OK - well, like I said, when you get an item from the items collection, it's a datarow, so you need to look up the data in the column you want to view from there. That's what the control does with the displaymember property.

One error I spotted

Tazy wrote:
CheckedListBox1.DisplayMember = ds.Tables(0).TableName

should be something like

CheckedListBox1.DisplayMember = "SystemName" (or whichever column you want to display)

Hope this helps

Good Morning Bob,

And once again Thx for your assistance. I tried your response will was given only:
"System.Data.DataViewManagerListItemTypeDescriptor" when running my program. Is there anything else I could try?

This is further proof that my answer is correct. Did you try what I suggested ?

Sorry, didn't read the code fully. Blush | :O

Is it possible to connect to any webserver through socket and receive the data using Socket?

Actually, I am developing one program which sends query to Google.com through socket and reads and dumps all the search results in a text file.

The parameters I have used in my program:

Dim client As New TcpClient("google.com", 80)
Dim data As [Byte]() = System.Text.Encoding.ASCII.GetBytes("search?q=codeproject")
Dim stream As NetworkStream = client.GetStream()
stream.Write(data, 0, data.Length)
' then read response and do stuffs

But I'm getting error like:

SocketException: System.Net.Sockets.SocketException: No connection could be made
 because the target machine actively refused it
   at System.Net.Sockets.TcpClient..ctor(String hostname, Int32 port)

Any idea why I'm getting this error?

Because you cannot. Use the httprequest and httpresponse classes instead.

Thanks CG. Its working with httprequest. Smile | :)

hello all,
I'm a Asp.net developer and i know how to deploy a asp.net site with sql server database.
in asp.net website we just link with Remote server and deploy our database on that server.

but my question here is that while creating a window application in c# or vb if we have a database in sqlserver how we will deploy the sql sever database on every client machine individually.

is there any option in setup and deployment wizard. or we there is any other way.

Regards

Amit Agarwal

You wouldn't normally deploy sql server with an application, you normally have sql server running on a dedicated windows server on the network and clients connect to it, otherwise you have no single database for the company - each user has their won database, which doesn't make sense.

Bob

There's no option. People generally deploy an Access DB if they can. Otherwise you need to deploy SQL Server Express, and code to create the database within it. This is a fair bit of work.

hello guys
thanks for your reply.

but after googling i found that there are some options why which we can do this if you look at this forum reply..

http://bytes.com/forum/thread142240.html[^]

you will fnd out that Dan Guzman replied that

"Depending on your requirements, you can include the scripts in a .Net
project as either content files or as embedded resources. You can then
include that project in your Setup and Deployment project. Your custom
action can read and execute the scripts from either the resource assembly or from the file system"

this seems gud but i don't know how to achieve this.

and what about this Article:

http://www.codeguru.com/csharp/.net/net_security/encryption/article.php/c9601__1/[^]

Regards

Amit Agarwal

Basically it means you can deploy a program which creates the database. Which is what I was saying. The program still needs to run, and it need to find the DB, and run the scripts to create your tables, etc.

Access mdb files are easier.

What about SQL Express?

led mike

i have a form that allows the usere to add 0 to 4 contact numbers.

If tphone4 = "" And tphone3 = "" And tphone2 = "" And tphone1.Length > 0 Then
p.fAddPhoneNumber(contactId, phone1, tphone1)

ElseIf tphone4 = "" And tphone3 = "" And tphone2.Length > 0 And tphone1.Length > 0 Then
p.fAddPhoneNumber(contactId, phone1, tphone1)
p.fAddPhoneNumber(contactId, phone2, tphone2)

ElseIf tphone4 = "" And tphone3.Length > 0 And tphone2.Length > 0 And tphone1.Length > 0 Then
p.fAddPhoneNumber(contactId, phone1, tphone1)
p.fAddPhoneNumber(contactId, phone2, tphone2)
p.fAddPhoneNumber(contactId, phone3, tphone3)

Else
p.fAddPhoneNumber(contactId, phone1, tphone1)
p.fAddPhoneNumber(contactId, phone2, tphone2)
p.fAddPhoneNumber(contactId, phone3, tphone3)
p.fAddPhoneNumber(contactId, phone4, tphone4)
End If

above is my code. I just want to add the phone number if the text box(es) and dropdown box(es) ONLY has a data in it. also my code does not look right, any suggestions guys?

modified on Wednesday, June 25, 2008 3:11 AM

Yes, it's obviously wrong. Assuming that the user can't enter text in just tphone4, for example, you should start by checking 4, and work your way down. Otherwise you only ever store the first number. A better approach is to build a list of numbers from the four textboxes, then work out how many you have.

The other option is to check each pair individually, without the elseif. So, each one that has a pair of values, is stored, that seems the simplest solution. Why would you store phone1 b/c phone4 has a value ?

what i did was this:
If IsNothing(phone1) Then
phone1 = ""
Else
If tphone1.Trim.Length > 0 And phone1.Trim.Length > 0 Then
p.fAddPhoneNumber(klayentAydi, phone1, tphone1)
End If
End If

If IsNothing(phone2) Then
phone2 = ""
Else
If tphone2.Trim.Length > 0 And phone2.Trim.Length > 0 Then
p.fAddPhoneNumber(klayentAydi, phone2, tphone2)
End If
End If

If IsNothing(phone3) Then
phone3 = ""
Else
If tphone3.Trim.Length > 0 And phone3.Trim.Length > 0 Then
p.fAddPhoneNumber(klayentAydi, phone3, tphone3)
End If
End If

If IsNothing(phone4) Then
phone4 = ""
Else
If tphone4.Trim.Length > 0 And phone4.Trim.Length > 0 Then
p.fAddPhoneNumber(klayentAydi, phone4, tphone4)
End If
End If

basically it one by one checks the controls if there is data then adds it.

hi
I M using Arraylist to store values. i want to find the most frequently occurring, or repetitive, value in an array (ie Mode of the array).
Please help.

thanks

You need to step through the array and count the objects. You shouldn't use ArrayList if you can help it ( i.e. unless you're in the .NET dark ages of 2002 or 2003 )

I m using dot net 2005.

I can use other alternative of array list.

What is the best way to find the most frequently occurring, or repetitive, value in an array with less complexity in program.

thanks 4 reply.

OK, then you should never use ArrayList. Use the generic collections.

List<T> has a number of methods you can use. You can use findall to figure out how many of each possible element appears in the list. You can use foreach to write a method that counts items ( by storing them in a dictionary I expect ), or you can just sort the list and then step through it ( counting then becomes trivial )

Hello,

You may use the Array concept for the same as .Net provides FindAll() method for it as well.

I would suggest you to go through the given links of MSDN.

is there a way to display data into listview if the data is located in different tables in ms access? thanks

You can get the data from different location formulate in a string the way you want and then add the string...

Good luck

First, please read the post at the top of hte forum on how to ask questions. Everyone here wants help in VB.NET.

Yes, you need to write the SQL that selects the data you want to display from across the tables, by doing joins betwen the tables. If the tables are unrelated, then probably not.
