Event 'OnChange' Cannot Be Found?
Nov 4, 2009I can't quite get a variable to pass between buttons. The variable that I want to pass is totalNumbers and each time a different button is pressed its supposed to subtract a predefined number. Im getting three errors all to do with "Statement cannot appear inside a method body. End of method assumed." What I am trying to do is put a sub procedure inside a button that will be passed back and forth between my call statement and my private sub btnBegin.

Error - The Source Was Not Found, But Some Or All Event Logs Could Not Be Searched
Apr 5, 2012I used to run the following code on WIN XP PRO and it used to work. But why not running anymore on WIN 7:

Log.Source = "Demo Log"

It gives the following error message: The source was not found, but some or all event logs could not be searched. Inaccessible logs: Security.Luai Alrantisi, BSc in Computer Engineering, University of Ottawa 2007, Canada. IT Manager of MTN Mobile Telecom.

View 1 RepliesForms :: CheckedListBox's ItemCheck Event?
May 12, 2008I need to produce a list of checked entries from a CheckedListBox whenever an item changes, but that ItemCheck event gets thrown before the item's status is actually changed so the checked items list is incorrect.I found a forum post telling to use the SelectedIndexChanged event instead, but that won't work if the user checks the item using the space bar.My two alternatives are to :1. Use the ItemCheckEventArgs to figure out what item changed and how. Since the code that gets the list of checked items is a few methods down on the calls hierachy, I would need to pass the event args around (or more likely an homemade representation of its data for consistency).
2. Use a class member boolean to see if I'm in the ItemCheck event handler and set the item's checked state to its correct value before calling the method that does the processing. The boolean is used to avoid an infinite call of the event handler, it would just return without any processing in the case the event handler is in the call stack itself.

Jan 13, 2010I got a combobox, that when the texted is changed, its supposed to run a query to update a field in my database. Here is the issue The event im using is TextChanged, well unfortunately when the page loads, it changes the text when populating the values. Is there a way to make this event wait to fire until after the list is populated? Ive ran into this problem before with datetimepickers, but I was able to offset it with a boolean, but this combobox is calling the textchanged event everytime it adds an item to the list.

Mar 23, 2009On the KeyDown event of the textbox, i need to capture the character pressed and send it to a function which fires a sql query for this character.To get the character i am using Convert.ToChar(e.keycode).However Convert.Tochar converts the keycode to char according to its ASCII value , thus F4 gets converted to "s" as "s" has ASCII keycode of 115.Is there some other way to convert the keycode to character which won't make these wrong conversions as even if i restrict the functions keys there may be problem with other key conversion also.

How To Trigger Event For Any / All Forms That Are Loaded
May 3, 2012I have a project with many forms on it, some of them are dialog forms, some of them are mdi children of my master form. What I need to do is when a user press the ESC button on his keyboard to dispose the form that is working on. either is mdi or dialog form. I know that I can use the event of the form key down and then check the key code if is the esc to dispose the form, but this is not I looking for since I will have to pass from all my forms and create that event. Is there any other way when my master form is load to create my own event for any form load event? And trigger it from there to assigne my custom code for ESC key. So I will not have to pass from all the forms to create that event.

View 7 RepliesForms :: Calling Other Project From Onclick Event
Dec 7, 2011I have a question regarding VB.Net and Object-oriented programming.
I have a solution consisting of two projects.
One project is dedicated to the logic of the application, and one is only to show the Winforms form, and to reflect changes made in the logics project. In other words, when an array filled with various attributes residing in the logics project gets changed, then these changes should be reflected on the form (not that strange in theory).
Here comes the - for me - really tricky part:
I have created user controls, and these are residing in the forms project and placed on the aplication's form. When I click on any one of them, their respective onclick sub gets called okey, but how can I send a message to the logics project from their onclick subs? Basically, I'm not sure on what should be private or not, or possibly how to call the other project correctly. In any case, I can't get it to work.
To sum up: What I need is a line of code calling a class in another project, and someone telling me what should be private, static etc.
Forms :: Can't Change Textbox Text From An Event
Jan 28, 2010I got a Sub which processes a code, and then it does whatever the code said. Example.
Code = "Black" -> Turns screen black.
Code = "OFF" -> Turns off the PC.
And so on.
If I call that Sub from Immediate console, It works perfectly. But if that Sub is called from an event, It does nothing, and usually throws an Exception. I read somewhere that I can fix this by using Threads, but I don't understand how that can help and make it work.
