There are a couple of options that you may try:
+ Use a third party component for example Aspose.Cells to support working with Excel.
+ Use the Automation (not recommeded though it works).
+ Use the ADO.NET[^] to read/insert/update data in the excel sheet.

Hello,
I am playing with ways to set query command in VB.NET to retrieve set of records from SQL DB. I know basic sytanx and it works well.
However I can not get this to work.
I have a textbox where users enters a name of broker and then when clicks Search button, data grid gets populated with all broker info. This works well if name that user entered exists in SQL DB.
My goal was to have this same result, but when users enters partial name too.
Example: Full broker name: Mike Tyson
Partial broker name: Mi
This is the string I used but it does not work:
Dim strSQL As String = "SELECT * FROM broker
where name like '" & strName& "%'"
This returns error : Index was outside the bounds of the array.
If I enter this command directly in SQL Analyzer as
SELECT * FROM broker where name like 'Mi%' it works just fine.
What I am missing???

Hi,
How we can detect browser-close (x) event in asp.net?
Anybody has some idea .please let me know

There's no good way to detect the close button of the browser, but there are some events of the window object like onbeforeload,onload which are close to what you want.

Anybody know of any good free ASP hosts out there? (Besides Brinkster)
Don't need a lot of storage, just something stable to test on.

Hi David,
I had hosted my asp site last year in domaindlx.com. I've heared, somebody else has purchased the site so I don't no whether they are still in free hosting or not. Anyway, ASPSpider.net is still providing free space without any banner.
for asp - domaindlx.com
for asp.net (2003) www.aspspider.net

as a newbie, I have developed a simple administrative app that lists members of our mailing list. ON the viewing page, checkboxes are dynamically listed along with the member info. When one checks a box and clicks 'edit', i want the item checked to open into the edit page with it's appropriate data. Problem: I can get the checkbox associated to an id number on the viewing page. I just can't seem to figure out how to send that id and data to the edit page. any help or suggestions would be great. can provide code examples if needed.

in the querystring if it's just simple data...

From viewing page you can use code similar to this
Dim trans_id As Integer
Dim dgrCode As Label = E.Item.FindControl("lblCode")
trans_id = CType(dgrCode.Text, Integer)
Server.Transfer("EditList.aspx?&trans_id=" + trans_id.ToString(), True)
which does this: reads value from control named lblCode.
Since I needed to transfer this value to next page as integer, I casted it.
Last line of code redirects user to "edit list" page along with value from the control
In Edit List page under Page Load or somwhere else have line similar to this.
lblTest.Text = Request.Params.Get("trans_id")
What this does: it reads a parameter sent from viewing page and assign its value to text box.
I hope this gives you the general idea

I truly appreciate your solution, just wish i could figure out how to implement it. i should have mentioned i'm developing in c#. Here's what I've tried to do with your sample:
--this is in my Page_Load---
--creates an instance of a checkbox and dynamically populates inline with the list of users and sets its value to the same as the pk of the associated dataset---
CheckBox cboCheck = new CheckBox();
cboCheck.AutoPostBack = false;
cboCheck.ID = dsUserInfo.Tables[0].Rows[intCtr]["intMailIDpk"].ToString();
---Event Handler
public void btnEdit_Click(object sender,System.EventArgs e)
{
--->getting error message at this line: Object reference not set to an instance of an object.--
Int16 ckID = Convert.ToInt16(cboCheck.ID);
cboCheck.ID = Convert.ToString(cboCheck.FindControl("ckID"));
Server.Transfer("addedit.aspx?&ckID=" + ckID.ToString(), false);--probably need to user Response.Redirect here, you think??--
}
any help is greatly appreciated. i'm sure i'm just one line of code off here, and then my app works great.

Iam using livecontrols, but a sometimes the browser put this message..
The server viewstate cache has timed out..

I have the following DataList
<div style="overflow:scroll;">
<asp:DataList ID="dlAvatar" runat="server" DataKeyField="FileName" RepeatLayout="Flow" RepeatDirection="Horizontal" SelectedItemStyle-BorderStyle="Inset" >
<ItemTemplate>
<asp:ImageButton ID="imgAvatarSelect" runat="server" OnCommand="Buttons_CommandEvent" ImageUrl='<%# Eval("FileName") %>' CommandArgument='<%# Eval("FileName") %>' CommandName="Select"/>
</ItemTemplate>
</asp:DataList>
</div>
When I use Inline for the "CommandArgument" My onCommand event wont get fired, but when I take it out it works fine.
I I found the control like this inside my code behind:
//void dlAvatar_ItemCreated(object sender, DataListItemEventArgs e)
//{
// int i = 0;
// object a = e.Item.FindControl("imgChoose");
// ImageButton a2 = a as ImageButton;
// if (a2 != null)
// {
// a2.CommandArgument = ((AvatarPicture)e.Item.DataItem).FileName;
// }
//}
but, it finds the control and sets the value. but the commandArgument never changes its value.
And yes, its commented out because it wasnt working.
Any ideas?

+ Are you sure you want to use the imgChoose or imgAvatarSelect id?
+ Here, you are trying to set the CommandArgument property of the imagebutton in both the ItemCreated handler and the data binding expression. And you may already know that the ItemCreated event happens before the data DataBound event where the binding expression is normally executed. So if you want to use the ItemCreated event, you should not use the data binding expression, otherwise the CommandArgument property will be reset.

I tried at just usiing the data binding expression. And it wont fire. But if I delete the CommandArgument it doesn't fire. ( OnCommand event )
Maybe I should create the the DataBind event, that might be a work around.
I did the ItemCreated out of desparation.

Normally, you only need to use the data binding expression to simply set the CommandArgument property of the ImageButton. Have you tried using the ItemCommand event of the DataList control and see if it is fired? Have you viewed the page source and checked the id/name of the imagebutton?

Ok so I changed the Created to be like this:
void dlAvatar_ItemCreated(object sender, DataListItemEventArgs e)
{
int i = 0;
object a = e.Item.FindControl("imgChoose");
ImageButton a2 = a as ImageButton;
if (a2 != null)
{
//a2.CommandArgument = ((AvatarPicture)e.Item.DataItem).FileName;
a2.Command += new CommandEventHandler(Buttons_CommandEvent);
a2.Click += new ImageClickEventHandler(btnAdd_Click);
}
}
it find the control fine. and I add the handlers fine. no errors. But the Image is never posting back. This is just unreal. Is there a property that has to be set to allow posting back?
I'm caught in a nightmare
And to add. I put a regular button on the form and its not posting back.
This page belong to a master page. Do you have any idea why a page wont post back?

Thanks for helping min.
The reason was, my master page was set to "get". I changed it from "get" to "post" and it works fine.
I guess I had a brain fart.
thanks,
