  • "Attach to process" missing from Delphi 7's Run menu

    - by glob
    I have to resurrect an ancient Delphi 7 application, which means I have to use the D7 IDE. Upgrading the project to a more recent version of Delphi unfortunately isn't an option. My new D7 installation's Run menu is missing Attach to Process. Aside from the missing menu item, the debugger works fine (I can debug normal Delphi executables started with Run). I know D7 supported this feature (it's in the help file), so does anyone have any idea what I've missed? The installation is Delphi 7 Enterprise (Version 7.0 Build 4.453). Current Run menuitems: Run Parameters... - Step Over Trace Into Trace to next Source line Run to Cursor Run Until Return Show Execution Point Program Pause Program Reset - Evaluate/Modify Add Watch Add Breakpoint

  • what's an option strict and explicit?

    - by Ygam
    I saw this post: "Typos… Just use option strict and explicit please.. during one software development project, which I was on as a consultant, they were getting ridiculous amounts of errors everywhere… turned out the developer couldn’t spell and would declare variables with incorrect spelling.. no big deal, until you use the correct spelling when you’re assigning a value to it… and you had option explicit off. Ouch to them…" what is an option strict and explicit anyway? I have googled it up but can't get the idea (because mostly it's Visual Basic, I'm doing PHP)

  • macdeployqt and third party libraries

    - by user338170
    I've got an application project that depends on a couple of shared libraries that I have created myself. According to the Qt 4.6 documentation "Deploying an Application on Mac OSX": Note: If you want a 3rd party library to be included in your application bundle, then you must add an excplicit lib entry for that library to your application's .pro file. Otherwise, the macdeployqt tool will not copy the 3rd party .dylib into the bundle. I have added lib entries to my application's .pro file but the libraries that I have written do not get copied into the bundle when I execute macdeployqt. I have the following in my .pro file: LIBS += -L../Libraries -lMyLib Everything builds okay, its just when I try to run from the bundle that I run into problems i.e. "image not found" errors. Is there a bug in macdeployqt or do I have to something more to my .pro file?

  • Accessing functions in a parent controller

    - by meridimus
    I have made a ViewController in XCode for an iPhone project I'm working on, but I have a question about nested ViewControllers and what the best way to access a parents ViewController functions? Essentially, at the moment I have a SwitchViewController with MenuViewController (nested) and GameViewController (nested, which renders OpenGL ES). At the moment, I have animated view switching controlled in the SwitchViewController which works. But I want to call it after a player has selected the level from the MenuViewController and run the appropriate level in GameViewController. Not rocket science, I know. What's the best way to call parent functions?

  • Architectural decision : QT or Eclipse Platform ?

    - by umanga
    We are in the process of designing a tool to be used with HDEM(High Definition Electron Microscope).We get stacks of 2D images from HDEM and first step is 'detecting borders' on the sections.After detecting edges of 2D slices ,next step is construct the 3D model using these 2D slices. This 'border detecting' algorithm(s) is/are implemented by one of professor and he has used and suggests to use C.(to gain high performance and probably will parallelise in future) We have to develop comprehensive UI ,3D viewer ,2D editor...etc and use this algorithm. Application should support usual features like project save/open.Undo,Redo...etc Our technology decisions are: A) Build entire platform from the scratch using QT. B) Use Eclipse Platform Our concerns are, if we choose A) we can easily integrate the 'border detecting' algorithm(s) because the development environment is C/C++ But we have to implement the basic features from the scratch. If we choose B) we get basic features from the Eclipse platform , but integrating C libraries going to be a tedious task. Any suggestions on this?

  • C# - How can i open a second winform asynchronously but still behave as a child to the parent form?

