Hello,
I have created an email application.
Error Message: The remote certificate is invalid according to the validation procedure.
But keep on getting this error message each time I try and send. The remote smtp is working ok as that has been tested using outlook, so i think something to do with my code, or something i have not done.
I have also tested this code using gmail's smtp server:
gmail@smtp.com using my gmail account details. Sent e-mail ok.
The code i am using to connect to a remote server is this below. can anyone tell me if I have done something wrong.
<br />
private void button1_Click(object sender, EventArgs e)<br />
{<br />
MailAddress msgTo = new MailAddress("steve1_rm@hotmail.com");<br />
MailAddress msgFrom = new MailAddress("Steve1.rm@gmail.com");<br />
MailAddress msgSender = new MailAddress("steve1.rm@gmail.com");<br />
<br />
MailMessage mailMsg = new MailMessage();<br />
mailMsg.To.Add(msgTo);<br />
mailMsg.From = msgFrom;<br />
mailMsg.Sender = msgSender;<br />
<br />
SmtpClient client = new SmtpClient("xx.xxx.xx.xxx", 25);<br />
client.Credentials = new System.Net.NetworkCredential("xxxxx@smtp.xxxx", "xxxx");<br />
client.EnableSsl = true;<br />
<br />
try<br />
{<br />
client.Send(mailMsg);<br />
}<br />
catch(SmtpException ex)<br />
{<br />
MessageBox.Show(ex.Message);<br />
}<br />
catch(Exception ex)<br />
{<br />
MessageBox.Show(ex.Message); <br />
}<br />
}<br />
Many thanks if you can help me with this problem,
Thanks,
Steve

Hey guys,
I'm quite new to C#. I am using Visual C# 2005 Express which I downloaded from Microsoft.
I have searched for a good 30 minutes, and I couldn't find anything which was helpful.
What I want is, when you press control + u another Form comes up. I have tried this:
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.ControlKey && e.KeyCode == Keys.U)
{
username myUsernameDialog = new username();
myUsernameDialog.ShowDialog();
}
}
However, that doesn't work. I really do not know where to go from here.
Thanks in advance,
- Gordon

hi
This is working. Change the control condition as given below:
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Control == true)
{
if (e.KeyCode == Keys.U)
{
Form2 a = new Form2();
a.ShowDialog();
}
}
}
If you want to thank me for my help, please vote my message by clicking one of numbers beside "Rate this message". Thank you. Harini

Hmm...
That doesn't work for some reason :S
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Control == true)
{
if (e.KeyCode == Keys.U)
{
MessageBox.Show("Yay!");
username a = new username();
a.ShowDialog();
}
}
}
It compiles/runs fine, but it just doesn't work. Do you know what the problem could be?
Cheers!
p.s. I voted 4/5.

Hello,
You have to set the "KeyPreview" property to "true" at your Form?
this.KeyPreview=true;
All the best,
Martin

I have a user control on my asp.net page . This user control has 4 buttons on click of these buttons a new page opens below these user controls. Now after the page is opened and i click anwhere on the page the focus goes to 1st button in user control irrespective of the button i click. Hence when my user hits enter every time the first page opens. I have checked the code and there is no focus set for this in my code. I dont understand why it is happening. I wnt that when the user select a button the focus remains on it even if i click on the page.could some body help me..... I require it.............

Please don't use all capitals. I lost heart halfway through and stopped reading what you had written because it is just too much to read. Please use mixed casing.

Do you use a postback to open the page below? If you do, then this is the cause of your problem, because ASP.NET doesn't maintain state like this between roundtrips. You could always use JavaScript to set the focus automatically.

if you are building any desktop base application then don't write anything in the Text property of Form.

Why would you want to do this? This is the "holy grail" for virus writers.
You should never prevent the user from being able to kill your process because you can't foresee every eventuality, and if your application becomes a memory hog for some reason the user may want to kill it.

I want to make a secure erase file tool using c#. I know that there are some rules to be followed when making such a tool(overwriting the file many times,renaming, truncating and than deleting), but i didn't manage to find a document or some site where all this is explained (all i found so far are tons of programs that offer me secure delete solutions, and some well written but old linux document on this matter ... from 96 till now thing have changed a bit ...). Can any of you offer me some recent documentation, or pointers on this ? Thanks.

hey,
i am developing an application, and i need to use something like voice recognition, but this time i want to recognize a sound in a video file, so i thought that i might write the code first to convert video formats to sound formats, and then use speech sdk to recognize that sound.
please could anyone tell me, how can i convert the video formats to sound, through C# code, or if there is another way to recognize that sound in video files.
waiting fro reply
thanx in advance.

There's an excellent article here on CodeProject by Michael Dunn about intercepting NM_CUSTOMDRAW messages to modify the look of a ListView -- not as involved as OwnerDraw, though, which is nice.
Here's the link: http://www.codeproject.com/listctrl/lvcustomdraw.asp[^]
Unfortunately, the article is not written for C#. I was wondering how to hook into the message stream to intercept and act on NM_CUSTOMDRAW messages in C#. I asked at the article, but Michael does not know.
I've seen the example code in the C# help on using OwnerDraw, but that of course requires handling almost all of the drawing chores. Can we, in C#, hook into the message stream and just do custom draw type stuff like described in Michael's excellent article? If so, how? What event handler do I need? Where do I declare it? Stuff like that. Or do I have to create a ListView derived class and override the WndProc? (which I'd rather not do if I can avoid it)

Unfortunately, you do have to derive from the class and subclass the window. Subclass the ListView[^], and handle the WM_NOTIFY[^] message. When WM_NOTIFY is received, convert the memory that the lParam parameter points to to an NMHDR[^] instance, and check its code field. If it is set to NM_CUSTOMDRAW, convert the same memory to an NMLVCUSTOMDRAW[^] structure, and work with it as described in Mike's article.

Wow! One of the best answers I've received here at CodeProject.
Thanks a bunch for the links.
I'll work through it and see what I can do.
Thanks again.

Hmm. I'm sure this is a totally rookie problem.
I've done my fair share of casting in C++, but I'm pretty new to C#.
How do I cast the lParam to my NMHDR struct in C#?
In my class (which per the link you supplied is derived from NativeWindow), I have NMHDR defined:
private struct NMHDR
{
IntPtr hwndFrom;
IntPtr idFrom;
UInt32 code;
}
Then in the overridden WndProc, I have:
if (m.Msg == WM_NOTIFY)
{
}
And since I am pretty new to C#, I don't know the syntax for this casting.

OK. I answered my own question.
In case anyone else out there runs into this sort of problem, here's what I found (and it seems to be working):
if (m.Msg == WM_NOTIFY)
{
NMHDR nmHdr = new NMHDR();
nmHdr = (NMHDR)m.GetLParam(typeof(NMHDR));
if (nmHdr.code == NM_CUSTOMDRAW)
{
Debug.WriteLine("Got here.");
}
}
But now I have a different question (there's always something):
Where can I find all the info on the struct.s I need (including, but not necessarily limited to: NMHDR, NMCUSTOMDRAW and NMLVCUSTOMDRAW)? I can find them easily enough by searching MS KB, but is there a file somewhere that I can cut and paste from or just include in my code that already has all of this stuff defined (in C#)? Manually coding all of the structs is kind of a pain.
Thanks.

You may find what you need at PInvoke.net[^], but they don't have all of the Win32 structures defined.
