i have a form with 3 combo boxes. The value of the combo boxes generates a sql query with 3 parameters. The sql generates a RDLC report.
For example:
Combox1 with values(v1,v2,v3,ALL)
Combox2 with values(v1,v2,ALL)
Combox3 with values(v1,v2,v3,4,ALL)
Me.ExampleTableAdapter.QueryWithParams(Me.ExampleDataSet.Table, Combobox1.SelectedIndex, Combobox2.SelectedIndex,Combobox1.SelectedIndex)
QueryWithParams:SELECT * FROM Table WHERE Column1=@c1 AND Column2=@c2 AND Column3=@c3 Ok the problem is when the selected value is ALL in the combo X, i cannot get the values because i must change the query and kick out the parameter.For example:If the combo1,combo2,combo3 have the values ALL. I don't need parameters.SELECT * FROM Table IF the combo1 is ALL.SELECT * FROM Table WHERE Column2=@c2 AND Column3=@c3 If combo1 and combo3 are ALL SELECT* FROM Table WHERE Column2=@c2 Then in code I look which is the selected value of the combo and upon it i do the query.Is there a way that i do this thing without generating all 8 types of queries?PS. I cannot use stored procedures because i'm using SQL Server Compact

I have a ListView with a CheckBox as one of the columns, bound to a boolean property of a custom object. I'm trying to figure out how to iterate through the items in the ListView and check all the checkboxes. What I have so far is below:
XAML:
<ListView x:Name="MyListView" DockPanel.Dock="Top" Height="275" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding}">
<ListView.View>

I am iteratiing through the info/test items and then want to iterate again through the test_properties, but I don't know how.the properties are never a fixed count, so it could have 1 property or 200.i need the type='" attribute and the value of the property.I use this so far:
Dim Xml_Document As XPathDocument = New XPathDocument("e: est.xml")
Dim Navigator As XPathNavigator = Xml_Document.CreateNavigator()
Dim ns As XmlNamespaceManager = New XmlNamespaceManager(Navigator.NameTable)[code].

I'm trying to create an export Excel/CSV function that will iterate through a custom object and first output the property names and then output the values. I want to use reflection only where necessary so I'm attempting to save the property names when I output the headers and then reuse them to print the values. Is this possible? I'm a little weary of using reflection in a loop but is there a better way?

I have a VB.NET project where I am able to iterate through the keys and values collections of a dictionary object using an index:
MyDictionary.Keys(idx)
MyDictionary.Values(idx)
When this code is taken from the test project and placed into the real project I get the following error:
'System.Collections.Generic.Dictionary(Of Double, String).KeyCollection' cannot be indexed because it has no default property.[code]...
In the line in sub search that says "dtf.Keys(idx) = 0" place your cursor after the right parenthesis and backspace you should get a tooltip that says, "<Extension> ElementAtOrDefault(index as Integer) as Double - index: the zero based element of the index to retrieve.

The user will click the book name in the combo box.
Note: The combo box is separate from datagridview . It is not part of datagridview columns.
Then the datagridview for Issuing books i.e. with the columns bid,bname,aname,data of issue,date of return should be displayed.
The row that will be displayed in datagridview is such that the bookname selected by user in the combo box should match with bname row .
On the same datagridview there will be button with name "Issue" so once it is clicked then this whole data of datagridview should get stored in the database table name "Issue" and get deleted from the databse table name "MBA"

I have the following problem: I have a combobox in my application. Sometimes the data inside are too wide to be displayed (see here). Is it possible to use tooltiptext to display the whole data line if the user stands on this line? Or perhaps sending the whole data to a right-click context menu? If so - how?

I have a table in my database that stores store items and their respective prices. I need a code which will, after displaying the items on listview, give the sum of their cost. i.e, when you use listvie1.items.count only gives you the count of the columns. I want to capture the total cost of loaded items, and display it in a textbox say textsum.

I have a ListView of 4 columns, one of which is a monetary value.I am trying to add these values of 'selected' rows. I can add ALL row's values - but not selected rows. The code that I use actually highlights all the rows that contain the string that is looked for but the result is not correct. Let me explain: Say I am looking for all the rows that contain the word "Special" and that it is in 4 rows. The 4 rows are highlighted but the result is the value of the first row highlighted multiplied by the number highlighted. In a Console.WriteLine I find that the same numberRow is shown 4 times. I can't work out how to get each row's value.[code]

I have a question about comparing values inside of a List. I have a single list of strings. Inside the list are multiple values. The values are arranged so they can be dumped into a spreadsheet.
Example:
Private ListOfStrings As New List(Of String)
ValueA(0), ValueB(1), ValueC(2) 'These three values are the same as the three values in the 4th "row" below
ValueD(3), ValueE(4), ValueF(5)
ValueG(6), ValueH(7), ValueI(8)
ValueA(9), ValueB(10), ValueC(11) 'These three values are the same as the three values in the 1st "row" above. Since this is a duplicate, I need to add a "count" of value 2 and then delete the values of this row from the List. Etc...
Each line above represents a "row" in a spreadsheet. All three values in each "row" have the potential to be the same. So, I need a way to A) Compare and count all of the common "rows" (using only the first value from each row) and B) If common "rows" occur, I need to delete all but one row from the List. ListOfStrings.Remove ?
