  • .Net Designer assemblies, C++\C# error

    - by greggorob64
    I'm working on an designer-heavy application (using Visual C++ 2.0, but a C# solution should still be relevant). My setup is this: I have a UserControl named "Host" I'm attempting a UserControl named "Child" Child contains a property to a class whose type is defined in a different dll entirely, named "mytools.dll" Child works just fine in the designer. However, when I go to drag "child" onto "host" from the designer, I get the following error: Failed to create component 'Child'. The error message follows: 'System.io.filenotfoundexception: could not load file or assembly MyTools, Version XXXXXX, Culture=neutral ..... {unhelpful callstack} If I comment out the property in "child" that points to the class in mytools.dll, everything designs just peachy. I have the property marked with "Browsable(false), and DesignerSerializable(hidden), and it does not help. Is there a way for me to explicitly say "Don't load this dll, you won't need it in design time", or some way for me to force a dll to load from the designer programmatically? Thanks!

  • Odd Tools and Techniques for System Administrators

    - by Joseph Kern
    There's been a lot of questions centering on Software Tools for System Administrators. But I would like to know about any odd physical tools or techniques that you've used; Something that you never expected to be useful, but ended up saving the day. I'll go first: A Camera Phone. An application server had a major power issue that borked the RAID. Many of the disks were offline. Before I took the plunge and forced disks back online, I took a picture of the RAID BIOS screen with my camera phone. Having the exact layout of the RAID stored safely in my pocket, I was able to reset the RAID, and reboot the server. What odd tools/techniques have you used?

  • Outlook receives winmail.txt attachment instead of Excel, PowerPoint or Word attachments from Lotus

    - by Philippe
    Ok so the title pretty much says it all. We are offering a Hosted Exchange solution for our customer. Everything is working fine except for one customer complaining that he is receiving winmail.dat or winmail.txt attachments instead of the actual Word Excel or PowerPoint attachments he should be receiving, only when these messages come from a specific European senders, that is using Lotus Notes. I know that usually the problem is coming from Outlook senders to other mail clients, but this is not the first they inform me of this but I can't find anything on the matter so far. Has anyone ever gotten and solved this problem? If not, does anyone have any idea regarding this? I had solved this problem a few months ago, by upgrading Outlook to SP2 and then uninstalling it using the Service Pack removing tool of Microsoft. It seems that only the latest SP1 version could work but not the SP2. The problem is that now nothing is working at all. Thank you for your help, Philippe

  • Looking for way to download all the free software I need to setup my PC all at once . . .

    - by Jim McKeeth
    I am in the middle of reinstalling Windows 7, and I would like to install all the software in as few steps as possible. I saw a web site recently that listed a lot of different Freeware and Opensource appliations. There was a checkmark next to each one so you could select the ones you want, and then they would all download in a single package to install at one time. The idea was for when you were setting up after a fresh install. It was for Windows and they were adding 64-bit applications.

  • C#/MonoDevelop: GTK MessageDialogs require a doubleclick to close - why?

    - by Connel
    I'm a newbie programmer writting a program in MonoDevelop in C# and have a porblem with my gtk MessageDialogs. The close button on the window boarders of my GTK Message dialogues require a double click to actually close them. The close button on the dialogue its self works fine. Could someone please tell me how I can fix this below is the code: if (fchDestination.CurrentFolder == fchTarget.CurrentFolder) { MessageDialog msdSame = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "Destination directory cannot be the same as the target directory"); msdSame.Title="Error"; if ((ResponseType) msdSame.Run() == ResponseType.Close) { msdSame.Destroy(); } return; } if (fchTarget.CurrentFolder.StartsWith(fchDestination.CurrentFolder)) { MessageDialog msdContains = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "error"); msdContains.Title="Error"; if ((ResponseType) msdContains.Run() == ResponseType.Close) { msdContains.Destroy(); } return; }

  • Add custom Model Binders for derived objects and their base

    - by mare
    My class diagram: BaseContentClass Page inherits BaseContentClass Tab inherits BaseContentClass ... If I do this ModelBinders.Binders.Add(typeof(BaseContentObject), new BaseContentObjectCommonPropertiesBinder()); then when in controller action parameter of type Tab appears, custom model binder is not fired. It gets fired if I do this: ModelBinders.Binders.Add(typeof(Tab), new BaseContentObjectCommonPropertiesBinder()); But I don't want to go writing "n" number of Add statements in my global.asax.cs to associate all the derived classes with my custom model binder, do I? I don't know if I have any other option.

  • Controlled execution of computationally expensive tasks

    - by Sergio
    Say you have an application where a user is typing some text and as she types you'd want to perform some expensive computations in the background (related to the text that is being typed). Although you would like to do lots of things, your main priority is that the system responsiveness stay at acceptable levels so the user doesn't notice such a heavy load. Is there a way (ideally platform/language independent) to control what algorithms should be executed in the background based on the system load and responsiveness?

  • Java API for source formatting

    - by Marty Pitt
    Hi There are several PHP or js code formatting libs out there -- does anyone know if similar libs exist in Java? Ie., Given a string of code, return a formatted string with syntax colouring etc. It'd be ideal if it auto detected the language, but I might be pushing my luck there...

  • ASP.NET MVC - separating large app

    - by marc_s
    I've been puzzled by what I consider a contradiction in terms: ASP.NET MVC claims to be furthering and supporting the "separation of concern" motto, which I find a great idea. However, it seems there's no way of separating out controllers, model or views into their own assembly, or separating areas into assemblies. With the fixed Controller, Model and View folders in your ASP.NET MVC, you're actually creating a huge hodge podge of things. Is that the separation of concerns, really?? Seems like quite the contrary to me. So what I'm wondering: how can I create an ASP.NET MVC solution that will either separate out controllers, the model, and the folders full of views, into separate assemblies? how can I put areas of ASP.NET MVC 2 into separate assemblies? or how else do you manage a large ASP.NET MVC app - which has several dozen or even over a hundred controllers, lots of model and viewmodel classes, and several hundred views?
