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.

I'm trying to upgrade an Excel VBA workbook to a VSTO Excel Add-in in VB.NET using VS 2010. In the original (i.e.- VBA) version I have a modeless UserForm (called frmMain) that floats on top and is visible at all times while the user is still within the Excel application, but is not visible if the user moves to another window outside of Excel.
For example, within Excel the user can click on any worksheet tab, select any cell, etc. and the UserForm is still visible. This is exactly how I'd like it. The problem is, that in the new VSTO add-in, I can not get the Windows form to mimic this same behavior. I use frmMain.Show() to show the form as a modeless form, but the moment the user clicks an Excel worksheet (i.e.- activates a worksheet) the form becomes hidden behind the worksheet.

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:

I can do all the VB side of things but I don't know Regex but know it would help. I'm in a bit of a rush to finish this job for work because I finish working here in 2 days and need to get it done before I leave!

View 1 RepliesI'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 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.

View 2 RepliesI 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.
