ArrayList al = new ArrayList();
Label mylabel =new Label();
al.Add(mylabel);
al.Add(mylabel);
// now I have two objects in the array...
((Label)al[0]).Location = new Point(100,100);
((Label)al[1]).Location = new Point(100,200);
// that's it
when the program run i see only one label.
why?

Hi,
The problem is that you're are adding two times the same isntance of label...
Try to create a new label when you're adding it to the arraylist. Try this:
ArrayList al = new ArrayList();<br />
for( int i = 0; i< 10; i++)<br />
al.Add(new Label());<br />
((Label)al[0]).Location = new Point(100,100);<br />
((Label)al[1]).Location = new Point(100,200);<br />
...<br />
((Label)al[9]).Location = new Point(100,200);
Too, You can create an array of labels instead of an arraylist...

did that
still
i don't see my labels on the form
maybe I need to use:
controls.add ?

Yes. You're right. The code is the following above:
ArrayList al = new ArrayList();<br />
for( int i = 0; i< 10; i++)<br />
{<br />
Label oLabel = new Label();<br />
al.Add(new Label());<br />
this.Controls.Add(oLabel);<br />
}<br />
((Label)al[0]).Location = new Point(100,100);<br />
((Label)al[1]).Location = new Point(100,200);<br />
...<br />
((Label)al[9]).Location = new Point(100,200);

From PC1 I am trying to connect to a webservice on my machine.
This path works fine on my machine.
http://gbws-00201234/codeservice/inger.asmx
It lets me see all the functions.
But when browsing from any other machine on the network, it gives an error:
The page can not be displayed. page is unavailable...
On my machine I have got firewall turned off.
Other pcs can ping my machine and vice versa.
Any ideas please?
Thanks

Hi,
Developing Env: .NET Studio in C#, windows XP
target: a COM object used for excel user (RTD)
I have no problem to compile and run the project in my
machine. The excel is working great with RTD calls.
However, I got issues when I try to deploy it to another machine.
I use
regasm my.dll /tlb (or) regasm /codebase my.dll
gacutil -if my.dll or gacutil /i my.dll
The excel is not working with RTD calls.It's not invoking my dll (I had log file in my dll ).
I am not sure why it's not working in other machine by registering the above method.
Is there any way to register .NET dll and I can
can deploy it in other machine and let Excel users call it
directly (by RTD)?
Thanks,
Gnanaprakash

Hi,
Here you have sample code to open a file using OpenFileDialog:
private System.Windows.Forms.OpenFileDialog openFileDialog;<br />
string sPath = "";<br />
DialogResult dr = openFileDialog.ShowDialog(this);<br />
<br />
if (dr == DialogResult.OK)<br />
{<br />
sPath = openFileDialog.FileName;<br />
}

When you say download are you saying you want to pull a file from a remote web server (http)? Or from a remote network share? Cause each one uses a different method to retrive the file. Or is the file local on the users system?

There are several articles here that provide a file downloader control.
Search[^]
Each one is a little bit different and provide for different features, but they all boil down to the same concept. Of course, I'm being a bit biased and will tell you to look at the article I wrote on it first.

I have created my own custom progressbar controls and i wish to assign them an icon for the toolbox.
I have read everything i found on the net including the super http://www.bobpowell.net/toolboxbitmap.htm[^]
The orginal idea was to assign as an icon the icon of System.Windows.Forms.ProgressBar but i have tried everything and I couldn't do it.
So i decided to add a new icon. That also didn't work. Finally i decided to use the ToolBoxBitmap("FILEONDISK") constructor but that didn't work also.
So two things are happening.
1)It doesn't work which is not probable
2)Something in testing is wrong.
My test procedure has been. Cleaning the project, building in debug and then in a designer of a form looking the toolbox.
Please if i'm doing something wrong tell me.
Also If someone has the solution to pute the .net controls icon in mine please also tell me.
Because it matters here are some details for the project
Default namespace: MyComponents.Windows
Assembly Name: MyComponents.Windows
The control is located in Controls\ProgressBar.cs in the project dir MyComponents\Windows.
Here is the class declaration
{<br />
[ToolboxBitmap(typeof(ResourceFinder), "System.Windows.Forms.ProgressBar.bmp")]<br />
public class ProgressBar:System.Windows.Forms.Control
ResourceFinder is an internal class outside Namespace declaration. As i have understood this should be sufficcient.

You need also the [ToolboxItem(true)] attribute.
In my tests for this I went crazy because it **seems** to work only if you reference the compiled dll and not with a reference to the project and this is not documented at all.
|
|
|
|
|
This is what I'm using and still it doesn't work.
<br />
internal class ResourceFinder<br />
{<br />
<br />
}<br />
namespace MyComponents.Windows.Controls<br />
{<br />
[ToolboxItem(true), ToolboxBitmap(typeof(ResourceFinder), "System.Windows.Forms.ProgressBar.bmp")]<br />
public class ProgressBar:System.Windows.Forms.Control<br />
In the same solution there is the GUI in another project. O compile the control and VS2005 populates automatically the Toolbar. But the icon is wrong.
