Re: Speed up Switching TreeView View Type

Don't know if you've solved it yet, but the tree exposes two functions called BeginUpdate and EndUpdate . Put the BeginUpdate before any tree modifications and EndUpdate when you're done. Should do the trick.

Hello Dear SkunkedWorks
For drawing Dashed Line use these sample codes :
dashValues is an array of dash's length.

float[] dashValues = {5, 2, 15, 4};
Pen blackPen = new Pen(Color.Black, 5);
blackPen.DashPattern = dashValues;
e.Graphics.DrawLine(blackPen, new Point(5, 5), new Point(405, 5));

VS 2005 formatting of constructor initializers

I like formatting my constructor initializers like this:

public MyClass(int a) : 
  base(a)
{
}

but for some reason VS 2005 likes formatting them like this:

public MyClass(int a) 
  : 
  base(a)
{
}

It's really annoying and I haven't found a way to prevent it. Anyone have any tips?

Thanks,
Alvaro

VS2005 has alot of autoformating features that you can turn on and off. You can even turn on adding a space before and after a . for a class member. Its one of the many settings, but I don't know why they have some of them. I would look in the options->Customize and see if you can find these autoformat settings.

I've looked but found nothing. I'm hoping there's some undocumented Registry setting or something like that to allow me to adjust it.

I find it hard to believe the Microsoft guys actually like using that convention. I've never seen it before -- what a waste of space!

Thanks,

Selected listview items losing highlight when the lv loses focus

When my listview control loses focus the selected item is unhighlighted but not removed from the SelectedItems collection. How can I keep it highlighted even after a different control gains focus.

Auto Login on Webpage using C#

I have a user that is wanting to automatically log in to some web pages, and I've got most of them doing this, but there's still one that's giving me fits that I'm hoping someone can help me with. I'm writing the code in C#, and am displaying the webpage via the Microsoft Web Browser COM component. The webpage that I'm having issues with is popping up a login box that looks very much like an AD login box. Any idea how I can capture control for this box so I can programatically populate it and hit the "OK" button?

Some more information:

I'm using the old VB WebBrowser COM Component (AxSHDocVw.AxWebBrowser). I think I've narrowed it down to the fact that I need the headers passed to the Navigate method to include the authentication information, but I'm not quite sure how to do this. Does anyone have any sample code (like this for Posting) for the Headers/Authentication?

Thanks

Assigning commandbar images

Hi.

I am trying to build a VS 2005 addin and I want to add a commandbar with a custom image (I am using VS's AddNamedCommand and a satellite dll). It seems that if the image is 16-colored then it is correctly attached to the commandbar. If it is 256-colored, then all I can get is a blank (missing) image. Is there any way to have 256 bitmaps attached to custom commandbars? Thanks.

C# Add-in file synchronisation problem

Hi,

I have some kind of synchronisation problem. I have a C# Word Add-in,
and in it I want to close a file and then delete it. I use code as follows,

// Close the file
pDoc.Close(ref saveChanges, ref missing, ref missing);

// Delete the file
System.IO.File.Delete(pDocStr);

This works fine for a small file, but for a very big file I catch an
exception that says that "the file x.doc being used by another
process".

Anybody any suggestions for handling the synchronisation?

Thanks in advance

Hi Everyone,
I got this code:

if(file.Name.StartsWith(Cont_"))
{
engine = new FileHelperEngine(typeof(Contact));
Contact[] details = (Contact[])engine.ReadFile(file.FullName);
foreach(Contact info in details)
{
txtoutput.Text += info.toString();
}
}
else
{
engine = new FileHelperEngine(typeof(OSFUNOUT));
OSFUNOUT[] details = (OSFUNOUT[])engine.ReadFile(file.FullName);
foreach(OSFUNOUT info in details)
{
txtOutput2.Text += info.toString();
}
}

and wanted to change it to this sort of code:

System.Type type;
if(file.Name.StartsWith("Cont_"))
{
type = typeof(Contact);
}
else
{
type = typeof(OSFUNOUT);
}

engine = new FileHelperEngine(type);

type[] details = (type[])engine.ReadFile(file.FullName); *****
foreach(type info in details) ****
{
txtoutput.Text += info.toString();
}

However the lines with the **** are giving me problems, how do I create an instance of that type?

I could change it to
object[] details = engine.ReadFile(file.FullName);
foreach(object info in details) ****
{
txtoutput.Text += info.toString();
}
however i still need then to cast info to the class I'm working with...how would i do this (type)info doesn't work...

thanks. Smile | :)

This should work.

Array details = engine.ReadFile(file.FullName) as Array;
if (details == null)
     return;
for(int i=0; i < details.Length; ++i)
{
     txtoutput.Text += details.GetValue(i).toString();
}

If you need to access a non virtual method of the object.
Use type.GetMethod("methodName").Invoke(details.GetValue(i), null); or
type.GetProperty("propertyName).GetValue(details.GetValue(i), null);

If I understand what you want to do correctly you should prepare for bad news. C# doesn't compile to a native assembly language, it compiles to an intermediate form called MSIL. MSIL is JIT (just in time) compiled at runtime by the .NET CLR to native code, and this native code will only get generated if the CLR considers it safe.

All this makes C# an extremely bad choice for low level programming - you have no native code, and what you do have is useless without a .NET runtime for the platform you're running on.

I'd recommend a more traditional language like C++ for what you are trying to do.
