• Can I set a style for the content of an iframe from the main page?

  - by Joel Coehoorn

  We have a page the embeds a Google Calendar in an iframe. Recently, a warning box div began appearing on the calendar that looks like this: <div id="warningBox" style="color:#aa0000;">Events from one or more calendars could not be shown here because you do not have the permission to view them.</div> Obviously the best solution here is to find the private events and remove them, but so far the search for those events has proved fruitless. This calendar is an aggregate of several calendars, including a few we don't control (ie weather). We're still looking, but in the meantime, I would like to try to hide that div. I know that iframes enforce the separation between the pages, such that the child page is pretty much a law unto itself. But surely there must be some way to set a style on an element inside the frame?

• What technology should I use for a complex report?

  - by SeaDrive

  I have a task to generate reports from a Visual Studio C# application. This is a replacement (caused by new requirements) for a program written using the built-in implementation of Crystal Reports. Although workable, it was far from ideal. The reports have conditional content (If type=1, print this, if type=2 print that.) Crystal does not adjust spacing dynamically and the various pieces were not the same length making for some unprofessional-looking spacing. I had thought of generating the reports in HTML, which would be feasible, but I'm concerned that you lose a degree of control, and I may be asked, e.g. to "move this up a bit" or similar which may be tricky. I'm not either a Crystal guru or an HTML guru. What other reporting technologies are available that would make it easy to drop in parts of different sizes, do table layouts, etc.?

• Drag and Drop ListBox for WPF

  - by drasto

  I'm looking for just a simple ListBox with build-in Drag & Drop. I think that Silverlite 4 Toolkit has something like that. The BoxList should be able to: reorder by draging & droping items drag item from one BoxList to another display preview (ghost version) of dragged item show drop location (like a line between items where the dragged will be inserted) I hope there is some solution from microsoft (in toolkit for example), but if not I all be happy with any working solution. For example I wander what control was used in DataGrid column headers reordering (by draging and droping them) implementation. Thank you for any suggestions

• asp.net mvc ignoreRoute with webservice

  - by boz

  Howdy, Im adding the filevistacontrol to my asp.net MVC web application. I have a media.aspx page that is ignored in the routing with routes.IgnoreRoute("media.aspx"); This works successfully and serves a standard webforms page. Upon adding the filevistacontrol, I can't seem to ignore any calls the control makes to it's webservice. Eg the following ignoreRoute still seems to get picked up by the MvcHandler. routes.IgnoreRoute("FileVistaControl/filevista.asmx/GetLanguageFile/"); The exception thrown is: 'The RouteData must contain an item named 'controller' with a non-empty string value' Thanks in advance.

• RMI client tracking

  - by 0000

  I'm building a Client / Server app that has some very specific needs. There are 2 kinds of servers: the first kind provide most of the remote procedures and clients connect to these directly, while the second kind is a single server that should keep track of what users are active (clients) and how many servers of the first kind are active when a method is called. The main thing is that the monitor should ONLY connect to the servers and not the clients directly. My first idea was to implement a simple login/logout rmi method when a client connects/ disconnects and keep track of those in a list but the main problem is when a client or server end abnormally. For example, if a client goes offline abruptly the server should somehow be notified and update the list accordingly, while if a server goes out all of the clients connected to it should be marked as not active in the control server. Any ideas of how to implement this functionality would be appreciated.

• How to determine ASP.NET's generated ID's from codebehind?

  - by Matthew Scharley

  In ASP.NET, when you give a tag an ID it generates a unique HTML id for the element based on the control hierachy, ie. <asp:Panel ID="test" runat="server"> ... </asp:Panel> <!-- Becomes... --> <div id="plc_lt_zoneContent_PagePlaceholder_PagePlaceholder_lt_test_test"> ... </div> Is there some way of determining the generated id in the codebehind file? I need to generate some Javascript that uses the id.

• How do you handle options that can't be used together with OptionParser?

