My first guess would be to iterate over the array and check the values, but of course that may be to simple for you to figure out.

loop cant help because, may be I'm missing something

for i=0 to array.length-1
if array(0) = 1 then
check = true
else
check = false
end if
next

this doent work for me because if the last element is 1 then the check(boolean variable)becomes true while it is possible that other elements for example first one is not equal to 1. but I need to make sure are all of them (all elements) are equal to 1 or not.

Help please

Yes, you are. This is a good exercise to weed out the pretenders from the performers. Which are you?

Anybody else could help?

We are here to help, not give you everything. This is a very simple exercise in logic, don't get upset if you are not up to the task.

Read the previous posts carefully, there is no blame being assigned

You are still new here so I would hold the attitude if I where you.

You should probably encapsulate this into a function and return false for the first one that does not match and return true if you get to the end of the array without finding one that does not match.

Incidentally, if you are using .NET 3.5, the built in All extension method from LINQ will do just that.

Morning CPians, dig me out here Smile | :)

I need to send an E-mail from my app through the default E-mail setup on a client system. (invoices and order confirmations, exciting stuff)

I have learned through some Googles that MAPI used to do this (no I haven't tried, it looks pretty old), then MAPI was replaced by System.Web.Mail, which has now been replaced by System.Net.Mail. Great, BUT, these .NET replacements both need to be told the E-mail server's address and/or domain, which my users will definitely not know.

The Outlook automation assemblies look like an easy option, but I'd just as soon not limit myself to Outlook, or move outside .NET

Is there some way to have System.Net.Mail just send the mail through whatever default E-mail settings exist on a user's machine?

Perhaps I can look up the E-mail settings somewhere? Magically impersonate the user?

Ideas? Guidance?

Hi,

I use MailMessage, MailAddress, and SmtpClient classes, and keep some strings as settings, including the mail server name (which SmtpClient constructor needs).

I know of no way to solve it without settings for all possible situations.

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

If you need it to actually display the message in the users default email client (like Outlook, Live Mail, etc.) you can use some interop to MAPI, but you need to be very careful about resource leaks. Keep in mind that this isn't officially supported and is actually not recommended, but I think as long as you are careful and only use it to open a mail message it's safe.

Otherwise, you can use the built-in .NET classes but you will need to ask the user for the email server. You can save that information as a setting somewhere so you only need to ask for it once, but there isn't a way (as far as I know) to automatically get that information.

bug in DataAdapter's ContinueUpdateOnError property

Hi

I am facing one proble with DataAdapter.

Problem is I have multiple rows in my DataTable and i am going to save it.

I have set DataAdapter 's 'ContinueUpdateOnError' property to true

so that i can continue on to next row.

I have 6 rows and i get some check constraint error from DataBase on my 4th row.

and i have called whole operation through .Net TransactionScope Class.

because of error i will call Dispose method of TransactionScope Object.

so actually no row will be saved.

but what happened , the next 2 rows after 4th row , that is 5th and 6th rows got saved in DataBase !!!!!!! ????????????

strange .........

please

if you have some idea reply me.

Thank you.

you can see my code

..
..
..
..
DataAdapter daWOStdVal = new DataAdapter();
..
..

daWOStdVal.ContinueUpdateOnError = true;

daWOStdVal.RowUpdated += new SqlRowUpdatedEventHandler(OnWOStdValRowChng);

daWOStdVal.Update(dtSCStdVal);

..
..
..

Regards

Why would you set ContinueUpdateOnError to true if you don't want it to continue updates on error? Rather than call dispose why wouldn't you just set a flag to call rollback when you are done processing rows? It seems you are doing everything you can to make sure it isn't a real transaction.

Missing .NET configuration tool in win7

Dear All:

I installed VS 2008.NET in my computer which is Win7 System. I tried to find the .NET configuration tool snap-in but I couldn't find either the mscorcfg.msc or the administrative tool from the start menu and control panel.

I read the article on the MSDN website but none of the method mentioned there solves the problem.

Most importantly, it seems that the file mscorcfg.msc is not installed on my computer.

Besides, I tried to install the framework SDK 2.0 but it doesn't solve the problem

Could anyone point me how to find the configuration tool please?

Thanks

SDK 2.0 is the way to go.

There is an updated article on MSDN[^] for .Net 3.5 which is what you will have.

Hope this helps.

Hello,

I would like to ask if how do allow 2 input only in a textbox
after entering decimal.

Manas Bhardwaj3-Mar-10 23:55

use regular expression validator and in the validation expression specify this: (^\d*\.\d{2}$)

Hello,

Would you mine if could you give me some sample of using the format validation
I have tried using lastindexof but my code doesn't work unless if I enter
"." at begginning of my textbox.
my code is this

Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles  _
               TextBox1.TextChanged

        If TextBox1.Text.IndexOf(".") Then
            TextBox1.MaxLength = Val(TextBox1.TextLength) + 2

        End If
End Sub

Thanks,

He's already given you the regular expression you need to use. Why haven't you used that? The code you've got here isn't validation, it's input constraint - which is a different thing altogether. What happens if you put in .AA (hint - your code thinks it's valid, but it patently is wrong)?
