  • What do these .NET auto-generated table adapter commands do? e.g. UPDATE/INSERT followed by a SELECT

    - by RickL
    I'm working with a legacy application which I'm trying to change so that it can work with SQL CE, whilst it was originally written against SQL Server. The problem I am getting now is that when I try to do dataAdapter.Update, SQL CE complains that it is not expecting the SELECT keyword in the command text. I believe this is because SQL CE does not support batch SELECT statements. The auto-generated table adapter command looks like this... this._adapter.InsertCommand.CommandText = @"INSERT INTO [Table] ([Field1], [Field2]) VALUES (@Value1, @Value2); SELECT Field1, Field2 FROM Table WHERE (Field1 = @Value1)"; What is it doing? It looks like it is inserting new records from the datatable into the database, and then reading that record back from the database into the datatable? What's the point of that? Can I just go through the code and remove all these SELECT statements? Or is there an easier way to solve my problem of wanting to use these data adapters with SQL CE? I cannot regenerate these table adapters, as the people who knew how to have long since left.

  • Need to call original function from detoured function

    - by peachykeen
    I'm using Detours to hook into an executable's message function, but I need to run my own code and then call the original code. From what I've seen in the Detours docs, it definitely sounds like that should happen automatically. The original function prints a message to the screen, but as soon as I attach a detour it starts running my code and stops printing. The original function code is roughly: void CGuiObject::AppendMsgToBuffer(classA, unsigned long, unsigned long, int, classB); My function is: void CGuiObject_AppendMsgToBuffer( [same params, with names] ); I know the memory position the original function resides in, so using: DWORD OrigPos = 0x0040592C; DetourAttach( (void*)OrigPos, CGuiObject_AppendMsgToBuffer); gets me into the function. This code works almost perfectly: my function is called with the proper parameters. However, execution leaves my function and the original code is not called. I've tried jmping back in, but that crashes the program (I'm assuming the code Detours moved to fit the hook is responsible for the crash). Edit: I've managed to fix the first issue, with no returning to program execution. By calling the OrigPos value as a function, I'm able to go to the "trampoline" function and from there on to the original code. However, somewhere along the lines the registers are changing and that is causing the program to crash with a segfault as soon as I get back into the original code.

    - by Daryl Gill
    I'm Programming on a Windows Server 2008 and I wish to have a WebUI to interact with the domains active directory. One of my main problems is this that i'm using dsadd from a HTML form but this is no succeeding. I know my command is correct, I have tested it out on the Servers Command line My Code is As Below: if (isset($_POST['Submit'])) { $DesiredUsername = $_POST['DesiredUsername']; $DesiredPassword = $_POST['DesiredPassword']; $DU = "{$DesiredUsername}"; // Desired Username $OU = "PHPCreatedUsers"; // Domain OU $DC1 = "slayerserv"; // Domain Part one $DC2 = "local"; // Domain Part Two $PWD = "{$DesiredPassword}"; // Password $ExecScript = 'dsadd user cn=$DesiredUsername,cn=PHPCreatedUsers,dc=slayerserv,dc=local -disabled no -pwd $DesiredPassword -mustchpwd yes'; exec($ExecScript, $output); mysql_query("INSERT INTO addedusers (`ID`, `DU`, `OU`, `DC1`, `DC2, `PWD`) VALUES ('', '$DU', '$OU', '$DC1', '$DC2', '$PWD')"); echo "<br><br>"; print_r($output); # echo "User: $DesiredUsername Has been Created"; } When I print_r($output); it Returns a blank array: Array ( ) Could anyone provide me with a solution or point me in the right direction? ++++ Below is a working example of my usage of exec $Script = 'ping 127.0.0.1 -n 1'; exec($Script, $Output); print_r($Output); print_r($Output); Gives: Array ( [0] = [1] = Pinging 127.0.0.1 with 32 bytes of data: [2] = Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 [3] = [4] = Ping statistics for 127.0.0.1: [5] = Packets: Sent = 1, Received = 1, Lost = 0 (0% loss), [6] = Approximate round trip times in milli-seconds: [7] = Minimum = 0ms, Maximum = 0ms, Average = 0ms )

