A button is always square, but you can change it's appearence by drawing it yourself (overriding OnPaint), and in the click event determine if the user clicked inside the visible part of the button.
Despite everything, the person most likely to be fooling you next is yourself.

Change Region of the control.
GraphicsPath path = new GraphicsPath();
path.AddEllipse(this.ClientRectangle);
Region = new Region(path);
And override the OnPaint method.

Hi,

can anyone helps me ?

BindingSource.Filter might help. Not sure though.
If you are using datagridview, then you have RowFilter property.

Have a look at the DataView class

I have a form view control in which i want to add an item in a dropdown list control on its databiund event.. But the code is giving me error .. can any body identify whats is the problem ?
protected void DropDownList1_DataBound(object sender, EventArgs e)
{ ListItem item = new ListItem();
DropDownList dl = new DropDownList();
item.Text= "Please select a driver";
item.Value="0";
dl = Ctype(FormView1.FindControl("DropDownList1"),DropDownList);
dl.Items.Insert(0, item);
}
|

|
|
You are programming using C#, not C++ or VB.
Use Convert.To...
|
|
|
|
|
CType is a VB command. In C# you just cast the reference:
dl = (DropDownList)FormView1.FindControl("DropDownList1");
When you declare the reference, don't create a new DropDownList object.
DropDownList dl;
Despite everything, the person most likely to be fooling you next is yourself.

What's the problem if you write the smtp mail address, i.e: without using 'dns.gethostname()'.
I am using the smtp to send emails, and it is working well with no problems, ans the following is my code:
MailMessage message = new MailMessage("FromAddress@yourCompany.com", "ToAddress@yourCompany.com",
"Application Alerts ", "Alert Email from your application System");
SmtpClient smtpClient = new SmtpClient("Your SMTP Name");
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = new NetworkCredential("The login Name", "Login Password","Your SMTP Name");
Attachment attachment = new Attachment("Attachment Path");
message.Attachments.Add(attachment);
smtpClient.Send(message);
Kind Regards

Hi guys, I am painting each Item for my listbox class and each item has an image with it. The problem is that when I load 20 or 50 plus items in my list the performance issues kicks in and my application takes lot of memory what can i do. Although, I am not dawing something speical in my paint event. Is listview better than listbox. I am happy so far with listbox functionality so far.
Thanks for answering

Have a look at something called VirtualMode, when this is enabled it will only draw those items which are currently displayed.

hi,
i building a application and i use the usercontrol to fill up my form.
My aplication as 3 levels (login usercontrol -> menu usercontrol -> edit usercontrols).
I put the menu usercontrol inside login usercontrol, and other usercontrols inside the menu usercontrol.
I don´t know if this is good pratice, for me work but is messy.
I do this because it´s the only way i know to call the usercontrols since they are inside (and belong) to is parent.(i don´t want to trigger usercontrols from a form).
Other issue is the scrolls (vertical or horizontal), i get some problems since the contents go off limites and the scrolls don´t appear. I set scrolls in the usercontrols.
Code is just works fine,yet , is more a design issue
can anyone help me here???

How can I change the size of icons on the desktop to press a button?. For example, I want to change the size 48x48. I have searched without finding an answer.
Thanks in Advance
really appreciate your help.

You can get the size using SHGetFileInfo but I don't think it can be set. There's a registry setting that applies to some versions of windows but not all (not vista for example).

I am writing a code to test a COM object and one of its functions has an infinite loop.
Basically my code should run this COM object function in a different thread, give it some time to finish but if it doesn't, terminate it.
However, I encountered the following problems:
1) Thread.Abort wouldn't abort the thread because you can't use .NET Thread.Abort to abort unmanaged code.
2) AppDomain.Unload wouldn't do anything because it tries to abort all the threads.
3) I tried using Marashal.ReleaseComObject and it resulted with:
"An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss."
By now the only current options I see is either using somehow the original Windows API to abort the thread or create a process especially to test the function. Both methods seem like a lot of overkill for what I'm trying to do.
Anyone has any ideas?

One idea: Write an unmanaged wrapper around the COM object that will stop it and return an error code if it times out. So a call to this wrapped object will always return.
Another idea: Get the source to the COM object, fix the infinite loop, and recompile it.
Another idea: Characterize the cases that result in an infinite loop, and avoid calling the function when this would happen. (I like this idea best.)
