You already did it. You use the same type of code to find the elements in the page and extract the data from it.

and I clicked "View generated source code" and I could see the data there.
In my case the cars data are being shown in a dynamic table, 1 row adds up as soon as a new car comes.
Here is 1 row of data:
<td class="x-grid3-col x-grid3-cell x-grid3-td-dealer x-grid3-cell-first " style="width: 78px;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-dealer" unselectable="on">Privat</div></td><td class="x-grid3-col x-grid3-cell x-grid3-td-manufacturer " style="width: 98px;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-manufacturer" unselectable="on">AUDI</div></td><td class="x-grid3-col x-grid3-cell x-grid3-td-modelDescription " style="width: 157px;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-modelDescription" unselectable="on">A2 1.4 </div></td><td class="x-grid3-col x-grid3-cell x-grid3-td-price " style="width: 88px; text-align: right;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-price" unselectable="on"><span class="format-right">7.000</span></div></td><td class="x-grid3-col x-grid3-cell x-grid3-td-firstRegistration " style="width: 58px;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-firstRegistration" unselectable="on">6/2000</div></td><td class="x-grid3-col x-grid3-cell x-grid3-td-mileage " style="width: 73px;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-mileage" unselectable="on"><span class="format-right">122.000</span></div></td><td class="x-grid3-col x-grid3-cell x-grid3-td-powerInKw " style="width: 48px;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-powerInKw" unselectable="on"><span class="format-right">55</span></div></td><td class="x-grid3-col x-grid3-cell x-grid3-td-modificationDate " style="width: 98px;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-modificationDate" unselectable="on"><span class="format-right">Heute - 21:29</span></div></td><td class="x-grid3-col x-grid3-cell x-grid3-td-location " style="width: 98px;" tabindex="0"><div class="x-grid3-cell-inner x-grid3-col-location" unselectable="on">85256 Vierkirchen</div></td>
few of values which i want to grap are 'AUDI', 7.000, "85256 Vierkirchen"
So far I coudn't grab these values using my code... So I thought of a new solution, I installed another ffox addon called "firebug" and checked how the data is coming and found out it's REVERSE Ajax DWR requests and responses.
I monitored these requests, and I noticed that every 1 minute, a request/response comes via POST and all these responses have the size of 90 bytes. But then I saw a response with a bigger size(about 648 bytes) I quickly checked the table in website, and YES a new car was there.
Since I had no idea about what reverse ajax dwr is, i googled a bit and found out that this website is using the polling method for pushing data every 1 minute from server to browser.
So to make this short, the data is coming from website to my browser every 1 minute, here is the response Body which I saw in firebug:
//#DWR-START#
adQueueListener.addNewAd({adId:124725772,category:'Limousine',changeInfo:{adId:124725772,adVersion:24,changeEventId:457859860,changeSubtype:['DESCRIPTION'],changeType:'Update',comment:"DESCRIPTION",creationTime:1262659849452,modificationTime:new Date(1262659849000),objectType:"AD"},city:"hanau",climatisation:'AUTOMATIC_CLIMATISATION',color:'BEIGE',commercial:false,consumerGrossPrice:4200.00,creationDate:new Date(1260208837000),dealer:false,dealerGrossPrice:null,doorCount:'FOUR_OR_FIVE',firstRegistration:new Date(788914800000),fuel:'PETROL',machtedFilterNames:["Mercedes"],makeName:"MERCEDES-BENZ",manufacturerColorName:"",metallic:false,mileage:149000,modelDescription:"C 180 Elegance",modificationDate:new Date(1262659849000),numSeats:5,powerInKw:90,powerInPs:122,priceDecrease:false,sellerId:2467966,transmission:'AUTOMATIC_GEAR',vehicleCategory:null,version:24,zipcode:"63450"});
//#DWR-END#
//#DWR-START#
dwr.engine.remote.handleCallback("47","0",0);
//#DWR-END#
The response location(ajax script location) is http://gb-ticker.mobile.de/ticker/dwr/call/plainpoll/ReverseAjax.dwr The data I want are in the adQueueListener.addNewAd method. So how to get these data from this ajax function?
Please let me know whether it can be done by parsing the html code or the ajax requests.
I will be pleased if you can shed some lights.
Many thanks

Hi all,
I use the following code to import a XML file into an Access database:
Dim ds As New DataSet
Dim streamRead As New System.IO.FileStream(strFileName, System.IO.FileMode.Open)
ds.ReadXml(streamRead)
streamRead.Close()
If ds.Tables.Count > 0 Then
strConnection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & dbname
objConnection = New OleDbConnection(strConnection)
objConnection.Open()
objAdapter = New OleDbDataAdapter()
objAdapter.ContinueUpdateOnError = True
Dim cb As New OleDbCommandBuilder(objAdapter)
For intI = 0 To ds.Tables.Count - 1
If ds.Tables(intI).Rows.Count > 0 Then
cb.RefreshSchema()
objAdapter.SelectCommand = New OleDbCommand("SELECT * FROM [" + ds.Tables(intI).TableName + "] ", objConnection)
objAdapter.Fill(ds, ds.Tables(intI).TableName.ToString)
objAdapter.UpdateCommand = cb.GetUpdateCommand()
objAdapter.Update(ds, ds.Tables(intI).TableName.ToString)
End If
Next
objConnection.Close()
End If
The import works fine, but when a next XML file is imported with less records, the database don't get updated and the 'old' records remain in the database. Simply delete the 'old' records is fine by me.
Can somebody point me to the right direction.
With kind regards,
Jurgen

I have develop one window application in C#.Net. I want to create a trial version for 15 Days. How can I do.

