• Retrieving cached data from existing Crystal Reports file

  - by TimS

  Is there any way to retrieve the cached data from a previously refreshed report and say, dump it to a file? Basically, I'm looking for the dataset that is being used by the report, and hand-dragging each field onto the canvas or even exporting the file doesn't quite get me where I want. I'm not particular to a specific solution, be it .NET, vbscripting or even within the program itself... I'm not overly familiar with the Crystal Report object model, nor .NET, but it seems like with a setting like "EnableSaveDataWithReport", there ought to be a straightforward way. Oh, and I'm on CR 11 Pro

• When creating a dialog with jquery, how do I hide the dialog div?

  - by stormist

  I am creating a dialog like in this page: http://jqueryui.com/demos/dialog/#modal-confirmation (click view source) on the bottom is the div that gets placed in the dialog. The dialog works perfect when called by the javascript but the dialog is apparent at the bottom of the page when it loads. (minus all the styling that gets applied when it is called by the javascript function) How can I hide the div and still allow the dialog to use it? I have tried setting style="visibility:hidden" but that prevents it from being shown when called by the javascript.

• PHP mkdir and apache ownership

  - by elcorazon

  Is there a way to set php running under apache to create folders with the folder owned by the owner of the program that creates it instead of being owned by apache? Using word press it creates new folders to upload into but these are owned by apache.apache and not by the site that they are running in. This also happens using ostickets. For now we have to SSH into the server and chmod the folder, but it would seem there would be a setting somewhere to override the ownership outside of any program that does it.

• windows mobile 6.5 Gestures and DirectDraw

  - by ArjanW

  I'm trying to build a UI using directdraw in c#. For this im using a DirectDrawWrapper as sugested here. My initial tests setting up the screen work perfectly. But now i'd like to incorporate gesture recognition into the UI. So i instantiate a GestureRecognizer and tie it to the _form which also gets passed to the DirectDrawGraphics constructor, form = new Form(); _form.show(); _graphics = new DirectDrawGraphics(_form, CooperativeFlags.Fullscreen, BackbufferMode.Any); gestureRecognizer = new GestureRecognizer(); gestureRecognizer.TargetControl = _form; Pasting the whole DirectDrawWrapper code might be a bit to much, so let me try to formulate a question. I guess directdraw talks directly to the video memory, as it should. But then my form wont receive any messages, thus any eventhandlers i'v tied op to the GestureRecognizer wont be fired. How can i still receive any messages from the touchscreen?

• Drawing an NSAttributedString into a non-rectangular CGPath?

  - by Adrian Kosmaczewski

  I generate a rather complex NSAttributedString in my iOS 3.2 application (iPad), including formatting options of type CTParagraphStyleSetting, in particular with values for kCTParagraphStyleSpecifierMinimumLineHeight and kCTParagraphStyleSpecifierParagraphSpacing. When I try to draw this attributed string into a non-rectangular CGPath, Core Text draws it but without the line spacing defined; that is, all text appears crammed in paragraphs without line spacing. Needless to say, it does not look as pretty as if the CGPath was simply defined using a single call to CGPathAddRect()! Is there any setting I can specify (to my CTFramesetterRef or to the CTFrameRef associated to the culprit CGPath) to avoid losing all line height information? Thanks!

• Hiding Row in DataGridView Very Slow

  - by Ed Schwehm

  I have a DataGridView in a Winforms app that has about 1000 rows (unbound) and 50 columns. Hiding a column takes a full 2 seconds. When I want to hide about half the rows, this becomes a problem. private void ShowRows(string match) { this.SuspendLayout(); foreach (DataGridViewRow row in uxMainList.Rows) { if (match == row.Cells["thisColumn"].Value.ToString())) { row.Visible = false; } else { row.Visible = true; } } this.ResumeLayout(); } I did some testing by adding by addingConsole.WriteLine(DateTime.Now)around the actions, androw.Visible = falseis definitely the slow bit. Am I missing something obvious, like setting IsReallySlow = false? Or do I have to go ahead and enable Virtual Mode and code up the necessary events?

• Properties.Settings Ambiguity after adding LINQ to SQL

  - by Emmanuel Smith

  I have recently linked a database to my C# service by creating a LINQ to SQL item in my solution. Everything was fine and dandy as I was continuing to code, but then I suddenly noticed that there where 16 Ambiguity errors. e.g. Ambiguity between 'EmailService.Properties.Settings.defaultInstance' and 'EmailService.Properties.Settings.defaultInstance' What happened was that the database file decided to create it's own Setting.Designer.cs; So now I have a Settings.Designer.cs and a Settings1.Designer.cs (which was created by the LINQ to SQL file) in my Properties folder. Is there anyway that I can change where the database file is referencing its settings so I can delete the duplicate?

