• Google Maps - user to pinpoint a location

  - by JohnB

  Hi, Is it possible to allow users of my website to mark places on a map I display using Google Maps API? I need to then save that location coordinates to a db. I've been looking through the google maps API, I found that I can use the web service to do searches like this: http://maps.google.com/maps/geo?q=Maine,+United+States&output=json&oe=utf8\&sensor=false&key=my_key But I am not sure it's working on a house number level (which I need it to) and I'm not sure how to display a 'did you mean?' to the user when he misspells the address.. Anyone have an idea? Thanks,

• Understanding the output from svn export

  - by ThatBlairGuy

  Working on some tweaks for a build script, I noticed that the output from svn export has an 'A' in column 1 for each file exported. A C:\build\file1 A C:\build\file2 A C:\build\file3 The subversion book describes the meaning of the various columns for svnlook changes and svn status, but I'm not having much luck finding the meaning behind this one. What does the 'A' in column 1 mean? Are there any other values displayed there? Any other columns? Thanks!

• "The breakpoint will not currently be hit. The source code is different from the original version."

  - by David

  Hi everyone I'm really hoping someone can help me out with this one. When debugging in Visual Studio, sometimes I add a breakpoint but it's hollow and VS says "The breakpoint will not currently be hit. The source code is different from the original version." Obviously this prevents me being able to debug. What on earth does the message mean? What original version? If I've just opened up the solution and not made any changes whatsoever to the code, how can there be an 'original version'? The appearance of this problem just seems totally arbitrary. It's just Visual Studio going 'Na na na na na, I'm not going to debug for you today'. Can anyone give any advice? Ta David

• How to load one div into another.

  - by Vinodtiru

  Hi, I have a page with 10 different div contents in it. Based on my button click i want the 11th div to load content or just take a copy of div 1 to 10. I mean like on button1 it should load div 1 and on button 2 i will load div 2 etc. All my div 1 to 10 will be hidden and the 11th div alone will be visible. I need this because of my below hierarchy. - Main Page (having the 10 div) ->inner div which is loaded by a ajax request.(this has 11th div and buttons) Now on click of any button like 1 to 10 its respective divs is supposed to be loaded from the div in the main page. I would like to do this by java script or jquery. Please let me know any possibilities. Any kind of suggestions or solutions is appreciated.

• Run a pool of processes in shell

  - by viraptor

  I'm looking for an easy method to run N selected processes at the same time with one command. It should put all the output on my terminal and shut down all of them when I exit with ctrl+c. Is there any existing app that does this? I'm thinking of some thing like exec_many 10 foo - it should keep 10 foos running and respawn any that dies.

How can I pass the list and dictionary as parameters? Added func(10,20, 10,20,30, k='a') seems to be working

• How to open window pop-up from Silverlight Out-of-Browser?

  - by Jeaffrey Gilbert

  I need to open window pop-up from Silverlight Out-of-Browser application. I've added parameter <param name="enablehtmlaccess" value="true" /> in Index.html, but executing this from code behind: HtmlPage.Window.Navigate(new Uri(myUrl), "_blank", myFeatures); still returns error: Silverlight OOB Error: The DOM/scripting bridge is disabled. I've read about this post, does it mean that I can't open pop-up from OOB? Why I need to do this, because actually I've shown the HTML page in OOB Silverlight by WebBrowser control within ChildWindow but when I click an anchor in HTML page, which linked to _blank page, it jumps to my default browser. It doesn't meet the requirement, except launch that HTML index page also in default browser at the first time, triggered from button control in OOB Silverlight. Is that possible? Please advice, thanks.

• Enter Password in C

  - by Mohit Deshpande

  I am aware that it is not possible to echo the * while you type in standard ANSI C. But is there a way to display nothing while someone is typing their password in the console. What I mean is like the sudo prompts in a Unix/Linux terminal. Like if you type in the command: sudo cp /etc/somefile ~/somedir. You are usually prompted for the root password. And while you type it in, the terminal displays nothing. Is this effect possible in C? If it is, how?

