• Resumable Upload in Ruby on Rails

  - by user253011

  Hi, I have been searching for a way for resumable file upload in RoR. In conclusion, I found out other than Java Applet no client-side-and-cross-platform agent can access the file system in such a way that to request the file from the position where the upload got terminated (due to any reason) with some exceptions like http://github.com/taf2/resume-up/tree/master (built in native Ruby, but requires google gears which is not "reliable" yet when it comes to cross platform almost same story as of ActiveX!) Since the only reliable option left is java applet, is there any good tutorial/forum/documentation for those paid java applets, such as "thin slice upload" etc. to make it work with rails application. I have found one http : // github . com / dassi / mediaclue , its a non-multi-ligual-German-Application in which they used jumploader. But in that application, I am unable to see resumable functionality. Scratching my head against their documentation, i found out http : // jumploader.com / doc_resume.html It tells that jumploader has resume functionality in Cross session resume, the one i am looking for (if the user close the browser the new session gets hold on uncompleted uploaded files from the old session against the user id). But I cant find any example on their demos page which actually pause/RESUME functionality in a continuous manner! Is it even possible to achieve that kind of resumable functionality. Please tell me about any options/example/demos preferable deployed in rails. I shall be very much obliged. ~ Thanks

• How do I capture keystrokes on the web?

  - by Sean

  Using PHP, JS, or HTML (or something similar) how would I capture keystokes? Such as if the user presses ctrl+f or maybe even just f, a certain function will happen. ++++++++++++++++++++++++EDIT+++++++++++++++++++ Ok, so is this correct, because I can't get it to work. And I apologize for my n00bness is this is an easy question, new to jQuery and still learning more and more about JS. <script> var element = document.getElementById('capture'); element.onkeypress = function(e) { var ev = e || event; if(ev.keyCode == 70) { alert("hello"); } } </script> <div id="capture"> Hello, Testing 123 </div> ++++++++++++++++EDIT++++++++++++++++++ Here is everything, but I can't get it to work: <link rel="icon" href="favicon.ico" type="image/x-icon"> <style> * { margin: 0px } div { height: 250px; width: 630px; overflow: hidden; vertical-align: top; position: relative; background-color: #999; } iframe { position: absolute; left: -50px; top: -130px; } </style> <script> document.getElementsByTagName('body')[0].onkeyup = function(e) { var ev = e || event; if(ev.keyCode == 70 && ev.ctrlKey) { //control+f alert("hello"); } } </script> <div id="capture"> Hello, Testing 123<!--<iframe src="http://www.pandora.com/" scrolling="no" width="1000" height="515"frameborder="0"></iframe>--> </div>

• Intercepting mouse events using a global hook. Stop an action from happening.

  - by fMinkel

  I'm attempting to intercept and interrupt mouse events. Lets say I wanted to disable the right mouse button down event, or even the mouse move event. I haven't been able to figure out the interrupting part. I am using the (I assume pretty widely used) following code for Global Hooking of the mouse. Private Structure MSLLHOOKSTRUCT Public pt As Point Public mouseData As Int32 Public flags As Int32 Public time As Int32 Public extra As IntPtr End Structure Private _mouseHook As IntPtr Private Const WH_MOUSE_LL As Int32 = 14 Private Delegate Function MouseHookDelegate(ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32 <MarshalAs(UnmanagedType.FunctionPtr)> Private _mouseProc As MouseHookDelegate Private Declare Function SetWindowsHookExW Lib "user32.dll" (ByVal idHook As Int32, ByVal HookProc As MouseHookDelegate, ByVal hInstance As IntPtr, ByVal wParam As Int32) As IntPtr Private Declare Function UnhookWindowsHookEx Lib "user32.dll" (ByVal hook As IntPtr) As Boolean Private Declare Function CallNextHookEx Lib "user32.dll" (ByVal idHook As Int32, ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32 Private Declare Function GetCurrentThreadId Lib "kernel32.dll" () As Integer Private Declare Function GetModuleHandleW Lib "kernel32.dll" (ByVal fakezero As IntPtr) As IntPtr Public Function HookMouse() As Boolean Debug.Print("Mouse Hooked") If _mouseHook = IntPtr.Zero Then _mouseProc = New MouseHookDelegate(AddressOf MouseHookProc) _mouseHook = SetWindowsHookExW(WH_MOUSE_LL, _mouseProc, GetModuleHandleW(IntPtr.Zero), 0) End If Return _mouseHook <> IntPtr.Zero End Function Public Sub UnHookMouse() Debug.Print("Mouse UnHooked") If _mouseHook = IntPtr.Zero Then Return UnhookWindowsHookEx(_mouseHook) _mouseHook = IntPtr.Zero End Sub Private Function MouseHookProc(ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32 'Debug.Print("Message = {0}, x={1}, y={2}", wParam.ToInt32, lParam.pt.X, lParam.pt.Y) If wParam.ToInt32 = 513 Then '''interrupt the left mouse button event here, but don't know what to return to do so.

