• Visual Studio 2008 closes unexpectedly

  - by Jose

  I don't know if I can really get an answer to this question, but it really irks me and I would like to know if someone has an idea how to arrive to an answer. I have a pretty large solution in VS 2008 that maybe every week/every other week whenever I click properties to get to the project properties the IDE closes without warning. After that happens it will close EVERY time I try and view the properties. At that point I try and delete the .suo file, I resize the IDE, I close the tabs within the project, I restore default VS Settings(when I'm desperate). Eventually 20-30 minutes later I can actually view the properties. I haven't figured out exactly what fixes it, seems to be different every time. Once it's "fixed" I can't break it again so I can figure out what "fixed" it. This seems to be project specific, because I can view properties of other projects while this project is misbehaving. I guess my first question is, does VS log reasons for closing unexpectedly? Can I find out what the offending reason behind this is? The main frustration is I don't know that cause, nor the cure. Any ideas?

• problem with kCFSocketReadCallBack

  - by zp26

  Hello. I have a problem with my program. I created a socket with "kCFSocketReadCallBack. My intention was to call the "acceptCallback" only when it receives a string to the socket. Instead my program does not just accept the connection always goes into "startReceive" stop doing so and sometimes crash the program. Can anybody help? Thanks readSocket = CFSocketCreateWithNative( NULL, fd, kCFSocketReadCallBack, AcceptCallback, &context ); static void AcceptCallback(CFSocketRef s, CFSocketCallBackType type, CFDataRef address, const void *data, void *info) // Called by CFSocket when someone connects to our listening socket. // This implementation just bounces the request up to Objective-C. { ServerVistaController * obj; #pragma unused(address) // assert(address == NULL); assert(data != NULL); obj = (ServerVistaController *) info; assert(obj != nil); #pragma unused(s) assert(s == obj->listeningSocket); if (type & kCFSocketAcceptCallBack){ [obj acceptConnection:*(int *)data]; } if (type & kCFSocketAcceptCallBack){ [obj startReceive:*(int *)data]; } } -(void)startReceive:(int)fd { CFReadStreamRef readStream = NULL; CFIndex bytes; UInt8 buffer[MAXLENGTH]; CFStreamCreatePairWithSocket( kCFAllocatorDefault, fd, &readStream, NULL); if(!readStream){ close(fd); [self updateLabel:@"No readStream"]; } CFReadStreamOpen(readStream); [self updateLabel:@"OpenStream"]; bytes = CFReadStreamRead( readStream, buffer, sizeof(buffer)); if (bytes < 0) { [self updateLabel:(NSString*)buffer]; close(fd); } CFReadStreamClose(readStream); }

• Jquery Dialog - Is there a way to open it without registering it using .dialog?

  - by Raja

  This is my problem. I have a page with multiple tabs. I load those tabs dynamically and one of those tabs is a message container (mail). Every time I click a folder link (Inbox, Sent Mail etc) I reload just that tab alone with appropriate content. I use Jquery dialog to pick contacts and I have to load contacts everytime. Since I reload the whole tab content every time JQuery Dialog registers (or creates) the whole div content. To avoid this I did this: if ($("#ui-dialog-title-divContacts").length == 0) { //if dialog data is not created then make dialog $("#divContacts").dialog({ bgiframe: true, resizable: false, autoOpen: false, height: 600, width: 425, modal: true, overlay: { backgroundColor: '#000', opacity: 0.5 }, buttons: { Cancel: function () { //basically do nothing $(this).dialog("close"); }, 'Done': function () { $("#divTo").empty().html($("#divSelectedContacts").html()); $(this).dialog("close"); } } }); } I went to generated viewsource in FF and found that only one instance is being created. My problem now is it is not showing the dialog. Is there a way by which I can open this dialog without registering it. Any help is much appreciated.

• TCP/IP RST being sent differently in different browsers.

  - by Brian

  On Mac OS X (10.6), if I start a YouTube video download and pull the Ethernet cable for 5 or so seconds, then plug it back in, I get varying results depending on the browser. With Opera and Chrome, after I plug the cable back in the video continues to load. But with Safari and Firefox, it never does. Using Wireshark to look at the traffic, I found that Opera and Chrome simply ACK the first packet from YouTube after the cable has been plugged back in, but Safari and Firefox set the RST flag (0x4) in the TCP header and no more traffic follows. I can put a HUB in between the machine and the internet connection, the problem goes away and all four browsers continue loading the video when the cable is plugged back into the HUB. Again, looking at the Wireshark logs, it's evident that the machine doesn't see the Mulitcast connection close and there is simply a delay in the packets flowing through. So it seems that if Safari and Firefox sees a Multicast connection close, and then later see data on that same connection, they will send a RST. My question is why? What is the correct course of action, and why are 2/4 browsers doing it one way, while the other 2/4 are doing it another way? Is there somewhere in the code that I can see where this is happening in Firefox, for instance? Thank you very much.

