I want to start my project with a sub main by disabling the application framework. The problem is that if i do this then the application starts and then exits in a few moments. Is there a way which could hold it until the last form is closed.

I have created one Windows form based VB.Net project in which I want to start my project with Sub Main()
I have added one module and created one Public Sub Main() method but when I am trying select Sub Main from Startup form, I am not getting the method there. I am using VS 2010
I am developing a commercial application that needs to do some environment checking upon start up. I need to check things like the following. 1. Is there a registry entry on this machine that has various keys for paths to SQL Server 2. If it does not I need to create them. 3. Prompt user for the path to the SQL Server 4.Check the SQL Server to see if the database I need exists. 5. Create the DB if not. 6. Populate the DB with the tables I need 7. Create stored procs in the DB 8. Write the registry. I could do all this in the form load of the main form. However is there a better way? Like doing all these checks as part of a splash screen for example.

I have tried declaring 'Public Sub Main' on my forms and in some modules, yet in my project properties, it is not one of the options.
I'm making a security program that locks the users screen. I have already figured out how to disable task manager but now I need to disable the task bar from showing and the start menu. Also, trying to do an event on alt+F4 doesn't seem to stop the program from exiting. Any other solutions? This program is intended for security reasons and I am not using it for any viruses.

I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?
View 2 RepliesIn vb.net 2008, when I start a new project, it defaults to "Enable Application Framework." I add the following code to a button click handler to the main form in the new project:
Dim k As Integer
Dim s As String
For k = 1 To 5000000
s = Mid(s & k, 1, 30)
Next k
End Sub
Then, when I try to break execution to debug using the pause button, I get the message "No symbols are loaded for any call stack frame. The source code cannot be displayed." If I uncheck the "Enable Application Framework" project option, it breaks and debugs properly. (This also happens with other code not just this example).Is there a way to disable the Application Framework by default in a new project?Is there a setting that will allow a project with Application Framework enabled to break and debug? Did I mangle the installation? This is a recent VS2008 installation. Is there some option I should have selected during installation?

View 1 RepliesMy intentions are to add command line switching. I am trying to see if i could run my application in varoius ways i.e.
App.exe -S - Start the application in XX Mode
app.exe -T30 - Start application with 30 second delay
and that kinda switching.
I have a solution that I wish to upgrade from Vb.net framework 1.1 to framework 4.0. The solution consists of a number of projects, all but one of which compile to dll's. The master project compiles to a executable which provides a menuing system which dynamically loads the dll's and connects to entry points.
The projects contain normal classes, numbers of forms and also controls, which are either usercontrols or are inherited extensions of standard windows controls.There are a number of third party components (eg reporting and grid controls from Component One, Ribbon control from DevExpress etc).

How do I start up with sub Main? I created a sub Main in a class. I clicked properties on my project. It provided a combobox of possible startup forms, but nowhere could I find an option to choose sub Main.

I want the program FIRST show me the screen and after i see the form to start load the file I have try with the 'Application.DoEvents() and System.Threading.Thread.Sleep(200) without any effect?
I have a startup form with one list view and one combo box. When combo box SelectedIndexChanged a make call a subroutine that perform read of a file.

I'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.

Since I'm unable to publish my main project, I've decided to start from scratch to see if I can locate the problem. I created a brand new project, just a simple form and dragged 4 controls onto it (a label, a button, a combo box and a checkbox). There is no code in any of the controls.I published this using Clickonce at url...(I'm aware people may not be happy clicking links). It's set to run only from the webpage. It runs fine on this PC, but on my friends PC and on my spare PC, it simply churns up a page of html error codes.
View 6 RepliesI have an application with a splash screen which gets shown before the application starts. One of the requirements of the application is to allow users to restart (or atleast clear the form) so that other test cases can be ran. Because there are so many forms and variables, we elected to simply call Application.Restart() to accomplish this.
What we would like to do now is disable the Splash Screen when Application.Restart() is called. That is, only show the Splash Screen when the application is initially started, not when it is restarted.
I have a VB.NET project (main.exe) and include an additional .exe application as internal resource. Now I do not want to run the extra .exe as a separate process but want to attach it to the process of main.exe so I have just 1 process overall and not 2.

View 2 Repliesthe client has asked for all forms and classes to be hidden from the main project, so when he sells it, they will only be able to see part of the project and not all the classes and forms.My Solution: I have created another project called project2, and added all the forms and classes from main project, fixed all errors and compiled it.I deleted all the forms from the main project and added a reference so that it gets all the forms from the other project by referencing the dll file, but it does not seem to work and get a lot of errors.is there an easier way of hiding the forms and classes from the main project or do I need to do more then just add the reference.
View 2 RepliesI don't think this is possible but thought I'd just double check...
I have a class library project (i.e building this project results in a DLL being created) and I add a reference to this DLL in several of my other applications. This DLL project targets .NET Framework v2.0.
However, some of these apps that use the DLL target .NET 2.0 (or 3.5) and some target .NET 4.0. But because .NET 4.0 does not include 2.0 and 3.5 in it, its possible for someone to have .NET 4.0 installed but not .NET 2.0, therefore meaning that they won't be able to run my app because of the reference to a DLL that requires .NET 2.0.
So the solutions as far as I can see are: 1. Include .NET 2.0/3.5 as an additional prereq for my .NET 4.0 apps... ewww. 2. Create a copy of this DLL project and make it target .NET 4.0 then in my .NET 4.0 apps add a reference to that rather than the .NET 2.0 version.
So far I've been using the second option, which is working fine but its just very annoying having to remember to copy and paste any changes I make in one version of the DLL project into the other one.
So is there any way I can have a single DLL project but have it build 2 versions of the DLL, one targeting .NET 2.0/3.5 and one targeting .NET 4.0? As I've written this down I've just realised I could always build the solution, copy the DLL out to another folder, then change the target framework and build it again to get the new DLL but that's still not ideal.
Using VS 2010 Ultimate by the way in case that makes any difference to the options I've got available
