hi
There is a property for asp Image control called altername text.
This text will display if no image url specified.
So set the url for ur image if it is availble only.

Write a function that checks the database value is empty. If empty then replace that with another image not found image. If you are binding data on datagrid then use itemdatabound event for setting the image.
private string GetImagePath(string DbValue)
{
string strReturn = string.Empty;
if ( DbValue == "" ){
strReturn = "YourNotFoundImage.gif";
}
else
strReturn = "CorrrectImage.gif";
}
Call a function like this when data is binding from DB

What about converting binary to string and passing to the function ? Try This Link[^]

Hi
There is one attribute called as 'ALT' tag to describe your image. This means, that the text is meant to be used when the image is not visible on the page.
Hope you got it.

Hi,
You can create a "view" in sql server 2005 from 2 tables.
And use that view to create the report.The view here will act as a single table.

Hi,
I dont know websites explaining SQL server views.
I think you know how to create crystal reports from tables.
So...
1.Open MS Sql Server Management Studio
2.Navigate to your database
3.There will be a treenode "Views" right click on it.
4.Select New View
3.Select the tables that you want to include.press Add
Give your condition for the view.
dont think it is difficult.try yourself it is very very easy...

HI
Thanku I created a view how to use it form userside or the query which is generated is to be used
came out of hardwork
|
|
|
|
|
Hi
Oh... good You are Fast...
The view you created will act like a table.
No need to use the query generated.
Save the view with a name.
then eg:
SELECT * FROM MyView
will return all the data from the view.
I think now you are femiliar withit...

This code is collected from "http://forums.asp.net/t/956392.aspx"
Export to Excel in ASP.NET is a very common feature, which I'm sure everyone who has worked in ASP.NET would have had the chance to implement.
Whenever we choose the Export to Excel option from our Application, a dialog box pops us with the option to Open or to Save.
By chance if the user checks off the option "Always ask before opening this type of file" that is shown in the dialog box, from next time the user will not be able to see the dialog box. Instead, the excel file opens up in the same window.
To set back this option, the following steps can be followed:
1. Go to Windows Explorer.
2. On the Tools menu, click Folder Options, and then click on the File Types tab.
3. From the Registered file types list box, select the XLS extension, and then click Advanced.
4. In the Edit File Type dialog box, set the Confirm open after download to selected.
5. Make sure the Browse in same window option is not selected, and then click OK.
The above steps will make sure that we get the dialog box as shown above. However, since this is an option set at the client computer, these steps cannot be mandated to be followed in every computer that browses the application.
So, from the code level, we must make sure that the excel file is opened in a separate window. One possible option for this is to Save the file to the web server, and then open the file in a separate window.
The code for this is given below:
private void ExportToExcel(DataGrid dgExport)
{
try
{
string strFileName = String.Empty, strFilePath= String.Empty;
strFilePath = Server.MapPath(@"../Excel/") + "ExcelFileName" + ".xls";
if (File.Exists(strFilePath))
{
File.Delete(strFilePath);
}
System.IO.StringWriter oStringWriter =new StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);
StreamWriter objStreamWriter;
string strStyle =@" .text { mso-number-format:\@; }
";
objStreamWriter = File.AppendText(strFilePath);
dgExport.RenderControl(oHtmlTextWriter);
objStreamWriter.WriteLine(strStyle);
objStreamWriter.WriteLine(oStringWriter.ToString());
objStreamWriter.Close();
string strScript = "window.open('../Excel/" + "ExcelFileName" +
".xls','dn','width=1,height=1,toolbar=no,top=300,left=400,right=1,
scrollbars=no,locaton=1,resizable=1');";
if(!Page.IsStartupScriptRegistered("clientScript"))
{
Page.RegisterStartupScript("clientScript", strScript);
}
}
catch(Exception)
{
//Handle Exception
}
}
In the above method, the file is saved to the Web Server inside the folder "Excel". Of course, this folder must have write permissions for the user. But it will definitely ensure that the excel file is opened in a new window in the client computer.
**** I think it helps U ****

Try This:
#Region "Export To Excel Button Click Event"
Protected Sub cmdExportToExcel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdExportToExcel.Click
Dim sw As StringWriter = New StringWriter()
Dim htw As HtmlTextWriter = New HtmlTextWriter(sw)
Try
Dim ml_strFileName As String = ml_strSaveFileName
Dim attachment As String = "attachment; filename=" & ml_strFileName & ".xls"
Response.ClearContent()
Response.AddHeader("content-disposition", attachment)
Response.ContentType = "application/ms-excel"
Gridview1.RenderControl(htw)
Response.Write(sw.ToString())
Response.End()
Catch ex As Exception
Finally
If Not sw Is Nothing Then
If Not htw Is Nothing Then
sw = Nothing
htw = Nothing
End If
End If
End Try
End Sub
#End Region
#Region "VerifyRenderingInServerForm"
Public Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
End Sub
#End Region
Hope this helps u???

Hi there,
Some third party products can do that. Check out a tool called StateMirror.

MyProc.StartInfo.FileName = strPathFile;
MyProc.StartInfo.UseShellExecute = false;
MyProc.StartInfo.RedirectStandardError = false;
MyProc.StartInfo.RedirectStandardInput = false;
MyProc.StartInfo.RedirectStandardOutput = false;
MyProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
MyProc.StartInfo.Arguments = @" -i -h 127.0.0.1 -p 5432 -U postgres -d vietnamairlines -v " + '"' + @"C:\abc.backup" + '"';

Some people give me this Line code put behind MyProc.Start();
MyProc.StandardInput.WriteLine("my password");
But it still not Ok !
Some body tell me ??????

I am prettysure it would need to go before the waitforexit, but you might need to pause for a second before you write it. So maybe something this would work:
MyProc.Start();
Threading.Thread.Sleep(1000);
StreamWriter myStreamWriter = MyProc.StandardInput;
myStreamWriter.WriteLine("my password");
myStreamWriter.Close();
MyProc.WaitForExit();
Hope that helps.
