  • is it possible to do partial postback on web?

    - by carter-boater
    Hi all, I read some paragraphs in a book saying that it is not possible to do a partial postback for web, even AJAX is employed. Ajax will postback everything and update only ajaxfied controls. However, on pages I made using ajax, I used Fiddler to monitor the transportation. I found when the page initial load, it loaded everything include pictures .... However, when I click a button and do a ajax postback. I can only see the some data were loaded.... Looks like it doesn't need to reload the whole page again. I don't know if what I see is correct? Or the book I read is correct? Thank you guys.

  • INSERT INTO temporary table from sp_executsql

    - by gotqn
    Generally, I am bulding dynamic SQL statement that is executing using sp_executsql like this: EXEC sp_executesql @TempSQLStatement I need to insert the return result row set in something (table variable or temporary table), but I am getting the following error: Msg 208, Level 16, State 0, Line 1746 Invalid object name '#TempTable'. after executing this: INSERT INTO #TempTable EXEC sp_executesql @TempSQLStatement From what I have read, I believe the issue is caused because I am not specifying the columns of the temporary table, but I am not able to do this because the return columns count varies. I have read that I can use global temporary tables, but I have done this before and wonder is there an other way to do that.

  • Saving Blob data from SQLite database to a file

    - by Felipe
    Hello, I'm trying to save blob data from a SQLite database (Safari cache: Cache.db) to a file, but for some reason sqlite won't read the whole blob. I eventually would like to do this in ruby, but for now something that works directly in sqlite command prompt is fine. Also, I've read all of the entries that talk about this here on stackoverflow, but most of them only discuss the performance of saving images in blobs and the one entry that does show to save blobs to file is in C# which does not help me. Here is what I've tried: sqlite select * from cfurl_cache_response limit 1; 3501|0|945281827|0|http://www.gospelz.com/components/com_jomcomment/smilies/guest.gif|2010-02-24 16:20:07 sqlite select receiver_data from cfurl_cache_blob_data where entry_ID = 3501; GIF89a( A hexdump of the original (guest.gif) file shows that sqlite stops reading the blob after the first null value: $ hexdump -C guest.gif 00000000 47 49 46 38 39 61 28 00 28 00 f7 00 00 f1 f5 fd |GIF89a(.(.......| sqlite .output test.gif sqlite select receiver_data from cfurl_cache_blob_data where entry_ID = 3501; $ hexdump -C test.gif 00000000 47 49 46 38 39 61 28 0a |GIF89a(.|

  • How can I parse a C header file with Perl?

    - by Alphaneo
    Hi, I have a header file in which there is a large struct. I need to read this structure using some program and make some operations on each member of the structure and write them back. For example I have some structure like const BYTE Some_Idx[] = { 4,7,10,15,17,19,24,29, 31,32,35,45,49,51,52,54, 55,58,60,64,65,66,67,69, 70,72,76,77,81,82,83,85, 88,93,94,95,97,99,102,103, 105,106,113,115,122,124,125,126, 129,131,137,139,140,149,151,152, 153,155,158,159,160,163,165,169, 174,175,181,182,183,189,190,193, 197,201,204,206,208,210,211,212, 213,214,215,217,218,219,220,223, 225,228,230,234,236,237,240,241, 242,247,249}; Now, I need to read this and apply some operation on each of the member variable and create a new structure with different order, something like: const BYTE Some_Idx_Mod_mul_2[] = { 8,14,20, ... ... 484,494,498}; Is there any Perl library already available for this? If not Perl, something else like Python is also OK. Can somebody please help!!!

  • A Question About Embedding HTML In PHP

    - by Brian
    Hello all Some time ago I read a posting on a board where the person was talking poorly about people that have HTML embedded/within their PHP. I do quite a bit of PHP development but I still interleave HTML and PHP in the same document. Is there a better way to do this, am I doing it wrong? I know that in JSP/JSF they use an XML document with namespaces to insert their HTML code so I was wondering if there was a similar function that PHP uses that I should be taking advantage of. Thanks for taking the time to read. :-)

  • Check if table exists in c#

    - by apoorv020
    I want to read data from a table whose name is supplied by a user. So before actually starting to read data, I want to check if the database exists or not. I have seen several pieces of code on the NET which claim to do this. However, they all seem to be work only for SQL server, or for mysql, or some other implementation. Is there not a generic way to do this? (I am already seperately checking if I can connect to the supplied database, so I'm fairly certain that a connection can be opened to the database.)