• document.getElementById returns null for my drop-down select menu

  - by tucson

  I am trying to create a drop-down select menu with custom css (similar to the drop-down selection of language at http://translate.google.com/#). I have current html code: <ul id="Select"> <li> <select id="myId" onmouseover="mopen('options')" onmouseout="mclosetime()"> <div id="options" onmouseover="mcancelclosetime()" onmouseout="mclosetime()"> <option value="1" selected="selected">One</option> <option value="2">Two</option> <option value="3">Three</option> </div> </select> </li> </ul> and the Javascript: function mopen(id) { // cancel close timer mcancelclosetime(); // close old layer if(ddmenuitem) ddmenuitem.style.visibility = 'hidden'; // get new layer and show it ddmenuitem = document.getElementById(id); ddmenuitem.style.visibility = 'visible'; } But document.getElementById returns null. Though if I use the code with a div element that does not contain a select list the document.getElementById(id) returns proper div value. How do I fix this? or is there a better way to create drop-down select menu like http://translate.google.com ?

• SQL Server: Can you help me with this query?

  - by rlb.usa

  I want to run a diagnostic report on our MS SQL 2008 database server. I am looping through all of the databases, and then for each database, I want to look at each table. But, when I go to look at each table (with tbl_cursor), it always picks up the tables in the database 'master'. I think it's because of my tbl_cursor selection : SELECT table_name FROM information_schema.tables WHERE table_type = 'base table' How do I fix this? Here's the entire code: SET NOCOUNT ON DECLARE @table_count INT DECLARE @db_cursor VARCHAR(100) DECLARE database_cursor CURSOR FOR SELECT name FROM sys.databases where name<>N'master' OPEN database_cursor FETCH NEXT FROM database_cursor INTO @db_cursor WHILE @@Fetch_status = 0 BEGIN PRINT @db_cursor SET @table_count = 0 DECLARE @table_cursor VARCHAR(100) DECLARE tbl_cursor CURSOR FOR SELECT table_name FROM information_schema.tables WHERE table_type = 'base table' OPEN tbl_cursor FETCH NEXT FROM tbl_cursor INTO @table_cursor WHILE @@Fetch_status = 0 BEGIN DECLARE @table_cmd NVARCHAR(255) SET @table_cmd = N'IF NOT EXISTS( SELECT TOP(1) * FROM ' + @table_cursor + ') PRINT N'' Table ''''' + @table_cursor + ''''' is empty'' ' --PRINT @table_cmd --debug EXEC sp_executesql @table_cmd SET @table_count = @table_count + 1 FETCH NEXT FROM tbl_cursor INTO @table_cursor END CLOSE tbl_cursor DEALLOCATE tbl_cursor PRINT @db_cursor + N' Total Tables : ' + CAST( @table_count as varchar(2) ) PRINT N'' -- print another blank line SET @table_count = 0 FETCH NEXT FROM database_cursor INTO @db_cursor END CLOSE database_cursor DEALLOCATE database_cursor SET NOCOUNT OFF

• Showing Loading screen during REST service request in android app ?

  - by sat

  Currently here is what I am following, As soon as my app is launched, I have to send a request for REST service, It will take little time , so I thought of showing loading screen, In onCreate() of my Activity , first thing will be to show loading screen(progress dialog) , And I kick off the background Activity using AsyncTask , i.e. requesting for REST service and onPostexecute() I close the dialog and then I do setContentView(myxml); and update the UI . Can this approach be improved ? Problem which I faced was , Sometimes , Garbage collector may start(due to various reasons) and my app hangs at loading screen forever , because of Garbage collector , even request for REST service is not sent and because of it some wake up call comes and rest is disaster and Force close. But sometimes even ForceClose doesnot come fast , may be because of GC. so I cannot even go back and stuck in loading screen. Only thing which I can do at that point is to come back HOME. After that If I come back to my app its still loading , so definitely this approach seems to be a bad design. Whats the right approach ?

