I have a form that I call from another form. Whenever I call it using form.showdialog() or form.show() the form appears, but it never executes the code that is in the form_load sub.
What's the deal? I call other forms in the same manner and they all load and execute the load code without issue.
I have a piece of code like...
If FRM_LOADED(lngID)
Then
FRM_X(lngID).WindowState = FormWindowState.Normal
[Code]......
and in VS 2008 the form (FRM_X ) loaded and invoked the Load method. After upgrading to VS 2010 the same code executes and displays the form but the Load method isn;t executed.
I migrate a project from vb6 to vb.net.In vb.net project form's events are fired randamly. I mean form_Activated event are fired first after that form_Load event are fire. and this events are fired more than one time.what condition form_Activated event fired before form_Load event.
View 2 RepliesCreate a Visual Basic project with a Form that displays a seating chart for a small theater. Assume that the theatre has 25 rows and each row has 10 seats. The following image shows the completed main Form for the solution.
Write statements in the Form Load event to instantiate an object from the splash screen form and then display it as a modal window. Write the statements so that when the main Form loads (after displaying the splash screen) it will dynamically create the 2-dimensional array of CheckBoxes on the Form. The CheckBoxes should be created inside a scrollable Panel control instance. Above the scrollable Panel control instance display the column numbers (1 to 10).
does anyone know why the form load event being completely ignored/bypassed during loading the app? The form loads but none of the code in form_Load sub being executed (yes I tried putting a break inside the sub and it didn't trap)
View 13 RepliesI have a problem concerning the Form_Loading event: When I want to load a new Form (ImageDisplay) the ImageDisplay_Load Event is not executed first.
Instead it runs through the global variables definitions and then executes a Private Sub called numericupdown1_changed.
The numericupdown1 field is part of the form I want to load and has not been touched.
That is my calling sequence:
Private Sub Dispalydata_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Dispalydata.Click
Dim myDisplay As New ImageDisplay

The strange thing is that for other forms in my code it works well and starts with the form_load function.
I am having a problem in Form_Load. When the following code executes the form pops up with out executing any further code: Me.TblAssetsTableAdapter.Fill(Me.ITP400_IP3_ADataSet.tblAssets).
I am trying to use Form_Load to populate values in a ListBox control from an Access database table.It appears the problem was in the Compile settings. It was the 'old' problem of using AnyCPU on an x64 machine. I changed the Compile setting to x86 and the problem disappeared.
I am using visual studio 2005. I want my form should be editable, when i am pressing some function key. Like, when form load, no field should be editable. When i will press "Ctrl + N" or "Ctrl + F2" Key then only form should be editable. Is this possible?

View 2 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 9 RepliesI was under the impression that there was not much difference between Sub New() and Form_Load. However, I found one weird bug...Add a combobox and a label to a form, and the following code:
Public Class Form1
Private mstrOutput As String = ""[code].....
The label text shows that the value of ComboBox1.Text changes between Sub New() and Form_Load.Is this meant to happen?
First, Im new to VB but have been programming for 20 years.
Ive been creating an application that starts with a form that has 4 text boxes with corresponding search buttons.You key something in to one of the text boxes and click the corresponding search button and it would execute the code in the button click event. It worked.
Ive done something though to make it not work.When I run it and click on the button it doesnt run the click event.
If I double click on the button in the development mode, it should, I thought, go to the click event in the code but it doesnt.It creates a new click event with the same name as the original but with a_1 appended on to the end of the name.
I have created a class, in which button control is created programatically. The click event is added using "Add Handler". Now I create an instance of this class whenever I want to create a new button. The problem with this design is that in the ButtonClickedevent I have to write swtich cases to provide different implementations as per requirementI don't want to perform this functionality in this class. Is there any way in which when I click on this button the method from other class gets executed? may be inheritance,

First, I launch a website in Internet Explorer from VB.net and automatically login the user with ther username and password. As soon as the username and password fields are automated, I send "enter" to the website so it goes to the next website. This part works perfectly. However, my problem is that i want to send a mouse click event, which i have already written, to click a hyperlink on the next website page. I tried a few different things, none of which worked. My program is automatically logging in the user and doing the mouse click event at the same time. I have tried to use the "sleep" command, but the mouse click event is still not executing after the second webpage loads. I have tried using nesting "If, then" statements and that has not worked either. Does anyone know how to make sure the webpage fully loads before executing a sendkeys routine or a mouse click event? This is my code thus far:
If (Search.ComboBox1.Text = "IWR") Then
BlockInput(True)'this disables the mouse and keyboard
Dim IE As New Object

There are no errors, everything is just executing all at once instead of letting the second webpage load and then executing the mouse click event.

View 18 RepliesI have been playing around with VB for a while now, but still need to consolidate some thoughts. I was wondering if anyone could answer this..... Whats the difference between say Form1_Load and Public Sub New() on form startup? The reason i ask is i normally add calling subs to the form load process, but can you add any startup calls to the Public Sub New(), and if so, what is the advantage?

VB2008: use a BindingSource on numerous textbox fields. The form loads ok and all of the binding is working fine. My problem is that I need to set certain form defaults based on the incoming data prior to showing the form. I cannot find a form event that fires after the data is bound, yet before it is displayed. I tried Form_Activated and several more. The bound fields are still showing zero-length strings. This wasn't a problem in VB6. Can anyone point me in the right direction?
View 1 RepliesI am trying to write a graphing program that will draw on/in a picturebox during the form_load event. It works if I connect the code to a button event and click the button but the exact same code in the form_load event seems to do nothing.

the dashed line indicates the point of termination. the for-loop is simply not done. i tried it with stop points and the last point it stops is the ReDim-part. this can only mean, that the ReDim-Command forces the program to leave the method. but the for loop is never done afterwards.

The application I'm writing requires the user to select a certain directory on their hard-drive (a game directory), which is saved to the Settings. If the directory is not selected, my application can't work. So, when the program starts for the first time, the directory setting will not be present, and I want my application to ask the user to select the correct directory before the application starts (the main form is shown). I used the following code in the Form_Load event of my main form:
vb.net
If My.Settings.WolfPath = String.Empty Then
MessageBox.Show("Please select your root 'Wolfenstein - Enemy Territoryetmain' mapping installation.", "Select W:ET Path", MessageBoxButtons.OK, MessageBoxIcon.Information)
[code]....
It looks pretty complicated (probably too complicated) but I wanted to make sure that the user cannot continue until a valid directory has been selected. So when the user cancels the folder selection, my application should end. If the user selects an invalid directory (it should end in "etmain") it should display a messagebox and show the folder browser dialog again. It should keep doing this until the correct path has been chosen.The problem occurs when an invalid directory is first chosen. The messagebox does show, but it shows behind all other applications! It took me a minute to figure that out, because I could not find my application anywhere, but Visual Studio still said it was running... After finally finding the messagebox behind everything else, it seems that now everything comes up behind everything else! When I click OK on the messagebox, the new folder browser dialog also shows up in the background, etc, etc. If I then choose a valid directory, the application loads the main form in the background...
I thought at first the problem would be the fact that I am running this code in the Form_Load event. A better place perhaps would be a Sub Main() from which the main form would be loaded explicitly (Application.Run(mainForm)). However, I can only select Forms as the Startup Form. If I disable the "Enable application framework" checkbox I can select the Sub Main() as Startup Object, but all the visual styles are lost...?
