Passing SQL Output Statement?

Apr 19, 2010

Im creating a quick utility program that deletes any invalid data within my database. This works fine and im happy with it. I was thinking why not backup this table first before modifying the bad data, easy! I was Wrong. Seems to be a problem with my sql command and the way vb passes it.

Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
con.ConnectionString = "Provider=ASAProv;" & "Data source=MY_DSN;UID=dba;PWD=sql"

Use And If Statement To Output To 2 Text Boxes?

Jun 22, 2012

I had a small query relating to using an If statement.

Is there a short / easy way to populate 2 or more text boxes with different text if an if statement is true.

So.

If A = 1 then TextBox1 = "AA" and TextBox2 = "BB" etc

I've tried doing it with 'And' '&' but just keep getting a 'False' appear in my Textbox1 and nothing in the 2nd or 3rd.

.net - Will Sqldatareader With Using Statement Ever Return An Output Parameter

Aug 21, 2011

Here's a simple code snippet of a larger function as an example.

Using conn as New SqlConnection("conn string")
Using find as new SqlCommand("ExampleProc",conn)
Dim rParam as new SqlParameter("@RESULT",SqlDbType.Int)

[code]....

I know the Output parameter is returned after the SqlDataReader is closed. From what I think I know, the Using statement will call .Dispose on the SqlDataReader, so will that basically wipe out the Output parameter? If so, what is the best method to call a SqlDataReader that also contains Output parameters that closes and disposes everything correctly? Let me add that based on what I've read you only have access to the Output parameter using a SqlDataReader after you call .Close on the SqlDataReader.

VS 2008 Using Output Of Calendar Control In SQL Statement?

May 13, 2009

trying to write a simple app that queries an access DB based on date .. the SQL looks like this and works fine with a date hard wired into the select:

SELECT Terminal_ID, SUM(Transaction_Quantity) AS Total
FROM tblTransaction
WHERE (TransactionType_ID = 3) AND (Transaction_DateTime > #1/1/2009#)
GROUP BY Terminal_ID

On the main form I have a monthcalendar control named 'FromDate' and a DataGridView control that shows the SQL results.

How do I get the user's selected date incorporated into the SQL statement that returns the results in the datagrid?

Something like:

WHERE (TransactionType_ID = 3) AND (Transaction_DateTime > Fromdate)

...but obviously there's much more to it.

Passing List Of (integer) To Select Statement?

Mar 27, 2012

I have a function that returns a Datatable. I am passing a list of Integer as an argument. Then I thought tis would work.

Public Function GetEventsByEventType(ByVal EventType As List(Of Integer), ByVal DayInterval As Integer) As DataTable
Using con As New MySqlConnection(strCon)

[Code]...

as you can see. I use string.join to convert the list of integer to something like this. '1,2,3'. Problem is that is read as a string so i get the incorrect results. I need to have where EventType IN(1,2,3).

.net - Why Only Getting One Output Value (and No Debug Output) From This Code?

Jun 14, 2012

I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.

Module Module1
Dim selectednames As String = ""
Dim index As Short = 0
Dim inarray As Boolean = False

[code]....

Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is

For x = 0 To totalnames - 1
Debug.Print("namesarray(" & x & ") = " & namesarray(x))
Next

not giving me a debug output?

If <expression> Then <statement [:statement]> Else [statements] In Concrete Form?

Jan 1, 2010

I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this

If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?

Break Up The Code In A Method Body Into Statement By Statement Symbols/"tokens"?

Apr 22, 2011

I'm writing something that will examine a function and rewrite that function in another language so basically if inside my function F1, i have this line of code var x=a.b(1) how do i break up the function body into symbols or "tokens"?I've searched around and thought that stuff in System.Reflection.MethodInfo.GetMethodBody would do the trick however that class doesn't seem to be able to have the capabilities to do what i want..dit 2:basically what I'm trying to do is to write a program in c#/vb and when i hit F5 a serializer function will (use reflection and) take the entire program (all the classes in that program) and serialize it into a single javascript file. of course javascript doesn't have the .net library so basically the C#/VB program will limit its use of classes to the .js library (which is a library written in c#/vb emulating the framework of javascript objects)

Exceptions - Can The "Throw" Statement Exist In A Block With No Try/catch Statement

Oct 5, 2009

how to use them then before, but am still a little confused with a few aspects. Here goes:

1.) Lets say you have a method that checks for a certain condition(s) and if it fails Throws an exception. Does it have to be in a try/catch block? Meaning can the "Throw" statement exist in a block with no try/catch statement?

2.) Now lets say we have a method that has a try catch block and in it there is a throw statement. When the throw statement is executed does it first try to find an appropriate catch block in the same method or does it immediately go back to the calling method without looking at the catch statements in the current method where the exception was thrown?

3.) I created a custom exception class that inherits from ApplicationException. Next I created a method which has a catch block that catches this type of exception and does some action. Is the System(i.e CLR) smart enough to throw an exception of this type, or does it only throw exceptions from SystemException?

4.) I know that some people are more liberal in their use of exceptions and others use it more sparingly when truly strange stuff happen like the DB going down. I am writing code where I am getting some info back from the database, converting it and then storing it. Sometimes there might be data that comes back from the database and other times the field is empty and the Null value comes back. Therefore in the instances where Null comes back from the database I should not convert the value to anything, since I will get an error. What should I do in this situation? Should I let the CLR throw the exception when it goes to convert the Null value or should I check for the Null value and if it exists not convert?

5.) In general when I throw exceptions, is it sensible to only throw exceptions of the type Application Exception or are there instances where the programmer throws exceptions of the type SystemException?

Make A 'like' Statement Or Use Some Kind Of Wildcard To Make The Statement Not Case Sensitive?

Jul 11, 2010

I'm building a listview search feature in my app. (See the code below). It works really well, except if you search "T" then the code removes all items, if you search "t" then it removes every item except for those starting with "t". Is there any way to make a 'like' statement, or use some kind of wildcard to make the statement not case sensitive?

For Each itm As ListViewItem In ListView2.Items
If itm.Text Like TextBox1.Text & "*" Or itm.SubItems.Item(1).Text Like TextBox1.Text & "*" Then
