  • How to Determine the Size of MSADO Command Parameters

    - by Adam
    I am new to MS ADO and trying to understand how to set the size on command parameters as created by the command.CreateParameter (Name, Type, Direction, Size, Value) The documentation says the following: Size Optional. A Long value that specifies the maximum length for the parameter value in characters or bytes. ... If you specify a variable-length data type in the Type argument, you must either pass a Size argument or set the Size property of the Parameter object before appending it to the Parameters collection; otherwise, an error occurs. 1.) What should one pass for fixed-size parameters? Is it a "don't care"? I was a bit confused by the example found here, in which they set size to 3 for an adInteger parameter with Value set to a variant of type VT_I2 pPrmByRoyalty->Type = adInteger; pPrmByRoyalty->Size = 3; pPrmByRoyalty->Direction = adParamInput; pPrmByRoyalty->Value = vtroyal; VT_I2 implies two bytes. A tagVARIANT struct is 16 bytes. How did they land on three? I see that the enum value for adInteger happens to be three, but I suspect that is just a coincidence. So it's a bit confusing what to pass for fixed-size parameters. The team I'm working with has always passed sizeof(int) for adInteger, and it seems to work. Is that correct? Now, for "variable-length" parameters: we are instructed by the documentation to pass "the maximum length .. in characters or bytes". 2.) For adVarChar, is it sufficient to pass the max width as defined in the database? 3.) What about the Wide types (e.g. adVarWChar)? Is it characters or bytes? 4.) How about adVariant, which could contain fixed- or variable-length data? 5.) Do arrays ever come into play here? (we don't pass them as parameters, just curious) Any references or personal insights are welcome.

  • Succinct introduction to C++/CLI for C#/Haskell/F#/JS/C++/... programmer

    - by Henrik
    Hello everybody, I'm trying to write integrations with the operating system and with things like active directory and Ocropus. I know a bunch of programming languages, including those listed in the title. I'm trying to learn exactly how C++/CLI works, but can't find succinct, exact and accurate descriptions online from the searching that I have done. So I ask here. Could you tell me the pitfalls and features of C++/CLI? Assume I know all of C# and start from there. I'm not an expert in C++, so some of my questions' answers might be "just like C++", but could say that I am at C#. I would like to know things like: Converting C++ pointers to CLI pointers, Any differences in passing by value/doubly indirect pointers/CLI pointers from C#/C++ and what is 'recommended'. How do gcnew, __gc, __nogc work with Polymorphism Structs Inner classes Interfaces The "fixed" keyword; does that exist? Compiling DLLs loaded into the kernel with C++/CLI possible? Loaded as device drivers? Invoked by the kernel? What does this mean anyway (i.e. to load something into the kernel exactly; how do I know if it is?)? L"my string" versus "my string"? wchar_t? How many types of chars are there? Are we safe in treating chars as uint32s or what should one treat them as to guarantee language indifference in code? Finalizers (~ClassName() {}) are discouraged in C# because there are no garantuees they will run deterministically, but since in C++ I have to use "delete" or use copy-c'tors as to stack allocate memory, what are the recommendations between C#/C++ interactions? What are the pitfalls when using reflection in C++/CLI? How well does C++/CLI work with the IDisposable pattern and with SafeHandle, SafeHandleZeroOrMinusOneIsInvalid? I've read briefly about asynchronous exceptions when doing DMA-operations, what are these? Are there limitations you impose upon yourself when using C++ with CLI integration rather than just doing plain C++? Attributes in C++ similar to Attributes in C#? Can I use the full meta-programming patterns available in C++ through templates now and still have it compile like ordinary C++? Have you tried writing C++/CLI with boost? What are the optimal ways of interfacing the boost library with C++/CLI; can you give me an example of passing a lambda expression to an iterator/foldr function? What is the preferred way of exception handling? Can C++/CLI catch managed exceptions now? How well does dynamic IL generation work with C++/CLI? Does it run on Mono? Any other things I ought to know about?

  • How do I use connect to DB2 with DBI and mod_perl?

