I wanted to open a URL from my VB.net Application on a button click event (for sending SMS from my application). However, I don't want my users to know about it & I don't want to have a browser pop up and execute the URL.
Is it possible to do it invisibly? And once it is done, is it possible to close the invisible browser window too?

View 7 RepliesIn a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another

View 4 RepliesI caused the VB.NET2008 IDE to do something extremely odd and unintentional with some code I was writing. As some of you know, I mostly write programs for industrial equipment. On one of our products, I needed to make certain forms automatically close after a timeout period. To do this, I began programming a usercontrol with a Timer on it (interval = 1000) and a ProgressBar. Timer.Enabled was set to the Enabled event so I could toggle it. When the control counted to it's timeout period, it would call Me.ParentForm.Close
So I build my project, and drop it on a form in the IDE and I see it begins counting! Huh... I had no idea timers were active in the IDE. I wonder what happens when it hit's it's trigger? I figure probably nothing since Me.ParentForm was actually the designer. When it triggered, the whole IDE crashes without save. I tried it twice now. Here's my

I may be deploying my app (its a database software for videos) to 4 - 5 computers. I want to add some new features but have the software update automatically and silently. Due to security holes or issues with bugs, I don't want to give the clients the choice to update. I just want it to check for an update and if one is available, it can SAY that its updating on a label but that's about it and it automatically updates without confusing the user or wasting any more time than it should.

View 5 RepliesI have started to use VB .net (Visual Studio 2008). I made a small program which starts with form1. This form1 automatically loads form2 and the form1 should close. But when it closes form2 closes as well.

Handles MyBase.Load
Me.Show()
Form2.Show()
Me.Close()

I started making a program, and I wanted to insert music to play. i just added music to the resources and used the code my.computer.audio.play(my.resources.name_of_the_file and so on. this worked perfectly until I added the 5th song. the resource file became to large and vb said it was corrupt. so I thought of a new way: making a music file opener. I made a code so a window opens where you can select your .wav files. that all worked, but I couldn't get it so the music would start automaticly or that it would actually play. this is the code I have so far:
vb.net
Dim Open As New OpenFileDialog()
Open.Filter = "Wav [*.wav*]|*.wav"
Open.CheckFileExists = True
[Code]....
as you can see I put stars in the place where I have no idea what I have to do next. I e.g. tried my.computer and a path
make a quick app that will create 3 random letters, and search google with it which i can do. It is then ment to open the first link, and grab a sentence, or a group of words randomly.

View 5 RepliesI'm developing a WinForms app in VB.NET, that handles sets of style data, and when the user clicks on another set's label, it prompts through a dialog "You are leaving this style preset to edit another one. keep changes on this one? [Yes] [No]".But, I'm facing the problem that, when the user clicks either option, and the dialog closes, everything has to be refreshed, and loading the form again seems a good option.[code]But as soon as that sub is called from the prompt, it crashes the application. (doesn't show an error in debug, simply crashes) How should I, from a given dialog, close the dialog, it's parent, and re-open it's parent? (which triggers all the Dialog_Load() code of the parent)

SQL connections confuse me sometimes In almost every SQL related code on the internet the routine is like this;
* Open connection
* Execute SQL command
* Close connection
Is it good practice to just open a connection when the application starts and use that connection until the application closes?I know that sequential connections are required when processing more queries, but what if I need to poll a certain Table every x seconds? Isn't is better to keep that single connection open for as long as the application is running (and re-open when a failure occurs) instead of opening a new connection every x seconds?
