I want to write some property item to image. Though I could not do it. But I can edit any currently added property. So I want to know is there are any property item I can use for my purpose? Here are some Id I am getting:
Id:271
type 2
Id:272
type:2
Id:274
type:3
Id:282
type:5
Id:283
type:5
Id:296
type:3
Id:306
type:2
....
etc.
My question is can I use any of the currently present property?
Sounds simple i think
<img id="myimage" data-id="data you want to pass"/>
if you want to add attribute from c# then
ddLedger.Attributes.Add('data-id','yourvalue');
So you want to access this property at backend c# then
string aa=myimage.attributes("data-id");
in string aa you will get your data....
and in jquery
$('#myimage').attr('data-id');
Now if you want to add it at run time then like this
$('#myimage').attr('data-id','your id added');

I want to create application in WPF wchich will scrape information from webpage
I read link to the page from text box at the top
I want to extract company name from h6
I don't understand that format:"//h2[#class='card__title mdc-typography--headline6']". I could't find documentation abot meaning # [] etc. to create another filters to scrape other data for example phone number from tag.
The #, //, ... represent abbreviated syntax for XPath selectors.
#abc is short for attribute::abc
// is short for /descendant-or-self::node()/
So, in other terms, your current query //h2[#class='card__title mdc-typography--headline6'] represents the action of finding the first descendant- or self-node that has a class attribute of card__title mdc-typography--headline6.

I don't really know what you need, but if the quantity is between the two | you can use this code :
(?<=\|)(.*?)(?=\|)

If quantity is between the | and the , use this:
(?<=\|)(.*?)(?=\,)

I've encountered sometimes code like this and I am kind of new to programming. I want to find out what's the meaning behind those objects or data type enclosed in parenthesis.
(int)
(datagridview)
(form)
If you see something like this it's called a cast. It's used to explicitly convert a data type to another data type.
double pi = 3.14159;
int my_int = (int)pi;
See this description on casting for more details.

How do I have it check my variable before allowing a click.
Example :
_StartControl.Click += new EventHandler(StartControl_Click);
I only want them to be able to do that if my variable "isValid" is equal to 1.
I'm not very good at forms.. Have always learned just console apps.
You can check the value of your isValid field inside StartControl_Click method. If the value is 1, you can allow the method to proceed, if it's not 1, you can simply return from the method before anything gets executed.
You can do it like this.
if(isValid==1)
_StartControl.Click += new EventHandler(StartControl_Click);

I'm using webBrowser control in winform app C# FW4.0, and I would like to find all the elements that their class attribute contains some value. Is it possible?
You can do this, but it will take some work on your own.
An example on how to find all a tags with class show1 should help you find what you need. Here is an excerpt from the example there
var links = webBrowser1.Document.GetElementsByTagName("a");
foreach (HtmlElement link in links)
{
if (link.GetAttribute("class") == "show1")
{
//do something
}
}
