  • .NET assembly cache / ngen / jit image warm-up and cool-down behavior

    - by Mike Jiang
    Hi, I have an Input Method (IME) program built with C#.NET 2.0 DLL through C++/CLI. Since an IME is always attaching to another application, the C#.NET DLL seems not able to avoid image address rebasing. Although I have applied ngen to create a native image of that C#.NET 2.0 DLL and installed it into Global Assembly Cache, it didn't improved much, approximately 12 sec. down to 9 sec. on a slow PIII level PC. Therefore I uses a small application, which loads all the components referenced by the C#.NET DLL at the boot up time, to "warm up" the native image of that DLL. It works fine to speed up the loading time to 0.5 sec. However, it only worked for a while. About 30 min. later, it seems to "cool down" again. Is there any way to control the behavior of GAC or native image to be always "hot"? Is this exactly a image address rebasing problem? Thank you for your precious time. Sincerely, Mike

  • How to send set of data for Ajax call from jquery with php at the serverside?

    - by Vinodtiru
    I basically have to do a update of a record. I have a set of controls like textbox, list box, radio button etc. Then i have a button on click of which i need to carry all the updated data into mysql database with a ajax request without page refresh. I am using the php with codeigniter as my serverside code. On client side i am able to send the ajax request like $(document).ready(function(){ $('#users_menu').click( function(){ $('#tempdiv').load('http://localhost//web1/index.php/c1',null); } ); }); In the above code the request is placed to a server side php page where i am not able to read the values of the control values (values of textbox, listbox etc). Now this means i should be sending the list with the request. But i am not aware of how to send this request. Please help me with some details of how to send the list of values or is it possible to read the vaules some how in the serverside php code. For your information i am using codeigniter with my php. Any kind of help is appreciated. Thanks and Regards VinodT.

  • Async Load JavaScript Files with Callback

    - by Gcoop
    Hi All, I am trying to write an ultra simple solution to load a bunch of JS files asynchronously. I have the following script below so far. However the callback is sometimes called when the scripts aren't actually loaded which causes a variable not found error. If I refresh the page sometimes it just works because I guess the files are coming straight from the cache and thus are there quicker than the callback is called, it's very strange? var Loader = function () { } Loader.prototype = { require: function (scripts, callback) { this.loadCount = 0; this.totalRequired = scripts.length; this.callback = callback; for (var i = 0; i < scripts.length; i++) { this.writeScript(scripts[i]); } }, loaded: function (evt) { this.loadCount++; if (this.loadCount == this.totalRequired && typeof this.callback == 'function') this.callback.call(); }, writeScript: function (src) { var self = this; var s = document.createElement('script'); s.type = "text/javascript"; s.async = true; s.src = src; s.addEventListener('load', function (e) { self.loaded(e); }, false); var head = document.getElementsByTagName('head')[0]; head.appendChild(s); } } Is there anyway to test that a JS file is completely loaded, without putting something in the actual JS file it's self, because I would like to use the same pattern to load libraries out of my control (GMaps etc). Invoking code, just before the tag. var l = new Loader(); l.require([ "ext2.js", "ext1.js"], function() { var config = new MSW.Config(); Refraction.Application().run(MSW.ViewMapper, config); console.log('All Scripts Loaded'); }); Thanks for any help.

  • PGP Encrypt from C# using GnuPG

    - by Kishore
    Hello All, I'm trying to encrypt a incoming document in C#, and I'm using GnuPG with input redirection. I need to use -se(sign and encrypt) in a single step, which requires entering passphrase. But for some reason, input redirection is not working. Appreciate your help. Control is going to else block. I'm not sure if there is deadlock or child process(gpg.exe) waiting for the input. pgpproc = new Process(); pgpproc.StartInfo.FileName = exeFilePath; pgpproc.StartInfo.RedirectStandardOutput = false; pgpproc.StartInfo.RedirectStandardInput = true; pgpproc.StartInfo.UseShellExecute = false; pgpproc.StartInfo.Arguments = "-a -o C:\PGPStaging\output.pgp -se -r recipientID C:\PGPStaging\input.txt"; pgpproc.StartInfo.CreateNoWindow = true; pgpproc.Start(); StreamWriter myStreamWriter = pgpproc.StandardInput; myStreamWriter.Write("*****"); myStreamWriter.Close(); if (pgpproc.WaitForExit(waittime)) { //success } else { //failure pgpproc.Kill(); pgpproc.WaitForExit(); } `