  - by Joel

  My Python script (for todo lists) is started from the command line like this: todo [options] <command> [command-options] Some options can not be used together, for example todo add --pos=3 --end "Ask Stackoverflow" would specify both the third position and the end of the list. Likewise todo list --brief --informative would confuse my program about being brief or informative. Since I want to have quite a powerful option control, cases like these will be a bunch, and new ones will surely arise in the future. If a users passes a bad combination of options, I want to give an informative message, preferably along with the usage help provided by optparse. Currently I handle this with an if-else statement that I find really ugly and poor. My dream is to have something like this in my code: parser.set_not_allowed(combination=["--pos", "--end"], message="--pos and --end can not be used together") and the OptionParser would use this when parsing the options. Since this doesn't exist as far as I know, I ask the SO community: How do you handle this?

I can click the first cell in a row, but i cannot click the second... third... etc. Any suggestions?

• Why is checking in files called a 'commit'?

  - by Kjetil Klaussen

  The act of checking in files in a source control repository like git, mercurial or svn, is called a commit. Does anyone know the reason behind calling it a commit instead of just check in? English is not my mother tongue, so it might be some linguistic I don't quite get her, but what I'm I actually commiting to? (Hopefully I'm not commiting a crime, but you'll never know.) Is it in the meaning of "to consign for preservation"? Is it related to transactions (commit at the end of a transaction)?

• Pre-cache site as user visits

  - by strager

  I am making a static site which is 'forced' to be cached via Cache-control, etc. When a user visits my site, I want the browser to crawl my site, caching pages, so when the user navigates to a page, the load is almost instant. (I do not need a recursive crawl, as that will probably happen as the user navigates between pages. I just need to crawl the links on the current page, and of course not re-caching a page which has already been cached.) (Also, I am not changing pages using Ajax-like techniques. These are essentially normal flat HTML files with normal links.) How can I do this pre-caching using Javascript? (I am using jQuery.)

• Windows Server 2008 Antivirus Software with an API

  - by Dave Jellison

  I'm looking for an Antivirus package that is compliant with Windows Server 2008. That's not the hard part. What I need is an API layer on the Antivirus that i can call from managed .net code. For example: I am developing an Asp.Net (C#) website that allows users to upload files to the web server which the web site resides on. We have full control of the server so there are no security/rights issues on the server. I need to be able to run the antivirus algorithm on the newly uploaded files without (hopefully) shelling out to a command-ilne version of the software. Does anyone know of such a package?

• How to diagnose, and reverse (not prevent) Unicode mangling

  - by Steve Bennett

  Somewhere upstream of me, "something" happened that looks like unicode mangling. One symptom is that a lowercase u umlaut (ü) gets converted to "ü" (ie, character FC gets converted to C3 BC). Assuming that I have no control over this upstream process, how can I reverse-engineer what's going on? And if that is possible, can I crank the sausage machine backwards and get the original text back? (If it helps to understand this case, the text I received was in the form of a MySQL dump. I think somwewhere in the dump/transport process it got mangled.)

• Conditional value for ActiveRecord create method only

  - by Steve Wright

  I have a form where I have an administrator creating new users. The form uses the User model I created (login, password, first_name, etc...). For the last field on the form, I want to have a checkbox that doesn't need to be stored as part of the User record, but it is needed for the controller. This will control whether or not the newly created user will receive a welcome email or not. def create @user = User.new(params[:user]) if @user.save if @user.send_welcome_email UserMailer.welcome_email(@user).deliver end redirect_to(admin_users_url, :notice => "User #{@user.name} was successfully created.") else render :action => "new" end end In my view (haml) I am trying to access it like this: %p Send Welcome Email? = f.check_box :send_welcome_email I tried to make this an attr_accessible: :send_welcome_email but the controller does not recognize it. I get an undefined method 'send_welcome_email' for #&lt;User:0x00000100d080a8&gt; I would like it to look like this: What is the best way to get this working:

• Using View multiple times in Interface Builder

  - by user1396236

  I'm using a UITableview and have a custom Cell with some labels. I set up all the constraints in Interface Builder. Now I'm using this Cell multiple times, I just copied it in IB. Now it's the time to change some of these contraints because of some bugs (I'm converting a iPhone App to an Universal). But it can't be right that I now have to set the constraints manually for every cell? How do I do right? If I want to control the constraints in one central place, do I have to set them up in Code? I would really not like that! Thanks in advance.

