• Com server build using Python on 64-bit Windows 7 machine

  - by Vijayendra Bapte

  Original post is here: http://mail.python.org/pipermail/python-win32/2010-December/011011.html I am using: OS: 64 bit Windows 7 Professional Python: python-2.7.1.amd64 Python win32 extensions: pywin32-214.win-amd64-py2.7 Py2exe: py2exe-0.6.9.win64-py2.7.amd64 I am trying to build icon overlay for Windows. It has worked fine on 32 bit Windows but not working on 64 bit Windows 7. Here are the Python modules I have created for testing: test_icon_overlay.py: ( http://mail.python.org/pipermail/python-win32/attachments/20101229/bb8c78a4/attachment-0002.obj ) com server created in Python for icon overlay which adds check mark overlay icon(C:\icons\test.ico) on "C:\icons" folder setup_VI.py: ( http://mail.python.org/pipermail/python-win32/attachments/20101229/bb8c78a4/attachment-0003.obj ) setup file which creates test_icon_overlay.dll for distribution. icons.zip: ( http://mail.python.org/pipermail/python-win32/attachments/20101229/bb8c78a4/attachment-0001.zip ) for testing you should extract icons.zip inside C:\ Icon overlay appears on C:\icons folder when I execute python test_icon_overlay.py on Windows command prompt and restarts explorer.exe. But its not working with the dll file created using setup_VI.py I have created dll file using python setup_VI.py py2exe and then tried to register it using regsvr32 test_icon_overlay.dll. Registration fails with windows error message Error 0x80040201 while registering shell extension. Then I turned on logger in Python27/Lib/site-packages/py2exe/boot_com_servers.py and here is the traceback which I am getting in comerror.txt on regsvr32 test_icon_overlay.dll PATH is ['C:\\root\\avalon\\module\\sync\\python\\src\\dist\\library.zip'] Traceback (most recent call last): File "boot_com_servers.py", line 37, in <module> pywintypes.error: (126, 'GetModuleFileName', 'The specified module could not be found.') Traceback (most recent call last): File "<string>", line 1, in <module> NameError: name 'DllRegisterServer' is not defined Looks like there might be a problem with win32api.GetModuleFileName(sys.frozendllhandle) or with the dll build on 64-bit Windows 7. Also, I saw that installation of pywin32-214.win-amd64-py2.7 on 64-bit Windows 7 finish with the error message: Snapshot close failed in file object destructor: sys.excepthook is missing lost sys.stderr Is there anything which I am doing wrong? Any help on this is highly appreciated.

• How to connect to a queue manager with ssl enabled server connection channel when authentication is

  - by Dr. Xray

  I am trying to write a java application connecting to server connection channel with SSL enabled. So far, I have been successfully connected to the channel by setting authentication to 'optional'. However, when I set it to be 'required', the connection fails. Here is what I did: Create key db for queue manager and keystore for the java client user. Create key/self-signed certificates for the queue manager and the client user, with names prefixed ibmwebspheremq. Export, exchange and import certificates for the queue manager and the client. (I did answered 'yes' when being asked whether I trust the queue manager cert). The location and password to the truststore and keystore are set to point to the same keystore at the client side, where the orgininal created client user key and the imported queue manager key are. With other settings being the same, if I switch back to 'optional' authentication, the connection works. I think there is something I understand incorrectly about this ssl authenticaion but cannot figure out what. Could someone kindly help me?

• Trying to use a authlogic-connect as a plugin in place of gem - Server doesn't start

