  • Understanding RTF and edit it with vb.net

    - by Jacob Kofoed
    I have this RichTextbox in my vb.net form and I would like to when a user click a button, for example to embold the selected text, how would I do this. Also, I do NOT want to use the standard vb.net expressions such as RichTextBox1.SelectedText.Font.Bold = true. I want to do something like RichTextbox1.SelectedRTF="[bold]" & RichTextBox1.SelectedRTF & "[/bold]" or whatever RTF looks like. Can I just add the RTF options random places or can a RichTextBox return an error if the text is in wrong format. I'm mostly looking for info on how to work with RTF without using the standard vb expressions. Thank you very much for any help provided

  • How to organize Python modules for PyPI to support 2.x and 3.x

    - by Craig McQueen
    I have a Python module that I would like to upload to PyPI. So far, it is working for Python 2.x. It shouldn't be too hard to write a version for 3.x now. But, after following guidelines for making modules in these places: Distributing Python Modules The Hitchhiker’s Guide to Packaging it's not clear to me how to support multiple source distributions for different versions of Python, and it's not clear if/how PyPI could support it. I envisage I would have separate code for: 2.x 2.6 (maybe, as a special case to use the new buffer API) 3.x How is it possible to set up a Python module in PyPI so that someone can do: easy_install modulename and it will install the right thing whether the user is using 2.x or 3.x?

  • Google Chrome: XMLHttpRequest.send() not working while doing POST.

    - by Dave Van den Eynde
    I'm working on an application that allows the user to send a file using a form (a POST request), and that executes a series of GET requests while that file is being uploaded to gather information about the state of the upload. It works fine in IE and Firefox, but not so much in Chrome and Safari. The problem is that even though send() is called on the XMLHttpRequest object, nothing is being requested as can be seen in Fiddler. To be more specific, an event handler is placed on the "submit" event of the form, that places a timeout function call on the window: window.setTimeout(startPolling, 10); and in this function "startPolling" sequence is started that keeps firing GET requests to receive status updates from a web service that returns text/json that can be used to update the UI. Is this a limitation (perhaps security-wise?) on WebKit based browsers? Is this a Chrome bug? (I'm seeing the same behaviour in Safari though).

  • Exclude a directory from a rewriterule using ISAPI rewrite 3

    - by mludd
    Basically I've recently added the below rule in my httpd.conf for ISAPI rewrite on an IIS server to make sure that it always defaults to lower-case file and directory names. RewriteRule ^(.*[A-Z].*)$ $1 [CL,R=301,L] This is all fine and dandy for every part of the site except for one directory which we can call /MisbehavingDir, the code in this particular directory is filled with mixed-case filenames and lots of server- and client-side scripting that would have to be rewritten to use all lower-case in order to work properly (with the RewriteRule above it seems to hit a couple of 301s in the wrong places which causes that part of the site to function poorly to say the least). Since I'm not in the mood for rewriting that part of the site I'd love to find a good way to modify the above regex so that it matches everything except paths starting with MisbehavingDir and since my regex-fu isn't really good enough I figured I'd ask here. Is there a simple "beautiful" solution to this that anyone wants to share or should I just set aside several days to rewrite the app, then test it and go through that whole dance?

  • Simplest way to create busy animation in WPF

    - by drasto
    I mentioned that there is no standard busy control in WPF. So what's the easiest way to display animated busy circle (not progress bar) such as your browser displays when loading a page ? Please if you suggest downloading control from internet make sure that this control is for free and with no licence restriction (such as I would be forced to GPL my application if I use it). Thank you in advance

  • How to compare nullable types?

    - by David_001
    I have a few places where I need to compare 2 (nullable) values, to see if they're the same. I think there should be something in the framework to support this, but can't find anything, so instead have the following: public static bool IsDifferentTo(this bool? x, bool? y) { return (x.HasValue != y.HasValue) ? true : x.HasValue && x.Value != y.Value; } Then, within code I have if (x.IsDifferentTo(y)) ... I then have similar methods for nullable ints, nullable doubles etc. Is there not an easier way to see if two nullable types are the same? Update: Turns out that the reason this method existed was because the code has been converted from VB.Net, where Nothing = Nothing returns false (compare to C# where null == null returns true). The VB.Net code should have used .Equals... instead.

  • Seriously, what's the deal with InheritInChildApplications? Does this work for anyone??

