  • Problems debugging using Cygwin gdb in Eclipse CDT(Helios)

    - by Rohan
    I am trying to debug an application using Eclipse CDT and cygwin gdb and I am facing a problem if my code calls Sleep(), it looks like whenever a sleep is encountered in the code the debugger seems to go in an infinite loop(I meant it never terminates or hit a breakpoint after sleep). On pressing pause the code is stuck on one of the thread on sigint::interrupt. Even my debugger console windows throw these error in the console output: [New thread 5968.0x1f98] Error: dll starting at 0x774a0000 not found. Error: dll starting at 0x775c0000 not found. [New thread 5968.0x19e8] Any idea what are these errors about? It would be helpful if someone can help me out here as I am new to eclipse and I am used to using VS so it has made be lazy to be honest and expect things to work out of box. Here are more details if required Windows 7 x64 bit. Eclipse 3.6 Helios with CDT plug-in compiled from the CVS head. Cygwin latest from website, I think it is 1.71

  • managing images in an iphone/ipad universal app

    - by taber
    Hi, I'm just curious as to what methods people are using to dynamically use larger or smaller images in their universal iPhone/iPad apps. I created a large test image and I tried scaling down (using cocos2d) by 0.46875. After viewing that in the iPhone 4.0 simulator I found the results were pretty crappy... rough pixel edges, etc. Plus, loading huge image files for iPhone users when they don't need them is pretty lame. So I guess what I will probably have to do is save out two versions of every sprite... large (for the iPad side) and small (for iPhone/iPod Touch) then detect the user's device and spit out the proper sprite like so: NSString *deviceType = [UIDevice currentDevice].model; CCSprite *test; if([deviceType isEqualToString:@"iPad"]) { test = [CCSprite spriteWithFile:@"testBigHuge.png"]; } else { test = [CCSprite spriteWithFile:@"testRegularMcTiny.png"]; } [self addChild: test]; How are you guys doing this? I'd rather avoid sprinkling all of my code with if statements like this. I want to also avoid using .xib files since it's an OpenGL-based app. Thanks!

  • Uploading a zip file to a jsp and extract the content in another jsp

    - by sunnyj
    I want to upload a zip file in a jsp page and the user is sent to another jsp page after he selects and uploads the file. In this second page I want to 1.)extract the uploaded zip file. 2.)read some content from the extracted file(s) and allow the user to change/edit them 3.)save the user changes in the files. 4.)zip the files again and save it in another destination. Please suggest me a rough outline of a solution as I am stuck in the phase in which I get the uploaded file and re-direct the user to the second jsp.

  • How to improve WinForms MSChart performance?

    - by Marcel
    Hi all, I have created some simple charts (of type FastLine) with MSChart and update them with live data, like below: . To do so, I bind an observable collection of a custom type to the chart like so: // set chart data source this._Chart.DataSource = value; //is of type ObservableCollection<SpectrumLevels> //define x and y value members for each series this._Chart.Series[0].XValueMember = "Index"; this._Chart.Series[1].XValueMember = "Index"; this._Chart.Series[0].YValueMembers = "Channel0Level"; this._Chart.Series[1].YValueMembers = "Channel1Level"; // bind data to chart this._Chart.DataBind(); //lasts 1.5 seconds for 8000 points per series At each refresh, the dataset completely changes, it is not a scrolling update! With a profiler I have found that the DataBind() call takes about 1.5 seconds. The other calls are negligible. How can I make this faster? Should I use another type than ObservableCollection? An array probably? Should I use another form of data binding? Is there some tweak for the MSChart that I may have missed? Should I use a sparsed set of date, having one value per pixel only? Have I simply reached the performance limit of MSCharts? From the type of the application to keep it "fluent", we should have multiple refreshes per second. Thanks for any hints!

