• How to hide a Mono application on the OSX Dock

  - by Chris

  I have a Mono application that should not show on the dock, but will occasionally show a window. I want neither menu bar nor dock icon to show for this application. I have my application wrapped in an app bundle, and my info.plist file has the LSUIElement set to "1". This does not seem to be hiding my application from the Dock. I have tried also calling osascript with the following info in a Process.Start: osascript -e 'tell application "System Events" to set visible of process "myapp" to false' This returns a System Event error code: -10006. Thus far, I've had no luck finding out what that means. I've also tried all the standard Hide() and Visibility = false stuff inside Mono. Anyone found a workaround for this, or have an idea a direction I can look in? For the most part, working in Mono has been straightforward .Net coding, but this has me stumped.

• What is ltmain.sh, and why does automake say it is missing? What is a good auto (make/conf/etc) gene

  - by gersh

  I just want to develop a C app in linux with the auto(make/conf/...) stuff automatically generated. I tried generating it with ede and anjuta, but it doesn't seem to generate Makefile.am. So, I tried running automake, and it says "ltmain.sh" isn't found. Is there some easy to generate the basic build files for linux C/C++ apps. What is the standard practice? Do most people write these files themselves?

• LB_SETTABSTOPS does not appear to affect a CheckedListBox

  - by BP

  I am trying to set tab stops in a CheckedListBox in my WinForms application, but no matter what I do, it does not seem to have any effect. I have the following in the code for my form: <DllImport("user32.dll")> _ Public Sub SendMessage(ByVal hWnd As IntPtr, ByVal uMsg As Int32, ByVal wParam As Int32, ByRef lParam As Int32) End Sub Public Const LB_SETTABSTOPS As Int32 = &H192 And in the form's load method, I am doing the following, where theList is my CheckedListBox: Dim tabStops() As Integer = {40, 140, 240} Call SendMessage(theList.Handle, LB_SETTABSTOPS, tabStops.Length, tabStops(0)) theList.Refresh() And then later on, I use this in a loop, where col1 through col4 are all string values for the columns: theList.Items.Add(col1 & vbTab & col2 & vbTab & col3 & vbTab & col4) But no matter what I use for the values of tabStops, the list is formatted with standard width tab stops.

• How to sound audible bell from crontab

  - by user1526251

  The command line: /bin/echo -e "\007" in bash will ring the bell. With the line: /bin/echo -e "\007" in my crontab I expected the bell to ring every minute, but it's silent. I know crontab is working because the line: /bin/touch $HOME/jkjkjk updates the file jkjkjk every minute as it should. I found a posting some years ago suggesting that standard output should be directed to /dev/tty1 in crontab. But the line: /bin/echo "\007" /dev/tty1 Still fails. What to try next?

• Vehicle 2 Vehicle Communication Questions

  - by pinnacler

  I have a rare opportunity to meet the man in charge of implementing vehicle 2 vehicle communication for the US Department of Transportation with 2 others in a few hours. Do YOU have any questions for him? I know this is a little outside the normal, but this is a 'reverse' thread and I felt he has some great knowledge on the subject that I want to share with this community. I'll post his answers later today to his questions. Ask about V2V implementation, privacy issues, use cases, or if you've thought of a great way to use V2V and want me to share it with him, he can at least think about it. He is in charge of panel that creates the standard. Or anything else...

• Entity framework error: The conversion of a datetime2 data type to a datetime data

  - by EdenMachine

  I know there are a ton of posts about this issue but none of them seem to solve my problem. Here's the scenario: I have a CreateDate DateTime column in my MS SQL Server database User table that is non-nullable and is automatically set using GetDate() method in "Default Value or Binding" setting. I am able to create a User just fine with the standard EF Insert but when I try to update the user, I get this error: The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value. What is the trick to not having the EF worry about the CreateDate column for updates? I have the StoreGenerationPattern = Identity but that isn't helping. Here are the EF properties for my Entity Property: http://screencast.com/t/8ndQRn9N And here is my Update method: http://screencast.com/t/UXIzhkhR

• Adding links to full change forms for inline items in django admin?

