Office uses all sorts of custom controls, you may have to write your own.

I am working on a macro app. I need to know how to show the desktop from my application. I already have functions from the user32 and kernel32 that will do things like minimize windows, close windows, ect. Is there a function inside a windows dll that will show the desktop, or is there another way to do it? I have already tried to do something simple like
Shell("Show Desktop.scf")
And that failed miserably.

The desktop is shown by minimising all the windows, enumerating and minimising seems the best way to me.

Maybe something like this[^] would do the trick...?

This is C# code but it should be easy to convert.
Shell32.ShellClass shell = new Shell32.ShellClass();
((Shell32.IShellDispatch4) shell).ToggleDesktop();
System.Threading.Thread.Sleep(5000);
((Shell32.IShellDispatch4) shell).ToggleDesktop(); You'll need to add a reference to shell32.dll which is in the System32 folder in XP.

Hello, I am beginner vb.net programmer from Greece. I would appriciate if someone could help where to search to find how can i draw on an immage on a form. For example to draw dots or simple lines on a specific image on a picture that is placed on a picture box and then save it in a database as an image. The only thing that i know is the database part.
Thx a lot for your time

You use the paint event to draw on your form, draw the bitmap first then draw on it. The Graphics object is what you need to research.

hi Amit Battan Ror
Have you initiated a Development in vb6?
If so,VB6 its Dead incase you dont know. Try to learn C# or vb.net.If your Company is Still Planning to keep vb6 apps and you have to maintain them, start sending out your resume because you are going to kill your skills. Now lets get back to your error.To update a Database record.. the Server has to know exactly which record it is that you want to change.. ie. it needs a UNIQUE key of some kind to process the record. IF in your DataBase table you do NOT define a field as being unique, ADO will look at the data and then try to build a (temporary)UNIQUE key.. which then can be used to perform the update. Sometimes ADO
is successful in doing this.. and sometimes it is NOT (as witnessed by your present dilemna).The first thing you should do is go and check the Tables you are using to make sure that each of them has at least ONE unique field defined.. and if there is none.. add a Unique identifyling field (such as an Autonumber) to it.
Hope it helps

Hello Everybody
I have 3 form on my project
1. frmNewOrder (have a button called btnPayment also have orderID)
2. frmExistingOrder (have a button called btnPayment also have orderID)
3. frmPayment
when you click btnPayment from frmNewOrder or frmExistingOrder then how can I send orderID value to frmPayment
I have done something
Public Shared OrderID As Integer (on frmNewOrder)
I put code on frmOrder page load events
orderID = frmNewOrder.OrderID
I know its really a wrong concept.
Any idea or example will be really helpful
Thanks in Advance

how are you creating a new instance of frmPayment? in the click event of btnPayment correct? Pass the value into frmPayment after creating the instance.
dim frmPay as new frmPayment
frmPay.OrderID = me.OrderID
frmPay.showdialog

Hi,
If frmPayment isn't equal to nothing then you can set a variable in frmPayment through a public property.
e.g.
in frmPayment:
dim intOrderId as integer
Public WriteOnly Property OrderID() as Integer
Set(byval value as Integer)
intOrderId = value
End Set
end property
and in frmNewOrder:
frmMyPayment.OrderID = orderID
However, if frmPayment is not yet initialised, you can call the new constructor passing the orderid as a parameter.
e.g.
in frmPayments:
public sub new(byval orderID as integer)
me.intOrderID = orderID
end sub
and in and in frmNewOrder:
Dim frmMyPayment as new frmPayment(orderid)
Is this OK?

Can some body help in reading the EDI files using VB.net or C#
|
|
|
|
|
Your question is pretty much unanswerable considering you haven't said anything about what your doing with the file. Reading an EDI file is just like any other text file. Parsing it and getting data out is another story. You may want to make your life a bit easier by Googling for "edi tools for programmers".
|
|
|
|
|
Thank your for the suggestion. We are having a Practice Management product in which we generate EDI 837 and parse 835, 276, 277 and etc and take the data out. The current system is very slow(i.e. for parsing 835 file which has 3000 transactions takes about 3hrs). we have designed the product using VB & SQL Server. So I am looking for the better approach.

If it's going that slow, you've got some serious design issues in your app. You're going to have to find out what part(s) of your code is taking so long to execute, then look at methods of speeding those sections up. This is probably going to require you redesigning your application. There's three glaring possibilities.
The parser may be slow. The easiest thing to do is to use a third-party library designed specifically to parse the files and return the data to you.
There may be a data processing problem. What are you doing with the data once you get it out of the parser?
Your SQL code may be inefficient. You may be doing a bunch of sutff using SQL in your VB.NET code instead of using stored procedures or some other more efficient use of the SQL processing power.

Hi,
I am binding a data in a detail view at run time. But I also want to edit it at the run time. I have tried the following code.
Protected Sub Detailsview1_ItemUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdateEventArgs) Handles Detailsview1.ItemUpdating
Dim index As Integer = Generic_DG.SelectedIndex
Dim con As New SqlConnection(ConfigurationManager.AppSettings("connectionString"))
Dim cmd As New SqlCommand()
cmd.CommandText = "UPDATE Products SET ProdName=@ProdName where ProdId=@ProdId"
cmd.Connection = con
cmd.Connection.Open()
cmd.ExecuteNonQuery()
cmd.Connection.Close()
End Sub
How can I replace @ProdName with data in a detail view?
OR
Which property of the detailview I have to use for it?

hi
I see what you are trying to do , but your question says something else, now from what i see from your code, you have parameters that are not declared.