  • Telerik ASP.NET AJAX - Ajax Update Label with dynamic created Docks

    - by csharpnoob
    Hi, i try to Update a simple Label on Close Event of dynamic created RadDock. Works fine so far, Label gets the correct values but doesnt updates it. RadDock dock = new RadDock(); dock.DockMode = DockMode.Docked; dock.UniqueName = Guid.NewGuid().ToString(); dock.ID = string.Format("RadDock{0}", dock.UniqueName); dock.Title = slide.slideName; dock.Text = string.Format("Added at {0}", DateTime.Now); dock.Width = Unit.Pixel(300); dock.AutoPostBack = true; dock.CommandsAutoPostBack = true; dock.Command += new DockCommandEventHandler(dock_Command); ... void dock_Command(object sender, DockCommandEventArgs e) { Status.Text = "Removed " + ((RadDock)sender).Title + " " + ((RadDock)sender).Text; } I tried to do this: RadAjaxManager1.AjaxSettings.AddAjaxSetting(dock, Status, null); while creating the docks, but on runtime i get a NullReference Excepetion. On a Button registered with the RadAjaxManager it works to show the value assigned by dock_command. protected void Button1_Click(object sender, EventArgs e) { Status.Text = Status.Text; } UPDATE: The RadAjaxManager was created with integrated Wizzard of VS2008. Can't select the Docks, because the are generated while runtime. On Backend its included in AutoCompletion, so the NullReference has nothing to do with the AjaxManager itself. Like i said, works fine with the Button. <telerik:RadAjaxManager ID="RadAjaxManager1"> <telerik:AjaxSetting AjaxControlID="Button1"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="Label1"></telerik:AjaxUpdatedControl> </UpdatedControls> </telerik:AjaxSetting>

  • jQuery / Dynatree: How to use Json or ul/li together with IFrame sample

    - by ggerri
    Hi I'm a newbie with dynatree, but happy that i've found this supercool plugin. On the dynatree site, I've found an example how to use it with IFrames http://wwwendt.de/tech/dynatree/doc/sample-iframe.html I was able to adapt the IFrame example successfully. But i'm a bit stuck here, because I'd like to load the tree either via UL/LI or better, with Jason/Ajax. my problem now is, that I dont understand how to provide ther url/links with LI or Jason, so that clicking an entry still opens the linked site in the iframe. Also don't know how I have to format parents/children/subchildren in Json.. Would anybody be so kind to give a sample with iframe and jason/ajax or iframe with ul/li? Thanks a lot :-) G

  • How To debug Android app on Emulator using NetBeans IDE

    - by tobrien
    I recently downloaded the latest NetBeans IDE (for MACOSX) and imported/migrated a project over from the ECLIPSE environment. Everything looks, and works well... except that EMULATOR gets stuck "waiting for the debugger to attach." I tried "Attaching Debugger..." and set the PORT value to every case I've ever read about (8200, 8700, 5555, etc.) but the connection is refused. I am of the opinion that this is not the preferred way to start a debugging session in NetBeans for Android. What am I missing?

  • XNA vs SlimDX for offscreen renderer

    - by Groky
    Hello, I realise there are numerous questions on here asking about choosing between XNA and SlimDX, but these all relate to game programming. A little background: I have an application that renders scenes from XML descriptions. Currently I am using WPF 3D and this mostly works, except that WPF has no way to render scenes offscreen (i.e. on a server, without displaying them in a window), and also rendering to a bitmap causes WPF to fallback to software rendering. So I'm faced with having to write my own renderer. Here are the requirements: Mix of 3D and 2D elements. Relatively few elements per scene (tens of meshes, tens of 2D elements). Large scenes (up to 3000px square for print). Only a single frame will be rendered (i.e. FPS is not an issue). Opacity masks. Pixel shaders. Software fallback (servers may or may not have a decent gfx card). Possibility of being rendered offscreen. As you can see it's pretty simple stuff and WPF can manage it quite nicely except for the not-being-able-to-export-the-scene problem. In particular I don't need many of the things usually needed in game development. So bearing that in mind, would you choose XNA or SlimDX? The non-rendering portion of the code is already written in C#, so want to stick with that.

  • Does GoDaddy supports RESTful services via WCF

    - by Amir Naor
    After deploying a WCF RESTful service that i created using the REST started kit, i got several errors that i managed to solve following this post: http://www.edoverip.com/edoverip/index.php/2009/01/30/running-wcf-on-godaddy Now i'm stuck with this error: IIS specified authentication schemes 'Basic, Anonymous', but the binding only supports specification of exactly one authentication scheme. Valid authentication schemes are Digest, Negotiate, NTLM, Basic, or Anonymous. Change the IIS settings so that only a single authentication scheme is used I saw that others got to this point without a solution. GoDaddy support dont know nothing. Is it possible at all? Are there any web hosting services that you know that support that?

  • customizing webmail cpanel login area with php

    - by Coolate
    I have webmail setup similar to what hostgator has (I host with them and looks like they use their own system). I'm trying to customize the login page of webmail, but am a little stuck. When you go to webmail page/port below, you get a popup login form, not a web login form. If you hit cancel, it finally loads the web login form. http://www.hostgator.com/webmail/ Note that I'm using hostgator's webmail link just as an example because they use the same script. Is there a way through php (or any other way) to prevent the popup login form and go straight to the web login form? The next step would be to theme it, etc. etc. Any ideas or tutorials on how this script works?