• Different ways to specify libraries to gcc/g++

  - by abigagli

  I'd be curious to understand if there's any substantial difference in specifying libraries (both shared and static) to gcc/g++ in the two following ways (CC can be g++ or gcc) CC -o output_executable /path/to/my/libstatic.a /path/to/my/libshared.so source1.cpp source2.cpp ... sourceN.cpp vs CC -o output_executable -L/path/to/my/libs -lstatic -lshared source1.cpp source2.cpp ... sourceN.cpp I can only see a major difference being that passing directly the fully-specified library name would make for a greater control in choosing static or dynamic versions, but I suspect there's something else going on that can have side effects on how the executable is built or will behave at runtime, am I right?

• Cloud Apps and Single Sign-On (AD integration)

  - by Pablo Alvim

  I've been investigating some cloud vendors and the ability to implement single sign-on with them, especially when it comes to AD (Active Directory) integration. So far I've learned that with Azure this is possible through ADFS and the AppFabric Access Control offer. In AWS, since it is possible to create a VPN and see EC2 instances as a natural extension of a private datacenter, I believe implementing SSO would be rather simple (not sure if I'm right on this one... Please correct me if I'm wrong). With App Engine though, even though there is some documentation on AD synchronization (not full integration) for Google Apps, I'm struggling to find out whether AD integration would be possible... Is there any strategy for that? Any bit of information on cloud apps and AD integration will be appreciated!

• Object-oriented Programming - need your help

  - by wanderameise

  hey folks, I try to realize a little game project to dive deeper into OO programming (winforms c++/cli). I already started coding but now I´d like to make a re-design. For the beginning the game should consist of four parts like game-engine, user interface, highscore and playground. Heres a little (non-UML-conform) class diagramm to visualize my purposes http://i.imgur.com/lmpwj.png Would this be the right way? In my eyes the game engine is responsible to control the game sequences (state machine?) and exchanges information betweens all other classes. I appreciate any help!

• ReportViewer datadinding (WPF)

  - by user512150

  I have a rdlc file and I try to show it using report viewer control in WPF. My DataSource is called 'OfficeDataSet' and DataSet used in report is called 'Address'. I try to initialize report viewer (I put it in WindowsFormsHost) like this: private void PrepareReport() { reportDataSource = new ReportDataSource(); officeDataSet = new OfficeDataSet(); adapter = new AddressTableAdapter(); adapter.Fill(officeDataSet.Address); reportDataSource.Name = "OfficeDataSet_Address"; reportDataSource.Value = officeDataSet.Address; viewerInstance.LocalReport.DataSources.Add(reportDataSource); viewerInstance.LocalReport.ReportEmbeddedResource = "WpfApplication1.Reports.TestReport.rdlc"; viewerInstance.Location = new System.Drawing.Point(0, 0); viewerInstance.RefreshReport(); } but I got the message "A data source instance has not been supplied for the data source 'Address'". Anybody know what can be wrong with this code? (I'm totally new in WPF and Reporting Services).

• Mixing expressions and expression language (<%= %> inside of c:if)

  - by Jack

  I need to access some constants in my jsp, and sadly the EL does not offer any functionality for it. There are some options like the unstandard tag library, but I'd like to keep it a bit more standard. I tried: <%@ page import = "com.jackdane.Constants"%> <c:if test="${object.display == '<%=com.jackdane.Constants.YES %>}'"> //some display logic </c:if> But that doesn't appear to do the trick. It's been a while since I've used an expression so I might have made an error. Any input is appreciated. Edit: To clarify, the constants class is not in my control. It's inside a jar file that I recieved. It contains no getters/setters. Just private static final Strings.
