Well there are 2 Down votes now but at least I know why now and that's all I was asking.
And I will report the bug.
Thank you for your time.

In my app I have the ability for users to attach files. These files can be anything such as Word documents, PDFs, images, Excel spreadsheets, etc. Is there a way to give the users the ability to print these files by clicking a single button? I was thinking that when you are in Windows Explorer and right click on a file one of the options is to print the selected file so there must be a way to call that type of functionality from code.

Assuming it's a desktop application, you can print a file by using Process.Start[^] with the "print" verb.
Dim psi As New ProcessStartInfo
psi.FileName = pathToTheFile
psi.Verb = "print"
Process.Start(psi)
NB: This requires that there is an application registered to print the file. Any file which shows "print" in the Windows Explorer context menu should work.

This is a report program, in which I have to match filters to get a list of items.
So overall I'm missing some data that I need to find and see what it is.
I have this filter called states, in which the invoice shipping item has to match a state selected
For Each state As String In p.States
gInvoices_raw.AddRange(gInvoices_all.Where(Function(m) m.FSSTATE = state))
Next
In the loop, I need to find out what is left over, what remains, so I thought I would RemoveRange from gInvoices_all
But I don't have the slighest clue how to get the start and stop index of the Range to remove here
Or perhaps there is a better solution here.
gInvoices_all = gInvoices_all.OrderBy(Function(m) m.FSSTATE).ToList()
For Each state As String In p.States
gInvoices_raw.AddRange(gInvoices_all.Where(Function(m) m.FSSTATE = state))
gInvoices_all.RemoveRange(xxxxxxxxxxxxxxxxxxxxxxx)
Next
If it ain't broke don't fix it

Maybe I should just run this for now while I'm looking for missing sales
For Each state As String In p.States
Dim filteredInvoices As List(Of model_itemDistribution_Invoices) = gInvoices_all.Where(Function(m) m.FSSTATE = state).OrderBy(Function(m) m.FSHIPDATE).ToList()
gInvoices_raw.AddRange(filteredInvoices)
'Remove the Invoices just seleted from gInvoices_all
For Each invoice In filteredInvoices
gInvoices_all.Remove(invoice)
Next
Next
If it ain't broke don't fix it

Try:
gInvoices_raw.AddRange(gInvoices_all.Where(Function(m) m.FSSTATE = state))
gInvoices_all.RemoveAll(Function(m) m.FSSTATE = state)

So I have this list of customer invoices that I need to just group into a list of
Customers
Customers by State,
Customers by City, or Street Address if there are multiple locations in a city
But on a small check, I got a duplicate, 2 customers in Tempe AZ with the same street address.
I did something wrong here but not sure what.
'Group all the Customers together from gInvoices_all
Dim gCustomers As List(Of model_itemDistribution_Invoices) = gInvoices_all.OrderBy(Function(ob) ob.FCUSTNO).GroupBy(Function(v) New With {Key v.FCUSTNO, Key v.FSSTATE, Key v.FSADDR1}).Select(Function(cl) New model_itemDistribution_Invoices() With {
.FCUSTNO = cl.First().FCUSTNO,
.FSSTATE = cl.First().FSSTATE,
.FSADDR1 = cl.First().FSADDR1,
.FCOMPANY = cl.First().FCOMPANY,
.FSALESPN = cl.First().FSALESPN,
.FCONTACT = cl.First().FCONTACT,
.FPHONE = cl.First().FPHONE,
.FSADDR2 = cl.First().FSADDR2,
.FSCITY = cl.First().FSCITY,
.FSZIPCODE = cl.First().FSZIPCODE,
.FSCOUNTRY = cl.First().FSCOUNTRY,
.FCSAMT = 0.0
}).ToList()

At least one of the three columns you're grouping by will be different. Check for leading/trailing white-space, and if you're querying an in-memory collection, check the case of the values too.

I'll do a trim, startswith or contains and see what happens

Do these two customers have the same FCUSTNO, or different ones? I'd assume that the street address is not the primary key, or even a unique value.

The duplicate has the same FCUSTNO, Same FSTATE, duplicate is the FADDR1
For now I ran the GroupBy twice and got a completly different result, less records but it looks correct.

