Okay, I found part of my problem. First let me explain what I am trying to do.
I currently have two exe's.
1. MainApp.exe (has two forms the main form and an update form)
2. Update.exe
When MainApp.exe starts up it downloads a file from one of my web pages (version.txt)
it currently contains 2.0.0.0. I then compare my current version which is 1.0.0.0 and
if the version on the server is larger than my current version I create an instance
of my update form which says "There is an update available do you want to automatically
update?". If you click no I just close the update form and then the main form is shown.
If you click yes, I close the update form and I start the update.exe as a process.
Then I want to exit out of the MainApp.exe and let update.exe download the update
replacing the current out of date one.
My first problem is that I was doing this logic inside the MainForm constructor. If you
attempt to call this.Close() the form has even finished creating itself and thus my problem.
My next problem seems that I am in a continuous loop calling my update form in the MainApp over
and over again.

The easiest thing to do would be to load your assembly (assemblies) in a shadow cache - this is a little known feature of .NET that copies your assemblies to a temporary directory before executing them. This is done explicitly for the purpose you are asking - software updates - but also for some other, very obscure security reasons that I don't fully understand myself.
At any rate, I first learned of the approach from the Morrison Schartz plugin manager, so you might download their plugin source code and take a look. There are also several articles here on Code Project that use a strikingly similar approach, so they would be good to look at (search for "application auto-update").
For the Morrison Schwartz approach, go here: http://www.ms-inc.net/dotnet.aspx?ProductID=Plugins

Interesting, thanks I will look into your suggestions.

Sounds easy but, I am having troubles.
I can't seem to get this to work.
How do you load an exe in the shadow cache?
As in the case of .net Reflector I am trying to solve this
using a single exe.

It's all in the docs. The OpenFileDialog MSDN topic[^] contains an example that is very similar to your situation.

Hello, use the following. This open file dialog is for xml files only. Similarly use the file extensions that u use. Use *.* for all files.
OpenFileDialog ofn = new OpenFileDialog();
ofn.Filter = "XML Files (*.xml)|*.xml";
ofn.Title = "Type File";
if (ofn.ShowDialog() == DialogResult.Ok)
{
}

Hi,
I am in the process of building business objects for a database driven application. Most of the entities in the application have a single column primary key (identity value) for each object of its type. For e.g. the Report object, would contain reportId as its primary key column in the database. Most of the entities would contain common Methods like, GetItem, GetItems, Delete, Create and Update.
With the above similarity of CRUD (insert, select, update, delete) operations in my entities, I am following a Attribute based programming model to handle these CRUD operations. I have one common object "BusinessObject". All my business object inherit from this "BusinessObject". The "BusinessObject" would be able to handle all the CRUD operations - GetItem, GetItems, Delete, Create and Update, as long as the child objects inherit from the "BusinessObject" and provide some functionality and methods in them which the "BusinessObject" would need. For e.g., Report class would inherit from BusinessObject. Report class would provide a ConstructItem method that would build the items from the dataset supplied from the BusinessObject.
Protected class BusinessObject
{
Static T GetItem<t>()
{
T instance;
MethodInfo method = T.GetMethod(“ConstructItem”);
Instance = method.invoke(null, dataset) as T;
Return instance;
}
}
Public class Report:BusinessObject
{
Public Report(…)
{}
[Persistent (“paramName”, “DBType.Int32”)]
Int id;
Static Report ConstructItem(Dataset ds)
{
Report r
//Build the report object from the instance
Return r;
}
}
But, I am noticing with this pattern that the all my objects would get tightly coupled with "BusinessObject". The advantage is that there is lot lesser code and the individual objects need not worry about the mundane activities and rather focus on the business calculations. But the disadvantage is, if say a few months down the lane, if we happen to make any updates to the "BusinessObject" then the change would affect all objects which can be a very huge change and might affect all objects. This could become a testing and dev nightmare.
What do you think...
Thanks

Please don't keep posting the same question.
Also, your question doesn't make sense.
Hopefully any code you produce will be easier to understand.

Importing to where ? Do you mean having the file in resources ? Do you mean playing it in your program ? Do you mean adding it to your WMP library ?
You can import WMP as a control and use it to play files.

Hi guys
i have a custom type object named Person, in my data access layer i fill this object from data adapter and send this object to my presentation layer where there is a datagrid view to display the contents of this object, but i want to make updations based on delete, update and add new actions performed on this object from data grid view , if i am using dataset so i can do that from data adapters update method passig it the changed rows of the data set, but i am not using any data set , so what is most appropriate approach to do that ?
thanks in advance
hello

You should be calling methods on your Person class, which then call methods in your data layer to insert, update or delete your data.

Have a global integer available to all events set as 0.
In Class:
int x = 0;
In Button Click Event:
if (x == 0)<br />
{<br />
x += 1;<br />
}<br />
else<br />
{<br />
return;<br />
}

Use a flag (as member variable of your form). On Form initialization set the flag (say alreadyClicked) to false. Then in the button click event handler, first check the flag, if it is false set it to true and, finally, do whatever is needed in the handler (on the other hand, if it is true simply return).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.
