Start Creating An Application API In NET?
Mar 10, 2009
In the company I work for we have a desktop application developed in .NET that we like to open up some parts for other software developers.
I see it like some kind of public methods that other software can access. Is there any standard approach, best practices or other experience of this?
I guess you could do this with Win32 calls, C/C++ programming etc. But I'm mainly a .NET developer and have some years of experience programmming in mainly VB.NET but also some C#. I hope finding a way to do this within .NET. But it should be accessible for software developed in other languages.

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)?

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.

Visual Basic 2010 - Net Framework 4.0 Client
I have an application (application #1) running with Administrator privileges on Windows 7.
I want application # 1 to start another application (application #2) without Administrator privileges so application #2 is running as a standard user.
Is there a way to do this? I have been using Process.Start.

I figured it out. Check out the finished control [URL]..I'm trying to make myself a simple 'star rating' control.
It would have the properties:
StarCount (number of stars)
StarValue (number of stars highlighted)
I want to draw the stars using GDI+, have them highlight on mouse over, and change the StarValue when clicked.I have an idea on how to do this from experience with working with forms, but I'm having some difficulties with the Control development part. I couldn't find any tutorials which didn't inherit a control (such as a checkbox or button), and I have no idea how to make my control editable in the designer.
I think what I need to do is create StarCount as a property like this:
[Code]...
I also want to execute my drawing code at design time, so I can see the stars while laying out a form. as a side note to that, I don't know how to change the size of the control at run or design time, nor how to disable the user from changing it at design time.as a side note - I know that there are a few star rate controls already floating around the internet, but I do not like the quality of them (or at least the one's I've seen), they felt very windows 98. I'm trying to make something that will fit well into windows 7 (plus I want to implement custom images, but that can wait until I get it working)

I've built a couple of Apps successfully, but having published them to a Network Folder, Non-Admin Users can't install them themselves because the Install attempts to create an Entry in the Start Menu. There may be other Security issues (I need 4 of the permissions included if I publish it as a Partial Trust Applications, which I think affect this) after this point that I'm not aware of, but yeah, it fails when trying to create a Start Menu item -
+ Access to the path 'C:Documents and SettingsJameOStart MenuProgramsMynas' is denied.
I think excluding the right is just part of the SOE, but is there some way I can create this and have it NOT create a Start Menu item, haven't been able to find any?

I am installing an app I built in VB, and am getting the error "Application validation did not succeed. Unable to continue." I have successfully built and installed this app previously. What I think caused the issue is I attached the .mdf file I have referenced in my application to my SQL Server. I then detached the database in SQL Server, opened my VB app and re-built the app. When I tried to install the app, I received the error. Attached are the details of the error message.

I'm using Process.Start method to launch another application from my application. Until today, there was no problem. But I have tested my application in a different OS, Windows XP (SP3), and my application didn't work right on that. I'm also using arguments to run that application. I guess for some reason my application couldn't send arguments to other application correctly under Windows XP. Maybe it is related to my code. But you should know, it works great on Windows 7.

Is it possible to create a custom start menu shortcut link?
The only possibilities I see in the setup project are shortcuts to folders or primary output.
Update:
What I ended up doing is creating a custom action on commit that dynamically creates the link using Windows Scripting Host. Then on uninstall, removing the link.

I worked on my project and then compiled it and I am trying to install it and test it on user machines it allows me to install the app but when its time for the app to start up it gives me the "Application cannot start error".There is a line in the details log that says "Unable to install this application because an application with the same identity is already installed. To install this application, either modify the manifest version for this application or uninstall the preexisting application." , The thing is I first uninstall the program before I attempt to install it again on the machine after testing it and fixing some bugs in the software.I've tried restarting the machine , antivirus scanning what more can I do to fix this?

I want A application that im going to make in VB.NET to load on Startup. I found a few topics on Windows Service for creating a start up service but then I read that you can't use it to load up a form. So there must be a way to have your program load on a computer when the user turns on or log's in at startup.Thing is, this application is going to be installed on many computers and people wont like having to remember to run it.

I am concerned that I may not be allowing applications to clear out of memory before they close.I normally start a new application with a start-up form and set the application's shutdown mode to "When last form closes".
I have noticed that any application that loads a class does not close when the last Form closes. I have tested this by creating a new project with a single Form and single Class (newly created and empty). When I declare this class in the Form's Load event then the application does not close when the form is unloaded.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim MyNewClass As New Class1
MyNewClass = Nothing
End Sub
In order to get the application to close I need to add Application.Exit in the Form's FormClosed event.
Private Sub Form1_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
Me.Dispose()

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.
