I have a formula, found in an Excel sheet that I have to convert to vb.net...I can't figure it out, eventhough it's seems a quite easy formula to me.the formula is: Mod(X + Int(Y/100000);20)In fact if I render some values...and use the Mod function in Excel or in VB.NET it gives me other results.
View 2 RepliesWith vb.net I would like to select 4 cells in Excel and then pass those cell values along with 1 button tag to a formula in Excel.I press a button with a month, say "May" as text. I want to grab a cell in Excel labeled "May1t" the value of which is the number of hours until may. This is the code I'm using.
xlsWB.Worksheets(2).Range(Month1 & "1t").Value I am able to set a variable with this as the value but,
I want to pass this cell (which will be updating as the time counts down) and 3 other similarly specified cells along with the button tag to an Excel formula.I have something like this:
Private Sub F_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles F.Click
xlsWB.Worksheets(4).Range("B2").Formula = "=MyFunction()"
xlsWB.Worksheets(1).Range(Month1 & "1t").Select()
End Sub
The formula takes the parameters in the order: MyFunction(Cell,Tag,Cell,Cell,Cell).
I have used formula to generate a RowNumber for each Record[code]...
But it displays decimal numbers : 1.00, 2.00, 3.00, 4.00 i want to display only Int numbers in RowNumber : 1,2,3,4,5
I want to write a formula to SUM from column B4 to M4, this should be done using vb.net programming.
I tried using the following stuff:
oXLWsheet.Range(4, 14).Formula = "=SUM(oXLWsheet!$B$4:M$4)"
"=SUM(B4:M4)"
"=SUM(B4,C4,D4,E4,F4,G4,H4,I4,J4,K4,L4,M4)"
Nothing is working for me. I'm getting the following error when I run the code:
"Exception from HRESULT: 0x800A03EC".
I have complex formula calculating the value of a cell and it calculates the value for me. I want to get rid of the formula from the cell and want to retain the calculated value.
I have :
Dim range As Excel.Range = getRange()
For Each cell in range
' What should do to retain the value and get rid of the formula in the cell.
Next cell
i am generation a excel sheet from vb.net and have a question on inserting a forumla from vb.net into an excel sheet.
I am creating this sheet out of vb.net but with a statement like this:
worksheet.cells (1,10) = "myvalue"
For my formula i need the read cellnam like "A1". But i have only the value cells (x,y). How can i get the real cellname for my formula or how am i able to insert a formula with the given information (cells(1,1))?
I have the following columns : (Using Excel Formula)
A B
------------------------
1 | Date | Value |
------------------------
2 | 8/20/2011 | 92.8 |
3 | 8/21/2011 | 92.4 |

I want to calculate the difference between 1st Value (B2) and last Value (last populated row in column B)
Edited :
Using formula : =B2-B6 is not what's required. (I want diff in Cell C2)
I want when the user enters the value in B7 it automatically shows the difference between B2 and B7, when he populates B8 then it shows the diff between B2 and B8 and so on.. I don't want some direct method to do this in Excel and not by iterating all values to check the last value.
I'm using Visual Studio 2010 (VB.Net) and Open XML SDK 2.0. How do you insert a formula into an Excel 2010 worksheet? When I do this I also wish to set the CellValue property of the cell to a DBNull or EmptyString to force Excel to recalculate the cell when the user opens the workbok.

Has anyone created a regex that matches each of the cell references in a given Excel formula? I'm trying to extract a list of cell references into an ArrayList from a provided Excel formula. Ideally, the ArrayList would also preserve any cross-tab or cross-workbook reference information. The key is for the regex to be compatible with any potential Excel formula, as the formula will change with each use.This seems to capture cross-workbook references:
'[.+'!($?[A-Z]+$?[0-9]+(:$?[A-Z]+$?[0-9]+))

View 12 RepliesI am trying to parse the parameters of Excel formulas like "=a(b)", "=a(b,c)", "=a(b,c,d)". I'd like extract the function name "a" and the parameters "b", "c" and "d".
There are loads of examples on SO to parse HTML and so forth, but none specifically for parentheses.
So far, I've got this "=(.+)(([^,)]*)(,[^,)]*)*)" but when I parse "=a(b,c,d)" it puts "a" in match(1), "b" in match(2) and ",d" in match(3). So "c" is lost and the comma before the "d" is a pain.
How can I parse a string like this with an arbitrary number of parameters, ideally dropping the commas?
The ability to parse "=a(b(c),d(e(f)))" would be great...
Edit: I know that a parser is the correct solution and I have used Devin Cook's excellent Gold Parser with great results before.
However, the particular case I'm facing is to extract the arguments from a known Excel formula. Specifically, if the formula contains the string "=Travel(", I know that it will have 4 arguments and if they don't parse it's not a problem. This is simply a "nice to have" function which can fail occasionally without it being an issue.
regex for "=a(b,c,d)", "=a(b,c,d,e)", etc., with the constraint that there will be no nested parentheses or commas?

I have working code that will convert an xls to pdf, however, the code converts the whole workbook and I really just need to select a single sheet out of the workbook, but I can't figure out how to do it.The code I currently use is:
Dim fileName As String = "filepathfilename"
Dim xlsApp = New Microsoft.Office.Interop.Excel.Application
xlsApp.ScreenUpdating = False
[code]....
Where in the code do I need to specify the sheet in the workbook? Note that I will need to make it so that depending on an option fed into the app, the sheet will change, though I don't think that should make a difference, but I thought I'd mention it either way.
