  • Connection Strings between Web Application and SQL Server

    - by Raven Dreamer
    Greetings. I'm writing a web application that is supposed to connect to a SQL Server database; the connection is formed from the following database string: <add key="DatabaseConnectionString" value="server=DEVPC1\SQLEXPRESS;uid=USERID;pwd=PASSWORD;database=DATABASE"/> However, whenever I try and run the web application, I get a connection error, specifically: An error occurred attempting this login: Login failed for user 'USERID'. Any suggestions on how to go about debugging this? I'm not really familiar with SQL, so any suggestions would be greatly appreciated.

  • Bluetooth server application accepting connections from mobile devices

    - by Bruno Reis
    Hello, I'd like to develop a desktop application (on Windows, and preferably on .NET) that accepts bluetooth connections from mobile devices, that would then send commands to this application. I've never worked with bluetooth before. I've looked for open-source examples of such applications, but I had no luck. I've actually found on Microsoft a managed (.NET) wrapper for the bluetooth stack on Windows CE, but wasn't able to use it on my Windows 7. Do you know of any good texts discussing this topic? Any other source of information on the subject? Where should I start? Thanks.

    When developing for android what are the benefits of using tabs to hold views or hold separate activities. I've read that both ways are better, but can't seem to find any good resources suggesting why or when to use each method.

  • Any tips on reducing wxWidgets application code size?

    - by Billy ONeal
    I have written a minimal wxWidgets application: stdafx.h #define wxNO_REGEX_LIB #define wxNO_XML_LIB #define wxNO_NET_LIB #define wxNO_EXPAT_LIB #define wxNO_JPEG_LIB #define wxNO_PNG_LIB #define wxNO_TIFF_LIB #define wxNO_ZLIB_LIB #define wxNO_ADV_LIB #define wxNO_HTML_LIB #define wxNO_GL_LIB #define wxNO_QA_LIB #define wxNO_XRC_LIB #define wxNO_AUI_LIB #define wxNO_PROPGRID_LIB #define wxNO_RIBBON_LIB #define wxNO_RICHTEXT_LIB #define wxNO_MEDIA_LIB #define wxNO_STC_LIB #include <wx/wxprec.h> Minimal.cpp #include "stdafx.h" #include <memory> #include <wx/wx.h> class Minimal : public wxApp { public: virtual bool OnInit(); }; IMPLEMENT_APP(Minimal) DECLARE_APP(Minimal) class MinimalFrame : public wxFrame { DECLARE_EVENT_TABLE() public: MinimalFrame(const wxString& title); void OnQuit(wxCommandEvent& e); void OnAbout(wxCommandEvent& e); }; BEGIN_EVENT_TABLE(MinimalFrame, wxFrame) EVT_MENU(wxID_ABOUT, MinimalFrame::OnAbout) EVT_MENU(wxID_EXIT, MinimalFrame::OnQuit) END_EVENT_TABLE() MinimalFrame::MinimalFrame(const wxString& title) : wxFrame(0, wxID_ANY, title) { std::auto_ptr<wxMenu> fileMenu(new wxMenu); fileMenu->Append(wxID_EXIT, L"E&xit\tAlt-X", L"Terminate the Minimal Example."); std::auto_ptr<wxMenu> helpMenu(new wxMenu); helpMenu->Append(wxID_ABOUT, L"&About\tF1", L"Show the about dialog box."); std::auto_ptr<wxMenuBar> bar(new wxMenuBar); bar->Append(fileMenu.get(), L"&File"); fileMenu.release(); bar->Append(helpMenu.get(), L"&Help"); helpMenu.release(); SetMenuBar(bar.get()); bar.release(); CreateStatusBar(2); SetStatusText(L"Welcome to wxWidgets!"); } void MinimalFrame::OnAbout(wxCommandEvent& e) { wxMessageBox(L"Some text about me!", L"About", wxOK, this); } void MinimalFrame::OnQuit(wxCommandEvent& e) { Close(); } bool Minimal::OnInit() { std::auto_ptr<MinimalFrame> mainFrame( new MinimalFrame(L"Minimal wxWidgets Application")); mainFrame->Show(); mainFrame.release(); return true; } This minimal program weighs in at 2.4MB! (Executable compression drops this to half a MB or so but that's still HUGE!) (I must statically link because this application needs to be single-binary-xcopy-deployed, so both the C runtime and wxWidgets itself are set for static linking) Any tips on cutting this down? (I'm using Microsoft Visual Studio 2010)