  - by Arkid

  I am trying to use Authlogic-connect as a plugin in Rails 3 in place of a gem. I have made an entry in the gemfile as gem "authlogic-connect", :require => "authlogic-connect", :path => "localgems" Now when I run the bundle install, it runs fine. When I try to start the server i get the error Could not find gem 'authlogic-connect (>= 0, runtime)' in source at localgems. Source does not contain any versions of 'authlogic-connect (>= 0, runtime)' Try running `bundle install`. I have placed the unzipped Gem renamed as authlogic-connect in the localgems folder. what is the problem? Here is what I get on using rails plugin install arkidmitra$ rails plugin install git://github.com/viatropos/authlogic-connect.git Usage: rails new APP_PATH [options] Options: [--skip-gemfile] # Don't create a Gemfile -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db) # Default: sqlite3 -O, [--skip-active-record] # Skip Active Record files [--dev] # Setup the application with Gemfile pointing to your Rails checkout -J, [--skip-prototype] # Skip Prototype files -T, [--skip-test-unit] # Skip Test::Unit files -G, [--skip-git] # Skip Git ignores and keeps -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) -b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) [--edge] # Setup the application with Gemfile pointing to Rails repository Runtime options: -q, [--quiet] # Supress status output -s, [--skip] # Skip files that already exist -f, [--force] # Overwrite files that already exist -p, [--pretend] # Run but do not make any changes Rails options: -h, [--help] # Show this help message and quit -v, [--version] # Show Rails version number and quit Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify.

• pylons on production server fedora 8

  - by stormdrain

  I'm interested in learning some python, and thought Pylons would be a good starting point (after spending 2 days trying to get django working -- to no avail). I have an Amazon EC2 instance with Fedora 8 on it. It is a bare-bones install. I am halfway through my second day of trying to get it to work. I have mod_wsgi installed. I have Apache (though that's a later task to tackle). I have easy_install, paster is working fine; basically all of the pre-requisites mentioned throughout the Pylons docs. I can't for the life of me get the thing to work. And I can't seem to find a coherent walkthough anywhere that lists all the steps necessary. There is tons of info out there, but it is all scattered. Wsgi this, python that. Google, google, google... "47 million results found for 'socket.error:(lol, 'Yous a goofs')". So, this is my latest attempt: apachectl -k stop cd /home/ paster create -t pylons test [blah blah.. ok] cd test nano development.ini [hmm, last time I changed the host from 127.0.0.1 to my domain name or url, it threw an error like socket.error: (99, 'Cannot assign requested address')... I'll just leave it] [open port 5000 on firewall] paster serve development.ini [firefox-url:5000] Firefox can't establish a connection to the server Doing these steps locally works as expected. This is just a test to see if I can get it to work at all, which I can't. If I get it to work, then is the task of getting it to work with apache. My madness is that I'd like to play around a little developing and deploying before diving into a full-fledged project. So far: self, I am dissapoint.

• JQUERY, AutoSuggest that doesn't kill the Server on ever keyup

  - by nobosh

  I'm working to build a JQUERY enabled AutoSuggest plugin, inspired by Apple's spotlight. Here is the general code: $(document).ready(function() { $('#q').bind('keyup', function() { if( $(this).val().length == 0) { // Hide the q-suggestions box $('#q-suggestions').fadeOut(); } else { // Show the AJAX Spinner $("#q").css("background-image","url(/images/ajax-loader.gif)"); $.ajax({ url: '/search/spotlight/', data: {"q": $(this).val()}, success: function(data) { $('#q-suggestions').fadeIn(); // Show the q-suggestions box $('#q-suggestions').html(data); // Fill the q-suggestions box // Hide the AJAX Spinner $("#q").css("background-image","url(/images/icon-search.gif)"); } }); } }); The issue I want to solve well & elegantly, is not killing the sever. Right now the code above hits the server every time you type a key and does not wait for you to essentially finish typing. What's the best way to solve this? A. Kill previous AJAX request? B. Some type of AJAX caching? C. Adding some type of delay to only submit .AJAX() when the person has stopped typing for 300ms or so? Thanks

