If you use javascript you can do stuff like self.opener.forms... to set fields on the form who opened the child form. It can get kind of complicated if you go that way, but it does work.
Here is some old code I used when a child form was allowing the user to select a date: (it is in vb.net 1.1, sorry if that is the wrong version and code language)
Private Sub closewindow(ByVal indate As Date)
Dim myScript As New StringBuilder
With myScript
.Append("<script>")
.Append(Environment.NewLine)
'This code sets the correct field on the opener form
Dim tmpstr As String = "self.opener.document.forms[0]." + CStr(Session("DatelookupField"))
.Append(tmpstr)
.Append(".value = """)
.Append(indate.ToShortDateString)
.Append("""")
.Append(Environment.NewLine)
'focus the opener form
.Append("self.opener.focus()")
.Append(Environment.NewLine)
'Close the calendar window
.Append("self.close()")
.Append(Environment.NewLine)
.Append("</script>")
Page.RegisterStartupScript("close window", .ToString())
End With
End Sub
In the parent form when the button was clicked to open the new child form I set the session variable:
Session("DatelookupField") = "txtBoxWeekending"
Maybe not the best code, I did write it quite a few years ago, but it does work.

I'm having a problem with textboxes not displaying as specified on Pocket PC devices.
Regardless of the specified Width, all Textboxes display as the same size.
<pre>
<asp:TextBox id="txtIntials" tabIndex="5" runat="server" Width="48px" Height="24px" Font-Bold="True"></asp:TextBox>
<asp:TextBox id="txtPedigree" runat="server" Font-Size="X-Small" Width="320px" Enabled="False"></asp:TextBox><BR>
</pre>
Is this expected behavior?
Thanks

There is a formula which multiply each dot value of IP and then adds it up, This value is compaired with lookup data to find out the country name. Don't know if city is also possible? Search it in google or live.com you will find the result.

How to upload file in asp.net 2.0 to server hard disk from client side and down load file
|
|
|
|
|
Drag nd Drop Html control input(file) nd in code behind write following code
string fn = System.IO.Path.GetFileName(YourfileName.PostedFile.FileName);
string SaveLocation = Server.MapPath("FolderName") + "\\" + fn;
YourfileName.PostedFile.SaveAs(SaveLocation);
Response.Write(fn + " Has been uploaded to " + SaveLocation);
Instead of "YourfileName" use de id of input(file) control nd FolderName is de name of de folder on server in which to upload de file.
i think it will solve ur problem.
|

|

You can use the file upload component use the and use the .SaveAs(filename) method to save at the server side.
Thanks,

in saving data in my module, instead of using connection wizard, i use this sql codes:
Dim str As String<br />
dbconnect = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Rara's project\grading.mdb")<br />
dbconnect.Open()<br />
str = "select count(*) from students where studname = '" & txtname.Text & "'"<br />
dbcommand = New OleDbCommand(str, dbconnect)<br />
If dbcommand.ExecuteScalar <> 0 Then<br />
MessageBox.Show("Already exists.", "Result")<br />
cleartxt()<br />
Else<br />
str = "Insert into students(studname, year, course) values ('" & txtname.Text & "', " & "'" & cmbyear.Text & "', " & "'" & cmbcourse.Text & "')"<br />
dbcommand = New OleDbCommand(str, dbconnect)<br />
dbcommand.ExecuteNonQuery()<br />
MessageBox.Show("Record Added.", "Result")<br />
dbconnect.Close()<br />
cleartxt()<br />
End If
but i have an error in the part there -"dbcommand.ExecuteNonQuery()"
a dialog box appear and it says:
An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in system.data.dll
i guess the error there is the combobox that i used? because when i try to erase the "cmbcourse.text" and "cmbyear.text", it runs..but when i put it, there's an error....
how can i fix it???
please, help me!!!

Is the year filed in your database a text field, or a nyumeric one? If the latter, you need to remove the apostrophes around it in your sql statement.
If any of your courses have apostrophes in them, this too will break the code - use the replace function to replace all occurrences of apostrophes with double-apostrophes.

all my database field are text....
the apostrophes that are you saying are in my codes? So i need to remove it?
This is my code before:
str = "Insert into students(studname, year, course) values ('" & txtname.Text & "', " & "'" & txtyear.Text & "', " & "'" & txtcourse.Text & "')"
how can i remove it?
Like this?
str = "Insert into students(studname, year, course) values ('" & txtname.Text & "', " & " " & txtyear.Text & ", " & " " & txtcourse.Text & ")"
but when i do it, it is still dont running?
Can u please write the codes for that, so i can know which one is to be removed?

No - your original SQL statement is correct in as far as it goes, but will crash if any of your text inputs include apostrophes. Because SQL uses apostrophes to mark the start and end of text fields, another one occuring within a field causes problems.
To get round this, SQL accepts two consecutive apostrophes as marking not the end of the text field but an apostrophy within it - thus if your txtcourse.text = "smith's" the SQL statemt would fail, "smith''s" would be accepted.
To take acount for this in all cases, simply use the replace method to replace all apostrpohes within text fields with double apostrophes - thus:
str = "Insert into students (studname, year, course) values ('" & txtname.Text.Replace("'", "''") & "', '" & txtyear.Text.Replace("'", "''") & "', '" & txtcourse.Text & "')"

> I've to run mp3 or .rm songs in my web page
1997 called, they want their HTML back. 
I vaguely remember something about the embed tag. You might have to look at that if there isn't anything that ASP.NET itself provides for this purpose,

i have a checkboxlistitem.where let say A,B,C,D,E are the items in that control.
and below that 5textboxes are there named as textbox1,textbox2......textbox5.
initiallay all textboxes are disabled.now i want when ever i select A the corresponding checkbox should be enable i.e textbox2.
and likewise if i select B then textbox2, if Dthen textbox 4.likewise.
what will be the vb.net code for it.
|
|
|
|
|
you need to write code inside
protected void CheckBoxListmst_SelectedIndexChanged(object sender, EventArgs e)
{
if(checkbox1.selectedvalue == 'A')
{
textboxA.enabled = true
}
}
something like this.
hope this will resolve your issue.

hello frndz. thanks for ur reply n solution to my query.
here another small query for you.
i have a checkboxlistitem.where let say A,B,C,D,E are the items in that control.
i am able to store the mulitiple value of the checkbxlist item .(by taking a string and storing the multiple value by "," operator).
now my problem is that when i am retriving the value from the db ,am not able to retrive the value of the lsitboxitems.
(suppose in emp_id "1" i have stored the values of A,C,D from checkboxlist,when i retrive the record having emp id1. i want to retrive its value i.e A,C,D and the corresponding checkbox of the values to be checked in the front end.)
what will be code in vb.net
|
|
|
|
|
first u can splite the result row with 'A,C,D' with ",". now u have the array of the all checkbox which need to select. now with checkboxlist you can find the ur checkbox by text or value and give the property selected

can u write the code for it. actully i have tried this logic but may be with wrong code. so asking you to write the code for it in vb.net
|
|
|
|
|
For Each dr As DataRow In checkboxlist.Items
if dr(columnname) = 'A' then
checkboxlist.Items.checked = true
end if
Next

Here is the code you asked for...
Dim lstItem As New ListItem
Dim lstItems() As String = Value.Split(",") 'Value = "A,B,C"
For Each lstItem In chklstItem.Items
For I As Int16 = 0 To lstItems.Length - 1
If lstItems(I) = lstItem.Value Then
lstItem.Selected = True
End If
Next
Next
I suggest you to write a property procedure which will GET and SET the values of the CheckBoxList...
Regards
John
