    Do I even have to use Serialize and Deserialize to read and write to and from files?
  2. aewarnick
    I did notice in the book that NewLog is just an object class. Not a form and it says [serializable] at the top. Do I have to do some major modification by putting all my code in another place?
  3. aewarnick
    I cannot convert my stream to a type NewLog just like my book says. private void ReadIt() { string f="CommLog\\2_9_2003.txt"; stream=new FileStream(f, FileMode.Open, FileAccess.Read); NewLog Log=(NewLog)reader.Deserialize(stream); } I always get the error message about not being able to convert it.

    private void SaveB_Click(object sender, System.EventArgs e) { string FormData=GetData(); string f="CommLog\\"+DateTime.Now.ToShortDateString()+".txt"; f=f.Replace("/","_"); MessageBox.Show(FormData); output=new FileStream(f, FileMode.OpenOrCreate, FileAccess.ReadWrite); writeIt.Serialize(output, FormData); } Why do I get a whole bunch of silly characters in my text file when I save it to disk?

    Nevermind! int[][]x = new int[6][]; should be: int[][]x = new int[3][];
  6. aewarnick
    Error: Highlights the j loop and says, "Object reference not set to an instance of an object." Help. int[][]x = new int[6][]; x[0]=new int[] {1,2}; x[1]=new int[] {3,4,5}; x[2]=new int[] {6,7}; for (int i=0; i<x.Length; ++i) for (int j=0; j<x.Length; ++j) { RTB1.Text+=" "+x.Length; TB2.Text+=" "+x.Length; TB1.Text+=x[j]; RTB2.Text+=x[j]; }

    I'm with you. I don't feel like figuring it out either. It works now, so I am happy. Actually I have a subscripted array problem now that should be simple but is giving me trouble. I'll post that elsewhere.
  8. aewarnick
    I tried and tried till I could try no more!! So I just changed it completely: //do3 public void do3() { TB1.Focus(); TB1.SelectAll(); check2(TB1.Text); RTB2.Text=y; } bool b=false; string y=""; void check2(string text) { char[] chrarray = text.ToCharArray(); foreach (char x in chrarray) { if (char.IsDigit(x)) y+=x; else if (x=='.' && b==false) {b=true; y+=x;} } }
  9. aewarnick
    Why do dots always print when the bool value should be set to true after one dot? private void do3() { if(TorF(TB1.Text)) RTB2.Text=TB1.Text; } bool check2=false; public bool TorF(string str) { char[] chr = str.ToCharArray(); foreach (char dummy in chr) { if (char.IsDigit(dummy)) return true; else if (dummy=='.'&& check2==false) {check2=true; return true;} } return false; }
  10. aewarnick
    That is it!!
  11. aewarnick
    Works great! But there probably is anotherway to do it.
  12. aewarnick
    Ok. That clears things up alot. Thanks so much for all your help. I am learning things.
  13. aewarnick
    I tried removing that and also just writing Run(); but it never works without Application.Run(); Is that the way it should be? Also, I noticed in the properties window something about having more than one Main(). Is that possible?
  14. aewarnick
    Let's just make it simple and say that the picture_Click will be disabled after they use it once.
  15. aewarnick
    I found it and changed the starting object to form1 (it was my only choice.) but it still does the same thing when I remove Run.
  16. aewarnick
    I'll try it out later. I am gathering all this info so that I don't forget it. Thank you.
  17. aewarnick
    You mean this picture (attatched)
  18. aewarnick
    Well, I would like to be able to set a limit on how many times the user can press that button at certain times.
  19. aewarnick
    I went to Set startup projects and they are both under WindowsApplication2 namespace.
  20. aewarnick
    Anytime
  21. aewarnick
    Also, this does not compile: pictureBox1.Lock=true;
  22. aewarnick
    How would I make this click event only do these commands once and another set every other time it is clicked? Use a while or for structure with a static variable? private void pictureBox1_Click(object sender, System.EventArgs e) { string outputStr = ""; foreach(char myChar in x.Text) {//even gets spaces: if(!Char.IsSymbol(myChar)&&(!Char.IsLetter(myChar))) { outputStr += myChar.ToString(); } }
  23. aewarnick
    I tried removing Application.Run here but the program immediately closed. static void Main() { Form3 frm3=new Form3(); frm3.Show(); Application.Run(); }
  24. aewarnick
    I have a picturebox that is clickable on my form. I would like to disable the click at a certain time but when I use pictureBox1.Enabled=false; to disable it the gif animation stops. How can I disable the click without stopping the animation?
  25. aewarnick
    What if I come accross a situation where I can only test to see if a user enters in characters or numbers but I cannot test by using try/catch. if (textbox1==(char)){}??? if (textbox1==(int)){}??? if (textbox1==(double)){}???
