  • Sening a file from memory (rather than disk) over HTTP using libcurl

    - by cinek1lol
    Hi! I would like to send pictures via a program written in C + +. - OK WinExec("C:\\curl\\curl.exe -H Expect: -F \"fileupload=@C:\\curl\\ok.jpg\" -F \"xml=yes\" -# \"http://www.imageshack.us/index.php\" -o data.txt -A \"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1\" -e \"http://www.imageshack.us\"", NULL); It works, but I would like to send the pictures from pre-loaded carrier to a variable char (you know what I mean? First off, I load the pictures into a variable and then send the variable), cause now I have to specify the path of the picture on a disk. I wanted to write this program in c++ by using the curl library, not through exe. extension. I have also found such a program (which has been modified by me a bit) #include <stdio.h> #include <string.h> #include <iostream> #include <curl/curl.h> #include <curl/types.h> #include <curl/easy.h> int main(int argc, char *argv[]) { CURL *curl; CURLcode res; struct curl_httppost *formpost=NULL; struct curl_httppost *lastptr=NULL; struct curl_slist *headerlist=NULL; static const char buf[] = "Expect:"; curl_global_init(CURL_GLOBAL_ALL); /* Fill in the file upload field */ curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "send", CURLFORM_FILE, "nowy.jpg", CURLFORM_END); curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "nowy.jpg", CURLFORM_COPYCONTENTS, "nowy.jpg", CURLFORM_END); curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "submit", CURLFORM_COPYCONTENTS, "send", CURLFORM_END); curl = curl_easy_init(); headerlist = curl_slist_append(headerlist, buf); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "http://www.imageshack.us/index.php"); if ( (argc == 2) && (!strcmp(argv[1], "xml=yes")) ) curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist); curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost); res = curl_easy_perform(curl); curl_easy_cleanup(curl); curl_formfree(formpost); curl_slist_free_all (headerlist); } system("pause"); return 0; }

  • How do I get real integer overflows in MATLAB/Octave?

    - by marvin2k
    I'm working on a verification-tool for some VHDL-Code in MATLAB/Octave. Therefore I need data types which generate "real" overflows: intmax('int32') + 1 ans = -2147483648 Later on, it would be helpful if I can define the bit width of a variable, but that is not so important right now. When I build a C-like example, where a variable gets increased until it's smaller than zero, it spins forever and ever: test = int32(2^30); while (test > 0) test = test + int32(1); end Another approach I tried was a custom "overflow"-routine which was called every time after a number is changed. This approach was painfully slow, not practicable and not working in all cases at all. Any suggestions?

  • RCP applicatoon activities

    - by Peter
    I have a problem with my RCP application. First, I defined an activity in my plugin.xml: <extension point="org.eclipse.ui.activities"> <activity id="myproject.view.input.activity" name="myproject.view.input.activity"> <enabledWhen> <with variable="myproject.view.input.active"> <equals value="ENABLED"> </equals> </with> </enabledWhen> </activity> <activityPatternBinding activityId="myproject.view.input.activity" pattern="myproject.gui/myproject.view.input"> </activityPatternBinding> Then i defined my SourceProvider: <extension point="org.eclipse.ui.services"> <sourceProvider provider="myproject.util.CommandState"> <variable name="myproject.view.input.active" priorityLevel="workbench"> </variable> And, finally, my CommandState class: public class CommandState extends AbstractSourceProvider { public final static String OUTPUT_VIEW = "myproject.view.input.active"; // then goes some others variables, i just skip them // .... public final static String [] ACTIONS = {OUTPUT_VIEW /*and all others variables*/}; public final static String ENABLED = "ENABLED"; public final static String DISENABLED = "DISENABLED"; private final Map <String, String> currentState = new HashMap <String, String> (); @Override public void dispose() { } @Override public String[] getProvidedSourceNames() { return ACTIONS; } @Override public Map <String, String> getCurrentState() { return currentState; } public void setEnabled(boolean enabled, String [] commands) { String value = enabled ? ENABLED : DISENABLED; for (String command : commands) { currentState.put(command, value); fireSourceChanged(ISources.WORKBENCH, command, value); } } } In my Login window, application checks user permissions, and enable or disable views, commands, etc. with setEnabled method of CommandState. For commands it works fine, they are enabling or disabling correctly. But when i try to disable view and open perspective, that contains that view (myproject.view.input), it opened without that view, but also throws exception: !STACK 1 org.eclipse.ui.PartInitException: Could not create view: myproject.view.input at org.eclipse.ui.internal.ViewFactory.createView(ViewFactory.java:158) I can show full stacktrace if anyone want. I tried to debug my application and before i open my perspective whith that view, i checked currentState of my CommandState source provider, and all seemes to be ok: all variables values are correct and myproject.view.input.active = DISABLED Can anyone say, why exception is thrown? Thanks for any help. Sorry for big post and bad language