• How do you redeploy javascript in Idea when using a Tomcat configuration

  - by Jonny Leeds

  I'm working on a java/javascript webapp that runs on tomcat. We're working with IDEA and I've managed to get debugging set up for both the client and server code at the same time, which is great. I did have hot redeployment of the javascript set up when running Tomcat manually, however I find when running Tomcat through IDEA this doesnt work as it's setting stuff up somewhere in my users folder. I was going to just set up a deployment configuration to go to that folder but I can't see any of the javascript files in there. Is it possible to get the best of both worlds and have debugging and automatic deployment working together?

• .NET Active Directory Password Expiration on Windows 2008

  - by Brent Pabst

  Searched SO and Everywhere else, including the .net developers guide to directory services programming book - no luck. I am trying to create a simple password reset web page that allows the user to change their password. The change password portion of the code is working fine. For the users I would also like to display when their current password will expire next. Using the sample code from the book mentioned above I was able to get all of the code setup however, the attribute that is returned is always equal to Long.MinValue and hence cannot be inverted to a positive number, plus this means it did not find the proper domain setting. Does anyone have sample code or references for getting the password expiration in a Windows 2008 or R2 domain environment where password policies can be different for each user?

• Flex: vertical gap between list items not working

  - by pfunc

  I have a list item with buttons in it like so: <mx:List contentBackgroundAlpha="0" baseColor="0x333333" leading="10" id="weekButtonList" width="260" borderVisible="false" dataProvider="{_data.mappoints.week.@number}" itemClick="onWeekClick(event);" > <mx:itemRenderer > <mx:Component> <mx:Button buttonMode="true" width="260" height="50" label="Week {data}" /> </mx:Component> </mx:itemRenderer> </mx:List> No matter what I do, these buttons have a vertical gap inbetween them. I have tried everything from setting the "vertical-gap" property to negative and positive numbers as well as changing the padding-bottom and padding-top on them. I want the buttons to be right up against eachother vertically. I have also tried "button-height" and padding on the List component...still nothing. How do I control this?

• Importing Swift classes within a Objective-C Framework

  - by theMonster

  I have a custom Framework that has a bunch of Objective-C Classes. Within the Framework, I'd like to add more classes using Swift. However, when trying to expose the Swift classes to the Objective-C code using: MyProduct-Swift.h, it comes up as "MyProduct-Swift.h file not found". I've tried this in a single view template and it works fine. Is it not possible to import Swift within a framework? I've also verified that I have set the Defines Module setting and the Module Name. I've tried it with and without these settings.

• DSP - How are frequency amplitudes modified using DFT?

  - by Trap

  I'm trying to implement a DFT-based equalizer (not FFT) for the sole purpose of learning. To check if it works I took an audio signal, analyzed it and then resynthesized it again with no modifications made to the frequency spectrum. So far so good. Now I tried to silence some frequency bands, just by setting their amplitudes to zero before resynthesis, but definitely it's not the way to go. What I get is a rather distorted signal. I'm using the so-called 'standard way of calculating the DFT' which is by correlation. I first tried to modify the real part amplitudes only, then modifying both the real and imaginary part amplitudes. I also tried to convert the DFT output to polar notation, then modifying the magnitude and convert back to rectangular notation, but none of this is working. Can someone show me what I'm doing wrong? I tried to find info on this subject in the internet but couldn't find any. Thanks in advance.

• Elmah on MVC website with WordPress/php sub directory

  - by creativeincode

  I have created a website using ASP.NET MVC and use ELMAH for error handling, this works perfectly. After setting up a virtual directory on my website under /blog and adding the necessary WordPress php files and mysql db, I get the below error come up. Could not load file or assembly 'Elmah' or one of its dependencies. The system cannot find the file specified. I think this has something to do with the fact that ELMAH is applying itself to all sub-directories. Is there a way that I can tell ELMAH to ignore everything under /blog? Or is there a way to get around this? Thanks in advance.

• How to handle application upgrades from free to paid version while preserving any data

  - by cdonner

  Here is the context. I want to have a free version and a premium version of the same application. When people buy the application, I want them to be able to "upgrade" without losing their data, i.e. the premium version should install over the free version. I want to use the same code base and just switch a setting to build the premium version. Andoid Market does not let me convert a free app to a paid app, so the trivial option is not available. I am curious if someone has tried this successfully. How does Android Market identify an application - will it think that the premium version is a different app and just install it in parallel?