    - by Matthew
    I'm having issues with getting DBI's IBM DB2 driver to work with mod_perl. My test script is: #!/usr/bin/perl use strict; use CGI; use Data::Dumper; use DBI; { my $q; my $dsn; my $username; my $password; my $sth; my $dbc; my $row; $q = CGI->new; print $q->header; print $q->start_html(); $dsn = "DBI:DB2:SAMPLE"; $username = "username"; $password = "password"; print "<pre>".$q->escapeHTML(Dumper(\%ENV))."</pre>"; $dbc = DBI->connect($dsn, $username, $password); $sth = $dbc->prepare("SELECT * FROM SOME_TABLE WHERE FIELD='SOMETHING'"); $sth->execute(); $row = $sth->fetchrow_hashref(); print "<pre>".$q->escapeHTML(Dumper($row))."</pre>"; print $q->end_html; } This script works as CGI but not under mod_perl. I get this error in apache's error log: DBD::DB2::dr connect warning: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /usr/lib/perl5/site_perl/5.8.8/Apache/DBI.pm line 190. DBI connect('SAMPLE','username',...) failed: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /data/www/perl/test.pl line 15 First of all, why is it using ODBC? The native DB2 driver is installed (hence it works as CGI). Running Apache 2.2.3, mod_perl 2.0.4 under RHEL5. This guy had the same problem as me: http://www.mail-archive.com/[email protected]/msg22909.html But I have no idea how he fixed it. What does mod_php4 have to do with mod_perl? Any help would be greatly appreciated, I'm having no luck with google. Update: As james2vegas pointed out, the problem has something to do with PHP: I disable PHP all together I get the a different error: Total Environment allocation failure! Did you set up your DB2 client environment? I believe this error is to do with environment variables not being set up correctly, namely DB2INSTANCE. However, I'm not able to turn off PHP to resolve this problem (I need it for some legacy applications). So I now have 2 questions: How can I fix the original issue without disabling PHP all together? How can I fix the environment issue? I've set DB2INSTANCE, DB2_PATH and SQLLIB variables correctly using SetEnv and PerlSetEnv in httpd.conf, but with no luck. Note: I've edited the code to determine if the problem was to do with Global Variable Persistence.

  • Mixing policy-based design with CRTP in C++

    - by Eitan
    I'm attempting to write a policy-based host class (i.e., a class that inherits from its template class), with a twist, where the policy class is also templated by the host class, so that it can access its types. One example where this might be useful is where a policy (used like a mixin, really), augments the host class with a polymorphic clone() method. Here's a minimal example of what I'm trying to do: template <template <class> class P> struct Host : public P<Host<P> > { typedef P<Host<P> > Base; typedef Host* HostPtr; Host(const Base& p) : Base(p) {} }; template <class H> struct Policy { typedef typename H::HostPtr Hptr; Hptr clone() const { return Hptr(new H((Hptr)this)); } }; Policy<Host<Policy> > p; Host<Policy> h(p); int main() { return 0; } This, unfortunately, fails to compile, in what seems to me like circular type dependency: try.cpp: In instantiation of ‘Host<Policy>’: try.cpp:10: instantiated from ‘Policy<Host<Policy> >’ try.cpp:16: instantiated from here try.cpp:2: error: invalid use of incomplete type ‘struct Policy<Host<Policy> >’ try.cpp:9: error: declaration of ‘struct Policy<Host<Policy> >’ try.cpp: In constructor ‘Host<P>::Host(const P<Host<P> >&) [with P = Policy]’: try.cpp:17: instantiated from here try.cpp:5: error: type ‘Policy<Host<Policy> >’ is not a direct base of ‘Host<Policy>’ If anyone can spot an obvious mistake, or has successfuly mixing CRTP in policies, I would appreciate any help.

  • Need to set cursor position to the end of a contentEditable div, issue with selection and range obje

    - by DavidR
    I'm forgetting about cross-browser compatibility for the moment, I just want this to work. What I'm doing is trying to modify a script (and you probably don't need to know this) located at typegreek.com The basic script is found here. Basically what it does is when you type in characters, it converts the character your are typing into greek characters and prints it onto the screen. What I'm trying to do is to get it to work on contentEditable div's (It only works for Textareas) My issue is with this one function: The user types a key, it get's converted to a greek key, and goes to a function, it gets sorted through some if's, and where it ends up is where I can add div support. Here is what I have so far, myField is the div, myValue is the greek character. //Get selection object... var userSelection if (window.getSelection) {userSelection = window.getSelection();} else if (document.selection) {userSelection = document.selection.createRange();} //Now get the cursor position information... var startPos = userSelection.anchorOffset; var endPos = userSelection.focusOffset; var cursorPos = endPos; //Needed later when reinserting the cursor... var rangeObj = userSelection.getRangeAt(0) var container = rangeObj.startContainer //Now take the content from pos 0 -> cursor, add in myValue, then insert everything after myValue to the end of the line. myField.textContent = myField.textContent.substring(0, startPos) + myValue + myField.textContent.substring(endPos, myField.textContent.length); //Now the issue is, this updates the string, and returns the cursor to the beginning of the div. //so that at the next keypress, the character is inserted into the beginning of the div. //So we need to reinsert the cursor where it was. //Re-evaluate the cursor position, taking into account the added character. var cursorPos = endPos + myValue.length; //Set the caracter position. rangeObj.setStart(container,cursorPos) Now, this works only as long as I don't type more than the size of the original text. Say I had 30 characters in the div before hand. If I type more than that 30, it adds character 31, but places the cursor back at 30. I can type character 32 at pos.31, then character 33 at pos.32, but if I try to put character 34 in, it adds the character, and sets the cursor back at 32. The issue is that the function for adding the new character screws up if cursorPos is greater than what is defined in the range. Any ideas?

  • Unicast traffic between hosts on a switch leaving the switch by its uplink. Why?

