Try something like this:
Bitmap BMP = new Bitmap(@"C:\myImage.png");<br />
Bitmap BMP2 = BMP;<br />
<br />
button1.BackgroundImage = BMP2;<br />
<br />
BMP.Dispose();<br />
System.IO.File.Delete(@"C:\myImage.png");

What's with the flood of non descriptive headers tonight ? Everyone on this forum is asking for help in some regard, probably about C#.
You can capture the mouse, and as it moves out of your form area, you can set the cursor to be null.
Seems nasty to me, tho.

I am retriving Date from SqlServer 2005 but i gets date and time instead that i want only date how should i do it?
|

First, C# is not a useful header, imagine if everyone put C#, the forum would look a little silly, right ?
There is no Date type in C#, only DateTime. You can ignore the time, if you want to.

MyDateTime.Date will return a new object with the time element reset to midnight.
|
|
|
|
|
you can also format the date
Datetime datetime=Person.subscribedate;
datetime.tostring("d");
|
|
|
|
|
you should return only date from sql
you can use convert function
forexample
convert(datecolumn,varchar,101)
it'll only return date not time

Hi,
System.ComponentModel.Design.IReferenceService.GetComponent() is described by MS here:
http://msdn2.microsoft.com/en-us/library/system.componentmodel.design.ireferenceservice.getcomponent.aspx
unfortunately the do not offer example code.
This is what I know:
If a component is sited, you can get the IReferenceService by a call of Site.GetService()...
this works fine.
My Problem:
with C# Express at DesignTime, I always get:
Parent.Equals(myComponent) == true
as a result of this kind of code:
Component myComponent;<br />
IReferenceService refSvc;<br />
[...].br />
IComponent Parent = refSvc.GetComponent(myComponent);<br />
Am I doing something wrong, or is this a bug?
best regards,
Bernd

no one knows?
no ideas?
Am I describing anything unclear?
This is about writing a custom UITypeEditor for replacing the buildin one for a property like this:
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]<br />
public Component Owner<br />
{<br />
get { return this._Owner; }<br />
set { this._Owner = value; }<br />
}
The build in Editor allows choosing components from a toolbox, which are private Fields in the BaseClass of my Form. The result is, that the code added by the designer cannot be compiled anymore, if such a component is chosen.
I am also experimenting with IInheritanceService and IDesignerHost to solve this... I already have a DropDown Editor that works, but till now I cannot filter the shown components properly...
Normal Reflection is no help here, as Reflection does not work on the RootComponent of the Designer...
... I'll check if TypeDescriptor solves the Reflection lack...
So the complete Problem I have to deal with:
How to find out if a Component in DesignMode is a field of the Designers RootComponent or a public or protected (but not private) field of the RootComponents base class...
best regards,
Bernd

I solved the complete Problem, but without IReferenceService.GetComponent()...
... would still be interresting if anyone knows about this...
My solution:
Get the RootComponent with IDesignerHost
Check if the Component you want to use is a Field of the RootComponent by using Reflection:
FieldInfo FI = RootComponent.GetType().GetField(ComponentName, BindingAttributes...);
-> as Reflection on the RootComponent itself is not possible, you will only get Results for Fields of a BaseType
-> you can get also private fields of the BaseType (The code needs ReflectionPermission!)
-> you can be (almost) sure, that all Components for which you cannot find fields, are Components with fields in the RootComponent.
-> all Components with fields in the RootComponent are accessible
-> all private fields you got by reflection are not accessible
best regards,
Bernd

Hi,
How to make a button transparent?
|
|
|
|
|
Set the Opacity property to something less than 100%
|
|
|
|
|
Button does not ve a opacity property as far of my knowledge
|
|
|
|
|
Button control provides the opacity function ???????????????????
|
|
|
|
|

Hi,
I have tested it here, and its working fine.
See I have done the Following to test :
I have created Form as "Form1" and a button as "button1" over it.
Form1.BackgroundImage = TransparentButton.Resource1.Image2;
This just to check if transparentcy is working.
For the Button too I have used a Bitmap.
button1.Image = TransparentButton.Resource1.Image1;
Now in the Constructor of the Form I have set:
button1.BackColor = Color.Transparent;
Also, please set the
FlatStyle as "Popup" for the "button1".
That makes the button transparent, meaning u can see the Image2 from over the
button body.

hi,
Thanks. I don't need any images both on button and form. My idea is to place the button dynamically on the datagrid and when dragged it should be transparent. Hope u got my point
Bye

hi,
if you are using .net v1.1 then you have to set the backcolor of the button to Color.Transparent.
like:
this.button1.BackColor = System.Drawing.Color.Transparent;
and FlatStyle should NOT be "System.Windows.Forms.FlatStyle.System"
It can be either Flat, Popup, or Standard; but NOT System