    I would like a little help on configuring pptp so I can use my server as a vpn server since I have 10 ip's on it and I travel a lot so that would really help me and my partners.

    Hello All, I am trying to read some info from a text file by using windows command line, and save it to a variable just like "set info =1234" Below is the content of the txt file, actually I just need the revision number, and the location of it is always the same line 5, and from column 11 to 15. In the sample it's 1234, and I am wondering is there a way to save it to a variable in Dos command line. Thanks a lot! svninfo.txt: Path: .

  • var undefined = true;

    - by Andreas Grech
    I'm doing some experimenting with this malicious JavaScript line: var undefined = true; Every uninitialized variable in JavaScript has the value of undefined which is just a variable that holds the special value of 'undefined', so the following should execute the alert: var undefined = true, x; if (x) { alert('ok'); } But it doesn't, and my question is why? On further experimentation, I tried the following: var undefined = true, x = undefined; if (x) { alert('ok'); } This time, the alert is executed. So my question is...since in the first snippet x holds undefined (because it is not initialized), why didn't the alert execute? The strange thing is that when explicitly stating that x is undefined (x = undefined), the alert executed...

  • Can I pass an argument to a VBScript (vbs file launched with cscript)?

    - by Peter
    I have this script saved in "test.vbs": Set FSO = CreateObject("Scripting.FileSystemObject") Set File = FSO.OpenTextFile(workFolder &"\test.txt", 2, True) File.Write "testing" File.Close Set File = Nothing Set FSO = Nothing Set workFolder = Nothing When I run the script I want to pass the value of the "workFolder" variable. How can I do this? Can I do it? Something like "cscript test.vbs workFolder:'C:\temp\'" perhaps? Bonus question: Is it neccessary to clean up the passed variable with "Set workFolder = Nothing" or does VBSCript do that automatically when it terminates? Maybe "Set File = Nothing" and "Set FSO = Nothing" is unneccessary also? Please let me know if you know the answer to both these questions.

  • Marshal a list of objects from VB6 to C#

    - by Andrew
    I have a development which requires the passing of objects between a VB6 application and a C# class library. The objects are defined in the C# class library and are used as parameters for methods exposed by other classes in the same library. The objects all contain simple string/numeric properties and so marshaling has been relatively painless. We now have a requirement to pass an object which contains a list of other objects. If I was coding this in VB6 I might have a class containing a collection as a member variable. In C# I might have a class with a List member variable. Is it possible to construct a C# class in such a way that the VB6 application could populate this inner list and marshal it successfully? I don't have a lot of experience here but I would guess Id have to use an array of Object types.

  • Flexible argument list in LibreOffice Calc Macro

    - by Patru
    I want to write a function that geometrically links performance data which is usually provided as percentages, so the function will basically return (1+a)*(1+b)*(1+c)* … *(1+x)-1 This should be done using LibreOffice-calc and it should behave similarly to the regular sum function. As you may throw any number of arguments at sum I would like to be able to do the same with my alternative geoSum function but I am unable to find suitable documentation on handling a variable number of arguments with variable types (i.e. an arbitrary mix of numbers, cells and ranges). How would I have to specify the arguments to my LibreOffice-Basic function and how would I have to interpret it?

  • ruby on rails params injection

    - by Julien P.
    Hello everyone, I have a question about ruby on rails and the process of assigning variables using the params variable passed through a form class User attr_accessible :available_to_admins, :name end Let's say that I have a field that is only available to my admins. Assuming that you are not an admin, I am going to not display the available_to_admins input in your form. After that, when I want to save your data I'll just do a: User.update_attributes(params[:user]) If you are an admin, then no problem, the params[:user] is going to contain name and available_tu_admins and if you're not then only your name. Since the available_to_admins is an attr_accessible parameter, how should I prevent non admin users from being able to inject a variable containing the available_to_admins input with their new value?

