How to store data from one table to another table in different databases using webservices?
|
|
|
|
|
In .net fetch data in a DataSet and from your web service return this DataSet.
then you can use this DataSet.
for example using asp.net i created a webservice which is fetching data from Sql server then
I am passing this data to mysql server.
Do not hesitate for further question.

hi guys,
i'm using asp.net to build web application.
how can i store image in sql server express edition, and display it
at the web.
|
|

|
|
Store an image, or any binary information in a varbinary(max) column. In order to store or retrieve it you must use a byte[]. In order to display it you can create a special ASPX that overrides the existing render process and writes out binary information instead.

hi,
i new to asp.net
i still cant understand about "create a special ASPX that overrides the existing render
process"....
can you pliz show me just VERY VERY simple example on how to display the image.
|
|
|
|
|
Create an aspx page, remove all markup except the @Page tag, and use BinaryWrite to output the image data:
int id = int.Parse(Request.QueryString["id"]);
byte[] imageData = YourDataBaseCallToGetImageData(id);
Response.ContentType = "image/jpeg";
Response.BinaryWrite(imageData);
Put the address of the page as src in an image tag:
<img src="ShowImage.aspx?id=42">

Seriously, you'll have to be more specific. You might also want to read up on Design Patterns.

You can use a regular expression that matches text in apostrophes. Use the pattern "'(.*?)'".

how to "split phrase" from search "string in texbox" while user serch something
so if know abt this explain it
thanking you.

Put quotes instead of the apostrophes in the pattern.
Use the Regex.Matches method with the input string and the pattern as arguments. This returns a MatchCollection object that contains the matched strings.

I've been trying to get the ASP.NET login control to work with my own-defined authentication method, but couldn't.
The MSDN documentation says to put the authentication logic within the Login.Autheticate event stub. Now, I've done that; and below is the event handle for the login control.
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
UserManager manager = new UserManager();
if (manager.AuthenticateUser(Login1.UserName, Login1.Password))
{
User user = manager.GetById(Login1.UserName);
GenericIdentity identity = new GenericIdentity(user.UserName);
GenericPrincipal principal = new GenericPrincipal(identity, new string[] { user.Role });
Thread.CurrentPrincipal = principal;
e.Authenticated = true;
Label1.Text = Thread.CurrentPrincipal.Identity.Name;
}
else
e.Authenticated = false;
}
The problem is the LoginName control on the page does not display the authenticated user name, nor does a label control i placed on the page to do that ask.
Any tips!
