Class Libraries (.dll's) Referencing Other Class Libraries (.dll's)?
Dec 17, 2010I designed 7 class libraries for 1 project.The project references all 7 libraries.3 of the 7 libraries make references to the other 4 libraries.I thought of just duplicating the code that's referenced in the other 4 libraries, but thats a lot of code.
Example:
PrjctA makes reference to LibA, LibB, LibC, & LibD.If LibA references LibB & LibC also will this fail?
Class Libraries (DLL's) In .Net?
Dec 3, 2009I'm creating an application that will utilize a lot of functions for performing scientific calculations. There will also be a lot of 3D and 2D rendering in my application. Hence i will have a lot of common functions that will be utilized frequently.
I have noticed that class libraries (DLL's) are utilized in applications similar to mine, and am wondering if i should utilize them in my application. The trouble is, i can't really think of what use they will be to me. The functions in my application will only be called upon by my application, so i do not need to make my functions accessible to others. The only other benefit i can see from using DLL's is reduced memory usage and .exe size.
Whats the benefit of using DLL's instead of just creating a bunch of modules in my application to store my functions? I have read that another benefit of using DLL's is they are easier to maintain and update as you can update the DLL rather than your entire application. I dont quite understand this, as if you are going to utilize new and updated functions you have added to your DLL's, then you will need to update the code that calls them as well. So again i don't see the benefit in using DLL's in my application.
Exceptions In Class Libraries?
Dec 6, 2009I'm creating a class library that contains a series of functions with Try...Catch blocks to handle errors. When i run another application that uses the class library, and call a function in the library using parameters that i know should cause an error (i.e. divide by zero), i don't get an exception thrown.
Can you not use Try.. Catch blocks in external libraries? If not, how are you suppose to handle errors in these functions?
Localization In Class Libraries
Aug 31, 2009I've just about finished my WPF app, but I just hit a hurdle: my app needs to be totally localized (I've achieved this using databinding/RESX files & multiple cultures), and the actual program does this My problem is that I have a window where you generate reports on your progress.It's designed so that programmers will be able to design their own 'report sections', using interfaces & class libraries.Just one problem though: when I use RESX files inside these class libraries, they won't actually change even if I set their culture to the relevant culture I want to test.

View 3 RepliesVS 2008 Class Libraries - Not Compilled?
Oct 19, 2009I'm looking to create a bunch of re-usable classes. I understand the strength of creating a DLL that is reusable, but I would rather keep them un-compilled. When adding an existing .vb file, visual studio makes a copy of that object instead of a simply reference.Is there any way to do this or creating a class library with .DLL the only way?
View 6 RepliesRemove Default Namespace For Class Libraries?
Jan 14, 2011I've wrote a class library in vb. it only has a class called MathEx. Now when i add a reference to a test project, i had to refer to the class as MathEx.MathEx is there anyway i could refer to the class as simply MathEx? (in other words i do not wish to have the default namespace added to my class libraries)
View 1 RepliesC# :: Reference Configuration Information From Within Multiple Class Libraries?
Mar 13, 2009I've got a bunch of DLL projects that I'm pulling into my application, each contains their own Settings.settings/app.config. When I compile the app and run for debugging, everything works just fine, but come deployment time I can't get my DLLs to read their own settings files.I've been doing some reading and it has become apparent that there's a couple of methods to getting each dll to read its own configuration - one is to dedicate a .dll.config to the library and the other is to embed the dll's configuration in the process.exe.config.I'm having significant issues trying to implement either and I wondered if anyone has any good docs on this - there appears to be a shortage on the Net.
I'd like a separate .dll.config for each of the libraries if possible, but in a pinch, getting each of my libraries to read their own section of the process.exe.config will he right direction because I'm so close to rolling this application out but this stumbling block is causing me a significant headache.Edit: When I merge the configuration files, I start getting TypeInitializer exceptions when I initialize objects withing my libraries. This is likely just me being retarded, but does someone have a working example of a merged config file and some basic demonstrative code for reading it from multiple assemblies?
VS 2008 Handling Exceptions In Referenced Class Libraries
Jun 8, 2010i created a Class library (.dll) and loaded it as reference into a main project. In the code for the class i've handled exceptions using try..catch subs, however when debugging the main project exceptions that are handled in the DLL still get thrown! (the class ".vb" file gets loaded into the debugger and the line of the exception shows up)
Up till now i've found it useful that when an unhandled error occurs in the imported reference, it shows up in the main project with tracing back to the referenced class. But i dont want the exceptions that are handled in the reference class to be thrown when debugging the main project!
As you can see the exception thrown was handled with try...catch this class exception.vb belongs to the project that created the class library (.DLL that i referenced). i didnt even load the project that built the reference so it amazes me that it could find the coding class to begin with.

View 1 RepliesShow MessageBox From BackgroundWorker?
Jan 18, 2010showing MessageBox's from background workers.My program is a utility that has several functions and each function is boxed in a UserControl and then placed on a TabControl on the main form. A few of the utilities are batch functions that take quite a bit of time to complete their task. In order to allow the user to use the other utilities while a batch utility is running I make use of the BackgroundWorker class. It's quite handy!
My only problem is when I need the user to interact with the background thread, usually due to an error condition. I want to be able to halt the thread and display a MessageBox to the user. At first when you just do it from the background thread as demenstrated in the code below, it appears to work fine. But the MessageBox is not actually parented by the Form. If you select the Form, it will hide the MessageBox and the user thinks that the program has stalled. What's worse is that my program has a setting to allow the user to make the window TopMost, which means that the form will always hide the MessageBox when TopMost.
Option Strict Off
Public Class Form1
Private Sub chkTopMost_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chkTopMost.CheckedChanged
Me.TopMost = chkTopMost.Checked
[code]....
I have thought about passing the message using ReportProgress(), but the problem with this is that the BackgroundWorker will not halt it's opperation, and there is no built in mechanisim to send a message back to the BackgroundWorker.

View 5 RepliesDifference Between MsgBox And MessageBox.Show
Jan 10, 2012Is there any difference between the two:
msgbox()
messagebox.show()
Some tutorials use msgbox() some use the other messagebox.show()---I see that both can have an editable style but I was wondering why there are two.
Is it to accommodate for older programmers (who have learnt on an older version of visual basic).
