User this :
string filename = "x.dat";
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AppendHeader("content-disposition", "attachment; filename=" + filename);
HttpContext.Current.Response.ContentType = "application/exe";
HttpContext.Current.Response.BinaryWrite(filebytes);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.Close();
You can use Response.TransferFile/ or directly Response.Write based on your content.

Can anyone please help me in differentiating between Remote Procedure Call and Web Services.
|
|
|
|
|
Actually Web Services are a part of Remote Procedure Calls. Web services uses Http Request/ response (SOAP based) to call a remote procedure.
Other than that you can also invoke RPC using normal Remoting.
|
|
|
|
|
Remote Procedure Call is the generic name for invoking methods (originally, Procedures) in other computers.
.Net Remoting, Web Services, WCF and other technologies are, in practice, RPC technologies.
You can also see RPC used for Com+, as Com+ components can be activated remotelly.

Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customerrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customerrors> tag should then have its "mode" attribute set to "Off".
<configuration>
<system.web>
<customerrors mode="Off">
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customerrors> configuration tag to point to a custom error page URL.
<configuration>
<system.web>
<customerrors mode="RemoteOnly" defaultredirect="mycustompage.htm">

Are you sure you have installed .NET 3.5 in the production environment, means where you are publishing the website ?
also reinstall the Asp.net again to have proper permission to all the system dlls.
use
aspnet_regiis /i

Hi all
I have been coding .NET for a couple of years now, and would like to expand my knowledge on the way that I do things. Someone suggested using a framework like Spring.NET. Has anybody used this framework before? Any comments, good or bad would be appreciated. I have searched for a while now and haven't come across some decent articles. Not sure on what part of Spring.NET I need to start looking at. I did post on their forums, but no replies.
I am looking for a decent validation framework. Spring.NET has a validation framework that works well across all layers. I have gone through the code and I can only find code for front end validation, no validation for business object properties. If any body wants to share knowledge here it would be appreciated.
Thanks

Response.Redirect will not give you response_code it will only redirect page to given link.
You can use httpwebrequest and httpwebresponse class to get response_code.

I think You are using the third party for credit/debitcard values.
What is the merchant name You are using?
Depending on the third party the code changes..!
You have capture the response..!
This Is not the way of capturing the value.
You need to use Stream reader and http object response..!
Check this Link it may help..!

If you are only bothered about the Response, dont use Redirect. Redirect actually navigates to the page, so if you use it, your own contextual response will get modified with the response.
So if you what to get the response, you need to invoke another HttpRequest to the web path.
string url = "https://secure.merchantonegateway.com/api/transact.php?id=response_code"
HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
using (StreamReader sr = new StreamReader(objResponse.GetResponseStream()))
{
result = sr.ReadToEnd();
sr.Close();
}
Now result will hold the Response.
I think this is what you require.

Hello ,
I have executed the code the if we give a valid credit card number also the result is the same. so is there any other ways . The responsecode is always 300.
Thanks

I have a GridView where I can export to excel file.
In the beginning of the page where gridview is, I have the following:
<b>Bem vindo <% Response.Write(Session["nome"].ToString()); %>!</b>
Now I've tested the export funcionality again, and having the following error:
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
I googled about it, and looks like because Response.write does not allow the export encoding operation perform correctly, so I commented that line, and now its working again.
So I'm wondering, I really want to use that line. How do I do it? Is it possible?
Many thanks.

Response.Write is idiocy in this context. Just remove it.
