Hi,
Actually, Excel and RTF (RichTextFile) use different structure!Actually, you can use the Excel Object Library to access and manage your excel files (check this article Opening and Navigating Excel with C#[^] hope it helps.
Do you want to open it as read-only or for editing?
good luck and happy new year.

To put it simply you don't display an Excel file in a RichTextBox, this control is really only designed to display RTF and plain text files.
I think your best option would be to invest in a 3rd party control designed to display Excel files such as those from Spreadsheet Gear[^].

I am trying to build a VB.NET windows app which gets cars info from a webpage(webapplication) that has a username and password.
I was able to programmatically login to this webpage(by automatically populating the input boxes) And after I logged in, I could view the cars data in browser and I did "View Source" but the cars data (such as car model, brand, color etc..) were not viewable in the page source code. So how can I read these data with my application?
I hope my question was clear and literally need some help.
Thanks

This is an example of calling a webpage and getting the ip address from the source - i use it as part of my dynamic dns client that i made.
Dim Req As HttpWebRequest = WebRequest.Create("http://www.whatsmyip.us/")
*****************************************************************
** if you need to pass credentials then do this line **
Req.Credentials = New NetworkCredential("USERNAME", "PASSWORD")
*****************************************************************
Dim rs As New StreamReader(Req.GetResponse.GetResponseStream(), System.Text.Encoding.GetEncoding("utf-8"))
Dim s As String = rs.ReadToEnd 'you know now have the entire source in variable 's'
rs.Close()
rs.Dispose()
rs = Nothing
Req = Nothing
Dim IP As String = Regex.Match(s, "\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}").Value

That code will only work for a web page that forces the browser to show a login dialog box. For all others (most) websites, you'll have to get the login page, find the textboxes in the returned HTML, fill them in and submit the page back. No, I don't have an example.

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
