Standard Question #2: What does the code look like that is doing the pings?

Hi,
if the PING utility, with all its options, does not satisfy your needs, you may have to create your own; you then could have a look at the System.Net.NetworkInformation.Ping class

Dim c As String = System.Convert.ToBase64String(ctr)
Return c
End function
and following code for decrypt the value for showing in textbox
Public function decryp(ByVal c As String) As String
Dim b1 As Byte() = System.Convert.FromBase64String(c)
Dim f As String = System.Text.ASCIIEncoding.ASCII.GetString(b1)
Return f
End function
but sir i am unable to decrypt my dataset with the help of this function to show the record in datagridview.so please help me for decrypt the dataset.

Well, I downloaded the code from that article, it compiled and yeah it is a Windows Forms Application. You have to go through the complete article to understand how to implement paging in DataGridView.
Good Luck!!

You call converting a string to Base64 encrypted? That's not encrypted at all.
The code is correct as far as I can see. You're going to have to double-check what you're passing into each method and what you're getting back.

|
|
|
hi sir ,
send code in decrypted dataset in database
please sir
|
|
|
|
|
No, I'm not giving you any code.
You've already got the code that does the job. For some reason, you've either not following what youre passing into the encryption/decryption methods or you're not storing or retrieving the data from the database properly.

I need Readonly ComboBox in vb.net windows application, for this requirement i used to use textbox & combobox together in the same place.
TextBox Properties
ReadOnly=True
TabStop=False
ComboBox Properties
AutoCompleteMode=SuggestAppend
AutoCompleteSource=ListItems
TabStop=True
in ADD/EDIT events set ComboBox Enabled=True, if the event is done ComboBox Enabled=False
this is my code
Private Sub ComboBox1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs)
Handles ComboBox1.GotFocus
TextBox1.Visible = False
End Sub
Private Sub ComboBox1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs)
Handles ComboBox1.LostFocus
TextBox1.Visible = True
End Sub
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles ComboBox1.SelectedIndexChanged
TextBox1.Text = ComboBox1.SelectedItem().ToString
End Sub
in design TextBox on top of the ComboBox, can see only the ComboBox Button.
Please give me any simple solution for this....

Your logic, at a form level, seems wrong. When you display the dialog you should know if CRUD is required at which point you display a combo so the user can edit the data. If the user is opening the form as RO then either disable the combo or display a textbox with the required value.
I cheat, if the user does not have CRUD rights on the form/data I make the save button invisible/disabled. The user can do what they like, just can't save the results.

My point is why are you making the combo readonly. Simply disable the save button.
If you insist on readonly then have a textbox on display when the form is in the view only mode and swap for a combo box on the add/edit event. If the act of entering the combobox changes the state of the form to edit mode then why are you bothering to have it readonly.

I assume you want to make the combox box read only, so that user can't type in. For that try changing the DropDownStyle property to "DropDownList"

I really, really hate missing the bloody obvious, all the faffing about with text boxes and events must have confused me, change the style, of course. mutter mutter bloody idiot
|
|

Oh please calm down.. I guessed the issue because I know how some newbie ask the question. They want to do something else and ask something totally irrelevant.

you can change the dropdownstyle property of combobox to dropdownlist. Then the user will not be able to change the content.
|
|
|
|
|
that is ok but i want the same style in dropdown not in the dropdownlist
thanks for your reply

ds = new DataSet();
RBLL = new ReportBLL();
ds = RBLL.ShowCustomersReport(RBLL);
if (ds.Tables[0].Rows.Count != 0)
{
reportViewer1.Visible = true;
reportViewer1.ProcessingMode=Microsoft.Reporting.WinForms.ProcessingMode.Local;
reportViewer1.LocalReport.ReportEmbeddedResource = @"C:\Inetpub\wwwroot\Tirumala Gruha Nirman\Tirumala Gruha Nirman\CustomersContactList.rdlc";
reportViewer1.LocalReport.DataSources.Clear();
bindingSource1.DataSource = ds.Tables[0].DefaultView;
rpt.Name = "Customerscontactinfo_sp_showcontactlistofcustomers";
reportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WinForms.ReportDataSource("Customerscontactinfo_sp_showcontactlistofcustomers",bindingSource1));
// reportViewer1.LocalReport.DataSources.Add(rpt);
reportViewer1.DocumentMapCollapsed = true;
reportViewer1.LocalReport.Refresh();