    - by Rich Lafferty
    I have a weird thing happening on our network at my office which I can't quite get my head around. In particular I can't tell if it's a problem with a switch, or a problem with configuration. We have a Cisco SG300-52 switch (sw01) in the top of a rack in our server room, connected to another SG300-28 that acts as our core switch (core01). Both run layer 2 only, our firewalls do routing between VLANs. They have a dozen or so VLANs between them. Gi1 on sw01 is a trunk port connected to gi1 on core01. (Disclosure: There are other switches in our environment but I'm pretty sure I've isolated the problem down to these two. Happy to provide more info if necessary.) The behaviour I'm seeing is limited to one VLAN, vlan 12 -- or, at least, it's not happening on the other ones I checked (It's hard to guarantee the absence of packets), and it is: sw01 is forwarding, to core01, traffic which is between two hosts which are both plugged into sw01. (I noticed this because the IDS in our firewall gave a false positive on traffic which should not reach the firewall.) We noticed this mostly between our two dhcp/dns servers, net01 (10.12.0.10) and net02 (10.12.0.11). net01 is physical hardware and net02 is on a VMware ESX server. net01 is connected to gi44 on sw01 and net02's ESX server to gi11. [net01]----gi44-[sw01]-gi1----gi1-[core01] [net02]----gi11/ Let's see some interfaces! Remember, vlan 12 is the problem vlan. Of the others I explicitly verified that vlan 27 was not affected. Here's the two hosts' ports: esx01 contains net02. sw01#sh run int gi11 interface gigabitethernet11 description esx01 lldp med disable switchport trunk allowed vlan add 5-7,11-13,100 switchport trunk native vlan 27 ! sw01#sh run int gi44 interface gigabitethernet44 description net01-1 lldp med disable switchport mode access switchport access vlan 12 ! Here's the trunk on sw01. sw01#sh run int gi1 interface gigabitethernet1 description "trunk to core01" lldp med disable switchport trunk allowed vlan add 4-7,11-13,27,100 ! And the other end of the trunk on core01. interface gigabitethernet1 description sw01 macro description switch switchport trunk allowed vlan add 2-7,11-16,27,100 ! I have a monitor port on core01, thus: core01#sh run int gi12 interface gigabitethernet12 description "monitor port" port monitor GigabitEthernet 1 ! And the monitor port on core01 sees unicast traffic going between net01 and net02, both of which are on sw01! I've verified this with a monitor port on sw01 that sees the net01-net02 unicast traffic leaving via gi1 too. sw01 knows that both of those hosts are on ports that are not its trunk port: :) ratchet$ arp -a | grep net net02.2ndsiteinc.com (10.12.0.11) at 00:0C:29:1A:66:15 [ether] on eth0 net01.2ndsiteinc.com (10.12.0.10) at 00:11:43:D8:9F:94 [ether] on eth0 sw01#sh mac addr addr 00:0C:29:1A:66:15 Aging time is 300 sec Vlan Mac Address Port Type -------- --------------------- ---------- ---------- 12 00:0c:29:1a:66:15 gi11 dynamic sw01#sh mac addr addr 00:11:43:D8:9F:94 Aging time is 300 sec Vlan Mac Address Port Type -------- --------------------- ---------- ---------- 12 00:11:43:d8:9f:94 gi44 dynamic I also brought up an unused port on sw01 on vlan 12, but the unicast traffic was (as best as I could tell) not coming out that port. So it doesn't look like sw01 is pushing it out all its ports, just the right ports and also gi1! I've verified that sw01 is not filling up its address-table: sw01#sh mac addr count This may take some time. Capacity : 8192 Free : 7983 Used : 208 The full configs for both core01 and sw01 are available: core01, sw01. Finally, versions: sw01#sh ver SW version 1.1.2.0 ( date 12-Nov-2011 time 23:34:26 ) Boot version 1.0.0.4 ( date 08-Apr-2010 time 16:37:57 ) HW version V01 core01#sh ver SW version 1.1.2.0 ( date 12-Nov-2011 time 23:34:26 ) Boot version 1.1.0.6 ( date 11-May-2011 time 18:31:00 ) HW version V01 So my understanding is this: sw01 should take unicast traffic for net01 and send it only out net02's port, and vice versa; none of it should go out sw01's uplink. But core01, receiving traffic on gi1 for a host it knows is on gi1, is right in sending it out all of its ports. (That is: sw01 is misbehaving, but core01 is doing what it should given the circumstances.) My question is: Why is sw01 sending that unicast traffic out its uplink, gi1? (And pre-emptively: yes, I know SG300s leave much to be desired, and yes, we should have spanning-tree enabled, but that's where I'm at right now.)

  • How do I configure OpenVPN for accessing the internet with one NIC?