    - by mare
    I've tried wrapping my <system.web> with <location path="." InheritInChildApplications="false"> like this <location path="." InheritInChildApplications="false"> <system.web>...</system.web> </location> But VS 2010 Web Developer Express keeps saying "The 'InheritInChildApplications' attribute is not allowed" and when I run my web app there's an error: "HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid." Config Error Unrecognized attribute 'InheritInChildApplications'. I've seen some smartguys all over the Internet discussing this and how it is working for them but there's much larger number of people here at SO and other places that did not get this to work. My configuration: ASP.NET 4.0 RTM, VS 2010, IIS 7.5

  • C# Conditional Compilation and framework targets

    - by McKAMEY
    There are a few minor places where code for my project may be able to be drastically improved if the target framework were a newer version. I'd like to be able to better leverage conditional compilation in C# to switch these as needed. Something like: #if NET_40 using FooXX = Foo40; #elif NET_35 using FooXX = Foo35; #else using FooXX = Foo20; #endif Do these symbols come for free? Do I need to inject these symbols as part of the project configuration? Seems easy enough to do since I'll know which framework is being targeted from msbuild. I think I've seen that NET_40 symbol isn't defined? If so I think I could do this? #if !NET_35 && !NET_20 #define NET_40 #endif Or do I need to define it in the msbuild command: /p:DefineConstants="NET_40"

  • How to process a .proto file using protobuf-net

    - by JustSmith
    I have stated using the protobuf-net lib to communication between some of the programs I'm maintaining. I have also been able to decode messages from C# to Ruby. My ruby ProtoBuf lib is using a .proto file to generate the ruby code. In the interest of having to make changes in as few places as possible I would like to have protobuf-net use the same .proto file. Looking though the protobuf-net folders there is a Dll named ProtoBufGenerator and the protobuf exe but I cant find any instructions on if I can make protobuf-net work this way. Is this possible?

  • ASP.NET GridView second header row to span main header row

    - by Dana Robinson
    I have an ASP.NET GridView which has columns that look like this: | Foo | Bar | Total1 | Total2 | Total3 | Is it possible to create a header on two rows that looks like this? | | Totals | | Foo | Bar | 1 | 2 | 3 | The data in each row will remain unchanged as this is just to pretty up the header and decrease the horizontal space that the grid takes up. The entire GridView is sortable in case that matters. I don't intend for the added "Totals" spanning column to have any sort functionality. Edit: Based on one of the articles given below, I created a class which inherits from GridView and adds the second header row in. namespace CustomControls { public class TwoHeadedGridView : GridView { protected Table InnerTable { get { if (this.HasControls()) { return (Table)this.Controls[0]; } return null; } } protected override void OnDataBound(EventArgs e) { base.OnDataBound(e); this.CreateSecondHeader(); } private void CreateSecondHeader() { GridViewRow row = new GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal); TableCell left = new TableHeaderCell(); left.ColumnSpan = 3; row.Cells.Add(left); TableCell totals = new TableHeaderCell(); totals.ColumnSpan = this.Columns.Count - 3; totals.Text = "Totals"; row.Cells.Add(totals); this.InnerTable.Rows.AddAt(0, row); } } } In case you are new to ASP.NET like I am, I should also point out that you need to: 1) Register your class by adding a line like this to your web form: <%@ Register TagPrefix="foo" NameSpace="CustomControls" Assembly="__code"%> 2) Change asp:GridView in your previous markup to foo:TwoHeadedGridView. Don't forget the closing tag. Another edit: You can also do this without creating a custom class. Simply add an event handler for the DataBound event of your grid like this: protected void gvOrganisms_DataBound(object sender, EventArgs e) { GridView grid = sender as GridView; if (grid != null) { GridViewRow row = new GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal); TableCell left = new TableHeaderCell(); left.ColumnSpan = 3; row.Cells.Add(left); TableCell totals = new TableHeaderCell(); totals.ColumnSpan = grid.Columns.Count - 3; totals.Text = "Totals"; row.Cells.Add(totals); Table t = grid.Controls[0] as Table; if (t != null) { t.Rows.AddAt(0, row); } } } The advantage of the custom control is that you can see the extra header row on the design view of your web form. The event handler method is a bit simpler, though.

  • What's the best way to handle the same shortcut in WPF and WinForms controls?

