Hi all

it happened to me a lot - i double click a solution file and open it - change it and find out that its openned twice on my computer.
IN VB6 - you could not open the same vbp twice - how can I do that in vb.net 2005/2008

thanks
Guy

Right click your project in the solution explorer. Select properties and under the "Application" vertical tab - look towards the bottom for a checkbox stating "Make Single Instance Application." Check this and you're good to go.

Hi

Thanks for trying
Iwas not referring to "run my application twice" which is probably solved by your text.
I was referring to the visual basic code - openned twice.

I dont want to open the solution twice by mistake by vb ide

thanks again
Guy

I'm not aware of any IDE options for this, but that doesn't mean it's impossible.


Ranting an idea here -

1) write a quick stand-alone console app
2) disassociate .sln and .vbproj file extensions from the VS selector
3) associate your console app in its place
4) have your console app store off the project's guid or some identifier with an event handler indicating when the owned process closes to release
5) compare the identifier of what's currently being "opened" against your collection to determine if it should proceed
6) if it's a new instance - open it with "Microsoft Visual Studio Version Selector" as normal


Note - this doesn't protect against opening the project/solution multiple times from within the IDE but should mitigate some fat-fingering.