  • Custom HTTPHandler causing caching or session issues?

    - by Jan de Jager
    So i have a custom CMS running under .Net 3.5 written entirely in c#. The engine is optimized to render for mobile devices, but also server to normal web browsers. It also supports cookieless sessions. Great... I've chosen not to cache anything (including browser data) in order to control the rendering completely from data. This has been all good until lately. The engine implements a basic login function that simply logs the user state within a session object. The behavior is rather strange. User will click through the site no problem. Then login. The login will either go through successfully or just redisplay the login screen, suggesting a cached page being returned or redisplayed... If the login is successful the concurrent page hits will switch arbitrarily between logged in and logged out state... Also suggesting either the session state is not accessible or a cached page being returned. I have debugged the hell out of the thing.... including using fiddler and the like. When debugging the behavior disappears. Huh? One of the sites running on the engine is http://www.wiseguy.mobi (sorry customized for South Africa, so you'll probably not be able to get the password Text Message)!

  • Looping Redirect with PyFacebook and Google App Engine

    - by Nick Gotch
    I have a Python Facebook project hosted on Google App Engine and use the following code to handle initialization of the Facebook API using PyFacebook. # Facebook Initialization def initialize_facebook(f): # Redirection handler def redirect(self, url): logger.info('Redirecting the user to: ' + url) self.response.headers.add_header("Cache-Control", "max-age=0") self.response.headers.add_header("Pragma", "no-cache") self.response.out.write('<html><head><script>parent.location.replace(\'' + url + '\');</script></head></html>') return 'Moved temporarily' auth_token = request.params.get('auth_token', None) fbapi = Facebook(settings['FACEBOOK_API_KEY'], settings['FACEBOOK_SECRET_KEY'], auth_token=auth_token) if not fbapi: logger.error('Facebook failed to initialize') if fbapi.check_session(request) or auth_token: pass else: logger.info('User not logged into Facebook') return lambda a: redirect(a, fbapi.get_login_url()) if fbapi.added: pass else: logger.info('User does not have ' + settings['FACEBOOK_APP_NAME'] + ' added') return lambda a: redirect(a, fbapi.get_add_url()) # Return the validated API logger.info('Facebook successfully initialized') return lambda a: f(a, fbapi=fbapi) I'm trying to set it up so that I can drop this decorator on any page handler method and verify that the user has everything set up correctly. The issue is that when the redirect handler gets called, it starts an infinite loop of redirection. I tried using an HTTP 302 redirection in place of the JavaScript but that kept failing too. Does anyone know what I can do to fix this? I saw this similar question but there are no answers.