    - by Anthony Brien
    I have a WPF application with the following KeyBinding on its main window: <KeyBinding Command="Commands:EditCommands.Undo" Gesture="CTRL+Z" /> <KeyBinding Command="Commands:EditCommands.Redo" Gesture="CTRL+Y" /> This makes the command respond to the shortcut fine. However, in all the places where I have embedded WinForms text boxes or rich text boxes, I've lost the ability to use those shortcuts. If I remove the above bindings, the WinForms shortcuts work fine. How can I support these shortcuts in both WinForms and WPF? I'd prefer a generic method since this problem is likely to affect many other commands with the same keybindings.

  • What is a robust method for capturing screen of child window in Windows 7?

    - by Dogan Demir
    Pardon my frustration. I've asked about this in many places and I seriously don't think that there wouldn't be a way in Windows 7 SDK to accomplish this. All I want, is to capture part of a 'child window' ( setParent() ) created by a parent. I used to do this with bitblt() but the catch is that the child window can be any type of application, and in my case has OpenGL running in a section of it. If I bitblt() that, then the OGL part comes blank, doesn't get written to the BMP. DWM, particularly dwmRegisterThumbnail() doesn't allow thumbnail generation of child windows. So please give me a direction. Thanks.

  • Nested property binding

    - by EtherealMonkey
    Recently, I have been trying to wrap my mind around the BindingList<T> and INotifyPropertChanged. More specifically - How do I make a collection of objects (having objects as properties) which will allow me to subscribe to events throughout the tree? To that end, I have examined the code offered as examples by others. One such project that I downloaded was Nested Property Binding - CodeProject by "seesharper". Now, the article explains the implementation, but there was a question by "Someone@AnotherWorld" about "INotifyPropertyChanged in nested objects". His question was: Hi, nice stuff! But after a couple of time using your solution I realize the ObjectBindingSource ignores the PropertyChanged event of nested objects. E.g. I've got a class 'Foo' with two properties named 'Name' and 'Bar'. 'Name' is a string an 'Bar' reference an instance of class 'Bar', which has a 'Name' property of type string too and both classes implements INotifyPropertyChanged. With your binding source reading and writing with both properties ('Name' and 'Bar_Name') works fine but the PropertyChanged event works only for the 'Name' property, because the binding source listen only for events of 'Foo'. One workaround is to retrigger the PropertyChanged event in the appropriate class (here 'Foo'). What's very unclean! The other approach would be to extend ObjectBindingSource so that all owner of nested property which implements INotifyPropertyChanged get used for receive changes, but how? Thanks! I had asked about BindingList<T> yesterday and received a good answer from Aaronaught. In my question, I had a similar point as "Someone@AnotherWorld": if Keywords were to implement INotifyPropertyChanged, would changes be accessible to the BindingList through the ScannedImage object? To which Aaronaught's response was: No, they will not. BindingList only looks at the specific object in the list, it has no ability to scan all dependencies and monitor everything in the graph (nor would that always be a good idea, if it were possible). I understand Aaronaught's comment regarding this behavior not necessarily being a good idea. Additionally, his suggestion to have my bound object "relay" events on behalf of it's member objects works fine and is perfectly acceptable. For me, "re-triggering" the PropertyChanged event does not seem so unclean as "Someone@AnotherWorld" laments. I do understand why he protests - in the interest of loosely coupled objects. However, I believe that coupling between objects that are part of a composition is logical and not so undesirable as this may be in other scenarios. (I am a newb, so I could be waaayyy off base.) Anyway, in the interest of exploring an answer to the question by "Someone@AnotherWorld", I altered the MainForm.cs file of the example project from Nested Property Binding - CodeProject by "seesharper" to the following: using System; using System.Collections.Generic; using System.ComponentModel; using System.Core.ComponentModel; using System.Windows.Forms; namespace ObjectBindingSourceDemo { public partial class MainForm : Form { private readonly List<Customer> _customers = new List<Customer>(); private readonly List<Product> _products = new List<Product>(); private List<Order> orders; public MainForm() { InitializeComponent(); dataGridView1.AutoGenerateColumns = false; dataGridView2.AutoGenerateColumns = false; CreateData(); } private void CreateData() { _customers.Add( new Customer(1, "Jane Wilson", new Address("98104", "6657 Sand Pointe Lane", "Seattle", "USA"))); _customers.Add( new Customer(1, "Bill Smith", new Address("94109", "5725 Glaze Drive", "San Francisco", "USA"))); _customers.Add( new Customer(1, "Samantha Brown", null)); _products.Add(new Product(1, "Keyboard", 49.99)); _products.Add(new Product(2, "Mouse", 10.99)); _products.Add(new Product(3, "PC", 599.99)); _products.Add(new Product(4, "Monitor", 299.99)); _products.Add(new Product(5, "LapTop", 799.99)); _products.Add(new Product(6, "Harddisc", 89.99)); customerBindingSource.DataSource = _customers; productBindingSource.DataSource = _products; orders = new List<Order>(); orders.Add(new Order(1, DateTime.Now, _customers[0])); orders.Add(new Order(2, DateTime.Now, _customers[1])); orders.Add(new Order(3, DateTime.Now, _customers[2])); #region Added by me OrderLine orderLine1 = new OrderLine(_products[0], 1); OrderLine orderLine2 = new OrderLine(_products[1], 3); orderLine1.PropertyChanged += new PropertyChangedEventHandler(OrderLineChanged); orderLine2.PropertyChanged += new PropertyChangedEventHandler(OrderLineChanged); orders[0].OrderLines.Add(orderLine1); orders[0].OrderLines.Add(orderLine2); #endregion // Removed by me in lieu of region above. //orders[0].OrderLines.Add(new OrderLine(_products[0], 1)); //orders[0].OrderLines.Add(new OrderLine(_products[1], 3)); ordersBindingSource.DataSource = orders; } #region Added by me // Have to wait until the form is Shown to wire up the events // for orderDetailsBindingSource. Otherwise, they are triggered // during MainForm().InitializeComponent(). private void MainForm_Shown(object sender, EventArgs e) { orderDetailsBindingSource.AddingNew += new AddingNewEventHandler(orderDetailsBindSrc_AddingNew); orderDetailsBindingSource.CurrentItemChanged += new EventHandler(orderDetailsBindSrc_CurrentItemChanged); orderDetailsBindingSource.ListChanged += new ListChangedEventHandler(orderDetailsBindSrc_ListChanged); } private void orderDetailsBindSrc_AddingNew( object sender, AddingNewEventArgs e) { } private void orderDetailsBindSrc_CurrentItemChanged( object sender, EventArgs e) { } private void orderDetailsBindSrc_ListChanged( object sender, ListChangedEventArgs e) { ObjectBindingSource bindingSource = (ObjectBindingSource)sender; if (!(bindingSource.Current == null)) { // Unsure if GetType().ToString() is required b/c ToString() // *seems* // to return the same value. if (bindingSource.Current.GetType().ToString() == "ObjectBindingSourceDemo.OrderLine") { if (e.ListChangedType == ListChangedType.ItemAdded) { // I wish that I knew of a way to determine // if the 'PropertyChanged' delegate assignment is null. // I don't like the current test, but it seems to work. if (orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].Product == null) { orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].PropertyChanged += new PropertyChangedEventHandler( OrderLineChanged); } } if (e.ListChangedType == ListChangedType.ItemDeleted) { // Will throw exception when leaving // an OrderLine row with unitialized properties. // // I presume this is because the item // has already been 'disposed' of at this point. // *but* // Will it be actually be released from memory // if the delegate assignment for PropertyChanged // was never removed??? if (orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].Product != null) { orders[ ordersBindingSource.Position].OrderLines[ e.NewIndex].PropertyChanged -= new PropertyChangedEventHandler( OrderLineChanged); } } } } } private void OrderLineChanged(object sender, PropertyChangedEventArgs e) { MessageBox.Show(e.PropertyName, "Property Changed:"); } #endregion } } In the method private void orderDetailsBindSrc_ListChanged(object sender, ListChangedEventArgs e) I am able to hook up the PropertyChangedEventHandler to the OrderLine object as it is being created. However, I cannot seem to find a way to unhook the PropertyChangedEventHandler from the OrderLine object before it is being removed from the orders[i].OrderLines list. So, my questions are: Am I simply trying to do something that is very, very wrong here? Will the OrderLines object that I add the delegate assignments to ever be released from memory if the assignment is not removed? Is there a "sane" method of achieving this scenario? Also, note that this question is not specifically related to my prior. I have actually solved the issue which had prompted me to inquire before. However, I have reached a point with this particular topic of discovery where my curiosity has exceeded my patience - hopefully someone here can shed some light on this?