I've tried so many approaches... a simple "one-tier" JSON structure us easy, but when it comes to more complex objects, I cannot figure this out, despite help from various articles here and elsewhere (thought here aren't that many I've found.)
A typical structure I need to parse is like this:
{
"odata.metadata" : "blahblah",
"value" : [
{
"prop1" : 69,
"prop2" : 96,
"prop3" : "Blah",
"prop4" : "Blah",
"prop5" : [
{
"sub1" : 269,
"sub2" : 3,
"sub3" : "something",
"sub4" : null
}
],
"prop6" : []
},
{
"prop1" : 23,
"prop2" : 45,
"prop3" : "Blah2",
"prop4" : null,
"prop5" : [],
"prop6" : [
{
"sub1" : 169,
"sub2" : 7,
"sub3" : null,
"sub4" : "2017-10-01"
}
]
}
],
"odata.nextLink" : "blahblahURL"
}
They all have the same three top-level elements: "odata.metadata", "odata.nextLink" and "value", and it is only the "value" element that may differ - some will have more or fewer properties, but typically as above.
I start by defining a class:
Friend MustInherit Class Response
<JsonProperty("odata.metadata")>
Public MetaData As String
<JsonProperty("odata.nextLink")>
Public NextLink As String
End Class
Friend Class ClsTest
Inherits Response
<JsonProperty("value")>
Public Property TESTS() As Linq.JArray
End Class
I keep ClsTest separate as I may want to have different ones for different JSON structures, depending on what the final approach is....
then I can deserialize it in two different ways - if "json" is the string representing the object above:
1. using the class:
Dim cls As clsTest = JsonConvert.DeserializeObject(Of clsTest)(json)
2. or using a JObject
Dim jsonObject As Linq.JObject = JsonConvert.DeserializeObject(json)
but after each I can't get beyond extracting the "odata" values - I can't figure out how to get the "values" and read them into something I can work with in my application: - classes, lists arrays, whatever...
I realise this is still a rather general question and maybe not specific enough, but really any hints or help will be appreciated...

In my current (Windows Forms Application) project, I have a form which includes a number of DataGridViews, which are used to display tabular data for the user to look at and edit. The data sets are of known, fixed, size, and the DGVs are designed to allow the data sets to fit neatly within them. The ability to scroll the view (in any direction) is neither wanted nor needed.
I have disabled the scroll bars and set AllowUserToAddRows to false, but navigating down with the arrow keys still causes a blank row to appear at the bottom and the top row of data to disappear; arrowing all the way up reverses this. One odd aspect of this is that the scrolling up happens when you arrow down from the last but one to the last real row. If you use the mouse to select a cell in the last row and then try to arrow down, nothing happens.
There is what appears to be a fair amount of discussion of this problem in various places, but the solution generally given is to disable the scroll bars and set AllowUserToAddRows to false, which doesn't seem to work for me. I have also tried capturing the Scroll Event and repositioning the Selected Cell to the top of the DGV within it, which sort of works, but this has other unwanted side-effects. Has anyone else run into this problem and/or come up with a good solution?

After spending a lot of time researching this, I was able to come up with a solution which works, but there should be an easier way! There are a lot of 'gotchas', apparently 'baked in' to the design of the control. Not only does the view scroll up (by default) when you arrow down into a cell in the last row, but it also scrolls up if you arrow left or right while in the last row.
Implementing my solution involves a number of steps:
1) Subclass the DataGridView control so that you can (optionally) override its ProcessCmdKey method to disable special handling of the arrow keys (you don't actually need to mess with the up arrow key, but I found it easier to disable all of them.
2) Substitute references to your new MyDataGridView control for those to the original version in the containing Form's Designer.vb file - for me, using VS 2013, two references needed to be changed for each affected control. Then, either in the designer or in initialization code, set the option to disable the arrow keys for the modified controls.
3) Write code for the KeyUp and KeyDown Events for each affected control - the KeyDown code does apparently need to be there, but it only has to set the Handled event argument to True; the KeyUp code has to do the work of changing the current cell appropriately for the arrow key pressed. For any arrow keystroke that results in a move to a cell in the bottom row (including a lateral one), the KeyUp code also has to set the control's FirstDisplayedScrollingRowIndex Property to 0 after implementing the move. This is what scrolls the view back down again to abolish the empty row, but it does cause a visible 'glitch'.
4) If you don't want the view to appear to 'glitch' when the user is moving to or on the bottom row, it is best to surround the working KeyUp code with calls to disable and re-enable screen painting while it is (in effect) moving the focus about.

Hello,
how can I change the fomat from the
Worksheets(Db).Cells(uGeraet, 1).Value to add it to the sheetname.
Whole code sample:
Sheets.Add
ActiveSheet.Name = "Example" & Worksheets(Db).Cells(uGeraet, 1).Value
Thanks

We still do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, you may find it is not as difficult as you think!
If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

That is called research and this is the wrong place to do that research. You need to search for the existing software and papers on that software design in the subject you are supposed to be learning about.
Once you have found the details you need and if you have trouble with the coding then feel free to ask those questions here.
