How To Optimize Gif Images ??? It's So Cool To Answer This ???

Is it right, that the MsgBox() function from asp.net 2.0 cannot be used to show a messageBox in the browser? It only works well on development systems, where server and browser are on the same system? If yes: sorry for my naivity. Blush | :O

Plz treat this post seriously.

PS. I know how to display on the browser, but I thought MsgBox() does this functionality for us per hidden script, like viewstate for example.

There is no such thing. MsgBox is a hangover from VB6, in VB.NET, in WinForms. It has nothing to do with ASP.NET.

Correct, because it runs on the server. You can't do stuff like that in C# or VB.NET and have them appear on the client. You need instead to use the alert function, which is a javascript API and thus can run on the client ( so you need to inject javascript into your page, so it appears on the client )

No.

How can I get if the File download was successful or not.

I m simply using -
Response.Redirect(url)

The file download dialog box contains Save, Cancel.
How could I know that User clicked Cancel?

Is there any workaround?

I hv also tried

Response.Clear()<br />
Response.AddHeader("Content-Disposition", "attachment; filename=" & file.Name)<br />
Response.AddHeader("Content-Length", file.Length.ToString())<br />
Response.ContentType = "application/octet-stream"<br />
Response.WriteFile(file.FullName)<br />
Response.End 'if file does not exist

But how could i get the Result of Download operation?

I'm trying to configure log4net to work in my web project in visual studio 2005. I tried to follow most the configuration example in the web but my project don't have assembly.cs file, so where should i tell the application to read my log4net configuration.
I put the config in the default web.config, and try to create the log in ExampleLog.log, but the log never appear. How can I tell the application to parse my config. I try putting log4net.Config.XmlConfigurator.Configure(new System.IO.FileInfo("web.config") in Global.asax, not working too.

<configsections>

<log4net debug="true">

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">

sql server transactions

I'm using asp.net 2.0 and sql server 2000. I'm using a transaction to wrap the execution of 2 insert commands on the sql server together. On the development system everything works fine. On the target system it executes the 2 inserts properly but then displays the error message:

Sqltransaction is finished and cannot be used anymore

the stack:
System.Data.SqlClient.SqlTransaction.ZombieCheck() +701167
System.Data.SqlClient.SqlTransaction.Rollback() +120
kurz.GV1_RowCommand(Object sender, GridViewCommandEventArgs e) +2901
System.Web.UI.WebControls.GridView.OnRowCommand(GridViewCommandEventArgs e) +104
System.Web.UI.WebControls.GridView.HandleEvent(EventArgs e, Boolean causesValidation, String validationGroup) +76
System.Web.UI.WebControls.GridView.RaisePostBackEvent(String eventArgument) +200
System.Web.UI.WebControls.GridView.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +7
System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +11
System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +170
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5612

does it try to make a rollback? but the things are inserted properly.
And then it makes the funny Zombiecheck and maybe found one.

Did anybody solve a similar issue? Thanks in advance. Wilfried.

ok thats the code: I execute it in the gridview_RowCommand()
and on the development system everything is great.

sqlKont = "Update tbnKontBib set fest=fest+ CONVERT( money," & "'" & Komma2Punkt(diffFest) & "') " & _
"where bh='" & Session("bHalle") & "'"

sql = "Insert into tbOrder(artnr, odatum, bh, oanz, opreis, bhoper) Values( " & _
"'" & artnum & "'" & "," & _
"'" & Date.Now.ToShortDateString & "'" & "," & _
"'" & Session("bHalle") & "'" & "," & _
"'" & anzBest & "'" & "," & _
"CONVERT( money," & "'" & Komma2Punkt(preis) & "')" & "," & _
"'" & Session("bUser") & "')"

'Ausfuehrung mit Transaction
Try
t = conn.BeginTransaction
cmd = New SqlCommand(sqlKont, conn)
cmd.Transaction = t
erg = cmd.ExecuteNonQuery()
If erg <> 1 Then 'Fehler
MsgBox("K-Fehler in Bestellung! Bitte Administrator benachrichtigen!", MsgBoxStyle.Critical, "!!! Achtung !!!")
t.Rollback()
GoTo ende
End If

cmd = New SqlCommand(sql, conn)
cmd.Transaction = t

hi,

I have a grid view which i am creating dynamically in the code behind with hyperlink fields.on click of each hyperlink field i have to open up a new pop window using javascript and passing multiple parameters. I am doing something like this. But the problem is in my page, the value of the parameters that i am getting is {0} and {1} instead of their actual values. Any solutions how i can go about this?
bfield.DataTextField = DataCol.ColumnName
bfield.HeaderText = DataCol.ColumnName
bfield.DataNavigateUrlFields = crfields
bfield.DataNavigateUrlFormatString = "javascript:void(window.open('mypage.aspx?my_id={0}&name={1}',"",'width=270,height=300,top=200,left=200'));"
