Hi,
first of all, do NOT you this.CreateGraphics(). Just use e.Graphics available from parameter like this:
protected override void OnPaint(PaintEventArgs e)
{
using(Brush brush = new SolidBrush(Color.Magenta))
{
e.Graphics.FillRectangle(brush, rect);
}
base.OnPaint(e);
}
second of all, interval is in miliseconds so this timer.Interval = 10; will redraw whole form 100 times per second. It may flicker even on good computer.

Thank you so much.
changing it to e.Graphics fixed everything. Also, it went from extreme flicker (practically disappearing for a full second or two) to incredibly minor flicker at a 10ms interval.

Hi to all,
I have a program that recieve a txt file and work the text in it.
The problem its that wend i take the text from the file to a string hi have unrecognized characteres in the positions where i should have accent letters like á or ö for instance.
So i tink that the better way is to encode the txt file in utf8.
Is there any way to do it in the code lines?

StatusStrip don't process mouse clicks if parent window is inactive.
I have an application with two winforms, one which has a StatusStrip object. The StatusStrip object has a couple of buttons with mouse click handlers hooked up.
If the window with the status strip is the active window, the mouse click handler get called when user clicks on a button on the status strip.
If the window with the status strip is not the active window, it takes two click on a status bar button to get the mouse click handler called. The first click only activates the window and do not result in a call to the click event handler.
Anyone knows how to fix this? How to get a status strip to fire events even if it is in a nonactive window so user don't have to click twice?

Hello, all you smart people.
Short version:
In Visual Studio 2005, the 'Data' menu item at the top of the screen keeps disappearing after I attempt to show the existing data sources, or add a new data source. Any ideas?
Long version:
I'm encountering a rather frustrating issue in Visual Studio 2005, SP1. I am creating a Visual C# ASP.NET Web application, and I want to add a Data Source to the project. Now, when I first create the application, the 'Data' menu is available at the top of the screen, with the two sub-menu items 'Show Data Sources' and 'Add New Data Source'. The respective icons also appear in the Data Design toolbar.
However, when I click the 'Show Data Sources' icon, or the 'Show Data Sources' menu item, the Data menu item disappears, and the Data Design toolbar icons become disabled. No matter what I try, I can't get the Data menu item to re-appear. If I completely shut down VS 2005, then launch it again, the Data menu is back. But the same behavior exists (i.e., it disappears if I try to use it). Similarly, if I click the 'Add New Data Source', I am allowed to go through the process of adding the data source. But when I am done with that process, the Data menu makes a hasty exit, and I can't even view the data source I allegedly created.
Any idea what is happening, here? As far as I know, my installation is fine. This does not appear to be the issue of the 'Data' menu disappearing when the context of programming calls for it to disappear (for example, when editing code).
My Google-Fu has failed me on this issue, so I am calling out the big guns (RE: this forum). Thank you in advance to any and all those who read this, and a special thank you to those who respond.

Don't cross post it is an abuse of the sites resources. Also neither of the forums you posted this in is the correct one. Good luck

I have a windows app and on form_load i am calling a funciton that is building a list but this function gets called on other ocassions also (when there is change in data (i.e. add, update or delete)). I want to raise an event when I have the item.Name available so I can populate the drop down box with the item names.
So essentially I want an OnItemLoad event to be fired and when its fired I want the drop down box to populate the items.
for (int i = 0; i < Category.Length; i++)
{
#region This section needs to be replaced by the event
if (populateCategoryDropDownList)
{
ddlCategory.Items.Add(Category[i].CategoryName);
}
#endregion
...
txtControl.AutoCompleteCustomSource.Add(temp);
...
}
I have tried working with examples available on msdn etc but it gets soo confusing! this seem like a very simple task but I just can't seem to figure it out. Please help !

What is "item.Name"?
Do you need an event, or do you just need to call the method that builds your list from other events, like Load?

Sorry, Item.Name = Category[i].CategoryName
Item being a drop down list item.
This can be done with a call to a method but there is some other stuff that can be accomplished once I have a specific category available. I tried to omit the details out to keep the question simple.
But for argument's sake, for each category there are several other child records that need to get processed. Some of them are shown on the UI and some of them are more like calculation type results.
I thought using event would simplify the process and would also increase the performance (not sure if this is true) by completing the task on a separate thread.
Thanks

Events are an implementation of the observer pattern. They are used to notify an interested party that something has happen to an object that they have expressed an interest in knowing about. Events don't increase performance, however, can certainly decrease it if not used properly. From what I can see from you description you don't need to use events.
You should also do more research before trying to use a technique you are unfamiliar with. Learn when and why to use, and when not to use it.
