Program To Display The Text "Waiting For Connection..." While The Program Is Actually Waiting For A Connection?
Aug 10, 2010
I want the program to display the text "Waiting for connection..." while the program is actually waiting for a connection. However, when I run the program, the form doesn't even appear because the TCPListener is waiting. What can I do to have the program appear and show the text while it's waiting for a connection?
Imports System.Net.Sockets
Imports System.IO
Public Class frmMain
Dim client As TcpClient

I'm writing a program and have run into a bit of a snag. I have the code perform a button click on certain buttons, the reason for this is I have a bunch of buttons that each do something and one that does everything automatically. I suppose I could rewrite everything under that one button but that would essentially double the size of my program, I could use an if statement to catch the fact that the program is in automatic mode but that would be about 15 conditions (not looking forward to writing that statement ;p)
Clicking the buttons is a nice simple, clean solution. The exception being the program performs the click then continues on executing the rest of the code in the actually clicked button while at the same time executing the code called by the code click. Main problem with this is the data that needs to be populated by the code click isn't being populated fast enough for the code in the main button so then there is errors, blank data, program doing nothing. A simple sw timer to delay could work (I know how to make one of those) but the problem with that is the program is executing against a webpage and if the webpage takes a few seconds longer to load then anticipated everything is out of wack again. I'm looking for a simplish way to cause the program to wait for ALL code called by any raised event to finish before proceeding.
i.e. Call Button.clickEvent > Wait for code and subroutines executed by Button.clickEvent to finish > continue with rest of code in button.
Below is the code I'm using so far for the user clicked button.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Button4.PerformClick()
'Need to wait for all code executed by Button4 and anything it calls to finish
x = 0

I would like to execute an external program within powerpoint after the presentation has loaded so i can see if its working. In short my overall objective is to execute the external program which will open up the command prompt and use the sendkeys method to sendkeys to command prompt which help it to run a script at the correct time (which is after presentation is loaded).

I have a form in VS2010, written in VB, and it has a subroutine calling for information out on the web using an httpwebrequest object. It takes a while for the response, and I would like the subroutine to write a message to the form (into a Label) for the user to see while waiting for the application to respond.
I tried writing the message with a Backgroundworker and then as a second thread. I got it to write the message, but it always seems to wait for the http response before writing the text. How do I write the text immediately, while waiting for the data?

In my program I got multiple spots where I open a Connection to an Oracle database, read some lines via a stored procedure which returns me a cursor, put them in an IDataReader, close the connection and go on.
Now everything works fine till the point of closing the connection. I've watched the connections opened to the database via TOAD for Oracle and I figured out, that the database seems to keep an connection opened after I said m_Connection.Close and m_Connection.Dispose.
I use Oracle.DataAccess and get an error after a short time, that there are to many connections. I debuged my session and made sure, that vb performs the close() command and it does it, but the database not.

I have an application with a number of forms that basically access the same data (or subsets of it)Can the data adapter, connection object etc be opened in a module so that all the forms have access to them to avoid writing the same code in each form?I had a go at doing this but they seemed not visible to the form?

I have a dataset that I created through the wizard, to pull the data and their types from the database tables and prevent some of the headaches of creating the tables and data types individually.I am looking for where the database connection for the dataset is defined at so I can change this. The reason being is I have added a database connection dialog where the user will select the location of the database server and I am wanting to pass the connection string from what the user selects to the dataset so the dataset uses this as its connection string instead of the default one I defined in the wizard.Where is this defined at so I can change it?

I'm looking to write a custom program in VB.NET / C++ / C# that would allow me to monitor a system's vitals over a Remote Desktop Connection. I'm only looking for tips on how to implement a connection like this in code (eg. is it just a simple object or call to a WScript function? or is it much more sophisticated?). As to the specifics of operation after making the connection, I have that figured out based on another program which shares some similar features. This doesn't have to go through an RDP connection, I'm definitely looking for better ways. Reason I mention RDP is because I currently do this manually over an RDP connection, but I don't wanna have to constantly open the window.

I am writting an application and I used Wizard to create DataSets which auto-created their own xml code. This code uses the saved in My.Settings Connection String. Being a setting with an unchangable 'Application' scope i cannot change its value at runtime.
The problem is that when I install the Application to my customer the Connection String will have to change (maybe more than once). So is there a way to change the Connection String used by these objects at runtime ?

I have written a simple VB.NET program that connects to a MS Access Database. This program runs in Windows 7 XP Mode, but does not run properly in straight Windows 7. Somehow, the Windows 7 does not connect properly or read the MS Access database data properly with the DataAdapter.Fill method. I have dual monitors, so I can run the identical program side by side (one in Windows 7 and the other in XP Mode) - one works and the other doesn't (it doesn't crash, it just get "nothing" from the database when accessing - acts like it's not connected). Has anyone else run into this, or similar, problem with VB.NET and MS Access connectivity?

How to make a chat program. Well I just copied code in and the program worked. I can send a message to the server and it sends it back just fine. But I can only send a message once.

I am practically a beginner at Visual Basic, and programming in general. I have created a simple falling bricks game in Visual Studio 2010. Every 100 milliseconds, it scrolls down bricks and if the player's position hits a brick, the player loses. I am having trouble with input.
I do not know how to make the computer accept left/right arrow keys as input, without having to wait for an input every 100 milliseconds. Here is the code:
Imports System.Threading

I have a problem with an App I am writing that lists information about various media on your computer and lets you launch it right from the app. My problem is, when launching an intensive process, like a game for instance, it is desirable to shut down the app to not hog precious resources. Here is the code i have so far...
[Code]...
This code works fine, but for one small detail. The app exits before the desired process starts, thus cancelling out the process all together. My question is, how do I get the app to wait for the process to start before exiting?
