• NILKAMAL How to access settings created by the SettingsSingleFileGenerator from another assembly?

  How can I access settings created by the SettingsSingleFileGenerator from another assembly Is it possible to tell the SettingsSingleFileGenerator to create a public class instead of an internal Or how can I access my settings Greetings Harry Thank you Harald. My apologies but I do not understand what is meant by adding just a class as a link. Are you referencing the assembly to get to the class I am interested in a IDE-friendly solution also. Ideally I simply want the class generated as public since every update via the designer sets it back to internal. ..probably a bit late in coming but there are two ways of fixing this: 1) Hack the generated source file to make the generated cla ...Show All

• Greenstrike Intellisence Doesn't Remember Last Session

  I have visual studio 2003 installed on my computer. The intellisense was working just fine until I installed VS 2005. I don't know what happened but now everytime I start VS 2003 it doesn't remember any of the recent intellisense commands. Ex: If I type "System." it should come up as "System.Diagnostics " instead it selects the first item in the list. If I repeat the process in the same session it goes right to "System.Diagnostics". Is there anyway to fix this I found the option at Tools => Options => Text Editor => C# => Formatting. It was already checked so I unchecked it, cleared the history and rechecked it. I will see if that solves the issue Eva ...Show All

• glasgow1 Does C# 2005 support coding RS232 serial communications?

  It seems VS.NET does not support RS232 serial communications, many people choose to use VB MSComm to do serial communications. Besides, we can also get " Use P/Invoke to Develop a .NET Base Class Library for Serial Device Communications " source code and to apply it in our application from : John Hind's CommBase( http://msdn.microsoft.com/msdnmag/issues/02/10/netserialcomm/ ) However, to get VB MSComm means to buy another software. Does VS 2005 has solved this problem and has some built-in functions to support RS232 serial communication Is there any example about this Thank you! Of course you can! I used it with C#... But there could be a problem. I was getting some garbage data when I read from the stream contin ...Show All

• james_cline_ Interfaces - a beginners question

  Hi all, In most of the books I've read on C# they make the statement "C# only supports single inheritance, but you can implement as many Interfaces as you wish". To me, this seems to suggest that Interfaces serve a similar purpose to inheritance, but from what i've read and understood, this doesn't seem to be true. To my mind, an interface simply gaurantees that anly class that implements that interface will have those methods/properties the interface requires. However, as far as I understand, each class that implements an interface has to contain all the code necessary to implement that interface; so, for example, if I have two classes that implement an interface, then each class has to have its own code for that implement ...Show All

• su45937 Sending email using enduser's default mail settings

  Hi, I need to add simple email capability to my app but I don't want to bump into issues like end user smtp authentication, etc. Is there a simple way to automate end users default email client to send email Thanks ! Thanks very much. Pity smtp authentication is necessary to protect us from evil. unfortunately not - you need to supply the SMTP class the correct credential details as well as SMTP gateway, or use your own :-) The end user may not have a default email client, or if they do then you could probably use the email client to send an email but they would have to hit the "send" button. You could use the outlook COM interop approach but agai ...Show All

• PeterTPeterT How many threads should a process possess?

  Hi, everyone: My application runs with its thread number ranging from 40 to more 60. I wonder how many threads a windows process should have. I have checked a lot only to find that the general MaxThreadNumber for ThreadPool is "25". But how about threads created by Thread.Start Further more, after Thread.Start() was executed in my application, I was surprised to find the the thread may remain "Unstarted" under a uncertain condition which brings about a hang-up. Does this happen just because of too many threads in my application Thank you Thank you very for your reply.I will have a good look at the attached site.

• Bjoern.Greiff FreeAllUnusedJunk() ? any such method?

  I've got a program that runs through a loop, and during this loop, consumes a lot of RAM. of course, .NET is smart, and auto-disposes.. so the RAM usage goes something like.. 40MB, 80MB, 115MB, 230MB, 307MB, then it drops back down to something small again. The thing is, when this loop is over with.. the process could be eating up 40MB RAM, or 300MB. Is there some kind of global method I can call that basically frees up ANYthing that's not in use So why wouldn't you recommend calling the gc.Collect() I want to use it in my application. its bad practice and should leave the GC to do its own thing without interferring with it otherwise sometimes you will have undesira ...Show All

• Francis Tracey AppDomain and WinForms performance issues...?

  I have a bootstrapper application which needs to be able to launch one of several different versions of my application (for clarity I'll call these versions the SubApp). I have chosen to do this using AppDomains... If I run my SubApp on its own (either via the exe or from the IDE) it runs perfectly and performs really well. However, when I run it inside the AppDomain from within the BootStrapper app the performance is definitely slower... The first form takes around 10 seconds to appear (a oppose to about 1 second running directly) and even after that, there is a noticeable performance degradation when loading new forms, etc... Each SubApp version sits in its own directory, so I use the following code to create the AppDomain: // Cre ...Show All
