• why message box is always hidden behind main dialog and cannot be shown on the top

  - by Cougar_usa

  I am using MFC to write a GUI application. I chose dialog-based application, and put picture control, edit box and buttons on it. When the picture control is mapped to the class derived from CWnd using DDX_Control, all the message boxes (including default system message box pop up when you enter invalid input in the edit box) are hidden behind main dialog until you use "alt + tab" to bring them to front. If I map the picture control to the default CStatic class, the above problem disappeared. Do anyone has some hints to solve this problem? Thank you in advance for any help.

• How to print absolute line number in uncaught exception?

  - by DSblizzard

  When error occured Python prints something like this: Traceback (most recent call last): File "<stdin>", line 2, in <module> File "<stdin>", line 8, in m File "<stdin>", line 5, in exec_st File "<stdin>", line 9, in exec_assign File "<stdin>", line 48, in ref_by_id IndexError: list index out of range where 2, ... , 48 are relative line numbers which are not very convenient. How to print absolute line numbers in such error messages? EDIT: Maybe it's a dumb question, but answer will facilitate development a little. I'm printing text in several files. When done, press shortcut which runs python and copies contents of current file to console. Proposed solution forces to press excess keystrokes (Ctrl+S, Alt+Tab) and create additional files. I hope I have put it clear.

• rails 3 cookies

  - by ralph

  I have a simple app where users type in stuff in a text filed to get various results. I would like a feature where if a user enters something and then closes the browser tab, the next time they come, I can show them their previous/recent searches. This will persist even if they close the whole browser and open it again. I believe this can be done by help of cookies. Are there some good rails3 gems for using cookies or any simple tutorial that could guide me in a direction?

• Adding image to navigation bar

  - by 4thSpace

  I'd like an image to take up all of a navigation bar. This is the navigation that comes with a navigation based app. It appears on the RootViewController with the accompanying UITableView. I've seen some examples of how this might work. Set navigation bar title: UIImage *image = [UIImage imageNamed:@"TableviewCellLightBlue.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; [self.navigationController.navigationBar.topItem setTitleView:imageView]; The problem there is it only covers the title rather than the entire navigation bar. There is also this thread: http://discussions.apple.com/message.jspa?messageID=9254241#9254241. Towards the end, the solution looks to use a tab bar, which I'm not using. It is that complicated to set a navigation bar background? Is there some other simpler technique? I'd like to have a background for the navigation and still be able to use title text.

• Creating standalone, console (shell) for domain-specific operations

  - by mr.b

  Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

• VS 2010: Can't insert snippet using shortcut - incompatibility with resharper 5???

  - by mark smith

  Hi there, i recently installed some snippets that come with a framework i am using. And sure enought i checked via Tools > Code Snippet Manager and they are installed under "My Code Snippets". If i do insert Snipper (right click in code window) or CTRL K + CTRL X then i can search within all available snippets.... But i do believe its possible to just type the shortcut key (in this case it is mvvmlocatorproperty) and pressing tab inserts the snippet BUT when i type the shortcut key it is not recognizing anything... What am i doing wrong?? This is not an incompatibility with resharper 5? - which i have installed Any ideas really appreciated

• Missing prop-base file problem

  - by Tony

  I am using Eclipse and SVNSubversion as a repository for a Java project. After updating the local repository and starting Eclipse, an error (in the Problems tab) appeared stating that a specific prop-base file was missing from the build path. Being inexperienced, I have accidentally deleted the prop-base file icon from the project build-path library section. Since then the numbers of errors have grown exponentially... What should I do? Updating the local repository and/or starting a new Eclipse project from the same source did not solve the problem, does anyone have an idea?

• preventing window blur/focusOut when selecting copy/paste menu

  - by jedierikb

  I am trying to determine when the user has moved focus out of the browser to: select copy/paste (but not to the google search box). Ffox handles this nicely. selecting another window/tab/external widget (e.g., the google search box). focusOut and blur listeners on window and document cannot seem to disambiguate between these two types of focus changes. Can IE do this? I want this distinction so that I can better support usability in my web app without losing focus.

• PHP code in Drupal 6

  - by abhishekgupta92

  A very standard example of the problem that I am facing is that of a custom content say blog type. Now there is a view namely "My Blog Posts". In that view i take the argument as User:uid. Now, for the link part i simply write the code below: global $user; and send $user-uid as the argument to User:Uid. This give me link for "My Blog Posts" or the blog posts of the logged-in user What I want is a view like "His Blog Posts". So, if i visit the profile of some other user. There should be a tab in his profile "Blog Posts by Me". So for that i need to have the UID of the user whose profile I am visiting. So, how can I get this parameter from URL of his profile or somevhere else.

