Dear Danish,

Actually i just need to know what should i write before \mycontacts.mdb instead of C:\(database drive path) because if i mentioned the path then i've to put the same folder(in order to get the same path)in other system where i'll deploy my project(client).

i think i should write & before my database like &\mycontacts.mdb but still i'm not sure.

Once again Thanks

Hi all...

I want to know that how can I add different effects like - sepia,mono,negative etc. in an Image through programming. I am using VS with vb.net.

Also tell me what is the procedure to create a cartoon image from an existing image.

Thanks.

Is ImageMagick something for you? (just google it) It has huge options to do things with images programmaticly...

First question - I have some articles on image filters with C#, you can compile those to a dll and use in VB.
Second - a cartoon filter is not a simple one step process, a forum reply is not going to answer that.

Thanks for your reply.

So can you tell me that where can I download your articles on image filters so that I can use it in my project.

And also suggest me how can I create a cartoon from an image or where can I get these things.

Thanks

OK. Well, the articles are here on code project, so search the site for them. The cartoon, to be honest, I don't know off the top of my head, except that I'd expect you'd use smoothing to get a photo to look more like a drawing. Beyond that, I'd look for SIGRAPH papers or other sources with google and expect to find algorithms that I needed to turn in to code.

hello !
can u tell me what is Using keyword in VB.net ? what it do ? and if i want to write a keyword like this in C#, which keyword should i use ?

The Using keyword simply sticks a Dispose call at the end of the code. For example:

Using(sw As New StreamWriter("C:/TestFile.txt"))
    sw.WriteLine("Aloha!")
End Using

becomes

Try
    Dim sw As New StreamWriter("C:/TestFile.txt")

    sw.WriteLine("Aloha!")
Finally
    sw.Dispose()
End Try

The keyword in C# is using; it's case sensitive, unlike VB.Net

It does more for you than just call Dispose in the manner in which you describe.

It also wraps it in a Try/Finally block too so that Dispose is always called even in the event that an exception is raised. This is where its real usefulness lies. It is much easier to write the Using block that it would two write all the corresponsing Try/Finally stuff to do the same thing.

Window Thumbnail (XP)

Hi,

since Vista it is quite easy to get an thumbnail of a window but under xp it is horrible. Cry | :((

If you want to get one, you have to make a screenshot, cut the image and ...and... but if one window overlap another window you have one and a half window thumbnail (more or less).(of course, you could make a thumbnail of the foreground window, too, but i don't want to "switch" through all the windows)

Is there a better method?
(For example: Visualtooltip, viglance(not released yet) or windowfx are able to make thumbnails
But i don't know how...)

Thank you!

Of course. There's some code in this thread which may help. It returns a Bitmap given a window handle. To get a window handle (hWnd) you simply have to use the result from FindWindow, FindWindowEx or another API like that. It's C# code, but shouldn't be too hard to translate - I think that there are tools on the internet which might do some of the job for you

Do a Google (or Bing, or whatever) search for windows management information hdd serial or wmi hdd serial. It is quite complex, but there are loads of articles around describing how to use it, such as Retrieving hardware information with WMI[^].

Good Luck! Smile | :)

The person who replied to you, assumed you were a programmer and not just another guy who is looking to charge for a ton of code he copied and pasted, and does not remotely understand. Stupid of him, really....
