The problem is that Tab is both an acceptable character in your editing control and a control key in the DGV. It may be as simple as excluding the Tab from your editing control (OnKeyDown filter,...

All the looping is taking the time away, especially the double loops. A lot of these changes can be made with a single command by using the columns as the basic unit rather than the cell, eg.

They could? 100329 Can't say I've ever seen one there.

Perhaps you should elucidate for us exactly what value(s) you are attempting to obtain here. As it stands it looks to be almost entirely arbitrary.

Well normally yes, but surely the whole point of the custom editing control is to make it impossible to enter invalid data in the first place? The 15 digit maximum (or at least a MaximumDigits...

Actually if you use the correct operator, &, then the conversion is inferred and the explicit conversion is unnecessary, so the error wouldn't ever have arisen.

Also think about the logic of your conditionals. All of them require that TextBox1.Text <> Nothing (that should actually be <> "", by the way) so you can make that the first step (not only more...

You're really never going to pin this down with absolute accuracy. Point conversion (to screen, to client) is simply not reliable enough especially when working with both client and screen...

Dammit! When did 'I'm a newbie' become an excuse for not exercising the simplest of study skills like reading? You give people a one page text to scan for a specific piece of information and it's...

Well firstly, all of the methods will be useful at some time so it wouldn't hurt to learn and practice with them. Secondly I suggested If split(i) starts with "z". Really shouldn't be that difficult...

So, to save typing in the container number and pressing a button on the website you want to type in the container number and press a button in your program?

Try the Codebank thread on manipulating...

Correct. However you can pass their values. So you could, for example declare ...

Public Function ConferenceTotal1(ByVal RChecked As Boolean) As Decimal
If RChecked Then
etc.

... and when...

Yup. Null means there is absolutely no value of any kind present. You can't convert nothing to anything. To avoid this problem you should set a default value rather than allowing Null.

Why would you want to prevent moving to another cell? Your users will press Tab or Enter specifically to do that very thing.

I really don't understand what you mean. It seems to work perfectly. In Numbers mode only numbers are permitted so surely all the validation events are taking place as expected?

Well let's see. It's difficult (near impossible for anyone with eyes as old as mine!) to read the code and impossible to copy it. In this case the only code we get to see is actually the least...

I think you can take that as a fairly explicit statement of company policy. It would certainly be taken to be so by any court! If you can't do it then it's reasonable to assume that you shouldn't!

What exactly constitutes much slower? I can't say I've ever encountered any performance problems with the DGV itself so it's much more likely that any problems are in what you're doing with it and...

It almost certainly is possible but as you would be explicitly aiding someone in breaking company policy (if not the law) with the likely result that said someone could be dismissed or worse don't...

It's got nothing to do with the tab control. You haven't added a webbrowser control to the new tab so it's not surprising that telling the non-existent control to navigate results in an error. As...

The exact wording of the warning would help in determining this.

Load the judges scores into an array. Sort the array then use only values 1 - 6 (0 and 7 being automatically the top and bottom).

Values in selectable controls will automatically 'reset' when a...

It kinda depends on how ready you are for something a little bit more complex but it looks to me that your best bet would be either to create a DayStats class which would have properties for each of...

You'd handle the key down event, and delete the selected item.

In what way is that obvious? Nothing in your code or your description suggests that at all. You seem(ed) to be unaware that a list in VB.Net is not a list in the sense which we normally use it. The...

Well there's your problem! You could run a country with that much software but not on a standard PC system! I'm frankly surprised the only evidence of the problem is this!

ListBox1.DataSource = dt
ListBox1.Items.LoadFromFile("Names.txt")

It has to be one or the other. It can't be both. The binding will take precedence.

Hmm. You are prevented from doing what, if it isn't flat out illegal, is certainly morally questionable. I can live with that!

Use the My.Computer.FileSystem.MoveDirectory method instead. The overloads include automatic overwriting of existing files and/or showing the Windows dialogs which allow you to choose actions.

That's assuming that you gave the label a name in the first place, of course. You'd be amazed how many people forget!

No. The prediction is that the Gulf Stream will be diverted or subsumed and that those parts of Europe that benefit from it (the western coasts and isles of England, Ireland, and Scotland mainly)...

How can you put a list of datatables into a datatable? It's nonsense to start with! Would you propose putting a list of integers into an integer? A list of buttons into a button? The collection type...

Might one just stop to consider for 2 seconds how likely it is that they would be published if they did not agree with the dominant peer reviewers' opinion? Scientists are just as malleable under the...

Did you ever bother to check what the filename you'd get from that? Would you type the following as a filename in any circumstances?

If you want a filename then you need...

Might be helpful to start with that next time. You'll need someone with either a very good memory or a degree in Ancient History to be definitive about solutions for that! Is there no prospect of ...

Might one ask why you're not using the perfectly serviceable autocomplete options built in to the combobox rather than attempting this rather strange and ever so slightly bonkers method? I can't see...

I'm not sure how getting away with doing it wrong 100 or even a 1000 times is meant to justify continuing doing it wrong (an argument which is all too prevalent around these parts)!

But moving on....

Like the DataGridView, Repeater edits are not completed until the cell/control registers the leave event for which the user must either move to a new cell or leave the control altogether. That's why...

I don't see any open or close commands for the database so it seems safe to assume that ..