• global variables doesn't change value in Javascript

  - by user1856906

  My project is composed by 2 html pages: 1)index.html, wich contains the login and the registration form. 2)user_logged.html, wich contains all the features of a logged user. Now, what I want to do is a control if the user is really logged, to avoid the case where a user paste a url in the browser and can see the pages of another user. hours as now, if a user paste this url in the browser: www.user_loggato.html?user=x#profile is as if logged in as user x and this is not nice. My html pages both use js files that contains scripts. I decided to create a global variable called logged inizialized to false and change the variable to true when the login is succesfull. The problem is that the variable, remains false. here is the code: var logged=false; (write in the file a.js) while in the file b.js I have: function login() { //if succesfull logged=true; window.location.href = "user_loggato.html?user="+ JSON.parse(str).username + #profilo"; Now with some alerts I found that my variable logged is always false. Why? if I have not explained well or if there is not some information in order to respond to my question let me know.

• Dynamic table memory usage

  - by Dan

  I use a dynamic table: <html> <body> <button id="button">Build table</button> <div id="container"> <script type="text/javascript"> window.onload=function(){ var table = null; var row = "<tr><td>111111111111111111111111111111111111111111111111111111</td>" + "<td>222222222222222222222222222222222222222222222222222222</td>" + "<td>333333333333333333333333333333333333333333333333333333</td></tr>"; var data = null; for (var i = 0; i < 2000; i++){ data += row; } var obj = document.getElementById("button"); obj.onclick=function buildTable(){ document.getElementById("container").innerHTML = "<div><table><tbody>" + data + "</tbody></table></div>"; }; }; </script> </body> </html> Using chromes task manager, each time new data is loaded the memory usage increases considerably and doesn't go down, so after some time the app consumes a lot of memory and requires the browser to be closed. Is there any change in the code I can use to solve this or is it a browser side problem?

• Redirect requests only if the file is not found?

  - by ZenBlender

  I'm hoping there is a way to do this with mod_rewrite and Apache, but maybe there is another way to consider too. On my site, I have directories set up for re-skinned versions of the site for clients. If the web root is /home/blah/www, a client directory would be /home/blah/www/clients/abc. When you access the client directory via a web browser, I want it to use any requested files in the client directory if they exist. Otherwise, I want it to use the file in the web root. For example, let's say the client does not need their own index.html. Therefore, some code would determine that there is no index.html in /home/blah/www/clients/abc and will instead use the one in /home/blah/www. Keep in mind that I don't want to redirect the client to the web root at any time, I just want to use the web root's file with that name if the client directory has not specified its own copy. The web browser should still point to /clients/abc whether the file exists there or in the root. Likewise, if there is a request for news.html in the client directory and it DOES exist there, then just serve that file instead of the web root's news.html. The user's experience should be seamless. I need this to work for requests on any filename. If I need to, for example, add a new line to .htaccess for every file I might want to redirect, it rather defeats the purpose as there is too much maintenance needed, and a good chance for errors given the large number of files. In your examples, please indicate whether your code goes in the .htaccess file in the client directory, or the web root. Web root is preferred. Thanks for any suggestions! :)

• Need help with height 100% layout

  - by serg

  I am trying to build the following layout (file browser type of thing, left block would contain a list of files, right panel would contain selected file content): <------------- MENU -------------------> <--- LEFT ----><------- RIGHT ---------> <--- LEFT ----><------- RIGHT ---------> <--- LEFT ----><------- RIGHT ---------> <--- LEFT ----><------- RIGHT ---------> <--- LEFT ----><------- RIGHT ---------> <--- LEFT ----><------- RIGHT ---------> The page itself shouldn't have any scrollbars. Menu has 100% width and fixed height Left block has fixed width and 100% height. If content is taller - scroll bar appears inside the left block only. Right block contains <pre> element and takes the remaining width and 100% height. If content is wider or taller - scrollbar appears inside the right block only. This is what I have so far: http://jsbin.com/uqegi4/3/edit The problem is fixed menu height messes up 100% height calculation and all scrollbars inside left and right blocks appear at wrong time. I don't care about cross browser compatibility, only Chrome matters. Thanks.