  • setting up log4j for gmail, does not recognize System.setProperty("mail.smtps.port", "587")

    - by Alex Le
    Hi I am trying to setup a smtpappender for log4j using gmail as the smtp host. I have read that the port number needs to be 465 or 587 (depending on tls or ssl) and that log4j for some reason doesnt allow a different port to be set inside log4j.properties configuration file. I have read that the best way of doing this would be to use System.setProperty which would change the default javaxmail port to gmail. However when I try to set the System.property entries the the default port still remains as 25 System.setProperty("mail.smtp.starttls.enable", "true"); System.setProperty("mail.smtp.port", "587"); I was wondering if someone could help me out, I am open to suggestions, I just need to smtpAppender to work for gmail, dont really care how to get it to work. Thanks

  • Is it possible to "intercept" a 3rd party library's "WriteFile" operation

    - by stout
    This is likely a long shot, but I thought I'd ask anyway. I'm using a document management system's API. They provide a "WriteFile" method to save a given document to disk. However, the library does not have a way to simply read a document into memory. My only option, it seems, is to write to disk, then read it back in again. I'm wondering if there is a better way to work around this obvious limitation. Thanks in advance!

  • MS Sql Full-text search vs. LIKE expression

    - by Marks
    Hi. I'm currently looking for a way to search a big database (500MB - 10GB or more on 10 tables) with a lot of different fields(nvarchars and bigints). Many of the fields, that should be searched are not in the same table. An example: A search for '5124 Peter' should return all items, that ... have an ID with 5124 in it, have 'Peter' in the title or description have item type id with 5124 in it created by a user named 'peter' or a user whose id has 5124 in it created by a user with '5124' or 'peter' in his street address. How should i do the search? I read that the full-text search of MS-Sql is a lot more performant than a query with the LIKE keyword and i think the syntax is more clear, but i think it cant search on bigint(id) values and i read it has performance problems with indexing and therefore slows down inserts to the DB. In my project there will be more inserting than reading, so this could be a matter. Thanks in advance, Marks

  • How to change page author in wordpress?

    - by GaVrA
    Ofc i know how to do that, but the thing is that i am using "User Role Editor" and i have one user group that can read and edit published pages. Now, i will be adding all the pages on that site, and we will have several users that will need to have only one page they can edit, so i need for that page to change "Page author" to that user. In case you didnt know, when user have "Edit published pages" enabled they can edit only pages where they are listed as author. Problem is i can only do that by going in phpmyadmin and changing the page_author field to the id of that user because that user group, like i said, can only read and edit published pages. That is why i can not change page author from "Edit page" page to user from that user group. So my question is: does anyone know any solution to this problem which does not involve me going to phpmyadmin and changing the id for page_author there?

  • Invoke Haskell function with heterogeneous arguments?

    - by thurn
    I'm currently working on a Haskell project which automatically tests some functions based on an XML specification. The XML specification gives the arguments to each function and the expected result that the function will provide (the arguments are of many different types). I know how to extract the function arguments from the XML and parse them using the read function, but I haven't figured out how to invoke the function using the arguments I get out. What I basically want is to read and store the arguments in a heterogeneous list (my current thinking is to use a list of type Data.Dynamic) and then invoke the function, passing this heterogeneous list as its argument list. Is this possible? Modifying the functions under test is not an option.

  • Feeding PDF through IInternetSession to WebBrowser control - Error

    - by Codesleuth
    As related to my previous question, I have developed a temporary asynchronous pluggable protocol with the specific aim to be able to serve PDF documents directly to a WebBrowser control via a database. I need to do this because my limitations include not being able to access the disk other than IsolatedStorage; and a MemoryStream would be far better for serving up PDF documents that average around 31kb. Unfortunately the code doesn't work, and I'm getting an error from the WebBrowser control (i.e. IE): Unable to download . Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. The line in my code where this occurs is within the following: pOIProtSink.ReportData(BSCF.BSCF_LASTDATANOTIFICATION, (uint)_stream.Length, (uint)_stream.Length); However, if you download the project and run it, you will be able to see the stream is successfully read and passed to the browser, so it seems like there's a problem somewhere to do with the end of reading the data: public uint Read(IntPtr pv, uint cb, out uint pcbRead) { var bytesToRead = Math.Min(cb, _streamBuffer.Length); pcbRead = (uint)_stream.Read(_streamBuffer, 0, (int)bytesToRead); Marshal.Copy(_streamBuffer, 0, pv, (int)pcbRead); return (pcbRead == 0 || pcbRead < cb) ? HRESULT.S_FALSE : HRESULT.S_OK; } Here is the entire sample project: InternetSessionSample.zip (VS2010) I will leave this up for as long as I can to help other people in the future If anyone has any ideas why I might be getting this message and can shed some light on the problem, I would be grateful for the assistance. EDIT: A friend suggested inserting a line that calls the IInternetProtocolSink.ReportProgress with BINDSTATUS_CACHEFILENAMEAVAILABLE pointing at the original file. This prevents it from failing now and shows the PDF in the Adobe Reader control, but means it defeats the purpose of this by having Adobe Reader simply load from the cache file (which I can't provide). See below: pOIProtSink.ReportProgress(BINDSTATUS.BINDSTATUS_CACHEFILENAMEAVAILABLE, @"D:\Visual Studio Solutions\Projects\InternetSessionSample\bin\Debug\sample.pdf"); pOIProtSink.ReportData(BSCF.BSCF_LASTDATANOTIFICATION, (uint)_stream.Length, (uint)_stream.Length); This is progress though, I guess.