• Configure IIS7 to server static content through ASP.NET Runtime

  - by Anton Gogolev

  I searched high an low and still cannot find a definite answer. How do I configure IIS 7.0 or a Web Application in IIS so that ASP.NET Runtime will handle all requests -- including ones to static files like *.js, *.gif, etc? What I'm trying to do is as follows. We have kind of SaaSy site, which we can "skin" for every customer. "Skinnig" means developing a custom master page and using a bunch of *.css and other images. Quite naturally, I'm using VirtualPathProvider, which operates like this: public override System.Web.Hosting.VirtualFile GetFile(string virtualPath) { if(PhysicalFileExists(virtualPath)) { var virtualFile = base.GetFile(virtualPath); return virtualFile; } if(VirtualFileExists(virtualPath)) { var brandedVirtualPath = GetBrandedVirtualPath(virtualPath); var absolutePath = HttpContext.Current.Server.MapPath(brandedVirtualPath); Trace.WriteLine(string.Format("Serving '{0}' from '{1}'", brandedVirtualPath, absolutePath), "BrandingAwareVirtualPathProvider"); var virtualFile = new VirtualFile(brandedVirtualPath, absolutePath); return virtualFile; } return null; } The basic idea is as follows: we have a branding folder inside our webapp, which in turn contains folders for each "brand", with "brand" being equal to host name. That is, requests to http://foo.example.com/ should use static files from branding/foo_example_com, whereas http://bar.example.com/ should use content from branding/bar_example_com. Now what I want IIS to do is to forward all requests to static files to StaticFileHandler, which would then use this whole "infrastructure" and serve correct files. However, try as I might, I cannot configure IIS to do this.

• Problems running Ruby on Rails apps on shared hosted server

  - by Evgeny

  I have problems installing any Ruby On Rails app on my shared hosted server. Mongrel shows html as plain text for all pages. The problem occurs for any app, even if I create a test empty app and add a scaffolded view without changing anything. It appears that the Mongrel crashes when trying to put cookies to the response header. The HTTP header looks incomplete, the Content-type and other parameters are missing: curl 127.0.0.1:12002/users -I HTTP/1.1 200 OK Connection: close Date: Wed, 26 May 2010 09:46:50 GMT Content-Length: 0 Here is the output from mongrel.log Error calling Dispatcher.dispatch #<NoMethodError: You have a nil object when you didn't expect it!

• Lightweight development web server with support for PHP v2

  - by David

  In line with this question: http://stackoverflow.com/questions/171655/lightweight-web-app-server-for-php The above question has been asked numerous times and answered exactly the same in all the cases I've found using google. My question is similar to a degree but with a different desired goal: On demand development instances. I have come up with a somewhat questionable solution to host arbitrary directories in my user account for the purpose of development testing. I am not interested in custom vhosts but looking to emulate the behaviour I get when using paster or mongrel for Python & Ruby respectively. Ubuntu 9.10 TOXIC@~/ APACHE_RUN_USER=$USER APACHE_RUN_GROUP=www-data apache2 -d ~/Desktop/ -c "Listen 2990" Is there a better solution, could I do something similar with nginix or lighttpd? Note: The above won't work correctly for stock environments without a copied & altered httpd.conf. Update: The ideal goal is to mimic Paster, Webbrick, and Mongrel for rapid local development hosting. For those light weight servers, it takes less then a minute to get a working instance running ( not factoring any DB support ). Apache2 vhost is great but I've been using Apache2 for over ten years and it would be some sort of abomination hack to setup a new entry in /etc/hosts unless you have your own DNS, in which case a wildcard subdomain setup would probably work great. EXCEPT one more problem, it's pretty easy for me to know what is being hosted ( ex. by paster or mongeral ) just doing a sudo netstat -tulpn while there would be a good possibility of confusion in figure out which vhost is what.

• Need help choosing database server

  - by The Pretender

  Good day everyone. Recently I was given a task to develop an application to automate some aspects of stocks trading. While working on initial architecture, the database dilemma emerged. What I need is a fast database engine which can process huge amounts of data coming in very fast. I'm fairly experienced in general programming, but I never faced a task of developing a high-load database architecture. I developed a simple MSSQL database schema with several many-to-many relationships during one of my projects, but that's it. What I'm looking for is some advice on choosing the most suitable database engine and some pointers to various manuals or books which describe high-load database development. Specifics of the project are as follows: OS: Windows NT family (Server 2008 / 7) Primary platform: .NET with C# Database structure: one table to hold primary items and two or three tables with foreign keys to the first table to hold additional information. Database SELECT requirements: Need super-fast selection by foreign keys and by combination of foreign key and one of the columns (presumably DATETIME) Database INSERT requirements: The faster the better :) If there'll be significant performance gain, some parts can be written in C++ with managed interfaces to the rest of the system. So once again: given all that stuff I just typed, please give me some advice on what the best database for my project is. Links or references to some manuals and books on the subject are also greatly appreciated. EDIT: I'll need to insert 3-5 rows in 2 tables approximately once in 30-50 milliseconds and I'll need to do SELECT with 0-2 WHERE clauses queries with similar rate.

