Thanks.Sorry i am just a beginner and I learn myself.The problem I face now is whenever a text file is opened,the program running is fine.But if the user choose a wrong format such as .jpg,I just wish a messagebox is pop up to indicate wrong format or file.=)

I have updated my question,is there any wrong and where should i add the Messagebox indicates the wrong format?

Thanks for reply..I mean how to let the programme know wrong format is dragged on?

Yes,it is System.Windows.Forms.Form..Thanks for the help ya.=)

Ok.I want to choose a specific file to be read.I don't know how to make the program know that which file is chosen.I mean to specify the filepath.thanks!

Hello..My problem is i open a text file and i want to pass it as an object to the class to undergo process to get the data i want in array..so i hav no idea after i choose the file,how it is to be used for the process in the class..?

I create a menu stript on the Form and I want to create a function of "save graph as.." on it.Then when I click it, a window will pop up to ask which type of file(.jpeg,.bitmap,.gif) and what filename to be saved.But the graph is a user control.how can I do it?Would you provide me some code for reference?Thanks.=)

Ok.Thanks for the information.I am trying on it,let you guys know when I know what actually the problem is.Thanks!

Thanks for reply.Ya,i use FileDialog box.But how the code should be written at directory path for the class?

eg. class: System.IO.StreamReader sr = new System.IO.StreamReader(DIRECTORY PATH)

Form: DialogResult result = this.openFileDialog1.ShowDialog();

if (result == DialogResult.OK) { string file = openFileDialog1.FileName;

}

Thanks for reply.Would you provide me some code for drawing graph line as for reference?Thanks for the help.=)

Oh..I have solved it myself.Thanks!

Is it possible to find the average for the array using Linq?

My 5!

Thanks!That's so easy with only few steps!

Oh i get it.Thanks a lot.I almost forget that.

Hi..I still can't get it..where to get that?sorry I am just a beginner..

how can i add System.Linq.dll?i just couldn't find it..hope you can solve my problem.=)

Do you mean using System.Linq? but error occur: Error 1 The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?)

Thanks everyone for replying.=) How if the array is store in string form?How can i convert them into double array and then to be used for the methods that you all have mentioned?

Thanks. I am trying on it.=)

sorry,just updated the question.=)

Hmm..I'm not really clear about it but thanks!=)
