• Windows API calls from assembly while minimizing program size

  - by takteek

  I'm trying to write a program in assembly and make the resulting executable as small as possible. Some of what I'm doing requires windows API calls to functions such as WriteProcessMemory. I've had some success with calling these functions, but after compiling and linking, my program comes out in the range of 14-15 KB. (From a source of less than 1 KB) I was hoping for much, much less than that. I'm very new to doing low level things like this so I don't really know what would need to be done to make the program smaller. I understand that the exe format itself takes up quite a bit of space. Can anything be done to minimize that? I should mention that I'm using NASM and GCC but I can easily change if that would help.

• How can I launch a missile?

  - by doug.stanhope

  I am working on an open-source missile launcher application. I have added a big red button to a Form that says "Launch Missile". When I click the button, the event handler gets called. From the event handler I call a method named LaunchMissile(). So far so good, but how do you launch a missile from C# code? Will I have to write this code myself or is there an API or third party library for launching missiles? Please add sample code for various launch scenarios: orbit, moon, mars, etc.

• How can I avoid the overflow when wheel scolling WPF DataGrid

  - by Jan Bannister

  When I use the mouse wheel to scroll the WPF Toolkit DataGrid on a Vista 64 Machine I get a cryptic low level error: at System.IntPtr.op_Explicit(IntPtr value) at System.Windows.Interop.HwndMouseInputProvider.FilterMessage(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at System.Windows.Interop.HwndSource.InputFilterMessage(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) I logged an issue on CodePlex. But has anyone found a way to resolve this already?

• Objective-C Framework PSMTabBarControl does not work - NSTabView Tabs with Style

  - by ahmet2106

  Hello everybody In my App I'm trying to get PSMTabBarControl working, but all I do - nothing... I have copied the framework File in my Frameworks folder of my App, then included it. In my InterfaceBuilder (1.3.2) I was able to drag and drop the PSMTabBarControl to my Window and link it with the NSTabView (PSM - tabView - NSTabView && NSTabView - delegate - PSM), but after i tried a Demo (apple+r) I cant see the Tabs... Tried all I can - but dont know why.. Am I doing sth. wrong? Which other Framework or Source I can use to create Tabs like Firefox oder Safari? Thank you!

• VS2008: Disable asking whether to reload files changed outside the IDE

  - by SealedSun

  Hi, I have a Visual Studio 2008 project where some code files are generated with each build (a parser, integrated via MSBuild aka editing the *.csproj file). VS does not know about the generated nature of these files (i.e. they are not the result of a "Custom Tool). So they "change" with every build, naturally. And VS2008 asks me after every build if I would like to reload those files: This file has been modified outside the source Do you want to reload it? That would be ok if I had one of those files opened and in front of me, but I get these modal dialogs even with none of the code files opened. So my question is: Is there a way to disable this dialog, per project, per solution or globally? Thanks!

• WPF Dispatcher {"The calling thread cannot access this object because a different thread owns it."}

  - by user359446

  first I need to say that I´m noob with WPF and C#. Application: Create Mandelbrot Image (GUI) My disptacher works perfektly this this case: private void progressBarRefresh(){ while ((con.Progress) < 99) { progressBar1.Dispatcher.Invoke(DispatcherPriority.Send, new Action(delegate { progressBar1.Value = con.Progress; } )); } } I get the Message (Title) when tring to do this with the below code: bmp = BitmapSource.Create(width, height, 96, 96, pf, null, rawImage, stride); this.Dispatcher.Invoke(DispatcherPriority.Send, new Action(delegate { img.Source = bmp; ViewBox.Child = img; //vllt am schluss } )); I will try to explain how my program works. I created a new Thread (because GUI dont response) for the calculation of the pixels and the colors. In this Thread(Mehtod) I´m using the Dispatcher to Refresh my Image in the ViewBox after the calculations are ready. When I´m dont put the calculation in a seperate Thread then I can refresh or build my Image.

• Jquery: How can I place triggers on images already cached?