• Jsp page getting called from cache rather than getting loaded from server

  - by sam4u-optimistic86

  I am calling a jsp based on 2 parameters which is passed from jsp 1 in this way.Below i pass 2 parameters into 2.jsp and based on these 2 parameters data is displayed in 2.jsp.I have a loop in which i have a number of hrefs like the one i have described below.Each of these href passes a different set of value to 2.jsp. out.println("<a href=\"2.jsp?prId=" + prog.getId() + count + "\">" + prog.getName() + "</a>"); I retrieve these 2 parameters in 2.jsp using the following lines count_id = request.getParameter( "country_id" ); prog_id = Integer.parseInt(request.getParameter( "program_id" )); Based on these 2 parameters i show the corresponding data in 2.jsp Now i have a back button in 2.jsp and i call 1.jsp in 2.jsp using the following code <a href="1.jsp"><img src="/image/back.gif" border="0"></a> The problem is when i use the back button and go back to 1.jsp and select another href like the one i have described above i get the data related to the previous href selected. I guess the problem is when i request the page is loaded from cache rather than from the server. Please advice

• Calling webservice via server causes java.net.MalformedURLException: no protocol

  - by Thomas

  I am writing a web-service, which parses an xml file. In the client, I read the whole content of the xml into a String then I give it to the web-service. If I run my web-service with main as a Java-Application (for tests) there is no problem, no error messages. However when I try to call it via the server, I get the following error: java.net.MalformedURLException: no protocol I use the same xml file, the same code (without main), and I just cannot figure out, what the cause of the error can be. here is my code: DOMParser parser=new DOMParser(); try { parser.setFeature("http://xml.org/sax/features/validation", true); parser.setFeature("http://apache.org/xml/features/validation/schema",true); parser.setFeature("http://apache.org/xml/features/validation/dynamic",true); parser.setErrorHandler(new myErrorHandler()); parser.parse(new InputSource(new StringReader(xmlFile))); document=parser.getDocument(); xmlFile is constructed in the client so: String myFile ="C:/test.xml"; File file=new File(myFile); String myString=""; FileInputStream fis=new FileInputStream(file); BufferedInputStream bis=new BufferedInputStream(fis); DataInputStream dis=new DataInputStream(bis); while (dis.available()!=0) { myString=myString+dis.readLine(); } fis.close(); bis.close(); dis.close(); Any suggestions will be appreciated!