  • Using a4j:support 's onchange event with h:selectOneMenu

    - by user339637
    <h:selectOneMenu id="selectOneMenu" value="#{Bean1.val1}" > <f:selectItems value="#{Bean1.selectItems}"/> <a4j:support event="onchange" action="#{Bean1.onSelectOneMenuChange}" reRender="textbox1 , textbox2 , textbox3, textbox4" /> </h:selectOneMenu> <h:inputText id="textbox1" value="#{Bean1.textbox1}"> </h:inputText> <h:inputText id="textbox2" value="#{Bean1.textbox2}"> </h:inputText> <h:inputText id="textbox3" value="#{Bean1.textbox3}"> </h:inputText> <h:inputText id="textbox4" value="#{Bean1.textbox4}"> </h:inputText> Bean1.onSelectOneMenuChange() will change the value of Bean1.textbox1 , Bean1.textbox2,Bean1.textbox3 and Bean1.textbox4 depending on the value selected (Bean1.val1) .Sometimes , it will change all the textbox value and sometimes it will only changes some textbox value. When users change the value in the "selectOneMenu" drop down list control , the JSF framework will not call the update model values phase but call the Bean1.onSelectOneMenuChange() directly. After that , the all the textbox are reRender. Because the update model values phase is not called , the values entered by the user is never set the the Bean1 and the original value is shown in the textbox after reRender . So I want to ask: How can I manually call the update model values phase inside Bean1.onSelectOneMenuChange() ?How can I get the value input input by the users inside Bean1.onSelectOneMenuChange() and set it to the corresponding fields of the Bean1 ? 2.Another approach is that only reRender those textbox whose values are updated inside the Bean1.onSelectOneMenuChange() .However , there are many cases . For example , a value will change all the textbox value and a values may only change some textbox value.How can I reRender conditionally ? What method is more prefer for maintainability?

  • Winforms: Attempted to read or write protected memory. This is often an indication that other memory is corrupt

    - by mamcx

  • Integrating Dynamics CMS with Sharepoint ASCX SecurityException Issue

    - by Gavin
    Hi, I've an ASCX control (WebParts aren't used in this solution) which interrogates CMS 4's data via the API provided by Microsoft.Crm.Sdk and Microsoft.Crm.SdkTypeProxy. The solution works until it's deployed to Sharepoint. Initially I received the following error: [SecurityException: That assembly does not allow partially trusted callers.] MyApp.SharePoint.Web.Applications.MyAppUtilities.RefreshUserFromCrm(String login) +0 MyApp.SharePoint.Web.Applications.MyApp_LoginForm.btnLogin_Click(Object sender, EventArgs e) +30 System.Web.UI.WebControls.Button.OnClick(EventArgs e) +111 Then I tried wrapping the calling code in the ASCX with SPSecurity.RunWithElevatedPrivileges: SPSecurity.RunWithElevatedPrivileges(delegate() { // FBA user may not exist yet or require refreshing MyAppUtilities.RefreshUserFromCrm(txtUser.Text); }); But this resulted in the following error: [SecurityException: Request for the permission of type 'Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' failed.] MyApp.SharePoint.Web.Applications.MyApp_LoginForm.btnLogin_Click(Object sender, EventArgs e) +0 System.Web.UI.WebControls.Button.OnClick(EventArgs e) +111 When I elevate the trust level in the Sharepoint site to full everything works fine, however I need to come up with a solution that uses minimal trust (or a customised minimal trust). I'm also trying to stay clear of adding anything to the GAC. Any ideas? I assume the issue is occuring when trying to call functionality from Microsoft.Crm.* Thanks in advance for any help anyone can provide. Cheers, Gavin