  • Unmanaged Code calling leads to heavy memory leak!!

    - by konnychen
    Maybe I need change the title as "Unmanaged Code calling leads to heavy memory leak!" The leak is around 30M/hour I think maybe I need complete my code here because the memory leak maybe not from a static string whereas my real code derive this string from external device (see new code attached). so I handle also unmanaged code. Could it be possible the leak comes from unmanaged code? But I freed the resouce by Marshal.FreeCoTaskMem(pos); oThread2 = new Thread(new ThreadStart(Cyclic_Call)); oThread2.Start(); delegate void SetText_lab_Statubar(string text); private void m_SetText_lab_Statubar(string text) { if (this.lab_Statubar.InvokeRequired) { SetText_lab_Statubar d = new SetText_lab_Statubar(m_SetText_lab_Statubar); this.Invoke(d, new object[] { text }); } else { this.lab_Statubar.Text = text; } } private void Cyclic_Call() { do { //... ...

  • data directory in automake

    - by Alex Farber
    I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only. How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.

  • sqlcipher command line not working

    - by Min Lin
    I have a encrypted sqlite db and its key. (Which is generated by an android program). However, when I open the db in command line I can not read the db. The command line tool is installed by: brew install sqlcipher I open the database by: sqlcipher EnDB.db >pragma key="6b74fcd"; >select * from bizinfo; It keeps telling me "Error: file is encrypted or is not a database" However, if I open the database file with gui app sqlite database browser (which is a windows program and I run it in wine). It pops up a window for me to enter the key, with 6b74fcd as the key it successfully read the database. As I want to automatically process the db in the future, I can not depend on the GUI. Do you know why the command line is not working?

  • PostgreSQL - best way to return an array of key-value pairs

    - by Matt W
    I'm trying to select a number of fields, one of which needs to be an array with each element of the array containing two values. Each array item needs to contain a name (character varying) and an ID (numeric). I know how to return an array of single values (using the ARRAY keyword) but I'm unsure of how to return an array of an object which in itself contains two values. The query is something like SELECT t.field1, t.field2, ARRAY(--with each element containing two values i.e. {'TheName', 1 }) FROM MyTable t I read that one way to do this is by selecting the values into a type and then creating an array of that type. Problem is, the rest of the function is already returning a type (which means I would then have nested types - is that OK? If so, how would you read this data back in application code - i.e. with a .Net data provider like NPGSQL?) Any help is much appreciated.

  • How to use Event notification in Solaris 10 when a directory change

    - by user357594
    I read the following page: Robert Benson's article on ECF developers.sun.com/solaris/articles/event_completion.html I also read the Solaris man pages but they are not very clear of how to use event notifications for directories. For example, If I add a new file into a directory, I would like to get some notification of that event. I found this link: blogs.sun.com/praks/entry/file_events_notification Which has what I need but it is for Solaris 11 ( which is not in the market yet). Based on the link below, I don't want to use poll because I want to get the performance advantage of events. blogs.sun.com/dap/entry/event_ports_and_performance Any suggestion is highly appreciated! -Armando.

  • help merging perl code routines together for file processing

    I need some perl help in putting these (2) processes/code to work together. I was able to get them working individually to test, but I need help bringing them together especially with using the loop constructs.

  • facebook with openid

    - by Stacey
    Referencing http://stackoverflow.com/questions/1827997/is-facebook-an-openid-provider here. This is kind of an additional question based on it. I have also read the article at : http://stackoverflow.com/questions/2264266/what-is-the-openid-url-of-facebook - but I am still pretty confused on the whole ordeal. The goal is for people who use facebook to easily login to our website, not to neccessarily integrate with facebook and add things to it (yet). I have read the documentation on facebook connect and am still having trouble grasping exactly what we need to do to accomplish this. I notice that it says that facebook accepts openid logins - so in theory someone with a facebook account could login to a site that took other openid logins, correct? Or do I have to code a separate 'facebookconnect' system just to accept logins from facebook accounts?

