I have written a small app in vb.net (Using VS2005 Beta) that performs some screen scrape operations. The website that I am scraping has a structure like website.com/Page.asp?id=xxxxx
The id's are numeric and so my app loops thru one at a time incrementing the ids.
My internet setup is Cable modem with a Netgear router. About every 20 minutes while this app is running, my router loses connection with the modem causing me to have to unplug and replug in the router. A few seconds later everything resumes normally. I have never experienced this problem with my router and only behaves like this when this app is running. Have you ever seen something like this? Any ideas on the cause?

If you're scraping this site, then it's probably God punishing you.

Lol, perhaps. Well, in my defense, Im only scraping for personal consumption.

Makes no difference to the effect you have on the bandwidth of the sites you scrape.

I have a small program to send emails thru visualbasic 6.0. I am using vbSendMail component. When i tested my program in the localnetwork its working fine. But when i run the same exe in Internet there was no error, but the mail was not sent. I think it the problem with the SMTP server. I have downloaded QK SMTP Server and installed in my system. Now when i run my program in the internet its working ( i have give the SMTP server name as 127.0.0.1). Now i want to run my program in the internet without using any other SMTP Server. How could i do this.. I am always connected to internet and i have my own webspace. How could i use my webservers SMTP address/ip and run my program.
Thanks in advance,

In your code you could try putting in a reference to your local SMTP Server such as:
SmtpMail.SmtpServer="localhost"
I have similar where my code is in a submit button and fields in a form are filed and sent and when I click button this code is called:
Mailmessage mail = new MailMessage()
mail.To="e_screwz@company.com"
mail.From="user@usercompany.com"
mail.Subject=""
mail.Body=""
SmtpMailServer="localhost"
SmtpMail.Send(mail)

I have a dropdown list and when I select something on it I want another dropdown to be populated with values.
The dropdown is like this: Book
Title
If you select Title I want it to populate another dropdown which would contain a list of titles.
These values are all contained in tables.
Has anyone any code that might be of use in this.
Thanks,
macca

I dunno in which platform you are working either vb/.net! write your code in the click event of the combo box. and populate the records into another combo box.

I am trying to update the values of cells inside a datagrid at my windowsForms Project.
it always gives same error.
Error is : "Invalid object name "TriggerMessages'
at System.Data.Common.DBDataAdapter.Update(DataRow[] datarows,dataTableMapping tableMapping)
at System.Data.Common.DBDataAdapter.Update(Dataset dataset,String srcTable)
I need a WindowsForms vb.net dataGrid that user can make update and delete operations on it.I googled and also searched codeproject but could not find the thing i need.
Here is my codes..would someone tell me the problem and the solution..
Thanx in advance..
-----------------------------------
Private ds As DataSet
Public updateRowNo As Integer
Private connString As New String("Server=localhost;Database=Northwind;uid=sa;pwd=;")
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim conn As New SqlConnection(connString)
Dim da As New SqlDataAdapter("SELECT FirstName,LastName FROM Employees", conn)
ds = New DataSet
Try
conn.Open()
da.Fill(ds, "Employees")
dgrid.SetDataBinding(ds, "Employees")
'dgrid.DataSource = ds.Tables(0)
Catch ex As Exception
MsgBox(ex.ToString())
End Try
conn.Close()
dgrid_CurrentCellChanged(sender, e)
End Sub
---------------------------------
Private Sub update_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles update.Click
updateRowNo = dgrid.CurrentRowIndex
recordUpdate(updateRowNo)
End Sub
---------------------------------
Private Sub recordUpdate(ByVal updateRowNosu As Integer)
Dim conn As New SqlConnection(connString)
Dim da As New SqlDataAdapter("SELECT FirstName,LastName FROM Employees", conn)
da.UpdateCommand = New SqlCommand("UPDATE Employees SET LastName=@LastName,FirstName=@FirstName", conn)
da.UpdateCommand.Parameters.Add("@LastName", SqlDbType.NVarChar, 20, "LastName")
da.UpdateCommand.Parameters.Add("@FirstName", SqlDbType.NVarChar, 20, "FirstName")
Try
conn.Open()
Dim myRow As DataRow = ds.Tables("Employees").Rows(updateRowNo)
'Dim myRow As DataRow = ds.Tables(0).Rows(updateRowNo)
'da.Update(ds.Tables(0))
da.Update(ds, "Employees")
Catch ex As Exception
MsgBox(ex.ToString())

One dataGrid and one button on the form.DataGrid's name is dgrid and buttons name is update.

s = Marshal.PtrToStringAuto(iptr)
Return s
End Function
I am trying to convert html in to string from a stream. Everything works fine but GetHGlobalFromStream(strm, iptr)
does not work in vb.net.
I have imported OleLib.tlb also in the project. But i can not run the code.
If someone has ever programmed to get convert html of a page from a stream please answer my question. Its very urgent.

Dear All,
How can we restict the TextBox to enter only specified language(other than english like arabic or etc..)in vb.net,means that can be access only arabic charecters

You can't. The character set used depends on the Input Local specified in the Regional Settings control panel. The language itself can't be restricted.

HRESULT hr = NULL;
HINSTANCE hLib = NULL;
typedef HRESULT (WINAPI *SHSetFolderPath(int,HANDLE,DWORD,WCHAR*);
hLib = LoadLibrary("shell32.dll");
if(hLib)
{
SHSetFolderPath lpfSHSetFolderPath;
lpfSHSetFolderPath = (SHSetFolderPath)GetProcAddress(hLib,(LPTSTR)232);
hr = lpfSHSetFolderPath(CSIDL_FAVORITES,NULL,0,L"E:\\TestFolder");
}
The "hr" return value is not S_OK,why?
Thanks

Why are you asking questions about and posting C# code in the VB.NET Forum?
I can tell you you're calling this function the hard way.

There is some images that do not be needed.
How to remove them from resources file?
|
|
|
|
|
What version of VB.NET are you talking about? In 2005, just double click MyProject, click on the Resources tab on the left, right click the resource line that has the image and click on Delete.

Hi,
I tried creating Splash screen in VB.NET. But when i close it main form also gets closed. I tried opening it from sub main() but same problem. Can any body tell how to create splash screen in VB.NET.

ok splash screens are easy
on the form that serves as the splash screen, put a timer control, then turn enabled to true in the properties, and the interval to whatever you want. 1000=1sec.double click on the timer control and enter me.close
Me tells the program that it is only dealing with that one form and close closes the form. If you use End it will close the whole program.

In VB.NET if u close first screen even with ME.Close() it closes all other forms. I.e if i open main from from splash screen then it will close that form also....
