What exactly is happening?

Thanks for reply,
The event handler of a button is responsible for executing the following code,
weBrowser1.Stop();
But When I click the button, I see that the webBrowser is still trying to load the navigating web page and stops when it fisnihed loading, and sometimes it takes long time to load a huge page. I also verified that the event handler is really working, so there is no chance that, I clicked the Button to Stop WebBrowser but weBrowser1.Stop(); is not being executed. I am wondering, why the WebBrowser is not Simply being Stopped !!!

So, as an example, you have code similar to:
private void stopButton_Click(object sender, EventArgs e)
{
webBrowser1.Stop();
}
Correct?
Have you placed a breakpoint on the stop line to see if it's actually being called?
|

|
|
|
YEs, Right, My code is exactly like that and I placed breakpoint and also placed MessageBox.Show("I am inside the event handler") code to confirm that the event handler is really being called.

Guys,
I'm trying to write some classes so I can handle XML files more easily. I'm having quite some difficulty with the terminology of the Framework.
Are there some good tutorials out there that are clear? (I quickly searched CP, but couldn't find anything right away).
My goal is to be able to load/save (this one's OK) and modify/read the XML. I'm having difficulty with the terminology element/node/attribute.
I was thinking that an element and a node was the same and they have attributes, but after playing with it, that doesn't seem to be the case?
Any links/tutorials?
many thanks!

The following link will show you the best XML tutorial I have ever found in the internet. This Tutorial will not will teach u XML, but also teach u how to work with XML in C#.NET.
good luck.

thanks a lot, the first thing showing up in google was a java snippet although the title on top of the page said C#

Elements and attributes are all XML nodes. A XML node is the basic building block of a XML document and besides the both named at the beginning there are some other types of XML nodes e.g. the XML declaration. To see what types are distinguished by the .NET Framework take a look at the XmlNodeType enumeration.

i am deleting a record from the database and i get an exception message : datatype mismatch, i have the following query for deleting a reocrd from the database:
string query = "delete from registration where id = '"+
Convert.ToInt16(this.id.Text)+"'";
its point to the line 568
which contains:
com.ExcecuteNonQuery();
|
|
|
|
|
What is the type of your id column.
According to your query it must be tinyint.
do Convert.ToInt32, if it is of type int
Sincerely,
Elina
Life is great!!!
Enjoy every moment of it!

if it's an int type you shouldn't use the single quote characters
what db are you using
sql server normally likes
delete <tablename> where id = 7
access tends to like
Delete * from <tablename> where id = 7
i would guess it's a type conversion thing though, by putting the ' char in you make the data provider pass it as a string type

remove the single quotes and it will work.

G'day folks,
At the moment I am writing a little application which utilities multi threading to do some processing. Essentially, my application creates a fixed number of threads,i.e. 5. Each thread when started performs three main tasks which represents the operational states the thread is in. The operational state is essentially a particular method that is executed to perform the specific task.
In my current design I have created a global array which contains five elements to hold each thread's operational state. Each time the thread moves to a new operational state, the thread's operation state value is changed in the array. I have used the correct locking processes on the array when a thread has to update it. Here is some code which shows I how the thread is started:
int []operationalStateArray = new int[5];
void Main(string[] args)
{
Thread[] ThreadArray = new Thread[5];
MyClass myclass = new MyClass();
myclass.FetchStatusArray(ref operationalStateArray);
operationalStateArray [0] = 1; //1 implies encoding task
ThreadArray[0] = new Thread(new ThreadStart(myclass.ProcessData));
ThreadArray[0].Start();
ThreadArray[0].Join();
}
Having explained my application, my question is that: Is the approach I have taken in accessing the global array using threads is okay or are there better solutions? Is it okay to pass operationalStateArray as a reference to be manipulated by the ProcessData method in MyClass?
If anyone can give me their feedback on this I would most appreciate it.
cheers

Hi
I think that you can have a class (for example Operation) that has a state property ( a readonly property) that gets the state of the operation.
Operation class has a ProcessData method that will be used in ThreadStart to start a thread and within this method the operation can change its state.
Using this approach , you can have unlimited operations (not only 5 or a known number of operations) and no one can change the state of a opration except an operation itself that means you don't have to be worry about locking you objects and finally there's no need to remember the index of an external array(when an operation wants to change its state)
Good Luck

thanks for your feedback. I took your solution on board and managed to derive a solution based on event based asynchronous design pattern. I just had to look a bit harder in the local help of VS2005.

Hi,
I was wondering how i could print the content of an array string into a messagebox without using a for statement.
Thanks in advance!
|
|
|
|

Use the string.Join method to concatenate the items in the array into a single string.

Hi,
I am creating a designer for a control and would really like to access the Select Resource Dialog to choose an image, however I can not seem to find it anywhere.
The select resource dialog is the one which is shown after clicking the ellipses on the property grid for the Image property for a Button.
Anyone know what this dialog is called?
Thankyou

Many of the editors are implemented based on the type of the property.
Have you tried just implementing a property as such:
...
private Image myControlImage;
[Browsable(true), Category("Design"), Description("Sets an image to display in the Bubbah Control")]
public Image Image
{
get{return myControlImage;}
set{myControlImage=value;}
}
