• Just when I thought my site was working right, it screws up in IE7

  - by John

  I thought I'd done quite well, my site passed XHTML1.0 strict validation and worked flawlessly in IE6 as well as looking fine in IE8 & Chrome. I glibly thought that it it worked in IE6 & 8, IE7 was bound to be OK. But on checking I see one of my has a scrollbar in IE7, the seems about 200% as wide as it should be... the content is fine but you can scroll the whole . 2 separate pages have this issue, a 3rd does not, even though all pages use the same layout template - the main difference on the 2 that break is a floated div. Are there known issues specifically in this area with IE7? Or do I have to embarrass myself by posting a link to the site?

• Drawing rectangles on a grid in a web browser

  - by Dhruv

  I would like to create an online, simple WYSIWYG drawing editor allowing people to draw rectangular shapes. I'm thinking of a grid which the lines and points can snap on to, ensuring that the lines are strictly vertical or horizontal. I will be parsing the rectangular shapes to obtain some area calculations and compute certain things. How can I achieve the drawing ability? The new canvas tag is good but people have been telling me that IE does not support it. I found some Java applets but I have never programmed in Java before. Is there a way to do this using pure javascript or jquery? Does ASP.NET help at all? Thanks.

• I can't get areas working in VS2010

  - by devlife

  I just upgraded from VS2010 RC to RTM. Now my areas aren't working. I have a Profile area with a Home controller and an Action method Index(). If I try: http://localhost:4951/profile I get a 404 error saying that the resource can't be found. If I try http://localhost:4951/profile/home I get the same error. However, if I try http://localhost:4951/profile/home/index then the view is returned. Here is my ProfileAreaRegistration: public class ProfileAreaRegistration : AreaRegistration { public override string AreaName { get { return "Profile"; } } public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Profile_Unlock", "Profile/Unlock/{userID}/{unlockID}", new { controller = "Unlock", action = "Index" }, new { userID = new GuidRouteConstraint(), unlockID = new GuidRouteConstraint() } ); context.MapRoute( "Profile_default", "Profile/{controller}/{action}/{id}", new { action = "Home", id = UrlParameter.Optional } ); } Does anyone know what is going wrong?

• Django - raw_id_fields title not refreshing.

  - by James Howell

  Hi, I am currently having an issue when using the raw_id_field within admin.py in my Django project. My site's admin area has a number of image upload fields for various different model pages which are all ForeignKey fields to an Image model where all images for the site are stored. As the site will eventually be dealing with a large quantity of images (100s, maybe 1000s) the default select box would be unusable. I created various admin.ModelAdmin classes e.g class InfoSlideAdmin(admin.ModelAdmin): raw_id_fields=('image',) These change the image selector within my Edit pages from a Select Box to a Raw ID Field. However when I select a different image using this control although the ID of the new image is shown the title from the previous image still displays. Any ideas?

• Getting search results from Twitter in php

  - by Mark Mayo

  I'm attempting to put together a little mashup with some twitter APIs. However, the whole area is new to me (I'm more of an embedded developer dabbling). And frustratingly, every tutorial I am trying in Php is either out of date, not doing what it claims to do, it or is broken. Essentially, I just want a nice bit of example code - say, an HTML file, a connection.js for the JQuery magic, and a php file - 'getsearch' which contains the relevant Curl calls to the API to just return the results for a given search term. Followed the tutorial to the letter at http://www.reynoldsftw.com/2009/02/using-jquery-php-ajax-with-the-twitter-api/ and even downloaded the guy's code and chucked it on my webserver, but it just seems to sit there. I'm relatively competent at php and html, but it's the Curl and the JQuery side of things which is new to me, and would appreciate any thoughts, links, or code suggestions. I've attempted reading the API - but even that seems sparse - and several links are broken to their own tutorials, so that's put me off a bit for now.