  • vbCrLf in Multiline TextBox shows up only when .Trim() is called

    - by Brandon Montgomery
    I have an ASP TextBox with TextMode set to MultiLine. I'm having problems with preserving the vbCrLf characters when a user tries to put line breaks into the text. When a button on the page is pressed, I'm taking the text from the control, trimming it using String.Trim, and assigning that value to a String property on an object (which, in turn assigns it to a private internal String variable on the object). The object then takes the value from the private internal variable and throws it into the database using a stored procedure call (the SP parameter it is put into is an nvarchar(4000)). ASPX Page: <asp:UpdatePanel ID="UpdatePanel2" runat="server" RenderMode="Inline" UpdateMode="Conditional" ChildrenAsTriggers="true"> <ContentTemplate> <!-- some other controls and things --> <asp:TextBox TextMode="MultiLine" runat="server" ID="txtComments" Width="100%" Height="60px" CssClass="TDTextArea" Style="border: 0px;" MaxLength="2000" /> <!-- some other controls and things --> </ContentTemplate> </asp:UpdatePanel> code behind: ProjectRequest.StatusComments = txtComments.Text.Trim object property: Protected mStatusComments As String = String.Empty Property StatusComments() As String Get Return mStatusComments.Trim End Get Set(ByVal Value As String) mStatusComments = Value End Set End Property stored proc call: Common.RunSP(mDBConnStr, "ProjectStatusUpdate", _ Common.MP("@UID", SqlDbType.NVarChar, 40, mUID), _ Common.MP("@ProjID", SqlDbType.VarChar, 40, mID), _ Common.MP("@StatusID", SqlDbType.Int, 8, mStatusID), _ Common.MP("@Comments", SqlDbType.NVarChar, 4000, mStatusComments), _ Common.MP("@PCTComp", SqlDbType.Int, 4, 0), _ Common.MP("@Type", Common.TDSqlDbType.TinyInt, 1, EntryType)) Here's the strangest part. When I debug the code, if I type "test test" (without the quotes) into the comments text box, then click the save button and use the immediate window to view the variable values as I step through, here is what I get: ?txtComments.Text "test test" ?txtComments.Text.Trim "test test" ?txtComments.Text(4) " "c ?txtComments.Text.Trim()(4) " "c Anyone have a clue as to what's going on here?

  • WPF - Setting usercontrol width using triggers and mouseenter event

    - by BigBadJock
    I have a wrap panel full of usercontrols. When I hover the mouse over a usercontrol I want it to expand to show more details. Some stripped down sample code: <UserControl x:Class="WPFTestBed.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <UserControl.Resources> </UserControl.Resources> <UserControl.Triggers> <EventTrigger RoutedEvent="Mouse.MouseEnter"> <EventTrigger.Actions> <Setter TargetName="WPFTestBed.UserControl1" Property="Control.Width" Value="200"/> </EventTrigger.Actions> </EventTrigger> </UserControl.Triggers> <Grid Height="95" Width="123"> <Button Height="23" HorizontalAlignment="Left" Margin="17,30,0,0" Name="button1" VerticalAlignment="Top" Width="75">Button</Button> </Grid> </UserControl> I would appreciate it if someone could point out where I'm going wrong, and set me down the correct path. Ideally, I want the usercontrol to delay for x seconds when there is a mouseover, before expanding and showing the extra details.

  • Deploying software on compromised machines

    - by Martin
    I've been involved in a discussion about how to build internet voting software for a general election. We've reached a general consensus that there exist plenty of secure methods for two way authentication and communication. However, someone came along and pointed out that in a general election some of the machines being used are almost certainly going to be compromised. To quote: Let me be an evil electoral fraudster. I want to sample peoples votes as they vote and hope I get something scandalous. I hire a bot-net from some really shady dudes who control 1000 compromised machines in the UK just for election day. I capture the voting habits of 1000 voters on election day. I notice 5 of them have voted BNP. I look these users up and check out their machines, I look through their documents on their machine and find out their names and addresses. I find out one of them is the wife of a tory MP. I leak 'wife of tory mp is a fascist!' to some blogger I know. It hits the internet and goes viral, swings an election. That's a serious problem! So, what are the best techniques for running software where user interactions with the software must be kept secret, on a machine which is possibly compromised?

  • Gmail IMAP OAuth for desktop clients

    - by Sabya
    Recently Google announced that they are supporting OAUth for Gmail IMAP/SMTP. I browsed through their multiple documentations, but still I am confused about if they support OAuth for installed applications. 1. In this documentation they say: Note: Though the OAuth protocol supports the desktop/installed application use case, Google only supports OAuth for web applications. But they also have a document for OAuth for installed applications. 2. When I read the OAuth specification pointed by them, it says (in section 11.7): In many applications, the Consumer application will be under the control of potentially untrusted parties. For example, if the Consumer is a freely available desktop application, an attacker may be able to download a copy for analysis. In such cases, attackers will be able to recover the Consumer Secret used to authenticate the Consumer to the Service Provider. Also I think the disclaimer in point 1 above is about Google Data APIs, and surely IMAP/SMTP is not a part of them. I understand that for installed applications I can have a setup like: Have a small web-app at say example.com for my application. This web-app talks to Google gets the access token. The installed application talks to example.com only to get the access token. Installed application then talks to Google with the access token. I am now confused. Is this the only way?

