I am new to vb.net and I am relatively new to programming in general. I am creating a windows form project in vb.net which uses a webcam to take a photo of a person. The photo is subsequently saved to a database. I won't have any problem saving it to the database but I haven't a clue where to start with using a webcam with vb.net. I know this question has been asked before and I have been doing a lot of looking around the internet for a solution I can understand but I am finding this very difficult. Can someone please point me in the right direction. Any help with this problem would be greatly appreciated. Thanks in advance.
I was given the following link on 'Code Project' that solved my problem.

A more complex library than EasyWebCam that can do great things with webcams is AForge.NET. If you find yourself having a need for more advanced features, such as zoom control, I'd recommend checking it out.

I want to create a simple Visual Basic.NET solution using LUCENE.NET, indexing files in a folder.
I have searched all day, but the example code that I find is in C#.
Can someone please help?
Thanks
I wish I had a better answer for you but I suspect the best approach is to use a C# to VB.Net code conversion tool. Like you, I have never seen a VB code example for using Lucene.Net. With one of these tools, you can paste the C# code into a text box, hit the convert button and it will display the theoretically equivalent VB.Net code.
Here are a couple code converters that may be useful for you:

I have two question for labview users. I'm quite new to this language, I would like to know if design like in the picture attached (extensive use of disable diagram structure) are:
a good practice to separate part of code (I like the structure input/computation/output)
does not imply extra computation time
labview disable structure
Thanks in advance!
PS: sorry I had to hide some code not my will...(licensed)
No, the code is compiled and disable structures are ignored. But the best practise is to use subVIs (with proper connector pane and icon) to structure input/computation/output.
Everything that is connected to the left of your subVI connector pane is input.
What you have in subVI is computation.
Everything that is connected to the right of your subVI connector pane is output.
Please have a look below:

this is my first question here. I am trying to create an app for chart analysis in Objective-C.
Is there a good solution to show a stock chart in a view and at the same time be able to draw lines on this chart.
Just like in this picture shown: http://gb2007.deutsche-euroshop.de/des/annual/2007/gb//German/60/30/grafik_1_chartanalyse.gif
I am pretty new to programming and doing this exercise for a school project.
Feel free to present every solution i really need the right idea to succeed.
Seems like the "go to" solution (in other words, the one everyone runs to) is CorePlot, which you can find on GitHub at:
https://github.com/core-plot
And there's a RayWenderlich tutorial on stock charts with CorePlot, however his (or their) tutorials are more geared for iOS so you may have to do a bit of adjusting to make things work with MacOS. At least you'll be in the same neighborhood (using Objective-C, CorePlot, etc.).
I suspect any solution is going to be a bit "heavy" (or too much) for you to consider as a new programmer. Graphics & plotting within an app can be really intimidating, and you should try to get a couple other projects under your belt and in your portfolio first.

I am trying to write a program that will access a remote database and let the user edit different tables that are in the database.
My program currently connects to the database however I do not know how to select or display a particular table to the user.
Any help would be much appreciated. I do not know a lot of VB.NET so please be gentle with your answers
If you are not familiar with VB.NET then your best bet would be to go through some tutorials either online or through a book.

Finally i finished my web application and i am ready to show it to the world .. but first i need to a make a kind of demo video of the app, what tools would help me with such task ?
There will be video captures of the screen, some images off course and text ? any recommendations ?
Thanks in advance
Camtasia Studio is the gold standard for this kind of work and is very full featured, but it's a bit pricey. Somewhat more inexpensive and quite good but less full featured is My Screen Recorder Pro.
i think microsoft live meeting has a way to record meetings. What you do is to set up a live meeting with yourself( i know sounds stupid) and then you share your screen with the attendees (its you) and press record meeting. That should work.
But maybe there is something easier out there....