• c# compact-framework textbox mouseleave

  - by arnoldino

  hello, I would like to leave the textbox via code. when user clicks in the textbox, and types in something , and then the user will click outside the textbox. on the screen there are just labels. only this one textbox is on the form. my problem is, that the textbox does not lost focus when I click everywhere on the screen. the texbox it still has the focus. this textbox is used to filter a list, built from labels. the complete story is: - I have no mainmenu on the screen, so the Sip icon is not visible - user clicks in the textbox, and i bring up the SIP, in the textbox.GotFocus event - user types in some letters, the list is filtered - if user clicks away, the SIP disappears (textbox.lostfocus), but the textbox still has the focus, I mean the cursor remains in the textbox - when user wants to type some other letters for filtering, it clicks in the textbox, but GotFocus does not fire how can I make the texbox to loose the focus?

• Graphical Programming Language

  - by prosseek

  In control engineering or instrumentation, I see Simulink or LabVIEW(G) is pretty popular. In ESL design, I see that Agilent SystemVue is gaining some popularity. If you see the well established compiler theroy, almost 100% is about the textual language. But how about the graphical language? Is there any noticable research or discussion about the graphical programming language? In terms of Theory about Graphical Language - syntactic/semantic analysis and whatever relevant expressiveness (Actually, I asked a question about it at SO - http://stackoverflow.com/questions/2427496/what-do-you-mean-by-the-expressiveness-in-programming-lanuguage) Possibility of the Graphical language ... Or what do you think about the Graphical Programming Language?

• How to cycle through matrix blocks?

  - by luiss

  I have some matrix which I want to cycle through blocks, the matrix could be of many different sizes, but I can know the size, is there a way to fast cycle through blocks? i.e: to fast output the indexes of the blocks, suppose a matrix of 4*4 I should have: Block1: (0,0),(0,1)(1,0)(1,1) Block2: (0,2),(0,3)(1,2)(1,3) Block3: (2,0),(2,1)(3,0)(3,1) Block4: (2,2),(2,3)(3,2)(3,3) Where the indexes are (row,col). For blocks I mean a submatrix of size sqrt(matrixSize)* sqrt(matrixSize) where matrix is a matrix of matrixSize*matrixSize. For example a matrix of 4*4 has 4 blocks of 2*2, a 9*9 has 9 blocks of 3*3... I'm workdeing in C, but I think that the pseudocode is useful also, I only need the loop on the indexes... Thanks

• Turn off backlight without X server commands

  - by Vi

  Fn + F6 - backlight turns off immediately, image stays (visible if shine something at the display) xset dpms force {off,suspend,standby} - backlight turns off slowly, image cleared. How to programmatically just turn off backlight on Acer Extensa 5220 laptop in Linux? It should work fast and should not touch image (unlike xset method). Ideally if I could rapidly switching backlight off and on emulate lower_than_minimum brightness level (ideally - to be hardly visible (but visible) at night).

• printf field width : bytes or chars?

  - by leonbloy

  The printf/fprintf/sprintf family supports a width field in its format specifier. I have a doubt for the case of (non-wide) char arrays arguments: Is the width field supposed to mean bytes or characters? What is the (correct-de facto) behaviour if the char array corresponds to (say) a raw UTF-8 string? (I know that normally I should use some wide char type, that's not the point) For example, in char s[] = "ni\xc3\xb1o"; // utf8 encoded "niño" fprintf(f,"%5s",s); Is that function supposed to try to ouput just 5 bytes (plain C chars) (and you take responsability of misalignments or other problems if two bytes results in a textual characters) ? Or is it supposed to try to compute the length of "textual characters" of the array? (decodifying it... according to the current locale?) (in the example, this would amount to find out that the string has 4 unicode chars, so it would add a space for padding).

• WinForms app config manager is x86 and cannot reference assemblies that targets Any CPU

  - by ivos

  Hi I'm using Win7 64x and Visual Studio 2010. I created a library/framework targeting Any CPU. Then I created a new WinForms project that uses that framework, leaving the default values of the wizard. I mean, I didn't change anything. When I reference my framework, VS cannot find the assemblies. If I go to the project properties, it is targeting Any CPU (as expected, I can change it if I want). But if I go to Configuration Manager, the only choice I have for that project is x86. And I guess that is the problem. I tried to add Any CPU as a new Target but I was unable to. Could someone help me? :) Thanks in advance!