• Excel VBA: Error Handling with Case Statement

  - by AME

  I am trying to validate a file that is uploaded by the user using the code below. The error handler checks the top row of the uploaded file for three specific column names. If one or more of the column names is not present, the program should return a prompt to the user notifying them which column(s) are missing from the file that they uploaded and then close the file. There are a couple issues with my current VBA code that I am seeking help with: The prompt doesn't specify which column(s) are missing to the user. The error handler is triggered even when all required columns are present in the uploaded file. Code: Sub getworkbook() ' Get workbook... Dim ws As Worksheet Dim filter As String Dim targetWorkbook As Workbook, wb As Workbook Dim Ret As Variant Set targetWorkbook = Application.ActiveWorkbook ' get the customer workbook filter = ".xlsx,.xls" caption = "Please select an input file " Ret = Application.GetOpenFilename(filter, , caption) If Ret = False Then Exit Sub Set wb = Workbooks.Open(Ret) On Error GoTo ErrorLine: 'Check for columns var1 = ActiveSheet.Range("1:1").Find("variable1", LookIn:=xlValues, LookAt:=xlWhole, MatchCase:=True).Column var2 = ActiveSheet.Range("1:1").Find("variable2", LookIn:=xlValues, LookAt:=xlWhole, MatchCase:=True).Column var3 = ActiveSheet.Range("1:1").Find("variable3", LookIn:=xlValues, LookAt:=xlWhole, MatchCase:=True).Column ErrorLine: MsgBox ("The selected file is missing a key data column, please upload a correctly formated file.")

• Avoiding duplicate objects in Java deserialization

  - by YGL

  I have two lists (list1 and list2) containing references to some objects, where some of the list entries may point to the same object. Then, for various reasons, I am serializing these lists to two separate files. Finally, when I deserialize the lists, I would like to ensure that I am not re-creating more objects than needed. In other words, it should still be possible for some entry of List1 to point to the same object as some entry in List2. MyObject obj = new MyObject(); List<MyObject> list1 = new ArrayList<MyObject>(); List<MyObject> list2 = new ArrayList<MyObject>(); list1.add(obj); list2.add(obj); // serialize to file1.ser ObjectOutputStream oos = new ObjectOutputStream(...); oos.writeObject(list1); oos.close(); // serialize to file2.ser oos = new ObjectOutputStream(...); oos.writeObject(list2); oos.close(); I think that sections 3.4 and A.2 of the spec say that deserialization strictly results in the creation of new objects, but I'm not sure. If so, some possible solutions might involve: Implementing equals() and hashCode() and checking references manually. Creating a "container class" to hold everything and then serializing the container class. Is there an easy way to ensure that objects are not duplicated upon deserialization? Thanks.

• How to send data from an opened window back to its opener in WPF.

  - by TravisPUK

  In WPF I have one window opening a second window that allows some data selections to occur on. Once the selections have been made I then want to submit/close the second/sub window and have the data pushed back to the opening/parent window. I can push data into the sub window from the parent via public properties, but have not worked out how to get it back the other way. Can anyone help please? The code I am using to open the window and set some properties is has follows: Dim wdwContacts As New appContacts() wdwContacts.selClientID = selClientID wdwContacts.selEmailToCCType = selEmailToCCType wdwContacts.pullToAddresses = txEmailTo.Text wdwContacts.pullCCAddresses = txEmailCC.Text wdwContacts.Owner = Me wdwContacts.WindowStartupLocation = Windows.WindowStartupLocation.CenterOwner wdwContacts.Show() The basis is that I have the first window as an email composition page that has a button that when clicked brings up a list of email contacts. It brings through any previously selected email addresses from the first window and auto selects them on the sub window/email list. If further selections are made on the email list, when the op clicks the done/submit/close button it pushes the new selection list back into the relevant TextBox on the first/parent window. Thanks

• Asp.Net 2 integrated sites How to Logout second site programatically.

  - by NBrowne

  Hi , I am working with an asp.net 2.0 site (call it site 1) which has an iframe in it which loads up another site (site2) which is also an asp.net site which is developed by our team. When you log onto site 1 then behind the scenes site 2 is also logged in so that when you click the iframe tab then this displays site 2 with the user logged in (to prevent the user from having to log in twice). The problem i have is that when a user logs out of site 1 then we call some cleanup methods to perform FormsAuthentication.SignOut and clean session variables etc but at the moment no cleanup is called when the user on site 2. So the issue is that if the user opens up Site 2 from within a browser then website 2 opens with the user still logged in which is undesired. Can anyone give me some guidance as to the best approach for this?? One possible approach i though of was just that on click of logout button i could do a call to a custom page on Site 2 which would do the logout. Code below HttpWebRequest request; request = ((HttpWebRequest)(WebRequest.Create("www.mywebsite.com/Site2Logout.aspx"))); request.Method = "POST"; HttpCookie cookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName]; Cookie authenticationCookie = new Cookie( FormsAuthentication.FormsCookieName, cookie.Value, cookie.Path, HttpContext.Current.Request.Url.Authority); request .CookieContainer = new CookieContainer(); request .CookieContainer.Add(authenticationCookie); response.GetResponse(); Problem i am having with this code is that when i run it and debug on Site 2 and check to see if the user is Authenticated they are not which i dont understand because if i open browser and browse to Site 2 i am Still authenticated. Any ideas , different direction to take etc ??? Please let me know if you need any more info or if i something i have said dosent make sense. Thanks

