VS 2010 - Send A Picture Via A TCP/IP Connection ?
Feb 8, 2012
I have come to the conclusion that it isn't a simple 2 line code, to send a picture via a TCP/IP connection. It has to be converted to bytes, sent and received properly on the other side. In short, I've tried this, and (as you can imagine, now that I've made this thread) I failed. Here's my
Client Private Sub ConnectBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ConnectBtn.Click
If IPTxtbox.Text = "" Then
[CODE]...........
In short, I've made it possible to send strings, but... Sending Bytes and receiving them properly, I can't seem to manage.

When it comes to database connections what is the difference between closing a connection & disposing a connection? I'm hoping to gain a more technical understanding of what happens when each is called & the effect on the database.

Try
con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = D:\project\login.mdb"
con.Open()
str = "insert into table1 values(" & Text1.text & ",'" & Text2.text & "')"
cmd = New OleDbCommand(str, con)
cmd.ExecuteNonQuery()

If I insert integer value it will be updated in database every thing is ok but when I want to write some string in my textboxes and want to send them I get connection error.

How can I send and recieve serialized objects over a TCP connection with size and data type values in the header (within array(0) and array(1) values)?I know how to serialize and send the object using BinaryFormatter.Serialize.I dont know how to take the recieved data and put it into an array of bytes().Also - on the receiving end I dont know the size of the object sent therefore I dont know when to stop reading the data stream so I cant use: Dim Obj As ClassName = DirectCast(BinaryFormatter.Deserialize(Stream), ClassName).

To make this simple i have a multiple forms. On form 1 is a picturebox whose image property is set through a series of case statements as follows:
If (MyImage IsNot Nothing) Then
MyImage.Dispose()
End If
Select Case cnt_ACerv
[Code]...
The issue is that whenever i navigate away from this form and then back to it the picturebox is glitched and will only appear as a white box with a red X through it. Im sure there is something simple i am missing or a refresh that needs to be done but at this point i am unaware of what to look for. I have checked the variables inside my case statements before i navigate away and after i navigate back and they appear to be correct at both points.

In the project I am translating from vb6 to vb.net, one of the key features is in drawing various graphics like lines, circles, arcs, rectangles, etc in a Picture Box control. From what I have run into, there seems to be at least two different approaches, using WPF and GDI.

I am successfully able to pull images into a picturebox in my program and manipulate them in a variety of ways. What i need to be able to do is the following.
1) Pull images into a picture box on my main form and dynamically resize either the picture box or the image so that the image doesnt lose its scale when it comes in
2) Have a method of pre-screening an image to be loaded before it comes in so that i can change its size without losing scale .. ex.
if my image is 1200x1200 i do not have that much room on my form so i would want to say something like
if getimagewidth()>600 then
me.picturebox.width = getimagewidth()/2
end if

I have two picture boxes and a timer In the timer, I have this
[Code]...
I have already got the code so I know when the picture has been changed so I don't need to do anything with that (I am pretty sure) but the big problem is that when PictureBox1 already has an Image, the next Image in the clipboard that is copied replaces PictureBox1's Image instead of going to PictureBox2. Will anyone be able to solve this?

I'm making an picture manager for personal use, and was wondering if it's possible to list up more information of an image. For instance, In Windows 7 there is a feature when I left click one time at a picture I get a little thumbnail and some information about the picture, like: Dimensions, ISO-Speed, Camera producer, blitz mode etc.
So my question is; How can this be implemented to Visual Basic 2010?

I have a picture box that is wider than the screen, with a stretched image. Can I put scroll bars on this picture box? I tried making the form as large as the picture box (which is 3840 x 2160) and then just move the form sideways by clicking and dragging on the control box, but the form will not go larger than 1940 x 1100. Can I put scroll bars on this picture box, or is there another technique I should use?
