Sep 18, 2009
I want to make a littel program where there is a start buttom and a stop buttom. now when you press the start buttom the cd drive goes out and in and out and in and so on! and when you press the stop button the cd drive goes in and stays in "maby close the program to!
Now i have already made a program whre you can open and close the cd drive by pressing buttom 1 "open" and button 2 "close" but you have to keep pressing the button! can any one help me i will be realy glad!
How do i make the F1 Help Provider from buttom, with text and so on?And look at my attached picture.. the little Msgbox dosent look so nice.arent there any way that i can change the look of it?
1. Code do you code to read what this scans. 2. Does the reader just read the numbers added to the buttom of the bar code? so with that i could look an item up in a database?
I got a problem with dataview that get data from datatabel (Col1 : ID,Col2: Time) and I'm sorting by Time in desc ... when the values for example {40.21,80.21,70.25,25.2} the dataview sorting them as I need but when one of values goes above 100 for example {40.21,80.21,100.25,25.2} the dataview always sort the highest number is the buttom, I don't know why ..
This is a sample code
Dim dt As New DataTable dt.Columns.Add("ID") dt.Columns.Add("Time") [CODE]...
It might not be the best and i'm currently finishing on adding certain features, commenting it fully and possibly tutorializing it, but if ur needing an object to detect drive connections and disconnections and a lil more, here ya go. This dll is "Events 'R' Us" It also contains some simple public functions - findDrives(driveType) will find on command all of a specific drive type and return a dictionary of values - byteConverter and getMB, getGB, etc..
will convert bytes to larger metric values - getPercentage will simply get percentage of 2 figures and return as decimaland i'll give away more soon, just wanna get this out now, see if anyone has any use for it, almost every thing that can error has an error event and thus far i can only get one to fire (if usb is pushed in and pulled out really fast over and over again, i know where it fires, it's no biggie at moment)
I have a USB flash drive I want to be able to plug into another computer and automatically start the program as soon as it is plugged in and started up, is there a way to do this?
I am trying to make an application with a start button and a stop button on a stop watch program. These are the codes I am using but my seconds on the stop watch don't start.

I am writing a Windows Forms Application using Visual Studio 2008 Pro .NET version 3.5 with STRICT and EXPLICIT options both ON.
I am having trouble using ".Start()" and ".Stop()" for my stopwatch method from other methods. I have tried several different methods of writing the line that calls the start and stop, but none work, and VS keeps sending me in circles with its correction suggestions.
Form Level vb Imports System.Diagnostics Class Level
[Code]....
and promptly gives me the same error with no options for correcting it. The same thing happens for the stop command.
I created 3 timers, i want each timer to take turn start which means timer1 stop then timer2 start, once timer2 stop timer3 start. But my code seem to be running together once i click the play button.And is there any ways to easy control how my picturebox move? Because my code for controlling it movement need to keep finding the correct number for it to move.
I need to record the screen when my user clicks start, and stop recording when he clicks stop.I've searched for a while on this subject, and I have found nothing.I want to do this without adding any files to my project, I just want to use some built in function in Visual Basic, and start recording, or even take a snapshot and add it to an AVI file or something...These are some sites I have found:

This code is in VB6, but I am not sure how to even start using it?
I'm looking for a way to monitor drive activity using Visual Basic 2008. I want to create a small utility to simulate an LED in the system tray for drive read/write activity. I've found several such utilities that do this, but they all lack one thing or another, or they are over bloated with stuff I don't want or need, etc. I want to write my own so it will be like I want it. To get started, I need to know how to monitor drive activity.
I'm having a problem with some code which seems to stop my program from working correctly. Below is my (i have only added to code which i think you will only need to see.

When i select an image randomly from an imagelist on my form and insert it into a picturebox, how can i stop that image from being selected again while the program is open ?
I have a combo box I am filling on form load.I am using "SelectedindexChanged" to detect changes in the index to run the code when the combobox is used.Unfortunately, it runs the code on start up as well.
I should I do so that when a program is run, it automatically checks for conditions. If true, it will continue opening the form but if false, it opens another. What I've done is it goes directly to one form and if false it will close the form using me.hide() and loads a form using Form1.show(). Problem is, if the condition is false, both forms will open. What is the right way to do this?
I have created a program that saves and opens a custom filetype that I have created. In windows I have associated this program with that particular extension. What kind of handler do I need to tell the program what to do when it is started by double-clicking a file that it is associated with? As of right now, the program starts, but of course it doesn't know what to do with the file that started it, so it does nothing. I searched with no luck, sort of hard to choose keywords.
I'm using this code to find all the start up programs.
