It apparently came to my mind to test my eyeBlink using an application. Through the use of my webcam, I want to perform some commands. For eg: When I blink my eye, it should open notepad. How can that be done?
View 1 RepliesI am new to working with SQL databases (and databases in general) so I do not have a lot of experience with how queries work and how I can practice them. When I was first learning xml and XPath, I found XPath Visualizer incredibly helpful after someone on stack overflow mentioned it to me.Due to this, I am wondering if a similar tool exists for SQL databases?Basically a tool that will allow me to connect to a database,enter queries and see somehow what the results would be like.
I have looked online a bit, however I have found relatively few options in terms of any utility that would do what I want, and that looks reliable.I will ultimately be writing an application to interact with an SQL 2008 server in vb.net, however for now I am just experimenting so I will know what I am doing when I actually want to create my application.So far I have managed to connect to the database using an OLE DB connection, but I am now looking for a way to experiement with queries without just querying and figuring out a way to interpret the results in my program. Basically I want to be able to remove the programming aspect of things so I can experiment with queries without needing to question anything in my code that is unrelated to the specific query.

I am looking for some advise, I currently have a VB.Net application using .NET frameworks 2 written in VS 2005. One of my clients wants to know if the application works with Unicode, at the moment I have not tested this and what I am looking for is some advise on how to do this e.g.
1) Does anything need to be added to my project e.g. code to allow this functionality. 2) Is there a way that I can easily check to see if my application can work with Unicode? 3) Advise on how other people test for this? I know it is a bit general, but as I have not done this before I am obviously trying to build my knowledge and get it right with regards to testing etc.

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

I developed the code on a XP machine, but I also get the same 'Blink' on my Win. 7 Pro machine.
i am working on an alarm system software, i am required to blink buttons whenever an alert SMS is received by my gsm modem, after checking for its authentication with the database. The buttons represents the individual units of houses that are armed with a hardware whereby whenever an alarm is triggered, the hardware sends a alert SMS which is received by my gsm modem. The unit under alert represented by the button will start blinking to show that its under alert, when clicked, it will stop blinking to show that the alert is acknowledged. But now i am facing a situation whereby when the second alert comes in, the first alert will be overwritten by it, which is not what i wanted, i want it to be like both buttons will be blinking, not overwritten. The buttons are all created when the program is running, with its text referred to the database. I have placed a timer to do all the blinking. The timer will start after the checking for authentication.

i just want to blink the label without using timer. i think its possible if i use looping structure
View 27 RepliesI'd like to create a simple application to determine the writing speed. In this application I want to view a line of text (may be more than one line) to the user to write it. And I want to select (higlight) the character the user pressed in my line and to move like a cursor to the next character (or to put underline under the current charater). How can I do that? and what is the object or component i must use to insert the text. Finally, if I want to make it multiple lines how to determine the enter key pressed by the user and how to move the cursor to the next line?

View 5 RepliesLately our network is having some speed issues at certain times of day, so what I'd like to do is make a little app that will test the network speed at certain intervals, like once an hour between certain servers etc and then write the results to a text file.

View 2 RepliesI need to create an on-screen shape (circle) that has a fill color, which will blink every X seconds (go from fill color, to white, back to fill color). This is trivial to do...BUT... i want to do it in my own class, so that I can instantiate it numerous times passing it unique coordinates for each instantiation.
How do I do it? Can a class have its own "timer control" in it independent from the form? How would I draw a shape from a class?
I've had a search through a number of extremely useful articles on the forums, however rather than reinvent the wheel I thought I would ask if anyone already had what I am looking for..A simply little VB app that opens a session to a specific IP port and then writes to a test file everything it receives. If the connection drops, simply re-stablish it and keep listening for text to write to the file.

Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.
