To add to what Christian said. If you are converting your application to C# and are taking advantage of all that OO goodness then you should be aware that in most cases (the vast majority of cases) the feeling that you need a global is an indication of a poor design.

yeah, I was holding back, but that's what I meant by 'if you must have globals'. Delegates are a good alternative, they let you tell just the other classes you need to, that something has changed.
If only C# had friend classes, things could be a lot tighter than they are.

Hi,
I want to show combinations of various factors used in the DOE experiment i.e. in first page I ask the user to choose 6 factors and 2 levels for each factor. So all combinations of these levels come down to 64. I want to show all these combinations in the datagrid in the next page.
For e.g.: Suppose A is the first factor with two levels a1 n a2 and B is the 2nd factor with levels b1 n b2, then all the combinations of the levels will be 4 i.e. a1 b1, a1 b2, a2 b1 and a2 b2. So datagrid will have 2 colums and 4 rows to display these combinations.
I have prepared a new page with a datagrid but I am not able to display all the combinations in the datagrid table.
Thanks.

The easiest way to fill a datagrid is to fill a list or an array with the values and make it the data source of the grid.

Hi,
is it possible to change the whole style of the user interfaces in an setup and deployment project using VS 2005? I mean to change the font, font-size, background-color and so on... there are no properties available or i don't find them...
Best regards

I do not believe so. You are probably going to have to go with a different installation product. The Visual Studio version is very scaled back.

hi all, i have a solution with a Class Lib. project and ASP.Net 2.0 Web Site. i want to invoke certain method at the web site from the Windows Application, and also need to invoke some method at the windows application from the website.
a search for this problem, i found that i can send from the Web Site to the Class lib. either by web service or by adding whole the class lib. project as ref. to the web site and call methods or by using delegates.
Please send examples to show exactly what should i do, thanks for any help

I don't see how you can hope to invoke stuff in the windows app from the website, the best you can do is run a webservice, and have it set flags telling the windows app to do something when *it* contacts the web service, the web service cannot contact the windows app.

delegates won't work, they only work within a process. Having a reference to the class lib will allow your web app to call methods that are in that lib, but unless they modify a common data store, this will make no difference to your windows app.

Thanks for your reply, but i've tried it using the Web Service, but what i really don't know is how to send something to the web server, my problem exactly is here i got something and i want to call certain method @ my web site application, ok using web service what is to be in this web service to forward the incoming message to the web site.
[WebMethod]
public void SendToWeb(string msg)
{
// What to do here to send to the web site
}
someone in other forum told me to do something without using a web service, by using HTTPRequest Object, as i send to my web server an HTTPRequest object as i faking something like button click or something like that, this HTTPRequest will be handled by the web server and will inkove the method of this HTTPRequest. is this right??

Hi Miguel Sarafana,
After reading Q? , i belive the best & easy way will be integrating with c# application. Matlab version 7.2(6b) comes with builder for .net , so u can write algorithms in matlab ( m file or mex) can be easily converted .net assemblies(dlls).
Details about matlab builder .net is here

Happy coding !!!!!

Hi, I have a listview with some items:
ColumnHeader columnHeader1 = new ColumnHeader();
ColumnHeader columnHeader2 = new ColumnHeader();
listView.FullRowSelect = true;
listView.Columns.AddRange(new ColumnHeader[] {
columnHeader1,
columnHeader2,
});
columnHeader1.Text = "Name";
columnHeader1.Width = 150;
columnHeader2.Text = "Note";
columnHeader2.Width = 100;
List<string> items = new List<string>();
items.Add("Some Name");
items.Add("Some Note");
List<string> items2 = new List<string>();
items2.Add("Some Name");
items2.Add("Some Note");
ListViewItem item;
item = new ListViewItem(items.ToArray());
listViewProjects.Items.Add(item);
ListViewItem item2;
item2 = new ListViewItem(items2.ToArray());
listViewProjects.Items.Add(item2);
Now I have a combobox where I want to display the note text from the selected item in the listview. How can I do this? Many thanks for any help.

SelectedItems returns selected items. SelectedIndices gets selected indexes

So I'm writing an app to help me take care of a wireless network.
There are multiple APs and multiple clients.
I want to create an app that will help me diagnose various user issues.
Right now, the problem I'm having is getting any wireless info from the user. So I want to add a little feature that will give me the following info from the wireless connection:
1. The MAC Address of the AP
2. The IP Address of the AP
3. The MAC Address of all network adapters (wired and wireless) on the client's machine
4. The IP Address of all network adapters (wired and wireless) on the client's machine
And for all the network connections, I would like to grab all the accessible data like the default gateway and DNS servers and if the address is DHCP or static, etc...
I think it should be fairly easy, no?
The problem that I have been experiencing is finding the info I need to get this done. Thus far, my searches have turned up nothing. And any help/pointers would be greatly appreciated.

I have string that i recieve and if it is over 1000 bytes i need to split it. I checked out the String.Split() but it only splits by a paticular string or char. i also tried going through a for loop and use the substring but i couldn't get it right. could someone please show me a good way of doing this?
Thanks in advance,

Hi,
I think the best way will be spliting it on the basis of count, the way u have tried in a for loop. The other and better way will be trying to take LEFT most of size say "n" count, and get it split.
so, we want to split a string of 1000 char in 10 strings of size 100 char each.
First take left 100 char, the rest 900 char you can get using "Right". If u repeat this u can split it successfully.

Did you mean over 1000 characters? In .NET, a character is 2 bytes, so you need to account for that when calculating the size.
That aside, what's wrong with
string str = "Your long string ...";
if (str.Length > 1000)
{
string firstPart = str.SubString(0, 1000);
string secondPart = str.SubString(1000, str.Length);
}

Check out String's Substring() method.

Hello My name is Guy .
I want to ask something maybe you can help me in C#.
I want to pass some Controllers & Buttons I build in Windows.Form , in to a method that can made them Enable & change there Background perhaps.
.
Any way what I Tryed all night is how to pass a Control / Button / Object to a method without ( Object Sender... , Event...) ,in to other function.
I want to take the Control object for example and send his name property trough string to a function and then to cast him into Object type or Basetype.
Something like :
this.TurnControlActive( UrlFile.Name ); // * UrlFile =// System.Windows.Forms.Control *//
and then pass in to ....
private void TurnControlActive( ....... )
{
// Here the Control / Object need to become Enabled //
}
Who to pass an Object / Control / Or how to retrieve a Control by his string name ..?
Thank a lot.
Guy D.
By the way how do I get all my controls in my form into Array ?
|
|
|
|
|
Form parent = Form1.ActiveForm;
foreach (Control c in parent.Controls)
{
c.Enabled = true;
c.BackColor = System.Drawing.Color.Blue;
c.Show();
}
I've try this eiter but it's give me only one control and I've got alot of Button and ComboBox in my Form .
Any suggestions ?

If the controls are contained in another control (e.g. a panel) then you must also iterate that control's Controls list:
foreach (Control c in parent.Controls)
{
DoControls(c);
}
void DoControls (Control c)
{
c.Enabled = true;
c.BackColor = Color.Blue;
c.Show()
if(c.Controls.Count > 0)
{
foreach( Control cc in c.Controls)
{
DoControls(cc);
}
}
}
