View 36 Repliesi`m trying to use a progress bar while i click a button to start my web cam. It needs about 2-3 seconds to display the web cam capture image in my picture box. When i use the following code the progress bar starts only when the capture image is displayed in my picture box, it waits those seconds to start. What can i do about that problem?

I want to be able to click a button on my application and the start menu appears where I've clicked. This (if possible) will replace my shell.exe. I know that with EmergeDesktop, you can show the start menu by right-clicking the desktop. How do you do that?
View 2 RepliesI want to start the time in one user only because when i add a user in my listview and click the start button both of them start their time. how can only start one user only? and when i select the other user and start their time the first one that i start is continues deducting a time.
This is my code:
Public Class Form1
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
With Timer1
.Interval = 1000 '// set interval to 1,000, which is 1 second.

Here's what I currently have:

I've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.
How can I make it so when a button is clicked it will make the program start on start-up but only if the checkbox is checked?

I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

View 4 RepliesI am looking for a method to dynamically execute blocks of code ('tasks') in a VB.Net program for a mobile robot. The bulk of the program is running in the background retrieving variables from serial ports, APIs, and the like. The user would select a task in the form of a toolbox button which pops up a dialog to enter task parameters. An accept button would add the task with the parameters to a list. The user would add more tasks to the list as necessary, and then click an 'Execute' button to start the sequence of tasks. The program would then perform the first task with the given parameters until finished, and then start the next task in the sequence and so on.
An example task would be:
GPS Navigate:
A Parameter dialog opens and a destination is entered in the form of GPS coordinates. At run-time the task compares its current GPS position with the position entered in the parameter dialog. It calculates the direction to go and drives the motors accordingly. This particular task would loop until current position = destination position. Move on to next task. The code within the tasks themselves is not the problem, just the execution of the tasks.
I am back - I have my code - it is part of another main form for a child's desktop view. I have it in a console app that works great. My new form has 3 text boxes, and a start button - txtquestions, txtUserAnswer, txtResults and cmdStart - to start the game. I made some slight changes in the numbers, because I needed it for a younger child (6-7), and removed 1 case in the case select (a square root problem too much for a little one). I click on Start button, and it freezes up. I am in Debug, but do not get any kind of problems showing me a bad line of code.
Here is my code:
Public Shared Function Parse(ByVal txtUserAnswer As String, ByVal provider As IFormatProvider) As Integer
End Function
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click
Dim endprog As String = "YES" 'define the answer for not ending the game
[CODE]......................
I am not sure about the loops, but it doesn't just freeze up anymore, as in an endless loop. Now I am getting a stop at the first 'parse'. I actually followed the instructions in a VB 2008 book to do this, and in the help section of Visual Studio with the function and the parsing. But, that is where it stops - I know I had to convert the input into - at least I think I did. The text box for input is just that input. The user's answer is typically a number, except for at the end.
I want to include a functionality in my application such that when the user clicks on a button, the user should be able to record the voice, and when stopped, the sound should be saved. Here's what I wrote for the Start and Stop button.

View 39 RepliesI have a form where the user chooses a facility and then the list of patients for that facility are displayed in a data grid view. When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?
I was just wondering if it's possible to autoclick a button without having to use the mouse hover or mouse click. I want my program to autoclick the button infinite times or as commanded by the start and stop button.
I want to click the button1 every 1 second until the stop button is clicked without using the mouse (X,Y) method if possible or which ever way is best.
I have a GUI with a few button on it and each button start an application. I want to prevent the application to start twice if the user double click on the button. How can I do that?
View 7 RepliesI submitted the same question a few minutes ago, but so far that hasn't appeared in the thread - I wonder why/ - I used the HTML to rite the code I used. When I Click the F5 / Strat Debug on menu the DOS-Based form appears and disappears immediately. I am able to run a DOS-Based program in the computer, I checked this after the Sample Console Application failed to run. The Code I used is given within the Brackets(System.Console.WriteLine("Hello World")).
View 2 RepliesWe only have few meetings for Computer subject that's why time did not permit us to discuss timer codes. Anyway, my concern (I think) is just simple (though I really do not know how to start).I plan to make a countdown timer of 60 s that will start once "Start" button is clicked and will display a message box when it reaches 0. I only know the codes for message boxes.
View 7 RepliesI am a RegEx virgin and have no idea where to start.
1. Where is the best place to start learning RegEx?
2. If i have an array list full of text, how can i search for a string which is in the list? For example, if i enter the search string "bob test" in this text: it will return a true. However, if there is only one match, it will also return a true.
3. thirdly, how can i search and pick out the link which is surrounded with the following tags?
If i can make it so if you click a button, it will start typeing something such as "Hello world!" or something?
View 5 RepliesI'm trying to familiarize myself with network programming, and what better place to start than designing an FTP client code library?So far I'm not doing very good. I'm trying to create a method which downloads a file from a remote server to a local file path. To do so, all the examples that I could find declare a byte array that serves as a data buffer. I completely understand the point of doing that, rather than reading and writing byte per byte, but I just can't get it to work. Whenever I set a buffer greater than 1 byte, the output is somehow corrupted (different checksums, media files won't play etc).[code]Because this code does work when I set the buffer size to 1, I feel like there's something going wrong with the byte order. But all of this code is synchronous, so how is that even possible.[code]

Okay I'm making a song organizer and I have a program that will load the files in a folder into a box and display the songs info into a list view. That part works fine but when you click the button to make it do anything it will get the variables that it need from the tags on the cells for each song but for some reason the one for the Album just disappears... I tried having it just show the value in a message box and it works fine. Just when I try to combine it with another variable then it wont show at all. Heres my code[code]...
