Hello, does anyone know how to create a texture bar in AxMSChart?
I defined a TextureBrush, but I cann't change the brush of the bar going to use the TextureBrush.
After that I am going to turn it back to normal solidbrush.
Please help.
Thanks!;)

I'm trying to make a custom control that shows a collection of images (and more but I'm not having a problem with the other code), there's two problems I'm coming across:
Resizing: When the control is on the form it will redraw properly when being resized smaller than it was originally drawn as, but resizing any larger will stop it redrawing properly. I've added code on the Resize event properly, and I can see it works when I resize the control smaller. I think this might be a .net problem since I've seen this before, just can't remember where...
The more critical problem: Array Property. My control has an array of "Tiles" as a property, these Tile class currently holds two properties "Name" and "Thumbnail". The control arranges and draws these thumbnails on the control. When I put the control on a form and add Tiles via the properties window of the control in the form designer, it will add the tiles fine and draw them to the control. However when I run the program or close the form designer these tiles disappear  I have a feeling I need some code to maintain the data but what? It's all rather confusing

Don't know about the redraw issue, but as for saving properties, put this attribute in front of them: [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
I'm in the high-fidelity first class traveling set.
And I think I need a Lear jet.

Ok just took a look at those pages and they've completely gone over my head. Are there any simplified references on that? Like an explanation of why I need a Component class, where to have it, and how to use it in relation to a custom control....

How can i use this as image for a noborder form?

Hi I'm reading data from a file with a double stored in it. What I want to do is cast the double from a string to a double. The thing is that string looks like this "37.05" instead of this "37,05".
Now what I want to know is if it is ok to just exchange the . for a , or would this cause a FormatException on some other system?

The best way is to provide a IFormatProvider from the culture in which your App is running this makes sure you have international support.
Eg,
Double.Parse(N, Thread.CurrentCulture.NumberFormat);
A short term fix is to pass a number style argument to Double.Parse, with the current decimal seperator in your case "," in some other countries ".", look up MSDN for details on numberstyles, basic format is
[ws][sign]integral-digits[.[fractional-digits]][e[sign]exponential-digits][ws]

Thank you I will try that.

Can anyone offer any suggestions on how to make a GroupBox, or alternatively Radio Buttons within a GroupBox, ReadOnly, similar to the ReadOnly mode in Text Boxes. I dont want to use the Enable property has this makes it difficult to view. I want to have a form with several controls where the user can edit the content of controls depending on his privileges. If the user doesn't have the required privileges, I do not disable the controls but set them to ReadOnly. This way, the user can still very well read the texts in the TextBoxes, because their text is still painted in black.

How about creating a derived class with a readonly property, and when it's true, you ignore all mouse clicks ?

If you vant to do it read only in the chech_canage event handler, set it's default value, eg.: if you want it to readonly and checked than in the handler :
if(!checked) checked=true;
I know it's disgusting, but somtimes disgusting thinks is the best way. Like Assembly it's disgusting and powerful

I am trying to make a form in outlook that I can manipulate to add controls to. I see that each item type is strongly typed and cannot see a generic class that I could inherit from as such. I thought that the OlItemType.olNoteItem would be a simple type and would like to be able to manipulate the form just like it was a windows form. Can anyone point me in the right direction?
I can create this note by doing this...
NoteItem objNoteItem = (NoteItem)applicationObject.CreateItem(OlItemType.olNoteItem);
Now I would like to change the interface of objNoteItem and place buttons and text fields and listen for events.

namespace NeuralNetwork
{
public class NeuralNetwork
{
public void SaveXML(StreamWriter SW)
{
SW.Write("<Neural Network>");
}
}
}
another file:
namespace NeuralNetwork
{
class Program
{
static void Main(string[] args)
{
NeuralNetwork nn = new NeuralNetwork(2);
nn.SaveXML(System.IO.File.CreateText("test.xml"));
}
}
}
Why wont this work.
I don't get any error but it doesn't write to the file.

Why does it write zeros?
How could I make it write something?
And I have flushed and closed the file but I forget to write it in the thread.
The real code is huge.

I didn't say it writes zeros. I said it writes "zero bytes" - zero is a count of the number of bytes written. i.e. It writes nothing at all. It is a non-operation.

Supply some actual text to the Write() method.

OK, now I get it...
This is what I got now:
public void SaveXML(string path)
{
StreamWriter SW = new StreamWriter(path, false);
SW.Write("<neural network="">");
//...
SW.Flush();
SW.Close();
}
It doesn't work.
The file is empty.

<i>SW.Write("");</i>
This writes NOTHING. Or is there XML in here that is being stripped because you didn't check 'Do not treat <'s as HTML tags' ?
There's an XMLStreamWriter, I believe.

Yes, that's why it didn't show up.
It write's xml. And that's the point.
The whole func:
public void SaveXML(string path)
{
StreamWriter SW = new StreamWriter(path, false);
SW.Write("<Neural Network>");
for (int l = 0; l < Layers.Length;l++ )
{
SW.Write(" <Layer>");
for (int n = 0; n < Layers[l].neurons.Length; n++)
{
SW.Write(" <Neuron number=\"" + GetNumber(this[l][n]) + "\n>");
SW.Write(" <Output value=\"" + this[l][n].output + "\n/>");
SW.Write(" <Weights>");
for (int w = 0; w < this[l][n].weights.Count; w++)
SW.Write(" <weight value= \"" + this[l][n].weights[w] + "\"/>");
SW.Write(" </Weights>");
SW.Write(" <Dendrites>");
for (int d = 0; d < this[l][n].dendrites.Count; d++)
{
SW.Write(" <dendrite number = \"" +GetNumber(this[l][n].dendrites[d]) + "\"/>");
}
SW.Write(" </Dendrites>");
//this[l][n].weights;
SW.Write(" </Neuron>");
}
SW.Write(" </Layer>");
}
SW.Flush();
SW.Close();
}

OK - given that you posted Write("") twice, and Colin brought it to your attention, you'd understand our confusion..
Your code works fine here - I took out the bit that iterates through the nodes, ran it and ended up with a file that was populated with XML. I have VS.NET 2003.
Is there an exception block somewhere that could be throwing silently, and thus causing the code to never Flush ? Try a flush before the loop that iterates through the nodes and see what you get, then try a try/catch locally in this code to see what the error is, if any.

I looked at wrong file...
Thank you all.

Sorry - had some extra thoughts and edited the reply. Basically, if an exception is thrown while iterating through the nodes, and is caught without notification by the code that calls this function, you may end up with an empty file, as no flush will occur. Try a flush before the loop and if you get the first open node in the file, that's probably what is going on.

I don't have eny exception handling yet...
It works now, so I'm not doing anything with it