  - by David Eyk

  I have a standard admin change form for an object, with the usual StackedInline forms for a ForeignKey relationship. I would like to be able to link each inline item to its corresponding full-sized change form, as the inline item has inlined items of its own, and I can't nest them. I've tried everything from custom widgets to custom templates, and can't make anything work. So far, the "solutions" I've seen in the form of snippets just plain don't seem to work for inlines. I'm getting ready to try some DOM hacking with jQuery just to get it working and move on. I hope I must be missing something very simple, as this seems like such a simple task! Using Django 1.2.

• How to disable listbox's click event

  - by StupidDeveloper

  I have a listbox which acts as a list of items. If you click on some item, it's contents are shown in the panel on the right (few textboxes etc.). I need to have a validation on these controls as all of them are required fields. And I do have it. The problem is that, even when the validators are not valid, user can click the listbox and change active index (that doesn't have impact on the panel on the right, as SelectedIndexChanged isn't fired). The validators are standard RequiredFieldValidator with their Display property set to "Dynamic". So, what I want is to disallow the user clicking on the listbox and changing the index untill all validators are Valid. What would be your solution for that? Is that even possible?

• How can I use a Shader in XNA to color single pixels?

  - by George Johnston

  I have a standard 800x600 window in my XNA project. My goal is to color each individual pixel based on a rectangle array which holds boolean values. Currently I am using a 1x1 Texture and drawing each sprite in my array. I am very new to XNA and come from a GDI background, so I am doing what I would have done in GDI, but it doesn't scale very well. I have been told in another question to use a Shader, but after much research, I still haven't been able to find out how to accomplish this goal. My application loops through the X and Y coordinates of my rectangular array, does calculations based on each value, and reassigns/moves the array around. At the end, I need to update my "Canvas" with the new values. A smaller sample of my array would look like: 0,0,0,0,0,0,0 0,0,0,0,0,0,0 0,0,0,0,0,0,0 1,1,1,1,1,1,1 1,1,1,1,1,1,1 How can I use a shader to color each pixel?

• strod() and sprintf() inconsistency under GCC and MSVC

  - by Dmitry Sapelnikov

  I'm working on a cross-platform app for Windows and Mac OS X, and I have a problem with two standard C library functions: strtod() (string-to-double conversion) ? sprintf (when used for outputting double-precision floating point numbers) -- their GCC and MSVC versions return different results. I'm looking for a well-tested cross-platform open-source implementation of those functions, or just for a pair of functions that would correctly and consistently convert double to string and back. I've already tried the clib GCC implementation, but the code is too long and too dependent on other source files, so I expect the adaptation to be difficult. What implementations of string-to-double and double-to-string functions would you recommend?

• iPhone – How to import/drawing UI graphic elements? CGContextDrawPDFPage?

  - by Ross

  Hello, What is the best way to use the custom UI graphics on the iPhone? I've come across CGContextDrawPDFPage and Panic's Shrinkit. Should I be using storing my vector ui graphics as PDF's and loading them using CGContextDrawPDFPage to draw them. I did previously asked what way Apple store their UI graphics and was answered crushed png. The options as I see it, but I would really want to know what technique other people use. This question is for vector graphics only. Looking for what is standard / most effective / most efficient. PNG (bitmapped image) Custom UIView drawing code (generated from Opacity) PDF (I've not used this method, is it with CGContextDrawPDFPage?) Many thanks Ross

