• How to create an GUI that communicate with the USB Devices

  - by VINAYAK

  I am doing my Project using win 32 programming.I am just learning about win32 programming and able to create an UI.I want to communicate with an USB Device with that UI.SO,How can i go for that?Is there any predefined functions will be there are we need to create the function for communicating with the OS and get the devices List and got the details about them. My purpose is to , 1.Creating an UI that tells about the Basic information about the device(We want to send a control request to the device to get the descriptors). 2.For that first of all i want to communicate with the OS for device attachment.That will lead to get the information about the device and Enumeration takes place and then only i request the device information through descriptors by using standard Requests. 3.And also i want to create the driver for my device.That will also need to achieve for communicating with OS(Windows). So,can anyone help me about this?How can i achieve this or approach this? Note: I am at the entry level now so anyone give response will be in a detailed format like step by step process would be appreciable.

• mount ext4 formated external drive->the drives green light won't stop flashing

  - by Gohlool

  I've installed kubuntu (after 10 years I am trying to play with linux) and manged to attach a external 1TB HDD drive over USB! The drive was formatted with NTFS and everything was working OK. I also changed the /etc/fstab here is my ntfs mount setting: /dev/sdb1 /media/samsung nts-3g auto,user,uid=1000,gid=1000,fmask=000,utf-8 0, 0 Now, I've reparationed the drive and formated it with ext4 filesystem! change my fstb like: /dev/sdb1 /media/samsung ext4 defaults,noatime 0, 0 now, when I plug my dive/or call sudo mount -a, my external drive's green light starts to flash and won't stop, but mount works .... What is the Problem? is this because of ext4? because with NTFS this won't happen! btw. after changing the owner of the /media/samsung and setting permissions 777, I can also access my drive like creating new folder atc. (although is's flashing constantly)! What is my mistake? btw. can you please let me know how to set the owner and the permissions for my /media/samsung directory in fstab for ext4 like I did it for NTFS? Thanks in advance

• Operating System not Found after installing Ubuntu in a Sony Vaio

  - by diego8arock

  I just bought a Sony Vaio SVS15115FLB that came with Windows 7, after enjoying the PC graphic power for a little, I decided it was time to install Ubuntu 12.04. First, I inserted a USB stick, reboot, press F11 but a message saying that no OS was found on the USB, so then I used a live CD. It booted fine and I installed Ubuntu, then when it was time to restart the PC, it didn't boot to GRUB but it went straight to Windows and it began an startup error and was looking for a solution, after it was done, it restarted and then it booted again to Windows and to the same start up error solution thing. I freaked out, so I booted again the Ubuntu live CD, and installed Ubuntu over everything, after it installed I rebooted and then a message appeared saying Operating system Not Found, and I have no idea why. So I Googled again and found this post on Boot Partition, I did everything exactly on that post, but it didn't work (by the way, this was the message): The boot files of [Ubuntu 12.04 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. It appeared the first time, then I did it all again and then it was gone. I rebooted and nothing, the same Operating System not found message appeared. So I decided to create a partition for Windows, hoping for something, but the message still appears. I really have no idea what to do, but there is something odd, if I insert the USB stick containing Ubuntu 11.10, the message that says that there is no OS in the PendDrive flashes for a fraction of a second and the boot straight to Ubuntu 12.04 without problems (and booted to Windows when I installed it, ignoring Ubuntu), right now I'm using it like that, but its pretty annoying. Can anyone advise me how to fix this? I'm no expert on this kind of things (boot, GRUB, recovery and stuff like that).

• Why does my player stop when stepping onto a new tile?

  - by user220631

  Me and my friend are creating a game from scratch. He is in charge of art design and I am in charge of coding. I have done well so far with the code, but I have a collision detection problem when the character moves right: Once the player moves right, whenever a new block is encountered, the player stops. I don't know if this is a problem with collision or the player but I can't work around it. Here is the collision code: this.IsColliding = function(obj) { if(this.X > obj.X + obj.Width) return false; else if(this.X + this.Width < obj.X) return false; else if(this.Y > obj.Y + obj.Height) return false; else if(this.Y + this.Height < obj.Y) return false; else return true; } I also wanted to see if there as a way to make the player collide with the bottom of the block and the right side of the block instead of running through it.