  • [Android] Is there a way to make ellipsize="marquee" always scroll?

    - by Matthias
    I want to use the marquee effect on a TextView, but the text is only being scrolled when the TextView gets focus. That's a problem, because in my case, it can't. I am using: android:ellipsize="marquee" android:marqueeRepeatLimit="marquee_forever" Is there a way to have the TextView always scroll its text? I've seen this being done in the Android Market app, where the app name will scroll in the title bar, even if it doesn't receive focus, but I couldn't find this being mentioned in the API docs.

  • How can you add a UIGestureRecognizer to a UIBarButtonItem as in the common undo/redo UIPopoverContr

    - by SG
    Problem In my iPad app, I cannot attach a popover to a button bar item only after press-and-hold events. But this seems to be standard for undo/redo. How do other apps do this? Background I have an undo button (UIBarButtonSystemItemUndo) in the toolbar of my UIKit (iPad) app. When I press the undo button, it fires it's action which is undo:, and that executes correctly. However, the "standard UE convention" for undo/redo on iPad is that pressing undo executes an undo but pressing and holding the button reveals a popover controller where the user selected either "undo" or "redo" until the controller is dismissed. The normal way to attach a popover controller is with presentPopoverFromBarButtonItem:, and I can configure this easily enough. To get this to show only after press-and-hold we have to set a view to respond to "long press" gesture events as in this snippet: UILongPressGestureRecognizer *longPressOnUndoGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPressOnUndoGesture:)]; //Broken because there is no customView in a UIBarButtonSystemItemUndo item [self.undoButtonItem.customView addGestureRecognizer:longPressOnUndoGesture]; [longPressOnUndoGesture release]; With this, after a press-and-hold on the view the method handleLongPressOnUndoGesture: will get called, and within this method I will configure and display the popover for undo/redo. So far, so good. The problem with this is that there is no view to attach to. self.undoButtonItem is a UIButtonBarItem, not a view. Possible solutions 1) [The ideal] Attach the gesture recognizer to the button bar item. It is possible to attach a gesture recognizer to a view, but UIButtonBarItem is not a view. It does have a property for .customView, but that property is nil when the buttonbaritem is a standard system type (in this case it is). 2) Use another view. I could use the UIToolbar but that would require some weird hit-testing and be an all around hack, if even possible in the first place. There is no other alternative view to use that I can think of. 3) Use the customView property. Standard types like UIBarButtonSystemItemUndo have no customView (it is nil). Setting the customView will erase the standard contents which it needs to have. This would amount to re-implementing all the look and function of UIBarButtonSystemItemUndo, again if even possible to do. Question How can I attach a gesture recognizer to this "button"? More specifically, how can I implement the standard press-and-hold-to-show-redo-popover in an iPad app? Ideas? Thank you very much, especially if someone actually has this working in their app (I'm thinking of you, omni) and wants to share...

