• Changing tab indicators to a view in a tab widget?

  - by user246114

  Hi, I have a layout which requires a tab widget containing two tabs. Ideally I'd like to have each tab just be a completely flat colored rectangle, side by side. Almost exactly like the buttons you see at the top of this web page titled: "Questions" | "Tags" | "Users" | "Badges" | "Unanswered" but without the whitespace in between. I'd like to have the highlighted tab have a brighter background color. Is this possible using the tab widget? I know in 1.6+ there's a method to specify a view for the tabs themselves, but can I achieve this tight look, or should I just roll my own? Thanks

• Capture IP packets on Dialup connection - Windows 7

  - by Assaf Levy

  Our product utilizes (the wonderful) Winpcap to capture ip packets from all devices with an IP address and analyze them in real time. Unfortunately, we discovered that it does NOT capture any packets on dialup (e.g. PPP) connections on Windows 7, and that there are no near-term plans for enabling this (1). So we need something else. Microsoft Network Monitor and Windows Packet Filter are two options that surfaced during a bit of googling, but before delving into research I wanted to ask the experienced: what are out options, given the following requirements: Capture all in/outbound IP packets on the machine. Complete background processing - no UI should be involved. Support Windows Vista / 7. Performance (user should not feel the difference). Thanks in advance.

• Looking to redo a static website

  - by moorecats

  I have been asked to help redo my non-profit website. I would like to make it look better. What would be the best way to do this? I have some technical background and can learn. I have looked at various options such as Joomla, word press and so on but I am not certain on how to create a good UI for it. I have also looked at Ruby and such, which I think may be overkill for a static page such as this. I haven't done any programming etc in a few years, but I figure this may be an opportunity to get back into it.

• Is it possible to dynamically change the style/template of a control?

  - by elggarc

  I am creating a UserControl in Silverlight 4 which has a watermarked background. The watermark should change depending on the underlying 'type' the UserControl is representing. The watermark is created using a Path and I have extracted all the properties into a style. I was wondering if it would be possible to change the style of the Path at runtime based on some known value. I am using MVVM and Unity. Perhaps I could bind the style somehow? Or could I inject the style when the view is created? I may have to do this with control templates, hence the reference in the title. Thanks...

• Icon fonts vs images

  - by Miss A

  My manager tells me not to use icon fonts on our websites, as it is another http request plus the extra kBs to download. Also because I would have to use content before for the font (I can't change the html), he prefers background images so it works in IE7. Personally I love the little things, so nice and crisp and resizeable! I get it if we only use a couple of icons on a website but if I would use, say 5 icons on a site - what do you guys think? Is it worth using an icon font or is he right thinking that it is not? I am just a sucker for anything new and exciting, and this year it is the retina display.

• Database table schema design - varchar(n). Suitable choice of N

  - by morpheous

  Coming from a C background, I may be getting too anal about this and worrying unnecessarily about bits and bytes here. Still, I cant help thinking how the data is actually stored and that if I choose an N which is easily factorizable into a power of 2, the database will be more effecient in how it packs data etc. Using this "logic", I have a string field in a table which is a variable length up to 21 chars. I am tempted to use 32 instead of 21, for the reason given above - however now I am thinking that I am wasting disk space because there will be space allocated for 11 extra chars that are guaranteed to be never used. Since I envisage storing several tens of thousands of rows a day, it all adds up. Question: Mindful of all of the above, Should I declare varchar(21) or varchar(32) and why?

• How to create a MySQL query for time based elements with a 'safe window'?

  - by pj4533

  I am no SQL expert, far from it. I am writing a Rails application, and I am new at that as well. I come from a desktop programming background. My application has a table of data, one of the columns is the time at which the data was logged. I want to create a query with a 'safe window' around EACH row. By that I mean, it returns the first row, then for X minutes (based on the timelogged column) it won't return any data, once X minutes is up, it will return the next row. For example: ID | TimeLogged 1 | 3/5/2010 12:01:01 2 | 3/5/2010 12:01:50 3 | 3/5/2010 12:02:03 4 | 3/5/2010 12:10:30 5 | 3/5/2010 01:30:03 6 | 3/5/2010 01:31:05 With a 'safe window' of 5 minutes I want to create a query to return: 1 | 3/5/2010 12:01:01 4 | 3/5/2010 12:10:30 5 | 3/5/2010 01:30:03 (It skipped the 12:01:50 and 12:02:03 items because they occurred within 5 minutes of the first item.) Another example, with a 'safe window' of 15 minutes I want to return: 1 | 3/5/2010 12:01:01 5 | 3/5/2010 01:30:03 Perhaps I have to just return all data and parse it myself?

• Sharepoint 2010 - Managed KeyWords

  - by Audioillity

  Hi, Is it possible to import managed keywords into SharePoint 2010? Where are the keywords stored within which database? Background - I'm currently working on a migration from a legacy system into SharePoint 2010. So far everything is going well, and I can even bring across the managed meta data across along with most other data. The process I use was built for SharePoint 2007 to update Lists over SOAP. With a few manual tweaks I've managed to get the metadata to come across. To bring across either managed metadata or managed keywords I need to know the ID for the existing label/keyword. I have this for the Managed Metadata however not for the Managed Keyword. Currently I create a CSV file to be imported for managed metadata before working out the reverent GUID for the source label. Many Thanks Luke

• Creating an OpenGL texture with alpha using NSBitmapImageRep

  - by BROK3N S0UL

  I am loading a PNG using: theImage = [NSBitmapImageRep imageRepWithContentsOfFile:imagePath]; from which I can successfully create a gl texture and render correctly without any transparency. However, when I switch blending on using: glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE); The texture renders with the correct transparent background, but the image colours are incorrect. I have tried several options in the blend function, GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE, GL_DST_ALPHA, etc. I was taught maybe I need to reorder the bits in the image data, maybe the channels have been mixed up, but I would not expect it to render correctly when blending is off in that case. Alternatively, I could use libPNG I guess, but I would like to try using a NSBitmapImageRep if it is possible.