• Need advice on framework design: how to make extending easy

  - by beginner_

  I'm creating a framework/library for a rather specific use-case (data type). It uses diverse spring components, including spring-data. The library has a set of entity classes properly set up and according service and dao layers. The main work or main benefit of the framework lies in the dao and service layer. Developers using the framework should be able to extend my entity classes to add additional fields they require. Therefore I made dao and service layer generic so it can be used by such extended entity classes. I now face an issue in the IO part of the framework. It must be able to import the according "special data type" into the database. In this part I need to create a new entity instance and hence need the actual class used. My current solution is to configure in spring a bean of the actual class used. The problem with this is that an application using the framework could only use 1 implementation of the entity (the original one from me or exactly 1 subclass but not 2 different classes of the same hierarchy. I'm looking for suggestions / desgins for solving this issue. Any ideas?

• Can i create a virtual machine on my laptop to be used with another monitor?

  - by Ranhiru

  OK, the scenario is like this... I have my laptop... and I have another user without a unit. He has only a keyboard, mouse and a monitor. Is there anyway that I can make him use my computer by creating a virtual environment which he will access, BUT, without interfering with my work. I use my laptop and view my OS from the laptop monitor. I create a virtual environment (some OS probably XP) and run it. The virtual environment is displayed in the connected monitor and the other user uses it using the extra keyboard/mouse and the monitor but without interfering my screen! Is this possible? Stupid? Futuristic? Need more hardware?

• How successful is GPL in reaching its goals?

  - by StasM

  There are, broadly, two types of FOSS licenses when it relates to commercial usage of the code - let's say the GPL-type and the BSD-type. The first is, broadly, restrictive about commercial usage (by usage I also mean modification and redistribution, as well as creating derived works, etc.) of the code under the license, and the second is much more permissive. As I understand, the idea behind GPL-type licenses is to encourage people to abandon the proprietary software model and instead convert to the FOSS code, and the license is the instrument to entice them to do so - i.e. "you can use this nice software, but only if you agree to come to our camp and play by our rules". What I want to ask is - was this strategy successful so far? I.e. are there any major achievements in the form of some big project going from closed to open because of GPL or some software being developed in the open only because GPL made it so? How big is the impact of this strategy - compared, say, to the world where everybody would have BSD-type licenses or release all open-source code under public domain? Note that I am not asking if FOSS model is successful - this is beyond question. What I am asking is if the specific way of enticing people to convert from proprietary to FOSS used by GPL-type and not used by BSD-type licenses was successful. I also don't ask about the merits of GPL itself as the license - just about the fact of its effectiveness.

• remote symbolic link / junction

  - by Blueberry

  Might be a pretty obvious one but have had some trouble finding solid answers. I have a directory on a windows network share containing different versions of an application. I would like to have a link to one of these called 'current', which will be a symbolic link to the directory sitting beside all the other versions and pointing to one of these. Creating this link seems to be more of an issue than I would have thought. Looks like symlink only shows the link on the same machine as where it was created (which is not going to work for obvious reasons) and junction needs to be run on the server which is practically impossible due to various restrictions. What would be the best way to go about this? Would I just need to copy the files twice or can I have a symbolic link which can be created and accessed remotely?

• How to script Win7 start menu customizations using powershell

  - by mandrake

  I'm creating an unattended installation of Windows 7 and like to customize the start menu programmatically. The goal is a minimalistic start menu with only "All applications" and perhaps a pinned program link. Is this scriptable using powershell (or perhaps wsh)? And is it possible to change this on the default user template so that new users inherit these changes? Code samples or documentation regarding this would be nice. Summary of changes I'd like to make: Change privacy settings "store recently opened programs" (and items) Don't display... Control panel. Connect to. Etc Pin program to start menu

• Turning a problem into a data

  - by Fogmeister

  OK, I have an app that I'm creating but I'm just really not sure about how to approach the problem. The idea is fairly simple. I'm just not sure how to wrap it in a data model (or even if I should). TBH I feel like I'm making it more complicated than it needs to be. How it works. The app will have circles along the top in a row that need to be connected to circles along the bottom in a row. 10 circles at the top. 10 at the bottom. One connection per pair of dots. Anyway, I can get the dots to connect I'm just not sure how to wrap it in a data model so that I can analyse what has been connected and see if it is right or not. The circles will be questions and answers. I can make an array of question objects with a question and answer properties. I can then display these as the dot pairs. I'm just not sure how to record which questions have been connected to which answers. It is valid for a user to connect a wrong answer as they all get checked at the end. I was thinking of using SpriteKit but this isn't a restriction. I could use UIKit or something else. TBH, this question is fairly language free as I'm just after a way of modelling it.