• #if 0 as a define

  - by valerio

  I need a way to define a FLAGS_IF macro (or equivalent) such that FLAGS_IF(expression) <block_of_code> FLAGS_ENDIF when compiling in debug (e.g. with a specific compiler switch) compiles to if (MyFunction(expression)) { <block_of_code> } whereas in release does not result in any instruction, just as it was like this #if 0 <block_of_code> #endif In my ignorance on the matter of c/c++ preprocessors i can't think of any naive way (since #define FLAGS_IF(x) #if 0 does not even compile) of doing this, can you help? I need a solution that: Does not get messed up if */ is present inside <block_of_code> Is sure to generate 0 instructions in release even inside inline functions at any depth (i guess this excludes if (false){<block_of_code>} right?) Is standard compliant if possible Thank you

• Restart IIS7 webapp for debug in VS2008

  - by spender

  I'm developing an ASP.NET asyc generic handler which uses a static System.Threading.Timer instance to feed data to the response output stream while the context is in the asynchronous phase. I'm having issues at startup that I'd like to debug. Currently, because of the long-lived nature of the timer, I'm manually killing w3wp.exe in order to cause the application to restart. I'm aware that there are other ways to do this, but this is the best workflow I can find! Isn't there a way to force a cold start when I hit f5, instead of the standard VS approach of attaching to the existing IIS process?

• Externalize Javascript in YAP

  - by Haseeb Khan

  I am working on a Yahoo! App which requires certain external Javascript Frameworks to be loaded and used. Also in the Yahoo! App Best Practices Guide, it is also mentioned that the sources should be externalized, however, externalization isn't working for me. I am using the standard procedure to load the external JS file like the following: <script src="http://www.google.com/js/nxsl.1.js"></script> But the above statement is giving me an error that external sources are not allowed. Is there any way to use external JS files as I don't want to include all of my JS Login inline, it doesn't make sense to me and majorly my code won't be re-usable. Any thoughts ?

• Codeigniter: Combining activeRecord with manual queries?

  - by Industrial

  Hi everybody, I've though a bit about the activerecord vs. manual queries in Codeigniter. ActiveRecord is awesome when it's all about standard queries and holds development time really low. However, when there's a need to add some complexity to the queries, the ActiveRecord gets quite complicated to work with. Sub queries or complex joins gives atleast me a lot of headache. Since the current "$this-db-query" -call immediately executes the set query, it can't be combined with normal activeRecord calls. So, what can I do to combine the two methods? Thanks!

• Ambiguous reference when getter/setter have different visibilities

  - by Warren Seine

  The following code raises an ambiguous reference to value at compile time: import flash.display.Sprite; public class Main extends Sprite { private var _value : Number = 0.; public function get value() : Number { return _value; } private function set value(v : Number) : void { _value = v; } public function Main() : void { value = 42.; } } I suspect some kind of bug in the compiler, though I didn't actually read the ECMA standard. Before someone asks those questions: Private setters do make sense. The ambiguity also exists with custom namespaces (which is the problem I'm facing).

• Best way to reuse a footer menu in Android

  - by Gunnar Lium

  I'm trying to implement a menu in the footer of an app, similar to i.e. the Engadget app. As I understand, getting a standard TabLayout to work in this way is not trivial (if at all possible?). As I see quite a few apps using this interface paradigm, I would assume there is a clever way of doing it. Currently, I'm defining the layout by adding an include line at the end of every layout. This works fine as far as rendering is concerned, but I have to add the onClickListeners to each activity. can we define clickListener through XML? To sum up my question: What is the best way to implement a shared footer navigation accross several Activities?

• python: iif or (x ? a : b)

  - by Albert

  If Python would support the (x ? a : b) syntax from C/C++, I would write: print paid ? ("paid: " + str(paid) + " €") : "not paid" I really don't want to have an if-check and two independent prints here (because that is only an example above, in my code, it looks much more complicated and would really be stupid to have almost the same code twice). However, Python does not support this operator or any similar operator (afaik). What is the easiest/cleanest/most common way to do this? I have searched a bit and seen someone defining an iif(cond,iftrue,iffalse) function, inspired from Visual Basic. I wondered if I really have to add that code and if/why there is no such basic function in the standard library.