  • how to push a string address to stack with assembly, machine code

    - by Yigit
    Hi all, I am changing minesweeper.exe in order to have an understanding of how code injection works. Simply, I want the minesweeper to show a message box before starting. So, I find a "cave" in the executable and then define the string to show in messagebox and call the messagebox. Additionally of course, I have to change the value at module entry point of the executable and first direct it to my additional code, then continue its own code. So at the cave what I do; "hello starbuck",0 push 0 //arg4 of MessageBoxW function push the address of my string //arg3, must be title push the address of my string //arg2, must be the message push 0 //arg1 call MessageBoxW ... Now since the memory addresses of codes in the executable change everytime it is loaded in the memory, for calling the MessageBoxW function, I give the offset of the address where MessageBoxW is defined in Import Address Table. For instance, if MessageBoxW is defined at address1 in the IAT and the instruction just after call MessageBoxW is at address2 instead of writing call MessageBoxW, I write call address2 - address1. So my question is, how do I do it for pushing the string's address to the stack? For example, if I do these changes via ollydbg, I give the immediate address of "hello starbuck" for pushing and it works. But after reloading the executable or starting it outside of ollydbg, it naturally fails, since the immediate addresses change. Thanks in advance, Yigit.

  • Playing wave file ends immediatly (C++, Windows)

    - by TyBoer
    I've got a following situation. On a machine there is a Fritz ISDN card. There is a process that is responsible for playing a certain wave file on this device's wave out (ISDN connection is made at startup and made persistent). The scenario is easy, whenever needed the process calls waveOutWrite() on the previously opened wave device (everything initialized without any problems of course) and a callback function waits for MMWOMDONE msg to know that the playback has been finished. Since a few days however (nothing changed neither in the process nor the machine) the MMWOMDONE message comes immediately after calling waveOutWrite() even though the wave lasts a couple of seconds. Again no error is reported, it looks like the file was played but had zero length (which is not the case). I am also sure that waveOutReset() was not called by my process (it would also trigger sending the mentioned message). I already used to have some strange problems in the past that where solved simply by reinstalling TAPI drivers. This time for some reason it is problematic form me to perform that once again and am trying more analytical approach :). Any suggestions what might cause such a behavior? Maybe sth on the other end of the ISDN line?

  • Can I programmatically add a linkbutton to gridview?

    - by pschorf
    I've been looking through some similar questions without any luck. What I'd like to do is have a gridview which for certain items shows a linkbutton and for other items shows a hyperlink. This is the code I currently have: public void gv_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { var data = (FileDirectoryInfo)e.Row.DataItem; var img = new System.Web.UI.HtmlControls.HtmlImage(); if (data.Length == null) { img.Src = "/images/folder.jpg"; var lnk = new LinkButton(); lnk.ID = "lnkFolder"; lnk.Text = data.Name; lnk.Command += new CommandEventHandler(changeFolder_OnCommand); lnk.CommandArgument = data.Name; e.Row.Cells[0].Controls.Add(lnk); } else { var lnk = new HyperLink(); lnk.Text = data.Name; lnk.Target = "_blank"; lnk.NavigateUrl = getLink(data.Name); e.Row.Cells[0].Controls.Add(lnk); img.Src = "/images/file.jpg"; } e.Row.Cells[0].Controls.AddAt(0, img); } } where the first cell is a TemplateField. Currently, everything displays correctly, but the linkbuttons don't raise the Command event handler, and all of the controls disappear on postback. Any ideas?

  • Can't return a List from a Compiled Query.

    - by Andrew
    I was speeding up my app by using compiled queries for queries which were getting hit over and over. I tried to implement it like this: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id) End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, List(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ (From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u).ToList()) This did not work and I got this error message: Type : System.ArgumentNullException, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : Value cannot be null. Parameter name: value However, when I changed my compiled query to return IQueryable instead of List like so: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id).ToList() End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, IQueryable(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u) It worked fine. Can anyone shed any light as to why this is? BTW, compiled queries rock! They sped up my app by a factor of 2.

  • Sensible unit test possible?

