I wasn't aware that Microsoft still keep the msflexgrid in the Visual Studio.NET package, or are you adding it in another way?

at first i am also a bit confused,but i think of it for a while and i know it is because i install sql2000 server,and it add the msflexgrid run-time license!but have not install the design-time license!

Under Datagrid.scroll
Have you looked at:
public void scroll( int cols, int rows )
You could then assign both of your Datagrids to this method call.

Hi,
all
I come accross a problem again.
Firstly,I make a ActiveX Dll(myDll.dll) in Visual Basic 6.0. And in myDll.dll there is only one function as follow:
Public Function show ( )
MsgBox ( "Hello world!" )
End Function
Then, I type this command in dos:
TlbImp mydll.dll /out: my.Dll
According the reference ,then I can invoke the method "show" in my C# console apllication.
My C# application(try.cs) as follows:
using my ;
using System ;
namespace Hello
{
public class Activex
{
public static void Main ( )
{
Class1 s = new Class1 ( ) ;
s.show ( ) ;
}
}
}
Finally,I type such command :
csc /r:my.dll try.cs
But errors ocurres, and details are showed as follows:
Try.cs(10,25): error CS0246: The type or namespace name 'Class1' could not
be found (are you missing a using directive or an assembly reference?)
Try.cs(11,25): error CS0246: The type or namespace name 's' could not be
found (are you missing a using directive or an assembly reference?)
who can tell me why ?
regards.

Click the "Set Options" button next to it, not the most intuitive label.

Double DOH!!!!!
You mean the 'Set Option' button is a 'Search' or 'Go' button very intuitive

You can use it like that, however all you need to do a seach is type in the text box and hit enter, at least if you are using IE.

A while ago someone asked how you could set the DefaultValue attribute on a Color property in a control. Well, I finally figured out how 
[DefaultValue(typeof(System.Drawing.Color), "ColorName"] where ColorName is the name of the color you want to use. In my case it was "Control".

hi,
all.
Two source file are showed as follows.
[Try.cs:]
using System ;
namespace g
{
public class Activex
{
public static void Main ( )
{
my myApp=new my();
myApp.SayByeBye();
return;
}
}
}
[ll.cs]
using System;
namespace g
{
public class my
{
public void SayByeBye()
{
System.Console.WriteLine("PPMM is good ,");
return;
}
}
}
then ,I want to add this two files into the same assembly.
firstly:
csc /t:library ll.cs
csc /addmodule: ll.netmodule try.cs
But after I try several times, there is always erros .
Error Message as follows:
error CS2005: Missing file specification for '/addmodule:' command-line option
error CS2001: Source file 'll.netmodule' could not be found
Try.cs(8,4): error CS0246: The type or namespace name 'my' could not be found
(are you missing a using directive or an assembly reference?)
Try.cs(9,4): error CS0246: The type or namespace name 'myApp' could not be found
(are you missing a using directive or an assembly reference?)
who can tell me why??
Your advanced help will be appreciated
Regards.

The library target creates a dll assembly; if you want two sources files in the same assembly compile them in the same command line...
csc /t:library /o:ll.dll ll.cs try.cs

Ok, look at this:
private void Form1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
Close();
}
private void Form1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
Close();
}
When I only use the Form1_KeyPress method, everything works, however as soon as I include my MouseMove method, the *screensaver* won't even load because it is trying to close the application right away. Both are built in theInitializeComponent() method like this:
this.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.Form1_KeyPress);
this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseMove);
Any ideas?

Mousemove fires when the mouse is over an object. Try saving the position of the mouse on the first call, and then checking if it has actually moved before calling Close().
I seem to remember this working last time I wrote a screesaver, but that was before .NET, so its all conjecture

If there is a .NET way to do this I havent seen it yet, and if someone has, please jump in anytime.
In the meantime, this works....
const int WM_SYSCOMMAND = 0x00000112;
const int SC_MINIMIZE = 0x0000F020;
protected override void WndProc(
ref Message m
)
{
if (WM_SYSCOMMAND == m.Msg && SC_MINIMIZE == m.WParam.ToInt32())
m.Result = IntPtr.Zero;
else
base.WndProc(ref m);
}

thanks!but how to use your code!is it in use in other development language or enviroment??
|
|
|
|

It is C#, Just drop it into your Form class.
The intent of my comment "If there is a .NET way to do this..." just implied, *there should be a better way*

it works well!you give me much help!thanks very much!

Hey all, I'm making an app that I want to behave differently when I'm debugging in the IDE but act different when its run normally. Is it possible to detect if it was started from the VS IDE? I know for VB6 there was a howto on the MS website.
Thanks for any help, much appreciated.

You can look to see how many Trace/Debug Listeners are attached, but that won't tell you what debugger/trace is attached.
System.Diagnostics.Trace.Listeners.Count;

Is that reliable?
An old hack from VB is to do the following:
try
{
int x = 0;
System.Diagnostics.Debug.Write(1/x);
}
catch
{
System.Windows.Forms.MessageBox.Show( "Debug");
}
