View 1 RepliesMy main goal is to have an excel spreadsheet that automatically plots the overall success of my stock portfolio over time (% change over time). I've been able to incorporate stock data into my spreadsheet by linking it to the web, but the trouble is the spreadsheet will keep no history of what the previous stock values were, so I can't graph how things change over time. This sounds like it might be too complicated to be built in to excel, so I was wondering if anyone knew how to program this in Visual Basic. Maybe something like this.... If refresh then new cell plus new time stamp. Another possibility would be to have a whole bunch of cells that refresh only once but at longer and longer intervals, e.g.,

I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.

From what I can gather, it more than likely comes down to this line:
Dim Obj = CType(therange.Cells(rCnt, cCnt), Excel.Range)
All I need is the text from the cells, not to create an object for each cell (and then not send them to garbage collection).Is there an easier way of just getting the text? Ideally, if I can get a method for getting the text values of the cell, I'd like to get the multiple rowArray()'s added to a master array and update the program's values later.
EDIT:I also realize that I have two options if I were to create a master array, say mArr, to hold all the data.Would it be better performance-wise to have mArr to be large and the sub arrays small, or mArr to be small and the sub arrays to hold more of the information?I ask because the files that will be imported will have more rows than columns, so I was wondering if there was any "set" way of doing it.

Is there a way to get the max number of user filled cells in an excel sheet without passing a range or iterating through max cells per excel spreadsheet?
Right now I have
Imports Excel = Microsoft.Office.Interop.Excel

Dim oApp As New Excel.Application

Dim oSheet As Excel.Worksheet

Right now the oSheet.Cells.Rows.Count = 1048576 and looking through the sheet there is less than 1000 rows of data.
What I'm trying to do is extract values, colors, comments, and any formulas for a range of cells in a given worksheet. The ultimate goal is convert a spreadsheet someone has been using as a database into Access tables.
worksheet.Cells(row,column).Value 'extract value WORKS
worksheet.Cells(row,column).Font.ColorIndex 'extract color index WORKS
worksheet.Cells(row,column).Comment.Text 'extract comment WORKS
worksheet.Cells(row,column).Formula 'extract formula DOES NOT WORK
The return value for .Formula is same as .Value. That's not what I need. I'm looking for a textual representation of the formula (to extract rate information embedded within the formula).
