Displaying Information In A Grid
May 13, 2009
I am working on a Windows Forms Application and I have got stuck and wondered if anyone can provide some much needed direction. [Code] The user makes a selection of, say region, and then a DB layer sends back some linq IQueriable(of sometype) for a particular month. I wanted to add a month column each time they select a month.
I can't seem to do this too well with a datagridview, I have tried making a class that holds the measure as string and value as decimal and then create a list of these to bind but then if I add a new one I have problems as it just overwrits the origional one. I could just place a series of textboxes and fill them as I go but this seems like it is a problem waiting to happen kind of way. What I really need is some sort of grid that is expandable.

I am working on a program in VB 2008 that will generate a due list. What I need to do is look in a dataset for customers that are due this month and display it in a grid that can be orded by their city. I know how to do a query to that dataset and find the appointments, I do not know how to display the information in a grid from for sorting.

I started programming in VB many moons ago, but I put it down about a year ago. I picked back up a project I was working on a few years ago and Visual Studio 2008 Pro had to convert it. It seemed to work just fine but I wanted to make it "look .NETish", so I simply copied all the controls and code into a new project.The new project won't display information stored in static arrays on a Rich Text Box. The arrays are declared public in a code.vb file and the array is populated in the load event for the main form.I've tried inserting a "test" button to see if I could somehow get it to display trying a few different things. Essentially:
Private Sub cmdTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdTest.Click
Dim test As String = Gems(0)
[code].....
Has array conventions changed or something in the past year or so? How do I extract the information contained in Gems() that I have so maticulously entered so long ago

I remember using a one liner, something along the lines of AxWindowsMediaPlayer.currentMedia.Artist or something similar, that required no complex processing of the file, to display artist, album and song title. Using the WMP 11 control. It's been a while since i needed to use that and i've lost it.
Was wondering if anyone knew what that was, and if im mistaken, what easy method, without processing strings, files etc. there is in getting ID3 tags.
Im using Visual Basic Express 2008

I have 5 textboxes embedded in a datagrid that require a date format (mm/dd/yy), but can be left empty if user doesn't have date. User can poplutes these textboxes for multiple records and hit submit button. On the submit i loop through the grid. If dates are populated AND they are in the correct format then I call a stored procedure that inserts the record into a table. If any of the dates that are populated in the textbox is not a date or in the incorrect format I need to display error message in a label. I got all this to work, but if it throws error message all the data in the grid is wiped out.
How can i keep data in each textbox and still display the error message?

I need to use an array at any part of the project. It has been suggested to me to build an array and show its result in a combobox. Instead of having an input textbox, i will have a combobox which will display 10 common names which are kept in the array.
'Defines the array Names
Dim names(9) As String
'Defines the array's fields[code]......

I have a form set up for drag and drop. The dragging and dropping is working nicely, as it allows the user to put a pair of dots onto a rectangle, which is exactly what it is supposed to do. However, I would like to give them some information about where they are dropping the points. My first thought was that I could use a tooltip. However, it appears that tooltips are not displayed during drag events. The tooltip works well, and is showing what I want, once I have released the mouse button, but not before then. The only other alternative I can think of, and it is not a very appealing alternative, is that I have some labels elsewhere on the form to display the information.

I am using a data grid view to display information from a database and I can't get it to update correctly.I can see the data from the database but when I change information and save it it changes the entire column's information. My rows need to have different values in the same column so this is a problem.Here is my code so far, what the program does is makes a list of transactions that are entered.

This project is based on a MUD, or at least originates from playing them. I have an ascii map where each character represents a type of terrain. I have found code for reading one line at a time, but I need to not only dictate which line to be read, but how many characters in to the line to read. Basically trying to make a grid/coordinate system, where I can tell it my location is 4, 7 and the program will read the fourth line, seventh character.

I have been coding an application for a LeaderBoard for a game. I have all the Login sorted using Mysql and even have all the Account infomation displaying in lables etc. for account info form. Now I am trying to UPDATE information and this is how I was trying to do this...
Dim UpdateInfo As New MySqlDataAdapter
Dim mycommand As New MySqlCommand()
Dim mydata As MySqlDataReader
Dim query = "UPDATE Login SET Pword = '" + UpdateTxtBox.Text + "' WHERE Uname = " + Login.Uname
mycommand.Connection = conn
mycommand.CommandText = query
UpdateInfo.SelectCommand = mycommand
mydata = mycommand.ExecuteReader()
But comes back with an Error saying... Unknown column 'username here' in 'where clause'. Now the username is in the database as I have just logged in with it and I am taking it I have the Query wrong somewhere.

I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.

I have more than 30,000 rows in a table. It takes a lot of time to load all the data in the gridview. So I want to display 100 rows at a time. When I click next page button, another 100 rows should be displayed. When I click previous page button, previous 100 rows should be displayed. If I type page 5 in a text box, then I want to jump over to the 5th lot of rows.
I also want to display how many pages there will be. Can we implement this concept in vb.net [winform] gridview. I am using database PostgreSQL.

winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :
[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

need to have a summation field in each row of a grid in visual basic. Each row needs to calculate the remaining quantity of its row and all other rows beneath it. Thus the subtotal field in the 1st row would equal the sum of the shown quantity field for the entire grid.The next row would include its value and all those beneath it. Its subtotal value would be less than the subtotal of the row above it (by the quantity value of the 1st row). My code for the grid is very simple I just can't figure out how to add this iteration.
