VS 2010 - Creating Multiple Splitters Then Adding To DataGridView
Feb 27, 2011
I need to create multiple splitters, then getting that data and adding it into a DataGridView;
AAL1238:KSEA:KORD:1:1492.9:SEA;
AAL782:KSEA:KORD:1:1492.9;
AAL1848:KSEA:KORD:1:1492.9:;
AAL1360:KSEA:KORD:1:1492.9:;
AAL1804:KSEA:KORD:1:1492.9:;
AAL6796:KSEA:KLAX:13:830.785:;
The First Splitter will be a ':', then the next one will be a ;. Per each line up there, I need to add that content into a row into a datagridview, So if you were to look at the datagridview, It would look like that data above exactly, But separated into the correct columns.

I am trying to Add multiple rows to a datagridview using the below code, but at the moment it only adds 1 row and when i click add again it overwrites the previous entry and not add a second row:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim dt As New DataTable()
dt.Columns.Add(New DataColumn("Make", GetType(String)))
dt.Columns.Add(New DataColumn("Model", GetType(String)))
[Code] .....
How do I manage to append the previous entry in the datagridview so multiple rows get added?

I have a windows applicatin built using vb.net 2005 - backend webservice that uses a sql db. I'm working on a form that contains a datagridview that I bound. My pic below to displays the outcome. I have a combination of dropdowns, textboxes, checkboxes, etc in the grid. I now need to add several filters and would like to know, what is the best approach:
1) adding the filters to the header row in the grid.
2) adding the filters outside of the grid as you can see i've started to do from looking at the pic?
I've been reading how it's possible to add them to the grid; but not sure if this is possible to do this when there are controls other than text boxes inside the grid.

I am currently trying to read an XML file and display the information within a Datagridview. I currently have this working using the below
Dim xmldoc As XmlDocument
Dim xml_nodelist As XmlNodeList
Dim xml_node As XmlNode
xmldoc = New XmlDocument()
xmldoc.Load(openFD.FileName)
[Code] .....
Basically what I want to be able to do is for each <ADVERT> node, so in this case there would be two, I can get the information from both the TITLE and NAME attributes and add them into the Data table which then gets displayed within the data grid view. Currently I can only get the TITLE attribute values to show?

I am looking to create a startmenu like thing in my game, I have my 'desktop' all sorted out but struggling to create a startmenu that I can easily add stuff to via code. For instance when the form starts it will check a directory for DLLS, query each dll which will return a name. I then need to populate this menu with the 'installed' applications my game has. I have a start equivalent button then I just need to the actual menu.

I'm trying to develop an application in VB 2010 that will monitor files in a directory that the user specifies. The problem is, this application is going to be installed in diferent computers with diferent Operative Systems (windows 2000 and XP).Is this possible? or should i change mi programming lenguage?Another thing that comes to my mind is that maybe i should use diferent frameworks (i'm afraid that framework 4.0 may not work in Windows 2000).I apologize if i'm posting in the wrong place, i'm new here.

I'm creating a twitter account manager using the Twitter API. I have multiple accounts, over 10 of them. I want to automate all 10 of these accounts to do certain things, now the way I started to code the program was so that it would accommodate only one account, and all the codes worked perfectly and were managed by individual timers for individual processes that I wanted done. i could tweet between certain intervals, follow people who tweet certain things without me being on top of it.
Now the problem is that I've been trying to create new instances of subs that I've already created so that I dont have to create 10 new subs with the exact same procedures. I'm pretty sure it's impossible to create copies of subs dynamically or within a loop but it didn't stop me from trying. So question is how can I edit a program that was designed to accommodate and automate only one account, to potentially accommodate over a 100? I don't need codes or anything I need ideas so I can try them, but right now I'm completely blank.

I have a form which has a textbox named "textbox1", and a button named "Button 1". Button 1 is meant to be a submission for textbox1 (i.e. when button1 is pressed, the value of textbox1 is saved and remembered). I want the value of textbox1 to be remembered on any computer, but I need it to be update-able too.I tried using settings to do this like so:
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.TextBox1.Text = My.Settings.TextBox1
End Sub
[code]....
but the problem in doing this is it only works for the current user. When the application is then put on another computer the value is blank.

I know how to add a single node to a top level node in an XML document, but I cant figure out how to add multiple (nested) nodes to another node. For example, I want to add this node structure to node called "PaymentInformation":
<Prepaid>
<BillShipper>
<AccountNumber></AccountNumber>
</BillShipper>
</Prepaid>
Do I have to add each node separately or can I add them all at once?

