I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
In trying to test some graphic features, I am trying to get them to display on load so button doesn't have to be pressed. I used the following code as suggested from forum. Message boxes run but ellipses aren't displayed until button is clicked which is what I am trying to avoid!

Button1.PerformClick()
Button1_Click(Nothing, Nothing)

i have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.

I have a datagridview with several combobox columns.I've filled these with data from a database.But the combobox standard displays as empty. You have to click/select it and choose the right value.But what I want is that the first value is displayed and selected automatically. With a normal combobox you can do this by setting the selectedindex to 0.However this seems not to be possible with a datagridview combobox.Is there a way to display the first value anyway?

View 1 RepliesI have a datatable similar in structure the first attached image where each * represents some data
Ultimately I want a new table in the form of the second attached image.
Currently, I have opened a connection to my access database and pulled in the data for case 102 into a datatable and case 103 into a separate datatable. [code]...
Then I loop through each row in Dt1 to check if item1 in Dt1 exists in Dt2. If it exists, I determine which row it's at and add in the data for item2 and item3 into Dt2.
How do i only display a messagebox only once, since if it were to be displayed every time it would be annoying.

I want to display a date in a textbox after 25/02/2009
I Used a sql query for getting a next date
Select CONVERT(CHAR(10), DATEADD(dd, 1, MAX(SDate)), 103) AS SDate from tb_Sched_Add
the above query is displaying a next date 26/02/2009 in the textbox, but it is taking a some second to display. There is any way in program itself getting a last value of the row (date) in datagridview and display the next date.
