That was my initial thought too (and I have double checked I am parring the correct parameters) however I have another function that gives me the error message "parameter '?50' not found in collection" where there are far less than 50 parameters.

Seems rather obvious, the account you are trying run the stored proc under doesn't have the necessary rights and permissions to create databases.

Hi,
In my application i am using threads and socket programming to ping a mobile application
I want to set the timeout value for the Socket.send message
for this i have used socket.sendtimeout= value;
but the same socket is used for asynchronous communication ....so as i have set the socket.sendtimeout value its effecting the asynchronous communication..
My aim is to Set the Timeout value only for the pinging message such that communication must not get effected,,,,( I want to set the timeout period for a particular Ping 'send' only ....) If any one knows this then Please Do Let Me Know
its me sid

Hi,
FYI: you can perfcrm a ping to an IP address using the Ping Class, which exists
in .NET since 2.0; not in CF, so it would have to be the mobile that is being pinged.

I have 3 forms say, Form1, Form2 and Form3. Form1 contains a ListView control which is populated through a collection instance say Collection1. After doing an operation, I need to update the ListView present in the Form1 from Form3. Form3 is displayed from Form2.
I am looking for a best method to do this. Following are the points which I have in my mind to implement this.
1 - Make the Collection1 instance as static (Singleton) and add some events to that class. Hook event handlers from the Form1. So when new items are added to this collection in Form3, events get fired and Form1's ListView will get updated. Some kind of MVC pattern.
2 - Pass the Form1 object through the constructors to Form2 and to Form3.
Which one do you suggest ? Or is there any other efficient method to do this ?

I would suggest that you implement something like the Model View Controller pattern or the Observer pattern instead. Trust me on this - it's a much more robust design method.

So will my method 1 falls under observer, right ?
|
|

It depends on what else you are trying to do with the view - but in the case specified above, then yes - it's the observer pattern.

As I mentioned, view contains a ListView which shows the collection entries. It's not doing anything else.

Thanks. This confused me about observer and MVC. How about saying this as MVC ? Think my model as the Collection1. When it is updated, respective view's are getting updated. So is it possible to categorize this into MVC too ?

|
|
It is - both patterns work around similar areas. MVC is a more complex pattern, but it does more.

Thanks for helping me Pete.

What does this mean ? Post some code so we can try to work out what you're talking about. Also, what does 'my project have problem' mean ? Does it crash ? Does it run slow ? Does it not get invited to parties ?

How I can Make my program read or write to the USB.
|
|
|

What exactly do you want to do ? To talk to a device on USB, you need a driver for that device, then you'd code to a common interface, such as the print or TWAIN interface. To copy files, you can work out which drives are detachable, although you can't work out for sure that they are USB.

Yes I wnt to talk to a device connected to USB.
I am designing it(radio scanner) .
So the question how to make a driver.
For more specific.How to write assembly cod eto the driver using C# instructions
|
|
|
|
|
You can't write a device driver in C#, AFAIK. You need to use C or C++.

Hi
I have a custom browsable property and I want it show a column's fields from a database as it's values so the user can select them. indeed i want some thing like a property whit "enum" type but I don't want to define an enum because enums have fixed members and I want to be able to change my property's selectable values.
thanks for any help.
|
|

You want the values to show in the designer ? But that means anyone who uses your class needs to have your database installed. If you're the only one who is going to use the property, bite the bullet and maintain an enum.