    - by nkr1pt
    Could a sensible unit test be written for this code which extracts a rar archive by delegating it to a capable tool on the host system if one exists? I can write a test case based on the fact that my machine runs linux and the unrar tool is installed, but if another developer who runs windows would check out the code the test would fail, although there would be nothing wrong with the extractor code. I need to find a way to write a meaningful test which is not binded to the system and unrar tool installed. How would you tackle this? public class Extractor { private EventBus eventBus; private ExtractCommand[] linuxExtractCommands = new ExtractCommand[]{new LinuxUnrarCommand()}; private ExtractCommand[] windowsExtractCommands = new ExtractCommand[]{}; private ExtractCommand[] macExtractCommands = new ExtractCommand[]{}; @Inject public Extractor(EventBus eventBus) { this.eventBus = eventBus; } public boolean extract(DownloadCandidate downloadCandidate) { for (ExtractCommand command : getSystemSpecificExtractCommands()) { if (command.extract(downloadCandidate)) { eventBus.fireEvent(this, new ExtractCompletedEvent()); return true; } } eventBus.fireEvent(this, new ExtractFailedEvent()); return false; } private ExtractCommand[] getSystemSpecificExtractCommands() { String os = System.getProperty("os.name"); if (Pattern.compile("linux", Pattern.CASE_INSENSITIVE).matcher(os).find()) { return linuxExtractCommands; } else if (Pattern.compile("windows", Pattern.CASE_INSENSITIVE).matcher(os).find()) { return windowsExtractCommands; } else if (Pattern.compile("mac os x", Pattern.CASE_INSENSITIVE).matcher(os).find()) { return macExtractCommands; } return null; } }

  • How to run crontab-e?

    - by user1723760
    I am currently reading this documentation here where I want to use CRON. Now it says in the first section that I need to enter in a command: crontab -e. Do I only need to enter this in a simple text editor file and just upload the file into the server? I am using helios.hud.ac.uk so would this be the correct command: * * 25 10 * helios.hud.ac.uk/u00000000/Mobile/inactivatesession.php This will execute this php script below (inactivatesession.php): <?php include('connect.php'); $createDate = mktime(0,0,0,10,25,date("Y")); $selectedDate = date('d-m-Y', ($createDate)); $sql = "UPDATE Session SET Active = ? WHERE DATE_FORMAT(SessionDate,'%Y-%m-%d' ) <= ?"; $update = $mysqli->prepare($sql); $update->bind_param("is", 0, $selectedDate); $update->execute(); ?> The url for this php script is: helios.hud.ac.uk/u00000000/Mobile/inactivatesession.php I havn't used CRON before so just need little help on it.

  • C++ boost.asio server and client connection undersanding

    i started learning boost.asio and i have some problems with undersanding tcp connections.

  • Execute less compiler anywhere on the computer

    - by Xenioz
    I'm having a little problem with executing *.cmd files so I can execute them anywhere on the computer with cmd. What I exactly want is to execute the less.cmd file, which support optional arguments and uses lessc.wsf (Less.js compiler for Windows Script Host) for converting less css to pure css. The less.cmd contains: ::For convenience @cscript //nologo "%~dp0lessc.wsf" %* What I've done so far: added absolute path to lessc.cmd to the PATH system variable and moved .cmd in the PATHTEXT system variable to the beginning. Also did this: From a command prompt; assoc .bat should return with ..bat=batfile If not assoc .bat=batfile to restore the default file type association. ftype batfile should return with batfile="%1" %* If not ftype batfile="%1" %* to restore the default "Open" action for the file type. This still doesn't work unless I approach the cmd file with a absolute path in cmd, if I enter lessc anywhere else then I get C:\Intel Intel is not recognized as an internal or external command, operable program or batch file. , I've restarted my computer more than once to be sure changes will take effect. I hope somebody has the answer.

  • How to compile ocaml to native code

    - by Indra Ginanjar
    i'm really interested learning ocaml, it fast (they said it could be compiled to native code) and it's functional. So i tried to code something easy like enabling mysql event scheduler. #load "unix.cma";; #directory "+mysql";; #load "mysql.cma";; let db = Mysql.quick_connect ~user:"username" ~password:"userpassword" ~database:"databasename"();; let sql = Printf.sprintf "SET GLOBAL EVENT_SCHEDULER=1;" in (Mysql.exec db sql);; It work fine on ocaml interpreter, but when i was trying to compile it to native (i'm using ubuntu karmic), neither of these command worked ocamlopt -o mysqleventon mysqleventon.ml unix.cmxa mysql.cmxa ocamlopt -o mysqleventon mysqleventon.ml unix.cma mysql.cma i also tried ocamlc -c mysqleventon.ml unix.cma mysql.cma all of them resulting same message File "mysqleventon.ml", line 1, characters 0-1: Error: Syntax error Then i tried to remove the "# load", so the code goes like this let db = Mysql.quick_connect ~user:"username" ~password:"userpassword" ~database:"databasename"();; let sql = Printf.sprintf "SET GLOBAL EVENT_SCHEDULER=1;" in (Mysql.exec db sql);; The ocamlopt resulting message File "mysqleventon.ml", line 1, characters 9-28: Error: Unbound value Mysql.quick_connect I hope someone could tell me, where did i'm doing wrong.