• int i vs int index etc. Which one is better?

  - by Earlz

  Coming from a C background I've always used int i for generic loop variables. Of course in big nested loops or other complex things I may use a descriptive name but which one had you rather see? int i; for(i=0;i<Controls.Count;i++){ DoStuff(Controls[i]); } or int index; for(index=0;index<Controls.Count;index++){ DoStuff(Controls[index]); } In the current project I am working on there are both of these styles and index being replaced by ndx. Which one is better? Is the i variable too generic? Also what about the other C style names? i, j, k Should all of these be replaced by actual descriptive variables?

• CSS+HTML: tds are overlapping

  - by Budda

  On my web-site http://vfm-elita.com (it is not in English, sorry for that) - center and right columns are overlapping, please see screenshot for details: Between left and center columns you can see a "gap" with a green background - it is expected and good. But there are no any gap between center and right columns, instead they are overlapping. Issue exists in all known browsers There are no special formatting applied to columns. They are usual 'TD' columns, the only CSS modifier is width that is "250px" for left and right columns, and for center - it is "auto". Please advise how can I correct that error. Thanks a lot!

• Most efficient method of generating PNG as HTTP response

  - by awj

  I've built an ASP.NET page whose output stream is a dynamically-generated PNG image containing only text on a transparent background. The text is based upon database IDs contained in the querystring. There will be a limited number of variations. Which one of the following would be the most efficient means of returning the image to the client? Store each variation upon the first generation, and thenceforth retrieve this from the drive. Simply generate the image each time. Cache the output response based upon the querystring.

• Centering An Inline-Block DIV

  - by Aaron Brewer

  Does anybody know how to center align a DIV that has the display set to inline-block? I cannot set the display to block because I have a background image that needs to be repeated, and it needs to expand based on the content. It sits inside of a parent div, in which is larger when it comes to width. So all in all. Does anyone have a fix to center align a div with the display set to inline-block? And no, text-align: center; does not work, nor does margin: 0 auto; jsFiddle: http://jsfiddle.net/HkvzM/ Thank you!

• Android: how to convert whole ImageView to Bitmap?

  - by yosh

  I have my application that is displaying images with different ratio, resized inside (centerInside) imageView. What I need is to create bitmap from the ImageView including the background (black in this case). So for example I have device screen 320x480, full screen imageView with image resized to 280x480. How could I get 320x480 bitmap from it? On top of this imageview I have some logos or buttons that I don't want to include to bitmap, they're like on top layer. All I need is bitmap with image and black border from some sides.

• How does a youtube embed suppress the buffering of a video file?

  - by usingtechnology

  When a youtube video is displayed within an external site, a poster image is displayed but the actual video is not loaded until the user clicks the play button. At that point, the video file begins to buffer and the video plays. This seems to be different than many sites, where a flash video is embedded and the video begins to buffer automatically in the background on page load, regardless of whether the video is set to autoplay or not. How would you set up a flash video (non-youtube) to have the same behavior as youtube, where buffering does not occur at pageload? Is it an output setting that is selected during the flash video rendering process, or is it accomplished using a different method?

• Android: how to start a service at boot based on user-settings?

  - by Cicerone Cojocaru

  Hey everyone, I'm trying to write an app that consists of an activity that manages a background service. However, I want to implement a user setting for automatically starting the service up at boot time. I have user settings implemented with SharedPreferences and I have the services starting up at boot by using a BroadcastReceiver and listening for BOOT_COMPLETED. However, I can't figure out a good way to implement a setting so that the service is only started at boot if said setting is enabled. I can think of a few cheap ways to do this (such as messing with onCreate() in the service, or creating/checking for a file on SD card) but I want to follow good practice. There must be a good way to do this because there's tons of apps out there that do it, I just can't find anything online about how to do it. Thanks

• In C# is there a thread scheduler for long running threads?

  - by LogicMagic

  Hi, Our scenario is a network scanner. It connects to a set of hosts and scans them in parallel for a while using low priority background threads. I want to be able to schedule lots of work but only have any given say ten or whatever number of hosts scanned in parallel. Even if I create my own threads, the many callbacks and other asynchronous goodness uses the ThreadPool and I end up running out of resources. I should look at MonoTorrent... If I use THE ThreadPool, can I limit my application to some number that will leave enough for the rest of the application to Run smoothly? Is there a threadpool that I can initialize to n long lived threads?

Outloock WP7 included in the operating system then updates the icon so that you can see that there are new mail. This is a process in the background running. But I've read a bit about this now, but can not find out that this is possible using the SDK from Microsoft? Is it not possible?? If possible, how does one do that? Notice: I do not want any solution that involves jailbreak.

• The glutKeyboardFunc does not react to key presses immediately

  - by Nibirue

  I have a function glutKeyboardFunc(keyboard), where keyboard has: void keyboard(unsigned char key, int x, int y){ float alpha = 1.0; switch(key){ case 'c': glClearColor(1,0,0,alpha); printf("success"); break; } } This is a summary of the function; it works properly, but only once some other action has occurred. For instance, the printf statement reports success immediately on keystroke 'c', but the background color does not become active until I click somewhere else on the canvas. I want all keystrokes to have an immediate effect.
