Forms :: How To Make A Windows Form More Responsive
Aug 5, 2010
In my (VB.Net+VS2008) application, I want to make my windows form (splash) more responsive as there is some complex functionality is performing while loading splash form. Currently when any other application come in front of splash screen and then minimize then splash screen looses its proper visibility and showing some hang kind of state also.
I used Application.DoEvents(), but it doesnt work. I cant use background worker because it doesnt support UI related changes. i.e. Initializing some UI components on shown event of splash screen.

I'm upgrading a project from VB6 to VB2008.I have a routine that clears a combo box, named 'cmbDataTable' which could be on any form. I pass the form and the combo box is cleared.
[code]...
I assumed it would be the same in VB2008 but I get the error.'cmbDataTable' is not a menber of 'System.Windows.Forms.Form'I am working my way through the project, first updating the global procedures - this is one - I haven't written the calls so cmbDataTable doesn't yet exist.

Basically I want everything to look in the same position whether its a small window or big or at least that it has scroolbars if I see it small.

I have a windows form that is set up like one big calendar for the month of may.when you click on May 1st...another form (form2) opens up with some combo boxes and a datagridView on it. What I need to do is on Form 1 (my calendar form)when you click on May 2nd...I want to open a duplicate form 2..the one with all the combo boxes on it.do I have to make 30 duplicate forms ( for 31 days of May)or is there an easier way to make sure that when the user clicks on May2...they dont get a form filled with May1 stuff.I can see that there is going to be a problem as it sits now because I am going to be adding to form 2 some kind of date box, or a date field in my gridview..So I need each form to display the right date?

I created a new windows form application using VB 2010. I added no controls to the form. This is right "out of the box" app created by the VB windows form app wizard. I next added a FormClosed event handler. The handler gets called whenever I click the "x" on the form.Later I needed to close the form programatically in response to an event from an automation client. So I did something apparently farily dumb. I called "Me.Close()" Nothing happens. The form stays up on the screen. My FormClosed event handler is NOT called.The MSDN entry for "Close" doesn't give me a clue as to why this call doesn't work. Indeed, it seems to imply it should work.So I added a couple of lines of code after calling "Close()" since when I stepped across that line of code it appears that no other code would execute. Sure enough, as soon as I step over the call to Close(), I cannot step through any other lines of code.
Then I found another piece of form code while searching around and I found the code had what appeared to be an odd keyword just dangling in the code. The keyword, colored by the IDE as a VB keyword?So I typed "End" into my method and intellisense shows me "End Statement. Stops execution immediately". And it does. But is my FormClosed event handler called. No.I added "Inherits System.Windows.Forms.Form" to see if that had any effect. No change.So how does a form close itself programatically?

I have a small program that works just fine on my desktop (23 inch monitor). I programmed it on this computer as well. My laptop (17 inch monitor) works fine also, however, on a 15 inch monitor the picturebox's are off and not where they were when I programmed it. Also, some forms you can not see the entire form and the bottom is cut off.

I am working on an application and I want the user to be able to enter commands into a textbox, and when they press enter, the command is printed in a rich text box, executed, and the output is printed. For instance: the user types move{file1}, {location} into the text box and this happens:
>command: move{file1}, {location}
>$ moving file1 to location
>job completed
How would I write lines to the rtb and execute commands when the enter key is pressed?
This works, partly.
Private Sub TextBox1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles command.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
RichTextBox2.Text = Environment.NewLine + command.Text
End If
End Sub
it erases everything in the textbox before adding the line... I would also like to be able to make a database of commands, maybe a .dll or something, so that when the user types in something, it checks that database to see if the command exists, if it does it executes, if not, error.

I am currently creating an application which monitors any errors that occur in the other applications I have developed.
One thing that I want to try and do is add a sort of discussion thread into the form, so this allows for each member of IT to add comments/notes about the error that occurred.
Normally I would just use a DataGridView or a ListView, but I would like to have the capability for the comments/notes to be multi-lined so that the user can see what has been written without having to scroll sideways.
