i write Me.Visible = false a statement in the load event of the form my application has only one form and it call itself to hide. but when i run the program it doesn't hide itself i put the breakpoint on the statement to see if it even executes or not. it executes fine but no effect what it suppose to do i also have a notification icon added to a form to see it running in system tray.
View 5 RepliesBased on code that executes in Form.Load, is it possible to disable displaying that form after the handler for Form.Load is complete? I'd like to have a commandline switch that disables showing the form, but still runs the application. I've tried this, but it doesn't work:
Code:
If InStr(Environment.CommandLine.ToLower, "/trayonly") Then
Me.Visible = False

I got a couple of issues with my windows application VB.Net. I seem to cannot set the form to be invisible before it shows up for a second, there is no option in the properties of a form and also if I set the form to visible = false before the form is loaded it doesn't work.
So this does not work:
Browser.Visible = False
Browser.Show()
and this does work but the form shows up for a second which I am still not very happy with
Browser.Show()
Browser.Visible = False
Requested were made by Businese Analyst to set the few Main FORMs VISIBLE PROPERTY TO FALSE when the POPUP FORM is loaded.
[Code].....
When the MAIN FORM loads the POPUP FORM, on the FRMPOPUPCUSTOMER-FORMLOAD even, it has to set the MAIN FORM Visible to False.
When FRMPOPUPCUSTOMER FORM IS UNLOAD it has to set the MAIN FORM Visible = TRUE.
How to the coding is to ensure that different MAIN FORM when loaded FRMPOPUPCUSTOMER it will turn the MAIN FORM Visible to FALSE.
I have a form which won't open properly under certain circumstances if a particular Button is set to visible = false. Under the same circumstances if the Button is set to visiblbe = true the form does open properly or if the line of code at a certain place where it is set to either visible = true or visible = false is commented out or not there then the form opens properly. If any one of the 5 phases on my form are turned on then the problem doesn't ever occur but if none of the phases are on then the problem does occur. I just found a fix for the situation but I still am not clear about what exactly is going on.

View 3 RepliesI have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

I am trying to make a customer class that will simply make a bunch of controls (hotspots) Visible value = False.
For instance: WinStartSpot.visible = False
Thing is I have roughly 60 "spots" that need to be turned on and off as the user clicks through the program (its a very simple OS simulator) I tried to make a class using boolean return but that failed miserably. how to code a class like that?
A DataGridView in my VB.NET 2008 program contains over 15,000 rows. I loop through the rows, totalling groups of rows and appending 'total rows' and one 'Final total row' to the DataGridView. That works fine. I want to initially hide all rows except for the total rows, giving the user the option to show all 'detail' rows. If i place the statement << dgvTitleCounts.Rows(intRow).Visible = False >> in the loop, execution time increases by three minutes and that is unacceptable.
I see two options: (1) find a faster way of making all rows invisible; and (2) place the total rows in a separate DataSet and bound DataGridView.
I have a couple of textboxes whose databinding's text is set and also readonly is true and visible is false. but when I try to read their values they are all null unless I turn their visibilty to true. The same method is also needed to add a new row to the table (when using bindingsource1.addnew()).

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?

I am stumped on this one. I have a panel (pnlKeyPad) that won't change the visible property when I try to set it to True. But when I try to set the Dock Property to DockStyle.Fill it succeeds. I have tried them in different orders, setting the parent property to the splitpanel and nothing seems to fix it. The panel is on a splitpanel that is visible. The panel is set to visible = false by default.
Any ideas of why this panel won't switch to visible when I specifically set it to visible?[code]...

I know how to turn a control's visible property to true or false, the only thing I don't know is: If I have, for instance, 40 group boxes in which only one is visible, when I click on a button, the first group box visible = false and the second group box visible = true, and when I click on it again, the second group box visible = false and the third group box visible = true, and so on I don't want to write the codes for every controls, since it will be quite time consuming, I want to use fewer codes to achieve this objective,

View 3 RepliesI have a graphics application that uses graphics paths. Code seen below. You can use keyboard characters to display information. When a label is set to visible = false after being turned on for a number of seconds a stray image is generated. The stray images are also sometimes generated when the label is first made visible.
' points p10b, p2b etc are defined elsewhere
Dim GrpPoints As PointF() = {p10b, p2b, p3b, p11b, p5b, p6b, p12b}

I tried stopping the code from running when the label is set to visible = false but the stray image is still generated but just later. If you want more information let me know.The white arrows points to the stray image that is created just after a label that displayed information was set to visible = false

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.