• Collision detection with non-rectangular images

  - by Adam Smith

  I'm creating a game and I need to detect collisions between a character and some parts of the environment. Since my character's frames are taken from a sprite sheet with a transparent background, I'm wondering how I should go about detecting collisions between a wall and my character only if the colliding parts are non-transparent in both images. I thought about checking only if part of the rectangle the character is in touches the rectangle a tile is in and comparing the alpha channels, but then I have another choice to make... Either I test every single pixel against every single pixel in the other image and if one is true, I detect a collision. That would be terribly ineficient. The other option would be to keep a x,y position of the leftmost, rightmost, etc. non-transparent pixel of each image and compare those instead. The problem with this one might be that, for instance, the character's hand could be above a tile (so it would be in a transparent zone of the tile) but a pixel that is not the rightmost could touch part of the tile without being detected. Another problem would be that in different frames, the rightmost, leftmost, etc. pixels might not be at the same position. Should I not bother with that and just check the collisions on the rectangles? It would be simpler, but I'm afraid people.will feel that there are collisions sometimes that shouldn't happen.

• How to Deal with an out of touch "Project manager"

  - by Joe

  This "manager" is 70+ yrs old and a math genius. We were tasked with creating a web application. He loves SQL and stored procedures. He first created this in MS access. For the web app I had to take his DB migrate to SQL server. His first thought was to have a master stored procedure with a WAITFOR Handling requests from users. I eventually talked him out of that and use asp.net mvc. Then eventually use the asp.net membership. Now the web app is a mostly handles requests from the pages that is passed to stored procedures. It is all stored procedure driven. The business logic as well. Now we are having an one open DB connection per user logged in plus 1. I use linq to sql to check 2 tables and return the values thats it period. So 25 users is a load. He complains why my code is bad cause his test driver stored procedure simulates over 100 users with no issue. What are the best arguments for not having the business logic not all in stored procedures?? How should I deal with this?? I am giving an abbreviated story of course. He is a genius part owner of the company all the other owners trust him because he is a genius. and quoting -"He gets things done. old school".

• See network computer description in Explorer

  - by John Gardeniers

  When viewing the list of network computers in Windows Explorer on a Win 7 machine there appears to be no way of readily seeing the description field, which makes that pretty well useless. I believe this problem started with Vista but I'm seeing it for the first time because I was fortunate enough to skip over Vista. We're currently rolling out Win 7 on new boxes and although I'm changing the naming system to something more sensible, the old boxes have names such as FWS01, FWS02, etc. Managing a network of computers with such names is made more difficult when you can't readily see who's machine each one is. Googling the problem brought up a workaround involving creating a shortcut on an XP machine and copying that to the Win 7 box but that's a long way from ideal. Is there some kind of hack that can be applied to machines, the operator of which needs to be able to see the description field?

• How can I get cross-browser consistent behavior for TR heights within a table with a set height? [migrated]

  - by Dan

  I have an arbitrary number of tables with an arbitrary number of rows in each, and all tables are the same height. My initial approach was to just set the overall height of the table and hope the rows were smart enough to distribute themselves appropriately. That's not the case. I have 4 different behaviors going on with 4 browsers, but I need them to all render at the very least in a similar way. Safari & Chrome (WebKit): All rows are equal height, creating scroll bars as needed and fitting within table height. Firefox: All rows are the height necessary to fit their content, with the remaining rows overflowing out of the table. Additionally, If the content of the rows does not take up all of the height, only the part of the table with content in it takes the background (though it seems, through use of Firebug, that the actual table [and TR] extend to the bottom of the proper table height). IE: All rows are the height necessary to fit their content, with the remaining rows overflowing out of the table. Obviously this only includes one version of each browser and additional variation would likely appear with more being tested. Ideally, a solution where the browser renders TRs with less content smaller than those with larger content, while still using scrolling within the variable height TRs when the overall height of the table is not enough would be optimum. I could potentially see a solution to achieve that with JS, but can it be done with CSS? Or, if not, can the behavior that WebKit displays be made to work across the browsers? Thanks! PS: Example can be found here.