• Increase file upload size limit in iis6

  - by JustFoo

  Is there any other place besides the metabase.xml file where the file upload size can be modified? I am currently running a staging server with IIS6 and it is setup to allow uploading of files up to 20mb. This works perfectly fine. I have a new production server where I am trying to setup this same available size limit. So I edited the metabase.xml file and set it to 20971520. Then I restarted IIS and that didn't work. So I then restarted the entire server, that also didn't work. I can upload files around 2mb so it is definitely allowing file sizes larger then the standard 200kb default size. I try uploading a 5mb file and my upload.aspx page completely crashes. Is it possible there is something else I need to configure? The production server is located on a server farm, could there be some limits set on there end? Thanks

• Verify mail server connection programmatically in ColdFusion

  - by Sergii

  I'm using custom SMTP servers and would like to verify the connection when user enters his own server credentials. Exactly the same type of check as Adobe CF and Railo allow to do when adding mail server. Sure, this does not guarantee that delivery will be working, but at least to check that entered server/username/pass are valid. I can see one tricky way: try to send the email with cfmail and check the mail log. But I believe that it can be done with more elegant. Is there any Java library available with standard ACF/Railo distro to help me? How would I use them? Examples are highly appreciated. Thanks in advance. EDIT: Please don't be confused with Java tag present. Solution needed in CFML. Though it can use some Java libraries, if applicable.

• ASP.NET MVC on IIS6

  - by Seb Nilsson

  Where can I find some good pointers on best practices for running ASP.NET MVC on IIS6? I haven't seen any realistic options for web-hosts who provide IIS7-hosting yet. Mostly because I don't live in the U.S. So I was wondering on how you best build applications in ASP.NET MVC and make it easily available to deploy on both IIS6 and IIS7. Keep in mind that this is for standard web-hosts, so there is no access to ISAPI-filters or special settings inside IIS6. Are there anything else one should think about when developing ASP.NET MVC-applications to target IIS6? Any functions that doesn't work? UPDATE: One of the bigger issues is the thing with routes. The pattern {controller}/{action} will work on IIS7, but not IIS6 which needs {controller}.mvc/{action}. So how do I make this transparent? Again, no ISAPI and no IIS-settings, please.

• Is it acceptible to expect mentoring to replace many years experience?

  - by Mantorok

  Hi all Just a quick question Here's my situation: I've been maintaining, extending and creating websites against a CMS for the last 18 months In that time I've learnt a LOT more about ASP.Net, javascript, and of course the quirks of the CMS we are using My manager wants to get others involved, and I'm expected to mentor another programmer whilst they work on production code Now, I've got no problem mentoring someone and it would be great for me to not be the only one with the skillset. But what I HAVE got a problem with is mentoring someone within an agreed timescale of the piece of work (10 days in this case) AND expected to deliver the product to the same standard. I guess what I'm getting at is: 18 months experience != a few days mentoring, not to mention the level of C#/.Net/ASP.Net/Javascript required may also not be up to scratch. Am I right to think this is a little, wrong?

  I'm porting android to Devkit8000 which is a BeagleBoard clone. I have a GPS module connected on /dev/ttyS0. I could successfully get NMEA output when writing "cat /dev/ttyS0" in the terminal emulator. I want to know how to let android know that there is a GPS module on /dev/ttyS0 and it is outputting NMEA standard? To be able to use the android.location class with it! Is there something to edit in the android's source? adding driver for example, writing a code with android-ndk or what?

• How to prepare for a Java test?

  - by Zenzen

  Ok so in two days I have a test for my dream job (well it's an internship, but still!) and for quite some time now I've been reading the SCJP Guide book in order to prepare myself. BUT seeing how slow my reading speed is I guess finding a website with some "java essentials" or "standard java test questions" and going through it in those 2 days would be a better idea. Don't misunderstand me, I do have java experience and it's "only" an internship, but we all know how programming tests look like and how tricky they can be. So are there any online resources you could recommend me? I know 2 days is not much, but well I was informed bout the test 1-2days ago.
