I have a single instance VB 2010 application I know how to communicate with the next instances run through the StartupNextInstance application event. The usual way of working with this is parsing command line arguments of the new instance and continue execution of the old instance. What I would like to do is replace the running instance with the new one. Is there any way to do this other than disabling the single instance property ?

I'm trying to build a single-instance application, but not in the traditional sence. Instead of a simple silent prevention of launching a second application, I want it to send a message to said application so it launches a second mainform in my original process.
(I want some read-only cache (language, style,...) shared, and a few sources like local settings shared, but other then that all resources reside in the mainforms and act as seperate applications.)
(I'm not looking for specific code, more for hints/tips and/or general directions, more specificaly on what parameters do you check process equality, and what method do you use to pass the message? Windows Messages? Sockets? ...)
I am writing a class project application that is loadable from within AutoCAD. This application generates an Excel workbook with extracted data. I am having a problem with Excel closing when finished. It seems the Excel instance hangs until my application is unloaded. I have found the section of code that seems to be causing to hang, but I'm not sure why its hanging to prevent it.
Below is a copy of my code for the class (top to bottom with exception of the FileExistValidation method... too many characters ). The code section that is commented out seems to be what is causing it to hang. If I uncomment that, Excel hangs, with it commented out, Excel closes out in the background.[code]...
I need to be able to run multiple instances of a standalone (3rd party) application. This application prevents multiple instances from being ran from within the application. I need to basically override this.
I know it can be accomplished by hexing the original executable, however I would like to stay away from this method as I'd like for other users to be able to use my application from the get go without needing to hex the 3rd party app themselves or me having to send them the hexed app. Is there any way to achieve this or am I just taking crazy pills?
I have set the "Make single instance application" check box.And when my application version is 1.0.0.0 for example, it is OK and won't load multiple instances.But when I create a new version, for example 1.0.0.1, then I can run 2 instances of my application, when the 1st instance is 1.0.0.0 and the second instance is 1.0.0.1.What should I do to prevent this?

View 2 RepliesI wish to turn on the Single Instance Application choice in Visual Studio 2008 properties. To do so, I must choose "Enable Application Framework". When I do that, my ONLY choice is to choose a Startup Form, not a Startup object. This makes no sense to me. I have a tray application, and I check to see which form I should load, a logon form, or the main form. But since I am forced to choose a startup form, I MUST load the logon or main form to begin with. But I don't want to. I want startup code to determine which one to load first. So then I am playing with making the OTHER form invisible, even if the startup form, but that is a mess.
