It will be called the first time the class is loaded, so, basically, the answer to your question is yes.

Here's the situation:
I have 5 classes. Each class has various properties.
Example:
WindowLocation class ->
Contains properties for my main app's location, as well as other windows.
MenuOptions class ->
Contains properties for my menus. Show check margin, etc.. things like that.
No point listing them all but you get the idea.
I have them organized like this so I can simply type...
MenuOptions.ShowCheckMargin = mnuItemShowCheckMargin.Checked;
etc.
I have absolutely no idea how to save all the classes to 1 single XML file using Serialization (then read the file with serialization and set my properties up to value contained in the XML file). I looked at a million examples, and none of them apply to what I'm trying to do.
I can't put it all together, this is after days of on/off research.
I simply want all the classes to have their properties stored in 1 XML file.
Structured like this:
[Settings]
[WindowLocations]
[Main]
[X]0[/X]
[Y]0[/Y]
[/Main]
[Options]
[X]0[/X]
[Y]0[/Y]
[/Options]
[/WindowLocations]
[MenuOptions]
[ShowCheckMargin]true[/ShowCheckMargin]
[UseXPStyle]false[/UseXPStyle]
[/MenuOptions]
[/Settings]
(Note: Replace [] with HTML brackets...board screwed them up)

First of all, if you want your data to be serialize to the same file, the easiest way is to put all of your classes in the same container class (i.e. appSettingsMemory). Then it's all a matter of serializing this class to disk. You have to be aware of certain principles of serialization but a quick google search whould put enough light on your problems.
I might publish an article on this subject on my website soon so you may want to check it out at www.digitalGetto.com.
Good Luck

Thank a bunch for helping me out. Quick question though.
In my main app I'm creating an instance of the appSettingsMemory class.
appSettingsMemory settings = new appSettingsMemory();
Then, just doing this for all the properties:
settings.MenuOptions.ShowCheckMargin = ...
On exit, I'm saving settings:
settings.DumpToFile(settings);
This is working fine. It's saving all the data to the file (for each of my properties).
Problem is loading. When I load the settings, none of my program's options are getting set to what they are in the XML file.
I'm doing a settings.Load() before I run my routine that sets the program's options to their value.
this.Location = settings.WindowLocations.Main;
etc..
-- modified at 17:15 Tuesday 20th June, 2006
Edit:
Scratch that I see what's happening now. I have to set that new instance to what Load() returns. Great, it's all working perfectly now. Thx again, looking forward to your article.

I have a form with several components. After I selected options from couple of listboxes i then click on a button to perform an infinite loop. my problem is that while the application still running, i want to make a new choice of my option, and then hit the run button again. but since im application is in a loop it doesn't response spontaneously to my action on the form.
What is a good way to solve this kind of problem?

If you want your UI thread to stay responsive, then you will have to put your loop in a separate thread.

This looks like a typical case which multitherading can play a role in. Here is my take and see if it makes sense.
When you click the "run" (which I call it) button, start a thread. Place the infinite loop in the thread function. This should guarantee that the form still responds to your click while the infinite loop is looping.
In order for your infinite loop to accept new selections made by the user, there should be some data exchange between the main thread and your looping thread. This has to be done through some thread synchronization mechanisms, say, critical section or mutex.
In short, multithreading is a good way to solve your problem.
Best,
Jun

thank you. I was leaning toward multithread. but im surprised because in vb5 (which is older) we don't need to worry about this kinda problem.

What? If VB5 didn't have this 'problem', then it's because the loop was being run on a different thread behind the scenes. It's not really a problem; if you think about it logically, it's a natural outcome: one thread is flooded with work, so it cannot be bothered to do other tasks such as repainting the control or responding to user input. Therefore, long running tasks should not be run on the UI thread if you want a responsive UI.

I have datagrid with a dataset set as the DataSource. I have added a X number of tables to the dataset, but when I view my datagrid it shows all the tables in the datagrid but I can only view the first table. The other tables don't show when I click or navigate onto them.
How do I get it to open or view the other tables?
<br />
DataSet dataset = new DataSet("Sms Report");<br />
dataset.Tables.Add(sendItemsTable);<br />
<br />
packagesTables = new DataTable[sendItemsTable.Rows.Count];<br />
for(int i = 0; i < distinctPackagesTable.Rows.Count; i++)<br />
{<br />
packagesTables[0] =
}<br />
<br />
if(packagesTables.Length > 0)<br />
dataset.Tables.AddRange(packagesTables);<br />
<br />
dataset.AcceptChanges();<br />
<br />
dataGrid.DataSource = dataset;<br />
dataGridStyle1.MappingName = dataGrid.DataMember;<br />
dataGrid.Expand(0);<br />

Hello I was wondering if in C# we have something equivalent to this timer loop:
'loop for .1 second
Duration! = Timer + 0.1
Do Until Timer > Duration!
Dummy = DoEvents()
Loop

I don't know what behavior that produces in VB5, thankfully. 
I imagine something like this might do:
System.Threading.Thread.Sleep(0);
That suspends the current thread to allow waiting threads to execute
System.Threading.Thread.Sleep(100);
That specifies a "minimum" of 100 milliseconds but it could be longer I believe.
If I get flamed for answering a VB question you owe me!  Last modified: Tuesday, June 20, 2006 10:13:30 AM --

how to add dynamic control in C#.net and how to store dynamic textbox control value to the database.
|
|

Hi gurus!
How do I get values from a list view control. The view is set to details. I want to get the values from the list and dump them into variables. I have tried the "GetItemAt( x, y )" method and the "HitTest( x, y )" methods, but both give me the following error:
System.NullReferanceException: Object referance not set to an instance of an object" 
I use the following code
for(int iNum = 0; iNum < list1.Items.Count; iNum++)
{
ListViewItem selection = list1.GetItemAt(0, iNum);
string str = selection.Text;
// And then I write the values to the database
}
Any help would be GREATLY appreciated!
Kind greetings!

That error happens when something isn't initialized. Your best bet is to debug and step through the application and check the values of the list view before you call one of those. Also, potentially, you might not have initialized the list view itself.
|
|
|
|
|
GetItemAt is not throwing the exception, selection.Text is. GetItemAt expects client coordinates (i.e. where the mouse cursor is). Use list1.Items and list1.Items[x].SubItems to access the values.
