I am working on a Windows Application where I have a button that creates tabs in my Tab Control at run-time. The controls inside of those tabs are obtained from a User Control which I created. I would like to now add functionality to allow a user to close each particular tab with a button inside each tab that gets created at run-time. I am having a hard time figuring out how to access the tab control (located in the main form area) from within the User Control to accomplish this purpose. If anyone has any ideas or suggestions, it would be greatly appreciated!!!

Probably delegates
There ws something similar in one of my earlier projects and Delegates made that possible.

It's not considered polite.

I think d@nish has the right idea. I assume (probably a big mistake  ) you're creating the "close" button from the same level you're creating the tab control, like so:
Form1::someFunction(){
this->Controls->Add(tabControl);
tabControl->Controls->Add(closeButton);
}
Maybe not in the constructor necessarily, but you get the idea. Anyway, I set the closeButton's click handler to a function in Form1 in this case, that would somehow close your tab (as for the actual close operation, I'm not sure how to do that, I haven't done much with tab controls).

I am connecting to a printer and when it's offline, it takes about 20 seconds before the exception. The printer is called from a timer that fires every 20 seconds. Is there a way to make the faster, or to check the status and get an immediate response, like in 1 or 2 seconds?
Code:
Public Shared Function SendStringTCP(ByVal Hostname As String, ByVal Port As Integer, ByVal StringToSend As String)
Dim bSend() As Byte = Encoding.ASCII.GetBytes(StringToSend)
Dim MyTCP As New TcpClient 'create a TCP client
Dim MyStreamTCP As NetworkStream
Try
MyTCP.Connect(Hostname, Port)
MyStreamTCP = MyTCP.GetStream
If MyStreamTCP.CanWrite Then
MyStreamTCP.Write(bSend, 0, bSend.Length)
End If
MyTCP.Close()
Return True
Catch ex As Exception
MyTCP.Close()
Return False
End Try
End Function

Hi all,
I have an .exe which is working fine. Now I have to make a schedular programatically which will invoke the .exe(console app) every day at 6.00PM and performs the operation and then quit after completing the job.
Kindly help me in doing that....
Thanks

Hello !
You can use a timer or a thread in your C# application testing current time. When current time is 6.00 you call Process.Start method
see
http://msdn.microsoft.com/en-us/library/system.diagnostics.process.start.aspx
I think that the best way is to use windows task scheduler.

I dont understand this some time.
His last post is still on the first page of Windows Forms Forum, he made a new post asking same question.
By the way, here is the link(though its just 3 messages below) 
http://www.codeproject.com/script/Forums/View.aspx?fid=387161&msg=2674203[^]

If he would have spent half of this time(posting 3 posts) in Google, I bet he would have got the right solution on the very first page it self.

Most of the times I see that people don't even read all the responses to their posts.
This is nothing but negligence.

Simplest approach would be to use the Windows Task Scheduler.

Hi All,
Iam using WMI to get the required printer job information.Here Iam using "Select * from win32_Printjob" from ManagementObjectQuery. In this Iam using thread.sleep for 10 seconds to get the pages,size.
Without thread.sleep Iam getting pages, size as 0.
But this sleep for 10 sec mechanism works only for small documents.
When I get large document It is unable to get the no.of pages,size(just showing them as 0).
1.Is there any way to get the correct pages,size of print document?
2.Is there any way to know that a document came for printing is totally read by spooler?
3.I think after reading all the data only it will go for printing.,am I right or wrong?If right,then how to know that status ready for printing?
Kindly help me
Thanks

Hello,
Can anybody point me to some information on creating a databound control like the DataGridViewComboBoxColumn? I've been trying to format the DataGridViewLinkColumn like the ComboBoxColumn where the cell is linked to a seperate table that is referenced by cell's ID value. The reason for doing this is because I want a friendly text displayed instead of the unpleasent id value showing. The problem is that the DGVLinkCell does not behave like an html link where you can store the url and the text seperately.
Any help would be greatly appreciated,
Richard

Hi,
Inherit from the DataGridViewComboBoxColumn, add necessary information to private fields (for example reference to dataset holding values, selected key value and so on), use tag property to link user selected text to the actual object or row.
Hope this helps,
Mika

I can't really use that option because I'm not wanting the UI of a combobox. If I knew how the combobox implemented the DataSource property, it would help.

Oh I see, sorry about the misunderstanding. One place to start is to take a look at ComplexBindingPropertiesAttribute Class[^] Also there are lots of articles in MSDN concerning data binding.
If you want to take a look at ComboBox implementation, you can use Reflector[^]
Hope this helps,
Mika

Great info. I have reflector but never tried to decompile MS code.

How to insert multiple records into a database table that are entered into a datagridview. With a single shot of Save all the records in the datagridview should be updated using C# . Can any one help me in this regard.
Please tell me the solution as i have wasted near about whole day on this. I did not find help in google search.
Any help appreciated

What did you search for in google? Try this[^]. Or try searching CodeProject articles. The second item in the google search was this CP article[^].
Hope this helps.

Presumably your datagirdview has a datasource, hopefully a table, when you create a new row in the DGV this creates a new row in the underlying datatable with a rowstate of ADDED.
When the user saves loop through each row testing the rowstate and deal with the added/modified rows
Never underestimate the power of human stupidity
