Re: DataGridView doesn't display anything.

at least can you see the column headers? Do you use AutoGenerateColumns = true, or defined columns?

I cannot see them, the DataGridView is empty.

Where have you found the property "AutoGenerateColumns"?, I couldn't find it.

AutoGenerateColumns is not browseable in propertygrid.
You may use it from code:

dataGridView.AutoGenerateColumns = true;

Something is wrong in your code with the way you are communicating with the web server is the summary. Or something is wrong with the web server, I assumed it was your code because, well, you didn't understand the article.

Yes, first thing that really comes up should be there is something wrong with my code.
the intresting thing is it is working fine when am running the method explicitly on a button click
and when i run it as a windows service, its throwing me the 400 error.
so this is what confusing me if there is something really wrong with my code then it should break on first attempt.

Thanks,
Mamtha

Yep, let me see here. Hrm I Just finished debugging your imaginary code, it appears the error is on line 46

while (1 == 2) 
{
...

I can't guess here man, post something, if it is huge throw it in rafb.net/paste

yep here is the code part
try
{
WebClient webCl = new WebClient();
webCl.Headers.Add("Content-Type", "text/xml");
byte[] result = webCl.UploadFile("http://" + mgr.GetIniString("Server", "name", "localhost") + "/" + mgr.GetIniString("Server", "path", "localhost") + "/uploadFile.php", "POST", cachePath + "/" + TEMP_NAME);
string sresult = System.Text.Encoding.UTF8.GetString(result, 0, result.Length);
if (sresult == null)
{
log.Error("XML File could not be Read");
}
else
{
retVal = true;
}
}
catch (Exception ex)
{
log.Error(ex.Message.ToString());
}
finally {
File.Delete(cachePath + "/" + TEMP_NAME);
}

its actually throwing the 400 bad request at webcl.iploadfile method

if the problem is running as a service maybe its a security issue... of course this is just a suggestion as if i had a definative answer i would post that instead

If only MySelf.Visible was more than just a getter...

yeah even i feel that it could have to do something to do with the security issue.
but am not really sure how to handle it

OOP's - sealed class

Hi
I have one sealed Class. In this class I have created an object and set the values. Now I want to use these values in button click event. How can I achieve this.

//General Info class
public class General
    {
        private string _name;
        private int _id;

        public General()
        { }
        public General(string Name,int ID)
        {
            _name = Name;
            _id = ID;
        }

        public string GetName
        {
            get { return _name; }           
        }
        public int GetID
        {
            get { return _id; }            
        }
    }

Please note that there is no way to change sealed class.

sealed is not related to how the class is instantiated. sealed modifier just prevents the inheritance of the class.
use:

General general = new General("name",0);

could you try to describe your requirement more please.

From the code you have posted i cant see anything that would stop you accessing the properties

Thanks for all ...

Am developing application for ArcGIS dll. Bydefault the template is sealed class (no way to change) so I created one class that object created in sealed class. In the other from I have to use that information. The name and id belongs to Parcel owner name and id is Parcel unique ID. Please reply if you have any suggestions ...

How to find the position of a word

The sealed keyword means the class is not inheritable. It has nothing to do with the classes mutability. If you have a sealed class (which, btw, your code example is NOT sealed...its a normal inheritable class), just create an instance and access the values. Problem nonexistent.