• In C#, how do you send a refresh/repaint message to a WPF grid or canvas?

  - by xarzu

  How do you send a refresh message to a WPF grid or canvas? In other words, I have noticed while in debug mode, I can write code that sends a line to the display and then, if that line is not right, I can adjust it -- but the previous line is still there. Now, the code I am writing sends information to the display based on what the user clicks. So this must mean that the display is not refreshed each time a new set of lines and boxes and text goes to the grid or canvas in WPF. Using C# code, how do you send a refresh/repaint message to a WPF grid or canvas?

• Building Asp.net Page code behind correctly

  - by Hagai

  Hi everyone, I need some guidelines about building the code behind of my pages correctly. I mean, I'm building in asp.net for a year now, and mostly using the Page_Load event. (and ofcourse "event handling" the events triggered by the user's actions). I know about the page life cycle and the order of events that happens when a page is requested etc.. . Is it normal that, generally, in a data-driven page, for example, I'm not using any of the "pre_render", "page_unload", "pre_init" etc.. event handlers? or am I missing something here? any guidelines would help me a lot, including links or whatever you think that would instruct me well. thanks.

• Default login popup for web sites

  - by John Quest

  Hi. I am trying to build a web site with ASP.NET MVC, I'm new to this. My question is: how can I display the default login dialog? I am not referring to a custom dialog, like the jQuery Dialog, there is a default pop-up for credentials, which looks different depending on browser, same as with javascript alert(), but I don't know how to display it. To know what I mean, go to http://fit.c2.com/wiki.cgi?WelcomeVisitors, there is a Login button at the bottom of the page, when you click it a pop-up appears. That is what I want to display. Any ideas?

• Default Database Collations PenTesting Env

  - by dominicdinada

  I am using Ubuntu 9.10 with XAMPP ( Lampp "MYSQL 5.1.45 PHPMYADMIN 3.3.1 PHP 5.3.2 ) What my problem is, is that I set up my testing env to debug my scripts locally and when I did so there arose a problem. This problem is that I used firefox's addon SQLinject ME to test for weakness' and upon doing so it caused mysql to change the default local collations; character sets dir /opt/lampp/share/mysql/charsets/ collation connection latin1_general_ci (Global value) latin1_swedish_ci collation database latin1_swedish_ci collation server latin1_swedish_ci I have searched for quite sometime in regards to a solution to this problem and have come up with searching for the db.opt file which stores this information without success. Upon not finding a solution I removed lampp with the "sudo rm -fR /opt" command and reinstall and the problem still persists. I have tried to change the collations manually and still come up with the database displaying latin1_swedish_ci as the default language. Why is this a problem?? Why is it a problem with mysql? Because the application I am testing and debugging locally is built on the CodeIgnitor with Smarty framework and since this combination of framework is built to detect the LOCALES, Rather what the database defaults are I keep getting errors saying no language file for swedish...... Of course I could get the swedish language file to work around this problem but I do not feel the need to make this work around a perminant solution as with time when I move on to projects I will run into simular problems every time that A; When importing database files, backups etc it will default to import such databases as the locale swedish. B; As time passes on I might completly forget of this error and will be back to square one. I have found this code in searches for a fix,which seems to alter the tables to a desired Collaion; $value) { mysql_query("ALTER TABLE $value COLLATE latin1_general_ci"); }} echo "The collation of your database has been successfully changed!"; ? Which is handy to switch collations in One Schema at a time however this is not a fix when a framework doesnt care that the said database is in one langugae. It tests for the Default of the entire server. Someone with any knowledge of a purge or fix to this I would greatly appricate the help. One more final note is that when I was testing I only figured to back up the applications DataBase and not the entire Schema of the install. No matter if I uninstall or reinstall the database still seems to carry these problems.

