C# :: Save Xml In An Excel Cell Value Causes ComException?
Mar 16, 2010
I am trying to save an object (Class1) as string in a cell value. My issue is that from time to time I have a ComException:HRESULT: 0x8007000E (E_OUTOFMEMORY)(It is kind of random but I have not identified any particular pattern yet) when I write the value into a cell. Any ideas will be welcome
For illustration purposes:
Let Class1 be the class to be converted to an Xml string. (Notice that I removed the xml declaration at the start of the string to avoid having the preamble present- non printable

I have done quite a bit of research on this issue and haven't came up with anything definitive yet. I am having issues with Excel randomly getting ComExceptions while writing out reports. I am using a Visual Basic 2005 (framework 2.0) console application to create these reports. The problem has been difficult to figure out because it occurs in random places while writing out reports so I can't catch the error to see the problem. I have looked through the differing items that it breaks on and there is nothing odd about them that would cause any of these problems.

Here's my code (for convenience, I've included only the code that seems relevant to the problem):

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 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 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 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.
