It is not .NET i use the visual studio 6

Okay, this is the C# forum (a .NET-only language). Visual C++ is a better forum. My suggestion still applies, however. Start with the method I mentioned.

I would like to be able to add to the View menu in Visual Studio. I am developing a add-in and want to be able to display my own ToolWindow as needed. I am able to add my menu to the top level menu with the code below, but as stated I want this menu Item added below the View menu. I don't want the menu item displayed until the add-in is loaded. The Wizard generated code shows how to add to the Tools menu, but when I try to do the same with the View menu it does not work (CommandBar commandBar = (CommandBar)commandBars["View"];)
// Add to the View menu
object []contextGUIDS = new object[] { };
Command viewCommand = commands.AddNamedCommand(addInInstance,
"ViewAutoReplace", "Auto Replace View",
"View the Auto Replace Tool Window",
true, 53, ref contextGUIDS,
(int)vsCommandStatus.vsCommandStatusSupported+
(int)vsCommandStatus.vsCommandStatusEnabled);
CommandBar barView = commandBars["MenuBar"];
CommandBarControl barControl =
viewCommand.AddControl(barView, 2);
I have tried commandBars["MenuBar.View"] and ["MenuBar.&View"] with no success.

Might help[^].
If you are lucky, you are only facing a proper use of MSO, not a VS.NET extension limitation (which I have faced a couple months ago about the claimed-to-be-programmable Resource view window).

looking for something like a code guidline....
i.e. that a TextBox should have the prefix: txt
TextBox --> txt i.e. txtCustomer
Label --> lbl i.e. lblCustomer
String --> str i.e. strCustomer
bool --> boo i.e. booIsValide
is something like that anywhere available?

I no longer use prefixes for tpyes (str, int, lng, etc...) but I do still prefix controls (txt, cmd, etc...). This helps me see the differences between a control reference and a variable.
The only prefixes I use on vars are scope level. I use m_ for module level vars.

Here is one for the experts. I have searched high and low for a solution, and only found one posting that said:
Sorry, this is a known issue with Owner Drawn Context Menus on Notify Icons. We are examining possible fixes for a future release.
This reply was posted by The Windows Forms Team at Microsoft on 12/12/2002.
I know my ContextMenu works, because it displays properly when I assign the ContextMenu object to the main form. When it is assigned to NotifyIcon's ContextMenu object, a blank menu is drawn.
<br />
<br />
XPMenuItem mnuShow = new XPMenuItem( ... );<br />
XPMenuItem mnuPreferences = new XPMenuItem( ... );<br />
XPMenuItem mnuSeperator = new XPMenuItem("-");<br />
XPMenuItem mnuExit = new XPMenuItem( ... );<br />
<br />
contextMenu.MenuItems.Add(mnuShow);<br />
contextMenu.MenuItems.Add(mnuPreferences);<br />
contextMenu.MenuItems.Add(mnuSeperator);<br />
contextMenu.MenuItems.Add(mnuExit);<br />
<br />
notifyIcon.ContextMenu = contextMenu;
this.ContextMenu = contextMenu;
<br />
Does anyone have any idea how to correct this or if a solution from Microsoft has been released?
Thanks for helping out the newbie,
Ethan

Here is the code snippet again. Sorry the code font was so small:
<br />
XPMenuItem mnuShow = new XPMenuItem( ... );<br />
XPMenuItem mnuPreferences = new XPMenuItem( ... );<br />
XPMenuItem mnuSeperator = new XPMenuItem("-");<br />
XPMenuItem mnuExit = new XPMenuItem( ... );<br />
<br />
contextMenu.MenuItems.Add(mnuShow);<br />
contextMenu.MenuItems.Add(mnuPreferences);<br />
contextMenu.MenuItems.Add(mnuSeperator);<br />
contextMenu.MenuItems.Add(mnuExit);<br />
<br />
notifyIcon.ContextMenu = contextMenu;
this.ContextMenu = contextMenu;

