I am trying to evaluate cells in Excel for invalid chars (I use them as lookups). They come from other sites so I need to quickly strip out bad chars (high ascii). I wrote a simple function that tries to loop through the positions of a cell starting from the end until it gets to the begining. It looks for the first ASCII char between 48 (ASCII for number 0) and 122 (lower case z). Everything else it would discard as junk and continue looping until it gets a good character. This will be the rightmost char to include so I could use a left(string, index) to extract valid data from a cell.
I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.
I have user form that copies data form on excel sheet to anther after the paste takes place.I need to perform a cleanup process.

I would like to update an Excel cell using the cell name, such as "A1", instead of using the row and column, such as (3,2). I haven't been able to do it. Here is the code I used to update the cell by row and column. How would this code be updated so that it updates the cell by cell name instead?
"Form1" has a ToolStripContainer1.TopToolStripPanel which contains a ToolStrip with buttons. The buttons work on ONE click when "Form1" is active.If I click on another window and then return to "Form1" the ToolStrip buttons take TWO clicks to activate.The first click returns focus to "Form1" and the subsequent click fires the button event.I want the buttons to work on the first click and not require two clicks.Note that ordinary buttons on "Form1" that are not part of the ToolStrip work on the first click when returning from another window/form?

I am using Visual studio 2008.I have an application that reformats an excel spreadsheet. One of the operations is to copy the contents of the cells from the source to the target sheet. One of the columns has numbers. In excel, if the column is not wide enough, it will display the numbers as "###". For instance, if i have a number 99 and the column is not wide enough, it displays "#" in that cell. The problem is that when I copy this cell to my target sheet, I get "#" and not 99.
I'm trying to make a class that reads data from an excel file, which is going to have 3 columns and any number of rows.I made a property named Data, which is supposed to return an array of Strings of all the cells in the Excel file.

I have a spreadsheet that I need to trim 3 columns. I have scoured the net but can't find anything that I've been able to use to trim each cell in columns A, H and I. I am using Excel 2003 and VS2005.
I am writing a VBA code for testing different combination of 24 variables and recording a result which corresponds to each combination of 24 variables. so I have an equation with 24 variables and one result. In excel I have one column which contains the 24 variables and the column next to it contains a figure which shows the result. what I need to do is to write loops to change the 24 variables between 1,2, and 3 and then record the result of the equation for each combination of 24 variables. I have written the loops (24 loops) and can record the result for each combination, what I have to do at this stage is to record the combinations which relates to each result.
As there is only one result for each combination of 24 variables I was wondering whether I can tag each variable (in each cell) in a way that in the final sheet in the cell next to the result cell I can write for example 111123123111233311121232. This means that after each loop I am taking the values for each variable in 24 cells and put them all together in one cell in the final sheet. These variables are changing in each loop, the label should change as well after each loop so after the completion of the code I can find out which combination relates to which result. I have tried to define an array or matrix but I couldn't fix the problem. This is the input sheet (the code changes the values in the cells in A column after each operation)
If you know the cell number that you need to write to in excel, say E3 what would you use for the VB2005 code? I can't seem to find an example on this!

I am working on applying date validation to excel cell(range) from VB.NET.
Private Sub DateValidExcelRule(ByVal worksheet As SpreadsheetGear.IWorksheet, ByVal DateRange As String) Dim dt As Date = CDate("1/1/1900")
[Code].....
When I enter 4 digits whole number 7777 it is validating correctly showing message Enter Valid Date, but when I enter 5 digits 77777 it is accepting the value and converting it to 12/10/2112 value and not showing any error message.
Here all I want to do is I want to validate the cell value to any date format mm/dd/yyyy.
