i am developing a software using microsoft visual studio basic 2010. I set up a connection string to my server and take the data from there. I am using gridcontrolview and put my "product" table in here. It contain 4 column: systemid, system, actualid, description. I want to display only system column (it's easy, just hide the others column) But, In "system" column, there are a lot of similar data, i want to display only distinct data from this column in the grid
example, the column consist: STSTEM
topaz
topaz

I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")
Dim*SaveTextFile*As*String*= IO.Path.Combine("C:Test2.txt")

I am using the following code for a combobox to display a series of codes depending upon the value entered in combobox1. This works fine except the column being displayed contains a 6 character field (A99999) and I would like to display only the last 5 numeric characters rather than the whole column. otherwise I shall have to add an additional field into the table which contains just the numeric part of the code.
Dim LowestVal As String
LowestVal = ComboBox1.Text & "00000"
Dim HighestVal As String

I am making a combobox from my data source. Basically, This is a projects form and the user needs to select the the primary contact which is contrained by the customer id (GETbyCustomerID) set in another field. I have it working... mostly except the combobox only displays the contact ID which is completely useless to the user. I need to know how to display the First and Last name (both are seperate columns in the table).

i have a windows form with controls that i have associated with a database. all controls display the correct value but i'm having problem with 1 of them. i have added a listbox (not even sure if that is the correct control for that) where i want to display the list of the first column from the database. i want the listbox to display all items so when i click on one item, the other controls will be updated with the information about that item. i know the connection to the DB works because all other controls have the values from the first item. only the listbox is empty.

At runtime, I am adding a DataGridView to a windows form. The final column is a DataGridViewImageColumn:
Dim InfoIconColumn As New DataGridViewImageColumn
MyDataGridView.Columns.Insert(MyDataGridView.Columns.Count, InfoIconColumn)
Adding the following code will get my Information Icon (bitmap) to display in each of the column cells but NOT the column header:
Dim InfoIcon As New Bitmap("C:MyPathInfoIcon.bmp")
InfoIconColumn.Image = InfoIcon
Also, it is worth noting that the image displays 'perfectly' in the cells i.e. it is sized correctly to fit the cell.
However, I cannot find a way to add the same image to the column header cell. After some googling I used the following code which placed the image in the header cell but left me with two problems:
The image did not 'auto-size' to the column headercell in the same way it did when added to the column cells. The image was slightly larger and blurred.
By using the _CellPainting event slowed down performance i.e. when hovering over the DataGridView to highlight the selected row the highlighting lagged behind where my mouse was placed.
Here is the code:
[Code]...
Does anybody know of a way to solve my problem and get a nicely sized, sharp image into a DataGridViewImageColumn headercell at runtime?

I have a DGV which is part of an inventory system. I have several columns but the ones i need to resolve are Quantity, Name and Plural Name. essentially if quantity is 1 i need to display the Name data if greater than one the plural data. Is this possible? would i need to resolve this earlier in the process (the data is extracted from an xml file using LINQ to bind it to a rowObject) or can i do this with the completed dataset, say by hiding the Name and Plural Name colums and creating a custom column? ideally i would like to keep the data untouched.

I am having trouble in allowing the user to select the row in the datagridview.
I managed to include the checkbox column in the datagridview but i do not know how to wrte the code such that when the user wants to update or edit the data in the checked row, he just have to check the affected rows checkbox, can be one or many, and then click on ok button, which will then lead him to the data updater form, allowing him to update the data.
Currently i have the below code which can populate the checkboxclumn only.
dbProvider = "PROVIDER=MICROSOFT.Jet.OLEDB.4.0;"
dbSource = "Data Source = '" & Form1.TextBox8.Text & "'"
con.ConnectionString = dbProvider & dbSource

I have to implement a column (TransactionCompleted) which will only hold two states Yes/No. I am using SQL Express and wonder which would be the best DataType to go for that column, if I prefer to display the data in a DataGridView column as CheckBoxes later in my application?
