• How to insert large files in mysql database using php? [closed]

  - by anjan

  Hi! I want to upload a large file of size 10M max to my mysql database. Using .htaccess i changed the PHP's own file upload limit to "10485760" = 10M, i am able to upload files upto 10M size without any problem. But i can not insert the file in database if it is more that 1M in size. i am using file_get_contents to read all file data and pass it to the insert query as a string to be inserted into a LONGBLOB field. But files with more than 1M size is not being added to database, though i can use print_r($_FILES) to examine that the file uploaded correctly. Any help will be appreciated and i will need it within next 6 hours. So, please help! best regards, Anjan * This is a duplicate of http://stackoverflow.com/questions/492549/how-can-i-insert-large-files-in-mysql-db-using-php *

• Best neural network for certain type of pattern analysis?

  - by fred basset

  Hi All, I'm working on a system that will send telemetry data on machine operation back to a central server for analysis. One of the machine parameters we're measuring is motor current drawn vs time. After an operation is finished we plan to send back an array of currents vs time to the server. A successful operation would have a pattern like a trapezoid, problematic operations would have a pattern completely different, more like a large spike in values. Can anyone recommend a type of neural network that would be good at classifying these 1D vectors of current values into a pass/fail type output? Thanks, Fred

• "Method name expected" error when trying add a handler method to a delegate - C#

  - by zakplayyy

  I keep getting the error "Method name expected" when trying add the a method to a delegate. I have a delegate which is invoked when ever my game ends. The function I'm trying to add to the delegate stops a countdown from flashing (the method is in a static class). I've searched about and I'm still unsure why its not working. Here is the line causing the error: LivesManager.gameEnded += new LivesManager.EndGame(CountdownManager.DisableFlashTimer(this)); The this passes the current form to the method so it can disable the timer flash on the form. I have added methods from static classes to the same delegate before and it works fine, the only difference is that I'm passing the form as a paramater and then it doesn't like it. Is there any way to pass the form to the method without the error? Thanks in advance :)

• Guice Problem with Tests

  Hey I wrote a LudoGame and now I like to test it with a little GuiceInjection^^ I have an Interface IDie for my die. Now for the game I only need an IDie instead of a realdie = in tests I simply give the LudoGame a MokeDie to set up the Numbers I like to roll. The IDie has only one method: roll() which returns a int.

• PHP - login to a remote server, trough my own server, with HTTPS, cookies and proxy, and downloading the html

  - by Yunga Mohani

  Hello, so what i am trying to do is this: login to the other server with a PHP on my own server (either with my username and pass/or with my cookies) then have access to the page i want to display/download i want to write a PHP script that is located on my own server, that automatically does a login to another server, that uses HTTPS and a web form for login. after the login i have access to that page that i am trying to download. i dont know if it would be possible to login and download the html only with the cookies that i have in my browser through a previous login, or if i need to do the login in my php script through some https login method. can i do any of this with curl or fsocksopen or what would be the best way to realize this? thanks in advance!

• Cannot convert []string to []interface {}

  - by karlrh

  I'm writing some code, and I need it to catch the arguments and pass them through fmt.Println (I want its default behaviour, to write arguments separated by spaces and followed by a newline). However it takes []interface {} but flag.Args() returns a []string. Here's the code example package main import ( "fmt" "flag" ) func main() { flag.Parse() fmt.Println(flag.Args()...) } This returns the following error: ./example.go:10: cannot use args (type []string) as type []interface {} in function argument Is this a bug? Shouldn't fmt.Println take any array? By the way, I've also tried to do this: var args = []interface{}(flag.Args()) but I get the following error: cannot convert flag.Args() (type []string) to type []interface {} Is there a "Go" way to workaround this?

