Is it possible to use a sub Main() to start you're application rather than a form, if so how? Also how do you implement the cmd commands such as "[application path here]program.exe colourclicker" The above command would start the program but would only show a certain form.
EDIT Is there another way other than unchecking the 'Enable Application Framework' checkbox? (As this disables XP Styles and uses the ugly classic windows styles)
Me.Focus() doesn't do the trick, my program is hereQuote:

I feel like the answers I seek are rather obvious so I feel silly for having to ask, but I just can't seem to figure this out (I'm new to threads, and am really only comfortable using them in Java at the moment). I have an Excel Addin application created with VB.NET, and I've noticed that occasionally while it's running some code (it's no one specific block of code) the program execution will just stop. This is especially problematic when I've set ScreenUpdating to False for Excel because the users then have to completely close out of Excel to get ScreenUpdating to true.

Trying to get it to behave like C#, where there is a Program class with a static Main method.However, in the project properties, I cannot set Program.vb to be the startup object, only the forms (it is a forms application).
View 2 RepliesI have a solution with more than one project and the main project contains buttons to open forms from different projects that are in the same solution. Say Project1 is the main project and Project2 is the different project that gives the following error when i compile it:
Error 3 'Sub Main' is declared more than once in 'SystemInformation': SystemInformation.Program.Main(), SystemInformation.My.MyApplication.Main(Args() As String) System Information II
I have already seen other threads with this question but it does not work for me because i have more than one project.For Project2: Application Framework is disabled and the startup object is "SubMain".
Recently i bought the book by Troelsen about VB and the net and tried to run the programs e.g.:

Sub Main()
EntryPoint.Main()

I had to add the first sub "Main" otherwise it would not run. Is it possible to do without that sub in the way member OLiver does in the examples he provides?
Is there a way to start your program from the sub main() like you could with vb.net

View 4 RepliesMy software will simulate a few hundred hardware devices, each of which will send several thousand reports to a database server.Trying it without threading did not give very good results, so now it's time to thread.Since I am load testing the d/b server, some of those transactions will succeed and a few may fail. The GUI of the main program needs to reflect this. How should the threads communicate their results back to the main program? Update global variables? Send a message? Or something lese?
Now, if I update only at the end of each thread then the GUI is going to look rather boring (and I can't tell if the program hung). It might be nice to update the GUI periodically. But that might cause contention, with threads waiting for other threads to update (for instance, if I am writing to global variables, I need a mutex, which will block each thread which is waiting to write).
I'm new to threading. How is this normally done? Perhaps the main program could poll the threads, instead of the threads iforming the main program?
Im trying to make a program that has a main form(menu form) and when i click on the buttons another separate form will appear.
View 1 RepliesI have developed an application with a plugin architecture using interfaces. I realized that when I release the API for 3rd party plugin development, someone would be able to create a loader program to replace my main program quite easily. Is there any way I can make the plugin dependent on my main program? All my main program does is get an icon and a description of the plugin from the DLL plugin (using the interface) and then calls the dll's interface function to create and display the form.

View 1 RepliesI have an application I've written for some of the people at work and there is one bug that I have no idea how to solve. The application is multithreaded so that the main form can be updated with new information as it comes in. Throughout execution, several other forms come up as well (one at a time).Every so often I get reports that the program freezes. When I check out the program it looks like the main form is not being updated(checkboxes are see through, textboxes are blank) and the main form can't be moved around. This only seems to happen sometimes when the program is left for long periods of time (+30 min) and only on the released .exe and never in the debugger(as of yet). I've tried leaving the program running overnight and it had no problems.
View 5 RepliesI want to launch a bunch of threads, each performing the same task, and know in main() when each finishs and it if it was successful or failed.The solution offered was to use a ConcurrentQueue, but other posts have recommended using a BackgroundWorker Class, or a thread pool.Is there a definitive answer?Again, all threads perform the same code and have a pass/fail result. I want to run more than there are available threads so as soon as one thread finishes I will launch another asap - I want tehm to stress a remote systems as much as possible (reather than stressing my local PC with too many threads, so I will need to experiment to determine the optimal number of threads).

View 4 RepliesI have an application that just stores shortcuts to most used applications on users desktops. My problem is that when the machine loads after they login the app window looses focus and sometimes doesn't show in the taskbar. I tried to use Me.Focus() but that just gives the treeview focus and not the form itself. I mean the parent has focus in the treeview but the form is not highlighted, I can then click on the form and it gets selected.
What is a good way to get the whole form focus? I used me.focus in the form load too.

View 2 RepliesI have two applications. For performing certain functions, i run a second exe, via a process, and wait till it is complete (exited) to continue with my main application. I run through many repetitive functions on different files.Everything runs fine however, when i am doing a run and it is on the x loop number, the main application seems to halt the secondary process exe. I can only assume this is what is happening as, if i close/stop (not pause) my main application in VB, the second exe continues from where it was halted until it completes.
View 4 RepliesI was just wondering how you can make classes import into your main Form.vb
Let's say I make a class with the following.

Form1.Hide()

How could I make the Form1.vb include the things that are in OtherStuff.vb.
All of the solutions that I have tried come up with the same error. Reference to a non-shared member requires an object reference.
I'm a noobie coming from VBA. i thought i'd try my hand in VB (because this stuff is fun). I'm trying to make the main window for an application. i've created 2 forms so far. one entitled "Main" and the other "Form1". I would like for "Main" to be the main window of the application.

The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?
I have a program that starts another program after setting the regkeys basically the program continually syncs the calandar of outlook and another application.I set the regkeys than launch the c:sync.exe app. I have tried a simple process.start and launching the process as a thread and they both do the same thing: The other process starts and works as it should but my main program goes "White screen" or "not responding" until the process.start has exited.
I want the process.start to run in the background so if users click in my main app it responds and truly that they can access the context menu of my main app from the taskbar while the process.start is running.
is it possible by 1 program to save settings to another program without running the program that is being edited?
