  • Binding dropdown list in a gridview edit item template

    - by Renju
    i can bind the dropdownlist in the edit item template. The drop down list is having null values. protected void grdDevelopment_RowDataBound(object sender, GridViewRowEventArgs e) { DropDownList drpBuildServers = new DropDownList(); if (grdDevelopment.EditIndex == e.Row.RowIndex) { drpBuildServers = (DropDownList)e.Row.Cells[0].FindControl("ddlBuildServers"); } } also getting an error Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

  • How to find NSOutlineView row index when using NSTreeController

    - by velocityb0y
    I'm using an NSTreeController to manage nodes for an NSOutlineView. When the user adds a new item, I create a new object and insert it: EntityViewEntityNode *newNode = [EntityViewEntityNode nodeWithName:@"New entity" entity:newObject]; // Insert at end of group // NSIndexPath *insertAt = [pathOfGroupNode indexPathByAddingIndex:[selected.children count]]; [entityCollectionTreeController insertObject:newNode atArrangedObjectIndexPath:insertAt]; Now I'd like to open the table column for edit so the user can name the new item. This seems logical: NSInteger row = [entityCollectionOutlineView rowForItem:newNode]; [entityCollectionOutlineView editColumn:0 row:row withEvent:nil select:YES]; However, row is always -1 indicating the object isn't found. Poking around reveals that the tree controller is not actually putting my objects directly in the tree, but is wrapping them in a node object of its own. Anyone have insight into how I would go about getting a row index relative to the outline view, so I can do this (without, hopefully, enumerating everything in the outline view and figuring out the mapping back to my node?)

  • How to run unittest under pydev for Django?

    - by photon
    I configured properties for my django project under pydev. I can run the django app under pydev or under console window. I can also run unittest for app under console window. But I have problems to run unittest under pydev. I guess it's something related to run configurations of pydev, so I made several trials, but with no success. Once I got messages like this: ImportError: Could not import settings 'D:\django_projects\MyProject' (Is it on sys.path? Does it have syntax errors?): No module named D:\django_projects\MyProject ERROR: Module: MyUnittestFile could not be imported. Another time I got messages like this: ImportError: Could not import settings 'MyProject.settngs' (Is it on sys.path? Does it have syntax errors?): No module named settngs 'ERROR: Module: MyUnittestFile could not be imported. I use pydev 1.5.6 on eclipse and windows xp. Any ideas for this problem?

  • XML: When to use attributes instead of child nodes?

    - by Rosarch
    For tree leaves in XML, when is it better to use attributes, and when is it better to use descendant nodes? For example, in the following XML document: <?xml version="1.0" encoding="utf-8" ?> <savedGame> <links> <link rootTagName="zombies" packageName="zombie" /> <link rootTagName="ghosts" packageName="ghost" /> <link rootTagName="players" packageName="player" /> <link rootTagName="trees" packageName="tree" /> </links> <locations> <zombies> <zombie> <positionX>41</positionX> <positionY>100</positionY> </zombie> <zombie> <positionX>55</positionX> <positionY>56</positionY> </zombie> </zombies> <ghosts> <ghost> <positionX>11</positionX> <positionY>90</positionY> </ghost> </ghosts> </locations> </savedGame> The <link> tag has attributes, but it could also be written as: <link> <rootTagName>trees</rootTagName> <packageName>tree</packageName> </link> Similarly, the location tags could be written as: <zombie positionX="55" positionY="56" /> instead of: <zombie> <positionX>55</positionX> <positionY>56</positionY> </zombie> What reasons are there to prefer one over the other? Is it just a stylistic issue? Any performance considerations?

  • Node.js mongoose: how to use the .in and .sort methods of a query?

    - by Chris
    Hi there, I'm trying to wrap my head around mongoose, but I'm having a hard time finding any kind of documentation for some of the more advanced query options, specifically the .in and .sort methods. What's the syntax for sorting, for example, a Person by age? db.model("Person").find().sort(???).all(function(people) { }); Then, let's say I want to find a Movie based on a genre, where a Movie can have many genres (in this case, an array of strings). Presumably, I'd use the .in function to accomplish that, but I'm not sure what the syntax would be. Or perhaps I don't have to use the .in method at all...? Either way, I'm lost. db.model("Movie").find().in(???).all(function(movies) { }); Anyone have any ideas? Or even better, a link to some comprehensive documentation? Thanks! Chris

  • What's wrong with this SQL UPDATE query?

    - by Tommo
    I wouldn't ask if i wasn't sure that i have 100% no idea why this isn't working, so, in PHP i'm simply trying to update a value in the MySQL database: The field im updating - Name: read - Type: tinyint - Length: 1 Here is the PHP code: do_SQL("UPDATE messages SET read=1 WHERE id='".$id."'"); The do_SQL function is working for everything else, so it's something wrong with this statement. I have tried putting 1 in '1' and it still didn't work.m The error is: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'read=1 WHERE id='1'' at line 1 Thanks for reading!

  • In Coldfusion, how do I init a component that is located above the current path folder?