• Mysterious Flickering Visual Artifact

  - by Axis

  A flashing bar of red appears at the top of the EAGLView that I have added as a subview in my iPhone app. It flickers on and off (i.e., one frame it's there, the next frame it's not, the next frame it's there again). I have removed a lot of code from my app until I'm essentially left with the stock OpenGL-ES project and a few changes: The glview is not fullscreen; it's a subview. I enabled the depth buffer. I'm not even trying to draw anything. If the glview is fullscreen, or if I disable the depth buffer, then there is no flicker and it works fine. But needless to say, this is a 3D view and I'd like to be able to display it within a larger UIKit view. I'm not sure what code would be useful to post, but here's how I add the glview to my main view: appDelegate.glView.frame = CGRectMake(245, 65, 215, 215); [self.view addSubview:appDelegate.glView]; [appDelegate.glView startAnimation]; Here's my render function: - (void) render { [EAGLContext setCurrentContext:context]; glBindFramebufferOES(GL_FRAMEBUFFER_OES, defaultFramebuffer); glViewport(0, 0, backingWidth, backingHeight); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glBindRenderbufferOES(GL_RENDERBUFFER_OES, colorRenderbuffer); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } It seems pretty obvious to me that the problem lies with the depth buffer somehow, but I'm not sure why. Also, it works fine in the simulator, but not on my iphone. I'm using iPhone OS 3.1. Any ideas on where to look for a problem?

• CSS - How to create a table cell with a two-colour background?

  - by Chris

  Hi, I'm trying to create an HTML table cell with a two-tone background; so I have normal text on a background which is yellow on the left, and green on the right. The closest I've got so far is as follows. The background is correctly half-and-half, but the content text is displaced below it. <html> <head> <style type='text/css'> td.green { background-color: green; padding: 0px; margin: 0px; height:100%; text-align:center } div.yellow { position:relative; width: 50%; height: 100%; background-color:yellow } </style> </head> <body style="width: 100%"> <table style="width: 25%"> <tr style="padding: 0px; margin: 0px"> <td class="green"> <div class="yellow"></div> <div class="content">Hello</div> </td> </tr> </table> </body> </html> How can I fix this up?

• Efficient update of SQLite table with many records

  - by blackrim

  I am trying to use sqlite (sqlite3) for a project to store hundreds of thousands of records (would like sqlite so users of the program don't have to run a [my]sql server). I have to update hundreds of thousands of records sometimes to enter left right values (they are hierarchical), but have found the standard update table set left_value = 4, right_value = 5 where id = 12340; to be very slow. I have tried surrounding every thousand or so with begin; .... update... update table set left_value = 4, right_value = 5 where id = 12340; update... .... commit; but again, very slow. Odd, because when I populate it with a few hundred thousand (with inserts), it finishes in seconds. I am currently trying to test the speed in python (the slowness is at the command line and python) before I move it to the C++ implementation, but right now this is way to slow and I need to find a new solution unless I am doing something wrong. Thoughts? (would take open source alternative to SQLite that is portable as well)

• Is this a safe way to release resources in Java?