  • Error using CreateFileMapping - C

    - by Jamie Keeling
    Hello, I am using the tutorial on this MSDN link to implement a way of transferring data from one process to another. Although I was advised in an earlier question to use the Pipe methods, due to certain constraints I have no choice but to use the CreateFileMapping method. Now, i've succesfully managed to make two seperate window form projects within the same solution and by editing some properties both of the forms load at the same time. Furthermore I have managed to implement the code given in the MSDN sample into the first (Producer) and second (Consumer) program without any compilation errors. The problem I am having now is when I run the first program and try to create the handle to the mapped file, I am given an error saying it was unsuccesful and I do not understand why this is happening. I have added both the Producer and Consumer code files to demonstrate what I am trying to do. Producer: #include <windows.h> #include <stdio.h> #include <conio.h> //File header definitions #define IDM_FILE_ROLLDICE 1 #define IDM_FILE_QUIT 2 #define BUF_SIZE 256 TCHAR szName[]=TEXT("Global\\MyFileMappingObject"); TCHAR szMsg[]=TEXT("Message from first process!"); void AddMenus(HWND); LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM); ////Standard windows stuff - omitted to save space. ////////////////////// // WINDOWS FUNCTION // ////////////////////// LRESULT CALLBACK WindowFunc(HWND hMainWindow, UINT message, WPARAM wParam, LPARAM lParam) { WCHAR buffer[256]; LPCTSTR pBuf; struct DiceData storage; HANDLE hMapFile; switch(message) { case WM_CREATE: { // Create Menus AddMenus(hMainWindow); } break; case WM_COMMAND: // Intercept menu choices switch(LOWORD(wParam)) { case IDM_FILE_ROLLDICE: { //Roll dice and store results in variable //storage = RollDice(); ////Copy results to buffer //swprintf(buffer,255,L"Dice 1: %d, Dice 2: %d",storage.dice1,storage.dice2); ////Show via message box //MessageBox(hMainWindow,buffer,L"Dice Result",MB_OK); hMapFile = CreateFileMapping( (HANDLE)0xFFFFFFFF, // use paging file NULL, // default security PAGE_READWRITE, // read/write access 0, // maximum object size (high-order DWORD) BUF_SIZE, // maximum object size (low-order DWORD) szName); // name of mapping object if (hMapFile == NULL) { MessageBox(hMainWindow,L"Could not create file mapping object",L"Error",NULL); return 1; } pBuf = (LPTSTR) MapViewOfFile(hMapFile, // handle to map object FILE_MAP_ALL_ACCESS, // read/write permission 0, 0, BUF_SIZE); if (pBuf == NULL) { MessageBox(hMainWindow,L"Could not map view of file",L"Error",NULL); CloseHandle(hMapFile); return 1; } CopyMemory((PVOID)pBuf, szMsg, (_tcslen(szMsg) * sizeof(TCHAR))); _getch(); UnmapViewOfFile(pBuf); CloseHandle(hMapFile); } break; case IDM_FILE_QUIT: SendMessage(hMainWindow, WM_CLOSE, 0, 0); break; } break; case WM_DESTROY: PostQuitMessage(0); break; } return DefWindowProc(hMainWindow, message, wParam, lParam); } // //Setup menus // Consumer: #include <windows.h> #include <stdio.h> #include <conio.h> //File header definitions #define IDM_FILE_QUIT 1 #define IDM_FILE_POLL 2 #define BUF_SIZE 256 TCHAR szName[]=TEXT("Global\\MyFileMappingObject"); //Prototypes void AddMenus(HWND); LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM); //More standard windows creation, again omitted. ////////////////////// // WINDOWS FUNCTION // ////////////////////// LRESULT CALLBACK WindowFunc(HWND hMainWindow, UINT message, WPARAM wParam, LPARAM lParam) { HANDLE hMapFile; LPCTSTR pBuf; switch(message) { case WM_CREATE: { // Create Menus AddMenus(hMainWindow); break; } case WM_COMMAND: { // Intercept menu choices switch(LOWORD(wParam)) { case IDM_FILE_POLL: { hMapFile = OpenFileMapping( FILE_MAP_ALL_ACCESS, // read/write access FALSE, // do not inherit the name szName); // name of mapping object if (hMapFile == NULL) { MessageBox(hMainWindow,L"Could not open file mapping object",L"Error",NULL); return 1; } pBuf = (LPTSTR) MapViewOfFile(hMapFile, // handle to map object FILE_MAP_ALL_ACCESS, // read/write permission 0, 0, BUF_SIZE); if (pBuf == NULL) { MessageBox(hMainWindow,L"Could not map view of file",L"Error",NULL); CloseHandle(hMapFile); return 1; } MessageBox(NULL, pBuf, TEXT("Process2"), MB_OK); UnmapViewOfFile(pBuf); CloseHandle(hMapFile); break; } case IDM_FILE_QUIT: SendMessage(hMainWindow, WM_CLOSE, 0, 0); break; } break; } case WM_DESTROY: { PostQuitMessage(0); break; } } return DefWindowProc(hMainWindow, message, wParam, lParam); } // //Setup menus // It's by no means tidy and final but it's just a start, thanks for any help.
