Dear all,
We have a VB.Net 2003 winforms application.
I have created a datagrid "datagrid1" with 3 columns in it(FirstName, LastName, CheckboxColumn). One of the columns is a checkbox column.
Lets say the user selected 5 checkbox rows(out of 20 rows), I would like to retrieve the FirstName & LastName values for these selected 5 rows from the Datagrid & display it in a listbox. Please advise how can it be done.
Your help is much appreciated.

if you want to retrive name on some button click, use FindControl method of grid view, and find the Checkbox then check which is selected or not.
Hope this will help you.

Dim rowCount As Integer = 0
Dim strname As String
Dim i As Integer

Dim DemoGridItem As DataGridItem
For Each DemoGridItem In DG1.Items
Dim myCheckbox As CheckBox = CType(DemoGridItem.Cells(0).Controls(1), CheckBox)
If myCheckbox.Checked Then
rowCount += 1
end if
next
In the above code how can i store the selected checkbox perticular column in the selected rows?
I want to update that array of columns in the database at a time later.

If you want to avoid popup then you can use overlay functionality, in which one div will on the top of the page which will have all that stuff which your poup will contain.
About caching, its depend what the data that page has, if its static then we can cache the output.

i am tring to search for log files on c:\ using a date range (format 20080725) the file format is lookup20080725.log the other log is detail20080725.log. the logs are created daily and i want to pull
up all files using a start date and a end date. then to display then on a web page with hyper links.
these files are on the server not a pc if that helps.
i am not sure if using a do loop or the for next is better
Dim str As String
Dim en As String
Dim i As Integer
Dim filext As String
str = date1.Text
en = date2.Text
Do Until i = en
filext = File.Exists("C:\lookup" & i & ".log")
i = str + 1
If filext = True Then
End If
Loop
thanks for any help or advice or even a point in the right direction lol

Create an object of stringbuffer class, and use any loop to move accross.
if its exist then add hyper link tag that is <a> and provide the path, else just name of file, no hyper link
somethign ike...
if file exists then
Sb.appendline("<a href="[filepath]" target="_blank">[FileName]</a>")
else
Sb.appendline("[FileName]")

A year ago I created Windows custom control in VB.NET 2.0, which serves as document manager for any Case Management Application, including Customer Billing, Check Writer, etc... It works fine and quite easy to use.
But recently I had to implement same functionality for Web application and control fails to show.
No errors and no results. The control itself use external dll's and classes, including WebBrowser control and mshtml.dll.
If anyone knows how to handle it, any help would be greatly appreciated.
I can send objects and a sample of using it.

Hi friends
First of all I would like to thank people here on codeproject for helping me whenever I need help. I am hopefull that now also all of you will help me. Today I got a special scenario which I am applying in my application.
I have 2 text boxes to enter zipcode, In first text box when ever user enters some data and presses tab and on getting focus on the second textbox, the second textbox must show data based on the values entered in the first textbox like what we see in google suggest.
For example when user enters 5 digit zipcode in 1st textbox & presses tab key the focus will be on 2nd textbox and immediately 2nd textbox must show names of peoples based on the zipcode entered in 1st textbox, like how we see in google suggest.
For further clarification please mail me back. Hope some one will help me. Thanks in advance

wish i coulda gotten that in college..i may have become a computer engineer, though without actually doing any of the work i dont think i would have been one for long. i guess people just think we sit in small fabric covered box all day and get a paycheck and dont actually have to do or know anything. i know thats the opinion around here most of the time (until we put a build out then we do things but what we do is never right)

I have a simple ASP webservice that performs a SELECT query against a database, and then an INSERT statement on the same database/table. The problem arises at the time when we create the second OleDB connection object and attempt to Open() it. The connection string is exactly the same for both connection objects. Another intersting thing is that this code works fine when it is used in a Windows Form project. I'm using VS2003.
Here's the code used for both attempts:
try
{
cnOleDBSDE = new OleDbConnection();
cnOleDBSDE.ConnectionString = "Data Provider=" +DBProvider+ ";"+
"Provider=" + DBShapeProvider + ";" +
"Data Source=" + DBName + ";" +
"Pooling=" + Pooling.ToString() + ";" +
"User Id=" + UserId + ";" +
"Password=" + Password;
cnOleDBSDE.Open();
}
Here's the connection object data from the immediate window when .Open() is called succesfully:
cnOleDBSDE
{System.Data.OleDb.OleDbConnection}
base {System.Data.Common.DbConnection}: {System.Data.OleDb.OleDbConnection}
ConnectionString: "Data Provider=MSDAORA.1;Provider=MSDataShape;Data Source=sdeprod;Pooling=False;User Id=ACOUSINS;Password=djhf6li"
ConnectionTimeout: 15
Database: ""
DataSource: "sdeprod"
Provider: "MSDataShape"
ServerVersion: 'cnOleDBSDE.ServerVersion' threw an exception of type 'System.InvalidOperationException'
State: Closed
And the connection object data from the immediate window when .Open() throws an OleDB exception:
cnOleDBSDE
{System.Data.OleDb.OleDbConnection}
base {System.Data.Common.DbConnection}: {System.Data.OleDb.OleDbConnection}
ConnectionString: "Data Provider=MSDAORA.1;Provider=MSDataShape;Data Source=sdeprod;Pooling=False;User Id=ACOUSINS;Password=djhf6li"
ConnectionTimeout: 15
Database: ""
DataSource: "sdeprod"
Provider: "MSDataShape"
ServerVersion: 'cnOleDBSDE.ServerVersion' threw an exception of type 'System.InvalidOperationException'
State: Closed
I don't see any differences. Finally here's the error:
{"Data provider could not be initialized."}
[System.Data.OleDb.OleDbException]: {"Data provider could not be initialized."}
Data: {System.Collections.ListDictionaryInternal}
HelpLink: null
InnerException: null

I tried Googling and found people with similar issues from years ago, but no resolutions. Any ideas?

I'm guessing that you have the Oracle client installed correctly on your desktop (which would explain why your code is working in a Windows Forms application) but not installed correctly on your web server. Check and make sure you can connect to your database directly from the web server (for example, use SQLPlus or something like that directly from the web server console). If you can't, then you'll have to review your Oracle client installation there.

The thing is, I can connect just fine the first pass. I'm using the Visual Studio development server that starts automatically on my machine when I go into debug so I assume it uses the same credentials as my local user logon info.
