Surely this would be better done using a collection, which creates the object during the loop? Example:
ArrayList list = new ArrayList();
for (int i = 0; i < 10; i++)
{
MyClass classInstance = new MyClass();
classInstance.Id = i;
list.Add(classInstance);
}

Thanks for the response. Actually, I tried something similar to that previously, but what I'm trying to do is to create classInstance1, classInstance2, etc. I have to add these to a control and if they're not uniquely named, then the previous one will be overwritten. I hope this makes some sense - I haven't worked with C# in quite a while.

OK - the principal still stands. You are dynamically creating controls right? If so, you create the object as new object, and give it a new Name value.
MyControl ctl = new MyControl();
ctl.Name = "Name" + i;
Controls.Add(ctl);

As always, when someone tries to create variables dynamically; Why do you think that you need to do that?
Objects doesn't have names, a reference to an object may have a name. The reference doesn't identify the object, though, so there is no reason to have different names on the references in order to identify the objects.
Is there any property of the object that you need to give a unioque name? Like an ID property?

Are there any difference between event "Closing" from VS2003 and "FormClosing" from VS2005 ?
Because I just found something weird.
My Application :
private void button1_Click(object sender, EventArgs e)
{
Form2 form2 = new Form2();
form2.ShowDialog();
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
MessageBox.Show("Form1 Closing");
}
private void Form2_FormClosing(object sender, FormClosingEventArgs e)
{
MessageBox.Show("Form2 Closing");
Application.Exit();
}
If I close Form2, the difference is:
VS2003 : It shows "Form2 Closing" then Exit.
VS2005 : It shows "Form2 Closing", "Form1 Closing", "Form2 Closing" then Exit.
???

My understanding is the Application class is doing the trick here.
If you see the Application class in VS2003 (Framework 1.1) you don't get the collection of all open forms, whereas Application class in VS2005 has a property OpenForms of FormCollection type.
Therefore when Application.Exit() method is invoked in VS2003 it will fire the closing event of only that form which has called the method.
Whereas in VS2005 when Application.Exit() method is invoked, it will try to close all the open form. (That is why the message "Form2 Closing" is coming twice in your case.)
I hope I am not going wrong! If so please let me know.

I'm using visual studio 2003 v1.1. I've to read a .DAT file into dataset using oledbconnection. The contents in the files are delimited by |. While i'm using oledbconnection and adapter to fill dataset i got an error "Syntax error in FROM clause". Any one pls help me to solve this
with regards

it is impossible to answer this without the most basic of information.
1) the connection string used for the oledbconnection
2) the select query actually being used for the select command filling the dataset.
A full trace of the exception would also be useful.

Hi,
I am new to windows forms prog. I want to use a drop down list in windows form like they do in web forms. I tried combobox and set its dropdown style to drop down list but when i try to bind data to it from a database by setting its datasource as ad dataset, i am seeing only this in the combo box.
System.Data.DataViewMember.
Please help...
If you fail for the first time , call it version 1.0.
|
|
|
|

It is fine upto setting the datasource of the combo box.
But Just by setting datasource, the combo doesnot understand which field of the table to be displayed.
For that you have to set the DisplayMember property.
The displaymember property will contain all the coulmn names of the table you have retrived in the dataset.
If you want to display some property (e.g. Name) and internally use another property (e.g ID) then you can set ValueMember property as follows
DisplayMember=Name;
ValueMember=ID;
Hope this helps.

I'm very happy for you. Good work!
Maybe you can post the concept or parts of the code for others in future?
All the best,

Hi,
When i load an xml file into a datagridview, it loads a few nodes which i rather not load in the datagridview.
This is the content of the xml file:
<root>
<book>
<price>20</price>
<title>whatever</title>
<timeProduced>60958234643051454<timeProduced>
</book>
</root>
And it loads all 3 nodes (price, title and timeProduced);
And i dont want to load the timeProduced node.
This is how i load the xml file into my datagridview:
DataSet xmlDoc = new DataSet();
xmlDoc.ReadXml(path);
this.grdSmsHistory.DataSource = xmlDoc;
this.grdSmsHistory.DataMember = "book";
How can i prevent that?
Thanks in advance!

hi,
i think you can do that by integrating through the DataMember property of the dataGrid ofcourse after assigning the data source for the data grid.
you can do so in the properties panel of the DataGrid.
hope it helps
good luck

Hi,
Thats exactly how i have it although not in the property panel of the datagrid.
I've used DataMember twice, but that caused an error which closed the program.
