I am using a TreeView Control to view the complete set of folders in Outlook and now I have the complete set I want to prune the ones that don't have the capability of storing mail messages.
What I want to to do is only add those folders to the Treeviw that are of the correct type which means I need to query the type.
I expected to be able to do something like:-
if (currentFolder.GetTypeOfFolder = olMailFolder) {
AddChild(...)
}
but I can't find any reference to a folder type that I might be able to use in this way. Anyone with any bright ideas?
Cheers,
Goose

Hold that thought, just answered it myself!
For those interested, the answer is:-
if (mF.DefaultItemType == Outlook.OlItemType.olMailItem) {
AddChild(...)
}

How do you paint a user control with transparent background?
I have set this line in the constructor: this.SetStyle( ControlStyles.SupportsTransparentBackColor , true );, but now my control has a black background.

Do you also have these two lines?
this.SetStyle(ControlStyles.UserPaint, true);
this.BackColor = System.Drawing.Color.FromArgb(0, 0, 0, 0);

Yeah, I was deriving from CheckBox and i think that was the problem. Now I'm deriving from usercontrol and it works like it supposed to.
Thanks anyways

I'm trying to write a sliding panel custom control. As regards the component sliding etc it is all ok. However, during design mode the V.S. doesn't let me place controls inside the panel. It places them on top of the panel, not into it. Can any one help out on this.
Best Regards

Try deriving your custom control class from System.Windows.Forms.Panel instead of System.Windows.Forms.UserControl
Hope this is what you are looking for...
Greatings,

Did you set ControlStyles.ContainerControl style on your control?
(using Control.SetStyle())

Hi,

The part I like capture is filled with a flash application if that will make it any difference.
Best regards

I'm really struggling trying to bind a Datagrid to a collection of objects. I understand that for each public property of the objects in the collection, a column will be displayed. But I don't want to display a column for all of the public properties, just some of them. And I also want to add columns to the datagrid for things like an image that is associated with one of the properties.
How do you hide columns when binding to objects?
How do you add columns to a datagrid when it is bound to a collection of objects?
Any help would be greatly appreciated!
Thanks

If you databind a datagrid to a list of objects, it will create a column for each property as you said.
However, if you first create a DataGridTableStyle and add to it the DataGridColumnStyle objects that you want then only those columns will be shown.
This can be done directly in the designer.

Thanks! I've just had a look at TableStyles/ColumnStyles and will try it today.

Take a look at ITypedList. Adding it to your collection allows you to create property descriptors. The Datagrid will respect this list. This is more "class friendly" to implementers and they won't have to use table styles to get rid of the unfriendly stuff.

Hi,
Can someone please tell me how can I zoom in and out of an image that is displayed in a picture box control???
Please Help...
Thanks,
E.A.

As far as I know, the picturebox does not directly support such a thing. You would have to write custom code to scale the image from an offscreen source image, then reset the picture box .Image property. You could also write your own simple custom control that intrinsically supports image scaling, which would be more elegant and probably smoother.

Here's an example of what I'm dealing with:
int[] myints = new int { 1, 2, 3 };
foreach(int i in myints)
{
Console.Write(i.ToString()); // WORKS PERFECT.
}
Console.Write(myints.Length); // Displays 3.
int[] newints = new int { 1, 2, 3, 4 };
myints = newints;
foreach(int i in myints)
{
Console.Write(i.ToString()); // WORKS PERFECT.
}
Console.Write(myints.Length); // Displays 4
int[] reallynewints = new int { 1, 2 };
myints = reallynewints;
foreach(int i in myints)
{
Console.Write(i.ToString()); // THROWS NULLEXCEPTIONERROR
}
Console.Write(myints.Length); // Displays 2
So, here's the problem I'm having. When you set an array equal to an array with less elements, the Length property is updated, but there is still a null reference inside the array to an unused array element. You can fix the problem by overloading the Int.ToString() method with a try-catch block to avoid the error, but that's just a patch. How can I reset the array completely, so there is not a null reference to unused elements?

How it display 2 if you got a NullReference exception?

The way I just wrote that, it wouldn't cause the error would occur first. If you put the myints.Length line before the foreach statement, it will display the correct length.

That can't be true. Arrays being reference types, everytime you assign something to myints, the earlier reference is overwritten with the new one. So myints = reallynewints maeks myints point to the reallynewints array now.
The source of your problem is somewhere else. Are you doing something to the myints array after the assignment but before the foreach statement?

Before I answer, how many times does the last foreach loop? Does it loop twice, then give the nullexception? Or does it immediately give the nullexception on thefirst iteration?
