How To Add DateTime Data Filter
May 6, 2012
I have a code which can get the MAX value of distinct "SYSID" field. Now, I plan to add a data filtering by time - Start and End time. I have tried but getting all sorts of error and can't get what I'm after for. So the program should do the data filtering (data >=starttime and data <=endtime) first before getting the max value of "SYSID"
Below is my
Private Sub Get_Max()
Dim ci As New CultureInfo(CultureInfo.InvariantCulture.LCID, True)
Dim dtfi As New DateTimeFormatInfo()
dtfi.ShortDatePattern = "MM/dd/yyyy"
dtfi.ShortTimePattern = "hh.mm.ss"

I'm using EPPlus to create Excel reports. Now i'm trying to create a Pivot with a DateTime PageField, so that the user can filter the period he want to see by himself. But although i can filter this for year,month or days in the according data worksheet by default, i don't get it working in the Pivot.
Here is what i have:
Dim wsPivot = excel.Workbook.Worksheets.Add("Pivot")
Dim wsData = excel.Workbook.Worksheets.Add("Data")
Dim source = workSheet.GetDataSource

I'm trying to create a Windows form application which uses a few data grid views to pull data back from a SQL Server database. I've managed to get the data back okay from the tables but what I want to do is filter that data dynamically based on values input by the user from a combo box and a date time picker. Each of the data grids display production data for a machine but the combo box and date time picker will allow the data to be filtered by shift and date respectively - how to I pass the values of these to the SQL query returning the data?

I want to filter data on the textchange event on listview so I use dataview to filter data. Issue in the below code is, I use dataview inside for each so that it checks only one condition that is last value only it takes, I want to check value in s1 with dataview and remaining value should bind with listview. E.g.: if I type an in textbox it should list all the item values starting with an value like anandha kumar, anna etc. Suppose I keep the value anandha kumar and anna in array s1. I should list all other values expect the array values like antony etc... in listview.
protected void TextBox1_TextChanged(object sender, EventArgs e) {
dvProducts = (DataView)Session["ListViewItems"];
string serachText = EscapeLikeValue(TextBox1.Text);
string lvValues = hdRetailCustomerGroup.Value;
string trim = lvValues.Replace(" ", "");

I have an arraylist that holds a subset of names found in my database. I need to write a query to get a count of the people in the arraylist for certain sections i.e. There is a field "City" in my database from the people in the arraylist of names I want to know how many of them live in Chicago, how many live in New York etc.
how I might set up an sql statement to handle this. I think somehow I have to pass the subset of names to sql somehow.
Here is a sample how I am writing my sql in my code
Public Shared Function GetCAData(ByVal employeeName As String) As DataTable
Dim strQuery As String = "SELECT EMPLID, EMPLNME, DISP_TYPE, BEGIN_DTE FROM Corr WHERE (EMPLNME = @name)"
[Code]....
I need a way to create a function using your sql statement to return a datatable object of names and the parameters would be city, and the List of names.
The above example isnt the sql I am looking for its just a skeleton of what the function would look like that I want to create.
So then you would use the function by iterating through all the cities passing in the same set of names each time in the fron end.

I have an idea, but i am not sure how to implement it with code.I have an application where a user can view current bookings for rooms.I have two datagridview controls, the first one shows the rooms and the second shows all my current bookings.What I want to be able to do or more the user, is click on a room and the current bookings for that room (datagridview1) to be shown in (datagridview2).What I think I need to do is apply a filter and a sort in a sub routine, then link my tables with a binding source.

Everything works as it should exepct that the seconds part of a datetime column is missing when the code is run.The odd thing about this is that the seconds part appears when i execute the query in query builder.[code]

Which method would be fastest / most efficient?
A) Read all data (822 rows) including those I do not need then filter / output those I do
B) 3 Round trips to the db using params filled via the last query to select only the data I need

I have a CombBox and a data grid view on a form, when the form loads, the data grid view is loaded with data from the database. I want to filter that data with a selection from the combobox (which is loaded with data from another database). The code i have is as follows:
ContactsBindingSource.Filter = "Company Like '%" & Me.cmbSelectCompany.Text & "%'"but when I select an option from the drop down list the DGV gets cleared down as if my selection has no equivilant data in teh DGV.

I'm using a dataview and bind it to data grid view. Currently my data is shown nicely at data grid view, and I successfully added filter: itemDataView.RowFilter = "item_id LIKE '" & Me.txtItem_ID.Text & while itemDataView is my dataview, and txtItem_ID is a text box to allow my users entering filter parameter.
This code runs nicely, but the problem occurs when a user enter special character(s) like an apostrophe (single quote " ' ") or an opening square bracket " [ ". Is there any way so that I can escape this characters? Currently I'm replacing each one of them using text.Replace()
itemDataView.RowFilter = "item_id LIKE '" & Me.txtItem_ID.Text.Replace("'", "''").Replace("[", "'[") & "'"