  • SCM for Xcode?

    - by Gregor
    I am developing an application for the Mac as a small team (me + another person) effort. We are located in different cities, and have started to see the need for solid source control management. None of us have any experience with this, and both of us are relatively new to Cocoa/Obj-C/Xcode (but do have C knowledge). Does anyone have any recommendations as to which SCM system to choose? I understand that a lot of people are using Subversion, which is also supported in Xcode 3.1. Does anyone have experience with using Subversion through Xcode? Or is it a better option to chose a stand alone GUI alternative, such as Versions? Grateful for any input on this. Gregor Tomasevic, Sweden Update/personal experiences: Since this post, we have tried Versions and Cornerstone (both of which are SVN GUI-clients), as well as Xcodes built-in support for SVN. We were not particularly pleased with Versions, which seemed to have some problems with committing unversioned files/build files. The built-in SVN support in Xcode works quite well, although it probably has limitations that we have still not run into. Cornerstone is both simple to use and powerful, and does not seem to suffer from the problems we encountered with Versions. So far, we have just tried committing, updating repo, checking out latest/previous versions of our files and worked some with file comparison. It might be a whole different ball game once you start working extensively with branching, an area which we have been told both these GUI clients might have some weaknesses in. For what it's worth (and with only days of evaluation) Cornerstone seems to be a somewhat better alternative, although for simpler SCM, Xcode works well too. Thanks for all the comments.

  • Process.CloseMainWindow() not working

    - by gehho
    I start the Windows On-Screen-Keyboard like that: s_onScreenKeyboard = new Process(); s_onScreenKeyboard.StartInfo = new ProcessStartInfo("osk.exe"); s_onScreenKeyboard.EnableRaisingEvents = true; s_onScreenKeyboard.Exited += new EventHandler(s_onScreenKeyboard_Exited); s_onScreenKeyboard.Start(); This works fine, but when I try to stop it using the following code, it does nothing: s_onScreenKeyboard.CloseMainWindow(); if (!s_onScreenKeyboard.HasExited) { if (!s_onScreenKeyboard.WaitForExit(1000)) { s_onScreenKeyboard.Close(); //s_onScreenKeyboard.Kill(); } } When uncommenting s_onScreenKeyboard.Kill(); it is closed, but the problem is that osk.exe obviously uses another process called "msswchx.exe" which is not closed if I simply kill the OSK process. This way, I would end up with hundreds of these processes which is not what I want. Another strange thing is that the CloseMainWindow() call worked at some time, but then it suddenly did not work anymore, and I do not remember what has changed. Any ideas? Background: I am implementing an On-Screen-Keyboard for my application because it should work with a touchscreen. It is important that the keyboard layout matches the layout which is configured in Windows since the application will be shipped to many different countries. Therefore, instead of implementing a custom keyboard control with approx. 537 keyboard layouts (exaggerating a little here...), I wanted to utilize the Windows built-in On-Screen-Keyboard which adapts to the selected keyboard layout automatically, saving a lot of work for me.

