strings in them. You need to search through the strings inside the items, if that is what you mean.

Do u mean to say I need to use the 'SubItem' property..??
Then how do we use listview.contains ?

I'm assuming there's a find method which finds the first item which contains a string, or something like that.

Well actually I found out something better:

ListView.FindItemWithText

What happens if you create a method on the mdi-parent that opens the edit form? By using this technique the two forms are opened the same way. If you still get the same behavior the problem must be related to how you have set up the two forms.

Well, you need to start experimenting to find the source of the error. Then you can judge if you should try to solve it or try to find another acceptable solution. Just sitting there waiting for answers will get you nowhere.

Another thing you can try is to comment out the line where you set FormBorderStyle.

i agree with this.

create your midi forms on the midi parent... always.

if you want to create/call from another midi child, create an event on the midi child, something like "CreateMidiChild", and when the event is triggered the midi parent which will be subscribed to this event can create the new child for you.

What on earth is your question ? What do you mean by service pack ? What do you mean by 'not running' ? Is this even a C# question ?

OK, first of all, when you build an exe, it's NOT called a service pack.

Second, if it doesn't run in vista, you need to work out at what point it fails, and then you can work out why.
