C# introduces a new concept known as Indexers which are used for treating an object as an array. The indexers are usually known as smart arrays in C# community. Defining a C# indexer is much like defining properties. We can say that an indexer is a member that enables an object to be indexed in the same way as an array.

{
get
{
 // Get codes goes here
}

How to get the innerHTML from Label and update it.

While I was working on a particular web application, I had to have the account number displayed when there was a chagne is dropdown menu. Now, all that worked well with a bit of a javascript.

But, the real issue was after the button was pressed , the page it dispalyed still retained the selected drop down item but the account no. on the label was gone and was being displayed as blank.

Hence, after a bit of the research I found out the easiest way to solve this issue was via implementing another javascript on ButtonClick.

Eg.

<br />RegisterStartupScript("MyScript", "<script language="javascript" defer="defer">document.getElementById('" + lblAccountNofrm.ClientID + "').innerHTML = frmAcc[" + lst_fv_1.SelectedIndex + "][1];</script>");<br />

OR//
<br />ClientScript.RegisterStartupScript(Page.GetType(), "Update the second label", "<script language="javascript" defer="defer">document.getElementById('" + lblAccountNoto.ClientID + "').innerHTML = frmAcc[" + lst_fv_2.SelectedIndex + "][1];</script>"); <br /></texarea><br /><br /><br />


Please note, the mistake the people gerenally make is to put your script before the textbox.

When page load , javascript try to execute the code by do not know yet the textbox control and the div.

To be sure that a javascript is executed when all your page is loaded (or DOM built) add defer="defer" on javascript tag

The filename, directory name or volume label syntax is incorrect in VS2005

I have been trying to start a new project in Visual C# Studio 2005 Express and keep getting the error:

the filename, directory name, or volume label syntax is incorrect. (Exception from HRESULT: 0x8007007B)

Solution : -

it appears that you cannot create a project within a path that has an ampersand (&) in it, which my original projects path did. In Tools/Options/Projects and Solutions/General, I selected the "Show advanced build configurations' option. This allows me to select the project build location on creation of a project, and I am now able to ensure it does not try to create in the path with the ampersand in it.

int i = cmd.ExecuteNonQuery() + SELECT statement

I spent hours trying to figure out why the code wasnt' returning the correct value.
No matter what I do I was only getting -1.

Finally, after few research and all that I found out that SELECT and cmd.ExecuteNonQuery() is no t the way to go.

but instead a simple solution would be to use ExecuteScalar().

But the catch with using ExecuteScalar is to use Select Count(*) from ... instead of Select * from ...

Hence, finally was able to do this by using
Select Count(*) form ...

and then
int i = (int)cmd.ExecuteScalar();

An internal error occurred. This can be either the user profile is not accessible or the private key that you are importing might require a cryptograp

It was because I added the "Network Service" security user as the permission to the RSA folder, which wasn't there before. Once, I remove the permission it was back to normal.