    - by Gary Willoughby
    I am creating an application and i would like to implement a progress window that appears when a lengthy process is taking place. I've created a standard windows form project to which i've created my app using the default form. I've also created a new form to use as a progress window. The problem arises when i open the progress window (in a function) using: ProgressWindow.ShowDialog(); When this command is encountered, the focus is on the progress window and i assume it's now the window who's mainloop is being processed for events. The downside is it blocks the execution of my lengthy operation in the main form. If i open the progress window using: ProgressWindow.Show(); Then the window opens correctly and now doesn't block the execution of the main form but it doesn't act as a child (modal) window should, i.e. allows the main form to be selected, is not centered on the parent, etc.. Any ideas how i can open a new window but continue processing in the main form?

  • In Elixir or SQLAlchemy, is there a way to also store a comment for a/each field in my entities?

    - by kchau
    Our project is basically a web interface to several systems of record. We have many tables mapped, and the names of each column aren't as well named and intuitive as we'd like... The users would like to know what data fields are available (i.e. what's been mapped from the database). But, it's pointless to just give them column names like: USER_REF1, USER_REF2, etc. So, I was wondering, is there a way to provide a comment in the declaration of my field? E.g. class SegregationCode(Entity): using_options(tablename="SEGREGATION_CODES") segCode = Field(String(20), colname="CODE", ... primary_key=True) #Have a comment attr too? If not, any suggestions?

  • C# String Resource Values as Enum String Part values?

    - by JL
    Using VS2010 and .net V4.0 I would like to achieve the following: I already have 2 resource files in my project for 2 languages - English and Czech. I must say Resource Management in .net is excellent, I am suprised even to get code completion when implementing a String for example: string desc = Strings.ResourceManagerDesc This gets the string associated with the current culture of the thread. Now I am trying to create an Enum that can have the String portion of the Enum interpreted from the Strings resources. In the following way (This code DOES NOT WORK): public enum DownloadStatus { 1 = Strings.DownloadState_Complete, 2 = Strings.DownloadState_Failed, 3 = Strings.DownloadState_InProgress } This is a made up example, but you can see the point here. Since the above code won't work, is there a best practice way to achieve what I want?

  • Table with a lot of attributes

    - by Robert
    Hi, I'm planing to build some database project. One of the tables have a lot of attributes. My question is: What is better, to divide the the class into 2 separate tables or put all of them into one table. below is an example create table User { id, name, surname,... show_name, show_photos, ...) or create table User { id, name, surname,... ) create table UserPrivacy {usr_id, show_name, show_photos, ...) The performance i suppose is similar due to i can use index.

  • Kohana3 - Auth Module deleting User while he is logged in bug

    - by ahmet2106
    Hello Stackoverflow Users, Today I've tested the Kohana3, which has been changed a lot. I'm working so much with the Auth Module, and need this in my new Project also. Now I found a Bug, I think it is a bug, what can I do? Problem: After I'm deleting a user from the Database, who is at this Moment logged_in() in my Website, and he is refreshing the page, he will be logged_in() as the first user out of the PRAEFIX_users Table. Even if he is deleted. And 99% this is an Administrator. My function which is checking and redirecting if he is not logged_in(): if(!Auth::instance()->logged_in()) { $this->request->redirect( 'login' ); } How can i change my Check Login so, that if he is deleted, he will be redirected to login (/login/) ? Here the same Thread at Kohana Forums, but I hope and think, stackoverflow is a litte bit faster :)

  • Images not displayed in silverlight when app is run

    - by Sean
    I'm trying to display an image within a Silverlight application but the image does not display when the application is run. When creating the project within Visual Studio I chose the "Automatically generate a test page to host Silverlight at build time" option. Complete code as an example: <UserControl x:Class="SilverlightApplication3.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="300"> <StackPanel> <Image Source="http://www.beachtownpress.com/db5/00415/beachtownpress.com/_uimages/beach7.jpg" /> </StackPanel> </UserControl> The application appears perfectly within Visual Studio, but when I run the application, the image does not display. Any ideas?

