VB.NET code to change Excel 2007 Column Cell Format from Text to a Number no Decimal.
Right now Column F shows values that look like
3E+13
3E+13
Manually changing it to a Number with No Decimal shows the correct value.

30000041582875
Of course I would like to automate this.

Every week I generate a CSV report that adds an extra space to the beginning of my date column. Because of the extra space, Excel recognizes the date as text and will not format the information as a date. I have tried the Right() function but once Excel recognizes the date as text, it will not convert to a date. Can I programmatically address this issue in VBA and how?

I want to run a macro that searches through the cells and tests to see if they have a substring sitting at the end of the value that is in the format "-Q[number]-[number][number]" OR "-[3 LETTER MONTH ABBREVIATION][number]-[number][number]" OR "-[3 LETTER MONTH ABBREVIATION][number][number]-[number][number]"and then if the test is true, the cell color is changed to RED.So if I ran the macro on the example I gave above, it would turn the cells with the following values red:
4565-Q1-09
454354-FEB2-09
546-5-MAR03-09

I am using decimal numbers to be able to sort correctly in Excel; however I want to have a column where they are displayed as fractions. I have made a function to convert them to fractions as text ( 1.625 converts to "1 5/8 dia."). I would like to make the 5 superscript and the 8 subscript. I can do this manually by highlighting the number and formatting, but I would like to do this in code.
View 1 RepliesI am exporting text to a worksheet with fixed column widths and there instances where the text in the cell does not fit and will obviously overlap to the cell on the right.
I'd like to prevent that overlapping by reducing the font size of the cell if it is necessary. The problem is how to check if the text does not fit.

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.

After writing to excel, most of the cells in excel are correct. But some of the cell's text comes as ####### however if I click on the cell, formula bar shows the correct result.
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'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really). Well, I am adding a history to it and it allows the user to see the last 50 records searched. They get a grid showing the records. This, thus far, works perfectly What I want to do is this: I want to select a record (A cell) in the column 'Dog and have the text of that cell appear in a textbox. This is what I've tried with no success.

How to format that cell ?
I am trying to export cells in a DGV that has time formatting. The data for the cells is stored in an Access database that also is set for date and time. My problem is when I export the DGV to excel, the date and time show up as pound symbols until i click on the cell, and it adds the current date with the time even though in the app I only put in the time. All I want is the time to show up in the Excel cells and not to have it show up as pound signs.
