When the form loads it reads from an embedded resource file that loads the data into variables. It then uses mid(variable,1,1) to load a single value into a textbox. It does this for a total of up to ten textboxes. Sometimes all the values show up sometimes some, sometimes none.

View 2 RepliesI'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?

I cant seem to get VB to focus on a textbox correctly at the moment I did
TextBox.focus()
in the load event but still a button keeps grabbing focus anyway.
I have two forms. Form A and Form B. Form A has a datagrid that is populated from a SQL Database Table query. When a button is pressed Form B is launched that allows you to add a record to the database table. I need for the datagrid to be refreshed and show the newly added record when I close form B and go back to the parent.

I fear that there is something obviously wrong with my code, but I have come across a situation where the Form.Load event is not firing when I create and show my form. The form is not subclassed (as I've seen some problems with that in some searches), and I am not getting any errors thrown when I step through the code in the debugger.
I have a break point set on the IDE-created form load function (which does have the Handles MyBase.Load signature suffix) but the breakpoint is never reached and the form does display and work.The form is passed three arguments in the constructor but the IntializeComponent() function is called before anything else is done.

View 1 RepliesI have a form and initialize some global variables on its Load Event. There is a TextChanged event in one control (a textbox) that uses that value. The TextChanged event of the control is triggered before the Form's Load event even if I do not change anything on the TextBox, it looks like that happens when the control is loaded. Why is it doing it before the form? and what event can I trap in order to assure it's the first thing that happens?
Its as simple as this:
vb.net
Private Sub PackOutMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ActiveFlag = False
[Code]....
My guess is that the msgbox should not appear until the flag is set to true somewhere in the code and then change the contents of txtUser, but it is shown before the form.
I'm looking for an event on a form that fires after Form.Load. Specifically, after the form has been displayed. Is there one?

View 1 RepliesI was having a problem with the debugger not stopping at breakpoints. After a lot of work that yielded no results, I realized that the problem was occuring in the form's load event and subs called from that event.
The problem is that it appears that the load event is not being called. Other startup forms in other projects in the solution seem to be working ok.
what could be keeping the the Load event from working?
I have the following code in the Load event of my form and the 3rd statement obviously fails. My question, why does the code fail and not tell me about it? In other words, it fails and then simply displays the form without crashing. It also doesn't execute my 4th statement.[code]...

I placed this in the form's load event. What I want is for this check to run before the form even loads.If an error occurs, the msgbox comes up and the form is never seen. When I try the code now, the form comes up the msgbox shows. When the user clicks OK the form closes. I tried placing it in the form's designer but the designer tries loading the form any way. How do I get this check to run before the form shows?
I am making the Transition to VB.Net (using VB.NET 2010 express) and I have a simple problem that is driving me crazy. I wish for my Form when it Loads, initialise and then call a sub and do some stuff eg perform a plot. If i place a button on the form and click it the sub works fine.This task was simple to do in VB6 but for the life of me I cannot get it to work in VB.NET. Has the Form-Load event changed in some way with .Net?
View 4 RepliesI have a calculation project with 6 forms. The last form shows all the input and output data from the previous forms. This is accomplished in form6 load event. Form6 contains about 40 controls (mostly textboxes, labels and few pictureboxes), populated in this way:Textbox1.Text = Form2.Textbox3.Text, etc.I am not sure if this is a good practice. I know I can use the DGV, but it does not suit me because of the graphical reasons.

View 2 RepliesI want to develop a program using VS 2010 Pro, VB and .NET 4.0 to run on a Windows standalone computer.The program will be loaded by another program that checks for a text file in a directory.When that file exists, the program I want to develop will be started and it will process the text file.The new program will not have any buttons or dialog boxes, it will simply display the progress of the processing of the text file and then it will simply terminate and exit.
I know I can start the processing by putting code in the LOAD event for the form, but i want to make a new class for all the processing to start from and have the new class perform all of the steps necessary to complete the processing of the text file.Of course this new class will use other classes to do all of the different processing steps.How do I execute that new class from the Form LOAD event?
What I have found is that ifAutoscalemode is set to DPI or Font, the form Load event is raised during the form constructor (sub New). When autoscaling is not active, the form Load event is not raised until the form is displayed (Show method).This change of event sequences caused various errors from code I had in the Load event for various forms because the controls on the forms weren't completely initialized. I have worked around the errors for the most part so it isn't much of a problem anymore but it is forcing me to change some coding habits (maybe not good habits) that I have been doing for years.

what's the best way to stop a form from displaying in its Load event.I initialise a form using the following code:
Dim MyForm as new MyCustomForm
In the Load event of MyCustomForm, I ask the user to select a folder and use that to populate a listbox on the form.folder.If the user presses Cancel instead of selecting a folder, I don't want to display the form. Right now, I just call Me.Close in the Load event, but that still causes the form to briefly appear and disappear in the background. Also do I need to call Me.Dispose?
