  • Is there a way to change the maximum width of a window without using the WM_GETMINMAXINFO message?

    - by David
    I want to change the imposed Windows maximum width that a window can be resized to, for an external application's window (not my C#/WinForms program's window). The documentation of GetSystemMetrics for SM_CXMAXTRACK says: "The default maximum width of a window that has a caption and sizing borders, in pixels. This metric refers to the entire desktop. The user cannot drag the window frame to a size larger than these dimensions. A window can override this value by processing the WM_GETMINMAXINFO message." Is there a way to modify this SM_CXMAXTRACK value (either system wide or for one particular window), without processing the WM_GETMINMAXINFO message? Maybe an undocumented function, a registry setting, etc.? (Or: The documentation for MINMAXINFO.ptMaxTrackSize says: "This value is based on the size of the virtual screen and can be obtained programmatically from the system metrics SM_CXMAXTRACK and SM_CYMAXTRACK." Maybe there is a way to change the size of the virtual screen?) Thank you

  • jQuery UI - Datepicker - Hide year

    - by David
    Hi, I'm using jQuery UI 1.8 and I would like to hide the year from the user in both the popup and the textbox. Essentially instead of picking the day, month and year I want the user to just pick the day and month. Hiding the year in the textbox is easy enough, the code shown below will do that. I'm stumped on how to hide the year from the popup - so it would say "April" instead of "April 2010". $(function() { $("#beginDateRange").datepicker({ dateFormat: 'mm/dd' }); }); <input type="text" name="beginDateRange" id="beginDateRange" /> Any help would be greatly appreciated.

  • How to present the same modalView after dismissing it once

    - by David Casillas
    I'm having some problem trying to present a modal view controller after it has been presented the first time, so I just start a little test method, it presents, dismisses and presents again the same controller modally. // This is just test Code. MYViewController *vc = [[MYViewController alloc] init]; [self presentModalViewController:vc animated:YES]; [self dismissModalViewControllerAnimated:YES]; [self presentModalViewController:vc animated:YES]; I get the error: 2011-11-15 09:50:42.678 Proyecto3[1260:11603] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Application tried to present modally an active controller <RootViewController: 0x6d9d090>.' The documentation does not add any clue here.

  • CodeCharge : is it any good?

    - by David Burrows
    Hi, A job came in to me that's built with CodeCharge - had a look at it and seems to be a pretty basic point-and-click site builder tool. Has anyone got any in-depth experience with it? My first reaction is one of horror and to just rebuild the code in Rails or PHP but I thought I'd ask the question first, maybe i'm missing something...

  • Improve my php image resizer to support alpha png and transparent GIFs

    - by David
    Hi, I use this function to resize images but i end up with ugly creepy image with a black background if it's a transparent GIF or PNG with alpha, however it works perfectly for jpg and normal png. function cropImage($nw, $nh, $source, $stype, $dest) { $size = getimagesize($source); $w = $size[0]; $h = $size[1]; switch($stype) { case 'gif': $simg = imagecreatefromgif($source); break; case 'jpg': $simg = imagecreatefromjpeg($source); break; case 'png': $simg = imagecreatefrompng($source); break; } $dimg = imagecreatetruecolor($nw, $nh); switch ($stype) { case "png": imagealphablending( $dimg, false ); imagesavealpha( $dimg, true ); $transparent = imagecolorallocatealpha($dimg, 255, 255, 255, 127); imagefilledrectangle($dimg, 0, 0, $nw, $nh, $transparent); break; case "gif": // integer representation of the color black (rgb: 0,0,0) $background = imagecolorallocate($simg, 0, 0, 0); // removing the black from the placeholder imagecolortransparent($simg, $background); break; } $wm = $w/$nw; $hm = $h/$nh; $h_height = $nh/2; $w_height = $nw/2; if($w> $h) { $adjusted_width = $w / $hm; $half_width = $adjusted_width / 2; $int_width = $half_width - $w_height; imagecopyresampled($dimg,$simg,-$int_width,0,0,0,$adjusted_width,$nh,$w,$h); } elseif(($w <$h) || ($w == $h)) { $adjusted_height = $h / $wm; $half_height = $adjusted_height / 2; $int_height = $half_height - $h_height; imagecopyresampled($dimg,$simg,0,-$int_height,0,0,$nw,$adjusted_height,$w,$h); } else { imagecopyresampled($dimg,$simg,0,0,0,0,$nw,$nh,$w,$h); } imagejpeg($dimg,$dest,100); } I use php 5.3.2 and the GD library bundled (2.0.34 compatible) Thanks

  • Casting Generic Types

    - by David Rutten
    Public Function CastToT(Of T)(ByVal GenericType(Of Object) data) As GenericType(Of T) Return DirectCast(data, GenericType(Of T)) End Function The above clearly does not work. Is there any way to perform this cast if I know that all objects inside data are in fact of Type T?

