Now I understand I can use
System.Diagnostics.Process.Start("http://some.url.com");
to launch the default browser and navigate to a specific page, and I also understand that I can launch a specific browser, which will then go to the default home page using
System.Diagnostics.Process.Start("iexplore");
However, is there a means of launching the default browser to the default homepage? (without checking the registry to see what the default browser is preferably)
Perhaps there's some special url I can navigate to (like about:blank, but representing the default homepage)
I have no blog...

Erhm, the default browser setting is stored in the registry, su you'll need to check the registry in order to find the default browser.
Why don't you want to check the registry?

True. He solicited a number near 'Rate this message'. And the most nearest number was '1'.

So the most nearest number and that which was specified in your request was granted, which is also the 'Univoter' Fame: 'The Unique Number One'

I think you'll have to check the registry to see which application is registered by default to open the htm/html files and launch that one. Another option in to use PInvoke. I think the function needed is FindExecutable from shell32.dll. See www.pinvoke.net[^] for more info on that.

System.Diagnostics.Process.Start("about:home");
works for me. but then iexplore is my default browser so i'm not sure about other browsers but maybe you can test?
If it' stuck, DO NOT pull harder!

I have a database query that will, for purpose of discussion, return either 1, 2 or 3 results. It could be any of these sizes.
I also have an array with 3 values in it. This is fixed.
I want to loop from i = 0 to 2 and compare a field's value from query row i to the value in array row i and do something if they match and do something different if they don't.
However, since I will always be looping 3 times and sometimes my query result will only have 1 or 2 rows in it, how do I check to see if the query row index exists before I go forward with the comparison?
Something along the lines of IfExists(mydata.Rows[0]) == TRUE is what I'm looking for. Any ideas? Thanks in advance! -Kari

store 1,2 and 3 in ArrayList.
Arraylist has one method to check value is contains or not.
Arr.Contains(mydata.Rows[0]);

if you are using SqlDataReader then you can use
SqlDataReader datareader = dataCommand.ExecuteReader();
int i = 0;
while (datareader.Read())
{
if (datareader.GetByte(0) == array[i])
{
}
i++;
}

I'm programming in c#.
I' have a problem with database insert procedure. I need read the last record in a table because I need the last key and insert a new record with key + 1.
For this procedure I open connection, select the last key, insert the new key and close conncetion.
The problem message is: There is already an open DataReader associated with this Command which must be closed first.
How to make this insert without leave the database? I can problem with the concurrent coneections.
Thanks.

You should close your DataReader object before executing the code that performs your insert.
BTW, this doesn't look like the most efficient way of adding a new record. You should consider wrapping the whole operation in a stored procedure that selects the latest key to determine the new key value and then inserts the new record with this key.

do you have an example of this operation? thanks
|
|

and you want to ensure you have sufficient locking on the table, for both the read and the write. If two people perform the same operation at the same time, they might both be given the same 'new' key.

Hello,
I'm hoping someone can help me out here.
I want to get started using DataGridView, but I've not actually managed to find any examples that fit what I'm trying to do.
What I want to do is very simple:
(1) I have a list of class instances thus:
<br />
List<MyClass> classList = new List<MyClass>();<br />
<br />
classList.Add(new MyClass("Fred"));<br />
classList.Add(new MyClass("Wilma"));<br />
<br />
etc
(2) I want each MyClass member of classList to be represented as a row in my DataGridView
(3) I want to show only a subset of the class parameters, for example:
<br />
public class MyClass<br />
{<br />
private string name;<br />
private string desc;<br />
<br />
private int anumber;<br />
<br />
public String Name<br />
{<br />
get { return (name); }<br />
set { name = value; }<br />
}<br />
public String Description<br />
{<br />
get { return (desc); }<br />
set { desc = value; }<br />
}<br />
<br />
<br />
<br />
public int Number<br />
{<br />
get { return (anumber); }<br />
set { anumber= value; }<br />
}<br />
}<br />
I understand that I need to set the DataSource parameter of my DataGridView to my data, in some way, but I don't seem to be able to get it to work. Do I need to do something to my classes to get it to work?
I think that sums it up. No SQL, nothing just a nice list of data that I want to display.
Can anyone help? Many thanks!!

Hi,
Use a binding source to bind your list and then bind the binding source to the data grid view.
dataGridView1.DataSource = bindingSource1;
dataGridView1.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader);
this.bindingSource1.DataSource = myList;
Thanks and Regards
Mahen

Please don't cross post. You asked this same question only two hours ago. It is rude to cross post just because no one answers right away.

To xmen_xwk,
you can use "Application.DoEvent();" at each loop.
