i have write all this value in another text file by adding the title.in my original file's line i must check whether the line contain any MIL value if not, I must write first T1 the below T1 i must write all the line which not contain MIL value until i reach a line which Contain MIL value. If the line contain 39MIL the i must write first T5 then followed by all the line which contain 39MIL until it reach the line which contain another MIL value. Let say 50MIL. the i must write T7 then followed by all the line which contain 50MIL. I sort my original file alredy. so the original file will start from the line which dont have MIL to 39MIL,50MIL,75MIL and 100MIL. Mu output file will look like this

Is there a way that I can get it to show the rich text in a cell of a datacolumn of a datatable?

Jun 22, 2010I'm calling a GUID with a system function and trying to insert it into a database as a primary key. i'm using vb 2010 .net framework with sqlce server making my datatables. the column is AutoNumber which i set up to be a uniqueidentifier. the length is not adjustable and set at 16. i got all kinds of not parsing query errors. i've edited the insert statement a bunch trying to figure this out. i've went so far as changing the table schema of AutoNumber to be just a nvarchar with length of 100. it's something to do with how i'm inserting the GUID. in the code below i'm converting it into a string then inserting it into my table. is this wrong?? i've tried finding other ways of doing it but it's a little confusing. everything else in the code works perfectly it's just this part that is keeping me from completion.[code]...
View 2 RepliesUnable To Insert New Row Into DataTable
Feb 13, 2011I am fairly new to visual basic 2008 but not to visual basic(vb6). I want to insert a new row in the database table (library.mdb). I connected the database into my project and is bounded by a dataGridview control. I have no problem in getting the records from the database. I used the code under click event of a commandButton, after clicking the button neither the record inserts in the database table nor the program generates any error. The code I used is :
Dim bkrow As LibraryDataSet.Book_MasterRow
bkrow = LibraryDataSet.Book_Master.NewBook_MasterRow
With bkrow
.B_no = B_noTextBox.Text
.ISBN = ISBNTextBox.Text
[Code] .....
Here Book_Master is the database table. LibraryDataSet is the dataset, Book_MasterTableAdapter (not used in the above code) is the TableAdapter. Is there anything missing in the above code? Is there any other method to enter data into the database in visual basic 2008?

VS 2008 : Insert And Remove Specific Characters From A Cell?
Jan 18, 2011I have a form with four checkboxs and a textbox for an id number.I also have two tables in a database. The first has a column for the users Id, Name, and a column called Points.The second has a column for Id and one called Letters.What i want to do is, after the user enters the id number, and the user clicks checkboxA it should add a certain number, lets say 5, to the "points" cell for that id#(in the first database), and it should put the letter "a" in the "letters" column (of the second database) for that id number. Also, if a user deselects a checkbox it should remove the "a" from letters and subtract 5 from points.Also there will be different letters in the "letters" cell, so i cant just clear it, but i have to remove the specific letter.

View 2 RepliesInsert An Entire DataTable Into A SQL Server At Once?
Oct 7, 2009I have a SQLClient.DataSet in VB.NET, and I want to insert the entire thing into a SQL Server table without having to do the following:
[Code]...
Since I've got close to a million rows (all pretty skinny, so it's not much space), I obviously don't want to run this loop and generate a million INSERT statements.
I know that one option is to use a linked server when I initially fetch the data, since it's coming from another SQL Server, and just have it to the INSERT from there. However, if I already have the data in my application, is there a more efficient way to bulk insert it? Can I somehow pass the DataTable as a parameter to SQL Server and have it sort it out and insert the rows?

Database - Insert A DataTable With Existing Key To A SQL Server Table
Mar 18, 2010I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields:
QuestionNumber (unique integer key)
QuestionText
QuestionType
In my SQL Server database I created a Table called "QUESTION" with the same fields.
QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?
Refering To DataTable Columns And DataRelations With INSERT..SELECT?
Dec 3, 2008There are plenty of SELECT (...) VALUES (...) statements and Parameters phrases to go with the VALUES. Those appear unhelpful to me as I have no form fields or datagrids and will be working with all the rows in a DataTable in a DataSet. Once started, this application will run to completion, writing as few as 10000 rows or as many as 250000 rows
My Task is to write out the contents of each specified DataColumn in the DataTable, one DataColumn at a time. The insert will also include the key columns and use the datetimestamp of the records as a criterion. Nulls in the specified columns are included.
My source is a DataTable, my target for the Insert is a "tall-skinny" table in an Access database. There is a smaller DataTable that is related to the source DataTable, if I was writing from within the AccDB I would use Joins. I have created a DataRelation, but have no idea how to use it in this context..
I have tried many different SQL statements but they all fail on Select. Here are snippets of the code:
'now, instantiate the specified DataTable from among the DataTables filled above
strDDTableNm = CStr(rsDDTblNms.Fields("Table_Name").Value)
Dim dtSrcTable As DataTable
