  • Cannot manage to have the main form to show scrollbars if bigger

    - by Philippe Watel
    Hi everyone I have developped an app on 22inch monitor at its max resolution when I run this on a laptop with a different ratio and a smaller resolution well the form is too big - to be expected but no scroll bar appear automaticaly to see the whole thing if needed I have tempered with all options but could not figure it out I have tried autoscroll of course but nothing I am sure it is not so difficult but I am stuck So if anyone could indicate me what properties to change I'll be most greatful or even better some easy strategy or components (even paying) to achieve a better screen resolution independance but the scrollbar would be great to start with Thanks & Regards Philippe Watel

  • ApiChange Is Released!

    - by Alois Kraus
    I have been working on little tool to simplify my life and perhaps yours as developer as well. It is basically a command line tool that allows you to execute queries on your compiled .NET code base. The main purpose is to find out how big the impact of an api change would be if you changed this or that.  Now you can do high level operations like Diff public types for breaking changes. Who uses a method? Who uses a type? Who uses implements an interface? Who references me? What format has the binary  (32/64, Managed C++, Pure IL, Unmanaged)? Search for all event subscribers and unsubscribers. A unique feature is to check for event subscription imbalances. Forgotten event subscriptions are the 90% cause of managed memory leaks. It is done at a per class level. If one class does subscribe to one event more often than it does unsubscribe it is treated as possible event subscription imbalance. Another unique ability is to search for users of string literals which allows you to track users of a string constant which is not possible otherwise. For incremental builds the ShowRebuildTargets command can be used to identify the dependant targets that need a rebuild after you did compile one assembly. It has some heuristics in place to determine the impact of breaking changes and finds out which targets need to be recompiled as well. It has a ton of other features and a an API to access these things programmatically so you can build upon these simple queries create even better tools. Perhaps we get a Visual Studio plug in? You can download it from CodePlex here. It works via XCopy deployment. Simply let it run and check the command line help out. The best feature in my opinion is that the output of nearly all commands can be piped to Excel for further analysis. Since it does read also the pdbs it can show you the source file name and line number as well for all matches. The following picture shows the output of a –WhousesType query. The following command checks where type from BaseLibraryV1.dll are used inside DependantLibV1.dll. All matches are printed out with the reason and matching item along with file and line number. There is even a hyper link to the match which will open Visual Studio. ApiChange -whousestype "*" BaseLibraryV1.dll -in DependantLibV1.dll –excel The "*” is the actual query which means all types. The syntax is the same like in C# just that placeholders are allowed ;-). More info's can be found at the Codeplex Documentation.     The tool was developed in a TDD style manner which means that it is heavily tested and already used by a quite large user base inside the company I do work for. Luckily for you I got the permission to make it public so you take advantage of it. It is fully instrumented with tracing. If you find bugs simply add the –trace command line switch to find out what is failing and send me the output. How is it done? Your first guess might be that it uses reflection. Wrong. It is based on Mono Cecil a free IL parser with a fantastic API to access all internals of a managed assembly. The speed is awesome and to make it even faster I did make the tool heavily multi threaded. The query above did execute in 1.8s with the Excel output. On a rather slow machine I can analyze over 1500 assemblies in less than 40s with a very low memory consumption. The true power of Mono Cecil is that I can load an assembly like any other data file. I have no problems unloading a file but if I would have used reflection I would need to unload a whole AppDomain just to get rid of one assembly in my memory. Just to give you a glimpse how ApiChange.Api.dll can be used I show you one of the unit tests:           public void Can_Find_GenericMethodInvocations_With_Type_Parameters()         { // 1. Create an aggregator to collect our matches             UsageQueryAggregator agg = new UsageQueryAggregator();   // 2. This is the type we want to search for. Load it via the type query             var decimalType = TypeQuery.GetTypeByName(TestConstants.MscorlibAssembly, "System.Decimal");   // 3. register the type query which searches for uses of the Decimal type             new WhoUsesType(agg, decimalType);   // 4. Search for all users of the Decimal type in the DependandLibV1Assembly             agg.Analyze(TestConstants.DependandLibV1Assembly);   // Extract matches and assert             Assert.AreEqual(2, agg.MethodMatches.Count, "Method match count");             Assert.AreEqual("UseGenericMethod", agg.MethodMatches[0].Match.Name);             Assert.AreEqual("UseGenericMethod", agg.MethodMatches[1].Match.Name);         } Many thanks go from here to Jb Evian for the creation of Mono.Cecil. Without this fantastic piece of code it would have been much much harder. There are other options around like the Common Compiler Infrastructure  Metadata Api which should do the same thing but it was not a real option since the Microsoft reader did fail on even simple assemblies (at least in September 2009 this was the case). Besides this I found the CCI Apis much harder to use. The only real competitor was Reflector which does support many things but does not let me access his cool high level analyze commands. So I decided to dig into the IL specs and as a result you can query your compiled binaries from the command line or programmatically. The best thing is you try it out for yourself and give me some feedback what you miss. If you want to contribute or have a cool idea what should be added drop me a mail at A Kraus1@___No [email protected]. There is much more inside the tool I did not talk about it (yet).

