dataGridView.CurrentRow.Cells[0].Value will give you the value of the current row's first cell. Is that what you're looking for?

Hi,
This should work:
this.dataGridView.Rows[this.dataGridView.CurrentCellAddress.Y].Cells["dataGridViewTextBoxColumn0"].Value.ToString());
where dataGridViewTextBoxColumn0 is the column name desired.
For Sure

how to stop computer running process and start process using c#.
|
|
|
|
|
try System.Diagnostics.Start to strat external process.

Start and stop processes? Is that what you're asking? If so, look at System.Diagnostics.Process class.
|
|
|
|
|
you can start process using c# by this way:
using System.Diagnostics
.......
Process.Start("notepad.exe");
.......
Process.Start("cmd",@"/c mysqldump --user=root --password=123 mysql > c:\db.sql -t");//useful
.......
Process.Start("notepad.exe","c:\\record.txt");
.......
Process.Start("IEXPLORE.EXE","http://jnjx.126.com");
.......
Process.Start(@"C:\myFiles\MyApp.exe");
.....
and you can stop the process usingC# by this way:
//you can use the function
using System.Diagnostics;
..........
private void KillProcess(string processName)
{
Process myproc= new Process();
//
try
{
foreach(Process thisproc in Process.GetProcessesByName(processName))
{
thisproc.Kill();
}
}
catch(Exception Exc)
{
MessageBox.Show(Exc.Message);
}
}
//you can call this function like :KillProcess("iexplore.exe");

Hello everyone,
Before retrieving a page from Http, it is possible to know what are the content type it will return? e.g. image, html, text?
My initiative is to know the content type before retrieving the content, since if the page contains image, video or audio, I will not retrieve the content to save space and reduce risk.
Any ways to know content type returned without actually retrieve the page?
thanks in advance,
George

The content type should be in the HTTP headers, you will need to get that at a minimum (only a few bytes of plain text).
|
|

|
|
Thanks leppie,
Which API could be used in C# to retrieve only the content type for a page without retrieving the whole page content?
regards,
George

how to write select quary sql server compact 3.5 ("SELECT * FROM Table1 WHERE name" is wrong)
|
|
|
|

Try specifying the fields you want to select, rather than *. SQL compact may force you to specify the fields. (No idea about this, but just a thought.)

I am playing with a program where I will need to have random image/images populated in either picture boxes or labels
I know how to create random numbers with the random next function but for the life of me I can NOT figure out how to create random images
I have all my images in three different imagelist (separated by category)
I have been looking online for tutorials but I am coming up empty handed…
Thank you for your time

you can
Try this[^]
this is asp.net example, you can use this concept in windows application also.

A Customer can have multiple Products and a Product can be assigned to zero to more Customers
But, there are some items (such as BasePrice and DefaultPrefix) that are implicit to a customer-product relationship.
In the database this can be modeled as
Table Customer with Columns CustomerId, Name, etc.
Table Product with Columns ProductId, Name, etc.
Table CustomerProduct with Columns CustomerId, ProductId, BasePrice, DefaultPrefix, etc.
How would you model this as Domain Objects?
All I could think of is
Customer
..CustomerId
..Name
..AssignedProduct[] Products
Product
..ProductId
..Name
..Customer[] Customers
AssignedProduct : Product
..Customer Customer
..BasePrice
..DefaultPrefix
But that doesn't strike me as too slick (an Assigned Product has a Customer and a Customers[]???) and as this simplified example gets closer to what I actually have to model, this design starts to have problems among which is that NHibernate can't model some of this stuff

Hi.
Do you really need the customer relation in the product object?
If your app has a customer point of view, my suggestion would be:
Customer
..CustomerId
..Name
..AssignedProduct[] Products
Product
..ProductId
..Name
AssignedProduct : Product
..BasePrice
..DefaultPrefix

The short answer is no, multiple Customers can have instances of the same product (though in this case, different AssignedProduct) so it should be possible to navigate from Product to all Customers that are assigned it. Also, I've tried that set-up already and it has some more esoteric disadvantages.
The long answer is that this is a simplification of slightly more complicated schema. Basically, imagine the relations between Location, Customer, Product, and Container for a company which has multiple Locations at which it rents out Containers for Customers to store Product in. A Customer can exist at multiple Locations and a Location can have multiple customers (again, the existance of a relation entails additional data); a Customer can have mutliple Products and a Product can be assigned to multiple Customers - which have to be at a location to have a product assigned. Finally, each Product that is assigned to a customer can be stored in zero or more Containers.
The database in the meantime is not completely normalized, and since it is legacy, I cannot change it. It looks something like this:
Location
Customer
Product
Container
CustomerLocation with fk to Location, Customer
ProductCustomer with fk to Product, CustomerLocation
ContainerProduct with fk to Container, ProductCustomer
So, in addition to the set-up I postulated being a little awkward, it is actually currently impossible for me to map with NHibernate.