  • Sharepoint OLE DB - field not updateable

    - by Pandincus
    I need to write a simple C# .NET application to retrieve, update, and insert some data in a Sharepoint list. I am NOT a Sharepoint developer, and I don't have control over our Sharepoint server. I would prefer not to have to develop this in a proper sharepoint development environment simply because I don't want to have to deploy my application on the Sharepoint server -- I'd rather just access data externally. Anyway, I found out that you can access Sharepoint data using OLE DB, and I tried it successfully using some ADO.NET: var db = DatabaseFactory.CreateDatabase(); DataSet ds = new DataSet(); using (var command = db.GetSqlStringCommand("SELECT * FROM List")) { db.LoadDataSet(command, ds, "List"); } The above works. However, when I try to insert: using (var command = db.GetSqlStringCommand("INSERT INTO List ([HeaderName], [Description], [Number]) VALUES ('Blah', 'Blah', 100)")) { db.ExecuteNonQuery(command); } I get this error: Cannot update 'HeaderName'; field not updateable. I did some Googling and apparently you cannot insert data through OLE DB! Does anyone know if there are some possible workarounds? I could try using Sharepoint Web Services, but I tried that initially and was having a heck of a time authenticating. Is that my only option?

  • Configuration Error ASP.NET password format specified is invalid

    I am getting the above error in IIS 6.0 now when I browse my C# / SQL web application. This was built in VS 2008 and SS 2008 on a 32-bit XP OS.

  • How do you display a list of images, from a folder on hard drive, on ASP.NET website?

    - by Jordan S
    I am trying to make a simple photo gallery website. Using ASP.NET and C#. Right now I don't have a server set up but I am just using the development one that Visual Studio Starts when you make a website project and run it. I have a folder on my hard drive that contains an unknown number of images. I want to write a piece of code that will go through each image and add them to the default webpage. I have tried this code but it doesn't work. What am I doing wrong? Should I be using a ListView control or a DataView or something like that? Do I need to add a virtual directory in order to access the images? If so, how do I to that on this test server? ALSO, how do I set the position and alignment of these pictures? For example, how would I make it so that the pictures are in a line vertically and centered on the webpage? protected void Page_Load(object sender, EventArgs e) { string[] filesindirectory = Directory.GetFiles(@"C:\Users\Jordan\Desktop\Web Images"); int i = 1; foreach (string s in filesindirectory) { Image img = new Image(); img.ID = "image" + i.ToString(); img.ImageUrl = s; img.Visible = true; Page.Controls.Add(img); i++; } }

  • Application Errors vs User Errors in PHP

    - by CogitoErgoSum
    So after much debate back and forth, I've come up with what I think may be a valid plan to handle Application/System errors vs User Errors (I.e. Validation Issues, Permission Issues etc). Application/System Errors will be handled using a custom error handler (via set_error_handler()). Depending on the severity of the error, the user may be redirected to a generic error page (I.e. Fatal Error), or the error may simply be silently logged (i.e E_WARNING). These errors are ones most likely caused by issues outside the users control (Missing file, Bad logic, etc). The second set of errors would be User Generated ones. These are the ones may not automatically trigger an error but would be considered one. In these cases i"ve decided to use the trigger_error() function and typically throw a waning or notice which would be logged silently by the error handler. After that it would be up to the developer to then redirect the user to another page or display some sort of more meaningful message to the user. This way an error of any type is always logged, but user errors still allow the developer freedom to handle it in their own ways. I.e. Redirect them back to their form with it fully repopulated and a message of what went wrong. Does anyone see anything wrong with this, or have a more intuitive way? My approach to error handling is typically everyone has their own ways but there must be a way instituted.

  • Reading binary data from serial port using Dejan TComport Delphi component

    - by johnma
    Apologies for this question but I am a bit of a noob with Delphi. I am using Dejan TComport component to get data from a serial port. A box of equipment connected to the port sends about 100 bytes of binary data to the serial port. What I want to do is extract the bytes as numerical values into an array so that I can perform calculations on them. TComport has a method Read(buffer,Count) which reads DATA from input buffer. function Read(var Buffer; Count: Integer): Integer; The help says the Buffer variable must be large enough to hold Count bytes but does not provide any example of how to use this function. I can see that the Count variable holds the number of bytes received but I can't find a way to access the bytes in Buffer. TComport also has a methord Readstr which reads data from input buffer into a STRING variable. function ReadStr(var Str: String; Count: Integer): Integer; Again the Count variable shows the number of bytes received and I can use Memo1.Text:=str to display some information but obviously Memo1 has problems displaying the control characters. I have tried various ways to try and extract the byte data from Str but so far without success. I am sure it must be easy. Here's hoping.