  - by palto

  Usually when code needs some resource that needs to be released I see it done like this: InputStream in = null; try{ in = new FileInputStream("myfile.txt"); doSomethingWithStream(in); }finally{ if(in != null){ in.close(); } } What I don't like is that you have to initialize the variable to null and after that set it to another value and in the finally block check if the resource was initialized by checking if it is null. If it is not null, it needs to be released. I know I'm nitpicking, but I feel like this could be done cleaner. What I would like to do is this: InputStream in = new FileInputStream("myfile.txt"); try{ doSomethingWithStream(in); }finally{ in.close(); } To my eyes this looks almost as safe as the previous one. If resource initialization fails and it throws an exception, there's nothing to be done(since I didn't get the resource) so it doesn't have to be inside the try block. The only thing I'm worried is if there is some way(I'm not Java certified) that an exception or error can be thrown between operations? Even simpler example: Inputstream in = new FileInputStream("myfile.txt"); in.close(); Is there any way the stream would be left open that a try-finally block would prevent?

• Are TestContext.Properties usable ?

  - by DBJDBJ

  Using Visual Studio generate Test Unit class. Then comment in, the class initialization method. Inside it add your property, using the testContext argument. Upon test app startup this method is indeed called by the testing infrastructure. //Use ClassInitialize to run code before running the first test in the class [ClassInitialize()] public static void MyClassInitialize(TestContext testContext) { /* * Any user defined testContext.Properties * added here will be erased after this method exits */ testContext.Properties.Add("key", 1 ) ; // place the break point here } After leaving MyClassInitialize, any properties added by user are lost. Only the 10 "official" ones are left. Actually TestContext gets overwritten, with the inital offical one, each time before each test method is called. It it not overwritten only if user has test initialization method, the changes made over there are passed to the test. //Use TestInitialize to run code before running each test [TestInitialize()]public void MyTestInitialize(){ this.TestContext.Properties.Add("this is preserved",1) ; } This effectively means TestContext.Properties is "mostly" read only, for users. Which is not clearly documented in MSDN. It seems to me this is very messy design+implementation. Why having TestContext.Properties as an collection, at all ? Users can do many other solutions to have class wide initialization. Please discuss. --DBJ

• Is it possible to spoof or reuse VIEWSTATE or detect if it is protected from modification?

  - by Peter Jaric

  Question ASP and ASP.NET web applications use a value called VIEWSTATE in forms. From what I understand, this is used to persist some kind of state on the client between requests to the web server. I have never worked with ASP or ASP.NET and need some help with two questions (and some sub-questions): 1) Is it possible to programmatically spoof/construct a VIEWSTATE for a form? Clarification: can a program look at a form and from that construct the contents of the base64-encoded VIEWSTATE value? 1 a) Or can it always just be left out? 1 b) Can an old VIEWSTATE for a particular form be reused in a later invocation of the same form, or would it just be luck if that worked? 2) I gather from http://msdn.microsoft.com/en-us/library/ms972976.aspx#viewstate_topic12 that it is possible to turn on security so that the VIEWSTATE becomes secure from spoofing. Is it possible for a program to detect that a VIEWSTATE is safeguarded in such a way? 2 a) Is there a one-to-one mapping between the occurrence of EVENTVALIDATION values and secure VIEWSTATEs? Regarding 1) and 2), if yes, can I have a hint about how I would do that? For 2) I am thinking I could base64-decode the value and search for a string that always is found in unencrypted VIEWSTATEs. "First:"? Something else? Background I have made a small tool for detecting and exploiting so called CSRF vulnerabilities. I use it to quickly make proof of concepts of such vulnerabilities that I send to the affected site owners. Quite often I encounter these forms with a VIEWSTATE, and these I don't know if they are secure or not. Edit 1: Clarified question 1 somewhat. Edit 2: Added text in italics.