• How to find whole graph coverage path in dynamic state-flow diagram?

  - by joseph

  Hello, As I've been researching algorithms for path finding in graph, I found interesting problem. Definition of situation: 1)State diagram can have p states, and s Boolean Fields, and z Int Fields 2)Every state can have q ingoing and r outgoing transitions, and h Int fields (h belongs to z - see above) 3)Every transition can have only 1 event, and only 1 action 4)every action can change n Boolean Fields, and x Int Fields 5)every event can have one trigger from combination of any count of Boolean Fields in diagram 6)Transition can be in OPEN/CLOSED form. If the transition is open/closed depends on trigger2 compounded from 0..c Boolean fields. 7) I KNOW algorithm for finding shortest paths from state A to state B. 8) I KNOW algorithm for finding path that covers all states and transitions of whole state diagram, if all transitions are OPEN. Now, what is the goal: I need to find shortest path that covers all states and transitions in dynamically changing state diagram described above. When an action changes some int field, the algorithm should go through all states that have changed int field. The algorithm should also be able to open and close transition (by going through transitions that open and close another transitions by action) in the way that the founded path will be shortest and covers all transitions and states. Any idea how to solve it? I will be really pleased for ANY idea. Thanks for answers.

• Client Side Only Cookies

  - by Mike Jones

  I need something like a cookie, but I specifically don't want it going back to the server. I call it a "client side session cookie" but any reasonable mechanism would be great. Basically, I want to store some data encrypted on the server, and have the user type a password into the browser. The browser decrypts the data with the password (or creates and encrypts the data with the password) and the server stores only encrypted data. To keep the data secure on the server, the server should not store and should never receive the password. Ideally there should be a cookie session expiration to clean up. Of course I need it be available on multiple pages as the user walks through the web site. The best I can come up with is some sort of iframe mechanism to store the data in javascript variables, but that is ugly. Does anyone have any ideas how to implement something like this? FWIW, the platform is ASP.NET, but I don't suppose that matters. It needs to support a broad range of browsers, including mobile. In response to one answer below, let me clarify. My question is not how to achieve the crypto, that isn't a problem. The question is where to store the password so that it is persistent from page to page, but not beyond a session, and in such a way that the server doesn't see it.

• How can I set/store cookie when anchor clicked

  - by Unaverage Guy

  I am trying to use Cookie so that a default style OR a specific style is applied in reference to the anchor tag clicked, even when the browser is closed/reopen. So if the user clicked the second link, close or refresh the browser and reopen, than the style should still be active, if it is their first time the default should apply. This is a little over my turf. Here is the HTML: <a id="default" href="#/">Default Style</a> <a id="style2" href="#/">Style 2</a> <a id="style3" href="#/">Style 3</a> <ol> <li><span>Hello World</span></li> </ol> JQuery: (Compliments of StackOverflow) <script type="text/javascript"> $('#default').on('click',function(){ $('ol li span').removeClass(function() { return $(this).attr('class'); }).addClass('default'); }); $('#style2').click(function(){ $('ol li span').removeClass(function() { return $(this).attr('class'); }).addClass('style2'); }); $('#style3').click(function(){ $('ol li span').removeClass(function() { return $(this).attr('class'); }).addClass('style3'); }); </script> CSS: <style type="text/css"> .default{ color: #333; } .style2{ color: #999; } .style3{ color: #800; } </style>

• How to validate DataReader is actually closed using FxCop custom rule?

