Dec 28, 2009

I am using a button to read a txt file and then make and then make an xml file. What I want to do is clear the current xml file and add the new data row by row.I'm getting stuck at "addrow". I don't know how to do this. Anyone know the solution? I've been googling for 3 hours

The part where i'm stuck is Email_To_Data.Tables.Add.NewRow(). I just don't have any idea how to start adding new rows to my cleaned xml data.[code]...

Serialize Datatable To A Binary File Then Add New Rows To File

Apr 29, 2012

I need to save a datatable to a binary file , in binary format , in order to make the process fast because the datatable may contain up ten millions rows. So , XML is not favorable because it makes the file large sized , and the process will be slow.

I managed to save the datatable to a binary file , and it works fine , but the problem when I try to add new rows to the existing binary file (using a datatable with the same schema , but different rows data) , it copies the schema of the datatable to the binary file, making it very large.

Deleting Rows In An XML File

Apr 18, 2011

I have the following xml file output below where Deleteme="true" is written when the user clicks on the row's checkbox. I was thinking that once the data is flagged this way I could read the data back in, somehow delete each row specified as above, and then save the data back out.

Combine Each 5 Rows Into 1 Row From Text File?

Apr 7, 2012

I have a long text file with job descriptions with each description split over 5 rows. (2 examples are below.) I would like to combine each of the 5 rows of the single description into 1 row. so for example the 10 lines below would be combined into 2 rows so that I can then import into SQL server and clean it up. I'm fairly new to vb.net but I've written the code to import the text file and export it again but I need to process it after import.

Add Rows Inbetween Rows In Gridview Based On Parent And Child Node

Jan 19, 2011

I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.

These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.

VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?

Jul 30, 2010

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

VS 2010 : Combine Similar Rows In A Datatable (the Rows Only Differ By One Column)?

May 8, 2012

I have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):

'Sub table 1
xx|C201 |02300877 |Samsung |....
xx|C201 |02300877 |Toshiba |....
xx|C213 |02300877 |Samsung

[code]....

p.s. For the fourth column, Manufacturer information , I want to do the same and I'd probably get something like this for the final table:

xx| C201,C213,C606,C619 |02300877 | Samsung
xx| C201,C213,C606,C619 |02300877 | Toshiba
xx| C303, C305,C712 |02301163

Accessing Specific Rows And Information From The Rows Using VB In An Access DB

Mar 23, 2010

Public Shared Function isMatch(ByVal username As String) As Integer
For i As Integer = 0 To table.length - 1
Dim cellValue As String = table.getRow(i).getCell("Alias")

[Code].....

I have the code listed above as a translation from a Java snippet. The problem i have is that in Java, my table was stored as a dataset and as such, the methods were easily identifiable by "getRow" and getCell" using specific numbers and column names. However in VB the information is stored in an MS Access database (which i already have an open connection to, called: "_SalesPerformance_AnalyticsToolDatabaseDataSet12") and as such i do not know the correct way in which to iterate through each row in the database, checking a specific column against an already specified variable and then returning an integer based upon the value of a seperate column in the same row.

Check Lines In A Text File With Rows In Database?

Mar 19, 2012

I have a text file with some call records in it. Each call record states a line in that text file. And what I want to do is that parsing to database with a 100% success rate. Due to sometimes the SQL connection might get buggy or stop or w/e so it came to my mind that I should make some function or maybe a stored procedure to check whether the requested/selected or whole lines in that text file have been successfully added or not to the database. Let's assume I have 10 lines in a text file called "log.txt" like:

call line 1
call line 2
call line 3
call line 4

[code]....

And assuming that the SQL connection to the database got stuck somehow(buggy) and it stopped inserting those lines to their respectively columns. Let's say it parsed lines from 1-6 and it stopped there, that's where I need the app to tell me that it stopped and continue inserting immediately where it stopped at to the end from 6-10th line. What am I supposed to do? The smoothest way so that the processor doesn't get overwhelmed (in case there are like hundreds of thousands lines). And should it be written in SQL as a stored procedure or written as a function from VB side.Toolkit : Microsoft Visual Studio 2010 Ultimate - VB.Net language & Microsoft SQL Management Studio 2005 - SQL Database.

Modify Txt File: Break Rows In Multiple Columns?

Apr 8, 2010

I have text files with X Y Z data. There are three columns, one each for X, Y and Z and the files are tab delimited.The value of X is constant over a (repeating) range of Y. Z is the dependent variable.

For example:

0 1 44
0 2 32
0 3 22

[code]....

I need something to take this file and break into multiple tab-delimited columns. In the output, I would like the initial range of Y to be the first column (ie 1 to 4). Then, the second column should have the Z values for that domain (X=0 in above example). Then, the next column should have the Z values for the next domain of Y (i.e. 1 to 4 again, but now for X=5 in above example) and so on. Also, I'd like the first line value in each of the new columns containing Z values to be the X-value they were originally associated with.Thus, I'd like the output file to look like

Y 0 5 9
1 44 66 51
2 32 11 72