• Do you ever make a code change and just test rather than trying to fully understand the change you'v

  - by Clay Nichols

  I'm working in a 12 year old code base which I have been the only developer on. There are times that I'll make a a very small change based on an intuition (or quantum leap in logic ;-). Usually I try to deconstruct that change and make sure I read thoroughly the code. However sometimes, (more and more these days) I just test and make sure it had the effect I wanted. (I'm a pretty thorough tester and would test even if I read the code). This works for me and we have surprisingly (compared to most software I see) few bugs escape into the wild. But what I'm wondering is whether this is just the "art" side of coding. Yes, in an ideal world you would exhaustively read every bit of code that your change modified, but I in practice, if you're confident that it only affects a small section of code, is this a common practice? I can obviously see where this would be a disastrous approach in the hands of a poor programmer. But then, I've seen programmers who ostensibly are reading the code and break stuff left and right (in their own code based which only they have been working on).

• Modifying DIV CSS properties from within a deeply nested IFRAME.

  - by clintboxe

  I'm working with a business intelligence tool that only gives me access to a deeply nested iframe to add code. Ideally I would like to use jQuery and/or plain old JavaScript to modify the left and position CSS of a div that is 3 iframes above my IFRAME. I have access to add JavaScript/HTML to divArea0_1 within the reportiframe IFRAME. I would like to modify the propdiv DIV contained within the JSTabbedPanel IFRAME. Hopefully the HTML below is legible enough. :) Any ideas or help is greatly appreciated. <html> <div id = "tabs"> <iframe id = "tabbedPanel"> <iframe id = "JSTabbedPanel"> <div id = "treeTypeDiv"> <div id = "treediv"> <iframe id = "treeFrame"></iframe> </div> <div id = "propdiv"> <iframe id = "propFrame"> <div id = "reportpane"> <iframe id = "reportiframe"> <div id = "divEntire"> <div id = "divArea0_1"> <div id = "MyCode goes HERE"></div> </div> </div> </iframe> </div> </iframe> </div> </div> </iframe> </iframe> </div> </html>

• Modify columns in a data frame in R more cleanly - maybe using with() or apply()?

  - by Mittenchops

  I understand the answer in R to repetitive things is usually "apply()" rather than loop. Is there a better R-design pattern for a nasty bit of code I create frequently? So, pulling tabular data from HTML, I usually need to change the data type, and end up running something like this, to convert the first column to date format (from decimal), and columns 2-4 from character strings with comma thousand separators like "2,400,000" to numeric "2400000." X[,1] <- decYY2YY(as.numeric(X[,1])) X[,2] <- as.numeric(gsub(",", "", X[,2])) X[,3] <- as.numeric(gsub(",", "", X[,3])) X[,4] <- as.numeric(gsub(",", "", X[,4])) I don't like that I have X[,number] repeated on both the left and ride sides here, or that I have basically the same statement repeated for 2-4. Is there a very R-style way of making X[,2] less repetitive but still loop-free? Something that sort of says "apply this to columns 2,3,4---a function that reassigns the current column to a modified version in place?" I don't want to create a whole, repeatable cleaning function, really, just a quick anonymous function that does this with less repetition.

• cannot eliminate space between 2 horizontal divs inside containing div

  - by wantTheBest

  Should be easy, right? Just set the outer containing div's padding to zero, and set the two side-by-side divs inside the outer div to have margin:0 but that's having no effect on the space between the 2 horizontal divs. What I need is the red-outlined left div to touch the green-outlined right-side div. Despite my effort using padding and margin, the space between the 2 divs will not go away. I have looked at many answers on SO but so far no one's broken it down to this simple example -- my fiddle shows this issue, at http://jsfiddle.net/Shomer/tLZrm/7/ And here is the very simple code: <div style="border: 4px solid blue; white-space:nowrap; margin:0; padding:0; width:80%"> <div style="display:inline-block; width:45%; overflow:hidden; margin:0; border: 1px solid red"> Flimmy-flammy </div> <div style="display:inline-block; width:50%; overflow:hidden; margin:0px; border: 1px solid green"> Hambone-Sammy </div> </div>

