View 5 RepliesSomeone asked me to add a function when the notifyicon is doublcliked. I figured that'd be easy with the mousedoubleclick event being available. I find out that then both the single and double will then be called. Well that sucks, I want it to only do the one the user requests. So I tried to get it to work:
Private Sub DblClick_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles DblClick.Tick

i made a border-less form. I minimize it by clicking on a picture-box.
Private Sub picminimize_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picminimize.Click

End Sub

View 13 RepliesA rectangle is painted in Sub pBox1_paint. My intent is to add data to pBox1 via 'drawstring' in Sub btnMoreThan30. The first line of Sub btnMoreThan30 originally included 'ByVal e As System.EventArgs'. The compiler flagged the phrase 'e.graphics' with the error:'Graphics' is not a member of 'System.EventArgs'. I then modified line 1 of this sub as it appears in the code below. The compiler finds no errors but when I click on button 'btnMoreThan30' I get the runtime error,'InvalidCastException was unhandled. 'Unable to cast object of type 'System.Windows.Forms.MouseEventArgs' to type 'System.Windows.Forms.PaintEventArgs'. How can I draw lines and strings in a picturebox from a button_click sub?

I use a single instance in my application. What if I give command line arguments to the exe of my program, so I can be selective in what was given command line in my program, but still single instance?
Example:
test.exe /show
When the command /show, then my program will
Form2.Show
Form2.BringToFront
I have a single instance database app that emails out notifications. I would like to add a link in the emails that when clicked would open up the app and go to the section of the program that its supposed to go to. I implemented my own URL protocol so that links starting with my codewords get passed to my EXE. So far so good. I then parse the URL and pull the keyword and identifier out to open that section of the program. So if a user clicks a link like this:
MyApp:LoadCompany?ID=323
My application will start, it will grab the arguments (LoadCompany?ID=323), pass this to my load company routine and then load up company ID 323. Works great.
Now the issue is if the program is already open I still want the links to work but since it's a single instance app it just closes the second app. How can I add something ot the app to watch for this or receive a message from the second app? I know I will need to check status of what I'm doing and make sure things are saved, check security, etc but I can get all that done easily enough. I've found some examples online but none really did what I wanted them to.

When the user clicks the Exit button it closes the forms and if there was an open file it asks the user is they would like to save. But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes. How do I write the close for Exit to take into account how the [X] works and close the application cleanly?
