View 2 RepliesInterface And Graphics :: Stop Things Being Redrawn Flicker
Dec 1, 2008I'm having trouble with a football program that I'm writing. I'm finding that there is a lot of flicker coming from the program having to redrawn 36 (Australian football) small circles with numbers in them about 10 times per second (or even more) as the players move.I'm just using basic e.graphics. fillellipse.code in the Paint section of the form. I then use me.invalidate on the timer's tick routine.I haven't touched this graphical stuff for a while and I vaguely remember there being some ways to help this. There are also things like the ground which I'd like to not have redrawn because they don't have to as they don't move. I remember that you can do this but I don't remember how.

View 1 RepliesInterface And Graphics :: Gradient To MDI Form Causes Flicker?
Feb 5, 2009I am using a MDI form and child forms. Now I don't like the standard back colour of mdi form so I got code on the net which paints a gradient colour to the mdi. So far it is working okay.Now the problem is when I load a child form or close it or do a similar activity then it causes flicker in the mdi background. This gets pretty annoying at times and you see the background flicker.
View 2 RepliesVS 2010 Double Buffered Form Still Flicker?
Jan 11, 2012I was wondering if it someone could help me solve this problem. I have a full screen application with a panel in the center which is used to display different user controls and screens when the user uses the app.However, I have a rather large gradient image set as my form's background and it causes the panel to flicker every time controls are added. I find that when the background image is removed the flicker goes away. How can I keep the background image but eliminate the flicker? My form is already double buffered.

C# - Setting ShowInTaskBar = False Causes Flicker When Closing Modeless Form In .net, Winforms?
Nov 24, 2009To recreate this behaviour, you need to create a pop-up form with the following properties:
(1) ShowInTaskBar = False
(2) Display the form with the Show method and loop until the form is not Visible.
(3) In order to close the form when the mouse is clicked out of it, override OnDeactivate, and set visible to False.
Next, create another form that will display the pop-up when a button is clicked:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As Syste
Using pop As New PopUp
pop.Visible = True
[code]....
it also puts a black border around the form. (You'll have to set FormBorderStyle = System.Windows.Forms.FormBorderStyle.None to see this.)what this style does apart from putting the black border round the form?
C# - Stop Developers From Calling System.Windows.Forms.Application.DoEvents()?
Mar 15, 2009We just spent 300 man-hours fixing a buggy application in the field. It all came down to calling Application.DoEvents (re-entrancy problem).This was not caught in design reviews, code reviews.The code was inserted two years ago with the first version; the application was always "flaky" but recent changes exposed the re-entrancy problems to a greater degree. This incident is the second time in our organization that Application.DoEvents caused failures and multi-man hours of debugging.It was discovered in this case by simply noticing the call,buried way down in a complex event handler for an asynchronous task.What do you suggest to prevent this issue from happening again:
Add checkin gates to source control?
Developer training?
Code Analysis rules (why is this not already a built-in rule?)

Calling Showdialog() On A Form - From The Main Form's OnLoad Event Makes The Modal Dialog Go Away After A Few Seconds?
Aug 7, 2009I'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.
I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.
My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.
In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.
I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.
Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox form ):

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.

View 1 RepliesScreen Blanks After 1 Min Of Processing (of Excel File) / Refresh Or Freeze Screen To Avoid Blank Screen?
Jun 29, 2011BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?