  • How to serve a View as CSV in ASP.NET Web Forms

    - by ChessWhiz
    Hi, I have a MS SQL view that I want to make available as a CSV download in my ASPNET Web Forms app. I am using Entity Framework for other views and tables in the project. What's the best way to enable this download? I could add a HyperLink whose click handler iterates over the view, writes its CSV form to the disk, and then serves that file. However, I'd prefer not to write to the disk if it can be avoided, and that involves iteration code that may be avoided with some other solution. Any ideas?

  • How do you fix the Silverlight application shift that occurs in the Firefox browser?

    - by Roy
    Hi, Currently I have an Silverlight application that when run on Firefox browser (ver 3.6) the entire contents of the Silverlight application shifts a little, and also the scrollbars on both the bottom and the side appear when I first use it. This does not happen in IE 8. How can I fix this in Firefox so it doesn't happen? The project type I created was the "Silverlight 3 Application + Website" via Expression Blend 3. This the code I am using in my MainPage.xaml: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="StackoverflowExample.MainPage" Width="640" Height="480"> <Grid x:Name="LayoutRoot" Background="Green"> <Rectangle Fill="#FFBB2020" Stroke="Black" Margin="155,58,266,178"/> <Button Margin="199,180,302,236" Content="Button"/> </Grid> </UserControl>

  • Twitter Bootstrap Collapsible Navbar Duplicating

    - by sixeightzero
    I am working on a project using Twitter Bootstrap. One thing that I noticed is that my pages have duplicate navbars when they are defined as collapsible and the page is resized smaller.

  • How to register a model in django-tagging anywhere not in the applications?

    - by culebrón
    Is it possible to register a model in django-tagging not in tagging app, nor in my app? The standard way is to edit apps/myapp/models.py this way: from apps import tagging tagging.register(MyModel) I want to keep both applications without changes, for example, to be able to pull new versions and just replace them. So I tried putting this into project settings.py, in the end, but of course this fails. from apps.myapp.models import MyModel from apps import tagging tagging.register(MyModel) (This fails when importing MyModel.) Any other way?

  • UITextView like iPhone Notes application

    - by Mark
    I am trying to recreate the Notes application. So far I got the following: textView = [[UITextView alloc] initWithFrame:CGRectMake(25.0, 30.0, 295.0, 214.0)]; textView.delegate = self; textView.backgroundColor = [UIColor clearColor]; textView.font = [UIFont fontWithName:@"MarkerFelt-Thin" size:19.0]; [self.view addSubview:textView]; The thing I dont know is how they were able to put the date on top like a header (it is within the UIScrollView that is obvious). Also under every text there is a line where did that came from. Does someone have an idea or a sample project I can take a look at?

  • Why my custom CStatic derived control does not receive WM_SIZE message?

    - by Michael P
    Hello everyone! I'm currently developing a custom control that derives from CStatic MFC class (Smart Device C++ project). I have created the control class using VC++ MFC class wizard, selecting CStatic class as its base class. I have used Class View to add OnSize event handler for my control class (I have selected WM_SIZE message from messages list), and new OnSize method has been created by Visual Studio along with ON_WM_SIZE() statement between BEGIN_MESSAGE_MAP(...) and END_MESSAGE_MAP(). The problem is that my control does not receive WM_SIZE thus OnSize method is never called - I used MoveWindow to change size of my control - its size changes as I have seen on dialog window but WM_SIZE message is never being sent. When I send WM_SIZE through SendMessage or PostMessage function - the control OnSize method is called normally. What do I wrong? I've read MSDN docs about CStatic control and there is no information that WM_SIZE message is never sent to a static control window. Sorry for my bad English.

  • SQLite doesn't have booleans or date-times...but C# does

    - by DanM
    I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types. If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed in properties of type int? If yes, what are the implications? I'm envisioning a scenario where I need to write a whole second layer of classes with more specific data types and do a bunch of transformations and casts, but maybe it's not so bad. If you have any experience with this or a similar scenario, what are your "lessons learned"?