  • Pass Variable to Java Method from an Ant Target

    - by user200317
    At the moment I have a .properties file to store settings related to the framework. Example: default.auth.url=http://someserver-at008:8080/ default.screenshots=false default.dumpHTML=false And I have written a class to extract those values and here is the method of that class. public static String getResourceAsStream(String defaultProp) { String defaultPropValue = null; //String keys = null; try { InputStream inputStream = SeleniumDefaultProperties.class.getClassLoader().getResourceAsStream(PROP_FILE); Properties properties = new Properties(); //load the input stream using properties. properties.load(inputStream); defaultPropValue = properties.getProperty(defaultProp); }catch (IOException e) { log.error("Something wrong with .properties file, check the location.", e); } return defaultPropValue; } Throughout the application I use method like follows to just exact property needed, public String getBrowserDefaultCommand() { String bcmd = SeleniumDefaultProperties.getResourceAsStream("default.browser.command"); if(bcmd.equals("")) handleMissingConfigProperties(SeleniumDefaultProperties.getResourceAsStream("default.browser.command")); return bcmd; } But I have not decided do a change to this and use ant and pass a parameter instead of using it from .properties file. I was wondering how could I pass a value to a Java Method using ANT. Non of these classes have Main methods and will not have any main. Due to this I was unable to use it as a java system properties. Thanks in advance.

  • Is this OleDbDataAdapter bug

    - by ????
    It doesn't look to me OleDbDataAdapter should throw an exception on trying to fill DataSet for a db table column of type decimal(28,3). The message is "The numerical value is too large to fit into a 96 bit decimal". Could you just check this, I have no significant experience with ADO.NET and OLE DB components? The VB.NET code we have in the application is this: Dim dbDataSet As New DataSet Dim dbDataAdapter As OleDbDataAdapter Dim dbCommand As OleDbCommand Dim conn As OleDbConnection Dim connectionString As String 'parts where connectionString is set conn = New OleDbConnection(connectionString) 'part where sqlQuery is set but it ends up being "SELECT Price As 'Price' From PricebookView" - Price is of type decimal(28,3) dbCommand = New OleDbCommand(sqlQuery, conn) dbCommand.CommandTimeout = cmdTimeout dbDataAdapter = New OleDbDataAdapter(dbCommand) dbDataAdapter.Fill(dbDataSet) The last line is where the exception is thrown and the top of the stack trace is: at System.Data.ProviderBase.DbBuffer.ReadNumeric(Int32 offset) at System.Data.OleDb.ColumnBinding.Value_NUMERIC() at System.Data.OleDb.ColumnBinding.Value() at System.Data.OleDb.OleDbDataReader.GetValues(Object[] values) at System.Data.ProviderBase.DataReaderContainer.CommonLanguageSubsetDataReader.GetValues(Object[] values) at System.Data.ProviderBase.SchemaMapping.LoadDataRow() at System.Data.Common.DataAdapter.FillLoadDataRow(SchemaMapping mapping) at System.Data.Common.DataAdapter.FillFromReader(DataSet dataset, DataTable datatable, String srcTable, DataReaderContainer dataReader, Int32 startRecord, Int32 maxRecords, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DataAdapter.Fill(DataSet dataSet, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords) at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet) ...

  • How do you configure an SDL Tridion CME extension for a subset of views?

    - by Chris Summers
    I have created a new editor for SDL Tridion which adds some new functionality to the ribbon bar. This is enabled by adding the following snippet to the editor.config <!-- ItemCommenting PowerTool --> <ext:extension assignid="ItemCommenting" name="Save and&lt;br/&gt;Comment" pageid="HomePage" groupid="ManageGroup" insertbefore="SaveCloseBtn"> <ext:command>PT_ItemCommenting</ext:command> <ext:title>Save and Comment</ext:title> <ext:issmallbutton>false</ext:issmallbutton> <ext:dependencies> <cfg:dependency>PowerTools.Commands</cfg:dependency> </ext:dependencies> <ext:apply> <ext:view name="*" /> </ext:apply> </ext:extension> This is applied to all views by using a wildcard value in the node. This has results in my new button being added to the ribbon of every view, including the main dashboard. Is there a way to add this to all views except for the dashboard? Or do I have to create something like this? <ext:apply> <ext:view name="PageView" /> <ext:view name="ComponentView" /> <ext:view name="SchemaView" /> </ext:apply> If this is the only way to achieve the result I need, is there a list of all the view names somewhere?