  I'm trying to close my UDT server (Netty 4.0.5.Final) with shutDownGracefully() and reopen it on the same port. Unfortunately, I always get the socket exception below although it waits until the future has completed. I also added the socket option SO_REUSEADDR. What is the proper way to do this? Exception in thread "main" com.barchart.udt.ExceptionUDT: UDT Error : 5011 : another socket is already listening on the same UDP port : listen0:listen [id: 0x323d3939] at com.barchart.udt.SocketUDT.listen0(Native Method) at com.barchart.udt.SocketUDT.listen(SocketUDT.java:1136) at com.barchart.udt.net.NetServerSocketUDT.bind(NetServerSocketUDT.java:66) at io.netty.channel.udt.nio.NioUdtAcceptorChannel.doBind(NioUdtAcceptorChannel.java:71) at io.netty.channel.AbstractChannel$AbstractUnsafe.bind(AbstractChannel.java:471) at io.netty.channel.DefaultChannelPipeline$HeadHandler.bind(DefaultChannelPipeline.java:1006) at io.netty.channel.DefaultChannelHandlerContext.invokeBind(DefaultChannelHandlerContext.java:504) at io.netty.channel.DefaultChannelHandlerContext.bind(DefaultChannelHandlerContext.java:487) at io.netty.channel.ChannelDuplexHandler.bind(ChannelDuplexHandler.java:38) at io.netty.handler.logging.LoggingHandler.bind(LoggingHandler.java:254) at io.netty.channel.DefaultChannelHandlerContext.invokeBind(DefaultChannelHandlerContext.java:504) at io.netty.channel.DefaultChannelHandlerContext.bind(DefaultChannelHandlerContext.java:487) at io.netty.channel.DefaultChannelPipeline.bind(DefaultChannelPipeline.java:848) at io.netty.channel.AbstractChannel.bind(AbstractChannel.java:193) at io.netty.bootstrap.AbstractBootstrap$2.run(AbstractBootstrap.java:321) at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:354) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:366) at io.netty.util.concurrent.SingleThreadEventExecutor$2.run(SingleThreadEventExecutor.java:101) at java.lang.Thread.run(Thread.java:724) A small test program demonstration the problem: public class MsgEchoServer { public static class MsgEchoServerHandler extends ChannelInboundHandlerAdapter { } public void run() throws Exception { final ThreadFactory acceptFactory = new UtilThreadFactory("accept"); final ThreadFactory connectFactory = new UtilThreadFactory("connect"); final NioEventLoopGroup acceptGroup = new NioEventLoopGroup(1, acceptFactory, NioUdtProvider.MESSAGE_PROVIDER); final NioEventLoopGroup connectGroup = new NioEventLoopGroup(1, connectFactory, NioUdtProvider.MESSAGE_PROVIDER); try { final ServerBootstrap boot = new ServerBootstrap(); boot.group(acceptGroup, connectGroup) .channelFactory(NioUdtProvider.MESSAGE_ACCEPTOR) .option(ChannelOption.SO_BACKLOG, 10) .option(ChannelOption.SO_REUSEADDR, true) .handler(new LoggingHandler(LogLevel.INFO)) .childHandler(new ChannelInitializer<UdtChannel>() { @Override public void initChannel(final UdtChannel ch) throws Exception { ch.pipeline().addLast(new MsgEchoServerHandler()); } }); final ChannelFuture future = boot.bind(1234).sync(); } finally { acceptGroup.shutdownGracefully().syncUninterruptibly(); connectGroup.shutdownGracefully().syncUninterruptibly(); } new MsgEchoServer().run(); } public static void main(final String[] args) throws Exception { new MsgEchoServer().run(); } }

• Error // Usage: rails new APP_PATH [options] // when running 'rails server'

  - by madphill

  Background info: I'm using GIT to get a repository of a project with Ruby files in it. The project lives in my SITES folder under home directory on my Mac. I have Ruby: 1.8.7 I have just upgraded Rails to: 3.0.3 All I am trying to accomplish is to be able to render localhost.com:3000 in my browser of the GIT project i've already downloaded so I can work on it locally. I ran the command 'rails server' and was returned the message below:: Usage: rails new APP_PATH [options] Options: [--skip-gemfile] # Don't create a Gemfile -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db) # Default: sqlite3 -O, [--skip-active-record] # Skip Active Record files -J, [--skip-prototype] # Skip Prototype files -T, [--skip-test-unit] # Skip Test::Unit files [--dev] # Setup the application with Gemfile pointing to your Rails checkout -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -G, [--skip-git] # Skip Git ignores and keeps -b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) [--edge] # Setup the application with Gemfile pointing to Rails repository Runtime options: -f, [--force] # Overwrite files that already exist -s, [--skip] # Skip files that already exist -p, [--pretend] # Run but do not make any changes -q, [--quiet] # Supress status output Rails options: -h, [--help] # Show this help message and quit -v, [--version] # Show Rails version number and quit Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify. Example: rails new ~/Code/Ruby/weblog This generates a skeletal Rails installation in ~/Code/Ruby/weblog. See the README in the newly created application to get going.

• Uploading UIImage to server using UIImageJPEGRepresentation

  - by Thomas Joos

  hi all, I'm writing an app which uploads a UIImage to my server. This works perfect, as I see the pictures being added. I use the UIImageJPEGRepresentation for the image data and configure an NSMutableRequest. ( setting url, http method, boundary, content types and parameters ) I want to display an UIAlertView when the file is being uploaded and I wrote this code: //now lets make the connection to the web NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(@"return info: %@", returnString); if (returnString == @"OK") { NSLog(@"you are snapped!"); // Show message image successfully saved UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"You are snapped!" message:@"BBC snapped your picture and will send it to your email adress!" delegate:self cancelButtonTitle:@"OK!" otherButtonTitles:nil]; [alert show]; [alert release]; } [returnString release]; The returnString outputs: 2010-04-22 09:49:56.226 bbc_iwh_v1[558:207] return info: OK The problem is that my if statements does not say returnstring == @"OK" as I don't get the AlertView. How should I check this returnstring value?