  • Programming against WSDL without access to actual webservice

    - by Frode Lillerud
    I'm going to use C# to read data from a few webservices. I've done that many times before, but those times I've had direct access to the webservices from my development machine. In this project I've just been sent a .wsdl file, and a couple of .xsd files for the webservice they have in their local intranet. I've seen that I can use "Add Web Reference", and point directly to the .wsdl file, so that a C# class is created. But how can I really test it? I'd like to return some dummy data that I can visualize while I develop. Any tips for this situation?

  • HPC (mainly on Java)

    - by Insectatorious
    I'm looking for some way of using the number-crunching ability of a GPU (with Java perhaps?) in addition to using the multiple cores that the target machine has. I will be working on implementing (at present) the A* Algorithm but in the future I hope to replace it with a Genetic Algorithm of sorts. I've looked at Project Fortress but as I'm building my GUI in JavaFX, I'd prefer not to stray too far from a JVM. Of course, should no feasible solution be available, I will migrate to the easiest solution to implement.

  • What first game did you program, and did it make you a better developer?

    - by thenonhacker
    What first game did you program? Name your game, the OS and language, and even a Website URL to get your game. Old DOS Games and Flash Games with ActionScript are allowed. Game kits are allowed, too. ...and did it make you a better developer? Programming games can be addicting, and it will bring out the best in us as we create our first game. What lessons did you learn form most? Algorithm and/or AI's? Graphics? User Interface? File Formats and Data Storage? Project and Time Management? Can you say that because you practiced programming by creating this game, you became more immersed with the programming language you used and helped you become a better developer?

  • How to set up source control in VS2010

    - by Jouke van der Maas
    Hi, I want to set up source control for my project, but it seems like I need a server for this. I've never done this before, and I couldn't find anything helpfull yet. Is there any way to host a server locally so Visual studio can use it? Or do you know any online (free) servers I can use? By the way, if source control is not actually what i should use for keeping track of changes in my files, please suggest a better option. Thanks in advance.

  • Numerical Pattern Matching

    - by Timothy Strimple
    A project I'm researching requires some numerical pattern matching. My searches haven't turned up many relevant hits since most results tend to be around text pattern matching. The idea is we'll have certain wave patterns we'll need to be watching for and trying to match incoming data vs the wave database we will be building. Here is and example of one of the wave patterns we'll need to be matching against. There is clearly a pattern there, but the peaks will not have the exact same values, but the overall shape of the wave iterations will be very similar. Does anyone have any advice on how to go about storing and later matching these patterns, and / or other search terms I can use to find more information on the subject of pattern matching? Thanks, Tim.

  • Data Access Layer in an ASP.NET website

    :) i have a DAL class file in my project, that my teacher sent me and explained to me but i did not really understand it. It has number of functions, and I understand only few of them, like with connecting to the database or creating a command object but there are 2 that I dont understand: public static DataTable GetTable(string str) { OleDbConnection con = DAL.GetConnection(); OleDbCommand cmd = DAL.GetCommand(con, str); DataTable dt = new DataTable(); OleDbDataAdapter adp = new OleDbDataAdapter(); adp.SelectCommand = cmd; adp.Fill(dt); return dt; } public static int ExecuteNonQuery(string str) { int num = -1; OleDbConnection con = DAL.GetConnection(); con.Open(); if (con.State == ConnectionState.Open) { OleDbCommand cmd = DAL.GetCommand(con, str); num = cmd.ExecuteNonQuery(); con.Close(); } return num; } thank you :)

  • How can I package sqlite with my Perl for Windows application?

    - by Paul Nathan
    I need to set up sqllite for Perl on a Windows box. However - Perl is probably being run over the network from a central server, and I do not know what modules will be available on initial running of my script. I can guarantee Perl 5.8+ (activestate) or Perl 5.10+ (strawberry). Therefore, I need to package sqlite & the associated Perl module(s) in the project directory itself. Having Goggled around, I don't see any immediate zipfile to do this.
