I have made a program to play video file in directx (directx.AudioVideoplayback)! It worked well ! But I couldn't find the way to handle the video.owner !
when I did set the video.Owner = (name of my panel); I wanted to set video to full screen mode by double click on the video (in bool property video.FullScreen).
I tried to add Double Click EventHandler to my panel or video.Owner but It didn't work !
How can I do this ? Any ideas ... ?

I don't think that you coudl do that in Javascript... meaning: I don't think you could do that at all.
On the other hand, once recieved on the server side you could check the pic before saving it into the database (and write a little confirmation / error message).
To test on the server side:
Bitmap bmp = new Bitmap(new MemoryStream(buffer));
if(bmp.Width > 100 || bmp.Height > 100)
....

After much thinking you could submit the data not through an FileUploadInput but through an ActiveX / JavaApplet, in which case you could do all the test you like....

Hello,
I am trying to execute the following code from a background worker's DoWork Event Handler and getting the error :Cross Thread Operation etc..etc... Can you kindly show me some ways to do this work. The following code does Extract Text from a MS word document file.
string textData ;
try
{
Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.ApplicationClass();
object nullobj = System.Reflection.Missing.Value;
object file = fileName;
Microsoft.Office.Interop.Word.Document doc = app.Documents.Open(ref file, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj, ref nullobj);
doc.ActiveWindow.Selection.WholeStory();
doc.ActiveWindow.Selection.Copy();
IDataObject data = Clipboard.GetDataObject();
textData = (data.GetData(DataFormats.Text)).ToString().Trim();
doc.Close(ref nullobj, ref nullobj, ref nullobj);
app.Quit(ref nullobj, ref nullobj, ref nullobj);
}
catch (Exception error)
{
MessageBox.Show("Error Extracting Resume Text : " + error.Message);
}

My guess is that the code that you're running happens to raise an exception and hit the line that displays a MessageBox. That operation is not allowed on a background thread so that's probably where it yells at you.
Try commenting out the "MessageBox.Show.." line and see if you still get that error.
Have you verified that yet?!

Hi,
Thanks for the reply. Actually I did not have problem showing Message Box in background worker thread. The error showing because it is acessing MS word file, openning it, selecting the text, copying the text and then a string is getting value of the selected copied text. And this selecting the text is being prohibited by background worker. OR can you show me some other way to extract TEXT from MS Word ? Even if I find a free command line MS word to text converter, I will be happy. I will use Diagnostics.Process in that case/
Thanks

Well, using COM Interops can be tricky. Whenever you work with COM automation you have to be mindful of the threading model of your application. Have you tried running your code in the main thread (not in the background worker thread)?
If so, and it works.. try creating the secondary thread manually instead of using the BackgroundWorker object. That may help.
Other than that, I'm running out of good ideas :p

Hi,
Thanks for your reply. Yes, This code is working excellent without Background Worker ( I mean, within Main Thread ). So, I will try using manual thread. I thought Background worker and manually created Thread are exactly same thing.
|
|
|
|

They are similar but as far as I know, the Background Worker thread object implements some extra functionality to properly marshal the calls between the threads. The funny thing is that it's supposed to fix just the type of problem you were experiencing. I'm surpized..
As I said earlier, I think you need to delve deeper into the details of the COM+ threading model and interacting with it from the a .NET mannaged thread.

Hello,
I am trying to create an e-mail application. I have created a simple mail application in win forms. The user will put in the fields and click the send button.
I am not really sure how an e-mail application works. But if send an e-mail to my e-mail account i.e. steve1_rm@hotmail.com. I send the e-mail. However, I never receive the e-mail that I send using this mail application. The application works ok, and there are no run-time errors. Is there something I need to do, to be able to send this to my hotmail, yahoo, or gmail e-mail accounts.
The code I have used is below. This has been written in C# Visual Studio 2005.
Thanks in advance
<br />
using System.Web.Mail;<br />
<br />
private void btnSend_Click(object sender, EventArgs e)<br />
{<br />
try<br />
{<br />
MailMessage aMessage = new MailMessage();<br />
aMessage.From = txtFrom.Text;<br />
aMessage.To = txtTo.Text;<br />
aMessage.Cc = txtCC.Text;<br />
aMessage.Bcc = txtBCC.Text;<br />
aMessage.Subject = txtSubject.Text;<br />
aMessage.Body = txtMessage.Text;<br />
<br />
if (txtAttachment.Text.Length > 0)<br />
{<br />
aMessage.Attachments.Add(new MailAttachment(txtAttachment.Text, MailEncoding.Base64));<br />
}<br />
<br />
SmtpMail.Send(aMessage);<br />
<br />
MessageBox.Show("Message sent to " + txtTo.Text, "E-mail Program", MessageBoxButtons.OK, MessageBoxIcon.Information);<br />
}<br />
catch (Exception ex)<br />
{<br />
MessageBox.Show(ex.Message.ToString());<br />
}<br />

You need an SMTP server. If you don't have one installed on the computer you are running, specify the address of the SMTP server to use in the SmtpServer property in the SmtpMail class.