• Multiply without multiplication, division and bitwise operators, and no loops. Recursion

  - by lxx22

  public class MultiplyViaRecursion{ public static void main(String[] args){ System.out.println("8 * 9 == " + multiply(8, 9)); System.out.println("6 * 0 == " + multiply(6, 0)); System.out.println("0 * 6 == " + multiply(0, 6)); System.out.println("7 * -6 == " + multiply(7, -6)); } public static int multiply(int x, int y){ int result = 0; if(y > 0) return result = (x + multiply(x, (y-1))); if(y == 0) return result; if(y < 0) return result = -multiply(x, -y); return result; } } My question is very simple and basic, why after each "if" the "return" still cannot pass the compilation, error shows missing return.

• ASP.NET 3.5: GetCallbackEventReference doesn't work synchronously

  - by deadbug

  I have an ASP.NET 3.5 WebForm that leverages the frameworks Page.ClientScript.GetCallbackEventReference() method and I'd like some of the calls to be synchronous. Now, the documentation says that the 5th parameter (see below) controls this. Specifically, when you pass 'false' it's supposed to be a non-asynchronous call. However, regardless if it's true or false, it still processes the call asynchronously. Page.ClientScript.GetCallbackEventReference(this, "arg", "ReceiveServerData", "context",false); Is there a work-around for this or perhaps I'm doing something wrong? Thanks in advance for the assistance!

• jquery ui - making dialogs more "dynamic" ?

  - by mike

  Hello, I have a page that uses multiple dialogs for different things. Some dialogs may have buttons that others do not while other may need to be a different height than another... All of them have a set of params that will not change. My question, can I have a default like: $('.someElement').dialog({ width: 999, show: 'slide', hide: 'slide', ETC: 'some other option' }); and use it for all of my dialogs, then pass buttons or height to it dynamically when I open a dialog? It just seems wrong to have something like the above for every dialog I need... Thanks!

• [C++] Passing around objects to network packet handlers ?

  - by xeross

  Hey, I've been writing a networking server for a while now in C++ and have come to the stage to start looking for a way to properly and easily handle all packets. I am so far that I can figure out what kind of packet it is, but now I need to figure out how to get the needed data to the handler functions. I had the following in mind: Have a map of function pointers with the opcode as key and the function pointer as value Have all these functions have 2 arguments, packet and ObjectAccessor ObjectAccessor class contains various functions to fetch various items such as users and alike Perhaps pass the user's guid too so we can fetch it from the objectaccessor I'd like to know the various implementations others have come up with, so please comment on this idea and reply with your own implementations. Thanks, Xeross

• php calling classes functions in separate pages

  - by sys_debug

  I've worked with J2EE recently and like the idea of struts.xml where I can handle the redirection to pages based on return string from action classes. In PHP, in my new under-development site, I am trying to follow the MVC standards without an MVC framework used from the internet. So I create the controllers, models and views (empty now). The only thing I am really stuck at is when I submit the form in view (insert_product.php) then I will need to create another php page to handle the post data and pass them to controllers. Anyway of avoiding creating those pages and maybe having something like struts.xml? Even if I can post data directly to controller class, that would be good. Thanks,

• Create Macro With Several Variables

  - by Daniel

  I have several worksheets with similar code, so I'd like to turn it into a macro. My only problem is that there are several variables. So at certain points the code looks like this: Dim Msg_1 As String Dim Msg_2 As String Public Sub ListBox1_LostFocus() ListBox1.Height = 15 With ListBox1 Msg1 = "'" For i = 0 To .ListCount - 1 If .Selected(i) Then Msg1 = Msg1 & .List(i) & "','" End If Next i End With Msg1 = Left(Msg1, Len(Msg1) - 2) Sheets("Sheet1").Range("R3", "R3") = Msg1 End Sub and so on. How can I pass in a new value for Msg1, Msg2, Msg3 for each worksheet?

• C++ - Implementing my own stream

  - by HardCoder1986

  Hello! My problem can be described the following way: I have some data which actually is an array and could be represented as char* data with some size I also have some legacy code (function) that takes some abstract std::istream object as a param and uses that stream to retrieve data to operate. So, my question is the following - what would be the easy way to map my data to some std::istream object so that I can pass it to my function? I thought about creating a std::stringstream object from my data, but that means copying and (as I assume) isn't the best solution. Any ideas how this could be done so that my std::istream operates on the data directly? Thank you.

