Since the parameters took type object, I figured maybe this would work, but got no luck. I also thought of enumerating each letter to a number, but the columns in the spreadsheet aren't as normal. Meaning, they're not
A B C D E F G
They're actually...
A B C D E T AZ
I don't know if this makes a difference in the numbering of the columns. The question should be obvious, but just to reiterate, how can I get a cell based on a row number and column letter?
I have an internal process that requires data in a very specific format. Nothing I can do about that. So in my VB.NET program I am trying to output a number with a terminating decimal and nothing after it. I tried
I've managed to work out how to read EXCEL cells via static values. Ideally I would like my application to check the third column of the EXCEL sheet and if there are no entries on a given row, it should display the coresponding row of colums 1 and 2...for example if (C,3) contains no entry then get values of (A,3) and (B,3)...then mark (C,3) as pending by writing a value to (C,3). Here is my code at the moment
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?

I'm developing a small application that creates Excel files with user details. I'm developing this in vb.net 2008 express edition under Windows XP SP2 and with Office 2003.My target PC is running Windows Vista. I'm able to run my program without any problem and even the Excel files get created without any problem on this PC.However, the problem is when I try to open one of these created files in Vista, I get a message like below:
"The file you are trying to open, "TestMe.xls", is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?" If I click yes, it opens up properly. This is a headache as it opens up in my developing PC without any hassle. I'm sure its something to do with the Excel reference I've made in my PC (which is running Office 2003).How best can I save this file so it opens up in Excel 2007 without the above message.
Is there a format string to format a decimal to 000000000,00. So first 9 digits, right padded with zeros if needed; a comma as fraction separator and two fraction digits. 0 => 00000000,00 12 => 00000012,00 987456,456 => 000987456,46 So something like myDecimal.ToString("D9") together with .ToString("F2").

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 throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.
Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11
Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM
For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation
BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.
I have a field defined as string for phone number which in my SQL cast to Integer.
Format the column as follows
DataGridView1.Columns("ContactPhone").DefaultCellStyle.Format = "(###) ###-####" This works as expected for cells with a phone number but for cells without a phone number I get
{}- Which seems like the proper output for what I specified.
is it possible to format cells with no data (no phone number) to show up empty in their cell?

I have created a custom column type for a datagridview. I have created a class for the datagridviewcolumn and a class for the datagridviewcell. Within the datagridcell class I am using the following code for the font.Dim fnt As Font = parent.InheritedStyle.Font How do I change this so that I have control over the font color for that cell? I am fine with the font just not the color.