I recently got bored and made an e-mail aplication. Using my ISP's mail server worked for me. Also I noticed that you are using System.Web.Mail namespace. In C# 2.0 this is obsolete. System.Net.Mail is the one that the compiler reccommends, however it is not required.
Ex.
using System.Net.Mail;
using System.Net;
...
try
{
using (MailMessage message = new MailMessage("me@hotmail.com", "you@gmail.com", "Test", "This is a test"))
{
message.IsBodyHtml = true;
SmtpClient mailClient = new SmtpClient("smtp.execulink.com");
mailClient.UseDefaultCredentials = true;
mailClient.Send(message);
}
MessageBox.Show("Message Sent");
}

Hello
I have just found some useful information. I have configured the IIS smtp virtual server.
In the general settings l have add my IP address.
In the access tab, click rely button and granted access to my IP address.
I have added this code:
Code:
<br />
Smtp.MailServer = "localhost"; <br />
or<br />
Smtp.MailServer = "127.0.0.1";<br />
But l am still getting the same error message "Transport failed to connect to server".
I have added this code:
<br />
Smtp.MailServer.Insert(0,"localhost");<br />
This time I don't get the error message, but did not receive any e-mail to my yahoo account.
I am using winforms not asp, not sure if this makes any difference.
Any ideas on how to solve this.
Many thanks,
Steve

Smtp.MailServer = "mail.hotmail.com";
Smtp.MailServer = "mail.gmail.com";

Be advised that most "Freemail"-Providers do not accept messages which have conflicting Sender-Address and Sender-IP/Hostname information.
That is, they would drop a message from test@hotmail.com if the server sending the message does not belong to hotmail (e.g. sender-address is "test@hotmail.com", sending server is "mail.gmail.com").
Be sure to use the SMTP-Server your Mail-Provider has given your for that address.

Hello,
I made the changes to the SmtpMail.SmtpServer = "mail.hotmail.com";. My listing for sending the code is illistrated below. But still does not work. I am sending the e-mail to my hotmail account steve1_rm@hotmail.com, but never gets there.
<br />
MailMessage aMessage = new MailMessage();<br />
aMessage.From = txtFrom.Text;<br />
aMessage.To = txtTo.Text;<br />
aMessage.Cc = txtCC.Text;<br />
aMessage.Bcc = txtBCC.Text;<br />
aMessage.Subject = txtSubject.Text;<br />
aMessage.Body = txtMessage.Text;<br />
<br />
if (txtAttachment.Text.Length > 0)<br />
{<br />
aMessage.Attachments.Add(new MailAttachment(txtAttachment.Text, MailEncoding.Base64));<br />
}<br />
<br />
SmtpMail.SmtpServer = "mail.hotmail.com";<br />
<br />
SmtpMail.Send(aMessage);<br />
<br />
MessageBox.Show("Message sent to " + txtTo.Text, "E-mail Program", MessageBoxButtons.OK, MessageBoxIcon.Information);<br />
Is there something I am doing wrong, or something I am not doing.
Thanks in advance,
Steve

Hello
I have found some information on another post that told me that you cannot directly send e-mails from the outside to hotmail, yahoo, etc. In order for you to do this you have to send a username and password to be authenticated for hotmail, yahoo, etc. I thought it was possible to send e-mails to these accounts.
I did what you suggested and my code is similar to yours. I deleted the mails from inetpub/mailroot/queue and restarted IIS. But still did not work.
Any other suggestions about this I would be most grateful.
Thanks,
Steve

I am interested in playing around with some IO in C#. Could someone point me out to some articles about IO with a USB port in C# 2.0?
Thanks,
Sean

The only thing I've come across is IC#Code's #usblib
But I don't think it's been updated in a long time.
Another alternative is to use the SerialPort class and specify a usb port to open (this works in the old MSComm control). I'll try and remember how the ports are named , this will allow you to use the USB port like a Serial Port
