I won't send you the code, but here are some tips

Always use plaintext passwords. Hashing takes too long
Make the username case-sensitive. People love that
Color the login form yellow, green and purple. No-one will hack it if you do that
Wouldn't it be convenient if the users could have a little dog or paperclip to help them log in?

In my VB code
Dim MyNewRow As DataRow
MyNewRow = Me.DataSet1.Tables(0).NewRow()
MyNewRow.Item("reason-code") = "RX6"
MyNewRow.Item("description") = "Hello from VB"
MyNewRow.Item("sl-paid") = True
MyNewRow.Item("sp-paid") = False
Me.DataSet1.absence.Rows.Add(MyNewRow)
Me.AbsenceTableAdapter.Update(Me.DataSet1.absence)

but ony first field "RX7" gets into the data base
any help would be appreciated

First, which version of Visual Studio are you using? Did you create a Typed DataSet using the designer? Also, what does the SQL looks like that you're using in the AbsenseTableAdapter? Does this database table have a PrimaryKey??

VS2005, this is an ODBC connection to a Progress database, and yes the table does have a primary key..on the 'reason-code' field, which looking at the code was the only field in update statement... I deleted all and tried again, but now I can't even get it to to do an update.

So I added an insert query and that worked just fine.

OK, great! But, my only concern is "Reason Code" doesn't sound like a good candidate for a PrimaryKey. It would seem that there could be multiple records in the table with the same reason code. This is not a good situation where the PK has to be able to uniquely identify every record in the table, which is a requirement for the TableAdapter to work.

Well I don't have any control over that.... this is a table in a SYMIX ERP package, and I am working on importing data from a different ERP package into it. (I don't like the limitations of Progress data base, which is cause of this, but no choice, that's what it is written in.)
But My Insert and I added my own update and it all works.

Hi everybody,
I used a background with dark gray regions as transparent regions for my splash screen
On my development computer, it shows transparent regions, but on all other computers it's opaque
I even tried installing Windows XP in VMware on the development computer, and still it didn't work!!! OMG | :OMG:

Any suggestions are welcome...
Thank you

is the developement computer a server? sometimes it can depend on how the themes are setup in XP, i.e. windows classic etc..

Do you have XP styles enabled in the properties of the application, go to properties in visual studio in the application tab look to see if this changes anything?

VB.Net - Close a form

I wonder if anyone can help me solve this problem.

On a form load, I do a simple yes/no test. If I say No, then I want to close the form I am loading. I have tried Unload, me.Close, formname.Close but with no success. Keep getting errors.

Is the problem with the Load event? I have tried closing the form from a procedure I created but no luck.

I am properly doing something really stupid or missing sometning simple out.

It's a bit late to do the decision in that point. Could you modify the opening logic so that you don't open the form at all if your test fails (don't even create it).

I think it's by design.

I want to create a windows service that checks the status of a task in task manager.If it isnt running then restart the application.ie; it is 'Not responding' then restart.

However I dont know how to get the status of the task.Will getprocessbyname() method work for this?

Or is there a better way?

You can use Process.GetProcesses Method[^] to get all processes and then investigate Responding [^]property.

So doesn't it mean that if you've posted, say 30 messages during last 3 days, you have replied just before someone else in 90% of cases and only in 10% someone else has done that. That wouldn't be bad at all. Smile | :)

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
System.Diagnostics.Process.Start("C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv.exe")

End Sub

The Process class has a MainWindowHandle property that you can use to set the Parent window to your hosting control, which should normally be a Panel control. Get the MainWindowHandle property of the Process object you just started, then you can call the Win32 function SetParent[^] to make the application window a child of the Panel window.

WARNING! Not all applications will tolerate this technique! You can run into painting problems with the application that you host!

Also, you cannot force any popup windows that the hosted application shows to show up inside your application.

Well i'm gonna assume here....

i think this is because you may have forgot about the headers in your gridview/datagrid etc..

so you need to do this...

If e.Item.ItemType <> ListItemType.Header Then
    
    Dim tbox As TextBox = CType(e.Item.FindControl("txtQty"), TextBox)

  End if

Hope this helps!
