in our listview we enabled sorting by clicking on the headers... now after you clicked on one of the headers and you clear the listview with lvTest.Items.Clear(); and add new items into the list view it gives an error: System.ArgumentOutOfRangeException: InvalidArgument = value of '1' is not valid for 'index'. Parameter name: index. I might be wrong but, is this because the listview still remembers the sortation and as soon as the new entries are loaded into the listview it sees that they are not sorted accordingly and displays this error message... If so, is there a way to say (right after the lvTest.Items.Clear(); section in our code) to reset the listview so that it won't sort in any way... (until you click on the headers again of course.) ???
Thank you in advance.

But there are more appropriate CP forums for this than the C# one. Try the general forum or the lounge.

I am designing a windows application with Visual C#. (beginner)
In this application I created a windows form "MenuSettings" with a tabcontrol for general & specific settings.
in one of the tabs 4 directory paths must be set. Visually this is shown as 4 rows where each row has a button to browse for a directory and a textbox to show the selected full directory path.
my questions are:
1)How can i make this button browse for a directory
2)Show the selected directory in the related textbox
3)and store the selected directory path as a variable
|
|
|
|
|
1) Search for FolderBrowserDialog
2) To get the selected folder from FolderBrowserDialog, use the SelectedPath property. To display this directory in a TextBox, use the TextBox's .Text property.
3) Create a string field in your class. Name it something appropriate. Set it equal to the SelectedPath you get back from the FolderBrowserDialog.

Does anyone know of a free (preferebly c#) auto-scheduler available?
I have a bunch of 2.0 console apps that need to be executed at different times of each day and I figured I'd look around for an auto-scheduler that's already available before I go and create one from scratch (why reinvent the wheel  ?)
Thanks.

Couldn't you just use the Scheduled Tasks utility that is in Windows? Seems to work well enough for me.

Hi All,
I have developed an ASP.NET application to send emails. I have followed the coding steps to create the application. But however, the mail is not getting delivered to the destination ID.
Can anyone help me in giving details about all the steps to be done before running the application. A sample application would be more helpful.
Thanks in advance,
Murali

What you have coded for the SMTP?
And what error it shows?
Did the Norton blocking you in sending the mails?

Hi,
Thanks for the reply.
If i set the SMTP Server name in the code as "smtp.gmail.com"(example), then i get the 'Could not access(CDO.Message) object' error message.
However, if i set it as 'localhost' then the email is redirected to the 'Queue' folder under the /Inetpub/mailroot.
Do i need to do any more settings?
Thanks in advance,
Murali

(1)Specify a valid mail server for the SmtpMail.SmtpServer property. If that property is not set, at least set it to 127.0.0.1. For example:
SmtpMail.SmtpServer = "127.0.0.1"
(2)If you are using "localhost" or "127.0.0.1" as the SmtpMail.SmtpServer, you may not have permissions to relay through the IIS SMTP Service. To allow access, open up the IIS Admin MMC. Locate the SMTP Virtual Server, and right-click, then select Properties. On the Access tab, click the Relay button. In the Relay Restrictions dialog, grant your IP address (127.0.0.1) to the Computers listbox. Close down all dialogs, and restart the SMTP Service.
(3)If you are using "localhost" or "127.0.0.1" as the SmtpMail.SmtpServer, make sure Anonymous access is allowd. To allow access, open up the IIS Admin MMC. Locate the SMTP Virtual Server, and right-click, then select Properties. On the Access tab, click the Authentication button. Be sure "Anonymous Access" is the only checkbox checked. Close down all dialogs, and restart the SMTP Service.
(4)The email address does not have a valid TO address. After iterating through the InnerExceptions, you may find this error message actually has to do with relaying. Try sending a test email to an email address that exists on the server specified by SmtpMail.SmtpServer. If you can send an email to that server, then it is a relay issue. Talk to your mail server administrator about letting your code relay through the mail server.
(5)Use a real FROM address that exists on the SmtpMail.SmtpServer. Do not use something like "asdf@asdf.com", or some other bogus address as your MailMessage.FromProperty. More advanced mail servers will catch this, and will deny relaying.
Regards,
Satips.

Hi,
I followed your steps. I send a sample mail to an ID existing in the local SMTP Server and the delivery was a SUCCESS.
However, if i try to send the mail to a different ID say hello@gmail.com, then i get a delivery fail message in the 'Drop' folder of the 'mailroot' folder.
Do i need to enable some options in the destination SMTP Server to recieve mails from my machine?
Thanks in advance,
Murali

I have made a COM DLL and facing this error
Error:Retrieving the COM class factory for component with CLSID {} failed due to the following error: 8007000e
can anybody solve this problem
Thanx
|
|
|
|

The error code implies that class was not registered. If you have a proxy/stub for the above CLSID then you need to register it on the machine.

hi!
i am building an application which inserts 100000 or more records in XML file and then retrieve those records when required in a datagridview control.
The retrieval of records is very slow, it takes 1-2 minutes in populating datagridview. First i thought it is because of XML, but today i came to know that it takes more than one minute for just creating 100000 rows of datagridview. I checked it by inserting 100000 empty rows in datagridview.
I tried to create rows in a separate thread but it gave exception that row cannot be inserted from a thread other than the one which created datagridview. i tried the technique available on msdn, which makes "Thread-Safe Calls to Windows Forms Controls" but it did'nt worked (may be i was not able to handle it)....
Now can any one please tell me how to get required result...? how can i add 100000 or more rows in datagridview control within 10 seconds...? is there any alternative way to do this?
Thanks in advance...
Regards,
Affan Ahmad Toor

Maybe 100,000 rows in a datagridview isn't what you really want. The user can only see a few of these at a time anyway, right? Just a thought.

Matt

You don't. You create a DataTable, or some other DataSet that holds all of your data, then bind the DataGridView to this data source.
I can fill a DataTable with 100,000 row of randomly generated data and show it in a DataGridView in less than 4 seconds.