• wxPython ,Change the background colour of a StyledTextCtrl

  - by user1357159

  I tried (but nothing happens) self.txt.SetBackgroundColour ((255,0,0)) As said in the title I'm trying to change the background colour StyledTextCtrl. Does anyone know a method that could be used? I've checked the API docs but I couldn't seem to find one, http://wxpython.org/docs/api/wx.stc.StyledTextCtrl-class.html (by background colour, I mean the whole writing area, of course) Does anyone know a way I could do this? EDIT: The background doesn't change in the following code import wx import wx.stc app = wx.App(redirect=True) top = wx.Frame(None, title="StyledTXTCtrl", size=(300,200)) txt=wx.stc.StyledTextCtrl(top) txt.SetBackgroundColour((255,255,0)) txt.Refresh() top.Show() app.MainLoop()

• How do I create a WPF Dropdown panel

  - by Mitch

  I'd like to create a dropdown panel in WPF the acts like a ComboBox/Expander hybrid. I'm currently using an Expander but it pushes the the controls underneath it down when it expands. I simply want it to act like a ComboBox and overlay it's dropdown. I've looked at using Popups but they don't move with the underlying window if it's moved. So, I've concluded that the closest control to my needs is a ComboBox with allows me to put a Grid or StackPanel into its dropdown area. Any ideas how to achieve this?

• Is looking for Wi-Fi access points purely passive?

  - by Aric TenEyck

  Say I carry a Wi-Fi enabled phone or laptop through an area where there are WAPs. Assuming that I don't actively try to connect to them or otherwise interact with them, is it possible for the owner of that WAP to know that I was there? I'm asking this in the context of my earlier question: Looking for MACs on the network I was talking with a friend about my newfound ability to detect phones (and other devices with MAC addresses) on the network, and he pointed out that it might be useful to detect unknown phones on the network; I could use that data to track down anyone who was in my house and brought a Wi-Fi phone with them. So, if I set up a logging fake WAP with no security or encryption, can I glean any useful information about the devices that come into the house? Assuming that the thief doesn't actively try to connect...

• Differing form size between XP and 7

  - by Andy

  I am developing a C# WinForms app on my XP dev machine with Visual C# Express 2008. I set the form to have a size of my liking with Width and Height on the designer and all looks good. I also set these dimensions to the MaximumSize property. Deploying the app to another XP machine, and the app looks like it does on my dev. However, in testing the app on a Win7 machine, the form has both horizontal and vertical scrollbars applied. I assume that this is due to the changed non-client size of the form, as determined by Win7. I can resize the window, but I would like it to be displayed correctly to begin with. So, my question is: What is the best way to correctly maintain a form size client area across OS'es? Thanks all.

• EPOC EMOTIV cognitive suite is user dependent or independent

  - by Varun Malhotra

  After working a bit with EPOC EMOTIV, i suspect that its cognitive suite is user dependent, though its other suites are not and work absolutely well in all cases. It's use in cognitive area is wide and many such applications have also been developed. BCI CAD 3D geometry shapes are also a good example. But the main issue i want to highlight is that is it's cognitive suite depends on a particular set of data( same set always). I want to work more deeper with cognitive suite so any help(suggestions, research papers, EEG data processing), anything which can be a great source to deal with. Thanks!

• plot only x and y axis (no box) in ggplot2

  - by Tyler Rinker

  The convention of some journals is to show only the x and y axis in a plot not a box around the entire plot area. How can I achieve this in ggplot2? I tried theme_minimal_cb_L from HERE but it seems to erase the entire box around the plot (does not leave the x and y axis) as seen here: Here's the code I'm using: dat <- structure(list(x = c(0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3), y1 = c(34, 30, 26, 23, 21, 19, 17, 16, 15, 13, 12, 12, 11), y2 = c(45, 39, 34, 31, 28, 25, 23, 21, 19, 17, 16, 15, 14)), .Names = c("x", "y1", "y2"), row.names = c(NA, -13L), class = "data.frame") library(reshape2); library(ggplot2) dat2 <- melt(dat, id='x') theme_minimal_cb_L <- function (base_size = 12, base_family = "", ...){ modifyList (theme_minimal (base_size = base_size, base_family = base_family), list (axis.line = element_line (colour = "black"))) } ggplot(data=dat2, aes(x=x, y=value, color=variable)) + geom_point(size=3) + geom_line(size=.5) + theme_minimal_cb_L()

• Which source control to use (for a lot of images file)?