• Evaluate an expression tree

  - by Phronima

  Hi, This project that I'm working on requires that an expression tree be constructed from a string of single digit operands and operators both represented as type char. I did the implmentation and the program up to that point works fine. I'm able to print out the inorder, preorder and postorder traversals in the correct way. The last part calls for evaulating the expression tree. The parameters are an expression tree "t" and its root "root". The expression tree is ((3+2)+(6+2)) which is equal to 13. Instead I get 11 as the answer. Clearly I'm missing something here and I've done everything short of bashing my head against the desk. I would greatly appreciate it if someone can point me in the right direction. (Note that at this point I'm only testing addition and will add in the other operators when I get this method working.) public int evalExpression( LinkedBinaryTree t, BTNode root ) { if( t.isInternal( root ) ) { int x = 0, y = 0, value = 0; char operator = root.element(); if( root.getLeft() != null ) x = evalExpression(t, t.left( root ) ); if( root.getRight() != null ) y = evalExpression(t, t.right( root ) ); if( operator == '+' ) { value = value + Character.getNumericValue(x) + Character.getNumericValue(y); } return value; } else { return root.element(); } }

• CSS to create curved corner between two elements?

  - by Tauren

  My UI has an unordered list on the left. When a list item is selected, a div appears on the right of it. I'd like to have a curved outer corner where the <li> and the <div> meet. See the white arrow in the image below. To extend the blue <li> to the edge of the <ul>, I'm planning to do something like this: li { right-margin: 2em; border-radius: 8px; } li.active { right-margin: 0; border-bottom-right-radius: 0; border-top-right-radius: 0; } Is there a better way to extend the <li> to the edge of the <ul>? Obviously, I'll include the webkit and mozilla border radius CSS as well. The main thing I'm unsure about is that outer corner underneath the bottom right corner of the active <li>. I have some ideas, but they seem like hacks. Any suggestions? NOTE that the <ul> is indicated in grey, but it would be white in the real design. Also, I'm planning to use Javascript to position the <div> correctly when an <li> is selected.

• Is there a better way to keep track of session variable creation/access throughout different pages?

  - by Brandon

  Here's what I am working on. At my website I have multiple processes with each one containing multiple steps. Now in one of the processes, there is an error checking routine executed before proceeding to the next step of that process. A session var is set indicating the error status and it will either redirect back to the referrer or display the next page's contents. Now this kind of functionality, I believe, is common throughout web development. The issue that is occurring is that session vars are left around and are not being cleaned up properly. At times this introduces undesired behavior. My website is growing and I find that I am requiring more and more session vars to keep track of different system and error states. So I was thinking about creating a kind of "session variable keeper" to keep track of session var usage. The idea is fairly simple. It will have the notion of a context (e.g. registration process) and allow access to a predefined set of session vars within that context. In addition, the var and context will be paired with an action to proceed to some form of event handling. So if you haven't noticed I'm new to web development. Any thoughts or comments on the idea that I am proposing would be greatly appreciated. The back-end is written in PHP/MySQL.

• JSF myfaces dataTable , how to avoid NBSP; tags in the TDs

  Hi, I have style applied to the TD elements of the dataTable of my myfaces application. td.financialReportTd { font-family: Arial; font-size: 12px; line-height: 12px; color:black; background-color: white; padding-right: 5px; text-align: right; border:0px black solid; height: 30px; padding-top:4px; padding-left:4px; vertical-align: top; direction: rtl; } Output: <td class="financialReportTd"> &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;MY TEXT </td> No matter what I try, those NBSP tags fill up the TD and position of the text changes to the worse. I tried style text-align:right; (I need RTL text), I tried direction: rtl; Nothing helps. How can I align my text to the very right of the TD and avoid those space tags?