  • tcpdump on dd-wrt router

    - by Senica Gonzalez
    I'm trying to capture packets from two devices on my network. I have tcpdump installed on my dd-wrt router and working correctly. However, the only packets I capture are broadcast packets when using a tcpdump statement that states only those two devices ./tcpdump -w /tmp/capture.pcap dst 192.168.3.105 or src 192.168.3.105 or dst 192.168.3.136 or src 192.168.3.136 I'm capturing on intefface br0. Is that correct? Both devices are plugged in directly to the ports 1 and 2 with ip addresses 192.168.3.105 and 192.168.3.136 respectively. Do I need to set br0 in promiscuous mode? A little stuck. Thanks.

  • Unable to Create New Incidents in Dynamics CRM with Java and Axis2

    - by Lutz
    So I've been working on trying to figure this out, oddly when I ran it one machine I got a generic Axis Fault with no description, but now on another machine I'm getting a different error message, but I'm still stuck. Basically I'm just trying to do what I thought would be a fairly trivial task of creating a new incident in Microsoft Dynamics CRM 4.0 via a web services call. I started by downloading the XML from http://hostname/MSCrmServices/2007/CrmService.asmx and generating code from it using Axis2.

  • jQuery to add vertical scroll bar for a fixed height div container

    - by Michael Mao
    Hi all: This is uni homework so sorry about :my password protected url Please enter usersame as "uts" and password as "10479475", without the wrapper quotes. It it almost completed, please follow simple steps to see where my problem dwells: step1: click on any continent highlighted on world map; step2: click on any city marked on continent map; step3: enter quantity ranging from 1 to 6 into the upper-right table; step4 : there you go, in the table below, once row is equal or greater than 3, then the size of table starts to "overlap" on top of the footer section and continues to grow, which is not what I want. I want to achieve the effect that the table size has a limited max-height, so once actual height exceeds the threshold, then I can have a vertical scroll bar so to "stack up" my table and not to break the overall structure. It turns out that my lazy initial design now gets myself stuck in a problem... Any suggestion and hint on how to get this?

  • WPF DataGrid window resize does not resize DataGridColumns

    - by skylap
    I have a WPF DataGrid (from the WPFToolkit package) like the following in my application. <Controls:DataGrid> <Controls:DataGrid.Columns> <Controls:DataGridTextColumn Width="1*" Binding="{Binding Path=Column1}" Header="Column 1" /> <Controls:DataGridTextColumn Width="1*" Binding="{Binding Path=Column2}" Header="Column 2" /> <Controls:DataGridTextColumn Width="1*" Binding="{Binding Path=Column3}" Header="Column 3" /> </Controls:DataGrid.Columns> </Controls:DataGrid> The column width should be automatically adjusted such that all three columns fill the width of the grid, so I set Width="1*" on every column. I encountered two problems with this approach. When the ItemsSource of the DataGrid is null or an empty List, the columns won't size to fit the width of the grid but have a fixed width of about 20 pixel. Please see the following picture: http://img169.imageshack.us/img169/3139/initialcolumnwidth.png When I maximize the application window, the columns won't adapt their size but keep their initial size. See the following picture: http://img88.imageshack.us/img88/9362/columnwidthaftermaximiz.png When I resize the application window with the mouse, the columns won't resize. I was able to solve problem #3 by deriving a sub class from DataGrid and override the DataGrid's OnRenderSizeChanged method as follows. protected override void OnRenderSizeChanged(SizeChangedInfo sizeInfo) { base.OnRenderSizeChanged(sizeInfo); foreach (var column in Columns) { var tmp = column.GetValue(DataGridColumn.WidthProperty); column.ClearValue(DataGridColumn.WidthProperty); column.SetValue(DataGridColumn.WidthProperty, tmp); } } Unfortunately this does not solve problems #1 and #2. How can I get rid of them?

  • Cognos 8.3 - date prompt macro problem

    - by Jacob
    In Report Studio 8.3, I've got this raw SQL query running against a MySQL 5.1 data source: SELECT enc.encounterID, enc.date FROM enc WHERE enc.date between #prompt('textPromptStartDate')# AND #prompt('textPromptEndDate', 'date')# This produces text prompts for the user. If the user enters dates into these prompts in the format of 'YYYY-MM-DD', e.g. '2010-01-15', the query works fine. But I want to replace the text prompts with proper Date prompts. When I try replacing the above prompts with #prompt('datePromptStartDate', 'date') AND #prompt('datePromptEndDate', 'date')# the query runs (no errors are generated), but I get an empty result set. I have a feeling I need to adjust the date format that the date prompt macro returns, but I'm stuck after many hours of experimentation as to how to debug this.

