I have a set of tools that I've built as a class library that is hosted/referenced within a main application (ESRI's ArcMap). I'd like to manage the case where a user may pull the pin on the main application while they have unsaved/unmanaged edits pending. I tried handling the Application.ThreadExit event w/ no success. Is there a best practice for accessing the closure of a hosting application in .Net?

View 13 RepliesI'm still unclear as to how this works. The examples in the tutorial don't help very much, and, sorry, I could not make the examples in the previous thread work either and I don't understand the Lost Focus event. What I want to do is fairly simple. 1.) Enter the Test Duration as a string in the tool strip menu item text box in form1. 2.) Make the variable TestDuration equal to the string in the tool strip menu item. 3.) Print the value in a message box after button1 is pressed so I know that it's been captured. Attached is my simple code. This is probably very elementary and I'm sure I'm doing it wrong but I haven't a clue just yet.[code]...

I have alot of experience in working in VBA for excel, but not so much experience in creating my own structures so it's all still a bit foggy. I'm trying to capture the event for when the F1 key is pressed, not just when the form is active, but anytime the program is running. The code below expressing the handling is automatically generated for me in VB Express... But I'd like to change the situation to encompass anytime the program is open. I guess I have to reference events that happen in windows in general, but i don't know how to do it. I think i have to create the even in a class module?

I want to give my end user the abilility to navigate to a web page, and then I need a way for the user to close the web browser control so that I can capture the final url. There must be a way but the obvious candidate (a property named "url" of the web browser control) is not there.

I'd like to create a WebBrowser for the purpose of taking a screenshot of a website. Once its finished it will update a thumbnail image in a ListView. I'd like the whole operation to be done in the background so the UI remains responsive.I toyed with Creating the WebBrowser in a new thread and calling Navigate. I can use a loop to watch for the ReadyState of the webbrowser before I do the screencapture. However it will only continue with the thread if I use Application.DoEvents in that loop. I've never been a huge fan of doing this and would prefer to watch for an event instead. However if I add a handles clause to the WebBrowser it doesn't fire (I tried creating the WebBrowser in the thread, and also tried by declaring it as shared within the class scope).
View 3 RepliesOk, so this is VERY simple to do IF I was working with a regular Textbox control. But of course, Microsoft does not have an "AcceptsReturn" property for a MaskedTextbox Control.
So, if the user finishes typing in the MaskedTextbox control and hits the [Enter] key.... How do I capture that key stroke with this type of control? Also, what if this MaskedTextbox is on a UserControl, not a regular WindowsForm?
I have the following code to control how a form is shut down. Specifically, when they click the red x at the top of the form. My question is, how do I control the minimize button at the top of the page. I want my forms to minimize to the information bar instead. I know how to send it there if I can capture the minimize event.

I've been searching all over and I'm either not searching for the right words or it just doesn't exist. I've got a datagridview (dgv) on a form with some textboxes that are databound to different fields in the dgv's datasource. I want to capture an event if someone changes a value through one of the databound controls so I can mark the row as modified. I've been going through the dgv events trying to capture something, but I can't find anything that fires when a value is changed. The dgv is read only, so the values can only be changed through the databount textboxes.
How to I know if someone changes a value in the dgv? Is there a setting in the dgv that will tell me if a row is modified?

View 2 RepliesI know generally it is not the best solution for a child to handle an event of parent. Take this for example; Mainform loads UserControlOne, UserControlOne handles all UserControlOne needs to. How ever we need a MenuStrip/ToolStrip. MainForm does not need to know much about what UserControlOne is doing. Other then receive some information on a statusbar. Right now events are controlling this.
The menustrip/toolstrip need to be able to speak to UserControlOne, for example when buttons are clicked on the strips. Would you; Allow the child to add a handler to capture the parents event? Move the MenuStrip/ToolStrip/StatusStrip all to UserControlOne so we can ignore all this event hassle? My Major concern with this is now we have taken all the head ache away from MainForm and crushed it into UserControlOne. Any suggestions?

View 3 RepliesHow To Design an Outlook AddIn to capture New Mail Event In Vb .net. I've been able to use code to read the number of unread email messages in an Outlook Inbox. I'm trying to design a plug-in which will be more functional and Catch whenever the SendReceive event is fired. Can anyone point me in the right direction?
I am writing an outlook addin that is supposed to check for any new email messages. I am trying to attach to the send/receive action that occurs within Outlook (Either auto S/R or manual S/R). I have read on a forum online that there is no such event as a Send'Receive, how ever you can use a NewMailEvent. Can anyone demonstrate how this could be done in VB 2005/2008?

In a Windows XP Pro environment, my system uses a mainframe emulator in a window in which a scanning application is running. The data populating the mainframe app comes from various instruments, scales, barcode scanners, etc.. The data inputs are captured by a winwedge type RS232 data aquisition software.
When all the data is processed correctly, the mainframe application sends an "operation completed" message and creates an exclamation system event associated with a specific sound to inform the user.
My goal is to create a MS Access application that would use the Exclamation system event to validate writing the barcode that was just read to a database without further querying the mainframe, creating a local database. I only want to write the barcode when the mainframe application completed and therefore played the sound.