  • How do I solve "Two different CRTLDLLs are loaded" when using packages in C++ Builder 2010?

    - by David M
    Hi, We are trying to split up our monolithic EXE into a combination of an EXE and several packages. So far, we have one package that we're trying to use, and when running the EXE Codeguard shows the following error on startup: CG Error Two different CRTLDLLs are loaded. CG might report false errors (C:\Windows\system32\CC32100MT.DLL) (D:\Projects\Foo\Bar.bpl) OK I read this as two different runtime libraries being loaded - one, the correct one (CC32100MT.dll), one incorrect, which is the package we're trying to use. Continuing to run the program shows odd errors, especially casting between classes or passing a pointer to a class as a parameter in a method that crosses the EXE/DLL boundary. Codeguard itself doesn't show any other errors at all though. How do we solve this? Some more details We've looked at as many things as we (the developer working on this and I) can collectively think of: Each project is built using runtime packages. The EXE host lists Bar in its package list. Each project is set to compile with dynamic RTL. However, changing this does not solve the problem. The package is linked to the EXE via its BPI file, but linking via a LIB makes no difference either. The EXE and BPL are compiled with the same project settings, where the same options exist for both types of project. We think, anyway :) There is only one copy of the BPL and BPI on the system: it's definitely linking to the right one. Examining the EXE and BPL with Depends and TDump show they are both using C:\Windows\system32\CC32100MT.DLL. They should both be using the one RTL. Creating a new project (a plain VCL forms application) and linking to the BPL (via its BPI) works fine. Something in the process of adding all the files and LIBs that make our EXE contain the code it needs to changes this, but we haven't been able to figure out what. The LIBs all either correspond to DLLs we use (flat C interface, usually look as though they were built with MSVC) or are simple projects with lots of related files, compiled to a lib for the purpose of linking into the EXE - these correspond roughly to the areas of the program we want to split to BPLs, by the way. There don't seem to be project options for the LIB projects that would affect RTL linking, unless we've missed them. I have exhaustively hunted through Depends and looked at all RTL and CC32*.dll files the EXE and every single DLL references. All are identical: rtl140.bpl and CC32100MT.DLL. Fully qualified paths show they are the same files, too. Everything should be using the one same run-time library. We're stumped. Absolutely stumped. We've had other problems using BPLs (they seem to be surprisingly tricky things, especially using C++) but have managed to solve them all. This one we've had no luck at all and we'd really appreciate any insights :) We're using C++Builder 2010 (as part of RAD Studio actually, but with little Delphi code apart from components.)

  • How do I prevent a font from extending off the top of a textbox?

    - by David Ellis
    I'm using a barcode font (IDAutomationMC39H) in an SSRS 2005 report I'm developing, and while it renders fine in the preview in BIDS, if I export the results to PDF, print the results, or do any of the above (including preview) in Report Manager, the barcode font is extending off the top of the textbox. The barcode itself is nearly 20px tall, even at only a 12pt size. I've tried changing the CanGrow value for the textbox, but it seems that even with that set off the barcode isn't pushing the bottom edge of the textbox downwards, it's simply extending over the top of the box. I've also tried resizing the textbox to allow it to contain the entire height of the font, but even with the VerticalAlign set to Bottom the barcode still sticks to the top of the textbox and overflows out the top. See screenshot here: http://bit.ly/9UfycP Does anyone know how to force the font to be bound by the top of the box, instead of overlapping it?

  • getting the "this" that a function's caller was called with in JavaScript

    - by David Morrissey
    Is it possible to get the this that a function's caller was called with in JavaScript without passing this to the arguments in a way which supports IE as well as Firefox/Chrome et al? For example: var ob = { callme: function() { doSomething() } } function doSomething() { alert(doSomething.caller.this === ob) // how can I make this work? } ob.callme() I'm starting to suspect it's not, but I thought I may as well ask as it'd make my code much shorter and easier to read. Thanks for any information!

  • How do i change this method to get strings instead of ints

    - by David
    here is the original code: public static int getInt () { Scanner in = new Scanner (System.in) ; if (in.hasNextInt()) { int a = in.nextInt() ; return a ; } else { System.out.println ("try again:") ; return getInt () ; } } This checks and sees if the input it receives is an int. If it is then it returns the int, if not it tells you to try again and re-runs. This is what i tried to do to change it: public static String getIns () { Scanner in = new Scanner (System.in) ; if (in.hasNextString()) { String a = in.nextString() ; return a ; } else { System.out.println ("try again:") ; return getIns () ; } } This doesn't work though. I looked through the documentation for the scanner class and i think the problem is that there is no such method as in.hasNextString or in.nextString What methods from the scanner class can i use to do what i intend these to do?

