I am using the viaul basic 2008 express edition. I dragged and dropped reportviewer control on a Form and created dataset.xsd by dragging the table in to .xsd.
Now when i click 'Design a new report' link on the type right corner in the reportviewer control on the form, nothing happens at all.
can someone help on this how to work on this reportviewer control? i have some examples on this, but got stuck at this point of "Design a new report".

Don't worry about it. Just put the below codes to your button click()
Dim ObjRpt As New CrystalReport1
ObjRpt.SetDataSource(DS62.Tables(0))
CrystalReportViewer1.ReportSource = ObjRpt
CrystalReportViewer1.Refresh()
CrystalReportViewer1.Visible = True
From the above, Ds62 is Dataset and used to fill the datas, and it has send to the report.

I tried Your code, but showing error that "Type 'CrystalReport1' is not defined".
One more thing, does Visual Studio 2005 professional edition supports Crystal report?

Hi all,
Is there any way or solutions which allows a program to get/retrieve all the ip addresses currently active which belongs to the same network(same subnet)? For example, I run this program in one of the workstations within a network and i will get all the other workstations' ip addresses.
Regards and many thanks!

If you know the range of valid IP addresses, have you considered just interating through them and pinging them in turn? The currently active ones will hopefully reply. Limitations with this would include that firewalls can sometimes block pings, and if the subnet is large, it could take a while, but it might be alright for your specific network.
|

The only way to do that would be to start pinging every IP address in the subnet. The response you get will tell you in there is TCP/IP stack that responds, but that also depends on firewalls blocking the ICMP packets, so you're results may be skewed.
Bascially, there is now way to reliably find every active IP address on a subnet.

Thanks to all!. Was hoping to see if there's any other faster or better way in doing it due to the limitations, anyway great thanks!

hi everyone,
I have a tab control with 3 tabs, A,B,C.
I have one one database "student" in which i have 4 columns.
There are two datagridviewB and datagridviewC in the two tabs B and C.
I am updating the entries of a datagridviewB by entering details in a form present in Tab A.
Now when I am working in tab C to update the datagridviewC, say for example filtering "student" database and displaying filtered results in datagridviewC; while updating datagridviewC, I noticed that datagridviewB in tab B also getting updated.
My code for filter "student" database in tab C is like this:
cmd = New SqlCommand("SELECT * FROM student WHERE [Name] <= '" + name + "'", con)
myDA = New SqlDataAdapter(cmd)
myDataSet = New DataSet()
myDA.Fill(myDataSet, "student")
datagridviewC.DataSource = myDataSet.Tables("student").DefaultView
Can someone tell me, how to update the datagridviewC in tab C without altering the entries present in datagridviewB in tab B?
FYI : my datagridviewB contains all the student data and in tab C i am filtering the database based on "Name" and displaying in datagridviewC.

I'd guess that they both have the same datasource. Make a copy of hte data source to bind to form C

So you get the same answer today as you got yesterday but from a different person.
Give each DGV its own datatable, not a copy, not a dataview filtered differently.
OR
Create a BindingSource for each DGV.

*sigh* how utterly frustrating. CP needs a popup that shows recent questions from the same poster.

Thnaks Holmes. i am very new to this. Anyways, I dragged and added a "BindingSource" into my form and added a code like this:
cmd = New SqlCommand("SELECT * FROM client_details", con)
If con.State = ConnectionState.Closed Then con.Open()
myDA = New SqlDataAdapter(cmd)
myDataSet = New DataSet()
myDA.Fill(myDataSet, "client_details")
DataGridView1.DataSource = myDataSet.Tables("client_details").DefaultView
Can You please tell me how to add the bindingsource to this DatagridView1?
As you told , I have to create a BindingSource for each Datagridview; so if You can tell me how to bind this, then i can carry out my work for other datagridviews in my project.
thanks.

Set the DataSource property for each DataGridView to the corresponding BindingSource

You need to inject a BindingSource between the DataTable and the DataGridView
oBSClient = new BindingSource
oBSClient .DataSource = myDataSet.Tables("client_details").DefaultView
DataGridView1.DataSource = oBSClient
Then if you are using the same table you can create another BindingSource based on myDataSet.Tables("client_details") and bind that to the second DGV

It is throwing error as "Null object reference".
|
|
|
|
|
So debug through the code and find out which object is not being instantiated. You did remove the space I inadvertantly left in the declareation right!

I have done this :
Dim myDataSet As New DataSet()
Dim newbinding As New BindingSource
newbinding.DataSource = myDataSet.Tables("clinet_details").DefaultView
DataGridView.DataSource = newbinding
while debugging i found following error in the 3rd line above:
"use the "new" keyword to create an object instance".
how to fix this?

Wich line - presumably when assigning the table which is not populated in this code.

There's this dashboard application that we have, written in VB.NET. I have been given an assignment - to make the dashboard viewable from a web browser. I presume this means creating web forms to replace the Windows Forms. I think I'm pretty good with VB.NET, but I don't know the first thing about web forms. I know some very basic HTML, and I've dabbled with Tomcat & JSP, but I'm not even sure where to start reading up in order to learn what I need to accomplish the task at hand.
Can anyone point me in the right direction?

Buy a book on ASP.NET. Seriously, you've not going to get the background you need from a couple of forum posts and some badly written tutorials on the web.

why do Code project MVPs answers only easy questions or only refers books
|

You my friend are going to go far, but not as a developer, asking for a crash course in web development and then bitching that 2 MVPs point you at a book is really not the way to go.
People spend years studying and working on web development and you want it in a forum post, you even asked for a "course", what do you think a course is, idiot.
