Hello experts...
I am developing an game using desktop application in C#.net 2005.
In that I have 3 forms (No MDI form).
I want to show form1 then form2 and then form3.
But if user press cntl+f4 key form goes close and second forms show
how to prevent this..?
I also have close button on each form.
Regards

Handle the Closing event on the form, the event arguments will have a Cancel property. Set that Cancel property to true.
|
|
|
|
|
1. Set the form's KeyPreview property to true.
2. Add a KeyDown event to the form like this:
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyValue == (int)Keys.F4 && e.Modifiers == Keys.Control)
{
e.SuppressKeyPress = true;
}
}
That's it.
Hope it'll help.

Hello DannyAdler sir,
This is working fine. Thannks for the help.
I only have one question .. Is their any problem to using that code.?
I don't think so... But if any, please tell me points to be remember
while using this code.
Regards

Two things I can think of:
1. After setting the KeyPreview property to true, ALL the key-down events will first go through this function.
2. The CTRL-F4 will never work on that window, as long as the key-down is supressed in the if statement.
Just to keep in mind.

Hi all,
Trying to send mail with System.Net.SmtpClient, using very simple code
just for testing:
SmtpClient smtp = new SmtpClient("mail.server.com", 25);
smtp.Credentials = new
System.Net.NetworkCredential("user", "password");
try
{
smtp.Send("sen...@server.com",
"recipi...@server.com",
"Subject",
"Body");
MessageBox.Show("Mail Sent!");
}
catch (Exception ex)
{
txtErrorMsg.Text = ex.ToString();
}
BTW, the mail.server.com is not mine, it's an ISP mail server.
On my local machine, this code works fine and actualy sending the
mail.
BUT, on my remote server the same code produces the exceptions as
follows:
System.Net.Mail.SmtpException: Failure sending mail. --->
System.Net.WebException: Unable to connect to the remote server --->
System.Net.Sockets.SocketException: No connection could be made
because the target machine actively refused it

at System.Net.Mail.SmtpClient.Send(String from, String recipients,
String subject, String body)
at TestWindows.FrmSendSMTPMail.btnSend_Click(Object sender,
EventArgs e)
Weird stuff...
My remote server has Windows Server 2003.
So, am I missing something?
Sounds to me like a connectivity problem... How can I check that?
Thanks in advance,
Danny

I'd guess that your ISP rejects connections from IP addresses that do not belong to them.

You may be able to authenticate to your isp's smtp server by passing it your user credentials.
Alteratively, consider using the windows server SMTP service.

Hi
I am trying to create a Richtextbox that able to be able to copy and paste from Word document. The method to paste from word document I have used is Paste(); However there is a problem when in Word document there is table. If the table is located further to the right then when pasted to the richtextbox then the richtextbox will cover a bit of the table.
I have a screen shot here
http://www.mediafire.com/imageview.php?quickkey=3xdzy9xnjmj&thumb=4
Can you please tell me is that the right method to use to paste the table from Word file into richtextbox? Is there any way that I can fix that please?
Thank you very much. I really do appreciate your help.
Best regards

Hi!
The regular RichTextBox cannot display everything you can have in a Word document and some features can be transferred but will not be shown exactly the way they appear in Word.
Tables are among these features.
You can come a little closer to Word if you use a more recent version of the Rich Edit Control than the one the regular RTB uses (V2.0).
This can be done by overriding CreateParams in a class deriving from RichTextBox like this:
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
private static extern IntPtr LoadLibrary(string lpFileName);
protected override CreateParams CreateParams
{
get
{
CreateParams par = base.CreateParams;
if (LoadLibrary("msftedit.dll") != IntPtr.Zero)
{
par.ClassName = "RICHEDIT50W";
}
return par;
}
But unfortunately you'll never achieve a 100% match...

mav

</ItemTemplate>
This code is used to open a popup window when user click this link.
But I get error at: '<%# "javascript:void(window.open('..SubPages/MusicDetail.aspx?item_id=DataBinder.Eval(Container.DataItem,("id_BaiHat"))&type=type'
I don't know how to fix it.help me please !
Thanks advace.

You should place the literal javascript code outside of the databinding expression block. Only your call to DataBinder.Eval should be placed within this block.

Can you give me your code exactly ?
nothing

I've already told you what to do. Only your call to DataBinder.Eval needs to be placed inside the <%# %> block. Your literal Javascript code should be placed outside of this block, the same as your anchor tag.

I rewrite my code and it like below:
<a href="javascript:void(window.open('../SubPages/MusicDetail.aspx?item_id=<%#DataBinder.Eval(Container.DataItem,("id_BaiHat"))%>&type=type','toolbar=no,status=no,menubar=no,scrollbars=no,resizable=no,copyhistory=no,width=450,height=250'))"><%#DataBinder.Eval(Container.DataItem, "TenBaiHat") %></a>
There is no error any more.But it can open new window when I click this link.Nothing happened after clicking this link.
nothing

Have you viewed the source for your page output? Look at how the anchor tag has been constructed and see if there are any obvious problems with the HTML code.

Hi,
I have two Xml document. Both the documents has same root node and also same 12 parent nodes.
Now i need to merge the second document with the first document with the following three conditions,
1) If the child node of a parent node in second doc is not available in child nodes of corresponding parent node in first doc, then append the child nodes with all its child node(Sub childs) to the parent node of first doc.
2)If the child node of a parent node in second doc is available in child nodes of corresponding parent node in first doc,
but the sub childs are different then append the sub childs to the corresponding child node of the first doc.
3)If the child node of a parent node in second doc is available in child nodes of corresponding parent node in first doc, and the sub childs are exactly same then nothing has to be done.
Can anyone help me out.
The xml file is not too large and the order is not under consideration.
Thanks,
Srikanth

public static bool CreateNewWebsite(WebSiteInfo WebsiteInformation)
{
string strIISPath = WebSiteInfo.IIS + WebsiteInformation.ServerName + WebSiteInfo.WEBSERVICE;
// Check if path points to any existing directory
if (DirectoryEntry.Exists(strIISPath))
{
///and here comes exception
--
The system cannot find the path specified.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
