where field1 is not null and
field2 is not null and

I have a Dynamic DataTable Created at runtime. The Setup is like so
Id | Name | Age
-----------------
3 | Mike | 21
6 | John | 43
8 | Sara | 34

Such as a statement to change AGE to '33' WHERE ID = '3'
My code So far is:
-[VB.NET]-
Dim MyRow As DataRow = From column In MyTable.Rows Where column("Id") = 3

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?

View 6 RepliesI have been using this code to find the value of the cell in a datagrid view

eRow = dgv.CurrentRow.Index

This works fine when the columns unless the user changes the order of the column.
So what I am trying to achieve is to find the value if the cell even if the order of the columns is changed. Is there a way instead of saying column (0, eRow) I can add (ColumnHeaderName = "NameHere", eRow) or something along those lines.
I have a table located in a Microsoft Word document. changes has been enabled in this document. I see that I can get the collection of revisions using "ActiveDocument.Range.Revisions" . I also see that I can tell if the revision exists inside a table using "Range.Information(wdWithInTable) " .My question is this:I really need to find out the "ID#'s" that contain a revision on the "SomeText#" column.So for example, if "Some Text 1" was revised, I need to output "ID-1".I am puzzled as to how to implement this logic. Does anyone know of a way to go about this?

I have developed a windows based application using visual studio 2005 called DMS. On the client side, this application runs on asp dot net framework 2.0. We have created its setup file which has to be installed on the client pc. After the installation of the application, some of the users get the error message as:
DMS.exe - .net framework initiation error Unable to find a version of the runtime to run this application
(I have also attached the screen shot of the error message.) Trouble shooting done by me:
a. I had tried the re-install Dot Net Framework 2.0.
b. Scanned the PC for virus attack.
c. Install dot net framework 2.0 first and then the application.
d. Un-install and re-install the whole application.
But none of the solution works. The only thing that works temporarily is un-install the whole application and re-install it. Then it works for a few hours.
