This procedure is inside of the xsd file:
Public Shared Sub AddRowData(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myDataCol As DataColumn
Dim myDataRow As DataRow
[code]....
Before it leaves the procedure I'm checking the DataSet row and I see that the Variable are there.In the next step it goes to a form on which I'm viewing the relative report.The Last form has only the Load event, nothing else. there is no any row .
First let me start off by saying that I have dealt with Winsock for MANY years and am attempting to convert my project over from vb6 to VB.Net.This program was made to handle up to 70 connections at a time and constantly sending data from Server to clients and back.
There is one packet however, that reaches up to be around 177kb when sent. The sockets are set up to sent 1kb at a time.... (No other packet actually uses the whole kb). It seems that after the server sends this large packet... the client receives the data out of order. After debugging and monitoring I find that it normally happens between 3-4kb. While the first 3 are good and in order.My question is, is there a different system I should use instead of just Sockets (I have had similar problems with TCPClient) and/or can someone maybe link me to a sample project that would not have this error?
How can i reload/refresh the same form again without losing the data stored along with the form?
View 1 RepliesI have 3 rich textboxes on my form and I need to extract the data from box 1 and box 2 and put it into box 3 without losing the formatting (as you know richtext boxes can support colour and picture formatting that i currently have in box 1 and 2). I tried the following but it strips all the formatting from box 1 and box 2.

I have a vector class...and the magnitude is single precision...Now the problem is this, when I run this with option strict on, it gives me the going from double to a single error...Why? Does multiplication imply double precision?
So with option strict on, can you not multiply single precision numbers together and assign them to another single precision variable without first convert.tosingle?

Here's an interesting issue:I've got a listview on a form that will load up properly, but as soon as I get my proxy (multithreaded) going, the listviewitems inside the listview suddenly cease to exist.
View 5 RepliesI've written a short application that consists of a form, listviewbox and a timer, the program sits in the taskbar with the form invisible, the timer is set for 40 seconds and basically it queries a database held on an SQL 2000 server, when a certain change happens within the database my form pops up and shows some data in the listview, this happens well, the problem I have is when the check is going on (every 40 seconds) the user loses focus on what ever they're working on. Is there a way I can stop this?

GetGoal just returns a string based on the value of a databound item. The reason I'm using this approach is because this is within a repeater and each row is different.

I need to start multiple processes, with minimized windows - and I don't want whatever the current process is to lose focus.Something like this should be simple enough:
[Code]...
However, whatever application is running will lose focus when this code is executed. I've looked high and low, and there doesn't seem to be any relatively simple way to do this. I had some ideas about capturing whatever application has focus (I don't want to assume my program has focus), then running the above code, and then restoring focus. However, I'm fairly certain this will require win32 API calls, and I'm not sure how to do that.
I use a DateTimePicker to pick a dateTime value and see how much time I have until it is zero: [Code] The timer is set to make changes each one second. What Can I do to have the right results?

when i do this the first msgbox pops up, i click ok, it then loses focus, i think its actually minimizing. I then have to click it in the task bar several times to get it to come back up. from then it will sometimes give each msgbox over and over just fine, sometimes it will minimizes random ones. the first one seems to be a constant.

I'm new to VB and programming in general and have not had too much trouble however i cannot figure this problem out and i've been working on it for a week. basically i have to create a program that calculates the mass of someone on another planet with the conversion numbers as constant, an input box for the user's mass, using select case format and output to a label including the name of planet ie "Your mass on &strPlantet is x" so what happens is my intWeight variable becomes zero and the lblResult is Zero. (i have not added the all the code for the label output) oh yeah i must also use a try/catch structure to prevent non numeric data from being input.[code]