  • Using struts.xml with convention plugin

    - by David Alt
    This seems like it should be easy to do, but I just can make it work. I'm hooked on the convention plugin in Struts 2.1. However, I need to define some package-level configuration such as a new interceptor stack and exception mappings. I'd like to use the struts.xml file for this, but I can't get the convention-based packages matched to the struts.xml packages. My struts.xml looks like: <struts> <constant name="struts.convention.default.parent.package" value="default"/> <package name="default" extends="struts-default"> </package> <package name="root" namespace="/" extends="struts-default"> <action name="index"> <result>/index.jsp</result> </action> </package> <package name="my.package.actions.myaccount" namespace="/myaccount" extends="struts-default"> <interceptors> <interceptor name="authenticationInterceptor" class="my.package.interceptors.AuthenticationInterceptor"/> <interceptor-stack name="secureStack"> <interceptor-ref name="authenticationInterceptor"/> <interceptor-ref name="defaultStack"/> </interceptor-stack> </interceptors> <default-interceptor-ref name="secureStack"/> </package> </struts> I have my interceptor in: /src/my/package/interceptors and my actions in: /src/my/package/actions/myaccount

  • A monkey could do this better - Access to and availability of private member functions in C++

    - by David
    I am wandering the desert of my brain. I'm trying to write something like the following: class MyClass { // Peripherally Related Stuff public: void TakeAnAction(int oneThing, int anotherThing) { switch(oneThing){ case THING_A: TakeThisActionWith(anotherThing); break; //cases THINGS_NOT_A: }; private: void TakeThisActionWith(int thing) { string outcome = new string; outcome = LookUpOutcome(thing); // Do some stuff based on outcome return; } string LookUpOutcome(int key) { string oc = new string; oc = MyPrivateMap[key]; return oc; } map<int, string> MyPrivateMap; Then in the .cc file where I am actually using these things, while compiling the TakeAnAction section, it [CC, the solaris compiler] throws an an error: 'The function LookUpOutcome must have a prototype' and bombs out. In my header file, I have declared 'string LookUpOutcome(int key);' in the private section of the class. I have tried all sorts of variations. I tried to use 'this' for a little while, and it gave me 'Can only use this in non-static member function.' Sadly, I haven't declared anything static and these are all, putatively, member functions. I tried it [on TakeAnAction and LookUp] when I got the error, but I got something like, 'Can't access MyPrivateMap from LookUp'. MyPrivateMap could be made public and I could refer to it directly, I guess, but my sensibility says that is not the right way to go about this [that means that namespace scoped helper functions are out, I think]. I also guess I could just inline the lookup and subsequent other stuff, but my line-o-meter goes on tilt. I'm trying desperately not to kludge it.

  • Using Qt's XML library for simple operation

    - by David Powers
    I basically want to use the XML parser from Qt in my existing project. I have only used Qt once before, and that was with Qt Designer, and I am not having much luck finding anything on Google about how to just use the XML library. I have downloaded a web page that has one large list, and I want to parse it and add each list item to a c++ list. I found this sample code on Ubuntu forums... http://www.uluga.ubuntuforums.org/showpost.php?p=9112973&postcount=6 I want to use that except I need to know what exactly I need to add to the project to get access to it. One other small question is QDomDocument seems to be for files (makes sense) but I have the XML in a string. What part of the XML library works for contents of a string?

  • How to code a batch file to copy and rename the most recently dated file?

    - by david.murtagh.keltie.com
    I'm trying to code a batch file to copy only the most recently dated file in a given folder to another directory on the local machine, and simultaneously rename it as it does. I've found a very similar question here http://stackoverflow.com/questions/97371/batch-script-to-copy-newest-file and have managed to cobble together the below code from other forums too, but have hit a brick wall as it only results in the batch file itself being copied to the destination folder. It doesn't matter to me where the batch file itself sits in order for this to run. The source folder is C:! BATCH and the destination folder is C:\DROP The code is below, apologies if this is a glaringly obvious answer but it's literally the first foray into coding batch files for me... Thanks! @echo off setLocal EnableDelayedExpansion pushd C:\! BATCH for /f "tokens=* delims= " %%G in ('dir/b/od') do (set newest=%%G) copy "!newest!" C:\DROP\ PAUSE

  • Application lifecycle. How to run something only when application starts

    - by David
    I have a dialog popup to indicate how long I want an activity to run. Seems simple enough, but its difficult to determine when the activity is really starting. If the user opens the keyboard on a G1 and thereby goes into landscape, that reruns the activities onCreate method. I can't have a static for the class or even create an application class, because I can't determine when the 'application' goes away. Even after destroying the only activity, the application is apparently still alive. Is there a way to determine that onCreate has been called because of the keyboard being extended or landscape mode invoked? Thanks

