In my work, we have a program done by other company, and we don't have the code to change it. This program register a serie of numbers and then if the user whants, save them to an xml file. But if the user forget to save and close the program, it doens't ask if whant to save the data, it simply close and all data is lost. I whant to know if its possible to build a vb.net application that controls when the close button is press and freeze the program or something to remind the user to save the data.
Can I perform an action when the X (CLOSE BUTTON) will be press?ex.If he pressed the X button then a msgbox will prompt and will verify his action of closing the application.
I have been developing my application for a while and need some advice on the closing. I want a code to be run when the close button is clicked but ONLY when it is clicked.
I have dried the form.disposed but that fires whenever the form is closed from the code. I just want it to do it when the close button is clicked.If you don't understand it I will give an example. I have a registation form that is the first thing a user who has not used the app before can see. When they click the close button I want the application to exit through Application.Exit(), however when they have registered the form is closed from the code through
formlogin.show()Me.close()However the Me.closE() triggers the form.disposed event and thus the application exits completely which I don't want. I know I can use the form.hide() but that keeps it running which makes the app more resource intensive.
a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out
What I'm trying to do is have a timer stop ticking after another program is x'd out. (Not really 'closed', but whenever the X button has been clicked). I know it would be an If statement, but i'm not sure how i'd go about implementing it from there.
I've designed an Order Entry System and now I'd like to send an email when an Order has been saved to the Database. I could probably do it from the client machine pretty well, but really what I was looking for was to inform another program running on the server that an Order has been saved into the database with OrderID:xyz. And have that program take care of sending the email. I have no problem designing this second program, in terms of the basics of responding to an event and sending an email. But my question is: how do I raise an event across the network that this other program will respond to?
I am designing a program that will show a reminder form when the computer is shutting down. (The reminder is to go outside and get the Bluetooth gps aerial.) I have tried using the formclosing event, (triggered by windows shutting down) to flash the form up on the screen using windowstate = normal. (At loading, the form windowstate = minimised). This did not halt windows shut down and the form was only on the screen for a fraction of a second before windows shut down. Can I trap windows shutdown until the form btn_Yes has been selected?
I think this msdn library article is talking about this. [URL]
I have looked at the enumprocess api, but this is quite a bit outside my current knowledge level. From what I have read, enumprocess would be suitable as we all run the same program on our laptops and I could check for the change of state of that program. Eg. �OK, program A is closing, the computer must be about to shutdown, so flash up the reminder form.�
I'm new to VB and Windows programming but I do have a fair amount of experience programming at the command line level. A friend is having problems with his laptop. He does a lot of speaking engagements with Powerpoint. His laptop uses the F7 key to toggle the output to his external monitor port to the video projector. The F7 key has stopped doing this. Is there a way to create a Windows program that will do this without using a DOS window? He is not familiar with command line processing and needs something that he can double-click.
I was observing my programs process in the task manager and noticed each action made to the program made the memory continue to rise. So I added a Garbage Collector and since it's my first time using it im not sure if I implemented it right. I haven't gotten any errors but I ran some tests I would like to go over with everyone. After adding the GC I was able to notice a change in the memory my program used- it was reduced.I added the GC to the main forms formClosed event of my application which is used in different scenarios. I also added it to the panels paint events before I tested the program. And noticed a quicker reduction in memory. The Form i mainly use called frmLine1t5. This form calls to the database based on which line to test. Then the form sets the controls that were added in design view to be enabled or disabled based upon the product for that line. This process was easy to implement.I Load each new frmLine1t5 to a collection of the form so people can run multiple tests using the same form. This helped so i didn't have multiple forms for the same type of process. I had to access the forms through a collection so I knew which controls to populate to the correct instance.
I noticed during my testing that I can not add more than 50 items to this collection. The problem is that I remove the key from the collection upon form closing, so I dont know why it has gotten to 50.The test I made Runs two timers. Timer 1 is set to tick every 4.5 seconds This timer loads a new form and tests a new line of product.Timer 2 ticks every 5 seconds and closes the previously opened form.I have it get the GC Total Memory upon loading the form of frmLine1t5 and upon closing the form of frmLine1t5.the results are shown in the picturesThe errors i have gotten occured when ChildForms Open: had reached 50Here are the errors:
[code]...
Possible Causes:I think that upon Form Closing it is taking longer to finish closing before a new form is loaded... But isn't vb.net suppose to finish any unfinished threads? Even if the program is single threaded?And because the form closing isn't "happening" then the key is not removed from the collection.
I am making a program that NEEDS to be password protected, so i made a textbox with a code so that when the user enters the right password it lets you in. But if the user/person enters a wrong password 2X it will kick you out. So is there a way to keep the
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.
I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.
I am trying to build a small program which will allow some one to click on the exit button and the sound will play and at the end of the sound the program will then close. The sound clip is about 3 seconds long Here is what I have:
Imports Microsoft.DirectX Imports Microsoft.DirectX.DirectSound Public Class Form1 Private Dsound As CSoundDevice

I am creating an updater for my program that runs in a separate process. I need it to be able to close the program it's updating before running the new setup, but I do not want to use Process.Kill() because that could cause data loss. How can I safely close another application, as if the user had clicked the "X"?
I would like to be able to close a running program (service) from another program.I know I can use...
Process.Start("C:XxxYyyProg.exe") to start program: - Prog.exe Located at: - C:XxxYyy.
But is there any way to also stop (close) Prog.exe from within another program ? The same one that started it for example...PS I should mention that in this case, Prog.exe is a third party program which I can't alter. It does have an Exit option from a right click.
I made a project on vb.net.Im working with multiple forms.Now,from the main form, I activated the 2nd form.then hide the main form. My problem is when I directly close the 2nd form, my project is till running.I closed it trough the "Close Button" of the form.Any way i could interact with that so I could go back to the Main(first) form when i close it there.
I have a form with a listbox. I have controls on the form that can add items to the listbox with the click of a button. I already have the save file, open file dialogs working properly but I want to add something else that works with them. Lets say I open a file and the listbox adds all the strings from the file. Now, lets say I add something to the listbox and instead of saving the file, I just close the whole form. How do I make my program ask if i want to save the changes to the file when it is about to be closed? (I only want it to ask that IF there are changes to the file).
I am created two projects with two different executive files, which the one are for the normal program to create and the other one is for an update. I want to separate these dialogs.

When I clicked the menu item which are suppose to close the program and load the update form from the update executive file but they did not show up.[code]...
I don't know if this is possible I want my program to execute certain code before it will close even when the x is pressed is that possible. Because its leaving streamreaders open. Timer1 Open sreamreader etc So the timer is set to 100ms to constantly update the data waht happens is its leaving it open when someone closes it during its cycle.
Is it possible to issue a Open CD and a Close CD using VB.net? Are there any examples of code I could see or articles? Thanks for you help, in what seems to be such a trivial matter. (I know though that the simpler the function the more code seems to be
I would like for my program to pause for about 3-5 seconds and then close/exit after pausing. I've used the my.application.doevents() and threading.thead.sleep as well, which may work, but when I add close() after the pause it just closes.