    - by Dan Sorensen
    If I have a folder structure that looks like this: / /bin/myComponent.cfc /reports/index.cfm How do I initiate myComponent.cfc from index.cfm? myService = createObject("component", "bin.myComponent"); Using the dot syntax, I know how to go to deeper folders, but how to do I go up a folder, and down into the other folder? Using slash syntax it would be something like this: ../bin/myComponent.cfc But createObject() doesn't work that way. I'd like to keep a relative path so that I can move this folder to another server without breaking the paths. Ideas? Thanks!

  • How to reference a sql server with a slash (\) in its name?

    - by Bill Paetzke
    Givens: One SQL Server is named: DevServerA Another is named: DevServerB\2K5 Problem: From DevServerA, how can I write a query that references DevServerB\2K5? I tried a sample, dummy query (running it from DevServerA): SELECT TOP 1 * FROM DevServerB\2K5.master.sys.tables And I get the error: Msg 102, Level 15, State 1, Line 2 Incorrect syntax near '\.'. However, I know my syntax is almost correct, since the other way around works (running this query from DevServerB\2K5): SELECT TOP 1 * FROM DevServerA.master.sys.tables Please help me figure out how to reference DevServerB\2K5 from DevServerA. Thanks.

  • Insert multiple values using INSERT INTO

    - by Ben McCormack
    In SQL Server 2005, I'm trying to figure out why I'm not able to insert multiple fields into a table. The following query, which inserts one record, works fine: INSERT INTO [MyDB].[dbo].[MyTable] ([FieldID] ,[Description]) VALUES (1000,N'test') However, the following query, which specifies more than one value, fails: INSERT INTO [MyDB].[dbo].[MyTable] ([FieldID] ,[Description]) VALUES (1000,N'test'),(1001,N'test2') I get this message: Msg 102, Level 15, State 1, Line 5 Incorrect syntax near ','. When I looked up the help for INSERT in SQL Sever Management Studio, one of their examples showed using the "Values" syntax that I used (with groups of values in parentheses and separated by commas). The help documentation I found in SQL Server Management Studio looks like it's for SQL Server 2008, so perhaps that's the reason that the insert doesn't work. Either way, I can't figure out why it won't work.

  • Best way to Fingerprint and Verify html structure.

    - by Lukas Šalkauskas
    Hello there, I just want to know what is your opinion about how to fingerprint/verify html/links structure. The problem I want to solve is: fingerprint for example 10 different sites, html pages. And after some time I want to have possibility to verify them, so is, if site has been changed, links changed, verification fails, othervise verification success. My base Idea is to analyze link structure by splitting it in some way, doing some kind of tree, and from that tree generate some kind of code. But I'm still in brainstorm stage, where I need to discuss this with someone, and know other ideas. So any ideas, algos, and suggestions would be usefull.

  • C++ Unlocking a std::mutex before calling std::unique_lock wait

    - by Sant Kadog
    I have a multithreaded application (using std::thread) with a manager (class Tree) that executes some piece of code on different subtrees (embedded struct SubTree) in parallel. The basic idea is that each instance of SubTree has a deque that store objects. If the deque is empty, the thread waits until a new element is inserted in the deque or the termination criteria is reached. One subtree can generate objects and push them in the deque of another subtree. For convenience, all my std::mutex, std::locks and std::variable_condition are stored in a struct called "locks". The class Tree creates some threads that run the following method (first attempt) : void Tree::launch(SubTree & st, Locks & locks ) { /* some code */ std::lock_guard<std::mutex> deque_lock(locks.deque_mutex_[st.id_]) ; // lock the access to the deque of subtree st if (st.deque_.empty()) // check that the deque is still empty { // some threads are still running, wait for them to terminate std::unique_lock<std::mutex> wait_lock(locks.restart_mutex_[st.id_]) ; locks.restart_condition_[st.id_].wait(wait_lock) ; } /* some code */ } The problem is that "deque_lock" is still locked while the thread is waiting. Hence no object can be added in the deque of the current thread by a concurrent one. So I turned the lock_guard into a unique_lock and managed the lock/unlock manually : void launch(SubTree & st, Locks & locks ) { /* some code */ std::unique_lock<std::mutex> deque_lock(locks.deque_mutex_[st.id_]) ; // lock the access to the deque of subtree st if (st.deque_.empty()) // check that the deque is still empty { deque_lock.unlock() ; // unlock the access to the deque to enable the other threads to add objects // DATA RACE : nothing must happen to the unprotected deque here !!!!!! // some threads are still running, wait for them to terminate std::unique_lock<std::mutex> wait_lock(locks.restart_mutex_[st.id_]) ; locks.restart_condition_[st.id_].wait(wait_lock) ; } /* some code */ } The problem now, is that there is a data race, and I would like to make sure that the "wait" instruction is performed directly after the "deque_lock.unlock()" one. Would anyone know a way to create such a critical instruction sequence with the standard library ? Thanks in advance.

  • Is there a way to make vim display "virtual characters" before/after regular patterns in the buffer?

