  • Should I use WPF or Windows Forms Application for my project in C#?

    - by RAJ K
    I am developing a Client-Server based application in which client application will access server database to store billing information. It will also have report generation facility. Windows Forms is good in document printing & I don't see such facility or controls in WPF. If I am wrong then please correct me. I want database security, which DB should I use, SQL Server, MySQL or Oracle. I would like to use free DB but security is my priority. Please suggest how I can implement a Client-Server architecture with multiple clients in C#? Thank you Geeks!!!

  • useful JMX metrics for monitoring WebSphere Application Server (and apps inside it)?

    - by Justin Grant
    When managing custom Java applications hosted inside WebSphere Application Server, what JMX metrics do you find most useful for monitoring performance, monitoring availability, and troubleshooting problems? And how do you prefer to slice and visualize those metrics (e.g. chart by top 10 hosts, graph by app, etc.). The more details I can get, the better, as I need to specify a standard set of reports which IT can offer to owners of applications hosted by IT, which those owners can customize but many won't bother. So I'll need to come up with a bunch of generally-applicable reports which most groups can use out-of-the-box. Obviously there's no one perfect answer to this question, so I'll accept the answer with the most comprehensive details and I'll be generous about upvoting any other useful answer. My question is WebSphere-specific, but I realize that most JMX metrics are equally applicable across any container, so feel free to give an answer for JBoss, Tomcat, WebLogic, etc.

  • How to run Rails 3 application on localhost/<my_port> ?

    - by Misha Moroshko
    To run Rails application on Windows I do: cd < app_dir rails server I see the following: => Booting WEBrick => Rails 3.0.1 application starting in development on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server [2011-01-12 20:32:07] INFO WEBrick 1.3.1 [2011-01-12 20:32:07] INFO ruby 1.9.2 (2010-08-18) [i386-mingw32] [2011-01-12 20:32:07] INFO WEBrick::HTTPServer#start: pid=5812 port=3000 Question 1 Why port 3000 is selected ? Where is it configured ? Question 2 How could I run 2 applications in parallel ? I guess I need to configure one of them to be on other port (like 3001). How should I do this ?

  • How can my application submit salesforce case with custom fields?

    - by Aaron
    I have an application that submits bugs for multiple customers to multiple destinations. I would like this application to include salesforce as a destination. I have web reference to the Enterprise WSDL and I am able to create cases for salesforce. This works great until I want to include user defined custom fields as part of the case. The custom fields are strongly typed with a __c prefix for my instance of salseforce. But I will not have the liberty of updating my web service with my customers instance of salesforce. How can I submit a salesforce case with custom fields that are not defined in the WSDL? Should I not be using the Enterprise WSDL?

  • What tool can I use to extract resources from a VB6 application?

    - by RichieACC
    One of my clients has an application that was written for them using VB6. They no longer have the original resources that were given to the developer. The developer has disappeared off the face of the earth. My challenge is to extract the resources from the executable and rebuild the application, adding new material to it. I've tried using Resource Hacker, but that only finds the icon. The exe is over 26MB, I can't see that the only resource embedded is the icon. Is there a way to extract this resource?

  • Which technology(s) / language(s) to write linux web application/service? [closed]

    - by Lee Tickett
    I am currently playing with some open source home automation software www.domotiga.nl The software is built in Gambas2 (a graphical programming language similar to visual basic). I am considering building something similar or porting domotiga to a server based application/service. The application would need a web front end and i will likely be developing in debian (arm). But i'm not sure if php or python are suitable for server based applications which need to be always running (collecting data etc) rather than just running when accessed. Which technology(s) / language(s) would you suggest i look into? I used to do a lot of Visual Basic, then VB.NET, now C# and have played with php a few years back- but don't really want this to sway the decision too much as i should be able to pickup whatever language if i decide to proceed.

  • When should one let an application crash because of an exception in Java (design issue)?

    - by JVerstry
    In most cases, it is possible to catch exceptions in Java, even unchecked ones. But, it is not necessarily possible to do something about it (for example out of memory). For other cases, the issue I am trying to solve is a design principle one. I am trying to set-up a design principle or a set of rules indicating when one should give up on an exceptional situation, even if it is detected in time. The objective is trying to not crash the application as much as possible. Has someone already brainstormed and communicated about this? I am looking for specific generic cases and possible solutions, or thumb-rules. UPDATE Suggestions so far: Stop running if data coherency can be compromised Stop running if data can be deleted Stop running if you can't do anything about it (Out of memory...) Stop running if key service is not available or becomes unavailable and cannot be restarted If application must be stopped, degrade as gracefully as possible Use rollbacks in db transactions Log as much relevant information as you can Notify the developers

  • How to change the app name in OSX menubar in a pure-Python application bundle?

