can u give me an example
i am a beginner of progamming and my english is normal so i dont know what to do
i want to have the words which the user types in text box when u type the programme shows all the words in a list box which starts with a
oh i am sorry about asking too many simple questions

I'm typing this directly so there may be some minor errors:
Dim someValue As String;
someValue = "%" & theTextBox.Text & "%"
myCommand.CommandText = "SELECT * FROM MyTable WHERE someColumn LIKE ?"
myCommand.Parameters.Add("?", someValue)
You may also wish to validate that the information the user has put in the text box is no longer than the length of the column, or check for any other conditions that make the value invalid before sending it to the database.

Hi ,
i am using the following code where "_sessionCalibrationSessionMasterDTO" and "_calibrationSessionMasterDTO" are of same kind of objects having different properties.
/*
Dim _calibrationSessionMasterDTOs As IList(Of CalibrationSessionMasterDTO) = New List(Of CalibrationSessionMasterDTO)
Dim _calibrationSessionMasterDTO As CalibrationSessionMasterDTO = DTOFactory.GetNewCalibrationSessionmasterDTO()
*/
One of the property is "NoofSessions" and other one is "SessionNumber"
First of all i'm checking the following condition and based on it i'm adding the "_calibrationSessionMasterDTO" into a list of same kind of object "_calibrationSessionMasterDTOs"
For _count As Integer = 1 To _sessionCalibrationSessionMasterDTO.NoofSessions
_calibrationSessionMasterDTO.SessionNumber = _count
_calibrationSessionMasterDTOs.Add(_calibrationSessionMasterDTO)
Next
Now the main problem is that for _count = 1 its working fine (there is no previous member) but as soon as _count increases the previous member of list _calibrationSessionMasterDTOs are updating with the latest one.
I have tried to initialize the object _calibrationSessionMasterDTO every time before adding it to the list but nothing happened.
I have also tried to insert these values instead of adding but nothing happened.
For example if _count = 1 and _calibrationSessionMasterDTO.SessionNumber = 1 then this loop is working fine.
but for _count=2 and _calibrationSessionMasterDTO.SessionNumber = 2 then
the previous value of _calibrationSessionMasterDTO.SessionNumber is updated by the latest one i.e. 1 is updated by 2...
please help me if any one having any idea...
If you can reply at earliest then it wud be gr8

Your new creating a new _calibrationSessionMasterDTO object before you add it to the collection. You're modifying the existing one and re-adding it over and over again. Change it to:
For _count As Integer = 1 To _sessionCalibrationSessionMasterDTO.NoofSessions
Dim newobj As CalibrationSessionMasterDTO = DTOFactory.GetNewCalibrationSessionmasterDTO()
newobj.SessionNumber = _count
_calibrationSessionMasterDTOs.Add(newobj)
Next

Thanks for the username and password! (You might want to remove those from future posts.)

You created an OleDbCommand object, but didn't give it an SQL statement to execute before you called ExecuteReader on it. The reader object won't work without it.

Anyone know of a control similar to a picture box but with clipping and stretching capability? I need a quick fix.
Thanks.

The PictureBox does do this, a little, but really, you need to draw your own bitmaps if you want full control, in your Paint handler.

I searched and looked around but haven't been able to find an adaquate answer and I feel stu-pid for having to ask.
I am trying to use the ntgraph control on an access form.
I have it registered and it works fine in Excel.
I cannot seem to access it properly in Access though. Whenever I reference it as follows:
with me.ntgraph0
.plotxy (1,1,1) <--- this is not an available method
end with
I apologize for the newbie question. It is a control that I can definitely use, I'm just missing something.
Thanks

hey guys
i have a project that uses an ms access database as a data source.
and it uses a connection string which specifies the path of the database.
now i would like to use that feature where is copies the database to the output directory
and uses the new copy as a data source (this is available as a built in option when
i create a new data source)
but i'd like to apply this feature on my current data source.
unfortunately everything i've tried causes either my data source not to work,
or renames certain things (like adds a _1 to the name and doesn't reflect on my existing queries)
or clears off all the queries on the dataset.
does anyone know of a quick and painless method ? hopefully something i overlooked?
thanks in advance

dear sir
Actually I have some problem with some TAPI function!! It is (LineGetCountry()) tapi function.
I declared LineGetCountry() function & its struct LINECOUNTRYLIST struct & LINECOUNTRYENTRY struct within a module ………….ok
The problem of mine is how to deal with LINECOUNTRYLIST & LINECOUNTRYENTRY structs within my Visual Basic code in the form to retrieve following:
A specific country code & country name.
Note: LineGetCountry() function is returning 0 so it’s successfully invoked
But *.dwCountryCode still retuning zero
I will be very graceful if you could help me by providing me with some example explain how to get country name &country telephone code, by any chance. (visual basic if possible).
thanks

Let's see your code for defining the structures, the declare for the function, and how your calling ListGetCountry(). The most common problem is that something was declared with the wrong data type, especially if your trying to convert old VB6 code to VB.NET.

I have the following code that fills a DataGrid
<small>
Dim strSQLCustomerTotals As String = "SELECT OrderID, OrderTotal, Ordered_On FROM OrderTotals WHERE CustomerID=" & intCustomerId
Dim strSQLCustomerOrders As String = "SELECT * FROM Orders WHERE CustomerID=" & intCustomerId
Dim dsCustomerTotals As New DataSet
Dim daCustomerTotals As New OleDbDataAdapter(strSQLCustomerTotals, dbConn)
Dim daCustomerOrders As New OleDbDataAdapter(strSQLCustomerOrders, dbConn)
daCustomerTotals.Fill(dsCustomerTotals, "OrderTotals")
daCustomerOrders.Fill(dsCustomerTotals, "Orders")
Dim dataRelations As New DataRelation("Orders", _
dsCustomerTotals.Tables("OrderTotals").Columns("OrderID"), _
dsCustomerTotals.Tables("Orders").Columns("OrderID"))
dsCustomerTotals.Relations.Add(dataRelations)
dgCustomerTotals.DataSource = dsCustomerTotals.Tables("OrderTotals")
</small>
The column Ordered_On in the (ms access) database is a timestamp and has the format dd/MM/yyyy HH:mm:ss.
When the DataGrid is filled it only shows dd/MM/yyyy.
How do I show the full timestamp in dd/MM/yyyy HH:mm:ss format in the DataGrid?

The date/time in any database doesn't have a format. It's stored as a serial number value. Only when the data is displayed in a table view in Access does it get formatted. You have to do the same thing in your code. If you've created your own columns, it's pretty easy, click[^].

Hi all,
which toll/add-in (like VBDOX or doxygen) do you use to comment your source code and generate the documentation for your VB2005 projects?
Thanks in advance,

You might want to take a look at the VSdocman 3.0 addin for Visual Studio. It parses your source code and generates MSDN style documentation, that is completely customisable....
There web address is: www.helixsoft.com[^]

Hello,
How can i compare the pixels in an image to the pixels of an other image? (sample code pls??)
Thanks, Zaegra

Try openning the two files in binary mode (I think) to read them byte by byte and compare. A coworker made image format converters using this method.
What is it that you want to do if the data is/not equal?
|
|
|
|
|
Well, i want if the image is not equal then i want to add it to an imagelist. As soon as it is equal, i want to write a registery setting that sais "True".

Try looking up "filestream walkthrough" in your help menu. (I use VB.Net 2003) It gives an example on how to read files.... Or GOOGLE it. "filestream" is the method you'll need to work with I think.
Hope it helps.... Happy Hunting.....
Now back to my project.....
