Glad to be of help!
I've never used INotifyPropertyChanged. It looks like that would get me the same effect as the manual way without having to register the collection class to the collected object. Learning is fun!  Thanks!

As far as the flickering goes, i think you should just enable double buffering. Here'a an example for a data grid:
public class myDataGridClass : DataGrid
{
public myDataGridClass()
{
this.SetStyle(ControlStyles.DoubleBuffer | ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint , true);
this.UpdateStyles();
}
}
Then, instead of using a DataGrid object you would simply use a myDataGrid object that has the DoubleBuffer flag set to true.

I have a comboBox with some data from a database (the comboBox is populated from the wizard). let's say I add some more data in the database. How can I refresh the data from the comboBox? Do I have to add the new data manualy?
Thanks!

If the combobox is databound, it will automatically update from your dataset.
|
|
|
|
|
ok, then how do I refresh the dataset?
|
|
|
|
|
IF the dataset is untyped you fill it in yourself using Datarows.
If you've typed it to a database, you use DA.Fill (dataadapter.fill)

Hi,
Does anyone know of an open source .NET diagram framework that provides Visio like capabilities?
I used GoDiagram in the past, and it was very good (in a commercial product), but it is a commercial product and I need diagrammatic capabilities for a non commercial project.
Thanks

Hi Senthil,
Very impressing! (You can always count on CodeProject members  )
Thank you, I am looking at it right now.
Looks like a good candidate to start with.

Hy,
I need a little more help  . I have a DLL created in C++ which has some methods that interest me. Now I want to use this DLL in C# so I created another DLL in C# which uses the one made in C++. Only I have a few problem. Most of the methods from the C++ DLL need pointers as parameters. For example one method in C++ needs a BYTE* as parameter. I tried from C# to send a BYTE[] but it doen't help me. I also tried with REF but it still doesn't work. If I return a BYTE* from C++ and read it into a BYTE[] an error occurs "Can Not marshal return value".
A little help will be welcomed. Thanks

could you paste the C++ definition and your c# definition please.
1 line of code equals many bugs. So don't write any!!

How can i work with a Timer Control in ASP.NET?
....
....
Thanks
|
|

From what i know only ATLAS gives the ability to work with Timers. Also there always is JavaScript but that is on the client side.
Hope it helps (http://atlas.asp.net - for more details)

You could use the following:
Use System.Timers.Timer class for your timer and add a static instance of the class to your webform. (Static because you want it to run on the server on not getting initilized when a user requests something on the client). To help you a bit on that here's my code which worked for me:
<br />
public class TimerClass<br />
{<br />
System.Timers.Timer timer = new System.Timers.Timer();<br />
public TimerClass(double interval, bool enabled, params System.Timers.ElapsedEventHandler[] fto)<br />
{<br />
timer.Interval = interval;<br />
timer.Enabled = enabled;<br />
for (int i = 0; i < fto.Length; i++)<br />
{<br />
timer.Elapsed += fto[i];<br />
}<br />
timer.Start();<br />
}<br />
}<br />
<br />
public class WebForm1 : System.Web.UI.Page<br />
{<br />
protected static TimerClass MyTimer = new TimerClass(1000, true, new System.Timers.ElapsedEventHandler(MyTimer_Elapsed));
}<br />
Hope this helps.
Greetings

hi,
iam currently working on a winform application using Visual C#,i would like my application to be able to switch between two open forms and work on one without minimizing the other.
eg explore My Computer, while the window is still open explore Desktop (another window opens )
note you can switch between the two windows without minimizing one
is u can refer me to any articles or code examples that work that way please refer me
i hope you understand my question
thanks
regards paula

I may be missing something but...
Add a second form to your application, assume it is Form2. In some event on Form1 (button click whatever), put the following code
Form2 frm2 = new Form2();
frm2.Show();
Both forms should be open and available. All you have to do is make sure that neither of them is maximized. You can even limit the size with the MaximumSize property so neither of them takes the whole area.

thanks for replying
actualy that is not what im looking for
lets say i have two forms ,form2 and form2
and a in my form2 i have button and in the button click event i have the code
Form2 f = new Form2();
f.Show();
my form2 shows
i want to switch between these two forms
currently i can only work with form2 bcause its active i want both of them to be active
so if i want to change something in form1 i should be able to.

If you have created 2 forms in the same project all tou have to do is to open them with the Show method.
Form1 f = new Form1();
f.Show();
Make sure that both of the forms are visible in the System Taskbar(ShowInTaskbar Property).
If you want ony one form at a time use the ShowDialog() method

First, I'm trying to clarify your requirements. Correct me if that is not what you want. You want your application to have some virtual desktop feature so that when you switch to next window, you don't see any other windows, but you cannot minimize, hide or disable those unseen windows.
My solution is using virtual screen. Lets say your monitor has a resolution of 1280x1024. Your virtual screen will be 2560x1024.
-----------------------------------
| | |
| | |
| Monitor | Unused |
| | |
| | |
| | |
-----------------------------------
First, position all your windows in the UNUSED area. You can do so by changing the size/location property. Then, whatever window you want to switch to, just reposition that window to the MONITOR area. The key point is that whenever you open a window or draw anything in the UNUSED area, you will not see it, but your rendering logic remains functioning.
You may implement this directly to the screen, or in the memory (double buffering).
Hope this helps.
- It's easier to make than to correct a mistake.