  • Is this error caused by a 64-bit library being accessed by a Java program running in a 32-bit JVM?

    - by Mike
    I'm trying to create a simple Java app that uses JNI to call some native functions. I've followed the examples in the JNI Programming Guide and can't seem to get them to work. I have the following Hello World program, written in Java: class HelloWorld { private native void print(); public static void main(String [] args) { new HelloWorld().print(); } static { System.load("/home/mike/Desktop/libHelloWorld.so"); } } I compile it using javac HelloWorld.java, just like normal. Then I run javah -jni HelloWorld, and finally the following: gcc34 -shared -fpic -o libHelloWorld.so -I/<path to JDK>/include -I/<path to JDK>/include/linux HelloWorld.c gcc34 is the name of the GCC program on my machine here at work (I don't control that) and I obviously place the real path to the JDK in that command. When I run my program, using the standard java HelloWorld, I get an error saying the following: Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/mike/Desktop/libHelloWorld.so: /home/mike/Desktop/libHelloWorld.so: wrong ELF class: ELFCLASS64 (Possible causes: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1778) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1674) at java.lang.Runtime.load0(Runtime.java:770) at java.lang.System.load(System.java:1003) at HelloWorld.<clinit>(HelloWorld.java:8) Could not find the main class: HelloWorld. Program will exit. I know I'm running a 32-bit JVM (and unfortunately, as of right now, I'm not allowed to get a 64-bit JVM). I tried telling GCC to compile in 32-bit mode using the "-m32" option, but we don't have (and again, can't get) what we need for that. Does this sound like a 32/64-bit conflict or something else?

  • How to call PopOver Controller from UITableViewCell.accessoryView?

    - by Vic
    Hi, First I would like to say that I'm really new to ipad/ipod/iphone development, and to objective-c too. With that being said, I'm trying to develop a small application targeting the iPad, using Xcode and IB, basically, I have a table, for each UITableViewCell in the table, I added to the accessoryView a button that contains an image. Here is the code: UIImage *img = [UIImage imageNamed:@"myimage.png"]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; CGRect frame = CGRectMake(0.0, 0.0, img.size.width, img.size.height); button.frame = frame; // match the button's size with the image size [button setBackgroundImage:img forState:UIControlStateNormal]; // set the button's target to this table view controller so we can interpret touch events and map that to a NSIndexSet [button addTarget:self action:@selector(checkButtonTapped:event:) forControlEvents:UIControlEventTouchUpInside]; button.backgroundColor = [UIColor clearColor]; cell.accessoryView = button; So far, so good, now the problem is that I want a PopOver control to appear when a user taps the button on the accessoryView of a cell. I tried this on the "accessoryButtonTappedForRowWithIndexPath" of the tableView: UITableViewCell *cell = [myTable cellForRowAtIndexPath:indexPath]; UIButton *button = (UIButton *)cell.accessoryView; //customViewController is the controller of the view that I want to be displayed by the PopOver controller customViewController = [[CustomViewController alloc]init]; popOverController = [[UIPopoverController alloc] initWithContentViewController: customViewController]; popOverController.popoverContentSize = CGSizeMake(147, 122); CGRect rect = button.frame; [popOverController presentPopoverFromRect:rect inView:cell.accessoryView permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES]; The problem with this code is that it shows the Popover at the top of the application View, while debugging I saw the values of "rect" and they are: x = 267 y = 13 so I think it is pretty obvious why the PopOver is being displayed so up on the view, so my question is, how can I get the correct values for the PopOver to appear just below the button on the accessoryView of the cell? Also, as you can see, I'm telling it to use the "cell.accessoryView" for the "inView:" attribute, is that okay?