    - by Lekensteyn
    I've been trying to get OpenVPN to work for three days. After reading many questions, the HOWTO, the FAQ and even parts of a guide to Linux networking, I cannot get my an Internet connection to the Internet. I'm trying to set up a OpenVPN server on a VPS, which will be used for: secure access to the Internet bypassing port restrictions (directadmin/2222 for example) an IPv6 connection (my client does only have IPv4 connectivity, while the VPS has both IPv4 and native IPv6 connectivity) (if possible) I can connect to my server and access the machine (HTTP), but Internet connectivity fails completely. I'm using ping 8.8.8.8 for testing whether my connection works or not. Using tcpdump and iptables -t nat -A POSTROUTING -j LOG, I can confirm that the packets reach my server. If I ping to 8.8.8.8 on the VPS, I get an echo-reply from 8.8.8.8 as expected. When pinging from the client, I do not get an echo-reply. The VPS has only one NIC: etho. It runs on Xen. Summary: I want to have a secure connection between my laptop and the Internet using OpenVPN. If that works, I want to have IPv6 connectivity as well. Network setup and software: Home laptop (eth0: 192.168.2.10) (tap0: 10.8.0.2) | | (running Kubuntu 10.10; OpenVPN 2.1.0-3ubuntu1) | wifi | router/gateway (gateway 192.168.2.1) | INTERNET | VPS (eth0:1.2.3.4) (gateway, tap0: 10.8.0.1) (running Debian 6; OpenVPN 2.1.3-2) wifi and my home router should not cause problems since all traffic goes encrypted over UDP port 1194. I've turned IP forwarding on: # echo 1 > /proc/sys/net/ipv4/ip_forward iptables has been configured to allow forwarding traffic as well: iptables -F FORWARD iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -s 10.8.0.0/24 -j ACCEPT iptables -A FORWARD -j DROP I've tried each of these rules separately without luck (flushing the chains before executing): iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j SNAT --to 1.2.3.4 iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE route -n before (server): 1.2.3.4 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 1.2.3.4 0.0.0.0 UG 0 0 0 eth0 route -n after (server): 1.2.3.4 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.8.0.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0 0.0.0.0 1.2.3.4 0.0.0.0 UG 0 0 0 eth0 route -n before (client): 192.168.2.0 0.0.0.0 255.255.255.0 U 2 0 0 wlan0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 wlan0 route -n after (client): 1.2.3.4 192.168.2.1 255.255.255.255 UGH 0 0 0 wlan0 10.8.0.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0 192.168.2.0 0.0.0.0 255.255.255.0 U 2 0 0 wlan0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0 0.0.0.0 10.8.0.1 128.0.0.0 UG 0 0 0 tap0 128.0.0.0 10.8.0.1 128.0.0.0 UG 0 0 0 tap0 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 wlan0 SERVER config proto udp dev tap ca ca.crt cert server.crt key server.key dh dh1024.pem server 10.8.0.0 255.255.255.0 push "redirect-gateway def1" ifconfig-pool-persist ipp.txt keepalive 10 120 tls-auth ta.key 0 comp-lzo user nobody group nobody persist-key persist-tun log-append openvpn-log verb 3 mute 10 CLIENT config dev tap proto udp remote 1.2.3.4 1194 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key ns-cert-type server tls-auth ta.key 1 comp-lzo verb 3 mute 20 traceroute 8.8.8.8 works as expected (similar output without OpenVPN activated): 1 10.8.0.1 (10.8.0.1) 24.276 ms 26.891 ms 29.454 ms 2 gw03.sbp.directvps.nl (178.21.112.1) 31.161 ms 31.890 ms 34.458 ms 3 ge0-v0652.cr0.nik-ams.nl.as8312.net (195.210.57.105) 35.353 ms 36.874 ms 38.403 ms 4 ge0-v3900.cr0.nik-ams.nl.as8312.net (195.210.57.53) 41.311 ms 41.561 ms 43.006 ms 5 * * * 6 209.85.248.88 (209.85.248.88) 147.061 ms 36.931 ms 28.063 ms 7 216.239.49.36 (216.239.49.36) 31.109 ms 33.292 ms 216.239.49.28 (216.239.49.28) 64.723 ms 8 209.85.255.130 (209.85.255.130) 49.350 ms 209.85.255.126 (209.85.255.126) 49.619 ms 209.85.255.122 (209.85.255.122) 52.416 ms 9 google-public-dns-a.google.com (8.8.8.8) 41.266 ms 44.054 ms 44.730 ms If you have any suggestions, please comment or answer.

  • Integers not properly returned from a property list (plist) array in Objective-C

