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.
Now I want it to upload it when you click on a button WITHOUT needing to save it. how can you upload a picture from a picturebox? I want the picture thats in the picturebox to upload. The one im having now only works if you save it first:

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.
Dim con As New OleDb.OleDbConnection 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() [Code] .....
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.
I am sending data to my server (MyServer.com) from microcontroller device using socket connection, I want to receive data using Socket and store in access database need a tracker for this work
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).

I just have a quick question, I have tried to get my code to work for a little while now and have run out of ideas, here is the codeHTML
If picturebox1.image = programname.my.resources.picturename then beep() Well the problem with that is Error3Operator '=' is not defined for types 'System.Drawing.Image' and
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
I need pick some part of the picture (or can said crop some part picture) but I want to pick it through my mouse.. so I selected that picture coordinate..
I'm new to VB. I'm trying to make some kind of traffic simulation for the school assignment. The problem I have is, that all cars show up as one moving car instead of array of cars moving separately.
I have a small picture box that I want to change its image on click, then on another click another picture, so on... There are totally 3 images. I really don't know how to do it, but I tried with the code below, but it does not work.[code]First picture shows at the beginning, lets say Image1, then on click it the image will have to change to Image2, then again on click it has to change to Image3, then on the third click onwards, only Image2 and Image3 has to swap on each click.
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 maked application which can add few picture boxes on form. But there is a problem.veryone picturebox is called pb and i can move only latest added picturebox. Here is the video about that
Dim pb As PictureBox Dim street As Integer = 0 Dim pbloc As New Point(0, 0)
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 am looking for some information on getting the colour of each pixel in a picture. The ide is to get the colour and then have my program draw a line along that colour itself. For example. If i have a black square on a white background, I want the software to be able the draw lines on the four edges of the black square, Is this possible?
i have a form with ten buttons on it. what i want to do is, when i click Button1, it will print Picture1.jpg from a file, and when i click Button2, it should print Picture2.jpg from a file. Also, i dont want the user to have to wait between the button clicking(for buffering).
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?