    - by gyim
    I am trying to create a pure-Python application bundle for a wxPython app. I created the .app directory with the files described in Apple docs, with an Info.plist file etc. The only difference between a "normal" app and this bundle is that the entry point (CFBundleExecutable) is a script which starts with the following line: #!/usr/bin/env python2.5 Everything works fine except that the application name in the OSX menubar is still "Python" although I have set the CFBundleName in Info.plist (I copied the result of py2app, actually). The full Info.plist can be viewed here: http://tinyurl.com/32qgpjt How can I change this? I have read everywhere that the menubar name is only determined by CFBundleName. How is it possible that the Python interpreter can change this in runtime? Note: I was using py2app before, but the result was too large (50 MB instead of the current 100KB) and it was not even portable between Leopard and Snow Leopard... so it seems to be much easier to create a pure-Python app bundle "by hand" than transforming the output of py2app.

  • How to setup Apache 2.2 (prefork) with mod_fcgid to test a C++ application?

    - by skyeagle
    I have written my first fastcgi application (C/C++), and I need to test it to ensure that it is behaving the way I expect it to. I have searched for examples on setting up Apache 2.2. with mod_fcgid, but all of teh tutorials etc I have seen, relate to PHP, Python, Perl etc. Is anyone aware of a resource that shows how I may setup Apache to use mod_fcgid (NOT mod_fastcgi) to test my binary? If no online resource is available (I'd be surprised), then could someone please point out the steps required to do the testing?

  • How to make a Windows Mobile based WinForms .Net application easily changeable?

    - by Arthur
    I need to build a Win Mobile WinForms .Net application that once developed will be easy to morph or adjust to new user requirements quickly (including changes in GUI). The main objective is to minimize the development time (development to production roll-out effort). Also, a nice thing to have is to be able to test it in an automated way. The application must be able to: 1) Persist state (may use a local database); 2) Sync data across (via Radio or WiFi); 3) Exchange info with a desktop PC or a central server;

  • Can an application on the user's computer be started from a Firefox Extension?

    - by Saurabh Agarwal
    For example, can I start an instance of "Calculator.exe" on the user's computer (if it is available of course) upon some particular event in firefox, say clicking of a button? I thought of perhaps linking the extension to Python's subprocess method using XPCOM. But I was wondering whether there is an easier way. Additional information: I do not, at this point need to interact with the application upon its instantiation. Therefore I am looking for a way to open an application that's all. (Though, out of interest, if you have any pointers to interact with the same as well, that would be great) Thanks!

  • Dotfuscator from .NET 2.0

    - by vasek7
    Is there any chance to see Application Runs on Codeplex with .NET 2.0 application? I explored Dotfuscator is using web service url http://so-s.info/PreEmptive.Web.Services.Messaging/MessagingServiceV2.asmx. Is possible to track application run event manually? Something like add web service reference and call: Dotfuscator.MessageCache messages = new Dotfuscator.MessageCache(); messages.Business.CompanyId = new Guid("3E35F098-CE43-4F82-9E9D-05C8B1046A45"); messages.Application.Id = new Guid("my app guid"); messages.Application.Name = Application.ProductName; messages.Application.Version = Application.ProductVersion; Dotfuscator.MessagingServiceV2 s = new Dotfuscator.MessagingServiceV2(); s.Publish(messages);

  • Save application preferences... registry/file?

    - by spender
    Where is the best place to store application preferences? In particular, I'd like to save preferences for a media player such as volume levels and the like. Two candidates spring to mind... file and registry. Which would be more appropriate? As a follow up to this, I'm also wondering if there are any APIs that aid in creating application specific settings. Unless someone advises me that this is wrong, I'd like to save stuff either in HKCU... or HKLM/Software/MyCompanyName/MyAppName/Key for the registry, or in %APPDATA\MyCompanyName\MyAppName\someTypeOfSettingsFile. As these seem to be commonly used for such settings, I'd assume that .Net makes it easy to store settings in these locations. Is there a simple high level API that can .Net offer me to read and write settings to these common locations?

  • How can I notify an application of a programmatically set scrollbar value?

    - by Frerich Raabe
    My code involves standard Scroll Bar control and it happens that I need to change its value programmatically in some cases. I do this using SetScrollInfo function, as in this example: void setScrollBarValue( HWND scrollBar, int value ) { SCROLLINFO si = { sizeof( SCROLLINFO ); } si.fMask = SIF_POS; si.nPos = value; ::SetScrollInfo( scrollBar, SB_CTL, &si, true /* redraw */ ); } This appears to work fine (the thumb of the scrollbar moves around) but it fails to notify the rest of the application of the new scrollbar value. For instance, an edit control which uses the scroll bar (much like in the Windows notepad application) fails to scroll around because it doesn't get notified about the new scrollbar value. In case it matters: the scrollbar I'm modifying is not in the same process as the above setScrollBarValue function. Does anybody know how to achieve this?

  • What is the easiest way to deploy a MVC2 application from Visual Studio 2010 to IIS 7.5?

    - by Richard
    I´ve tried a couple of different ways to deploy a application to a IIS 7.5 running on my machine for testing purposes and i´ve sort of hit a wall. Nothing works out of the box. Everything assumes I have knowledge I don't have and would prefer not to have to aqquire. Google isn't really helping either with answers ranging from "copy files by hand" to "install teamcity and set it up for CI". I have set up TeamCity for java projects before and it's really over kill for my needs at the moment. So anyone know of a fast, simple and easy way to deploy a application during testing/building?
