View 7 RepliesI am currently using the code below within a VB.Net application to find specific text in a Word document. The text is surrounded by symbols represented by the character codes in the .Text statement. The code below is working fine. The issue now is that sometimes the desired text within a document has been marked for deletion and appears as tracked change within the document. I would like to find only the desired text that has NOT been marked for deletion. Does anyone know of a way to determine if the found text is a deletion?

I need to find rows in resultsets that have every column without null.these resultsets got variable number of columns.currently, the only way that I can think of is creating a view on each resultset and filter this way:
select field1, field2, field3, field4, ...
from "huge query"
where field1 is not null and
field2 is not null and

and then in a storeproc/function or .net code(c# / vb.net) loop through all rows / columns and flag or remove every row that got any null?
I have a Dynamic DataTable Created at runtime. The Setup is like so
Id | Name | Age

View 3 RepliesI have a datagridview and the user wishes to key some text in a text box and press a find button.The text to be looked for could exist in any columns in the grid (I want to exclude hidden columns).The search is to start at the row the user is currently at. If it gets to the bottom of the grid and still not found the the search would start from the first row of data.
If a match is found then the row with a matching value is to be highlighted.I've looked at using the position and find properties of my binding source but I think this will only let me find on one column and only from the top?Do I need to programmatically loop through the rows in the datagridview and search for the text or may there be a better method?