  • PHPUnit reporting "Aborted" no matter what tests are run

    - by GrumpyCanuck
    Having a weird problem with PHPUnit. We're using PHPUnit as part of a continuous integration environment, that contains one app written using Zend Framework and one app written using CodeIgniter. Unit tests run just fine under Zend Framework, but whenever I run the tests for CodeIgniter using fooStack's CIUnit bridge, I always get the same problem at the end: PHPUnit 3.4.14 by Sebastian Bergmann. ............... . Time: 1 second, Memory: 7.00Mb OK (16 tests, 14 assertions) Aborted First off, I do not know what those empty spaces between the . means. Secondly, no matter what test I run (all of them or each one separately) I get the same Aborted message at the very end. The tests themselves do not contain any exit or die statements. When I run the same version of PHPUnit on my laptop (running OS-X Snow Leopard and same version of Zend Server Community Edition) I do not get that aborted message. Running PHP 5.3.2 on Ubuntu installed using Zend Server Community Edition. Any help with this would be greatly appreciated.

The data are sent by another device with the following frame format: |start | Command | Data | CRC | End | |0x02 | 0x41 | (0-127 octets) | | 0x03| ---------------------------------------------------- The Data field contains 127 octets as shown and octet 1,2 contains one type of data; octet 3,4 contains another data. I need to get these data I know how to write and read data to and from a serial port in Linux, but it is just to write and read a simple string (like "ABD") My issue is that I do not know how to parse the data frame formatted as above so that I can: get the data in octet 1,2 in the Data field get the data in octet 3,4 in the Data field get the value in CRC field to check the consistency of the data Here the sample snip code that read and write a simple string from and to a serial port in Linux: int writeport(int fd, char *chars) { int len = strlen(chars); chars[len] = 0x0d; // stick a <CR> after the command chars[len+1] = 0x00; // terminate the string properly int n = write(fd, chars, strlen(chars)); if (n < 0) { fputs("write failed!\n", stderr); return 0; } return 1; } int readport(int fd, char *result) { int iIn = read(fd, result, 254); result[iIn-1] = 0x00; if (iIn < 0) { if (errno == EAGAIN) { printf("SERIAL EAGAIN ERROR\n"); return 0; } else { printf("SERIAL read error %d %s\n", errno, strerror(errno)); return 0; } } return 1; } Does anyone please have some ideas? Thanks all.

  • Where should you put 3rd party .NET dlls when using git submodules to avoid duplication

    - by Tim Abell
    I have two .NET library projects in Visual Studio 2008 that both make use of the MySql Connector for .NET (MySql.Data.dll). These libraries are then in turn both used by a .NET command line application which also uses the Connector. The library projects are pulled in to the application's solution as git submodules and referenced by project in Visual Studio. I'm looking for the most effective strategy for storing and referencing the MySql Connector library. I have tried having the MySql.Data.dll checked in to all three projects (in their root folder), this was problematic when one project changed to a newer version of the connector dll. Although each project had its own version of the dll, only one was packaged into the resultant application leading to an API mismatch which was hard to pin down. This has put me off this approach. I have tried having the command line application reference the connector dll that is held in a submodule, however this only removes the possibility of version mismatches when there is only one submodule rather than two as in this case. I am contemplating putting the dll in the global assembly cache (GAC) of all machines that need to build or use the application, but I'm wary of not having all dependencies for an application available in source control.

  • Turbogears 2.0 with Python 2.6

    - by AKSK
    I've tried to install TurboGears 2.0 with Python 2.6 on both Windows 7 and Windows XP, but both give the same error: File "D:\PythonProjects\tg2env\Scripts\paster-script.py", line 8, in <module> load_entry_point('pastescript==1.7.3', 'console_scripts', 'paster')() File "D:\PythonProjects\tg2env\lib\site-packages\pastescript-1.7.3-py2.6.egg\paste\script\command.py", line 73, in run commands = get_commands() File "D:\PythonProjects\tg2env\lib\site-packages\pastescript-1.7.3-py2.6.egg\paste\script\command.py", line 115, in get_ plugins = pluginlib.resolve_plugins(plugins) File "D:\PythonProjects\tg2env\lib\site-packages\pastescript-1.7.3-py2.6.egg\paste\script\pluginlib.py", line 81, in res pkg_resources.require(plugin) File "D:\PythonProjects\tg2env\lib\site-packages\setuptools-0.6c9-py2.6.egg\pkg_resources.py", line 626, in require File "D:\PythonProjects\tg2env\lib\site-packages\setuptools-0.6c9-py2.6.egg\pkg_resources.py", line 524, in resolve pkg_resources.DistributionNotFound: zope.sqlalchemy>=0.4: Not Found for: City_Guide (did you run python setup.py develop?) Now, according to the documentation on the main site, TurboGears 2.0 supports Python 2.6 in this page: TurboGears works with any version of python between 2.4 and 2.6. The most widely deployed version of python at the moment of this writing is version 2.5. Both python 2.4 and python 2.6 require additional steps which will be covered in the appropriate sections. But they never mention those steps in the documentation.

