Hi.
I have created a Typed Data Set using visual studio 2005 designer. I drag-dropped a table from database and it created a typed data table into it. When I insert data into this table using TableAdapter generated by Visual sudio designer it does not insert in physical database.
I can retrieve it till application is running and lost as the inserted data is in memory not in physical database.
here is the sample code I wrote:
DefectTrackerDataSetTableAdapters.
tblDefectsTableAdapter ta = new DefectTracker.DefectTrackerDataSetTableAdapters. tblDefectsTableAdapter ();ta.InsertDefect(
Convert .ToInt32(txtDefectNo.Text), "MQC" , dpAssignDate.Value, "Open" );
1. In the assembly that implements the type(Console), look up the method being called
in the metadata.
2. From the metadata, get the IL from this method and verify it.
3. Allocate a block of memory.
4. Compile the IL into native CPU instructions: the native code is saved in the memory
allocated in step#3.
5. Modify the method's entry in the Type's table so that it now points to the memory
block allocated in Step#3.
6. Jump to the native code contained inside the memory block.

Hi,
Whenever I run sfc /scannow it asks for a CD. How can i point it to some other path where my installation source files reside.
In Registry using regedit locate
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Setup\SourcePath
Set its value to the location where I386 foler is located. Provide the parent folder path of I386 and not of I386 itself.
Also update ServicePackSourcePath and add to Installation Sources as well.

here is the working code:
< form id ="form1" runat ="server">
< div >
< asp : TextBox runat ="server" ID ="txt1" TextMode ="MultiLine" />
< asp : HiddenField runat ="server" ID ="hidSelectedText" />
< asp : Button runat ="server" ID ="showselected" Text ="Show selected" OnClientClick ="doselection();" OnClick ="showselected_Click" />
< script type ="text/javascript">
function doselection()
{
if (window.getSelection){
txt = window.getSelection();
}
else if (document.getSelection){
txt = document.getSelection();
}
else if (document.selection){
txt = document.selection.createRange().text;
}
else{
alert(
'selection not supported' );}
document.getElementById(
'<%=hidSelectedText.ClientID %>' ).value = txt;}
</ script ></ div >
</ form >

protected void showselected_Click( object sender, EventArgs e)
{
Response.Write(hidSelectedText.Value);
}
Go to

Expand "Projects And Solutions"
Check "Track Active item in Solution Explorer"
Use
Server.UrlEncode
System.Diagnostics.
Process objDocProcess = new System.Diagnostics. Process ();objDocProcess.EnableRaisingEvents =
false ;objDocProcess.StartInfo.FileName =
@"C:\Excel.xls" ;objDocProcess.Start();
The XmlSerializer can
be used when you need the data in the object to be stored in an XML Format. However,
this serialize has the limitation that it can serialize only the public fields of
an object.
The SoapFormatter is ideal in scenarios
where you need interoperability. This is ideal in applications spanning heterogeneous
environments.
The BinaryFormatter generates a
very compact stream when an object is serialized as compared to the other two techniques
and hence is useful when data needs to travel electronically across the wire. This
is appropriate when the applications do not involve heterogeneous environments.
Use the HtmlInputFile class, which you can declare an instance of with an <input type="file" runat="server"/> tag. The following example is a complete ASPX file that lets a user upload an image file and a comment descibing the image. The Upload_Click method writes the image and the comment to a table named Pictures in a SQL Server database named MyPictures.
<
form id ="Form2" enctype ="multipart/form-data" runat ="server">protected void Upload_Click( object sender, EventArgs e)
int len = Upload.PostedFile.ContentLength; byte [] pic = new byte [len];
Upload.PostedFile.InputStream.Read(pic, 0, len);
// Insert the image and comment into the databaseSqlConnection connection =
new SqlConnection( "server=localhost;database=mypictures;uid=sa;pwd=" ); try{
connection.Open();
SqlCommand cmd =
new SqlCommand( "insert into Pictures " + "(Picture, Comment) values (@pic, @text)" , connection);cmd.Parameters.Add(
"@pic" , pic);cmd.Parameters.Add(
"@text" , Comment.Text);cmd.ExecuteNonQuery();
}
finally {