• Do MyISAM holes get filled in automatically?

  - by NNN

  When you run a delete on a MyISAM table, it leaves a hole in the table until the table is optimized. This affects concurrent inserts. On the default setting, concurrent_inserts only work for tables without holes. However, in the documentation for MyISAM, under the concurrent_insert section it says: Enables concurrent inserts for all MyISAM tables, even those that have holes. For a table with a hole, new rows are inserted at the end of the table if it is in use by another thread. Otherwise, MySQL acquires a normal write lock and inserts the row into the hole. http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_concurrent_insert Does that mean MyISAM automatically fills in holes whenever a new row is insert into the table? Previously I thought the holes would not be fixed until you OPTIMIZE a table.

• Inheriting from the web client class

  - by robUK

  Hello, C# 2008 I am not sure how much work there is to inheriting from the web client class. Currently I am using it in my project. And I can't change to anything else. The customer would like to have a timeout after a certain period of time. The web client doesn't have this. So rather than re-invent the wheel, I am thinking of inheriting from the web client and adding this property. Do you think this is a suitable solution? Could it mean more work just to add this. What is the easiest way to go about this? Many thanks,

• Reused UIWebView showing previous loaded content for a brief second on iPhone

  - by Roi

  In one of my apps I reuse a webview. Each time the user enters a certain view on reload cached data to the webview using the method - (void)loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)encodingName baseURL:(NSURL *)baseURL and I wait for the callback call - (void) webViewDidFinishLoad:(UIWebView *)webView. In the mean time I hide the webview and show a 'loading' label. Only when I receive webViewDidFinishLoad do I show the webview. Many times what happens is I see the previous data that was loaded to the webview for a brief second before the new data I loaded kicks in. I already added a delay of 0.2 seconds before showing the webview but it didn't help. Instead of solving this by adding more time to the delay does anyone know how to solve this issue or maybe clear old data from a webview without release and allocating it every time?

• Code Profiling in the Windows Sidebar Environment

  - by Matt

  Does anyone know of a way I can code-profile my Windows Sidebar Gadget? I've played around with the code-profiling tool in IE8's "Developer Tools" and the code-profiling included in Visual Studio 2010, but I can't find a way to include the System.* API, which my gadget relies on (as it is standard in the Sidebar environment). The gadget also relies on cross-domain AJAX requests; which is normally permitted in the Sidebar environment. By code-profiling I primarily mean: Function call count Function execution time Any ideas would be much appreciated. Regards, Matt

• Vim + OmniCppComplete: Completing on Class Members which are STL containers

  - by Robert S. Barnes

  Completion on class members which are STL containers is failing. Completion on local objects which are STL containers works fine. For example, given the following files: // foo.h #include <string> class foo { public: void set_str(const std::string &); std::string get_str_reverse( void ); private: std::string str; }; // foo.cpp #include "foo.h" using std::string; string foo::get_str_reverse ( void ) { string temp; temp.assign(str); reverse(temp.begin(), temp.end()); return temp; } /* ----- end of method foo::get_str ----- */ void foo::set_str ( const string &s ) { str.assign(s); } /* ----- end of method foo::set_str ----- */ I've generated the tags for these two files using: ctags -R --c++-kinds=+pl --fields=+iaS --extra=+q . When I type temp. in the cpp I get a list of string member functions as expected. But if I type str. omnicppcomplete spits out "Pattern Not Found". I've noticed that the temp. completion only works if I have the using std::string; declaration. How do I get completion to work on my class members which are STL containers? Edit I found that completion on members which are STL containers works if I make the follow modifications to the header: // foo.h #include <string> using std::string; class foo { public: void set_str(const string &); string get_str_reverse( void ); private: string str; }; Basically, if I add using std::string; and then remove the std:: name space qualifier from the string str; member and regenerate the tags file then OmniCppComplete is able to do completion on str.. It doesn't seem to matter whether or not I have let OmniCpp_DefaultNamespaces = ["std", "_GLIBCXX_STD"] set in the .vimrc. The problem is that putting using declarations in header files seems like a big no-no, so I'm back to square one.
