Hi there,
I am currently creating a web application in c# 2005, on my search form i would like to display an animated gif image while busy doing the search in the sql database.
As soon as the user clicks the search button i want the image to become visible and then as soon as the gridview got binded with the results, i want the image to be invisible again.
Now the problem is that the image does not become visible at all
mmmm i dunno where to start finding the problem cause it does run the code but does not actually do it lol.
I am thinking i should probably use like "sleep" or threads but thats some weird stuff for me as i am still beginner. Is there any other solution to this problem?
Thanks in advance
Regards

Hello,
I think the problem is that you are running the control with the gif in the same threat (which is busy) where you are doing the search.
You could do a control.Refresh();, after you set Visible=true.
But it would only show the not- or rarely moving gif I think.
All the best,
Martin

Hi All,
I am using VS.NET 2005 and using C#.net.
I want to develop a functionality as follows.
when I run my application , it should create a Icon in system tray. When I close the application it's instance should be running in the background and Icon should be displayed in the system tray. Again when i click on my applications shortCut Icon on desktop , not the icon from system tray, it should bring forward the already running instance of my application in the background.
thnx in advance
Praveen

Hello everyone,
How can I find if two controls intersect or not ?
Best regards...
.:: Something is Wrong ::.
|
|
|
|

if (control1.Bounds.IntersectsWith(control2.Bounds))
...
That should do it.

Hi =),
I have class that works with a Generic.Dictionary and now i want to access the elements by an index.
Is there a way i can do this ? ...or are there other classes where i can access the elements by an
index and provides the same functionality like the Generic.Dictionary?
I already found the Generic.SortedList, but there my listing will be sorted and i dont need/want that =/

Hello,
If you don't need the access per key functionality at, you should use an ArrayList. (System.Collections)
All the best,
Martin

Hi Martin, thx for the quick answer, but the ArrayList is useless for me cause i need the generic-properties.
I have a Generic.Dictionary that looks like this...
Dictionary<Guid, TcpClient> tcpConnections = new Dictionary<Guid, TcpClient>();
... and in some cases i want to access an element of the listing without to know the Guid, like this...
tcpConnections.Values[2]
... but unfortunatly this dont work
|
|
|
|
|
Ok,
And if you make a second Dictonary with 1, 2, 3, ... as key and access it like this.
tcpConnection2[1]
Hope it's not complietly stupid, but I have only .NET1.1 and never worked with Dictonary class before.
All the best,
Martin

I'ts not completely stupid, all youve done is make a second index for the list. Ive accomplished many tasks in this way.
Another way is with a collection that supports both key or index lookup - there used to be one in .NET 1.1 in the System.Collections.Specialized namespace. Im sure there will be a generic version in .NET 2

Hello,
Thanks for the info.
I think System.Collections.Specialized.NameValueCollection would be the .Net1.1 non generic version.
All the best,
Martin

The class System.Collections.ObjectModel.KeyedCollection provides the functionality you are looking for. However, you have to derive your own collection class from it, as you must override the GetKeyForItem member. Maybe it is suited for your application.

I believe that the reference should look like this:
[DllImport("user32.dll")]
public static extern int GetKeyboardLayoutList(int nBuff, ref int lpList);
Then, in your code, you would work with it like this:
int[] layouts = new int[1];
int length = GetKeyboardLayoutList(0, ref layouts[0]);
layouts = new int[length];
GetKeyboardLayoutList(layouts.Length, ref layouts[0]);
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
Deja View - the feeling that you've seen this post before.

Hello Pete,
It works!!!!
Thanks a lot.
Actually I made the mistake to define it as an array.
like this:
[DllImport("user32.dll")]
public static extern int GetKeyboardLayoutList(int nBuff, ref int[] lpList);
int[] layouts = new int[1];
int length = GetKeyboardLayoutList(0, ref layouts);
layouts = new int[length];
GetKeyboardLayoutList(layouts.Length, ref layouts);
This was strange because the first call of GetKeyboardLayoutList returned the write value (Lenght of 3).
But the second call, brought back a lenght of 1 with a value 0.
But with your help everything is fine now. (And it was not the first time of corse!)
So thank you very much again.
All the best,
Martin

When you create .NET UI objects on the fly, how do you handle the events that come to them?
Lets say that in code, I create any number of new buttons and put them on my form. How do I code a handler for the click event on those buttons? I won't know their names until they exist (Button1, Button2, Button3, etc), and I can't just have a huge list of
private void Button1(), private void button()
handlers sitting around in my code.
So, how do I code a handler for Button[x]? I'm sure there is something basic I'm missing here.
Thanks,
Joe
PS. I posted a much more specific version of this question in the .NET framework forum, before I realized that I had a much more general lack of understanding here.

In continuation with my answer in the .Net Framework forum
You could create a single event
Private void Button_Click(object sender, System.EventArgs e)
For each of the buttons you can assign the event handler as
Button1.Click += new System.EventHandler(Button_Click);<br />
Button2.Click += new System.EventHandler(Button_Click);<br />
Button3.Click += new System.EventHandler(Button_Click);<br />
.<br />
.<br />
ButtonN.Click += new System.EventHandler(Button_Click);
Based on the sender you can define what needs to be executed inside the Button_Click Event

Thanks everybody, for the fast and educated responses. I think I'm on my way.
Why is it that .NET, since it implemented a
toolstripmenuitem_DropDownItemClicked event, didn't also provide a
toolstripmenuitem_DropDownItemCheckedStateChanged ? This would have made this process much easier. I realize that not every DropDownItem will support CheckedStateChanged, but even giving me a general
toolstripmenuitem_DropDownItemTheresBeenAnEvent event, and telling me which event in the args, would have been better than nothing...
Thanks again! I'll be back... now that I know where you guys are.
