AFAIK, System.IO is in either the mscorlib or the system Assembly, so it's already added in for you. Just type imports System.IO to use it.

Heres what I want :
1. Find a window based on its title from among the windows open at that
time. (or just get a handle to the active window)
2. Once I locate that window, find a button with certain text in it and
then click that button.
3. It wil be awesome if I can also do the same for certain menus.
The biggest problems : I dont know VB or VC++. If someone has a code snippet to take care of such a problem , please let me know. Which is better for this kind of a problem .. VB or VC++?
Thanks a lot.

I got hold of Crystal Reports Developer 8.5. I created a couple of reports with the program. After including them in a project in Visual Basic .NET and trying to open it, I get the following error: "Crystal Dictionary not supported in this version".
Question: Can I import something in VB.NET to recognize the newer version of Crystal Reports?

I'm working on active scripting (vb-script) support in my application, so my application must support some COM objects. I familliar with COM but relatively new to dispatch interfaces and vb-script. Hence, I'm wondering whether I should expose an interface of a child/sub object via a propery or via a method.
Is there a criteria for using properties / methods?
So for example, should I do this:
Dim module<br />
Set module = modules.module("<name>")
or this:
Dim module<br />
Set module = modules.GetModule("<name>")

in COM ,, a property is actually a pair of functions
I think you should properties. they make sense..

there maybe a thread asking how to use Sleep method in .Net.
I know how to declare and use Sleep in VB 6.0, but I don't know how to use it in VB.Net
I create a project in VB 6.0 and convert it back to VB.Net and copy and paste the converted code into my VB.Net project but .. I still get error..
Do I need any special header file to import to use Sleep()?
thanks

Just use System.Threading.Thread.Sleep().

Thank you I though it only for thread.. not same as Sleep()
|
|
|

The Sleep() API does the exact same thing - in fact, System.Threading.Thread.Sleep() just calls the Sleep() API.

I have been trying to uncover a supported way to view pdf files within my windows form in VB.NET, and I am having no luck. Adobe has an unsupported pdf viewer ocx control which is buggy, and all the other controls I"ve seen are way too expensive to be worth it (my other option is to create a hyperlink and pop up the pdf in Adobe viewer as a modal form). Any ideas out there/cheap viewer controls?

Click Project, Components... and add "Microsoft Common Dialog Control 6.0". Add one of these to your form, and it ready to be used. Look here[^] for more info.

I am making a VB project for a class I am taking. It involves using databases in Access. My primary key is called "CustID" I am making a project for a company that sells sports cards on online auctions. My first form is a Customer information page. What I need to do is add the "CustID" number that is loaded and have it transfer onto the Order Information page. My instructor mentioned referencing the form, but I wasnt quite sure what he meant. PLEASE HELP ASAP  Thanks much

If you have two forms, FA and FB, then you can directly reference FB from FA and Vice versa.
I would suggest implementing method like UpdateCustID(ByVal NewCustID) on FB, which can then be called from FA:
<br />
load FB<br />
<br />
FB.UpdateCustID(NewCustIDFromThisForm)<br />
<br />
FB.Show<br />
<br />
Unload Me<br />
Note that it's not necessary to load FB first - if you reference a form, then it gets loaded implicitly anyway, but I always tend to do so, since makes the code a little clearer

A common scenario is using controls made in VC++ and incorporated and nested
into a composite control in VB...
For example
FooActiveX-->VB Composite UserControl-->WrapperVB Control--->WindowsForm
In the past, I've read the recommendation is to bubble up events received by
FooActiveX --> WindowsForm.
But have found in practice, that this can be a maintenance nightmare come true.
For example you would have to raise events up in each one in the chain...
FooActiveX--(raise event)-->VB Composite UserControl--(raise event)-->WrapperVB Control---(raise event)-->WindowsForm
and worse is the reverse, when you have to communicate back downward by
calling and bubbling method calls downward
WindowsForm---(DoFooRefresh)-->WrapperVB Control--(DoFooRefresh)-->VB Composite UserControl-- (DoFooRefresh)-->FooActiveX
Is there a sane way to have your cake and eat it too? That is, to maintain
some kind of OO paradigm by making / using nicely encapsulated composite
ActiveX controls of this nature, without this messy chain messaging going
on?
ie....BROADCAST event, where only WindowsForm....will listen in and care
about event and the reverse, BROADCAST a message/command down
so ideally we would end up with these two instead
FooActiveX--(BROADCAST event)-->WindowsForm
WindowsForm---(BROADCAST command DoFooRefresh)-->FooActiveX

What property controls the initial visible default state of a datagrid?
My application fills a datagrid during form load from a oledb database query.
When the form is loaded the datagrid is blank except for a cell with a + sign
Once the + is clicked then a second cell is shown containing a link. After the link
is clicked the grid then is filled with the data.
How can I programmatically complete the first two clicks so that when the form is loaded
the user sees a full grid of data instead of having to click on the + and then on the link.
Thanks so much

Hi There
What does your code look like, if I use the following the grid immediately shows all the data
(I think it may be from using a DataTable or not?)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim oDA As SqlClient.SqlDataAdapter
Dim oCon As SqlClient.SqlConnection = New SqlClient.SqlConnection
Dim oTBL As DataTable = New DataTable
oCon.ConnectionString = "Initial Catalog = Northwind;Data Source = (local);uid = sa;pwd=;"
Try
oCon.Open()
Catch ex As Exception
MessageBox.Show(ex.ToString)
End Try
oDA = New SqlClient.SqlDataAdapter("Select * from Customers", "Initial Catalog = Northwind;Data Source = (local);uid = sa;pwd=;")
oDA.Fill(oTBL)
Me.DataGrid1.DataSource = oTBL
End Sub

Hello
I was able to show (load and show) a form , from inside a picturebox or frame in VB6.
I mean that, I could show a form named F2, inside a frame named fr which was placed on the form named F1.
There is a form named F1, there is a control (frame) placed on the form F1.
And I was able to show the F2 form inside the frame.
How can I do that in VB.NET ?
Thanks...
Best Regards

I have a program on an XP box on a local network. I want to create a shortcut to that program on another machine. I can create the shortcut, but when the program starts, it brings up a debug screen and gives me a massage that says 'Invalid URL'. The debug window shows a NULL URL. I don't know why a URL is being requested, or how to prevent that from happening. I have a second program that I can successfully invoke from the second machine. One difference between the two programs is that the one that does not work references a dll that is part of the vb.net solution.
Any clues would be appreciated.

How are you sharing the file? Have you put it in a shared directory?
Are the other boxes set up with user accounts on the XP box?
What path do you have in the shortcuts properties?
Can you see the file on the network?
Have you tried registering the DLL on the problem box?
Regards
