But why on the first time the message is displayed instantly?
The button do the same thing on first and ather times

Put a breakpoint in there and see what the connection-timeout is. I'd guess that the first time it'd be initialized to 0.

Yes , is 0 , but you think is better to initialize with another value , and how can i do this?
i'm working with entity framework.

I'm usually using the default setting; when I do remember to initialize it, it's mostly set to a timeout of five seconds, since my development-database is located on the same machine - it wouldn't need very long to respond and open a connection.
The MSDN page that I linked to shows how you can change the value.

Is it possible to run a Photoshop action with VB.NET. If so can any one tell me the way.
|
|
|
|
|
|
|
what is "Photoshop action"? are you after launching photoshop from your application? if so I would look at ProcessStartInfo
If I have it all wrong please expand your question

I just want to run a action installed in Photoshop. First my app will start Photoshop. I can do it. Then it should run given action installed in Photoshop. That is the problem

Tried SendKeys[^]?

It turns out [^] that Photoshop has an automation interface. So if you can use VBScript to automate it than it can be done with VB.Net.

True, but whether it's worth it or not depends on what he wants to do. If it's just resizing an image, using Photoshop is like using a hydrogen bomb to kill a fly.

I want to run any action given by user. Not only resize image.

How can I pass the value from pop up menu to column gridview?
In my gridview I have a link button which will open another page which has a gridview also.
After I click an item to the pop up menu gridview, the data selected should copy to
the parent page inside column gridview.
note: this gridview is a third party which is obout.
To make it clear, please see the attached image.

whenever my program used by multiple computer, i have to change the connection string to the destination computer IP (database there) and build again the project,
i wonder if visual basic support reading connection string from .txt?
can somebody gimme the illustration?
i think it's easier this way. 
|

There are many ways to get a dynamic connection string, one of them is supported directly by .NET through the application config, which has a connection string section, and even a way to encrypt that part. Start Googling! I'm pretty sure you even will find articles here on CodeProject that illustrate it all.

i found it, check this out :
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim FileName As String = Application.StartupPath + "\Config\conString.txt"
Dim TextLine As String = String.Empty
If System.IO.File.Exists(FileName) = True Then
Dim ObjectReader As New System.IO.StreamReader(FileName)
Do While ObjectReader.Peek() <> -1
TextLine = TextLine & ObjectReader.ReadLine()
Loop
Else
MessageBox.Show("Connection String not found " + vbNewLine + vbNewLine + FileName, "Failed", MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1)
End If
End Sub
working perfectly, thankyou..

you're welcome.
However:
1. That wasn't what I suggested, through the official app config file.
2. You could read all content of a text file without using streams, just a single Dim Text As String = File.ReadAllText(Path)

Have a read of this Connection Strings and Configuration Files (ADO.NET)[^]
This is what Luc was pointing you towards

did SQL Server need ADO.NET? 
|
|
|
|
|
|
|
When programming for the .NET framework, ADO.NET is the normal way to interact with an SQL Server database.

Sending SMS using .NET[^]
I used this code to send SMS by an application. it's need to pass com port as a parameter. But my PC doesn't have com ports. it only have USB ports only. So how do i find the com port which attached my phone. (Here i use a mobile phone instead of a GSM Modem)
|

One can buy USB-to-serial convertors e.g. here[^]. They tend to add a serial port to your system, hardly distinguishable from motherboard ports (very fast toggling of the control lines may be a problem, but they are fine for normal use).
They normally come with their own driver. Sometimes, the driver allows you to assign a static name to the new port, it may not even have to start with "COM". So you could have your app connect through such fixed name; or, what most programs do, have a ComboBox show all available ports (as obtained from SerialPort.GetPortNames[^])
|
|
|
|
|
|
|
I tried that SerialPort.GetPortNames function. It shows COM1 only. So if I connect my phone to a USB port can I use the port as COM1?
|
|
|
|
|
|

Plug it in and TRY IT. Chances are, you cannot use your cell phone as a modem without installing some software on the PC to enable it and that's IF you phone even comes with the software to enable it. Check with the cell phone vendor to find out.