• Date Picker Blue

  - by Matt Winters

  I'm successfully setting a date-picker with an initial date from a plist, but I see some unwanted blue values in the month, day, and year components, presumably corresponding to current date. So if today is April 18, 2010 and initial date being set is March 19, 2008, it looks like this (bold represents the blue): January 17 2006 February 18 2007 ------------------------------ March 19 2008 ------------------------------ April 20 2009 May 21 2010 First question is: How do I get rid of the blue? And second question: Ideally, how do I get it to look like this? January 17 2006 February 18 2007 ------------------------------ March 19 2008 ------------------------------ April 20 2009 May 21 2010 Third question, totally unrelated and not as important: How could I have gotten the above to show in blue rather than bold? I see blue in code snippets all the time. Matt

• UITextInput setMarkedText:selectedRange not working? (Can't be!)

  - by nacho4d

  I want to set the marked text programmatically and since iOS5 UITextView and UITextField conform to UITextInput this should be possible but for some reason I always get the markedText to be nil. :( What am I missing here? This is what I've tried without success: (While the textview is firstResponder) 1.- When the text view contains no text: text: "", selectedRange : {0,0}, markedText: nil. [_textView setMarkedText:@"?" selectedRange:NSMakeRange(0, 1)]; Result: text : "", selectedRange: {0,0}, markedText: nil. (Nothing changed) 2.- When the text view contains text + some marked text: text : "AAA", selectedRange = {0,3}, marked text at the end : "??" then I do: [_textView setMarkedText:@"?" selectedRangeNSMakeRange(0,3)]; Result : text :"AAA", selectedRange: {0,3}, markedText: nil; (the marked text became nil) In both cases is like setMarkedText:selectedRange: would be setting the current marked text (if some) to nil. Any help would be highly appreciated :)

• Record AVAudioPlayer output using AVAudioRecorder

  - by Kieran

  In my app the user plays a sound by pressing a button. There are several buttons which can be played simultaneously. The sounds are played using AVAudioPlayer instances. I want to record the output of these instances using AVAudioRecorder. I have set it all up and a file is created and records but when I play it back it does not play any sound. It is just a silent file the length of the recording. Does anyone know if there is a setting I am missing with AVAudioPlayer or AVAudioRecorder? Thanks

• PHP encoding with DOMDocument

  - by Olivier Lalonde

  <tag> ????? ? </tag> When I try to get the content of the following code using DOMDocument functions, it returns something like: ÐÐ»ÐµÐºÑ Ðœ I've tried setting DOMDocument encoding to different values (UTF-8, ISO-8859-1), using mb_convert_encoding, iconv and utf8_encode but without success. How can I get "????? ?" instead of "ÐÐ»ÐµÐºÑ Ðœ" ? EDIT: The input is coming from a page loaded with curl. When I output the page content to my browser, the characters are displayed correctly (so I doubt the input is the problem).

• Java App Engine - ranked counter

  - by Richard

  I understand the sharded counter, here: http://code.google.com/appengine/articles/sharding_counters.html The problem is that a simple counter will not work in my application. I am sorting my entities by a particular variable so I am returned not so much a count, but more of a rank. My current method is: SELECT COUNT(this) FROM Entity.class WHERE value <= ? Result + 1 is then the rank of the parameter in relation to the value variable in the persistent Entity objects. The limitation of this is the highest rank being returned is 1001 because count() can give a maximum of 1000. The reason I cannot store the rank on the Entity object is that the ranks are updated very often, and re-setting this rank variable would be much too costly. Any ideas on the best way to accomplish this?

• Doctrine lazy loading classes takes 100 ms?!

• What did I lose when I upgraded?

  - by Richard

  I upgraded my work box from Vista64 to Win7-64 by doing a format and reinstall. I kept backups of the project done in MS Visual Studio 2008 (Team). But now it won't compile. I am getting errors generated on lines in the MS created header files like "'_In_' not defined" etc. I know it is because I lost some compiler setting/directive. I was sure that the compiler settings would be in the project file; now I see that things like the include file directories, LIB files, etc. are not. [FYI: The project is a VB.NET GUI with VC++ DLL talking to a PIC24 micro over USB.] How do I most efficiently get my project back on the road to execution?

• Is it proper to get and especially set Perl module's global variables directly?

  - by DVK

  I was wondering what the best practice in Perl is regarding getting - or, more importantly, setting - a global variable of some module by directly accessing $Module::varName in case the module didn't provide getter/setter method for it. The reason it smells bad to me is the fact that it sort of circumvents encapsulation. Just because I can do it in Perl, I'm not entirely certain I should (assuming there actually is an alternative such as adding a getter/setter to the module). I'm asking this because I'm about to request an addition of a getter/setter for a global variable in one of the core Perl modules, and I would like to avoid it soundly and unanimously rejected on the grounds of "Why the heck do you need one when you can access the variable in the package directly?" - in case doing the latter is actually considered perfectly OK by the community.