    - by Gaurav
    In summary, I am having a problem where I read what I expect to be an NSNumber from an NSArray contained in a property list and instead of getting a number such as '1', I get what looks to be a memory address (i.e. '61879840'). The numbers are clearly correct in the property list. Below is my process for creating the property list and reading it back. Creating the property list I have created a simple Objective-C property list with arrays of integers within one root array: <array> <array> <integer>1</integer> <integer>2</integer> </array> <array> <integer>1</integer> <integer>2</integer> <integer>5</integer> </array> ... more arrays with integers ... </array> The arrays are NSArray objects and the integers are NSNumber objects. The property list has been created and serialized using the following code: // factorArray is an NSArray that contains NSArrays of NSNumbers as described above // serialize and compress factorArray as a property list, Factors-bin.plist NSString *error; NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString *plistPath = [rootPath stringByAppendingPathComponent:@"Factors-bin.plist"]; NSData *plistData = [NSPropertyListSerialization dataFromPropertyList:factorArray format:NSPropertyListBinaryFormat_v1_0 errorDescription:&error]; Inspecting the created plist, all values and types are correct. Reading the property list The property list is read in as Data and then converted to an NSArray: NSString *path = [[NSBundle mainBundle] pathForResource:@"Factors" ofType:@"plist"]; NSData *plistData = [[NSData alloc] initWithContentsOfFile:path]; NSPropertyListFormat format; NSString *error = nil; NSArray *factorData = (NSArray *)[NSPropertyListSerialization propertyListFromData:plistData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error]; Cycling through factorData to see what it contains is where I see the erroneous integers: for (int i = 0; i < 10; i++) { NSArray *factorList = (NSArray *)[factorData objectAtIndex:i]; NSLog(@"Factors of %d\n", i + 1); for (int j = 0; j < [factorList count]; j++) { NSLog(@" %d\n", (NSNumber *)[factorList objectAtIndex:j]); } } I see all the correct number of values, but the values themselves are incorrect, i.e.: Factors of 3 61879840 (should be 1) 61961200 (should be 3) Factors of 4 61879840 (should be 1) 61943472 (should be 2) 61943632 (should be 4) Factors of 5 61879840 (should be 1) 61943616 (should be 5)

  • How can I read the verbose output from a Cmdlet in C# using Exchange Powershell

    - by mrkeith
    Environment: Exchange 2007 sp3 (2003 sp2 mixed mode) Visual Studio 2008, .Net 3.5 Hello, I'm working with an Exchange powershell move-mailbox cmdlet and have noted when I do so from the Exchange Management shell (using the Verbose switch) there is a ton of real-time information provided. To provide a little context, I'm attempting to create a UI application that moves mailboxes similarly to the Exchange Management Console but desire to support an input file and specific server/database destinations for each entry (and threading). Here's roughly what I have at present but I'm not sure if there is an event I need to register for or what... And to be clear, I desire to get this information in real-time so I may update my UI to reflect what's occurring in the move sequence for the appropriate user (pretty much like the native functionality offered in the Management Console). And in case you are wondering, the reason why I'm not content with the Management Console functionality is, I have an algorithm which I'm using to balance users depending on storage limit, Blackberry use, journaling, exception mailbox size etc which demands user be mapped to specific locations... and I do not desire to create many/several move groups for each common destination or to hunt for lists of users individually through the management console UI. I can not seem to find any good documentation or examples of how to tie into reading the verbose messages that are provided within the console using C# (I see value in being able to read this kind of information in many different scenarios). I've explored the Invoke and InvokeAsync methods and the StateChanged & DataReady events but none of these seem to provide the information (verbose comments) that I'm after. Any direction or examples that can be provided will be very appreciated! A code sample which is little more than how I would ordinarily call any other powershell command follows: // config to use ExMgmt shell, create runspace and open it RunspaceConfiguration rsConfig = RunspaceConfiguration.Create(); PSSnapInException snapInException = null; PSSnapInInfo info = rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out snapInException); if (snapInException != null) throw snapInException; Runspace runspace = RunspaceFactory.CreateRunspace(rsConfig); try { runspace.Open(); // create a pipeline and feed script text Pipeline pipeline = runspace.CreatePipeline(); string targetDatabase = @"myServer\myStorageGroup\myDB"; string mbxOwner = "[email protected]"; Command myMoveMailbox = new Command("Move-Mailbox", false, false); myMoveMailbox.Parameters.Add("Identity", mbxOwner); myMoveMailbox.Parameters.Add("TargetDatabase", targetDatabase); myMoveMailbox.Parameters.Add("Verbose"); myMoveMailbox.Parameters.Add("ValidateOnly"); myMoveMailbox.Parameters.Add("Confirm", false); pipeline.Commands.Add(myMoveMailbox); System.Collections.ObjectModel.Collection output = null; // these next few lines that are commented out are where I've tried // registering for events and calling asynchronously but this doesn't // seem to get me anywhere closer // //pipeline.StateChanged += new EventHandler(pipeline_StateChanged); //pipeline.Output.DataReady += new EventHandler(Output_DataReady); //pipeline.InvokeAsync(); //pipeline.Input.Close(); //return; tried these variations that are commented out but none seem to be useful output = pipeline.Invoke(); // Check for errors in the pipeline and throw an exception if necessary if (pipeline.Error != null && pipeline.Error.Count 0) { StringBuilder pipelineError = new StringBuilder(); pipelineError.AppendFormat("Error calling Test() Cmdlet. "); foreach (object item in pipeline.Error.ReadToEnd()) pipelineError.AppendFormat("{0}\n", item.ToString()); throw new Exception(pipelineError.ToString()); } foreach (PSObject psObject in output) { // blah, blah, blah // this is normally where I would read details about a particular PS command // but really pertains to a command once it finishes and has nothing to do with // the verbose messages that I'm after... since this part of the methods pertains // to the after-effects of a command having run, I'm suspecting I need to look to // the asynch invoke method but am not certain or knowing how. } } finally { runspace.Close(); } Thanks!

