Thanks to you.
Since we've tried that, I assume there must be something wrong with our designer, and that we need to revisit the documentation on that.

Documentation certainly doesn't seem to support your suggestion:
The ControlDesigner class provides a base control designer class that can be inherited from and extended to provide design-time support for a Web server control in a design host, such as Visual Studio 2005.
|
|
|
|
|
Moreover, DesignerAttribute cannot be applied to structs. (So says Visual Studio.)

Thanks to the following CodeProject article, this issue is now solved:
http://www.codeproject.com/csharp/propertyeditor.asp
What we need for the intended expandable property node behavior is a *TypeConverter*.
This article was excellent, in that it got straight to the point and didn't fail to raise any important detail. Everything worked as intended, first try.
Much thanks to Kodanda Pani.

If anyone is interested (I assume many of us have to deal with this issue), I have discovered that implementing TypeConverter is very sensitive to DefaultAttribute declarations. I'm getting nested nodes without default attributes, but they are dysfunctional. I discovered this in design-time testing, wanting to eliminate the possibility of invoking Reset on the composite property, because the IDE would raise errors whenever we did this. I next thought that since I had declared default attributes on the underlying property classes, that I may as well not declare default attributes on properties of these types... but no... the TypeConverter implementation falls apart then.

I dropped a PropertyGrid control on a tabpage to use for user settings. I then connected the control to a new class using the propertygrid's SelectedObject property. All of my properties show up fine but I need to know how to capture the event when a property is changed and store it.
Originally I used a settings file but was unable to customize (especially the help descriptions) it to my needs. Hence the new class.
Thanks,
Mark

The PropertyGrid should automatically update your class after its been bound using SelectedObject.

The desktop is not intended to support such functionality.

So reference GDI graphics and/or read articles on this site for your answer. If you have the image, you can assign it to your form's background image. If you need to take a subregion of the source image, clone, copy, or draw that to a new bitmap, and assign that to your background image.

hi all,
i wanna to ask,
that if i have a line and i want to select it
how can i make it seems to be selected(u know in graphics
shapes have their color changed or selected when clicked)

The most simple method is to XOR the color. Off the top of my head I do not know the method to XOR a color. Also you can draw a border around the line. Or you can change the pen to be dashed or some other non-solid pen type.
Pen pen = new Pen(new System.Drawing.Drawing2D.HatchBrush(System.Drawing.Drawing2D.HatchStyle.Cross, Color.Black), 2f);

Hello,
my question today is, how do I declare a method which accepts the reference pointer on an other method as argument.
here is some pseudo code to demonstrate what I mean.
<br />
void humppa() {...}<br />
<br />
void IwantHumppa(????????){...}<br />
<br />
void Main()<br />
{<br />
IwantHumppa(humppa);<br />
}<br />
The "??????????" is the part I don't know and where hopefully you guys can help me!
Thx!
~HUMPPAAA!

delegate void SampleDelegate(int arg1, int arg2, string abc);
private void SomeOtherMethod(int arg1, int arg2, string abc){}
private void SomeMethod(SampleDelegate sd){
sd(1,2,"test");
}
Then in some method
SampleDelegate sd = new SampleDelegate(SomeOtherMethod);
SomeMethod(sd);

I've worked with GDI, but haven't done exactly what you ask... so this is just a hypothesis.
What I would try at first is to take a screen shot of the window as in Alt+PrintScreen. You should be able to easily paint the result from the clipboard to a bitmap or the background image of your application window.

From within a C# application (Visual Studio 2005), I want to programatically iterate the list of GAC Assemblies used by the program, and view the Assembly versions. Can anyone provide me with information, and/or a link, that will help me perform this task?
Thank you...

Hi,
I am clueless about how to perform a virus scan using my symantec antivirus, i.e. i am developing an email client, I need to scan virus first and then send.
Thank you!

Is there a way to make the Save File Dialog have an uneditable (so they have to stay in that directory) directory path or do I have to create a dialog from scratch to do this?
|
|
|
|
|
AFAIK, you have to create your own dialog to do this.

If any 1 has any clue about it, please let me know
Thank you!

What do you mean by "it opens up a window for each of the selected items"?? You didn't give any information as to how you're using this context menu or in what application...

Hi Dave,
I registered an entry in the registry for .txt files so each time when right-click is pressed in the menu my menu entry is also present.
My appliction is just a test that windows is passing me the file paths of the selected text files.
Application opens up a console window and displays the path passed by windows as argument.
Now when I select multiple files, it opens up multiple console windows displaying path of each file in each console window.
Thank you!