• name of the class that contains the method code

  - by kdlp

  I'm trying to find the name of the class that contains method code. In the example underneath I use self.__class__.__name__, but of course this returns the name of the class of which self is an instance and not class that contains the test() method code. b.test() will print 'B' while I would like to get 'A'. I looked into the inspect module documentation but did not find anything directly useful. class A: def __init__(self): pass def test(self): print self.__class__.__name__ class B(A): def __init__(self): A.__init__(self) a = A() b = B() a.test() b.test()

• Vim: `cd` to path stored in variable

  - by tsyu80

  I'm pretty new to vim, and I'm having a hard time understanding some subtleties with vim scripting. Specifically, I'm having trouble working with commands that expect an unquoted-string (is there a name for this?). For example cd some/unquoted/string/path The problem is that I'd like to pass a variable, but calling let pathname = 'some/path' cd pathname will try to change the current directory to 'pathname' instead of 'some/path'. One way around this is to use let cmd = 'cd ' . pathname execute cmd but this seems a bit roundabout. This StackOverflow question actually uses cd with a variable, but it doesn't work on my system ("a:path" is treated as the path as described above). I'm using cd as a specific example, but this behavior isn't unique to cd; for example, the edit command also behaves this way. (Is there a name for this type of command?)

I'd like to pass tag data if possible to identify the button.

• Microsoft SQL Server xml data

  - by cf_PhillipSenn

  This site has a technique to pass xml data around in Microsoft SQL Server: DECLARE @productIds xml SET @productIds ='<Products><id>3</id><id>6</id><id>15</id></Products>' SELECT ParamValues.ID.value('.','VARCHAR(20)') FROM @productIds.nodes('/Products/id') as ParamValues(ID) But what is the syntax if I add another field? The following does NOT work: DECLARE @productIds xml SET @productIds ='<Products><id>3</id><descr>Three</descr><id>6</id><descr>six</descr><id>15</id><descr>Fifteen</descr></Products>' SELECT ParamValues.ID.value('.','VARCHAR(20)') ,ParamValues.descr.value('.','VARCHAR(20)') FROM @productIds.nodes('/Products/id') as ParamValues(ID) Note: Maybe I've constructed my xml wrong.

• mysqldb python escaping ? or %s?

  - by asldkncvas

  Dear Everyone, I am currently using mysqldb. What is the correct way to escape strings in mysqldb arguments? Note that E = lambda x: x.encode('utf-8') 1) so my connection is set with charset='utf8'. These are the errors I am getting for these arguments: w1, w2 = u'??', u'??' 1) self.cur.execute("SELECT dist FROM distance WHERE w1=? AND w2=?", (E(w1), E(w2))) ret = self.cur.execute("SELECT dist FROM distance WHERE w1=? AND w2=?", (E(w1), E(w2)) ) File "build/bdist.linux-i686/egg/MySQLdb/cursors.py", line 158, in execute TypeError: not all arguments converted during string formatting 2) self.cur.execute("SELECT dist FROM distance WHERE w1=%s AND w2=%s", (E(w1), E(w2))) This works fine, but when w1 or w2 has \ inside, then the escaping obviously failed. I personally know that %s is not a good method to pass in arguemnts due to injection attacks etc.

• mod_rewrite replace all instances of ampersand with %26 for later

  - by Supernovah

  Hey there! I want to simply not use ampersand in my URL so I can pass ampersands further down into my system when a file is requested. The problem is Apache deals with it differently. I don't know how I already rewrite the requested file to index.php?url=$1 so I can see what it was, but if it has an ampersand in there, it can't continue past it! how can I escape the ampersand or turn it into it's hex equal (%26)? <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [QSA,L] </IfModule>`
