View 1 RepliesI have found some code using google for listview printing. I modified the code base on my needs. I have some problem if the list view more than one pages. It will not stop counting "Generating Previews" of my document. If I press the cancel it was display the data in multiple pages but the same content.
Here is the code
Public Sub pd_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs)
Dim pd As New PrintDocument
Dim CurrRow As Integer = 0
Dim Ratio As Single = 0

View 1 RepliesI am primarily a web developer, mostly working with PHP, MySQL, and JavaScript. I was recently contacted by a local Sheriff's Office (small town word of mouth, nerds are always needed) to digitize a 4 page monstrosity of a form... because nobody could read the handwriting of the deputies.The catch here is that this is a small town department and, while they are fancy enough to carry computers in the field, they are not connected to the Internet. Visual Basic was the first solution that came to mind and I have been scrambling to learn the basics. I am confident in my ability to organize the content of the form and perform any necessary validation but I am unsure where to begin in terms of storing each report locally (database) and printing the end result.
Another matter that makes things complicated is the fact that they want the end result to look exactly the same as the original form, only typed instead of hand written.So, to sum things up, here are the questions I have:there seem to be several options for databases in VB 2010 Express. What is the best option for LOCAL storage of records?It looks as though the best way to format the form the exact way they want it to look with populated data would be to create a form within the application with just this content on it. Is this the best solution or might there be a better way - possibly outputting to another file? And if the data is put on another form, how would I go about printing it?
I am current upgrading some of the functions on an inventory system. Current system accepts manual data input from the user and stores them in a SQL database.One of the inputs is control number which is a primary key in one of our table so it needs to be unique. Since it is manually entered into the system, we have to keep track of all of control numbers so there is no redundant control number which is difficult since we have hundreds of items with unique control number that are entered into the system everyday.Yes, it is waste of time.So I want our newly upgraded system to have a function where the control number is automatically generated so the control numbers are controled by the system. I know there something similar in MS Access 2007 but I cant seem to find it on Visual Studio. [code]

View 2 RepliesMajor problems with the Schema. I am using the DataGrid and not the VB Express 2010 DataGridView. Using code to make a new DataSet and DataView. What is confusing me is when adding Items after right clicking the application in the Solution Explorer, the add items shows DataSet, Xml To Schema, and Xml File. It is obvious that I don't know how to generate an xsd file that I can read into a code generated DataSet. If someone is familiar with xml and VB Express2010. how to generate an xsd file using DataGrid instead of DataGridView that I can read into a code generated DataSet?

The only way I know how to put an item in a list view is to make a new item, which is the first column, then add a sub item for the columns after that and the item is placed in the row.For this Project I am wondering if there is a way to easily add items to individual cells, based on the column and group, not add items in a row at a time.
Something like the following image is what I need to do with code. To get this I manually added the items in the designer. But the logic bases where to put the class on the other classes in that time block (Mon at 8-1030am is one block). However if we have to add them a row at a time it throws off our logic and thought process.
How can I get items in listview? I know how to get the current item if selected but Im trying to put it in a loop where i need to get my three row items there.

Dim a As Integer = 0

I have a system which stores fee's paid for a youth teams players.A textfile stores:player name|trainingsessionsattended|amountpaidin..Each line is a new player's entry.I need to make a form that allows the user to input the amount paid by each player at the end of a training session.I did think of doing a single dropdown box and allowing the user to select a user and enter how much he/she paid and entering each players fee's one by one. But this is not practical, considering there are 20 players, this may take a while.I thought of having a listview with every players name and then using this to add the players fee's but am not entirely sure how to go about this.

I'm running it under a BGW and it works fine but is there anyone who can comment on it and make my code a bit better. I've a background worker and I am running it again and again on the RunWorkerCompleted like this
VB

BGW.RunWorkerAsync()
End Sub
Is it bad coding or is there any alternative to run it?
I need a control that will allow me to do a few things.
The control should be similar to Listview in detail mode, in that it lets me show numerous rows, each row with multiple columns. However, I want it editable in place... that is, the user can (if I let him) click on a column and change what is stored there.
The next thing I need to do is set a graphic in one column, text in another, a playback controller in a third, and a trackbar control in the fourth. Every row will look like that.
The final thing I need to do is be able to control how a row is painted... either the entire line or by putting a graphic image (like a button) in a column when it is not being edited.
Barring all of that, I can put all the controls I need into a single user control, then I need some listview-like control that will allow me to add that control to it.. and have it be operational.
I am writing a windows forms application in Visual Studio 10 on Windows 7.
I am facing little trouble while deleting the listview subitems. I am also using try and catch method to handle the execption but i am keep on getting it.

If lviSubitem = "Error" Then
lvi.Remove()

Ok, I found some code online on how to do this, but they only compare the Listview.item.text, and they don't care what is in the entire ListViewItem. Is there any code to remove duplicates in a ListView that checks to see if all the subitems are the same as well and THEN removes the entry? [Code]

I've used the same method to add items to a listview before but for some reason they're not showing, I even just tried a test:
Dim row As New ListViewItem
row.Text = "test"
row.SubItems.Add("test")
lstvwHistory.Items.Add(row)
in the load and that doesn't show up.Here is what I am trying:

I walked through the code having a message box pop up every time an item was added with the count and it goes up as it should, nothing throws an error, and the item has all the correct parameters. I commented out the making a new group and just plain add the items and it still didn't show. I tried the lstView in all the kinds of views (detail, small icon, etc.)
I want to just sort one column in a listview control. Is this possible or are all the columns tied together?
