There can be multiple of the same order number. In the dataset, I want to have a column "line number" and I want to put in it the value of the linenumber (in this case 1 and 2) per order. In sql , I was able to accomplish this by inserting rownumber() and grouping by order number. Can this be done in .net?
I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible
I want to modify a text file. It has a lot of lines of text in it. I want to add a line after a specific line (in the middle on other lines) and write strings there.
The code i have, writes to a specific line but it also overwrites the text on that line:
How do I limit the number of characters per each line of an RTB to 1 char per line? That is you type one character, after that the textbox should not accept further input on that specific line.-Knock knock -Who's there? -(looong pause..) Java
adding all the numbers in a list box then multiplying it by a %.theres one listbox and two buttons, and two textboxes.i've completed everything but this and can't fibd it in my book. I just looking for pointers. this is what i have which i know isn't right
Dim sum, cost As Double sum = cost = sum * 0.06 lstbox.Items.Clear() lstbox.Items.Add("Total Commission =" & cost & ".")
I am searching for a best practice for Incremental Line Number generation i.e in an Invoice application. I am using VS2005, Sql2005 as a development environment. I need to create autoincremental line numbers for an invoice. I dont want to solve it in Database.
I'd like to know if its possible to copy a certain line chosen by line number(EX: line #3) from rtb1 to rtb2 and then split it word by word and copy those words as new lines into rtb3

I'm doing a notepad project, just because, and in Ms's notepad there is an option for a statusstrip. I'm just having probems getting the line number and I know it's not called column number, more like selection start. When I do the selection start, it works, just not how I want it to like so:
[CODE...]
but when I use that, it acts funny. I have it in my textbox's.keydown event. So if I were to use the arrow keys to navigate around text then it gets thrown off very easily. How would I do this?
i am getting the xml using readxml method. And then display the data in datagrid. But number type columns comes as string type in the dataset. So when datagrid displays , sortingdatagrid columns is not correct. For example it sorts like this:
im addin a new row into a dataset Ipsauto from the MDB IPS
heres the code im using
vb.net Dim cn As OleDbConnection Dim cmd As OleDbCommand Dim dr As OleDbDataReader
[Code].....
ignore the "addthis.Rows(0).Cells(16).Value" theyre values im using to insert to the tablle...i dont wanna use texboxes so im using a datagrid...and no i cant use the database bound to the one i want in a grid to add rows (got my reasons)...thats why i want to do it separetly...
I have a piece of code that works for adding multiple rows to a dataset but I think that it is a lot of code and thought maybe someone may know a better way of doing it. I need to add rows to the dataset based on the selection of a combo box. ie if the user selects 15 the the program adds 15 rows to the dataset.
Case cboQty.SelectedItem = 3 Try Dim dr As DataRow
I'm trying to add a new record in the DataSet in the master table. I'm not including a value in the unique ID field because it is added automatically by the server. At the moment I add second new row it throw me an error �Column 'ContactID' is constrained to be unique. Value '' is already present.� Do I need to set value of id column manually? How?
da.Fill(ds, "tblContactsProfil") daAddress.Fill(ds, "tblContactsProfilAddress") Dim relation As New DataRelation("ContactsDetail", _ ds.Tables("tblContactsProfil").Columns("ContactID"), _
How do I do this for a different dataset? I'm trying to rule out database problems so I made another one and added it, but now I need a table adapter for this one instead of the old database because it keeps giving me an error. I don't see any place to add them and I'm getting extremely angry at these databases.
I am using VB.NET 2008 Express. I had a project with a mdi parent and several child forms. On the child forms, I created a datagridview by dragging the necessary table from the dataset(s) from the data sources window.
Main form - PastorBase Child form - IllustrationList
When I try to debug it, I run into several errors from the code of the IllustrationList.Designer.vb file in this section [Code] However, the moment I make any change to the control by modifying properties or simply resizing it on the form, my change in this code is lost. So I am repeatedly having to change these lines (there are about five per child form). I am uncertain of what I am doing wrong. Should the dataset, etc. be added to the parent form and then called from the child form? Is there some setting I need to change somewhere?
I need to fill a List with data from a DataColumn fetched in dataset. How can I achieve that in 1 step without looping through the entire table in dataset.I want something like this:
Dim lst as List (of Integer) = ds.Tables("Customer_Data").Columns(0)
However the above line is wrong as System.Data.DataColumn cannot be converted to System.Collections.Generic.List(Of Integer)
I add a row to the DataSet using the following code: Dim NewRow as DataRow NewRow = gds.Tables("TitleDataSet").NewRow NewRow("Title") = txtTitle.Text NewRow("Local_number") = nubLocalnumber.Value NewRow("Number_suffix") = txtNumberSuffix.Text etc.
This code executes without errors but the bound DataGridView remains unchanged (without including the new row). Obviously I am doing something wrong or I am omitting a vital command. What do I need to do in order to make the new row appear in the DataGridView? I did not choose to bind the DataGridView directly to the database table because the database is selected by the user at execution time. Instead I bound the DataGridView to the DataSet. I included the command:L dgvTitle.AllowUserToAddrows = True but that did not have any effect.
Solved. Was missing the final command:L gds.Tables("TitleDataSet").Rows.Add(NewRow)
i am making a table through vb.net code (htmltablecell, htmltablerow..) no this table populates with an sql query and works perfectly. but inside this table in one tablecell, i need to add a dropdownlist which shall require a completely differernt query and shall run on its own on each row. so the code is as follows
Sql = "..." rd = ExecuteReader(SqlCnn, Sql) Dim newcounter As Integer = 0 While rd.Read()
[code]....
the ??? in the code is where the dropdownlist shall get populated each time with its own datareader and while loop and query.
In a project, I have a dataset with two table adapters. Without warning while I was modifying one of them in design mode, I received this error. I have typed the contents of the dialog box exactly as they appear - so no additional information was given, and the error code was "-1".
I have a question about using writeXml. When I use this method, it writes to the specified xml file like this: <safety><Incident> <Name>Jason</Name> <AGE>23</AGE> </Incident> <Incident> <Name>Frank</Name> <AGE>25</AGE> </Incident></safety>
But, I would like to add these nodes to a parent node, i.e.: <safety><SomeNode><Incident> <Name>Jason</Name> <AGE>23</AGE> </Incident> <Incident> <Name>Frank</Name> <AGE>25</AGE> </Incident></someNode></safety> I am creating the xml by first creating a dataset (connects to an SQL db and runs a query, filling the dataset) and using ds.WriteXML(myPath)
There's a thread that i'd read wherein you reply regarding on shortcut on populating a listview with databatable or dataset, but i forgot it. How did you populate a listview with datatable or dataset with just one line.
In datagridview .DataSource how about in listview ?
