Is there a way to get the IntelliSense for a lack of better term to work like it does for C#? For example, lets say I want to add a MessageBox to my form. With C# as soon as I get around Mess it's already coming up with the rest of the word, and the same with variables and control names. Just wondering if I'm missing a setting or something some place or if this is just another example of how things are different between the enviroments. Using Visual Studio 2005.

View 9 RepliesI have a textbox with button wired up to a queryextender. My goal is that someone might enter into the textbox a name (e.g. "Dave Mackey") and receive back all relevant results. The problem is that this information is spread across two columns in the underlying database (e.g. FIRST_NAME, LAST_NAME). My code looks like this:
<asp:QueryExtender ID="QueryExtender1" runat="server" TargetControlID="EntityDataSource1" >
<asp:SearchExpression DataFields="first_name,last_name" SearchType="Contains">
[Code]....
If I enter "Mackey" it returns results, but "Dave Mackey" returns no results, I'm assuming b/c it is looking for the entire value in one first (either, but not both together), whereas I want it to return any rows where it finds the entirety even if it is spread across multiple DataFields.

I'm trying to create an application that will allow me to type a search term, corresponding to any field contained in a database, and have the results displayed in a datagrid view. The idea is that the application will display any records that have the search term in any of the fields, rather than just allowing the user to search based on one field only.
I keep getting an error on the dataAdapter.Fill(dt) line. I've tried reorganising lines of code just in case my logic was wrong, but the result is the same. The program just crashes when it reaches this line.
My code is:
Public Class Form1
Private Sub AuthorsBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AuthorsBindingNavigatorSaveItem.Click
Me.Validate()

Public Sub theConnection()

conString = "DSN=XXXXX;UID=XXXX;PWD=XXXXX;DATABASE=XXXXX"

I'm not sure if "Simpleton Technique" is the term used to call "opening a single instance of a form", so please, by all means, correct me if I'm wrong.I opened a child form using the simpleton technique. The situation is like this:
I have three forms (frmUserProfileManager, frmUserInfo, and frmUAC), and all are child forms of the MDI form, MDIMain.You first access frmUserProfileManager using the menu bar. It opens the form using the simpleton technique:
[Code]...
I think maybe it has something to do with the event (MDIMain_Load)? I feel as if the program is only making a child instance of the frmUserInfo once (since the program only loads MDIMain once). And after I close it (frmUserInfo), it loads outside the MDI. Another thing, how do you kill forms that were hidden using .hide()? Is .dispose() applicable?
I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

View 2 RepliesI'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).
I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?
The event handlers in my parent class are never called though the events are raised in the child class.
The Code:
Public Class childForm
Public Event checkboxchangedEvent(ByVal checkbox1 As Boolean, ByVal checkbox2 As Boolean)
Private Sub checkboxchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged, CheckBox2.CheckedChanged

Eg. ""vb.net" timer event trigger on purpose". This application is meant to run at all times to download a web page every minute. To avoid freezing the UI, I read that the best solution is to move the code from a While/Sleep loop to a Timer that will be triggered every minute. The problem I have, is that the user must wait for a minute before the event is triggered:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Interval = 60000
Timer1.Enabled = True
[CODE]...
Is it possible to force this event to occur instead of waiting for it?
I'm trying to execute different code depending on the button clicked (button 4 or 5) on Form1, but when I click on button5 to activitae the code on the Form2's Load event everything is Ok, but when I click the back button to return to Form 1 and click on the Button4 to activate the code on the Form2's Load event again, it doesn't active the Form's Load event, is there a way to form the form load event every time I access it from Form1?

View 7 RepliesStarting from my understanding about Background worker control, I understands that the background worker runs the code in its "DoWork" method in a seperate thread, while ProgressChanged and RunWorkerCompleted events are executed on the main thread.In my senerio, I report the progress and under an specail condition my application displays a message box to the user in "ProgressChanged" method using MessageBox.Show(). and in "Run Worker Completed" event the application finalize some work. There the sequence is important, suppose that the message is of Yes or No type and finalization depends on it. Now when i run my application, the background worker triggers "ProgressChanged", but as soon as backgroundWorker's cancelAsync() is called the program leaves the current "ProgressChanged" method and executes "RunWorkerCompleted" code first.How can i make sure that the "Run Worker Completed" code executes only after the completion of ProgressChanged method.

View 1 RepliesAs you noticed, in the code bellow, the event argument for the form click event has the type "TimedEventArgument".When the event is raised, e.Time holds the time where the form was clicked.Add the missing code in the class Form1 to make this work.You will not change anything to the methods "Form1_Click" or "Form1.Load".You will not use Option Strict On. HOWEVER, you will not do any narrowing or late binding that wouldn't have been allowed if Option Strict was on.You cannot create any new Class, Structure or Module.You cannot cast the EventArgs to TimedEventArg in any way

I am making a function of an application that when a function is called the application will close all processes that are owned by the user and were started after a specific point. My thoughts on this would be to trigger an event in my application every time a process is started and ended, and only if the processes is owned by the user, the event should get information (e.g. the process ID, name, etc) about that process and add or remove that information to/from an array depending on if the process starts or ends. Then when a function is called end all the processes in that array.

I have a Visual Basic Program that, when I enter data into a textbox, uses LEAVE events to update it. However, it will not update until I go to another textbox or press a button or other similar control.This also happens when using the LOST FOCUS event.How can I make the textbox update (be it doing a financial recalculation or some other custom function) happen when the user clicks/tabs out of the textbox and NOT having to click on a button or into another textbox?Do you recommend having a separate button for performing the custom functions?

I have one checking in a textbox Leave event. I will go check whether this ID is already exist in DB or not. If exist, I will prompt MSG box to user.
When I click on Close button while focus is on textbox, this textbox Leave Event will trigger first before Button Click event.
So, the form remains open without trigger Button Click event.
how to prevent this textbox leave event or how can i catch/control this situation?
