VS 2010 DataSet Append Write?
Mar 4, 2011I am using a dataset control on a form to store and read data from XML files. So far I use the following to write info.
VB
Dim drow As Data.DataRow = DataSet1.Tables("item").NewRow
drow("path") = strFilePath
drow("id") = strCreationDate
[Code]..
The problem is I need to APPEND data to the same file. What I do now results in the same file being overwritten. I am dealing with large amounts of data, so I would love a way to append to the file without the need to re-read it with each save.code lines 1-4 are in a loop so that at one time, they add a few hundred rows to the DataSet. After that loop is when the save takes place. However, I want to run that loop again and again every so often to update that same file.

Jun 22, 2011I have an excel database with one column and thousands of rows of "number" data. I need to import the data into my form read the first entry, run an algorithm then move the result to the second column then move to the second entry and so on. I am having issues with where to begin. I am able to convert the excel database to a text file if it makes it easier.The algorithm that needs to be ran consists of reading each character one at a time and is as follows:ENTRY example: 12358458754The characters 1,3,8,5,7,4 need to be summed then multiplied by 3. These are all the characters starting with the first one and skipping every other one. I will call them "odds" (not referring to numeric value)The characters that are skipped, I will call them "evens", need to be summed together then added to the result of "odds".

Will VS 2010 Express Read, Write To Random Access Files
Apr 19, 2011I have recently decided to give .net another chance, but i have a few questions about it before i get really into it. RE: Files, I use random access files to store data as opposed to databases (namely i don't see the need for a database for storing so little information(records <200 max) knowing that it is an older system and less "cool" i don't care...) Will vs2010 express read, write to random access files? Would it be done kind of like vb6 (which is my current vb version)? I will be needing to print the text of rich text boxes, is vs2010 express capable of doing this?
