m using Microsoft Visual Studio Basic 2010 and im fairly new to it. Im trying to make a small program for feedback and send it to my e-mail. I have seen e-mail sender tutorials on youtube but thats not really what I am looking for. Im looking for it to be automatically sent to me, not having to type in "To" so as if its hidden I guess. So Basically
What am i trying to do is this:I want to make a small application with 6 textboxes, the user should only can type numbers and the numbers should not be bigger than 20 so then when u click a button (btn_1) it should write the numbers to a txt file.after that i want to read all this numbers and if there are some same (repeated) numbers to display them in a label.

I want to make a small logo in the upper corner of a Form rotate.
I've seen on some forums that they have small avatars dancing and such, so I imagine it would be posible to make a tiny image rotate by it self up in the corner in a Form.
Does anyone know how to do this? Link to tutorial, codesnippets etc..
Ps. The goal is to make it smooth. Not turn 4 x 90 degrees.
I want to make a standard button quite small. maybe as small as 16x16
FlatStyle.Popup TextAlign MiddleCentre Margin and padding are all zero
The text in the button is an upper case letter X (sanserif 8pt)But even though there's enough space the text is too low and half of it is off the bottom of the button with lots of empty space above the text.
if I make the button slightly bigger. 19x19 then all the X is visible but there's just LOTS of space above and it doesn't look good.I 'could' make my own button class but surely there's an easier way. Is there something I'm missing ? maybe some combination of margin and padding that I haven't thought of ?
I will add that if FlatStyle is Standard then it isn't as bad at 19x19 but that has thick border. I'd really like to use flatstyle popup and possibly a bit smaller than 19x19
I have been trying, without success, to get rid of a �Blink� at the start of a small program.
My program opens with a title page (Form2, which is visible at 100% Opacity) that I want to fade after a few seconds, this works fine except that at the first reduction of opacity, Timer1's first 'Tick', the whole of Form2 blacks out for a moment. (Blinks)
I have a short demo program to show what I mean but don�t think I can attach it to this question. The code is shown here but I don�t know how to include Form1 and Form2. They are very simple however, they�re both Size 1000,600 Form1 has a single Button (Exit) and a Timer; Form2 has a full-size photo as background.
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]....
I developed the code on a XP machine, but I also get the same 'Blink' on my Win. 7 Pro machine.
i have a small program to get text from a DAT file. the program gets all the text and puts it into a rich text box (rtb1) then I click a button (btnformat) to split the text in the dat file into indexes so that I can output the indexes that I want to an excel file. This program works when I use small amounts of data but if I use say 800 lines of text the program crashes/ can't handle the volume of data and just stalls.

im new to these forums and was working on a small program to change the school wallpapers. i want the user to be able to choose the imageand not have to put it in a secific directory could anyone please advise me on how to do this
I are trying to write a small program for iTunes using Windows COM. We are able to talk to iTunes and create popup boxes that show the current track, and a few other small things. However, when we try to set this info to a Label for example, we get:
InvalidOperationException was unhandled by user code Cross-thread operation not valid: Control 'Label1' accessed from a thread other than the thread it was created on.
The program then hangs and locks iTunes from closing. I believe the issue is the event handler I have created, which I know very little about. We are using VB 2010, so that may change some things. We followed a rough example from a forum post HERE. If you scroll down the orange text, you will see a reply right after by Will Hughes with a "Handles iTunes.OnPlayEvent". If I add this to the end of my event handler, I get:
Handles clause requires a WithEvents variable defined in the containing type or one of its base types. Not sure if its important to the issue or not, but I found it curious. Our code is shown below.

I am working on a small personal database management program and am at the stage where I am trying to search the MS Access database given a user input.I need to look up lets say the "customer" ID and the update other records associated with that customer. Here is what I have so far.
What I'm trying to do is write a small program that copies a file from a USB to another directory so a program already installed on the computer can load this data.Usually copying files from one directory into another wouldn't be an issue.
[Code]...
If possible i would also like to change the code i have written so it just loads January2009.txt from the "root directory" of the USB rather than having to specify H: because if i put the USB in someone elses computer this could change to G: and then it wouldn't work.
I am trying to write a small program that shows a clock using a timer in vb.net, I want the clock to display the time and date as a binary display i.e. if it's 10:01:21 the clock would display boxes or buttons in rows going from 1 to 2 to 4 etc upwards and changing colour when at certain times. the example time above would be a button for 8,a for 2 to make the 10 o'clock, a button for the 1 minute and a button for the 16, 4 and 1 seconds making 21 seconds.