  • Generating MySQL UPDATE statements containing BLOB image data

    - by Bob
    I'm trying to write an SQL statement that will generate an SQL script that will update a BLOB field with an IMAGE being selected from the database. This is what I have: select concat( 'UPDATE `IMAGE` SET THUMBNAIL = ', QUOTE( THUMBNAIL ), ' WHERE ID = ', ID, ';' ) as UPDATE_STATEMENT from IMAGE; In the above, THUMBNAIL is a BLOB field containing raw image data. When I run the resulting script I get the following error: ERROR at line 2: Unknown command '\\'. I first tried this without the QUOTE() function, like so: select concat( 'UPDATE `IMAGE` SET THUMBNAIL = \'', THUMBNAIL, '\' WHERE ID = ', ID, ';' ) as UPDATE_STATEMENT from IMAGE; Running the resulting script produces this error: ERROR at line 2: Unknown command '\0'. What is the proper function to apply to this BLOB field in the select, so the UPDATE statements will work? If context is required, I'm looking to migrate thumbnails generated on one server to another server for certain image IDs only. I would use mysqldump, but I don't want to clobber the entire table. Any help is greatly appreciated!

  • Java SSH2 libraries in depth: Trilead/Ganymed/Orion [/other?]

    - by Bernd Haug
    I have been searching for a pure Java SSH library to use for a project. The single most important needed feature is that it has to be able to work with command-line git, but remote-controlling command-line tools is also important. A pretty common choice, e.g. used in the IntelliJ IDEA git integration (which works very well), seems to be Trilead SSH2. Looking at their website, it's not being maintained any more. Trilead seems to have been a fork of Ganymed SSH2, which was a ETH Zurich project that didn't see releases for a while, but had a recent release by its new owner, Christian Plattner. There is another actively maintained fork from that code base, Orion SSH, that saw an even more recent release, but which seems to get mentioned online much less than the other 2 forks. Has anybody here worked with any of (or, if possible, both) of Ganymed and Orion and could kindly describe the development experience with either/both? Accuracy of documentation [existence of documentation?], stability, buggyness... - all of these would be highly interesting to me. Performance is not so important for my current project. If there is another pure-Java SSH implementation that should be used instead, please feel free to mention it, but please don't just mention a name...describe your judgment from actual experience. Sorry if this question may seem a bit "do my homework"-y, but I've really searched for reviews. Everything out there seems to be either a listing of implementations or short "use this! it's great!" snippets.

  • Is there a way to make changes to toggles in my .emacs file apply without re-starting Emacs?

    - by Vivi
    I want to be able to make the changes to my .emacs file without having to reload Emacs. I found three questions which sort of answer what I am asking (you can find them here, here and here), but the problem is that the change I have just made is to a toggle, and as the comments to two of the answers (a1, a2) to those questions explain, the solutions given there (such as M-x reload-file or M-x eval-buffer) don't apply to toggles. I imagine there is a way of toggling the variable again with a command, but if there is a way to reload the whole .emacs and have the all the toggles re-evaluated without having to specify them, I would prefer. In any case, I would also appreciate if someone told me how to toggle the value of a variable so that if I just changed one toggle I can do it with a command rather than re-start Emacs just for that (I am new to Emacs). I don't know how useful this information is, but the change I applied was the following (which I got from this answer to another question): (setq skeleton-pair t) (setq skeleton-pair-on-word t) (global-set-key (kbd "[") 'skeleton-pair-insert-maybe) (global-set-key (kbd "(") 'skeleton-pair-insert-maybe) (global-set-key (kbd "{") 'skeleton-pair-insert-maybe) (global-set-key (kbd "<") 'skeleton-pair-insert-maybe) Edit: I included the above in .emacs and reloaded Emacs, so that the changes took effect. Then I commented all of it out and tried M-x load-file. This doesn't work. The suggestion below (C-x C-e by PP works if I am using it to evaluate the toggle first time, but not when I want to undo it). I would like something that would evaluate the commenting out, if such thing exists... Thanks :)