  • How can I pass latitude and longitude values from UIViewController to MKMapView?

    - by jerincbus
    I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.mapAddress = self.address; mapController.mapTitle = self.Title; mapController.mapLat = self.lat; mapController.mapLng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; //mapController = nil; } And on my MapViewController.h file I have: #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import "DetailViewController.h" #import "CourseAnnotation.h" @class CourseAnnotation; @interface MapViewController : UIViewController <MKMapViewDelegate> { IBOutlet MKMapView *mapView; NSString *mapAddress; NSString *mapTitle; NSNumber *mapLat; NSNumber *mapLng; } @property (nonatomic, retain) IBOutlet MKMapView *mapView; @property (nonatomic, retain) NSString *mapAddress; @property (nonatomic, retain) NSString *mapTitle; @property (nonatomic, retain) NSNumber *mapLat; @property (nonatomic, retain) NSNumber *mapLng; @end And on the pertinent parts of the MapViewController.m file I have: @synthesize mapView, mapAddress, mapTitle, mapLat, mapLng; - (void)viewDidLoad { [super viewDidLoad]; [mapView setMapType:MKMapTypeStandard]; [mapView setZoomEnabled:YES]; [mapView setScrollEnabled:YES]; MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center.latitude = mapLat; //40.105085; region.center.longitude = mapLng; //-83.005237; region.span.longitudeDelta = 0.01f; region.span.latitudeDelta = 0.01f; [mapView setRegion:region animated:YES]; [mapView setDelegate:self]; CourseAnnotation *ann = [[CourseAnnotation alloc] init]; ann.title = mapTitle; ann.subtitle = mapAddress; ann.coordinate = region.center; [mapView addAnnotation:ann]; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

  • java.sql.SQLException: Parameter number X is not an OUT parameter

    - by Frederik
    Hi guys, I'm struggling with getting the result OUT variable from a MySQL stored procedure. I get the following error: java.sql.SQLException: Parameter number 3 is not an OUT parameter The stored procedure looks like this: CREATE DEFINER=`cv_admin`@`localhost` PROCEDURE `CheckGameEligibility`( IN gID INT(10), IN uID INT(10), OUT result TINYINT(1) ) BEGIN # Do lots of stuff, then eventually: SET result = 1; END My java function takes an array of strings* and creates the CallableStatement object dynamically: public static int callAndReturnResult( String sql , String[] values ) { int out = 0 ; try { // construct the SQL. Creates: CheckGameEligibility(?, ?, ?) sql += "(" ; for( int i = 0 ; i < values.length ; i++ ) { sql += "?, " ; } sql += "?)" ; System.out.println( "callAndReturnResult("+sql+"): constructed SQL: " + sql ); // Then the statement CallableStatement cstmt = DB.prepareCall( sql ); for( int i = 0 ; i < values.length ; i++ ) { System.out.println( " " + (i+1) + ": " + values[ i ] ) ; cstmt.setString(i+1, values[ i ] ); } System.out.println( " " + (values.length+1) + ": ?

Anyway, here's the output it generates: callAndReturnResult(CheckGameEligibility(?, ?, ?)): constructed SQL: CheckGameEligibility(?, ?, ?) 1: 57 2: 29 3: ?

  • OSX 10.6 Cisco IPSEC strange behavior

    I'm trying to connect to Cisco IPSEC VPN of my company over DSL Internet. I managed to successfully connect using Cisco VPN Client, now I'm trying to switch to OSX 10.6 native client, because of licensing issues.

  • error working with wsdl files in visual studio 2008

    - by deostroll
    Hi. I got a wsdl file in email. At first I didn't know how to use it. I've simply saved the file to my disk. Opened visual studio...added a service reference...provided path to file, and service was discovered. I opened the object browser to see the types and methods that got imported. I figure anything that ends with the name 'Client' is a good place to start using the web service. I've tried using a simple method to get data but it has run into and expception. Need help in resolving it. System.InvalidOperationException was unhandled Message="The XML element 'ListsRequest' from namespace 'http://www.asd.org/MGMMIRAGE.MDM.WS/Customer' references a method and a type.

