Add a custom folder in your setup project and place your MDB file in it. Set the target loaction of the folder as you need.

Thanks danish for your reply.Danish i want my database should be in my project folder and dont want to place my access db manually to the specified path.I want something like this:

Dim connectionstring As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\mycontacts.mdb;Persist Security Info=False"

Here i'm not putting the location i.e, C:\Contacts3.This'll store my records wherver mycontacts.mdb file present.I think i'm missing somthing before this ?????\mycontacts.mdb and in project->windowsproperties->setting->value i should put & or + before \mycontacts.mdb

Path.GetFullPath will give you that I guess. Is that the path you are looking for?

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.

Ah, I didn't know that. Thanks for the update; I've updated my example code to take that into account