• Best Guest OS for running freeswitch under Proxmox

  - by Frank Waller

  We have a lot of asterisk Systems running on dedicated machines and would like to use freeswitch to replace a number of them. One of the advantages of freeswitch is supposed to be that it is doing much better in a virtualized environment than asterisk is. However I can find very little information about people using it in Proxmox containers. I would like to know if anyone has seen any ready to run proxmox images that include freeswitch so we can test a number of things without having to deeply go into creating our own. Or at least a clue to which system images/distro images we can use to quickly get it installed not having to deal with too many dependency or different Linux version issues. Just to be clear: It should be for a more or less current Proxmox and current freeswitch. I am not looking forward to use the KVM mode but would consider it, if it is otherwise ready to run out of the box. I would rather use a real OpenVZ based container. Thanks for anyone helping!

• Preventing ugly hyperlinks in Word-generated PDFs?

  - by Jay Levitt

  I'm creating a document in Word 2007 on Windows XP, and using the "Save As PDF" add-in. The document contains hyperlinks. When I open that PDF in Preview.app on a Mac (OS X 10.5.8), I see ugly boxes around all the hyperlinks. I've tried editing the PDF in Acrobat Pro 9.2.0 on the Mac, but the boxes don't show up there. If I select a hyperlink anyway with the Link Tool, right-click, and select "Properties..." no properties dialog ever appears. I want the links to be clickable, but I want them to look decent. How can I fix them? I don't have Acrobat for Windows.

• Displaying a Grid of Data in ASP.NET MVC

  One of the most common tasks we face as a web developers is displaying data in a grid. In its simplest incarnation, a grid merely displays information about a set of records - the orders placed by a particular customer, perhaps; however, most grids offer features like sorting, paging, and filtering to present the data in a more useful and readable manner. In ASP.NET WebForms the GridView control offers a quick and easy way to display a set of records in a grid, and offers features like sorting, paging, editing, and deleting with just a little extra work. On page load, the GridView automatically renders as an HTML <table> element, freeing you from having to write any markup and letting you focus instead on retrieving and binding the data to display to the GridView. In an ASP.NET MVC application, however, developers are on the hook for generating the markup rendered by each view. This task can be a bit daunting for developers new to ASP.NET MVC, especially those who have a background in WebForms. This is the first in a series of articles that explore how to display grids in an ASP.NET MVC application. This installment starts with a walk through of creating the ASP.NET MVC application and data access code used throughout this series. Next, it shows how to display a set of records in a simple grid. Future installments examine how to create richer grids that include sorting, paging, filtering, and client-side enhancements. We'll also look at pre-built grid solutions, like the Grid component in the MvcContrib project and JavaScript-based grids like jqGrid. But first things first - let's create an ASP.NET MVC application and see how to display database records in a web page. Read on to learn more! Read More >

• Hibernation to a swap file 12.04, fragfile output

  - by MrHug10

  I've been trying for some time now, to get hibernation working in Ubuntu 12.04 on my Dell XPS17. I dualboot Windows 7 and Ubuntu, each having their own partition and one shared partition for all my data and documents. As I would like to be able to swtich from ubuntu to windows without losing all the things I was currently doing in Ubuntu, I would like to be able to use hibernation. In order to achieve this I've followed the information at http://ubuntuforums.org/showthread.php?t=1042946. Only instead of creating my swap file on my linux partition (which is formatted: ext4), I've chosen to create one on my shared partition (which is formatted: ntfs). There is a problem with this though (at least, that's what I think the problem is), because when I call: sudo filefrag -v /media/data/Ubuntu_Swap_Space/6GiB.swap, I get the following output: Filesystem type is: 65735546 File size of /media/Data/Ubuntu_Swap_Space/6GiB.swap is 6442450944 (1572864 blocks, blocksize 4096) Discontinuity: Block 22 is at 25829097 (was 232498) /media/Data/Ubuntu_Swap_Space/6GiB.swap: 2 extents found So I'm not sure what I need to fill in as an offset to follow the rest of the earlier mentioned information. I've tried both the location of block 22 and the number that is listed after that, but when I then try sudo pm-hibernate nothing happens and this shows up in my /var/log/pm-suspend.log s2disk: Could not use the resume device (try swapon -a). Reason: No such device Hope someone can help me out with this! If you need more information about anything, please let me know!

