Recently I've been tasked with needing to add the ability to and existing VB6 application print to a certain type of printer:
http://global.dymo.com/enUS/Products/LabelWriter_400_Turbo.html
Now, I am aware that I would need the specific driver for this printer, but however I am curious if this particular printer requires anything different for me to actually add it's functionality to the application I'm supporting. This isn't time critical, so no one is in a hurry. So I'm posting this as I'm looking stuff up to help answer my question.
Thanks in advance.

No, not really. Windows abstracts printer functionality from your application. All you have to do is be able to handle smaller paper sizes properly.

Okay, thanks, I managed to find the SDK for the printer and I see how it works. It seems like I only need what I need to print, then run it through the proper subroutines on its way to the printer.

I suggest contacting the technical support of the maker of the printer for information like that.

I am using a Crystal Report file like this:
dim ds as new dataset
'filling dataset ...
dim myReport as new crystaldecisions.crystalreports.engine.reportdocument
myReport.load(application.startuppath & "\Report1.rpt")
myReport.setdatasource(ds.tables("Table1"))
'[...]
reportviewer1.reportsource = myReport
Depending on the user, I want one section of my report (one group's footer) to be seen or to be hidden.
When loading the report the described way, how do I get a grip on a certain section or object in myReport in runtime to change some of its properties?

The easiest way would probably be to have your report set up to accept a parameter. Then in the report file it would suppress a section or display it based on that parameters value. I would suggest that you research crystal report parameters [^]for more details as to how that is done.
I hope this helps.

Thanks for the hint. I did what you suggested: I added a boolean parameterfield to my report to which I pass true or false from runtime. Depending on this parameterfield the section is suppressed or shown.
Thanks.

Hello everyone,
I am new to this forum, and to posting in code forums in general, so i hope i have this in the right place, and i apologize if i don't.
I wrote a VB program that has a function that passes in the date (as an integer such as 28032008) and determines the name of the month (such as March) or the weekday (such as Friday). On my laptop it works great.
Then i tried putting it on another computer and i got the error message:
Conversion from string "28 03 2008" to date is invalid.
At first i thought it might need a .NET update, and after installing all of those, i still had the problem.
And then i realized what was happening - My computer displays the date (today) as 07/04/2008, but on the other computer it is shown as 04/07/2008, so my program and that computer are mixing up the day with the month.
Anyone have an idea how to detect the date format of the local computer so i can have my program adjust accordingly?
Thanks for reading,
Nicholas

Hi,
you can create a DateTime with known Day/Month/Year (see the constructors) and have it
converted to string in the system's default format (ToString methid), then you can "look"
at the string.
But you probably don't need all this; you can ask the DateTime type to parse a string
according to the system's settings, so it should work for you automatically as long as
the user follows his system's settings.
Of course, you can also override the date format, both in ToString() and in Parse() or TryParse().

You are making one of the standard errors nearly all programmers make when starting out, treating date data as a string. ALWAYS store your date data as a date data type NOT a string. If you do this it eliminates this (and quite a few other) issues.
If you must store your date as a string format the string as "dd/MMM/yyyy" this will remove any ambiguity caused by the format and you can reliably convert it into a date data type.
Never underestimate the power of human stupidity

I am dealing with a database that stores the date in an integer format. I was only converting that to string in order to separate the month, day and year portions, and then attempting to convert it to date to get the month name or the weekday.
Thank you both for the replies.

This requires writing a Browser Helper Object.
Member 4080684 wrote: in asp.net
This cannot be done using ASP.NET. ASP.NET code runs service-side only. What you're looking for, a copy of the Google search component, cannot be written using ASP.NET.

The only thing urgent in a forum environment is the need to finish your post before you have to pee.

I don't believe that you can, but if you can, then reading the article I link to in my sig would be the right first step to take here.
I suspect you need to use C++ to write an add in for IE, but I could be wrong. I know you'll need to write one for IE and one for FireFox, seperately.

Like Christian said, Google is your first stop. Search for "VB.NET Browser Helper Object" to get started.

First step is to understand what you're asking. ASP.NET cannot do that, why would you need to do it using a technology that doesn't do what you want ?

Add a column to your datatable
dtProducts.Columns.Add("Total", typeof(System.Int32))
then add an expression to that column
dtProducts.Columns[index].Expression("unitsinstock * unitpricefield")
Good luck

can i know what use of (system.int32)
and dtproduct do i need to declare the "dt" like
is it do like below...
private btncalculate_click(.....)<br />
dim dtproduct as new stocktableadapter<br />
dtProducts.Columns.Add("Total", typeof(System.Int32))<br />
<br />
dtProducts.Columns[index].Expression("unitsinstock * unitpricefield")
thanks for the idea
it good if any can give me full coding..because i'm quite weak i do i declare all the "index",dtproduct,and what is system.int32
thing that i want to count is when click on combo box...it show hardware name and datagridview that will show the price list.then i need count unitprice in vb.net..ouantity is i enter myself.so unitprice*oty=total

I have a MenuStrip on form on which options are added at runtime.
I am handling the MouseHover event, which fires as expected.
Private Sub systemMenuStrip_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles systemMenuStrip.MouseHover<br />
Dim oCursorPosition As System.Drawing.Point = Cursor.Position<br />
Dim oMenu As System.Windows.Forms.MenuStrip = DirectCast(sender, System.Windows.Forms.MenuStrip)<br />
Dim oOption As System.Windows.Forms.ToolStripItem = oMenu.GetItemAt(oCursorPosition)<br />
End Sub
The problem I am experiencing is obtain the option that I am currently hovering over. The value of oOption is always Nothing.
Any help appreciated, as always

Hi,
seems to me Cursor.Position is returning an absolute (i.e. screen related) position,
whereas GetItemAt is likely to work with relative coordinates.

If you want to know when mouse is over a menu strip item, you may directly add a MouseHover event for ToolStripMenu items.
This will allow you to execute a piece of code when mouse is over any particular menu strip item.
Such as –
---------------
Private Sub FileToolStripMenuItem_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles FileToolStripMenuItem.MouseHover
MsgBox("Over File Menu")
End Sub
---------------
I hope this helps.

Not 100% sure, but I think you need to look at the Windows Management Interface (WMI)
see the System.Management namespace