    - by Pentium10
    I have an Android application that connects to Facebook to request authorization of an Application. I use the following setting in the WebView, but once the view is loaded, I can't type in login details. What I am missing? WebView webview; webview = (WebView) findViewById(R.id.facebookview); webview.getSettings().setJavaScriptEnabled(true); webview.setWebViewClient(new FacebookWebViewClient()); webview .loadUrl("http://www.connect.facebook.com/login.php?return_session=1&nochrome=1&fbconnect=1&extern=2&connect_display=popup&api_key=" + FConnect.API_KEY + "&v=1.0&next=" + FConnect.SUCCESS_URL + "%3Ffb_login%26fname%3D_opener&cancel_url=" + FConnect.CANCEL_URL + "%23fname%3D_opener%26%257B%2522t%2522%253A3%252C%2522h%2522%253A%2522fbCancelLogin%2522%252C%2522sid%2522%253A%25220.741%2522%257D&channel_url=" + FConnect.XD_RECEIVER);

  • SVG drawing application with vector export

    - by Bram Jetten
    I want to create a drawing application where I can place text and images on a canvas. Those elements also need to be interactively manipulated. Eventually the resulting canvas has to be exported to a vector based PDF. An excellent contender for this functionality would be SVG. However, this application also needs to be crossbrowser compatible. I've been browsing around for some time now and have seen a couple of solutions available. I found among others RaphaelJS and Google's SVGWeb for working with SVG. Now for converting those SVG files to a PDF I'm not sure if for instance Batik will offer me what I am looking for. Also, how would bitmap images be handled when converting the SVG to PDF?

  • Disable a style in VCL application

    - by Martin
    I am adding the a VCL style into my application but am also giving the users an option to turn this off but I cannot figure out how to do this globally at runtime. Setting "TStyleManager.AutoDiscoverStyleResources := false" almost works but it pops up with an error message saying "Style {style set} not found" but after dismissing the message does exactly what I want. This code I would expect to work but does not... if (not ParamObj.UseDarkStyle) then begin //TStyleManager.AutoDiscoverStyleResources := false; TStyleManager.SetStyle(TStyleManager.SystemStyle); end; I also tried (originally) TStyleManager.TrySetStyle('Windows'); but this also does not work. I have tried this both sides of "Application.Initialize;" with no difference What am I missing? Thanks in advance, Martin

  • Improving the efficiency of Kinect for Windows DTWGestureRecognition Application

    - by Ray
    Currently I am using the DTWGestureRecognition open source tool for Kinect SDK v1.5. I have recorded a few gestures and use them to navigate through Windows 7. I also have implemented voice control for simple things such as opening PowerPoint, Chrome, etc. My main issue is that the application uses quite a bit of my CPU power which causes it to become slow. During gestures and voice commands, the CPU usage sometimes spikes to 80-90%, which causes the application to be unresponsive for a few seconds. I am running it on a 64 bit Windows 7 machine with an i5 processor and 8 GB of RAM. I was wondering if anyone with any experience using this tool or Kinect in general has made it more efficient and less performance hogging. Right now I removed sections which display the RGB video and the Depth video but even doing that did not make a big impact. Any help is appreciated, thanks!

  • Problems with Tomcat server and JSP web application

    - by CitadelCSCadet
    I am running a JSP/Servlet Web application and out of nowhere we experienced some random problems that don't make any sense. I checked the catalina.out file to check the log files, and I noticed it contained some of the following messages SEVERE: Error starting static Resources java.lang.IllegalArgumentException: Invalid or unreadable WAR file : error in opening zip file INFO: validateJarFile(/home/weremo/appservers/ apache-tomcat-6.0.26/webapps /WMA/WEB-INF/lib/ servlet-api.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class I am aware of what this message means, but am in the dark as to what could have caused it, or what effects it could have on the application.

