Hi there,
I am also facing the same problem. I am having a datatable which is bound to the listview but i am unable to remove a column from the listview. I did a work around though as follows
for (int i = 0; i < this.lstvMyView.Columns.Count; i++)
{
if (this.lstvMyView.Columns[i].Text == "description")
{
this.lstvMyView.Columns[i].Width = 0;
}
}
But this is leaving some white spaces at the end. Can anyone please help.
Thanks in advance!
Regards,
Samar

Again, the columns are just a collection so it works in exactly the same way:
for (int i = 0; i < this.lstvMyView.Columns.Count; i++)
{
if (this.lstvMyView.Columns[i].Text == "description")
{
this.lstvMyView.Columns.RemoveAt(i);
}
}

HI, I am sending mails by getting mailid's from arraylist. but after sending a mail, when i open it the to-address is appending with next id's
the code is as follows. Can any one help for this? I tried CC also. but not use.
I used ASP mail componenet
MailSender objMailSender = new MailSender();
objMailSender.Host = "mail.domain.com";
objMailSender.Username = "uname";
objMailSender.Password = "pwd";
string strQueuePath = "C:\\Program Files\\Persits Software\\AspEmail\\Queue";
string Fromaddr = txtFromAddr.Text.ToString();
for (int i = start; i <= end; i++)
{
_mailId = "";
_mailId = Convert.ToString(Mailidary[i]);
if (_mailId != "")
{
objMailSender.AddAddress(_mailId, objMailSender);
objMailSender.From = Fromaddr;
objMailSender.FromName = "Techgene.net";
objMailSender.Subject = Convert.ToString(txtSubject.Text);
objMailSender.Body = Convert.ToString(txtBody.Text);
objMailSender.IsHTML = 1;
objMailSender.SendToQueue(strQueuePath);
}
}
For TEsting i took 10 mailid's(same) in to arraylist.
After getting mail, the to address look like this.........
To: satish.g@techgene.com; satish.g@techgene.com; satish.g@techgene.com;

Looks like you are continuously adding the address to the objmailsender object. Try moving your declarations into the for loop, this will create a new object for each mail, and therefore not store the previous address.

I'd like all of my app's various dialogs to use the same icon in their upper left corner. Is there an official/good way of doing this other than manually setting the icon for each dialog one after the other? It would be nice if when this icon is changed in future versions it could be updated everywhere automatically.
Thank you!

Well, after creating an instance of your form, you could set its icon to the main apps icon, and then show the form:
ChildForm myForm = new ChildForm();<br />
myForm.Icon = this.Icon;<br />
myForm.ShowDialog();

Good ol' pie, it's been a while.

I suppose you could create a MyAppForm class that inherits from Form, and override the icon functionality, then set this as the base class for all your new forms.

If you can't spell computer, you're going to struggle in a career in IT.
The 2 words are unrelated. You can see this from the definitions.

In programming, to override is to redefine a virtual or abstract method in a derived class.
Overwrite has no meaning in programming.

override is a c# keyword, and overrides is VB.NET. I believe they do the same thing, although there may be subtle differences of which I am not aware.

Hello, I'm rather new to C#, but chose this language since I found the graphical user interface design to be rather nice to use. I'm just coming off of a Java programming GUI design course and am sick of it.
I'm building a "Battle Grid" with a few friends in a project that we expect to take a long time. We want to build an RPG playing program that'll handle what we need.
The basic run down of the grid is that it needs to be squares that will designate 1 foot of space. I want to be able to show trajectories of projectiles from the characters. Each character will take up one square. Also, I wish to be able to have the characters use cones and spheres for area of effect spells or other effects they may cause. I need to be able to click the character and have their information (not sure how I want to handle character data) display on the side too.
I'm not asking for source code, I'm looking for implementation ideas. I have a few ideas of my own, and I want to hear some feedback from the community since you guys are a wealth of knowledge I wish to consult!
1. Battle Grid.
- Manipulating a DataGrid in some creative ways to make it do what I want.
- Creating a grid of 2-d boxes for the grid, and use different drawing methods to get my aoe/cone/trajectory objects I need.
- Creating a grid of buttons that will let me do silly thing (not a feasible thought, I just chuckled when it crossed my mind)
- Creating a 3-d grid projected onto a 2-d plane.
2. Character files
- Highly organized text files, using regexs' to get all the characters data loaded into the program upon startup
- Parse MS Excel files with their data sets
- Create a new file standard (this would be an interesting project in itself)
I'm open to any advice/suggestions/criticisms that anyone would have to offer.

I couldn't get the grid control to do anything useful. I tend to use sourcegrid instead. It is completely customizable, because you have the source