private void WndProc(ref System.Windows.Forms.Message msg) {
int local0;
local0 = msg.Msg;
if (local0 == 273)
goto i3;
if (local0 != 2048)
goto i4;
local0 = msg.LParam;
switch (local0 - 512) {
case 3:
this.WmMouseDown(msg, 1048576, 2);
return;
break;
case 1:
this.WmMouseDown(msg, 1048576, 1);

return;

case 9:
this.WmMouseDown(msg, 4194304, 2);
return;
break;
case 7:
this.WmMouseDown(msg, 4194304, 1);
return;

case 8:
this.WmMouseUp(msg, 4194304);

case 6:

return;
break;
case 4:
this.WmMouseDown(msg, 2097152, 1);
return;
break;
case 5:
if (this.contextMenu != null)
this.ShowContextMenu();
this.WmMouseUp(msg, 2097152);
return;
i3: if (IntPtr.Zero == msg.LParam) {
if (!(Command.DispatchID(
msg.WParam & 65535)))
goto i5;
return;
}
this.window.DefWndProc(msg);
return;
i4: if (msg.Msg == NotifyIcon.WM_TASKBARCREATED)
this.WmTaskbarCreated(msg);
this.window.DefWndProc(msg);
return;
i5: return;
break;
default:
return;
}
}
Anytime it receives the windows message identified by 512+5 (WM_RBUTTONUP), it calls ShowContextMenu(), whose implementation is :
private void ShowContextMenu() {
POINT local0;
if (this.contextMenu != null) {
local0 = new POINT();
UnsafeNativeMethods.GetCursorPos(local0);
UnsafeNativeMethods.SetForegroundWindow(this.window.Handle);
this.contextMenu.OnPopup(EventArgs.Empty);
SafeNativeMethods.TrackPopupMenuEx(this.contextMenu.Handle, 64,
local0.x, local0.y, this.window.Handle, null);
UnsafeNativeMethods.PostMessage(
this.window.Handle, 0, IntPtr.Zero, IntPtr.Zero);
}
}
I guess you've figured out by now that, to attach an owner drawn menu, you just need to override the ShowContextMenu() method implementation.
Good luck!

in order to split a string into an array of lines, I do the following:
myString.split(new char[] { '\r', '\n'});
The problem is that I end up with empty lines. I would like to know if it is possible to avoid that, not having lines with \r or \n at the end, in one similar call. Also, if the user enters empty lines, i would like to preserve them.

Regex.Split(myString, Environment.NewLine);
Should do it, I think.
Or, probably more efficiently:
myString.Replace(Environment.NewLine, "\n").Split('\n');

I'm having real trouble creating a Render Context from a C# user-control or a Graphics object. It should be just as easy as filling in a pixel format descriptor, choosing a simliar format, and setting it. However, although the pixel format gets chosen and set fine, when I call wglCreateContext it always fails, with the Invalid Pixel Format error.
Can anyone help??

Could someone tell me how to get the short filename from a long filename using C#?
Thanks,
Matt

Use the GetShortPathName API:
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
private static extern int GetShortPathName(
[MarshalAs(UnmanagedType.LPTStr)]
string path,
[MarshalAs(UnmanagedType.LPTStr)]
StringBuilder shortPath,
int shortPathLength);
public static string GetShortPathName(string fileName)
{
if (fileName == null || fileName.Length == 0)
return string.Empty;
if (!Path.IsPathRooted(fileName))
fileName = Path.GetFullPath(fileName);
try
{
int len = GetShortPathName(fileName, null, 0);
if (len > 0)
{
StringBuilder sb = new StringBuilder(len);
GetShortPathName(fileName, sb, len);
return sb.ToString();
}
else
return fileName;
}
catch
{
return fileName;
}
}

It is a shame that this is not part of the framework and you have to result to using an old API call for it.

I suppose all we can do is hope for nice updates to the Framework as it ages, I wonder what other functions people are missing from the .NET Framework. I think this might be a survey question in the making.

My guess as that once the OS itself becomes more .NET centered this will also change.