  • How to organize Enterprise scale Composite Applications (CAG)

    - by David
    All QuickStarts and RI examples in the CAG documentation are good but I lack the more Enterprise scale examples. Let's say we have 40+ modules, each containing a Proxy,Facade,PresentationModel,Model and Views. Each module also makes calls to a Module-specific WCF service which is to be hosted in IIS or in a stand-alone console host. Our approach have been to include the UI-module, service-module and related tests into one solution so they can be developed and tested separately from other modules. My problem is how the hosting of the services should be done when the services are in separate modules and how to actually run the separate module together with the rest of the application-modules when I press F5. Is there a best practise for this? I guess it has been done before?

  • How can I force a jQuery faded-in user control to remain after click events?

    - by David
    I have a basic page to which I'm adding an uploader control based on Bulk Uploader at c-sharpcorner.com and the control is in a jQuery-faded div based on yesdegisn The Bulk Uploader has two server side event handlers for two buttons--Add and Remove. After clicking these buttons, the fade disappears and you're back to the basic page--if the user needs to add more files, this is not desirable. The ArrayList of files added to a ListBox is maintained, but I have to click the "fade-in" link (LinkButton id="lnkDocumentUpload") to display this window again. I also need the control to POST to UploadPost.aspx, and it doesn't work either. Clicking the upload button(<asp:Button ID="btnUpload" runat="server" />) has the same behavior described above--fade disappears, data is retained, and no POST. I've surrounded the control with <form id="frmUpload" action="~/UploadPost.aspx"> ... <asp:Button ID="btnUpload" runat="server" Text="Upload"/> </form> A LinkButton activates the fade in jQuery via $("#lnkDocumentUpload").click(function() { centerPopup(); loadPopup(); });

  • How can I use the same buildscript for Flash Builder 4 and Ant/Mvn?

    - by David Laing
    I'm setting up a build system for a Flash Builder 4 (Flex 4) based project; and I'm struggling to get a setup that compiles in the IDE the same as it does from the command line on the build server. I come from a C# background; and my expectation is that I'll be able to create a "solution" with a collection of "projects" that I can compile from the IDE, or from the command line on the build server. The best I've managed sofar is 2 separate build "scripts", a custom ant script for the build server, and the default Flash Builder IDE config based on a workspace; but this is making my DRY daemons jump around in fury. Please can someone point me in the right direction :)

  • Project management: Implementing custom errors in VS compilation process

    - by David Lively
    Like many architects, I've developed coding standards through years of experience to which I expect my developers to adhere. This is especially a problem with the crowd that believes that three or four years of experience makes you a senior-level developer.Approaching this as a training and code review issue has generated limited success. So, I was thinking that it would be great to be able to add custom compile-time errors to the build process to more strictly enforce this and other guidelines. For instance, we use stored procedures for ALL database access, which provides procedure-level security, db encapsulation (table structure is hidden from the app), and other benefits. (Note: I am not interested in starting a debate about this.) Some developers prefer inline SQL or parametrized queries, and that's fine - on their own time and own projects. I'd like a way to add a compilation check that finds, say, anything that looks like string sql = "insert into some_table (col1,col2) values (@col1, @col2);" and generates an error or, in certain circumstances, a warning, with a message like Inline SQL and parametrized queries are not permitted. Or, if they use the var keyword var x = new MyClass(); Variable definitions must be explicitly typed. Do Visual Studio and MSBuild provide a way to add this functionality? I'm thinking that I could use a regular expression to find unacceptable code and generate the correct error, but I'm not sure what, from a performance standpoint, is the best way to to integrate this into the build process. We could add a pre- or post-build step to run a custom EXE, but how can I return line- and file-specifc errors? Also, I'd like this to run after compilation of each file, rather than post-link. Is a regex the best way to perform this type of pattern matching, or should I go crazy and run the code through a C# parser, which would allow node-level validation via the parse tree? I'd appreciate suggestions and tales of prior experience.

  • SQL 2005 w/ C# optimal "Paging"

    - by David Murdoch
    When creating a record "grid" with custom paging what is the best/optimal way to query the total number of records as well as the records start-end using C#? SQL to return paged record set: SELECT Some, Columns, Here FROM ( SELECT ROW_NUMBER() OVER (ORDER BY Column ASC) AS RowId, * FROM Records WHERE (...) ) AS tbl WHERE ((RowId > @Offset) AND (RowId <= (@Offset + @PageSize)) ) SQL to count total number of records: SELECT COUNT(*) FROM Records WHERE (...) Right now, I make two trips to the server: one for getting the records, and the other for counting the total number of records. What is/are the best way(s) to combine these queries to avoid multiple DB trips?