    - by Laurence Gonsalves
    Vim has list and listchars options that make vim display "virtual characters" (by which I mean characters that aren't actually in the buffer) in certain situations. For example, you can make trailing spaces look like something else, or add a visible character to represent the newline character. I'd like to be able to enable the display of certain characters either before or after certain regular patterns ((perhaps syntax items). Sort of like syntax highlighting, but instead of just changing the color/styling of characters that are in the buffer, I'd like to display extra characters that aren't in the buffer. For example, I'd like to display a virtual : (colon) after all occurrences of the word "where" that appear at the end of a line. Is this possible, and if so, what is the necessary vimscript to do it?

  • How to structure class to support imported 3d model ?

    - by brainydexter
    Hello, I've written a C++ library that reads in this 3d model file (collada DAE). uptil now, I would output a list of triangles and handle each at rendering stage. But now, I need to attach some Bounding sphere information with the imported model. I need some advice on how should I organize this in code. Here are some specs of the 3D file format: - 3D model is represented as a Tree consisting of nodes - each node can contain other nodes, geometry information, transformation etc My requirements: - a bounding sphere associated with each node, thereby yielding a tree of bounding sphere hierarchy for the model itself. - actual vertex information What would be the recommended way to deal with this situation? Thanks

  • vim opens my folds on paste. how to prevent that ?

    - by Stefano Borini
    There's something weird going on in my fortran folding. This is the example file module foo contains subroutine hello() end subroutine hello subroutine hello() end subroutine subroutine hello() end subroutine end module foo subroutine hello() end subroutine subroutine hello() end subroutine subroutine hello() end subroutine and this is the vimrc syntax on au! BufRead,BufNewFile *.f90 setfiletype fortran set foldmethod=syntax let fortran_fold=1 The annoying thing is the following. If I cut (dd) and paste (P) a folded subroutine outside the module/end module block, the freshly pasted fold stay closed. If I paste it inside the module/end module block, the newly pasted folded region appears instead unfolded. Can you reproduce the issue (vim 7.2 here) and do you know any workaround/fix ?

  • Difference between halo and mx namespace

    - by Andree
    Hi there ! As far as I know, the support for library://ns.adobe.com/flex/halo namespace has been dropped, and now we have to use library://ns.adobe.com/flex/mx instead (reference). Can someone provide if there's any difference between the two namespaces? I am just starting to learn Flex and this change make me confused. For example, if I have an <mx:Tree> tag in my mxml document, the compiler complains that <mx:Tree> could not be resolved to a component implementation. But if I change my mx namespace to use the old one instead (halo), it successfully compiled without error. Thanks. Andree Updated: By the way, I use Flex SDK command line compiler in Windows. mxmlc --version Version 4.0.0 build 10485

  • SQL Injection on INSERT

    - by freddy
    Hi, I'm currently testing Vulnerabiltys to SQL Injections for my companys application as an it-trainee. So I found, that the application is indeed vulnerable to injections because I can alter some of the insert statements. So I altered the insert Statement to this: INSERT INTO tablename( column, column1, column2, column3, column4,column5, column6, column7, column8 ) VALUES ( 10965972, 185796154, 25, 23,2023, '', CURRENT_DATE, 'v0201100', 18); DELETE * FROM tablename;-- , 2023,'a', CURRENT_DATE, 'v0201100', 18 ) I thought this should be a correct statement, but the MySQL Server returned this Error: MySQL Error: 1064 (You have an error in your SQL syntax;[...] Would be nice if somebody could help and tell my why the syntax is wrong... Thanks for your help :-)

  • String of KML needs to be converted to java objects

    - by spartikus
    I have a string of kml coming in on a request object. I have used xjc to create the kml java objects. I am looking for an easy way to create the kml nested java objects from this string. I could parse the string and create each object in the tree by hand but wouldn't it be cool if there was a library or something that would create the java objects for me? Something like KmlType type = parseKML(mykmlStringFromTheRequest); Then type would be a Tree of kml objects. Thanks for the help all.

  • Using Delphi or FFMpeg to create a movie from image sequence

    - by Hein du Plessis
    Hi all My Delphi app has created a squence called frame_001.png to frame_100.png. I need that to be compiled into a movie clip. I think perhaps the easiest is to call ffmpeg from the command line, according to their documentation: For creating a video from many images: ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi The syntax foo-%03d.jpeg specifies to use a decimal number composed of three digits padded with zeroes to express the sequence number. It is the same syntax supported by the C printf function, but only formats accepting a normal integer are suitable. From: http://ffmpeg.org/ffmpeg-doc.html#SEC5 However my files are (lossless) png format, so I have to convert using imagemagick first. My command line is now: ffmpeg.exe -f image2 -i c:\temp\wentelreader\frame_%05d.jpg -r 12 foo.avi But then I get the error: [image2 @ 0x133a7d0]Could not find codec parameters (Video: mjpeg) c:\temp\wentelreader\Frame_C:\VID2EVA\Tools\Mencoder\wentel.bat5d.jpg: could not find codec parameters What am I doing wrong? Alternatively can this be done easily with Delphi?