• Wrong values reported by pyPDF for various box regions

  - by romor

  Using pyPdf, for most files I get matched results concerning various box's dimensions compared to what Acrobat reports. However for some files I get different values reported by pyPdf and Acrobat, like: pyPdf: artBox: 595.3 x 841.9 bleedBox: 595.3 x 841.9 cropBox: 595.3 x 841.9 trimBox: 517.3 x 754 Acrobat: artBox: 439.35 x 666.13 pt bleedBox: 439.35 x 666.13 pt cropBox: 439.35 x 666.13 pt trimBox: 439.35 x 666.13 pt I thought it's units issue, but then ratio between widths and heights doesn't match also, not mentioning trimBox mismatch Correct results are those reported by Acrobat of course. Does someone know why is this and is there a way I get correct dimensions by using pyPdf? Thanks couple of minutes later... After reading this question: Are PDF box coordinates relative or absolute? I figured I didn't considered uper left corner to be different then 0 (zero). It turned out that box starts at 77.95 x 87.87, so if we reduce reported values of trimBox by this values correct result is obtained. artBox: 0 x 0 bleedBox: 0 x 0 cropBox: 0 x 0 trimBox: 77.95 x 87.87 Other boxes seem with misleading values or I misinterpret them. Snippet: from pyPdf import PdfFileReader pdfread = PdfFileReader(file('my.pdf', 'rb')) page = 1 width = pdfread.getPage(page).trimBox[2]-pdfread.getPage(page).trimBox[0] height = pdfread.getPage(page).trimBox[3] - pdfread.getPage(page).trimBox[1] print width, height

• Populating PDF Fields using FDFACX

  - by NWilliams

  I was recently asked to preform some updates to an existing PDF document. The changes required were completed using Adobe Designer (the only tool I have available to me). These changes included alignment, and new text. Note that there were fillable form fields on the forms, and they were left untouched. The saved version of the form was then put into our ASP.NET application, which pre-populates the form fields were applicable (things like name, address etc... things we have in our database). For some reason, the new form does not populate. I've confirmed that the form fields have the correct names, that the actual file (the pdf) that is being pre-populated has the same permissions as others that are working. There are no errors thrown, and no difference in a step through with a working form and a non-working form. This is a legacy project and I have no real experience with the PDF populator they are using ... FDFACX .NET? And can't find a lot of info on it online. Any ideas?

• How much does an InnoDB table benefit from having fixed-length rows?

  - by Philip Eve

  I know that dependent on the database storage engine in use, a performance benefit can be found if all of the rows in the table can be guaranteed to be the same length (by avoiding nullable columns and not using any VARCHAR, TEXT or BLOB columns). I'm not clear on how far this applies to InnoDB, with its funny table arrangements. Let's give an example: I have the following table CREATE TABLE `PlayerGameRcd` ( `User` SMALLINT UNSIGNED NOT NULL, `Game` MEDIUMINT UNSIGNED NOT NULL, `GameResult` ENUM('Quit', 'Kicked by Vote', 'Kicked by Admin', 'Kicked by System', 'Finished 5th', 'Finished 4th', 'Finished 3rd', 'Finished 2nd', 'Finished 1st', 'Game Aborted', 'Playing', 'Hide' ) NOT NULL DEFAULT 'Playing', `Inherited` TINYINT NOT NULL, `GameCounts` TINYINT NOT NULL, `Colour` TINYINT UNSIGNED NOT NULL, `Score` SMALLINT UNSIGNED NOT NULL DEFAULT 0, `NumLongTurns` TINYINT UNSIGNED NOT NULL DEFAULT 0, `Notes` MEDIUMTEXT, `CurrentOccupant` TINYINT UNSIGNED NOT NULL DEFAULT 0, PRIMARY KEY (`Game`, `User`), UNIQUE KEY `PGR_multi_uk` (`Game`, `CurrentOccupant`, `Colour`), INDEX `Stats_ind_PGR` (`GameCounts`, `GameResult`, `Score`, `User`), INDEX `GameList_ind_PGR` (`User`, `CurrentOccupant`, `Game`, `Colour`), CONSTRAINT `Constr_PlayerGameRcd_User_fk` FOREIGN KEY `User_fk` (`User`) REFERENCES `User` (`UserID`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `Constr_PlayerGameRcd_Game_fk` FOREIGN KEY `Game_fk` (`Game`) REFERENCES `Game` (`GameID`) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=INNODB CHARACTER SET utf8 COLLATE utf8_general_ci The only column that is nullable is Notes, which is MEDIUMTEXT. This table presently has 33097 rows (which I appreciate is small as yet). Of these rows, only 61 have values in Notes. How much of an improvement might I see from, say, adding a new table to store the Notes column in and performing LEFT JOINs when necessary?

