Working with multiple forms

Having a problem with get and set. The error I receive for: public void textBox1_TextChanged(object sender, EventArgs e) { GD = textBox1.Text; } public string GD { get; set; } Error: get and set must declare a body because it is not marked abstract or extern. I tried adding some code to get and set and I received this error: public void textBox1_TextChanged(object sender, EventArgs e) { //GD = textBox1.Text; } public string GD { get { return GD; } set { GD = value; } } Error:Make sure you do not have an infinite loop or infinite recursion. Any ideas?

The problem is caused by your new public property. Change the case of the field references. Change:

public string GD
{
get { return GD; } // this is calling this property and so goes round in circles
set { GD = value; } // same here
}

to:

public string GD
{
get { return gd; } // now referencing your private field, assuming that you called it 'gd'
set { gd = value; } // same here
}

Sorry, I was using automatic properties which may not be available in the version that you're working with. Follow Henry's advice and use a private member variable that the property getter and setter accesses.

Sorry, I'm not following. As you can guess I am not a very good programmer. Just starting out and I thank you for your patience. I do not have any private fields in the second form. Do I need to declare gd as private? Something like: public void textBox1_TextChanged(object sender, EventArgs e) { GD = textBox1.Text; gd = GD; } private string gd; public string GD { get { return gd; } set { gd = value; } }

Henry Minute

Almost right. Well worked out! just a small change

public void textBox1_TextChanged(object sender, EventArgs e)
{

GD = textBox1.Text;
gd = GD; // this line is not needed. When you say GD = textBox1.Text, the lines in the set part of GD
// (called the setter, guess what the get part is called) get executed; gd = value.
// The value is whatever is on the right of the = in GD = textBox1.Text

}
private string gd;
public string GD
{
get { return gd; }
set { gd = value; }
}

All right, it works!!! One more issue though. I placed a messageBox in the code on the first form and I am getting the correct string delimiter. So I know GD is storing this, however, when I go to call GetDelimiter.GD for the in the connection I get an ArgumentException was unhandled error: Format of the initialization string does not conform to specification starting at index 85. Here is the connection string: String comString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path.GetDirectoryName(FilePath) + @";Extended Properties=""text;HDR=YES;FMT=Delimited["+ GetDelimiterForm.GD +"]"; The error occures at: OleDbConnection conTXT = new OleDbConnection(comString); I know it has something to do with FMT=Delimited["+ GetDelimiterForm.GD +"]"; because if I hard code it it has no problems (FMT=Delimiter(TAB)""";). I have tried replacing "[" with "(" and that doesn't work. Any ideas on this one?

Henry Minute

When you hard code it you are using slightly different syntax Hard coded: FMT=Delimiter(TAB) Using GetDelimiterForm: FMT=Delimited[...... Delimiter and Delimited, or is that just a typo?

I apologize, it was a typo. What I meant was Hard Coded: FMT=Delimited(TAB) \\This works Using GetDelimiterForm: FMT=Delimited["+ GetDelimiterForm.GD +"]\\This throws the error

It is the double quote thing for Extended Properties that is causing the problem. In order to get a quotation mark within a literal string you have to 'escape them' This means that the double quotes in the middle have to look like \"\", for them to be recognised as quotes within a string. When this is all over look up Escape Characters for a better explanation. In the mean time take a look at ADO Connection Strings[^], for some examples. Search in the article for 'Extended Properties' and you'll see what I mean. Have a play. Good Luck! :)

Thank you Henry for all your help. I will look into this today.

Hi Henry, I have read a couple articles on escape sequences and have tried to include the same line of code(just modified to fit what I need) and I still get errors. Maybe I am looking in the wrong place but when I try and use Extended Properties=\"\"text;HDR=Yes;FMT=Delimited(" + gds + ");\"\";"; it says I need to add ";". But when I add one it tells me I need to add another. However, if I were to plug the line of code above into the code found in the Code Project page it seems fine. I think what is happening is that there is something wrong with the first part of the connection string, maybe the Source. "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path.GetDirectoryName(FilePath) + @"; Could you look at this one more time for me and point me in the right direction when you have time please? Here is the entire connection string: String comString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path.GetDirectoryName(FilePath) + @";Extended Properties=\"\"text;HDR=Yes;FMT=Delimited(" + gds + ");\"\";"; Thank you, Brenton

I have found an article that is doing what I think you are trying to do. Read text file (txt, csv, log, tab, fixed length)[^], it only uses one \" instead of two. Have a look and see if it helps.

That did it Henry. Thank you so much. Is there something I need to do is far as closing this out or giving you a rating? Let me know and I will come back.

Henry Minute

Thanks for the thanks! If you would just vote one of my posts as a 5, then people will know that your question has been answered. Good luck! :)
