If IIS is installed after the. NET Framework, ASP. NET must be
Registered with IIS by choosing START | run and entering
Following command:

% Comspec %/K % WINDIR %/microsoft.net/framework/v1.1.4322/aspnet_regiis.exe-I
 
Otherwise, attempting to run an ASP. NET application in the IDE
Will result in the error "unable to attach to ASP. NET worker

The example worldtravel (webdb) requires interbase7.1 (http://www.interbase.com), with "localhost: C:/program files/Borland/bds/2.0/demos/webdb/worldtravel. GDB" set bdpconnection. Test passed.

Example dB/aspportal
1. Restore database d4netsoft (mssql2k) from owebackup. Bak. Note that the location of database files must be specified on disk C;
2. Copy the directory bdswebexample to the wwwroot of IIS and rename it octanewebexample.

Accessing an ASP. NET "helloworld" Web Services Application encountered the following problem:
Procedure twinform1.button1 _ click (Sender: system. object; E: system. eventargs );
Begin
New WS: = webservice1 ();
Button1.text: = ws. helloworld ();
End;
The following error occurs during compilation:

If it doesn't work, modify it by yourself and add the following line to the Code:
Uses localhost1.webservice1;
Then modify the Code as follows:
Procedure twinform1.button1 _ click (Sender: system. object; E: system. eventargs );
VaR WS: localhost1.webservice1. twebservice1;
Begin
WS: = localhost1.webservice1. twebservice1.create ();
Button1.text: = ws. helloworld ();
End;
Compiled successfully.

Both clients have tried. Successful!
The WebService under Tomcat written in jbuilder9 is tested by a client written in delphi8.

Delphi8 provides a new database technology ADO. net and BDP. net, including BDE for backward compatibility, dbexpress for creating cross-platform applications, ibx. net (Interbase. net), datasnap.. net.

Two different applications can be created in delphi8. VCL Forms Application and Windows Forms Application also have. Net VCL Component and. NET component .. Net VCL component is designed to be compatible with previous versions. Ado. Net connector is such a control, but it cannot be found in the toolbar. Many controls do not appear, including many Active X controls.

When developing ASP. NET applications using delphi8, the server-side scripting language also uses C #.

2004/01/12
General steps for developing ASP. NET Applications with delphi8:
1. Establish bdpconnection
2. Create bdpdataadapter, set connection in bdpdataadapter, select table, and select Dataset
3. Set tables-columns in Dataset
4. Create dbwebdatasource
5. Create dbwebgrid and dbwebnavigator, set their dbdatasource and tablename, and set columns of dbwebgrid (which can include button column, edit, delete, etc)

The following error occurs in Asp.net created by delphi.net: "unable to attch to Asp.net worker process (typically aspnet_wp.exe or w3wp.exe )"
This error is generally caused by the installation of IIS only after the. NET Framework is installed. The solution is to execute the following command in the command line
% Comspec %/K % WINDIR %/microsoft.net/framework/v1.1.4322/aspnet_regiis.exe-I
This error may occur again later. Just try again.
In this way, a sub-directory aspnet_client will be created under the directory of the web site.

Yesterday, vs. Net was installed, and the "Hello World" example of Web Service was tried. This method is very similar to delphi8. Debugging is not supported. Check and solve the problem according to the online help. Replace the IP address with the computer name.

2004/01/07
Press online help to use vs. Net for Web pages. Click a button to bring up a message box, which is very convenient. C # can replace JScript.

2004/07/12
Download the IBM Rational xde developer. Net evaluation version (valid for 15 days), which is closely integrated with vs.net.

I recently started learning Delphi again. I stopped for several years. I looked for some information and found it. I don't have time to read it. I installed it here first, and I will read it later. I saw Li Wei's D8 video lecture last night. I found that D8 is just like. Borland approached. net. Is it the same way ?! However, we are still happy to see features like D8.
