Hi,
Does anybody know how to make a MDI child dock (or a control from a windows control library) and slide like the toolbox?

Thanks

Newbie Simple question, I can change a textbox ForeColor, BackColor so that say the text is Blue,
But how do I do the same to the datetimepicker?

Although the properties are hidden, they can be changed but they make no difference to the form.

Thanks

Are there "set" properties for the DateTimePicker ? If not, I don't think it's going to work.

Building a .NET User Control base Class

Anonymous5-Feb-03 7:46

I need to build a user control base class for a very large application. I must build a User Control base class, so it can be reused in embedded HTML pages and in .NET Win Forms. I need a set of common classes that will house common functionality for the application (e.g. securityUtilities, xmlUtilities, errorUtilities). Can anyone tell me a good method of doing this?

I have run into a few problems:

1) I can't do multiple inheritances in C#.
2) A user control can't be an abstract class.
3) I have considered building interfaces to combine the classes, but I don't need each class to be a static class.

Can anyone help?

Thank you,
Shane

C# does not support multiple inheritance. You can simulate this through interface inheritance.

But why mark it abstract then?

Interfaces works with instance methods and has nothing to do with static classes.

2) A user control can't be an abstract class.
As I understand it, the controls can be abstract but not in the IDE. When you edit the control, the editor creates an instance of a control, which it cannot do if it's abstract.

Depending how complicated your design is, you can set it to not abstract whilst working on it in the editor, and change it to abstract when you have finished editing it.

Deserialization problem

Hi!
I have the following problem:
I have two application one of them serializes a class(serialization is OK a can Deserialize it in this app too)
The problem is that when I am trying to Deserialize a class from file using the second application, i am getting FileNotFound error.
What can be wrong?
I am using Binary formmaters.
Looking through the serialized file I found that the name of programm i also serialized and probably that name dont let another program to deserialize the class?

The problem seems to be finding that file, not the object serialization. Have you written the right location of the file? have you used "\\" (double slash) in the string instead of simply "\", that's a very common error

No it is not the case, there are two progs, and File not found message is raised during serialization proccess not stream opening, it is also said that he was searching for the program that created that file.

Splitters and WinForms

Hi,

I want to make an app that looks like "Windows Explorer" ( tree view / splitter / my own views).

I have tried with the splitter control, that works fine for a TreeView and ListView, but for my own Windows Forms it doesn't work ( it seems it has to inherit from control).

Is there any way to do that ? How can I use my Windows Forms there, or is there some kind of View class like in the old MFC ?.

Thanks in advance, Greetings
Braulio

Thanks but...

What I want to place inside is not a control, it's WinForm ( I want to have a WinForms, that contains inside two winforms, a tree control, and another form ( that will change, if the user selects another option in the tree).

So I want to have my fix tree control... and 5 differents views..., with MFC I would do it using splitters, and inheriting my windows from the CView class.

Hai

I have One .resx file. I have embedded this file into my project.

Assembly thisAssembly = Assembly.GetAssembly(Type.GetType("samp.Form1"));
ResourceManager rmListImages = new ResourceManager("Images1", thisAssembly);
imageList = new ImageList();
imageList.ImageSize = new Size(16, 16);
Bitmap icons = (Bitmap)rmListImages.GetObject("Image");

When I am running the above code it is showing the following error.

An unhandled exception of type 'System.Resources.MissingManifestResourceException' occurred in mscorlib.dll

Additional information: Could not find any resources appropriate for the specified culture (or the neutral culture) in the given assembly. Make sure "Images.resources" was correctly embedded or linked into assembly "samp".
baseName: Images locationInfo: <null> resource file name: Images.resources assembly: samp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

Can any body suggest how to solve this.

Autogenerating collections

While we wait for generics, I was wondering about collections for a bit. You see, in the .NET Framework library, it seems that Microsoft has created a nice type-safe collection for pretty much every type they use lists for—AttributeCollection, TreeNodeCollection—you name it, they've got it.

So, for my code, which I'm hoping to turn into a really nice utterly perfect DirectX class library that conforms to all the wonderfulness of all guidelines, should I do this? Right now I'm just using ArrayLists, which work OK. However, I could use Chris Sells's really cool tool[^] CollectionGen to generate a bunch of type-safe collections.

Advice?

I've used Chris' Sells tool and I liked it. There are also a few good tools at gotdotnet.com in the user examples. Give them a look and see what you think.

I know how to convert an image object into a graphics object by
Graphics g=Image.creatgraphics();

but how to convert a graphics object into an image object?

Or, how do you save the "graph" that you drew into a bmp file?

You can create Graphics from existing Bitmap (Image) and draw on this Graphics.

// create bitmap
Bitmap bmp=new Bitmap(50,50);
// create graphics from bitmap
Graphics gr=Graphics.FromImage(bmp);

//draw something on bitmap using gr
gr.FillRectangle(Brushes.Green,10,10,30,30);

than you can use Save method of Bitmap