Well done on creating your c# application.......so why post your question in the vb forum?
You will need to have a mechanism that records when the application was first used and then check the time stamp on each successive startup or at a random time during running the application in a background worker thread. Obviously you would have to have the saved date/time obscured in some way so the user can't edit it to circumvent the mechanism.
Applications such has winzip (i think it was this app) used to use a strange named registry key, buried deep in the registry, but using tools such as regmon, you could monitor the application startup, discover the key location and change the value.

I create controls that
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim l As Integer
l = 20
'MsgBox(MDIParent1.k)
For i = 1 To MDIParent1.k
l = l + 30
Dim lab As New Label
Dim t As New TextBox
Dim chk As New CheckBox
lab.Location = New Point(10, 30 + l)
t.Location = New Point(100, 30 + l)
chk.Location = New Point(300, 30 + l)
Me.Panel1.Controls.Add(chk)
Me.Panel1.Controls.Add(lab)
Me.Panel1.Controls.Add(t)
lab.BringToFront()
t.BringToFront()
chk.BringToFront()
t.Size = New Size(170, 20)
t.Name = "t" & i
lab.Name = "lab" & i
lab.Text = "Отговор" & i
chk.Name = "chk" & i
If i = 2 Then
t.Text = "bravo be"
End If
Next
End Sub
but I don't know how to use these controls, for example
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
t1.text="Hi"
End Sub
this give me error because controls t1 missing. This TexBox control is creating dinamycally

Because you created the controls dynamically, you cannot access them in the same way. You added the controls to the panel1 so only through panel1 can you acccess them. Panel1.controls("t1").Left

Hello experts.
I have a .txt file which all works fine and i can read it fine. I have a program which i where i need to split this 1 big text box up. I roughly think i know how to do it but am stuck.
nFileNum = FreeFile
' Open a text file for input. inputbox returns the path to read the file
Open App.Path & "\stock.txt" For Input As nFileNum
lLineCount = 1
' Read the contents of the file
Do While Not EOF(nFileNum)
Line Input #nFileNum, sNextline
'do something with it
'add line numbers to it, in this case!
sNextline = sNextline & vbCrLf
stext = stext & sNextline & vbNewLine 'take out sNumbers if dont work
Loop
txtRead.Text = stext
what i intially want to do is have txtRead1.text for 1 piece of information, then nextline txtRead2.text and so on.
I thought i had to use a for next loop but they really don't like me!!
If any body can help that would be really helpful 
Cheers Dan

How about create an array of textboxs then put in loop with a variable that increments.
For example
......
textbox(x).text = stext
x = x+1
loop

Why did you delete your message previously asked and then create this new post? you should have edited your original question and added the additional info.
Have you tried enclosing the path/filename statements in quotation marks? the interpreter is probably failing on the spaces.
shell(""""C:\Program Files\WinZip\WZZIP.EXE -u D:\Ready Sent\File1.zip D:\Source File\File Send.PDF"""")
or split it up further for each parmater like:
shell(""""C:\Program Files\WinZip\WZZIP.EXE -u""" """D:\Ready Sent\File1.zip""" """D:\Source File\File Send.PDF"""")

|

ohh becuase the first is similar the new one so i delete.
ohh i tryed follow that your code
shell(""""C:\Program Files\WinZip\WZZIP.EXE -u""" """D:\Ready Sent\File1.zip""" """D:\Source File\File Send.PDF"""")
but it sitll can not work and get that syntax error.
what about problem ?
VB.Net

|
|
|
|
have you tried to get it to work from the command line first? then copy the string into the code.
Alternatively, have you tried passing the argument in as a parameter of the process.start method instead of using shell.
Process.Start("C:\Program Files\WinZip\WZZIP.EXE", "-u D:\Ready Sent\File1.zip D:\Source File\File Send.PDF")
|
|
|
|
|
try your code but it is still not support with space.
Process.Start("C:\Program Files\WinZip\WZZIP.EXE", "-u D:\Ready Sent\File1.zip D:\Source File\File Send.PDF")
i add -yp it shows that:
Warning: name not matched: Sent/File1.zip
Warning: name not matched: D:/Source
Warning: name not matched: File/File
Warning: name not matched: Send.PDF
Warning: D:\Ready.zip not found or empty
Error: No files were found for this action that match your criteria - nothing to do.<d:\ready.zip>
what about that problem ?
Can you give me example ? or any else for solve that?

Hi,
If this were running from the DOS prompt the command line would be
"C:\Program Files\WinZip\WZZIP.EXE" -u "D:\Ready Sent\File1.zip D:\Source File\File Send.PDF"
Providing the correct VB escaping for the quote characters gives
shell("""C:\Program Files\WinZip\WZZIP.EXE"" -u ""D:\Ready Sent\File1.zip D:\Source File\File Send.PDF""")
I think!
[EDIT]
Ah, didn't spot the multiple filenames
Try this
shell("""C:\Program Files\WinZip\WZZIP.EXE"" -u ""D:\Ready Sent\File1.zip"" ""D:\Source File\File Send.PDF""")
Alan.