  • Are these two functions overkill for sanitization?

    - by jpjp
    function sanitizeString($var) { $var = stripslashes($var); $var = htmlentities($var); $var = strip_tags($var); return $var; } function sanitizeMySQL($var) { $var = mysql_real_escape_string($var); $var = sanitizeString($var); return $var; } I got these two functions from a book and the author says that by using these two, I can be extra safe against XSS(the first function) and sql injections(2nd func). Are all those necessary? Also for sanitizing, I use prepared statements to prevent sql injections. I would use it like this: $variable = sanitizeString($_POST['user_input']); $variable = sanitizeMySQL($_POST['user_input']);

  • Regarding BigDecimal

    - by arav
    i do the below java print command for this double variable double test=58.15; When i do a System.out.println(test); and System.out.println(new Double(test).toString()); It prints as 58.15. When i do a System.out.println(new BigDecimal(test)) I get the below value 58.14999999999999857891452847979962825775146484375 I am able to understand "test" double variable value is internally stored as 58.1499999. But when i do the below two System.out.println i am getting the output as 58.15 and not 58.1499999. System.out.println(test); System.out.println(new Double(test).toString()); It prints the output as 58.15 for the above two. Is the above System.out.println statements are doing some rounding of the value 58.1499999 and printing it as 58.15?

  • To detect if the user is closing the IE browser apart from onunload event, as it is triggerred when

    - by AndAars
    hi, After being through numerous forums available on the net for last 5 days, I am still not able to completely track down the browser close event. My requirement is to generate a popup message, when user tries to close the browser. I have called my javascript function on body 'onbeforeunload' event. And I have hardcoded the conditions to check the mouse-coordinates for the red 'X' buton of browser, refresh, File-close or Alt-F4. My code works fine when browser window is Maximized, but fails if we shrink it after a limit. Please help me, if some body has already found the solution to a similar problem. Thank you. Aggregated Responses of OP Ok, just tell me if it is possible to detect if a user has clicked on the Refresh button of the browser. Also, Refresh can be triggered by Right-click - Refresh or Ctrl-R. My requirement is to make a variable false on Refresh. I am just able to do it on F5, but all other ways are still out of my reach. The same would be applied to Back buton. Hi ppl, Thanks for all who replied atleast. I have talked to my seniors regarding this and they have now understood and have compromised with the browser menu buttons. So now my task has become easy. Now, I am using a variable and making it true by default. As, I mentioned earlier I just have to catch the onbeforeunload and popup a message when user tries to leave. The message will not popup when user is navigating to other pages, as I have made the variable as false on all the links of my page using following piece of code: document.onclick = function() { //To check if user is navigating from the page by clicking on a hyperlink. if (event.srcElement.tagName == 'A') blnShowMsg = false; //To not popup the warning message else blnShowMsg = true; //To popup the warning message } In my case still the message is shown when user does Refresh, back or goes to any link in Favorites, etc. Thanks buddy, but I have already gone through that and didn't find much help there too. My seniors are not happy with that solution as putting a flag on evry link of my application is a complicated job and they fear of breaking the application. Any other suggestions would be appreciated. Thanks once again. Is there no one who can think of a solution here!!! where are all the experts???

  • Problem requesting a HTTPS with TCL

    - by Javier
    Hi Everybody, I'm trying to do the following request using TCL (OpenACS) http::register https 443 tls::socket set url "https://encrypted.google.com" set token [http::geturl $url -timeout 30000] set status [http::status $token] set answer [http::data $token] http::cleanup $token http::unregister https The problem is that when I read the $status variable I get "eof" and the $answer variable becomes empty. I tried enabling tls V.1 http::register https 443 [list tls::socket -tls1 1] and it works only for the site https://www.galileo.edu, but not for https://encrypted.google.com. The site what I'm trying to connect is https://graph.facebook.com/me/feed?access_token=... but it doesn't work. I used curl to retrieve the contents of the pages in HTTPS and it works, I have installed OpenSSL, so I can't see the problem, there is another way to do HTTPS connections with TCL?. I can't see if this is a problem of coding (maybe I'm registered wrong the https protocol) or maybe It is a bad configuration of my server. Hope somebody helps!! Thanks!

