Hi,
In winforms or wpf application, lets say there is one container control which adds controllers dynamically and it also adds event handlers of that child controls.
Now if I call a clear method of the parent container control, will the event handlers added be removed automatically?
If not and I dont remove them (event handlers), will it create any other issue?
Please suggest!
Thanks,
Divyesh

when you clear a container control, it disposes of all the contained controls; each control will be available for garbage collection, and the event members they contain will have no influence, just like any other data members. There is no need to remove handlers at all.
BTW: The same applies to a modeless form that gets closed.

Hi
Is there a way of installing other software such as MySQL in a setup project. If so is it also possible to execute a script to create a database?
Thanks

In C#2.0,the Codedom library how to generate the method of foreach? 
|
|
|
|

A foreach is actually a convenience wrapper around a loop with an enumerator. That's what you need to enumerate over. Try to create a CodeDOM for this instead:
IEnumerator e = item.GetEnumerator();
while(e.MoveNext())
{
myList.Add(ConvertToObject(item));
}

Guys;
I used system.drawing.Image to get a MetaFile, the type is an EMF file:
Image img= new Metafile(new System.IO.MemoryStream(), HDC,rc, MetafileFrameUnit.Pixel, EmfType.EmfOnly);
After an EMF file is created. I need to convert it to Bitmap, using: img.Save(sTempfilename, ImageFormat.bmp); Its background becomes black. I think i can not save directly since the format is different.
Would you give some suggestions on how to convert the EMF image to a Bitmap? Thanks very much.

You really are a grade A, full blown, moron of the highest order. First of all, this is advertising, so you shouldn't be posting it in the forums - secondly, and this proves you are a wlueless canker, what has this got to do with .NET?

hi dude,
Please read this[^] guideline before you post anything in the thread.
Please do not market your product, Website or yourself in discussion forum. There are other sites which
allows you to do that, this is question answer forum.
You can tell some marketing company they will market your product or site. Like if you can tell google
then google will market according to your way but you need to pay for that.

I am using a stored procedure to insert data into two tables in sql 2008 server. Now while handling exception I am using exception code to check the exception and accordingly i am showing the error message to the user.Can u tell me a better option to do the same.
Public Sub rtrnQry(ByVal usrNm As String, ByVal psWd As String, ByVal fNm As String, _
ByVal lNm As String, ByVal empId As Integer, ByVal proNm As String, ByVal aDm As String, ByVal rowno As Integer)
Try
Using cn As New SqlConnection(sqlConnStr)
cn.Open()
Using cmd As New SqlCommand("InsrtLogin", cn)
With cmd
.CommandType = CommandType.StoredProcedure
.Parameters.AddWithValue("@empid", empId)
.Parameters.AddWithValue("@username", usrNm)
.Parameters.AddWithValue("@password", psWd)
.Parameters.AddWithValue("@firstname", fNm)
.Parameters.AddWithValue("@lastname", lNm)
.Parameters.AddWithValue("@adminpri", aDm)
.Parameters.AddWithValue("@proName", proNm)
.ExecuteNonQuery()
End With
End Using
End Using
Catch ex As SqlException
If chkBox1_Crtusr.Checked Then
If ex.Number.Equals(2627) Then 'Exception code for Primary Key Violation
MsgBox("Duplicate Employee ID cannot be inserted. Violation of Primary Key " & _
"Constraint Occured. Enter an unique value.Please check row number : 1", MsgBoxStyle.Critical, "Error")
Else
MsgBox(ex.ToString)
End If
If ex.Number.Equals(208) Then
MsgBox("Invalid Table Name. Check the Sql String.", MsgBoxStyle.Critical, "Error")
End If
End If
If chkBox2_Crtusr.Checked Then
If ex.Number.Equals(2627) Then 'Exception code for Primary Key Violation
MsgBox("Duplicate Employee ID cannot be inserted. Violation of Primary Key " & _
"Constraint Occured. Enter an unique value.Please check row number : 2", MsgBoxStyle.Critical, "Error")
Else
MsgBox(ex.ToString)
End If
If ex.Number.Equals(208) Then
MsgBox("Invalid Table Name. Check the Sql String.", MsgBoxStyle.Critical, "Error")
End If
Now I am calling the above procedure
Private Sub btnSubmit_CrtMul_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit_CrtMul.Click
Dim cnt As Integer = 0
Try
If chkBox1_Crtusr.Checked Then
rtrnQry(txtUsrNm_1.Text, txtPswd_1.Text, txtFName_1.Text, txtLName_1.Text, txtEmpID_1.Text, cmbProNm1.SelectedItem, cmbAdmin1.SelectedItem, 1)
Dim sqlLogin As String = "Select * from login where user_name ='" & txtUsrNm_1.Text & "'"
Dim usrVerified As String = DataStore.ExecuteScalar(sqlLogin, sqlConnStr)
If usrVerified.Length > 0 Then
Call ClearData(1)
cnt = cnt + 1
End If
End If
If chkBox2_Crtusr.Checked Then
rtrnQry(txtUsrNm_2.Text, txtPswd_2.Text, txtFName_2.Text, txtLName_2.Text, txtEmpID_2.Text, cmbProNm2.SelectedItem, cmbAdmin2.SelectedItem, 2)
Dim sqlLogin As String = "Select * from login where user_name ='" & txtUsrNm_2.Text & "'"
Dim usrVerified As String = DataStore.ExecuteScalar(sqlLogin, sqlConnStr)
If usrVerified.Length > 0 Then
Call ClearData(2)
cnt = cnt + 1
End If
End If
If chkBox3_Crtusr.Checked Then
rtrnQry(txtUsrNm_3.Text, txtPswd_3.Text, txtFName_3.Text, txtLName_3.Text, txtEmpID_3.Text, cmbProNm3.SelectedItem, cmbAdmin3.SelectedItem, 3)
Dim sqlLogin As String = "Select * from login where user_name ='" & txtUsrNm_3.Text & "'"
Dim usrVerified As String = DataStore.ExecuteScalar(sqlLogin, sqlConnStr)
If usrVerified.Length > 0 Then
Call ClearData(3)
cnt = cnt + 1
End If
End If
Now when I am doing this, for each exception the error message is appearing twice, I need to take care of that as well. Please Help, Thanks in advance

Hi,
i am new to vb.net and i am trying to reset all the textbox and combobox in my application as soon as execute query statement gets executed. Actually i have used a series of rows and combox to enter data to the table, if check box one is checked then i am allowing to the enter the data, my form looks somwthing like an excel sheet. I am able to enter data - without any problem, but i am unable to reset the feilds. please some help.

Unfortunately, your question is not very clear.
I would recommend you use a collection like a Dictionary (key and value) to keep track of your object(s).

As already noted, it's not entirely clear what you're trying to do. Post a bit of your code and we might be able to help.
But in the meantime, if I'm reading your post correctly, you want to clear the contents of your controls after you use them. It sounds as if they are all text controls, in which case you can clear them by iterating through all of them and setting the .Text property to "". That seems a bit inefficient to me, and probably unnecessary, but without seeing your code it's hard to say. If all you want to do is set up the controls for the next entry, you can use the Selected property on entering the field to let the user type a new value that replaces the old.