  - by FLX

  Please see: hxxp://flx.me/h/0504/ Source: hxxp://pastebin.com/bDh5k3Qd jquery.preload-min.js: hxxp://jquery.com/plugins/project/Preload jquery.jplayer.min.js: hxxp://www.happyworm.com/jquery/jplayer/0.2.4/developer-guide.htm I'm using jquery.preload-min.js to preload images and to send a play trigger to jquery.jplayer.min.js to start playing a mp3 file. This works great when viewing the page for the first time (or force reloading all content). However, when the image has already been cached, it doesn't use the preloading script and thus does not send the play trigger to jplayer. How can I make it send a play trigger even when the image is cached? Thank you in advance, Dennis

• Unable to reserve a job with beanstalkd

  - by Brian Hogg

  I have tried on two different servers to get beanstalkd up and running and do a couple tests (locally on MacOSX compiled from source, and on a CentOS server installed with yum) I can get the server running either with sudo beanstalkd -d -p 11300 or sudo beanstalkd -p 11300 & I then tried using the php lib and it just froze. Connecting directly: telnet localhost 11300 I do the following to mimic the PHP test script: use foo USING foo put 0 0 120 5 hello INSERTED 1 reserve-with-timeout 0 TIMED_OUT If I just run reserve It's stuck indefinitely. Any ideas?

• ADO "Unspecified Error" instead of actual error when fetching server side cursor

  - by Dan

  This relates to my recent question: http://stackoverflow.com/questions/2835663/force-oracle-error-on-fetch I am now able to reproduce a scenario where using ADO with the Oracle OLEDB Provider, I can force an error such as ORA-01722: invalid number to occur on calling Recordset.MoveNext However, this is not the error that is returned to the application. Instead, the application sees Provider error '80004005' Unspecified error. How can I get the application to see the real error from the database? This is with Oracle 10g (client and server), if it matters. Sample code is roughly as follows: Dim con As New ADODB.Connection Dim cmd As New ADODB.Command Dim rs As ADODB.Recordset con.ConnectionString = "Provider=OraOLEDB.ORACLE;Data Source=xxx;User Id=yyy;Password=zzz" con.CursorLocation = adUseServer con.Open Set cmd.ActiveConnection = con cmd.CommandText = "select * from table(ret_err)" cmd.Prepared = True Set rs = cmd.Execute While Not rs.EOF rs.MoveNext Wend

• What's the official Microsoft way to track counts of dynamic controls to be reconstructed upon Postback?

  - by John K

  When creating dynamic controls based on a data source of arbitrary and changing size, what is the official way to track exactly how many controls need to be rebuilt into the page's control collection after a Postback operation (i.e. on the server side during the ASP.NET page event lifecycle) specifically the point at which dynamic controls are supposed to be rebuilt? Where is the arity stored for retrieval and reconstruction usage? By "official" I mean the Microsoft way of doing it. There exist hacks like Session storage, etc but I want to know the bonafide or at least Microsoft-recommended way. I've been unable to find a documentation page stating this information. Usually code samples work with a set of dynamic controls of known numbers. It's as if doing otherwise would be tougher. Update: I'm not inquiring about user controls or static expression of declarative controls, but instead about dynamically injecting controls completely from code-behind, whether they be mine, 3rd-party or built-in ASP.NET controls.

• What helpful tactics have you employed to keep your development team on-track?

  - by Ed Altorfer

  I realize that this is a subjective question, so I've marked it as a community wiki. I think that it is pretty specific to programming teams, though, so I've posted it here as opposed to somewhere else. I'm leading a small game development team (four people) as a side project. We are a disjoint team, with everyone in different places, but we do have some of the mainstays of an organized team. Source Control Continuous Integration Bug Tracking Document Workspace Regular Meetings Calendar / Schedule How do you keep your small, disjoint teams on-track? I tend to agree with Joel's opinion about when and how to micromanage and know that my team is motivated, but it can be easy to fall off-course when everyone isn't connected in a physical way and doesn't see what other people on the team are doing. Suggestions, feedback, or criticisms are welcome! Edit: I'm managing the team; I'm not looking for automated tools or anything to do my job for me, just ideas for approach or process that might help everyone feel more "connected" and involved.