I am converting an older software package written in VB 6 to VS 2010.Not to incredibly painful but planning for the future as we have had lets say a few issues with VB 6 on our current layout of multiple OS and this is my first real project lead.We are a smaller job shop and we move on a rotation of new PC's/OS's come in to replace broken or exhausted older PC's in the front office and move the older PC's out to the shop floor.We have an array of different OS's ranging from Windows 98 and Windows 7 (32 bit and 64 bit OS). By the time I am done with the conversion we should be sitting comfortable with a range of PC's from XP and up. When creating the executable for my project is this something that can be handled ahead of time, creating multiple executables for specified OS, or an all in one package executable?I was looking to see what people had as suggestions at handling this.We haven't even bought VS yet and are looking at the VS 2010 Premium package, do I need Ultimate?

Ok, I have this code... and it works. If I want to add it to say... a checkbox or something of the sort.
Public Sub groupaddarray()
Try
'Alpharetta Staff
If Form1.CheckBox23.Checked = True Then
Dim grp As IADsGroup
[Code]...
My question... how can I double click the listbox, and then it keeps adding these groups to say... another text box, and when I click add groups it will read the textbox, and add multiple groups instead of just the one?

Does the Express Version support adding multiple soultions (.sln) to a project or is this only available with the Professional version.I see that I can add a DLL as a reference that was built in 2010, but it is not letting me step into it with the debugger (or recompile changes to its source).

I am trying to insert an initial line (0) into a datagridview (named params). The program will then read each cell in that row, pass them through a function and return values be placed into the next line (1). This will continue until one of the parameters reaches some set point. The problem that I am having is that when I try to insert a new line, it appears above the initial one and not below it like I would like it to.
Here's my code so far:
Private Sub HurricaneWinds_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim init_xrange() As Double = New Double() {0.0, 0.0, 0.0, 40.0, 0.0}
For i As Integer = 0 To 4
params(i, 0).Value = init_xrange(i)

Dim DS As New DataSet("aa")
Dim tbl As DataTable = DS.Tables.Add("bb")
Dim xRow2 As DataRow = tbl.NewRow()

I have a datagridview that is binded to an database file. I also have a group of textboxes that are also binded to the same database. I wanted the user to add new inputs from the textbox to the datagridview. I tried using the code
Me.tableBindingSource.Addnew But instead of adding the new inputs into another row and column. It edits the input that is on the datagridview that is currently on focus before I can add new inputs.

What to use for adding multiple attachment to a email. I'm using VB 2010.
First, I have a Form in my company web site to fill a reclamation ..... when you fill and send it, it convert the form into a PDF, save it in the client side "TEMP" and finally get the PDF and send it to a email..... that's perfectly fine. I add to the form the capability of attach multiple files with file upload to the same "TEMP" and displayed in a Grid View to remove or add files and send everything to a email, the attachment capability is working. Everything is working with the PDF not the files(attachments).
There is a way to get the multiple files from the "TEMP" folder and add it to some dynamically variable (array list, attachment collection, list collection, etc.) so all can be send to the email. I already know the way to put it into the email with the PDF.
The problem is to get the files and add it to the dynamic variable and that it work with the email. If the code is need it.

My below is not an error. It just I need an alternative way of doing thing. I have a DataGridView which has a DataSource of DataTable on a Form. In this form, I have a 'Remove Selected' button which will remove all selected rows in DataGridView. And another 'Remove All' button which will remove all rows in DataGridView regardless of rows selected or not.

I have a datagridview which is bound to a local databse table through a Linq to SQL class.
Everything works as I would expect, when the application runs, up to a point.
If, in the datagridview tasks pane I enable Adding, Editing and Deleting all work as expected.
If I disable Adding & Deleting, leaving Editing enabled, Editing works as expected.
If I disable Deleting & Editing, but leave Adding enabled, Adding does not work, despite the row for new records being displayed. I can move around the row but not enter data.
I suspect somehow its the datasource as opposed to the datagridview that is the cause of my problem but as I say, I can add rows if the Enable Editing option is selected.
Changing the relevant properties programatically makes no difference.
I've been searching for the reason for a couple of days without success.
I have a workaround, by leaving Enable Editing set and programatically setting each row during the RowPostPaint event to be readonly except the row for new records. I would just like to understand what is going on.

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

I have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)

I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?

I have written a text editor for an assignment but I am struggling on where to start on this bit. What I Want To Happen:- When the user saves there work I want the name of the file to be shown next to the name of the program at the top left hand side of the form. I am not sure If I just need to create a simple sub routine for adding the name of the file then calling the method in the save as routine.
