U can create sub add grid follow sample:
Sub Fill_Grid(Grid_Name As Object, Data_Text As String, X As Integer, Y As Integer, Attrib As String, Location As String)
With Grid_Name
.Row = Y
.Col = X
If UCase(Location) = "L" Then
.CellAlignment = 0
ElseIf UCase(Location) = "C" Then
.CellAlignment = 5
ElseIf UCase(Location) = "R" Then
.CellAlignment = 7
End If
If UCase(Attrib) = "B" Then
.CellFontBold = True
End If
.Text = Data_Text
End With
End Sub
This sub use flexgrid I hop u can modify for datagrid.

I've seen this mentioned before, and I know how to create the app.config file in my project, and I know theoretically how to read from it, but it never works for me. So, I was wondering if someone could give me a simple example of, say, the following:
Create an application (using Visual Basic.Net Home Edition) that will remember the form's Opacity, Backcolor, size and position using a configuration file (app.config).
I figure if I see the code for that, I'll be able to figure out how to use the app.config file to remember other stuff too. I know it can't be that hard, because lots of people seem to use it all of the time.
Thanks for the help.

As you probably know, the app.config file is read by the framework and accessed through the ConfigurationSettings.AppSettings[^] collection. However this is a one-way communication, Reading only. The app.config AFAIK is only designed for external settings to be created for an application, and not for the application to write to.

Herm... that's not good. So, should I just stick with my original idea and write a text file? That's gonna be a pain... anyway, thanks for the help.

Settings are very easy to save in .NET, because you can serialize objects. This makes it almost trivial to create a class to represent your settings, and then use serialization to save and load it to/from disk.
See Serialization, Basic Serialization in the .NET SDK docs.
There are other ways, but that is my favourite.

Hello,
I am trying to save the date to a table from a date picker so that the next time the form is open it will have the last date picked which i will call form the table and assign it to the datepicker as the value. the problem i am having is that when i insert the date into the table which the field is formated to Date i get 12/30/1899 for every date that is inserted. Can someone tell me if there is an easier way to do this or how I Can fix this problem. below is the code i am using.
Thanks,
Santana
'delete old dates and Saves Dates to date table
Dim startdate As Date
Dim enddate As Date
startdate = pkrstartdate.Text
enddate = pkrenddate.Text
datedap.DeleteCommand.CommandText = "Delete * From datetbl"
datedap.DeleteCommand.ExecuteNonQuery()
datedap.InsertCommand.CommandText = "Insert into datetbl (startdate,enddate) values (" & startdate & "," & enddate & ")"
datedap.InsertCommand.ExecuteNonQuery()
MsgBox(startdate)
MsgBox(enddate)

Stringing together an SQL statement like this is a bad idea. Instead, use a stored procedure that can validate what your putting into the table. This will also give you the ability to use SQLParameter objects that can properly convert the date to an SQL compatible DBDate and back again.

You're going to have to supply MUCH more information that this. What does your class look like? What code are you using to create an object form the class and populate it? How are you trying to save the information from the TextBox to the object? We need to see some code samples...

Your making a new instance of an frmAdd form here. You then expand an array and add a new (blank) CD object to it. Then, your populating the textbox controls on the form with the information from the newly created CD object, with is all blanks. You then check a checkbox control on the form, which is never displayed by the way, and then increase the counter.
All the assignments to made are moving data (blank data) TO the form, but never FROM the form to the storage class you made!

i reversed the statment to say
.artist = add.txtartist.text and i still get no data?
|
|

That's because everything you created in this sub is brand spanking new! Your not using the data from the EXISTING form at all, you're using it from a form that you create in this sub, but NEVER display. So yes, you're adding a bunch of blank information to your new CD object.
Use the EXISTING Add form you have already displayed (at least I think you did) instead of creating a new one in your sub.

Hello, I´m programming a Security module for an application. To check out piracy i've been asked to verify the hard drive serial number and the BIOS serial number. I finally found a way to get hd's, but still haven't found a way to BIOS.
Can anyone help me?
Thank you anyway.

Easy enough to get the drive's serial number through WMI. Win32_LogicalDisk has the VolumeSerialNumber attribute.
The BIOS on the other hand isn't so easy. It's in the WMI Win32_BIOS class, but, not every BIOS HAS a serial number. My serial number on my Phoenix BIOS'd machine is "xxxxxxxxxxx". You'd be better off using various parts of the Win32_BIOS class and other pieces of information from other classes to generate your own serial number.

Hi all,
I have a webservice (asmx) and i want to make a reference in a client project.
The problem is that i only see my datasets. We're only talking about design (not runtime environment).
example:
The webservice is called X and contains:
a dataset called ds
a function called GetDs()
The reference in the client-project is called R.
R.ds -> he finds it perfectly.
R.GetDs() -> doesn't show up in the list and gives an error when I want to use it (design time)
There's something more odd in it. R contains something called X ?!
When I call the server (asmx) I see the methods and all and they work perfectly fine.
Is there something I forgot when I builded the webservice or is there something wrong in the reference?
Your help would be greatly appreciated,
Christophe
