AddNew - Form Where Show A List Of My Rows With A Given A Table
Jan 19, 2009
My problem with AddNew. It really is somewhat simple, but I can't figure out the solution. I have a form where I show a list of my rows with a given a table. The user can then select a row and press clone, which then will try to make a copy of that row.
Here is a snippet:
Dim rowToCopy As cmaDBDataSet.cmaPropertyRecRow
Dim originalID, newID As Integer
rowToCopy = CType(CType(Me.CmaPropertyRecBindingSource.Current, DataRowView).Row, cmaDBDataSet.cmaPropertyRecRow)
originalID = rowToCopy.id ' id of row to be copied
[CODE]...
.... and continue to copy the rest of the data to the newrow...One of the items in the row is obviously a primary key called id. I can not copy this data since I am creating a new row. My problem is, how do I set that value!? or atleast retrieve the value for the newly added table. I need that value so that I can call another form to actually allow the user to modify this newly cloned data. I tried using EndEdit, UpdateAll, no worky. THen I thought I could assume that the newly added row would go at the end of the table so I used MovedLast then got the currentRow id from there... That worked well until we did some deletes within the table.

How to hide or show rows in a table layout panel.
As I used rowstyle property and it works
But the issues are
1) It works very slow
2) It seems as form is vibrating and lightning behind the panel when rows are hiding or showing(jerky motion of hiding or showing)
I also used the control .visible property for each control of the row but it also make same problem of being slow

I have a Windows application form. Directly on the form I have a lable ("Customer Names"), a ComboBox (pulling actually names from a database) , and a Buton to add a customer to the database if i choose. Additionally I have ControlTab(3 tabs) that has "fields" and its own Buttons to insert data into a different table. The first 2 tabs have textBoxes, which are completely functional, but the 3rd tab has a "DataGridView"

I have Dataset ds filled up with values Until now I was displaying values in GridView. Now I want that all the rows should be columns and columns should be rows.I have 2 options: Either 1 I can directly convert grid to columns and display it, or 2 I can convert the GridView to html and then write loops to convert. I was trying the 2nd option but I cant figure out how I should do that.[code]With this code I am still getting same as GridView. Please help me for converting rows to columns and vice versa.

I have created a form which has two things a list box and a button which is labeled "Input Values"The user should click "Input Values" and a new form will appear. This new form will ask the user to enter 10 values into a textbox and click ok after each value. These values are to be stored in an array and displayed in the listbox on the previous form.I am having trouble getting the values of the user to store into my array and displaying into a list box. I have this so far.

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

I am using MS-SQL and I am trying to write a query which fetches rows from the master table and related rows from the detail table. Now, the thing I want is that it must only fetch the first row from the master table and related field from the detail tables should be blank in that first row, now if there are related rows found in the detail tables, they must be shown in the separate rows. I have been trying using the following query but it is not giving the desired result.

I've got a table in an SQL server that often has large amounts of data imported into it via an automated process - the problem is that a lot of the data that gets imported is a duplicate of data that is already in there (for example if we have a customer in there called Mr Customer Ltd, a duplicate with a slightly different name could get imported, like Mr.Customer Ltd).
So I am using the Fuzzy Logic class that Wild Bill put in the CodeBank to find names that are similar and then highlight these items. The thing is that the target table that the imported data ends up in has several thousand rows and the table that contains the data to be imported often contains several thousand rows as well, so I'm trying to decide how to do this. Obviously reading both tables into memory is not an option as it will consume too much memory on the client PC that is running this app. So this is what I am doing at the moment:
1. Read the table that contains data to be imported into a DataTable in memory
2. Open a connection to the target table and use the SQLDataReader to start to loop through it
3. In this loop, for each row that the data reader reads I then loop through the entire set of rows in the DataTable and run this fuzzy logic method that compares the account name from the current row in the datatable loop to the account name in the row that the datareader is currently on.(there is also a Thread.Sleep(1) after each row is processed to prevent the process from eating up 100% of the CPU while it runs)

I fill the DGV by looping through a dataset and adding a DGV row for each datarow. After this the DGV.RowCount = DataSet.Rows.Count. Funny thing is that the DGV shows only a part of it (19 of 2448 in my example). After some testing I figured out that the rows show up if I change the Window size a bit.So now I use a work-around by including the following code after I've filled the DGV:[code]

I need a help with showing/hiding rows in datagridview by setting the trackbar value. The below example works if there are not too much rows. If there are greater number of rows then after you change a value of trackbar you must wait for a few seconds for the datagridview to redraw and only then you can use trackbar again.Apparently I must use multithreading to achieve what I want: when I use trackbar, datagridview starts to redraw, but if I use trackbar again before datagridview finishes redrawing, it immediately stops redrawing according to previous trackbar value and starts to redraw from the beginning according to current trackbar value. That way trackbar will never be frozzen (stuck, unusable...).I tried with backgroundworker but got error "Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on." I have old and slow computer. If you have new and fast computer maybe you wont experience what I'm describing here so try to increase number of added rows in line 'For i As Integer = 1 To 5000' (I added 5000 rows here) - and if you have even older and slower computer than you will have to decrease this value or you will have to wait to long after you drag the thumb in trackbar.

I have a table in where I am trying to delete all the rows except for the first. I did manage to come up with the code following:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim dtRemoveRows As DataTable =
[Code]....
In review, this code sort of holds the first row and clears the remaining rows. However, when I exit and reopen the program the rows return. So in other words, I want the rows to get permently deleted. I have searched and cannot find a solution to permenly delete all rows without deleting the first row.

I need to take rows that I have made from a previous table and somehow reuse them in another table that I am going to make, and I cant figure out how to. Its not necessarily the rows that's tricking me but its what the column name is looking for. Its looking for a string and I don't know how to make it so VB spits out what I want it to.

I have a bound data table bound to a datagridview. Every time the user clicks on a link to "add" a transaction, it's supposed to write to the register.
It does, but it writes it to the first line, and then overwrites it each additional click. How do I append, autoincrement, sequentially go to the next line?[code]....