  • CSS: Setting width/height as Percentage minus pixels

    - by Mega Matt
    Hi all, I've seen this question asked in a couple other contexts on SO, but I thought it would be worth asking again for my particular case. I'm trying to create some re-usable CSS classes for more consistency and less clutter on my site, and I'm stuck on trying to standardize one thing I use frequently. I have a container div that I don't want to set the height for (because it will vary depending on where on the site it is), and inside it is a header div, and then an unordered list of items, all with CSS applied to them. It looks a lot like this: I want the unordered list to take up the remaining room in the container div, knowing that the header div is 18px tall. I just don't know how to specify the list's height as "the result of 100% minus 18px". Does anyone have any advice in this situation? Thanks very much.

  • GCC vs Microsoft : Undefined reference to `_chkstk'?

    - by SethCoder
    I am using CodeBlocks and MinGW toolchain which is essentially GCC. I was using VStudio but I want to get away from it to do cross platform development. There seems to be some microsoft specific references in some libraries that I am linking, specifically in CXImage SDK (_chkstk). I presume the library was put together using VS. From my searches I have learned that GCC uses _alloca rather than _chkstk. I still want to use CXImage for some stuff I am doing. My question: Is there a way around this problem or am I stuck with ditching libs such as this if I want to use GCC?

I do not want any compressing... is there a way to solve this? thanks.

  • OCR with Neural network: data extraction

    - by Sebastian Hoitz
    I'm using the AForge library framework and its neural network. At the moment when I train my network I create lots of images (one image per letter per font) at a big size (30 pt), cut out the actual letter, scale this down to a smaller size (10x10 px) and then save it to my harddisk. I can then go and read all those images, creating my double[] arrays with data. At the moment I do this on a pixel basis. So once I have successfully trained my network I test the network and let it run on a sample image with the alphabet at different sizes (uppercase and lowercase). But the result is not really promising. I trained the network so that RunEpoch had an error of about 1.5 (so almost no error), but there are still some letters left that do not get identified correctly in my test image. Now my question is: Is this caused because I have a faulty learning method (pixelbased vs. the suggested use of receptors in this article: http://www.codeproject.com/KB/cs/neural_network_ocr.aspx - are there other methods I can use to extract the data for the network?) or can this happen because my segmentation-algorithm to extract the letters from the image to look at is bad? Does anyone have ideas on how to improve it?

  • How can a separator be added between items in an ItemsControl

    - by Grandpappy
    I'm needing to display a list of numbers from a collection in an Items Control. So the items are: "1", "2", "3". When they are rendered, I need them separated by a comma (or something similar). So the above 3 items would look like this: "1, 2, 3". How can I add a separator to the individual items, without having one tacked on the end of the list? I am not stuck on using an ItemsControl, but that's what I had started to use.

  • android maps: How to Long Click a Map?

    - by vamsibm
    Hi. How do I long click on a mapview so that a place marker appears at that point on the map? I tried a couple ways without success: 1) Using setOnLongClickListener on the MapvView which never detected the longclicks. 2) My other idea was to extend MapView to override dispatchTouchEvent .. Create a GestureDetector to respond to longpress callback. But I was stuck midway here as I could not get a handle to my subclassed Mapview. i.e. MyMapview mymapview; //MyMapView extends MapView mymapView = (MyMapView) findViewById(R.id.map); //results in a classcast exception 3) The only other way I know how to try this is: Detect a MotionEvent.ACTION_DOWN and post a delayed runnable to a handler and detect longpress if the two other events: acton_move or an action_up, have not happened. Can someone provide thoughts on any of these methods to detect long presses? Thanks in advance. Bd

  • YUV Textures and Shaders

    - by Luca
    I've always used RGB textures. Now comes up the need of use of YUV textures (a set of three texture, specifying 1 luminance and 2 chrominance channels). Of course the YUV texture could be converted on CPU, getting the RGB texture usable as usual... but I need to get RGB pixel directly on GPU, to avoid unnecessary processor load... The problem became strange, since I require to specifyin the shader source, because a single texture, the following items: Three samplers uniforms, one for each channel Two integer uniforms, for specifying the chrominance channels sampling a mat3 uniform, for specific YUV to RGB conversion matrix. This should be done for each YUV texture... Is it possible to "compress" required uniforms, and getting RGB values quite easily? Actually i think this could aid: Texture sizes, including mipmaps, could be queried. With this, its possible to save the two integer uniforms, since the uniform values are derived the ratio between texture extents The mat3 uniforms could be collected as globals, and with preprocessor could be selected. But what design should I use for specify three (related) textures? Is it possible to use textures levels for accessing multiple textures? Texture arrays could be usable? And what about using rectangle textures, which doesn't supports mipmaps? Maybe a shader abstraction (struct definition and related function) could aid? Thank you.