  - by tanmay

  I have written couple of custom rules in for FxCop 1.36. I have written code to find weather an opened DataReader is closed or not. But it does not check which DataReader object is calling the Close() method so I can't be sure if all opened DataReader objects are closed!! 2nd: If I am a DataReader in an 'if/else' like if 1=2 dr = cmd.ExecuteReader(); else dr = cmd2.ExecuteReader(); end if In this case it will search for 2 DataReader objects to be closed. I am putting my code for more clarity. public override ProblemCollection Check(Member member) { Method method = member as Method; int countCatch =0; int countErrLog = 0; Instruction objInstr = null; if (method != null) { for (int i = 0; i < method.Instructions.Count; i++) { objInstr = method.Instructions[i]; if (objInstr.Value != null) { if (objInstr.Value.ToString() .Contains("System.Data.SqlClient.SqlDataReader")) { countCatch += 1; } if (countCatch>0) { if (objInstr.Value.ToString().Contains( "System.Data.SqlClient.SqlDataReader.Close")) { countErrLog += 1; } } } } } if (countErrLog!=countCatch) { Resolution resolu = GetResolution(new string[] { method.ToString() }); Problems.Add(new Problem(resolu)); } return Problems; }

• TortoiseSVN Error: "OPTIONS of 'https://...' could not connect to server (...)"

  I'm trying to setup a new computer to synchronize with my SVN repository that's hosted with cvsdude.com. I get this error: Here's what I did (these have worked in the past): Downloaded and installed TortoiseSVN Created a new folder C:\aspwebsite Right-clicked, chose SVN Checkout... Entered the following information, clicked OK: URL of repository: https://<reponame>-svn.cvsdude.com/aspwebsite Checkout directory: C:\aspwebsite Checkout depth: Fully recursive Omit externals: Unchecked Revision: HEAD revision Got TortoiseSVN error: OPTIONS of 'https://<reponame>-svn.cvsdude.com/aspwebsite': could not connect to server (https://<reponame>-svn.cvsdude.com) Rather than getting the error, TortoiseSVN should have asked for my username and password and then downloaded about 90MB. Why can't I checkout from my Subversion repository? Kent Fredric wrote: Either their security certificate has expired, or their hosting is broken/down. Contact CVSDude and ask them whats up. It could also be a timeout, because for me their site is exhaustively slow.. It errors after only a couple seconds. I don't think it's a timeout. Matt wrote: Try visiting https://[redacted]-svn.cvsdude.com/aspwebsite and see what happens. If you can visit it in your browser, you ought to be able to get the files in your SVN client and we can work from there. If it fails, then there's your answer. I can access the site in a web browser.

• Auto Submitting a form (cURL)

  - by cast01

  Im writing a form to post data off to paypal, and this works fine, i create the form with hidden fields and then have a submit button that submits everything to paypal. However, when the user clicks that button, there is more that i want to do, for example change their cart status in the database. So, i want to be able to execute some code when they click submit and then post the data to paypal. I dont want to use javascript for this. My method at the moment is using cURL, the form posts back to the current page, i then check for $_POST data, do my other commands like updating the status of the cart, and then create a curl command, and post the form data to paypal. Now, it gets posted successfully, but the browser doesnt go off to paypal. At first i was just retirieving the result in a string and then echoing it out and i could see that the post was successful, then i set CURLOPT_FOLLOWLOCATION to 1 assuming this would let the browser go off to paypal but it doesnt, what it seems to do is grab some stuff from paypal and put it on my page. Is using cURL the right thing for this? and if so, how do i get round this problem? I want to stay away from javascript for this as only users with javascript enabled would have their cart updated. The code im using for curl is below, the post_data is an array i created and then read key-value pairs into post_string. //Set cURL Options curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30); curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"); curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, false); curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($curl_connection, CURLOPT_MAXREDIRS, 20); //Set Data to be Posted curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string); //Execute Request curl_exec($curl_connection);

• JNA Passing Structure By Reference Help

  - by tyeh26

  Hi all, I'm trying to use JNA to talk over a USB device plugged into the computer. Using Java and a .dll that was provided to me. I am having trouble with the Write function: C code: typedef struct { unsigned int id; unsigned int timestamp; unsigned char flags; unsigned char len; unsigned char data[16]; } CANMsg; CAN_STATUS canplus_Write( CANHANDLE handle, //long CANMsg *msg ); Java Equivalent: public class CANMsg extends Structure{ public int id = 0; public int timestamp = 0; public byte flags = 0; public byte len = 8; public byte data[] = new byte[16]; } int canplus_Write(NativeLong handle, CANMsg msg); I have confirmed that I can open and close the device. The close requires the NativeLong handle, so i am assuming that the CANMsg msg is the issue here. I have also confirmed that the device works when tested with C only code. I have read the the JNA documentation thoroughly... I think. Any pointers. Thanks all.