    Hello, I'm working on a soundboard, however I've got a problem when it come to drag the finger over the screen to play the sounds for the buttons I drag the finger over. Button Button3 = (Button)findViewById(R.id.button03); Button3.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if(event.getAction() == MotionEvent.ACTION_DOWN){ mp.playSound(3); } return false; } }); Do anyone know how I can detect when a finger enter a button and not click the button? THanks :)

  • Jquery Widget Performance

    - by jamie-wilson
    I am working on an interface which involves ALOT of javascript. There is a calendar and blocks drawn on the calendar. The calendar is a jQuery widget, which works beautifully. The blocks drawn on top are also jQuery widgets. While it works - I am wondering, every time I create another block, is the widget fully duplicating, or is it referencing the widget? If I end up with 200 blocks on the screen, do I have 200 copies of the widget? Because if so i'm sure this will impact the performance quite heavily. Also it would determine whether I have functions inside the widget, or have them external to the widget looking in if that makes sense. Just putting some feelers out there for thoughts. I couldn't find anything by searching online.

  • Techniques to avoid DeadlineExceededException in GAE/J?

    - by Tahir Akram
    I am developing an Twitter4J web application in Google App Engine/Java. I need to show two lists. One is Twitter friends and other is followers. With photo and screen name. It is working fine for people who have 20-30 followers and friends. But it gave me DeadlineExceededException when I try a user who has 150+ followers and friends. GAE throws this exception if web request take time more than 30 seconds. So what techniques I can adopt to avoid this exception. Should I generate two AJAX calls for each of my list. After page loads. So that every call will have its own 30 secs limit? Or what else you think? I am gone make it. Please help.

  • How can I avoid floating the same content twice?

    - by Randall Bohn
    My Kynetx app uses float_html() to put up a box full of content. rule float_box { select when pageview ".*" pre { content = << <div id='messagebox'> <h3>Floating Message Box</h3> <ul id='my_list'></ul> </div> >>; } float_html("absolute","top:25px","right:20px",content); } rule fill_box { select when pageview ".*" foreach ["alpha","bravo","charlie"] setting (list_item) append("#my_list", "<li>#{list_item}</li>"); } The app (a421x27) is used from a bookmarklet. If you click the bookmarklet twice on the same page you get double content. Is there any way to detect that the box is already on the screen and reuse it?

  • Interface Builder "Simulate Interface" not working

    - by bpapa
    I am using Interface Builder to play around with some ideas. I never noticed that there is a "Simulate Interface" feature which apparently will render the nib in the iPhone simulator. So, I created a view, put one component in there (a Segmented Control), saved it, selected "Simulate Interface", the simulator launched but... nothing rendered in the simulator. Just a black screen. I thought maybe my nib wasn't complete enough, so I've tried it with all of my old nibs and I'm having the same problem with all of them. None of them render in the simulator at all. Is there some trick that I'm missing?