  • Trouble cross-referencing two XML child nodes in AS3

    - by Dwayne
    I am building a mini language translator out of XML nodes and Actionscript 3. I have my XML ready. It contains a series of nodes with two children in them. Here is a sample: <translations> <entry> <english>man</english> <cockney>geeza</cockney> </entry> <entry> <english>woman</english> <cockney>lily</cockney> </entry> </translations> The AS3 part consist of one input box named "textfield_txt" where the English word will be typed in. An output text field for the translation called "cockney_txt". Finally, one button to execute the translation called "generate_mc". The idea is to have actionscript look through the XML for key English words after the user types it in the "textfield", cross-freferences the children then returns the Cockney translation as a value. The trouble is, when I test it I get no response or error messages- it's completely silent. I'm not sure what I'm doing wrong. At present, I have setup a conditional statement to tell me whether the function works or not. The result is, no it's not! Here's the code below. I hope someone can help. Cheers! generate_mc.buttonMode=true; var English:String; var myXML:XML; var myLoader:URLLoader = new URLLoader(); myLoader.load(new URLRequest("Language.xml")); myLoader.addEventListener(Event.COMPLETE, processXML); function processXML(e:Event):void { myXML = new XML(e.target.data); } generate_mc.addEventListener(MouseEvent.CLICK, onClick); function onClick(event:MouseEvent) { English = textfield.text; cockney_txt.text = myXML.translations.entry.cockney; if(textfield.text.toLowerCase() == myXML.translations.entry.english.toLowerCase){ //return myXML.translations.entry.cockney; trace("success"); }else{ trace("try again!"); // ***I get this as a result } }

  • A format for storing personal contacts in a database

    - by Gart
    I'm thinking of the best way to store personal contacts in a database for a business application. The traditional and straightforward approach would be to create a table with columns for each element, i.e. Name, Telephone Number, Job title, Address, etc... However, there are known industry standards for this kind of data, like for example vCard, or hCard, or vCard-RDF/XML or even Windows Contacts XML Schema. Utilizing an standard format would offer some benefits, like inter-operablilty with other systems. But how can I decide which method to use? The requirements are mainly to store the data. Search and ordering queries are highly unlikely but possible. The volume of the data is 100,000 records at maximum. My database engine supports native XML columns. I have been thinking to use some XML-based format to store the personal contacts. Then it will be possible to utilize XML indexes on this data, if searching and ordering is needed. Is this a good approach? Which contacts format and schema would you recommend for this? Edited after first answers Here is why I think the straightforward approach is bad. This is due to the nature of this kind of data - it is not that simple. The personal contacts it is not well-structured data, it may be called semi-structured. Each contact may have different data fields, maybe even such fields which I cannot anticipate. In my opinion, each piece of this data should be treated as important information, i.e. no piece of data could be discarded just because there was no relevant column in the database. If we took it further, assuming that no data may be lost, then we could create a big text column named Comment or Description or Other and put there everything which cannot be fitted well into table columns. But then again - the data would lose structure - this might be bad. If we wanted structured data then - according to the database design principles - the data should be decomposed into entities, and relations should be established between the entities. But this adds complexity - there are just too many entities, and lots of design desicions should be made, like "How do we store Address? Personal Name? Phone number? How do we encode home phone numbers and mobile phone numbers? How about other contact info?.." The relations between entities are complex and multiple, and each relation is a table in the database. Each relation needs to be documented in the design papers. That is a lot of work to do. But it is possible to avoid the complexity entirely - just document that the data is stored according to such and such standard schema, period. Then anybody who would be reading that document should easily understand what it was all about. Finally, this is all about using an industry standard. The standard is, hopefully, designed by some clever people who anticipated and described the structure of personal contacts information much better than I ever could. Why should we all reinvent the wheel?? It's much easier to use a standard schema. The problem is, there are just too many standards - it's not easy to decide which one to use!

  • Java Hardware Acceleration

    - by Freezerburn
    I have been spending some time looking into the hardware acceleration features of Java, and I am still a bit confused as none of the sites that I found online directly and clearly answered some of the questions I have. So here are the questions I have for hardware acceleration in Java: 1) In Eclipse version 3.6.0, with the most recent Java update for Mac OS X (1.6u10 I think), is hardware acceleration enabled by default? I read somewhere that someCanvas.getGraphicsConfiguration().getBufferCapabilities().isPageFlipping() is supposed to give an indication of whether or not hardware acceleration is enabled, and my program reports back true when that is run on my main Canvas instance for drawing to. If my hardware acceleration is not enabled now, or by default, what would I have to do to enable it? 2) I have seen a couple articles here and there about the difference between a BufferedImage and VolatileImage, mainly saying that VolatileImage is the hardware accelerated image and is stored in VRAM for fast copy-from operations. However, I have also found some instances where BufferedImage is said to be hardware accelerated as well. Is BufferedImage hardware accelerated as well in my environment? What would be the advantage of using a VolatileImage if both types are hardware accelerated? My main assumption for the advantage of having a VolatileImage in the case of both having acceleration is that VolatileImage is able to detect when its VRAM has been dumped. But if BufferedImage also support acceleration now, would it not have the same kind of detection built into it as well, just hidden from the user, in case that the memory is dumped? 3) Is there any advantage to using someGraphicsConfiguration.getCompatibleImage/getCompatibleVolatileImage() as opposed to ImageIO.read() In a tutorial I have been reading for some general concepts about setting up the rendering window properly (tutorial) it uses the getCompatibleImage method, which I believe returns a BufferedImage, to get their "hardware accelerated" images for fast drawing, which ties into question 2 about if it is hardware accelerated. 4) This is less hardware acceleration, but it is something I have been curious about: do I need to order which graphics get drawn? I know that when using OpenGL via C/C++ it is best to make sure that the same graphic is drawn in all the locations it needs to be drawn at once to reduce the number of times the current texture needs to be switch. From what I have read, it seems as if Java will take care of this for me and make sure things are drawn in the most optimal fashion, but again, nothing has ever said anything like this clearly. 5) What AWT/Swing classes support hardware acceleration, and which ones should be used? I am currently using a class that extends JFrame to create a window, and adding a Canvas to it from which I create a BufferStrategy. Is this good practice, or is there some other type of way I should be implementing this? Thank you very much for your time, and I hope I provided clear questions and enough information for you to answer my several questions.