• Prevent Word from Reformatting my HTML

  - by Jonathan

  I have an HTML page that needs to open in word. I created the document in word and saved the document as an HTML document. So word spits out all its nasty HTML syntax. This is the opened through internet explorer which will display the word document within the browser. When I view the page word modifies some of the tags. More specifically it adds a Width and Height tag and ignores the width and height within the style tag. If I try setting the Width and Height tags it overrides with new values. I have tested on different environments and get different results as word makes decision how to handle. A bit of background this img starts off as this, and is rendered via data rendering syntax. <asp:Image id="as" runat="server" Src"<%# ImgSource %>" style="width:178px;height:130px" /> It ends up like this in word <img width=32 height=32 id=barCodeImage src="http://myurl/BarcodeImages/1136574_129180418198008169.png" style='border-bottom-width:0px;border-left-width:0px;border-right-width:0px; border-top-width:0px;height:130px;width:178px'> I want to stop word from reformatting the HTML.

I'd like for the options to show up at the top and grow downwards, and to have "save," "delete," and "cancel" buttons which show up at the very bottom of the screen (if there is space left in between the bottom of all the options and the top of the buttons). Here's a screenshot of my attempt: http: //img375.imageshack.us/img375/3628/10370572.png (StackOverflow was only letting me post a single link so you'll have to get rid of the space in between http: and the rest) As you can see, the buttons show up directly below the options rather than at the bottom of the screen. In fact the top level (green) linearlayout doesn't even extend all the way down, despite having a height of fill_parent and a weight of 1 (and the blue is the scrollview, so there is room to expand). I've tried every possible combination of heights, weights, gravities, and anything else to get this working and still can't do it. Everytime I pasted my xml layout into here, the top and bottom portions got cut off, so instead I pasted it here: pastey link Can anyone see what I'm doing wrong?

• Link failure with either abnormal memory consumption or LNK1106 in Visual Studio 2005.

  - by Corvin

  Hello, I am trying to build a solution for windows XP in Visual Studio 2005. This solution contains 81 projects (static libs, exe's, dlls) and is being successfully used by our partners. I copied the solution bundle from their repository and tried setting it up on 3 similar machines of people in our group. I was successful on two machines and the solution failed to build on my machine. The build on my machine encountered two problems: During a simple build creation of the biggest static library (about 522Mb in debug mode) would fail with the message "13libd\ui1d.lib : fatal error LNK1106: invalid file or disk full: cannot seek to 0x20101879" Full solution rebuild creates this library, however when it comes to linking the library to main .exe file, devenv.exe spawns link.exe which consumes about 80Mb of physical memory and 250MB of virtual and spawns another link.exe, which does the same. This goes on until the system runs out of memory. On PCs of my colleagues where successful build could be performed, there is only one link.exe process which uses all the memory required for linking (about 500Mb physical). There is a plenty of hard drive space on my machine and the file system is NTFS. All three of our systems are similar - Core2Quad processors, 4Gb of RAM, Windows XP SP3. We are using Visual studio installed from the same source. I tried using a different RAM and CPU, using dedicated graphics adapter to eliminate possibility of video memory sharing influencing the build, putting solution files to different location, using different versions of VS 2005 (Professional, Standard and Team Suite), changing the amount of available virtual memory, running memtest86 and building the project from scratch (i.e. a clean bundle). I have read what MSDN says about LNK1106, none of the cases apply to me except for maybe "out of heap space", however I am not sure how I should fight this. The only idea that I have left is reinstalling the OS, however I am not sure that it would help and I am not sure that my situation wouldn't repeat itself on a different machine. Would anyone have any sort of advice for me? Thanks