  • How do I add a toolbar to a region with ExtJS

    - by gargantaun
    I have a border layout in ExtJS, The north region contains some HTML, but also needs to contain a toolbar like this... So i've managed to get the border layout set up, added the html to the North Region of the layout, but I can't find any workable examples of how to implement a tool bar. I have found lot's of examples of toolbars on their own, but I've not got the luxury or learning ExtJs thoroughly so it's all greek to me. I suspect there's a way to define a tool bar outside of the cumbersome JSON style flow of creating a layout and somehow attaching it to the region, and I'm hoping it's relativley simple to do. If someone can explain how I'd do this, it would really help. Here's the code so far... //make sure YOUR path is correct to this image!! Ext.BLANK_IMAGE_URL = '../../ext-2.0.2/resources/images/default/s.gif'; //this runs on DOM load - you can access all the good stuff now. Ext.onReady(function(){ var viewport = new Ext.Viewport({ layout: "border", border: false, renderTo: Ext.getBody(), items: [ // ------------------------------------------------------------------ { region: "north", id : "toolbar-area", xtype: 'panel', html: [ "<div id=\"html-header\">", "<div id=\"council-logo\"></div>", "<ul id=\"ancillary-menu\">", "<li><a href=\"#\">Logout</a></li>", "<li><a href=\"#\">Gazeteer Home</a></li>", "<li>Hello Rachel</li>", "</ul>", "<img id=\"inteligent-logo\" src=\"applied-images/logos/inteligent.gif\">", "</div>" ], /* ++++++++++++++++++++++++++++++++++++++++++++ */ /* The toolbar needs to go around here.... */ /* ++++++++++++++++++++++++++++++++++++++++++++ */ height: 100 }, // ------------------------------------------------------------------ // WEST // ------------------------------------------------------------------ { region: 'west', xtype: 'panel', split: true, resizeable: false, maxWidth : 350, minWidth : 349, collapsible: true, title: 'Gazetteer Explorer', width: 350, minSize: 150, // -------------------------------------------------------------- title: 'Nested Layout', layout: 'border', border: false, id: "west", items: [ { // *********************************************** // Search Form // *********************************************** region : "north", height: 300, split : true, id : "left-form-panel", items : [{ xtype : "form", id : "search-form", items : [ // Authority combo box // =============================== { xtype : "combo", fieldLabel : "Authority", name : "authority", hiddenName : "authority", id : "authority-combo" }, // =============================== // Search Fieldset // =============================== { xtype : "fieldset", autoHeight : true, title : "Search by...", id : "search-fieldset", items : [ // Ref Number text Box // %%%%%%%%%%%%%%%% { xtype : "textfield", name : "ref-number", fieldLabel : "Ref.

  • CSRF (Cross-site request forgery) attack example and prevention in PHP

    - by Saif Bechan
    I have an website where people can place a vote like this: http://mysite.com/vote/25 This will place a vote on item 25. I want to only make this available for registered users, and only if they want to do this. Now I know when someone is busy on the website, and someone gives them a link like this: http://mysite.com/vote/30 then the vote will be places for him on the item without him wanting to do this. I have read the explanation on the OWASP website, but i don't really understand it Is this an example of CSFR, and how can I prevent this. The best thing i can think off is adding something to the link like a hash. But this will be quite irritating to put something on the end of all the links. Is there no other way of doing this. Another thing can someone maybe give me some other example of this, because the website seems fairly fugue to me.

  • Why am i getting "error:1409F07F:SSL routines:SSL3_WRITE_PENDING: bad write retry" error while attem

    - by Amit Ben Shahar
    I came across this error, and had to look in a lot of placed until i was able to find the reason for this error and thought this might save someone else the hassle. the reason is pretty simple: when SSL_Write returns with SSL_ERROR_WANT_WRITE or SSL_ERROR_WANT_READ, you have to repeat the call to SSL_write with the same parameters again, after the condition is satisfied. Calling it with different parameters, will yield the 1409F07F bar write retry error. Hope this saved someone's important time :P Amit.

  • When is Visual Studio 2010 expected to RTM?

    - by Chris Pietschmann
    Microsoft originally slated the final release build for April 12, 2010. Somasegar said the Visual Studio 2010 and .NET Framework 4 releases will now be pushed back "a few weeks." I know the version / product name says "2010", but that doesn't necessarily mean that it will RTM in 2010. After all VS'2008 RTM'd in November 2007. The last Beta of VS'2008 came out in July 2007, and it RTM'd in November. So based on the previous version that places VS'2010 to RTM in September 2010 at the very earliest since the first Beta just came out in May. Anyone have any other speculations?

    Hi, I'm trying to convert this c code(http://nashruddin.com/OpenCV_Eye_Detection) to the python code, but in c style, he used cvROI thing, since ROI functions are not supported by python-opencv, I tried cvGetSubRect so Here is the eye detection part of the code : eye_region = cvGetSubRect(image,cvRect(face.x,int(face.y + (face.height/4)),face.width,int(face.height/2))) eyes = cvHaarDetectObjects(eye_region,eyeCascade,memo,1.15,3,0,cvSize(25,15)) for e in eyes: cvRectangle(image, cvPoint( int(e.x), int(e.y)), cvPoint(int(e.x + e.width), int(e.y + e.height)), CV_RGB(0, 255, 0), 1, 8, 0) return image; When I run this code, It draws rectangles irrelevant places. I thought, eye_region coordinates are wrong, and tried some coordinates, but it didn't work. Any idea ? Note :Face detection method works very well, and it's code is same with the eye detection method.