• php file path of server

  - by Jacksta

  I am trying to get this script to work. it opens up a directry and lists the files in the directory. I have copied this code from somewhere else and the problem is that this php file is hosted on an apache server not my localhost. what is the correct $dir_name = "c:/"; to use? The file is in this directory /domains/domainxxxx.com.au/public_html/lsitfiles.php so would I use domainxxxx.com.au/public_html/lsitfiles.php ? <?php $dir_name = "c:/"; $dir = opendir($dir_name); $file_list = "<ul>"; while ($file_name = readdir($dir)) { if(($file_name != ".") && (file_name != "..")) { $file_list .= "<li>$file_name"; } } $file_list.= "<ul>"; closedir($dir); ?> <HTML> <BODY> <p>Files in: <? echo "$dir_name"; ?></p> <? echo "$file_list"; ?> </BODY> </HTML>

• The following code to check if a file exists on a server does not work

  - by xplorer2k

  Hi Everyone, I found the following code to check if a file exists on a server, but is not working for me. It tells me that "test1.tx" does not exist even though the file exists and its size is 498 bytes. If I try with Ftp.ListDirectory it tells me that the file does not exist. If I try with Ftp.GetFileSize it does not provide any results and the debugger's immediate gives me the following message: A first chance exception of type 'System.Net.WebException' occurred in System.dll. Using "request.UseBinary = true" does not make any difference. I have posted this same question at this link: http://social.msdn.microsoft.com/Forums/en-US/ncl/thread/89e05cf3-189f-48b7-ba28-f93b1a9d44ae Could someone help me how to fix it? private void button1_Click(object sender, EventArgs e) { string ftpServerIP = txtIPaddress.Text.Trim(); string ftpUserID = txtUsername.Text.Trim(); string ftpPassword = txtPassword.Text.Trim(); try { FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + ftpServerIP + "//tmp/test1.txt"); request.Method = WebRequestMethods.Ftp.ListDirectory; //request.Method = WebRequestMethods.Ftp.GetFileSize; request.Credentials = new NetworkCredential(ftpUserID, ftpPassword); //request.UseBinary = true; using (FtpWebResponse response = (FtpWebResponse)request.GetResponse()) { // Okay. textBox1.AppendText(Environment.NewLine); textBox1.AppendText("File exist"); } } catch (WebException ex) { if (ex.Response != null) { FtpWebResponse response = (FtpWebResponse)ex.Response; if (response.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable) { // Directory not found. textBox1.AppendText(Environment.NewLine); textBox1.AppendText("File does not exist"); } } } } Thanks very much, xplorer2k

• Connecting to MS SQL Server 2005 via Web Service

  - by clear-cycle-corp

  Delphi 2010, dbExpress, and MS SQL Server 2005 DB Ok, I am trying to make a connection to a MS SQL 2005 DB using Delphi 2010 & DBExpress. If I create a standard delphi application and hard code my connection (IT WORKS!): procedure TForm1.Button1Click(Sender: TObject); var Conn: TSQLConnection; begin Conn:= TSQLConnection.Create(nil); Conn.ConnectionName:= 'VPUCDS_VPN_SE01'; Conn.LoadParamsOnConnect := True; Conn.LoginPrompt:=True; try Conn.Connected:= True; if Conn.Connected then ShowMessage('Connected!') else ShowMessage('NOT Connected!') finally Conn.Free; end; end; All the ini files, and DLLs reside in the same folder as my executable and yes, I have DBXMsSQL & MidasLib in the uses clause again, it works if its not a web service! However, if i then move the code over to a Web serices CGI module: function TTest.ConnectToDB: Boolean;stdcall; var Conn: TSQLConnection; begin Conn:= TSQLConnection.Create(nil); Conn.ConnectionName:= 'VPUCDS_VPN_SE01'; Conn.LoadParamsOnConnect := True; Conn.LoginPrompt:=True; try Conn.Connected:= True; result:= Conn.Connected; finally Conn.Free; end; end; Thanks
