I was wondering if it is possible to check if a specific application is running when I open up a form.
If the application is running I want a label to say running, but if it isn't running then the label will say closed.
I would like to close my appliaction and then open it based on a condition.Lets say I have a Lab1.EXE file, I want to close if the flag = True and then reopen it.
If ClFlag = True then
Application.Exit
---Then
RUN LAB1.EXE
Endif

View 8 RepliesMy application commits data to the database via OLEDB and I have no problems with that, but I'd like to be able to have a feature of my application which will enable me to open the database.accdb and display a query/report which already exists within the db.
In the old vb5/6 days this would be as simple as executing msaccess.exe and passing it over the filepath/report name in one string.
This has problems, what if the install path of access if different? Is this even supported in .Net ?

I have a program I made in vb.net express 2008 that used java.utils.zip to compress my work files to a Zip archive that I ran occassionaly to have a backup. I worked fine, but with net framework 4 and vb.net 2010 it doesn't work. So I modified it to use sharpziplib and it works fine if all files on the filter list in the folder are closed, but if I have a file open in OpenOffice writer, my program can't access it and won't create the zip file. The file that usually stays open all the time is my TODO list, that is updated several times a day , so usually gets printed, and updated( adding or deleting entries), without closing it.

My program has many forms that can be launched from the main form, and when launching a form, I need for my program to know whether or not there is already an existing instance of the requested form open before it launches the requested form.
So, if I have form "Search" with button "View" that launches form "Details", I need to know if the "Details" form is already open when the user clicks the "View" button.
Apparently, if I had developed my application as an MDI application intead of an SDI application, I could just do "If frmDetails.visible = True then DoStuff()", but the Details form's Visible property always comes back as False, even when the form is already open. If the form is always being reported as not being visible even when it is indeed visible, what method do I use instead to find out that the form is open/visible/in use?