  I have downloaded the Websphere 2.1 App Server and verified that it works fine. I now wanted to use eclipse EE to manage it by adding the server to the server tab. Everything seems to work fine when going through the setup but when I go to start the server I get the error message: ERROR [GBeanInstanceState] Error while starting; GBean is now in the FAILED state: abstractName="org.apache.geronimo.framework/j2ee-system/2.1.4/car?ServiceModule=org.apache.geronimo.framework/j2ee-system/2.1.4/car,j2eeType=AttributeStore,name=AttributeManager" java.io.IOException: Unable to write manageable attribute files to directory /opt/IBM/WebSphere/AppServerCommunityEdition/var/config at org.apache.geronimo.system.configuration.LocalAttributeManager.ensureParentDirectory(LocalAttributeManager.java:573) at org.apache.geronimo.system.configuration.LocalAttributeManager.load(LocalAttributeManager.java:327) ....

• count(*) is it really expensive ?

  - by Anil Namde

  I have a page where i have 4 tabs displaying 4 different reports based of different tables. Now i get row count of each tabled using select count() from table query and display number of rows available in each table on the tabs. Now with each page post back 5 count() queries are executed (4 to get counts and 1 for pagination) and 1 query for getting report. Now my question is should is count(*) query really expensive that i should keep the row counts (at least which are displayed on tab) in view state of page instead of queering each time? How much expensive it is ?

• Dynamic instant theming a la My Yahoo / iGoogle

  - by Alex Neth

  I can think of lots of ways to do this on my own, but I was hoping to find some sort of best practice and have been having trouble finding other's experiences. I want to create easily themed HTML and provide a real-time selector for the user to experiment with themes. I want to do something like the "Change Appearance" tab at http://my.yahoo.com . I'll be using jQuery. jQuery has a "theming" system, but it seems very much focused on jQuery widgets as opposed to the whole site, and also doesn't appear to address the real-time selection aspect (the jQuery page has this functionality, but I don't think it's part of the library.) Maybe there is a jQuery plugin that already does this? Or some sort of css/jQuery framework?

• iphone sdk: Table view not working in the first 5 tabs but in the more view

  - by LHT

  Hi, I only started with sdk but this problem is bugging me now for a view days: I created a UITableView and added it to my Tabs. When this TableView is in the first 4 Tabs and u go look at it, it only shows the items on the table but when clicking on them nothing happens (it doesn't go to the next view). BUT when i put this same tab behind the 5th so it goes in the automatic MORE view everything works fine. I'm assuming this is because this more view is implementing some kind of table class. But i can't figure it out. I compared all the files with a working example but it seems to be all the same. ah ya my current project is a window based application. Though i copied most of the code from a navigation based application. Any ideas?

• How can I identifying control characters in Perl?

  - by sganesh

  I want to implement the command line features like in a linux terminal. I saw this in ftp command also. If I press tab I need to list the commands. If I press control characters I need to get that characters based on that I will do some action. And if I give any commands it should execute. For this I tried with Term::ReadKey that is in non-canonical mode. But here I am facing more problems like if I press any control character or arrow I got three characters. For the up arrow I got ASCII 27 91 65. Can anyone help me out of this problem?

• Best way to store data for Greasemonkey based crawler?

  - by Björn

  I want to crawl a site with Greasemonkey and wonder if there is a better way to temporarily store values than with GM_setValue. What I want to do is crawl my contacts in a social network and extract the Twitter URLs from their profile pages. My current plan is to open each profile in it's own tab, so that it looks more like a normal browsing person (ie css, scrits and images will be loaded by the browser). Then store the Twitter URL with GM_setValue. Once all profile pages have been crawled, create a page using the stored values. I am not so happy with the storage option, though. Maybe there is a better way? I have considered inserting the user profiles into the current page so that I could all process them with the same script instance, but I am not sure if XMLHttpRequest looks indistignuishable from normal user initiated requests.

• Visual Studio 2008 Unresponsive When Opening JavaScript Files

  - by lush

  I'm starting a new ASP.NET project that I'm trying to use some jQuery with, but whenever I try to open .js file (blank or containing a few lines of javascript) in Visual Studio, it often hangs; showing the .js filename in a new tab, but the actual text editor window showing whatever was drawn to the screen before opening the .js file. Eventually, after closing and re-opening, it will open in the text editor, but the font is always something like 10pt Arial. Even after changing this in VS options, the next re-launch of Visual Studio yields the same results. Has anyone else experienced hang, unresponsiveness, wonkiness from Visual Studio with JavaScript files?

• Making Eclipse behave like Visual Studio

  - by FlySwat

  I'm doing some Android dev, and I much prefer Visual Studio, but I'll have to use Eclipse for this. Has anyone made a tool that switches Eclipse to look and behave more like visual studio? I mainly can't stand its clippyesqe suggestions on how I should program (Yes, I know I have not yet used that private field! Thanks Eclipse!), or its incredibly lousy intellisense. For example, in eclipse, if I don't type "this" first, its intellisense won't realize I want to look for locally scoped members. Also, the TAB to complete VS convention is drilled into my head, and Eclipse is ENTER to complete, I could switch everything by hand but that would take hours, and I was hoping someone had some sort of theme or something that has already done it :)
