Could you give us some information on the exception? what type? what was the error message?
Also, could you post some your code (the 10 o 15 lines where you send the email)? From what you say it's hard for us to know the problem.

I just followed the sample code in the MSDN library for Visual Studio in 2005.
The exception:
System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: U
able to connect to the remote server ---> System.Net.Sockets.SocketException: An est
blished connection was aborted by the software in your host machine

I just want to send a test to my network mail server not local machine.
Thanks.

I haven't seen the code, but I would guess you are trying to use localhost as your SMTP server when the service has not been enabled. Could you post the code?

I have run into this problem. In my case, our Virus software was preventing the mail from being sent. Our administrator had to allow mail coming from my machine for the vshost.exe process.

I'm having a problem with a graphics control I'm working on. It seems that the Graphics.DrawImage method is clipping a half pixel off of the image, and then shifting it up and left by that half pixel. This can usually only be seen when zoomed in 2-4x or more, but now that I know what to look for, I'm seeing it happen even close to 1x with certain images. The following image shows the extent of the issue when zoomed in significantly - the green lines you see are where the bounds of the bitmap should be: odd_image.jpg[^]
The graphics object that gets drawn to is from a bitmap that gets created on the fly depending on the size of the control and the objects in it. All graphics properties are set to the default except for the following:
g.InterpolationMode = InterpolationMode.NearestNeighbor
g.PageUnit = GraphicsUnit.Millimeter
and there is a translation applied (though removing it did not affect the problem).
I tried changing to the PageUnit to various values with no change, I also messed with PixelOffsetMode, CompositingMode, CompositingQuality and SmoothingMode, trying various values to no effect.
I've done several searches in here and MSDN and found nothing that fixed the problem, or even hints that there is one. Has anyone seen anything similar to this, or have any ideas to try?

Setting the PixelOffsetMode to "HighQuality" worked for me before, IIRC.
|
|
|
|
|
That did it alright. I swore I tried that yesterday - but I tried a million combinations before giving up and posting, that one must have slipped through, or maybe it didn't work with some other setting I had at the time.
Whatever, works now - Thanks!

I have written a component in C# with the following structure:
Data is loaded from database into a DataSet
"Record" class wraps each DataRow in the DataTable I have loaded. i.e. the properties on the object read/write the columns in the DataRow.
"Records" class inherits from CollectionBase and is a colleciton of "Record" objects.
The problem I have is how to sort the Records collection. I am currently doing this by sorting the underlying DataView which is held in the "Records" object. However, I then had to write some messy code to sort the Records collection class based on the order of the view. It works, it's not really slow, but I just feel there must be a much better way of approaching this.
Does anyone have any suggestions?

You can use ORDER BY ColumnName keyword in query.
Know Yourself Then Grow Yourself.

I am aware of the ORDER BY command in SQL. However, I need to sort the data after it has been retrieved by the client application and hence this will not help.
I was wondering if I need to use the CompareTo or Equals methods which are on the base object interface to do this?

Hi,
i would like to create a simple control for smart phone (cf2.0) that changes its background color depending upon whether it is focused or not. i have the following code.
class mylabel:Control{
protected override void OnGotFocus(EventArgs e){
base.OnGotFocus(e);
this.BackColor = Color.Red;}
protected override void OnLostFocus(EventArgs e){
base.OnLostFocus(e);
this.BackColor = Color.White;}
}
The problem is it can get focus (and changes its bg color) but it seems it does not loose focus. if i inherit LinkLabel instead of Control then it works fine.
What could be wrong? i would really appreciate.
regards,
rnv

Well, I've never programmed for CF, but the recommended way to determine when a control gets focus AFAIK are the Enter and Leave events.
However, why are you deriving from Control? Unless you are creating a new control from scratch, if you want to add this functionality to existing controls (text boxes, buttons, and so on) I would rather subscribe to the events for the controls. You could write a little class that given the control reference in the constructor, it would subscribe and handle the events. Then you could apply it to any control with just one line of code.

Hello!
In C++ we could do m_listView.SetRedraw(TRUE) in order to block repainting of the list view control. Add some items to it and call m_listView.SetRedraw(FALSE) to allow drawing again. This was pretty fast.
Now my question: is there an equivalent to this in .NET? I've looked at the member list of ListView, but didn't find one that does that. Have I overlooked something?
Note: I do NOT want to use a virtual list view.
Thanks in advance and best regards

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Yes, you have ListView.BeginUpdate() and ListView.EndUpdate().