  • memory of drawables, is it better to have resources inside APK, outside APK or is it the same for me

    - by Daniel Benedykt
    Hi I have an application that draws a lot of graphics and change them. Since I have many graphics, I thought of having the images outside the APK, downloaded from the internet as needed, and saved on the files application folder. But I started to get outOfMemory exceptions. The question is: Does android handle memory different if I load a graphic from APK than if I load it from 'disk'? code using APK: topView.setBackgroundResource(R.drawable.bg); code if image is outside APK: Drawable d = Drawable.createFromPath(pathName); topView.setBackgroundDrawable(d); Thanks Daniel

  • asp.net application install folder

    - by Maximilian Csuk
    Disclaimer: this is not a question about how to install asp.net or an application using it! Hi! I am pretty sure many of you have once installed some kind of forum, blog or CMS (mostly PHP powered applications). All of these contain a folder mostly named "install" where (after you copied the files to the webserver) point your browser to to complete the installation by entering for example database information (servername, username, password, ...). After that, most applications suggest that you delete this folder or at least change the permissions so nobody from the outside can access it anymore. Now to my question: how would you go about that in the asp.net world? I don't really like the "install folder"-approach and I thought there might be a different mechanism for .net/IIS. The person installing my application should be able to enter his database information as painless as possible, which should ultimatively be stored in the web.config file. If it makes a difference, I am using asp.net MVC. Thanks for your help!

  • JAAS tutorial - how to force application to run with policy

    - by wuntee
    I just went through this tutorial: http://java.sun.com/docs/books/tutorial/security/tour2/index.html And was curios about the basic concept of JAAS... If every applcation needs to be run with the '-Djava.security.manager -Djava.security.policy=...' flags, what is enforcing security? Is it up to the end user to know when any Java application is being run, and modify the executable/script/whatever to include those flags? Or, how does a developer enforce that an application is run with the security manager enabled? The whole concept doesnt seem very functional to me - as it is by default not enabled... Am I missing something?

  • Using file-path to images stored within the Application Settings

    - by Bill
    I am trying to develop an application that uses a number of images that are stored in a seperate remote file location. The file-paths to the UI elements are stored within the Application Settings. Although I understand how to access and use the file-path from Settings in C# (Properties.Settings.Default.pathToGridImages + "OK.png"), I am at a loss to figure out how to utilize the Settings paths in WPF, and can only seem to access the file if I include the file-path, such as: <Grid.Background> <ImageBrush ImageSource="C:\Skins\bottomfill.png" TileMode="Tile" /> </Grid.Background> I would have thought that concatenating "Properties.Settings.Default.pathToGridImages" with "bottomfill.png" in WPF could be done much like it can be done in C#. Can anyone please point me in the right direction?

  • Easiest way to export longitude and latitude data stored in a SQLite database to a file so it can be

    - by LordSnoutimus
    Hello, I have created an application that records a series of longitude and latitude values in a SQLite database and display them as a coloured track on a MapActivity. I now want to be able to export this data somehow (preferably to a file) so a user can upload the values to a website showing a Google Map API. My question is: what would be the quickest way to export the data (and in what file format: GPX, XML, CSV) to the SD card located on the Android device. Many thanks.

  • Flex4 Application state in a custom component

    - by itarato
    Hi, I'm porting my Flex3 app to Flex4 (FlashBuilder4). I get the whole new state concept, except one thing. In a custom component (separate mxml file) I'm using the main level Application's state. In Flex3 it was: <mx:State name="only_view_mode"> <mx:RemoveChild target="{myComponent.button1}" /> </mx:State> In Flex4 it should be something like that: <mx:State name="only_view_mode" /> and <mx:LinkButton id="button1" excludeFrom="???" /> My question is: how can I access to an Application state from a component? I checked the official reference (http://www.adobe.com/go/learn_flex4_alldocumentation_en) and Google of course but without any success. Thanks in advance

  • How to move from untyped DataSets to POCO\LINQ2SQL in legacy application

    - by artvolk
    Good day! I've a legacy application where data access layer consists of classes where queries are done using SqlConnection/SqlCommand and results are passed to upper layers wrapped in untyped DataSets/DataTable. Now I'm working on integrating this application into newer one where written in ASP.NET MVC 2 where LINQ2SQL is used for data access. I don't want to rewrite fancy logic of generating complex queries that are passed to SqlConnection/SqlCommand in LINQ2SQL (and don't have permission to do this), but I'd like to have result of these queries as strong-typed objects collection instead of untyped DataSets/DataTable. The basic idea is to wrap old data access code in a nice-looking from ASP.NET MVC "Model". What is the fast\easy way of doing this?