  • How to do validation on both client and server side for a service which is a store procedure(return a complex type)

    - by Tai
    Hi I am doing Silverlight 4 In my database, I have a store procedure(having two parameters) which returns rows (with extra fields). So i have to make a complex type for those rows on my Models. And Making a service to call that function import store procedure. The RIA will automatically create a matching Entity(to the complex type) and an operation for me. However, I don't know how to validation the parameters of the operation on both client and server side. For example, the parameter must be an integer only (and greater than 10) or datetime only. below is my xaml code. I am using DomainDataSource control and don't know how to validate the two field parameter.It has two TextBox to let the user types in the value of parameters.

  • Adding UL to jQuery UI Tabs

  • Linux Device Driver: Symbol "memcpy" not found

    - by Hinton
    Hello, I'm trying to write a Linux device driver. I've got it to work really well, until I tried to use "memcpy". I don't even get a compiler error, when I "make" it just warns me: WARNING: "memcpy" [/root/homedir/sv/main.ko] undefined! OK and when I try to load via insmod, I get on the console: insmod: error inserting './main.ko': -1 Unknown symbol in module and on dmesg: main: Unknown symbol memcpy (err 0) I include the following: #include <linux/module.h> #include <linux/moduleparam.h> #include <linux/init.h> #include <linux/kernel.h> /* printk() */ #include <linux/slab.h> /* kmalloc() */ #include <linux/fs.h> /* everything... */ #include <linux/errno.h> /* error codes */ #include <linux/types.h> /* size_t */ #include <linux/fcntl.h> /* O_ACCMODE */ #include <linux/cdev.h> #include <asm/system.h> /* cli(), *_flags */ #include <asm/uaccess.h> /* copy_*_user */ The function using memcpy: static int dc_copy_to_user(char __user *buf, size_t count, loff_t *f_pos, struct sv_data_dev *dev) { char data[MAX_KEYLEN]; size_t i = 0; /* Copy the bulk as long as there are 10 more bytes to copy */ while (i < (count + MAX_KEYLEN)) { memcpy(data, &dev->data[*f_pos + i], MAX_KEYLEN); ec_block(dev->key, data, MAX_KEYLEN); if (copy_to_user(&buf[i], data, MAX_KEYLEN)) { return -EFAULT; } i += MAX_KEYLEN; } return 0; } Could someone help me? I thought the thing was in linux/string.h, but I get the error just the same. I'm using kernel 2.6.37-rc1 (I'm doing in in user-mode-linux, which works only since 2.6.37-rc1). Any help is greatly appreciated. # Context dependent makefile that can be called directly and will invoke itself # through the kernel module building system.

  • Oracle sample data problems

    - by Jay
    So, I have this java based data trasformation / masking tool, which I wanted to test out on Oracle 10g. The good part with Oracle 10g is that you get a load of sample schemas with half a million records in some. The schemas are : SH, OE, HR, IX and etc. So, I installed 10g, found out that the installation scripts are under ORACLE_HOME/demo/scripts. I customized these scripts a bit to run in batch mode. That solves one half of my requirement - to create source data for my testing my data transformation software. The second half of the requirement is that I create the same schemas under different names (TR_HR, TR_OE and so on...) without any data. These schemas would represent my target schemas. So, in short, my software would pick up data from a table in a schema and load it up in to the same table in a different schema. Now, I have two issues in creating my target schema and emptying it. I would like this in a batch job. But the oracle scripts you get, the sample schema names are not configurable. So, I tried creating a script, replacing OE with TR_OE, HR with TR_HR and so on. However, this approach is kind of irritating coz the sample schemas are kind of complicated in the way they are created; Oracle creates synonyms, views, materialized views, data types and lot of weird stuff. I would like the target schemas (TR_HR, TR_OE,...) to be empty. But some of the schemas have circular references, which would not allow me to delete data. The only work around seems to be removing certain foreign keys, deleting data and then adding the constraints back. Is there any easy way to all this, without all this fuss? I would need a complicated data set for my testing (complicated as in tables with triggers, multiple hierarchies.. for instance.. a child table that has children up to 5 levels, a parent table that refers to an IOT table and an IOT table that refers to a non-IOT table etc..). The sample schemas are just about perfect from a data set perspective. The only challenge I see is in automating this whole process of loading up the source schemas, and then creating the target schemas and emptying them. Appreciate your help and suggestions.
