Splitting A DataGrid Cell Value (Numeric) Into Individual Numbers
Oct 17, 2010
I am having dificulties taking a datagrid cell value stored in the following location (datagridVNTPSorted.Item(15), irow).Value) into individual digits to reassign values for counters.
The cell in the datagrid (Listed Above) contains a number between 1 and 5624. I have 4 different counters. If the number was "2856", the counters would need to be updated as follows:
intdirectoryCountDigit1 = 2
intdirectoryCountDigit2 = 8
intdirectoryCountDigit3 = 5

Is there a .split command that would allow me to separate numbers from text in a given string.
Mystring = "1234, this, is, text,5678"
Using the split command I would just like for
this
is
text
to be returned ignoring the numbers. Is this possible?

I have a unbound datagridview which i use to enter data. I would like to make calculations using individual cell data as follows:-
Datagridview1.rows(0).cells(1).value = datagridview1.rows(1).cells(1).value + datagridview1.rows(1).cells(2).value
This works fine but if im using lots of cells it can be quite confusing .I was wondering if there was a way that i can give a cell a unique name so i can be easy for me to identify. Using the above example it could read TOTAL = JAN TOTAL + FEB TOTAL

The problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?

I have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:

I have a mature VB6 program that depends heavily on flexgrids for the display.It appears that DataGrids are somewhat of a replacement for flexgrid?I need to update individual cells over and over and I don't see how to address a single cell. Appears to me that most samples are tied to a database which I don't have.If I set up a datagrid that is say 3x3, how do I read and write from and to say the center cell?

I am creating a process part of which returns a delimited string containing security group numbers, a few examples:
'3|5|6|9|7|4|8'
'5|6|299|27|4|8
'5'
I'm looking for help in fathoming an algorithm for splitting this string into the numbers so that I use each number as an argument within a separate query.Since there maybe only one number, or dozens I cannot work out the logic to make this happen correctly each time.

I have searched alot but can only find info on moving entire rows bound between 2 datagrids, but noting on moving single cells. I have some code below that works ok from DGV to textboxes but not from DGV1 to DGV2.
Dim i As Integer
i = DataGridView1.CurrentRow.Index
Form3.DataGridView1.Item(1, i).Value = DataGridView1.Item(0, i).Value

I'm trying to format a column of numbers is a datagridview and I'm having some problems. This is the code I'm using: dgv.Columns(5).DefaultCellStyle.Format = "n2" If the number I put in the cell is 100.50, it shows up as 100.00. If I try to edit it back to 100.50, I get a "value was either too large or too small for an Int32" error. The cell also is accepting Char data. I want to format the column so it only accepts numbers in a '#####.##' format.

I used a regular expression, which handles both numbers and letters in strings of arbitrary length, in one line of code.
dim rtn as String = Regex.Replace(input, "..", "$& ")
I'd like to take numeric strings of arbitrary length and insert a space every 2 characters.
So 1233456 becomes 12 33 45 6. Is there a way I can use format as string or IFormatProvider, like? That would put a limit on how long the string could be though, right? Since I'm casting to a long.
CLng((input)).ToString("## ")
I'd like to take strings of arbitrary length and insert a space every 2 characters.
123dssas4rr should become 12 3d ss as 4r r

How to programmatically change foreground color and make bold text in individual cell location on DataGridView control (Visual Basic)?
I use "dgMatrix.Rows(r).Cells(c).Value = x" to assign individual numeric values to individual cells in a DataGridView control. My question; is there a similar way to change foreground color and make bold the text in this cell, by specifying the individual row/column cell location?
For example; for cell (row 3, col 5) in the DataGridView make text in cell say red and bold or blue and bold so as to highlight and distinguish individual cell contents. As needed, I will also need to reset these properties (foreground back to automatic/black and font from bold back to regular); the reset could be done globally to the whole DataGridView as opposed to indiviaually by cell.

I have an issue in VB6 that is giving me a major headache. When using a variable defined as a single data type, VB6 will add random numbers to the number i assign to it.
For instance I have a single variable that is manually set to 0.3. Then i create another single variable and set it to 0.25. I have the program add 0.01 to the second variable until it equals the first. But they never equal. I couldn't figure out why when both were showing they equaled 0.3.

best way to check if a textbox has only 4 numbers and isNumeric, for example i need to enter postcodes.I currently have:
If CDbl(txtPostcode.Text) <> 4 Or Not IsNumeric(txtPostcode) Then
MessageBox.Show("Postcode must be 4 Digits", "Error")
But the message box comes up regardless of whether there is 4 numbers, letters, or anything in the textbox. Its also used in the leave function of the textbox.

I have a string I want to parse. I could write the code to do so, but I figured that VS.NET has a parser that should do this for me.however, I can't find it. All the searches I do return info on how to parse numeric values in string form into real numbers. It would be nice if the MSDN search had some ways to allow users to enter more details than just search text and 3 ways to filter out irrelevant stuff. In any case, I also tried things like string.parse (nope - although I kinda figured this would be it.) I also looked at Enum.parse, but the code indicates that it works with arrasy of items, not strings.

I have a textbox which has a numeric value that changes - would it be possible to check if that value matches two numeric values in a text file? and if the value matches then to display some text in a label? The textfile only has fields displayed like so
Horizontal 55
Vertical 16
So I would only need to check if the numeric field in textbox matches the two numbers in the second column. In the past I have use System.IO.File to create/delete/append to files but I havent come across anything like contains.

I'm realy green when it comes to programming but I like to think I am learning quickly. However, I cant figure out how to generate a number of random numbers baised on the vailu of a numeric slider. So for example I am generating a number between 1-12 where each point of value for the slider would generate an indiigual number that can all be added to a final total. I would also like to be able to back the slider down to a previous number and have the same total I had last time I was at position x. This is what i have so far:

I have encrypted a string to something like this:
1. Asak2$)kla1015QAXKFskfa332aSJ2(Ska@Skljcmcel3p.lq,aowpqaskla2@)Skx.:Pdm^),dfs;
what i want to is convert this string to something like this
2. JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3
both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.
I will then confirm the (2) from the client.

For i = 0 To DataGridView1.Rows.Count - 1
cellvalue = Me.datagrid.Items(i).Cells(8).Value).ToString