Server characterset: latin1 Db characterset: utf8 Client characterset: latin1 Conn. characterset: latin1 ... Using the following command: mysql> show create table text; I see that the table create statement set the charset to binary: CREATE TABLE `text` ( `old_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `old_text` mediumblob NOT NULL, `old_flags` tinyblob NOT NULL, PRIMARY KEY (`old_id`) ) ENGINE=InnoDB AUTO_INCREMENT=317 DEFAULT CHARSET=binary MAX_ROWS=10000000 AVG_ROW_LENGTH=10240 How should I use mysqldump to properly generate a backup for that database?

• Setting up Clojure Project And Sub Projects

  - by octopusgrabbus

  This is primarily a lein question about setting up a major project and its sub-projects, and is not intended to be a discussion question. Instead, I am interested in either a pointer to documentation or to a Clojure/lein best practices link. I have a municipal property assessments application that splits two master flies into different subset files, depending on whether a billing transfer is taking place or we want to batch update new accounts, rather than making our assessment department enter new accounts once in their system and then again in the tax collection system. My application is going to be large enough, that I can see a common library lein project with support functions, like splitting apart the files, and then individual lein projects that use the common library. Should the lein projects be set up at the same level and support included through the project.clj/core.clj files? Is there an advantage to creating lein new projects underneath a major project? Is there a problem with combing all functions in one project? I can probably make my one core.clj contain all flavors of the program, but coming from a C/C++ and Python background, I would prefer to have a lot of little projects.

• Easier way to create floppy disk images?

  - by Bryan

  I'm using Vyatta routers with KVM and want to attach a floppy drive with a config file for Vyatta when I boot the image. I'll be doing this over and over again, and as such am looking for an automated way of creating the floppy images. Right now, I'm doing the following: Create floppy image with qemu-img create Format floppy image with mkdosfs Mount floppy image with mount -t fat /tmp/floppy.img /media/floppy Populate floppy image with cp -r /tmp/configs/ /media/floppy/ Unmount floppy image with umount /media/floppy Save floppy image with mv /tmp/floppy.img ~/floppies/ Any chance there's an easier way to do this?! Perhaps a shortcut application that I can give a directory to and it will do all this for me w/out having to mount the image?

• BI Publisher : Formatting Issues

  - by Manoj Madhusoodanan

  While creating BI Publisher reports the formatting issues are quite common.Here I am discussing some common issues related to BIP report development. 1) First issue is related to column formatting.When you want to display some data which has leading zeros or trailing zeros after '.' in EXCEL output you will not get the desired output.But in PDF it will come as what you are expecting.This is not with the issue of your data. This is due to the unique nature of EXCEL cell format.When you are trying to put a text data in a cell with out making any change to cell format it will treat as number and it will truncate all leading zeros and all trailing zeros after '.' . So what you have to do is to convert that data into a format which EXCEL can treat as text. Eg: If you want to display 0020100 convert this data into ="0020100". Same way for 23789.02300 to ="23789.02300".   Note: This is applicable to EXCEL output only.If you have multiple output type apply it only for EXCEL. 2) Second is related to report size issue in PDF output type.If the number of columns are more and if you want to show most of the columns in one row andif it is a PDF output you can choose the paper size as Legal (8.5 x 14''). You will get more spaces in the template to accommodate more columns. 3) If your XML data contains special characters like &,<,> etc ..  pass the data to DBMS_XMLGEN.CONVERT function.It will replace special characters with corresponding XML notations. Eg: (a>b) & (c!=d) to  (a&gt;b) &amp; (c!=d)