  • Compatibility issues with <a> and calling a function(); across different web browsers

    - by Matthew
    Hi, I am new to javascript. I wrote the following function rollDice() to produce 5 random numbers and display them. I use an anchor with click event to call the function. Problem is, in Chrome it won't display, works fine in IE, in firefox the 5 values display and then the original page w/anchor appears! I am suspicious that my script tag is too general but I am really lost. Also if there is a display function that doesn't clear the screen first that would be great. diceArray = new Array(5) function rollDice() { var i; for(i=0; i<5; i++) { diceArray[i]=Math.round(Math.random() * 6) % 6 + 1; document.write(diceArray[i]); } } when I click should display 5 rand variables

  • ASP.NET SetAuthCookie Impersonation Help

    - by rlb.usa
    Hello SO, I'm trying to do user impersonation for a web application we have. The user selects the user they'd like to emulate/impersonate and then clicks the button which fires this: protected void uxImpersonate_Click(object sender, EventArgs e) { ... FormsAuthentication.SetAuthCookie(uxUserToEmulate.SelectedValue, false); Response.Redirect("Impersonation.aspx"); //reload page manually } We have a dev - test - production server environment and on two servers this works just fine, but on another one, in all browsers, it kicks me to the login screen. What's going on and how can I fix it? We're on ASP.NET 2.0, and I'm using http://stackoverflow.com/questions/549016/user-impersonation-with-asp-net-forms-authentication as a guide. UPDATE: It appears that the user actually is impersonated successfully but is loosing their Role as admin (only Admin Role's can access this impersonation page).

  • Automating an application

    - by dacman
    I've always wondered the best way to automate use of a GUI in windows. When I was about 15, I wrote a little application that used some simple windows api functions to automatically click on certain locations on the screen based on a script. This could be used to automate GUI apps, but surely it's not the best way. So, my question is: What's the best way to automate use of a GUI in windows? Are there certain windows API functions that would be beneficial? If the program were to crash, how could you detect that? Thanks!

  • svn reintegrate a branch with externals fails

    - by dnndeveloper
    using svn 1.6.6 with tortoisesvn 1.6.6 what I am doing: 1) Apply external properties to a folder in the trunk (both single file and folder external, externals are binary files) 2) Create a branch from the trunk and update the entire project 3) Modify a file on the branch and commit the changes, then update the entire project. 4) Merge - "Reintegrate a branch" when I get to the last screen I click "test merge" and get this error: Error: Cannot reintegrate into mixed-revision working copy; try updating first I update the entire project and still the same error. other observations: If I "Merge a range of revisions" everything works fine. If I remove the externals everything works fine using either "Merge a range of revisions" or "Reintegrate a branch" Anyone else having this issue?

  • Pygame program that can get keyboard input with caps

    - by None
    I have a Pygame program that needs text input. The way it does this is to get keyboard input and when a key is pressed it renders that key so it is added to the screen. Essentially it acts like a text field. The problem is, when you hold shift it doesn't do anything. I relize this is because the program ignores shift input and instead writes the text if it's number is under 128. I have thought of setting a variable when shift is pressed then capitalizing if it was true, but string capitalization only woks on letters, not things like numbers or semicolons. Is there maybe a number I can add to the ascii number typed to modify it if shift is pressed, or something else?

  • Position a UIView at the middle of a UITableView with CGRectZero frame

    - by Thomas Joulin
    Hi, I have a UITableViewController view a UITableView that I alloc/init with a frame of CGRectZero : self.tableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStyleGrouped]; I want to add a view at the middle of the tableView (a loading view with a UIActivityIndicatorView and a UILabel), but I don't know how to position it, since I don't know the tableView frame. x = (self.tableview.frame.size.width - loadingView.frame.size.width) / 2.0; y = (self.tableview.frame.size.height - loadingView.frame.size.height) / 2.0; [loadingView setCenter:CGPointMake(x, y)]; I did init my tableView with CGRectZero frame so it can take the whole place available on screen (which it did), but I thought its frame would update or something. Any ideas ? Thanks !

  • I have some questions about building an AIR app for use with a connected projector.

    - by knuckfubuck
    For an app I'm working on, I'd like to have a control panel window and a video output window to use for projecting video with an attached projector. I have built many Flash applications but this will be my first time using AIR so I have some questions. Is it possible to have two seperate windows as part of one AIR application? Can one of the windows (the video output) be in full-screen mode while the other window stays normal? How does AIR do with playing local video? Will there be crashes or choppy playback? Is there a better language option for what I'm trying to accomplish?