  - by invisal

  I finally decide to give a source control a try with my existed project (since I will be hiring another new developer soon). I am pretty new to this area and I need recommendation which Source Control should I use to fix my current project. I am developing Web Application which dealing with large number of pictures. Currently, we have over 500,000 pictures (large size picture and several thumbnails). I am using PHP which is not what I concern (since it is just only hundred of script files). My major concern is with the large amount of picture. NOTE: I just install VisualSVN. What do you think about SVN. Do you think it will fix to my requirement?

• HTML5 Canvas compositing question (source-in)

  - by Alex Ciarlillo

  I am trying to recreate a page flipping type animation in HTML5 using canvas. The animation is based on ideas from here: hxxp://oreilly.com/javascript/archive/flashhacks.html but thats not really important. The problem I am having is that using the 'source-in' composite operation is not giving me the results I expect and would like clarification as to why. Here is the example: (i think it can only be viewed in chrome, not working in FF 3.6) http://acpound.fylez.com/test/example.html The black rectangle is supposed to act as a 'mask' for the page being turned over. All I want to see is the turning page in the areas where it overlaps the mask. The problem is the entire black rectangle is drawn, not just the area where they overlap. The source is all on the page. I know HTML5 isn't really being used yet, I'm just experimenting for my personal site and curiosity. Any ideas would be greatly appreciated.

When on the first dialog I click "left" button - controls on the second dialog must move to the left. But unfortunately I don't know Win32 API at all. How can I implement it? What kind of Win32 API mechanism should I be using? Thanks.

• Manage dirty rect efficiently

  - by Tianzhou Chen

  Hi all, I am implementing a view system and I want to keep track of all the dirty rects. It seems my dirty rect management is a bottleneck for the whole system. On one hand, invalidating the bounding box of the dirty region seems to be an easy approach. But in the situation like this: Say I have a client area of 100x100; I have a dirty rect with (0, 0, 1, 1) and another dirty rect with (99, 99, 1, 1). Invalidating the bounding box which turns out to be 100x100 is not efficient at all. So I want to ask if someone can give any hint or give me a link of the related literatures. Thanks in advance!

• Best way to track impressions/clicks in a bespoke advertisement system?

  - by Martin Bean

  I've been asked to create a bespoke advertisement system despite suggesting open source alternatives such as OpenX and DoubleClick for Publishers (the former Google Ad Manager). I've got the basics of the system set up, i.e. uploading creatives, creating positions and a mechanism to place creatives within positions; however, the area I'm stuck with is impression and click tracking. At the moment an impression and click is stored with the creative, but this then means impressions/clicks can't be queried. For example, we can't find how many impressions were in position x between date y and date z. How would I go about storing that kind of data? My theory was store the creative ID, position ID and timestamp in a database table, but given the amount of traffic the site has this would produce a very large database very quickly. If any one could give me a pointer or two, that would be great.

• Whats the best way to deal with backups for my php/mysql application

  - by spirytus

  I'm creating php application for my client and now thinking what would be the best way to do backups, automatically if possible? I don't have much experience in this area and in case something goes wrong, or if I need to migrate, I would like to have fast way of getting it all back online. I understand "something goes wrong" is a very wide term, but lets say that someone hacks my site and wipes out database and all the files. My app. is written in php/mysql and I got access to cpanel (hosted with justhost.com if that makes any difference :). I used Joomla and it has JoomlaPack that does complete backup almost automatically and in case site fails, its easy to revert, or migrate if necessary. Is there anything like that for my configuration that would make reverting/migration, easy?

• Reset application and settings on user change

  - by Don

  Currently working on a project where a login will be required to use the application. I'm trying to figure out a smarter way to reset the application if someone is somehow logged out and the next one to login is not the same user. The option I have come up with at the moment is storing all user specific data/information in a DTO but this leaves me with cleaning up some parts of the work area. Is a ResetControls my only option here? I'm afraid that when updating the application someone might forget to update that part, most likely myself now that wrote it out. Anybody with experience in this that could provide some ideas to a simple yet fairly automagic solution?
