View 3 RepliesVS 2008 Can Call A Class From Main Form
Dec 14, 2011As of the moment I have 24 buttons that are keys to a piano.24 of the button codes have a call method that calls the note to be played.24 of the private subs that are called have an .wav audio playback command within them. I was hoping I could move the .wav private subs into a separate class, and just call them from my main form, therefore cleaning up the lines of code I have at the moment. [code]That example only counts for one Button "The Key of C", and the audio file that is called with it. Multiply that by 24 and you get a big mess of repetitive junk.Can I move the audio subs into a class and call them from my main form?
View 16 RepliesCall To Application.Run(New MyForm()) Not Working When Called Outside Sub Main?
May 2, 2012I am using Compact Framework 3.5 on a Symbol MC50.In my Sub Main it first checks to see if a database exists. If it does, it shows a login screen using the following code:
Dim login As frmLogin = New frmLogin()
If login.ShowDialog() = DialogResult.OK Then
Application.Run(New frmMain())
End If
This all works correctly and, when I close frmMain, it exits the application as expected.However, if the database check in Sub Main fails, I call the ShowDialog() method of another form that is used to create and fill the database from a live server. Here is the code for calling this form:
If Not File.Exists(SETTINGS_LOCALDB) Then
databaseExists = False
MessageBox.Show("Local DB does not exist. The database must be created before using the application.")[code].....
All of this code is being hit and frmMain does indeed load. However, when I click the close button in the top right nothing happens, no event occurs. Its as though the Windows events are not occurring.

Modal Panel With Asp.net Being Programmed
Apr 9, 2009I have an ajax modal panel with a div on it that I access from the server and dynamically insert a table into, by showing the values of various controls on the calling form.My problem is this, it works fine if all my controls are doing auto postback, but it ruins the user experience, because tabbing through the controls, the controls lose focus during the automatic postback.Is there a way to have my target control perform a postback, before it puts up the modal, so I can retrieve not posted controls data in the modal?

Update: Well i figured out what was wrong. VS2010 had removed all the "handles button.click" behind the subs. And it won't create them when i dubble click a button i program time.
Main Procedure Call A Sub Procedure To Display Values Of X / Y And Hypotenuse
Dec 1, 2011The instructions are as follows:
1. Write a Visual Basic Console Application.Inside the main procedure call a function procedure to input and return a value for a double variable called x, the width of a right triangle.Inside the main procedure call the same function procedure a second time to get a value for a double variable called y, the height of a right triangle.
2. From the main procedure call a function procedure which calculates and returns a value for the hypotenuse equal to the square root of (x squared + y squared).You will have to pass the values of x and y to this function procedure.The procedure should calculate and return a double type value.The value that is returned by this function procedure should be equal to the square root of (x squared + y squared).
3. Also from the main procedure call a sub procedure to display the values of x, y, and the hypotenuse.

Aug 3, 2009I am trying to autoselect pre-programmed items in a listbox when a form opens with the control on it.but i cannot find a proper method to select all the items in the listbox and hold the resulting text as a string that will later be saved to a text file. i do not need help with saving the text to file but rather selecting the items in the listbox.so, after alot of trial and error and no luck I think I am supposed to use
ListBox.ObjectCollection

Prevent The Class Library's Files From Being Opened During Main Project's Debug Mode?
Jan 24, 2009I made a Class Library project that contains the main classes that my Main Project needs because I don't want to main classes when I distribute my project. I've successfully called and used it in my Main Project. But when I started debugging and stepping through my code which involves calling and using the class I wrote in my Class Library, I noticed that the class' file in my Class Library opens up during debug mode.
how can I prevent the Class Library's files from being opened during my Main Project's debug mode?

May 12, 2011Is 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)
.net - Feedback From Threads To Main Program?
Jan 27, 2011My 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?

View 1 RepliesPlugin Which Is Dependent On Main Program?
Jan 23, 2012I 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 2 RepliesCheck Out The Program It Looks Like The Main Form Is Not Being Updated?
Dec 16, 2011I 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.

Should Threads Update Global Data In The Main Program
Mar 18, 2011I 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).

Apr 27, 2011I 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.

Php - Load And Call Files Dynamically?
Nov 24, 2010I'm having one basic aspx script that needs to load some "plugins". Every plugin has its own settings and it should perform different logics. What i'd do in php is create a class for each plugin, load that class, pass the settings file to it and call some method on that class that would give me some output. But is it even possible in vb.net? I'd need to have multiple files with multiple classes, load those files, depending on the plugin name and call some method on them to parse that plugin's settings.