  • Ruby - Possible to pass a block as a param as an actual block to another function?

    - by Markus O'Reilly
    This is what I'm trying to do: def call_block(in_class = "String", &block) instance = eval("#{in_class}.new") puts "instance class: #{instance.class}" instance.instance_eval{ block.call } end # --- TEST EXAMPLE --- # This outputs "class: String" every time "sdlkfj".instance_eval { puts "class: #{self.class}" } # This will only output "class: Object" every time # I'm trying to get this to output "class: String" though call_block("String") { puts "class: #{self.class}" } On the line where it says "instance.instance_eval{ block.call }", I'm trying to find another way to make the new instance variable run instance eval on the block. The only way I can think of to get it to do that is to pass instance_eval the original block, not as a variable or anything, but as a real block like in the test example. Any tips?

  • Assembly stack persistency

    - by user246100
    Hello. I would like to know if after calling functions the data I have in the stack is persistent. Like, I would like to know if (assuming cdecl convention) can I do this (independently of function X and independently of optimizations): push 1 push 2 push 3 call X call X call X add 12 esp ? Also, let's say that before the calls I save the address of where the pushed values are in a global variable. Can I, inside X, alter the values it contain by acessing the global variable? Like, for some reason I want that in X I'm able to alter the values in stack so that the second and third call to X receive different values.

  • JavaScript function binding (this keyword) is lost after assignment

    this is one of most mystery feature in JavaScript, after assigning the object method to other variable, the binding (this keyword) is lost var john = { name: 'John', greet: function(person) { alert("Hi " + person + ", my name is " + this.name); } }; john.greet("Mark"); // Hi Mark, my name is John var fx = john.greet; fx("Mark"); // Hi Mark, my name is my question is: 1) what is happening behind the assignment? var fx = john.greet; is this copy by value or copy by reference? fx and john.greet point to two diferent function, right? 2) since fx is a global method, the scope chain contains only global object. what is the value of this property in Variable object?

  • static arrays defined with unspecified size, empty brackets?

    - by ahmadabdolkader
    For the C++ code fragment below: class Foo { int a[]; // no error }; int a[]; // error: storage size of 'a' isn't known void bar() { int a[]; // error: storage size of 'a' isn't known } why isn't the member variable causing an error too? and what is the meaning of this member variable? I'm using gcc version 3.4.5 (mingw-vista special) through CodeBlocks 8.02. On Visual Studio Express 2008 - Microsoft(R) C/C++ Optimizing Compiler 15.00.30729.01 for 80x86, I got the following messages: class Foo { int a[]; // warning C4200: nonstandard extension used : zero-sized array in struct/union - Cannot generate copy-ctor or copy-assignment operator when UDT contains a zero-sized array }; int a[]; void bar() { int a[]; // error C2133: 'a' : unknown size } Now, this needs some explaination too.

  • PHPMailer safe practices - Send escaped / sanitized variables or not ?

    - by FreekOne
    I'm using the PHPMailer-Lite class to build an email sending script and I'm not sure if I should use addslashses() on the $name variable when adding it to the constructor. If somebody's last name would be O'Riley (or any other name that contains characters which should normally be sanitized before handling) and I would send it unescaped, wouldn't it mess with the script/email sending ? Is it safe to send it unescaped ? As a side note, I would also like to avoid having my message body say "Hello, O\'Riley". Looking at the source, I saw that it only trims the whitespace and line ending (\r\n) characters from the received $name variable, so any advice on this would be more than welcome. Thank you all in advance !

  • I need to know what link is clicked, how do i get these variables with cherrypy?

    - by user291071
    Lets say I display 3 links, I want to accomplish 2 things, know which link is clicked, and record this choice in a list/pickle or txt file but also capture this variable in cherrypy so I can perform another action. How do I do this? Its been suggested that I use a query string which makes sense but I can't get the querystring variable to cherrypy to use for further actions. So would anyone have a simple code of cherrypy with lets say 2 pages and have one page display 2 links with a querystring in each and the second page able to get that value?
