Running A Query On Access From VB, Passing Variable Or Function As Query Parameter

Apr 7, 2012

I am trying to run a query an Access db from VB. The general query which I want to run is

SELECT * FROM Patient WHERE Patient.PatientID = ?
or SELECT * FROM Patient WHERE Patient.PatientLname = ?


I tried using an input box which captured the user input and pass that variable to the query, but that failed. Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function: [Code]

Passing Date Parameter To DataTable.Select() Method

Apr 9, 2009

Jst recently i came across the select() method of data table and felli n love with it instantaneously.

Basically I want query the data table on a date field, unfortunately the format of the date string returned from y database in to data-table and the date string i'm passing as inputs are different.

How can i make sure that the data is compared irrespective of the formats ? Can I use something like SqlParameters whoes data type is date for comparison ??

dim dat as date = "#1/3/2009#"
dt.select("StzDate ='" & dat "'")
entry in datateable dt : StzDate : 3/1/2009 12:00:000
Am I do'in something wrong ??

Also, can anyone redirect me to some site where I can learn a bit more about passing parameters to the select statement,etc...

Sql - Passing Comma Delimited List As Parameter To IN Clause For Db2 Query Using Designer In 2008?

Mar 26, 2009

I want to pass a comma delemited list of values as a parameter to a query I'm building using the designer in Visual Studio 2008 based on some strongly typed DAL tutorials I was going through. The query is going against a DB2 database. Here's what I want to do:

select * from prices where customer in(?)

It works fine win I pass in 123456 as ?But fails when I pass in '123456' (it is a char field so I don't know why this doesn't work; it must be adding these behind the scenes) or 123456, 123457 or '123456', '123457' I'm adding this page to a portal where all the data access is being done based on the DAL designer model with a BLL that calls it so I wanted to do it this way for consistency.

Access Database And Using A Parameter Query With The LIKE Operator To Return All Rows That Match Query?

Passing An Event As A Parameter

Jun 10, 2011

I need to pass an event as a parameter to a function and I'm wondering if there is any way of doing this.The reason why I need to do this is because I have a sequence of two lines of code that is littered all over my program, where I dynamically remove the handler to an event, then set the handler again. I'm doing this for several different events and event handlers, so I've decided to write a function that does this. As an example, let's say I have a combobox in my code called combobox1, and I have the handler called indexChangedHandler. In several places of my code, I have the following two lines:[code]Now, I don't want to keep on repeating the above two lines of code (or similar) all over my program, so I'm looking for a way to do this:[code]So far, the "evt as Event" part of the argument of the setHandler function is giving an error. Any ideas on the right way to do this will be very welcomed.

Passing An Event As A Parameter?

Nov 10, 2010

I need to pass an event as a parameter to a function and I'm wondering if there is any way of doing this.

The reason why I need to do this is because I have a sequence of two lines of code that is littered all over my program, where I dynamically remove the handler to an event, then set the handler again. I'm doing this for several different events and event handlers, so I've decided to write a function that does this.

As an example, let's say I have a combobox in my code called combobox1, and I have the handler called indexChangedHandler. In several places of my code, I have the following two lines:

RemoveHandler combobox1.SelectedIndexChanged, AddressOf indexChangedHandler
AddHandler combobox1.SelectedIndexChanged, AddressOf indexChangedHandler

Now, I don't want to keep on repeating the above two lines of code (or similar) all over my program, so I'm looking for a way to do this:

Private Sub setHandler(evt As Event, hndler As eventhandler)
RemoveHandler evt, hndler
AddHandler evt, hndler
End Sub

so that everywhere where those two lines of code(or similar) occur in my program, I can just replace them with:

setHandler(combobox1.SelectedIndexChanged, AddressOf indexChangedHandler)

So far, the "evt as Event" part of the argument of the setHandler function is giving an error.

P.S I've asked this question on a couple of other forums and keep getting asked why I would want to set the handler immediately after removing it. The reason is because dynamically adding an event handler n-times causes the handler to be executed n-times when the event occurs. To avoid this, i.e to ensure that the handler is executed just once when the event occurs, I first remove the handler each time I want to add the handler dynamically.

You might be asking why the handler would be added several times in the first place... The reason is because I add the handler only after a particular event, say E1, in my form has occured (I add the handler within the handler of event E1). And event E1 can occur several times within my form. If I do not remove the handler each time before adding it again, the handler gets added and thus executed several times.

Whatever the case, the processing occuring within the function is not of ultimate importance to me at this time, but rather just the means of passing an event as a parameter.

Simple Parameter Passing To Oracle DB?

May 1, 2012

Im using a datatable and i am trying to do a insert statement into an oracle database by passing selected values from the datatable to the insert statement via parameters. I'v traced the parameter collection and it has the correct number of parameters to be passed but it is giving me an error saying a value being passed in is null but it is not, during debug you can clearly see the value of the parameter is not null.

Dim FuelInsert As String = "INSERT INTO table (COMPANY, TRAN_DATE, GAS_GALLONS,DSL_GALLONS,DEF_GALLONS,KER_GALLONS,E85_GALLONS,DDS_GALLONS,WDS_GALLONS)" _
+ "VALUES(:Company, :Trans_Date, :Gas_Gallons, sl_Gallons, ef_Gallons, :Ker_Gallons, :E85_Gallons, ds_Gallons, :Wds_Gallons)"

[code]....

I just wanted to know if there was a easier way of creating the parameters or if i am missing something simple that causing the values of the parameters being passed to get mixed up. The code retrieves the values i need and builds the parameter collection of 0-8 nodes which is correct.

VS 02/03 Crystal Reports Parameter Passing?

I seem to be passing the parameter to the report (I placed the parameter field itself on the report to verify this) but it does grab any information based on this parameter.

VS 2005 Passing A Parameter With AddHandler?

Oct 2, 2009

From what I understand, when you use AddHandler you're not actually calling a Sub, so you can't pass a parameter. I'm confused on what to do though about this. I've just populated a DataGridView and added a button to it in the codebehind. I'm then using an AddHandler to add a click event to the button. So when I get to the click event, I need to be able to access to the datagridview because clicking the button takes data from the datagridview and loads it into excel. What would I do about this. This is my Method where DataGridView was just populated

Dim btn As New Button
btn.Name = dgv.ToString()
btn.Location = New Point(0, 0)

.net - Passing A Method (that Returns A Value) As A Parameter A Bad Thing?

May 21, 2012

So for instance I have this method: LoadFunkyInfo(byval funkyData as string) And I pass it something like this:

LoadFunkyInfo(giantTable.Rows.Item(0).Item("blahName")). Should I do this instead?

dim foo as string = giantTable.Rows.Item(0).Item("blahName")
LoadFunkyInfo(foo)

I read somewhere long ago, that it's better to assign the method to a variable and pass that variable to a method, as opposed to passing the method as a parameter. Is that still true? Or true at all?