  • unable to get into windows 7 or ubuntu after system file back on a dual boot system

    - by John Jiang
    I installed ubuntu on my dell xps 9000 which originally has a window 7 installed. So after I did system file back up as told by windows 7 and restarted my computer, I received the following message right after restarting in the black screen: roughly like this: ubuntu grub error, " " symbol cannot be found. I was wondering how I can get access into windows 7 and uninstall ubuntu all together. I actually had the same booting problem after system backup before and the solution was to install two extra ubuntus but I'd prefer not to do that. I'd highly appreciate any help!

  • Polling versus socket servers for online Flash games

    - by justin
    Hi, I want to make an online flash game, it will have social features but the gameplay will be primarily single-player. For example, no two players will appear on the screen at once, the social interaction will be through asynchronous messages, there won't be real-time chat or anything. Much of the logic would happen in the client, the server would validate the client logic, but it wouldn't need to be totally synchronous, which is why I'm thinking polling might be satisfactory. I have read in many places that socket servers can be more efficient than using polling for online games, but is that mainly a consideration for games that are more multi-player with more mult-player interactions than the game I have descriebed? If many users are playing online at the same time, but each playing a relatively isolated game, and not interacting to in real-time with each players, could polling be okay, or would using sockets be advisable no matter what if you have an online game that you envision many people playing at the same time? Thanks!

  • Programmatically determine DPI via the browser?

    - by Brandon Pelfrey
    Hi all. I would like to programmaticaly determine the DPI of a user's display in order to show a web page at a precise number of units (centimeters/inches). I know it a weird request: it's for a visualization research project and it's kind of a control. We currently do it by having the user place a credit card to the screen and match a resizable div (via Mootools) to the real credit card, and voila we can get the DPI and display the page correctly. Can anyone think of a programmatic way to do this?

  • pyplot: really slow creating heatmaps

    - by cvondrick
    I have a loop that executes the body about 200 times. In each loop iteration, it does a sophisticated calculation, and then as debugging, I wish to produce a heatmap of a NxM matrix. But, generating this heatmap is unbearably slow and significantly slow downs an already slow algorithm. My code is along the lines: import numpy import matplotlib.pyplot as plt for i in range(200): matrix = complex_calculation() plt.set_cmap("gray") plt.imshow(matrix) plt.savefig("frame{0}.png".format(i)) The matrix, from numpy, is not huge --- 300 x 600 of doubles. Even if I do not save the figure and instead update an on-screen plot, it's even slower. Surely I must be abusing pyplot. (Matlab can do this, no problem.) How do I speed this up?

  • How do you do a foursquare style uitableview refresh?

    - by nickthedude
    If you haven't seen their implementation Of the refresh of a tableview it is extremely slick. I was surprised to see no search results asking for this to be explained so I figured ask it myself. If you haven't seen it, it basically adds a subviews to the uitableview above the header to the blank part of the screen when you pull a uitableview view down farther than it has data to display. Sorry if that doesn't make sense but just download the app and you will immediately want to do it too. Just wondering how they did it?

  • Scroll up/down while selecting multi-page block of text in Vim through putty

    - by shan23
    I'm using vim 6.3.81 on a xterm through putty. When I use set mouse=a , I can scroll through the file , but not select text. When mouse is disabled using set mouse=, I can select text with mouse (automatically copied to a buffer) , but if the text block is over one page long , I can't scroll up/down (and have to select text one screen at a time) !! Is there any way to have the best of both - while selecting text with mouse , if i reach the end of page , it automatically scrolls up/down depending on whether i've reached top/bottom of page and allows me to select text from the next page as well ? I know vim is powerful/flexible enough to do what I want - I just don't know how !! Can anyone help ?

    Hi, In my iPhone application I need to show a video image in UITableView. Each tableViewCell have video and some labels. I used the MPMoviePlayerController for showing video in full screen when the cell is selected. But, I am getting error that MPMoviePlayerController class is not there. I tried using UIWebView. But, I could not make it. How can I play a video, when the cell is selected. Some say that videos do not play in simulator. They only play when we test in device. Is it right ? Please help me with the solution. Thank You.