• Protect .NET assemblies from decomplie

  - by Holli

  One if the first things I learned when I started with C# was the most important one. You can decompile any .NET assembly with Reflector or other tools. Many developers are not aware of this fact and most of them are shocked when I show them their source code. Protection against decompilation is still a difficult task. I am still looking for a fast, easy and secure way to do it. I don't want to obfuscate my code so my method names will be a,b,c or so. Reflector or other tools should be unable to recognize my application as .NET assembly at all. I know about some tools already but they are very expensive. Is there any other way to protect my applications?

• Hex Decompilers for PIC

  - by Chathuranga Chandrasekara

  I've faced to a problem with a PIC Micro controller. I have a micro-controller programmed by me long time ago and I lost the relevant source code and the schematic diagrams. Now I need to invert the value of a port. I can do this using some NOT gates but it is a big hassle to do so. or alternatively I will need to write the whole program back. I don't expect to see the code back in PIC C or MikroC. Having an understandable assembly code would be sufficient. So do anyone has any experience on a good HEX decompiler that I can use for this purpose? Any comments based on your experience? :)

• Yet another php ereg fix

  - by casben79

  I have a small chunk of coding I need to take from ereg to preg_match. Here is the code. function be_file_list($d, $x) { foreach (array_diff(scandir($d), array('.', '..')) as $f) { if (is_file($d . '/' . $f) && (($x) ? ereg($x.'$',$f) : 1)) { $l[] = $f; } } return $l; } This code works as expected even if it doesn't look too pretty (source: http://www.php.net/manual/en/function.scandir.php) but as ereg is deprecated, I would really like to make it preg_match, or something like that. I have been messing with this all afternoon and the PC is about to go out the window. I would have thought that preg_match("/"$x.'$',$f"/") would have worked but no dice. Any help would be great.

• is it even possible to modify .apk, by adding additional class to .dex and re-packing with modified

  - by user355859

  is it even possible to modify .apk, by adding additional class to .dex and re-packing with modified manifest.xml?? I know there are tools such as baksmali / smali to disassemble / re-assemble given classes.dex from .apk, but not sure limitation what could be modified from there on? I'm trying to add additional activity, to modify starting launcher activity (may be from androidmanifest.xml) from original apk, then re-pack and sign to make complete single .apk... all need to be done out of build time, no raw source or build structure visible, only .apk as input... ANY IDEA?

• Matching .NET References to Namespaces

  - by maxp

  This seems confusing to me - im creating a class library, and adding all the necessary references for the source files contained in it. Now, off the bat, there were over 300 compiler errors complaining about missing namespaces. The library will now compile after i just added all of the System.* references, however this is obviously not the best way. I.e. if a classes needs using System.Web.Script;, there is no System.Web.Script reference, how would i find out which one of these references contained it? System.Web didnt.

• Store web content in XML using wiki markup

  - by Mike

  Does anyone have an XML style sheet that'll convert wiki-like markup to HTML? Or is that a bad idea? I only found one style sheet that'll convert HTML to wiki-like markup, view-source:http://mozile.mozdev.org/0.8/demos/html2wiki.xsl . Or is this a bad idea? Basically, instead of following strict rules with my XML tags to format my content, I thought it'd be best to have something like this: <content> \## This is my heading </content> That way I'm free to display my content however I feel without having to modify my style sheet. Any ideas?

• Debuging to simulator crashes with "exited with status 5" unless I debug

  - by tigermain

  For some reason the app I am working on has very bad PMT! Literally! Most of the time I cannot debug using the simulator without putting a breakpoint in my AppDelegate. If I don't it exists with "status 5". If I put a break point in and simple continue it works perfectly well, it also works if I run the app in the simulator when not connected to the GDB. I have tried the source on a second machine with exactly the same results. I dont have this issue building to the device?!?!?! Thanks
