Thanks guys...
There is a problem though. I am a newbye and used only to Java
In java there was an event called Window.Closing associated to the closing of the Window (that X in the top-right corner  )
Is there something like this in C# ?
My application was supposed to close when i clicked on that X of the Form.
How can I associate then this X with Application.Exit?
Thanks again

Yes.
In C# you use delegates to register your event handlers. It looks and works a lot like java.
this.Closing += new System.EventHandler(yourClosingMehtod);
where yourClosingMehtod should have a signature like
yourClosingMehtod(object sender, EventArgs e)

I have a main form with a main process that evaluate ever the same proc "MyMethod", ok, but.. this method are store in another class. (ok too)
The Problem.. This "another" class are ever a UserControl,, but i make several copies of thies UserControl and change some layout properties on each one (screen1, screen2)
The unique difference between these screenX are the graphic layout. (This are what i need the graphical properties values)
But,,, How can i do to "switch" the call to MyMethod in order to the "current" screenX object.
The "current" screen is variable.
Of course screen(x) can be 100. I need to do it in a dinamic way.
Here are an aproach to the problem (i wrote this code without test it..)
Note the ????
-------------------------------------------------------------------------------------
using System;<br />
using System.Windows.Forms;<br />
namespace myApp<br />
{<br />
public ???? activeScreen <br />
<br />
public class myApp : System.Windows.Forms.Form<br />
{<br />
public mYApp() {<br />
<br />
<br />
int value = 1;<br />
<br />
switch(value) {<br />
case 1:<br />
Console.WriteLine(activeScreen.MyMethod());<br />
break; <br />
<br />
case 2:<br />
Console.WriteLine(activeScreen.MyMethod());<br />
break;<br />
} <br />
}<br />
}<br />
}-------------------------------------------------------------------------------------
using System;<br />
using System.Windows.Forms;<br />
namespace myApp<br />
{<br />
public class Screen2 : System.Windows.Forms.UserControl<br />
{<br />
public Screen2()<br />
{<br />
<br />
}<br />
public int MyMethod() {<br />
int value = 2;<br />
return value;<br />
}<br />
}<br />
}
-------------------------------------------------------------------------------------
using System;<br />
using System.Windows.Forms;<br />
namespace myApp<br />
{<br />
public class Screen1 : System.Windows.Forms.UserControl<br />
{<br />
public Screen1()<br />
{<br />
<br />
}<br />
public int MyMethod() {<br />
int value = 1;<br />
return value;<br />
}<br />
}<br />
}-------------------------------------------------------------------------------------

There is an ActiveForm property that returns the active form for the app, so you could do.
Form.ActiveForm.MyMethod();
and you activeScreen can be of type Form.

I need to know how to detect the installed version of Microsoft Office (especially Outlook). Cause i have written a class to bypass the "Outlook Object Model Guard" and create addins for Outlook. But i need first to know which version of Outlook (XP or 2002) and which Office service pack are installed.
Does anyone have an idea ?? 
I think using registry is a good solution but is there any best way to do that ??
Thanks in advance.

A few tips :
- More than one Office version may be installed
- Lookup HKLM\Software\Microsoft\Office\xxx\Excel\InstallRoot\Path="c:\....\Excel.exe". Where xxx is 10.0 (XP) , 9.0 (2000), 8.0 (97), ...
- this key tells you which Excel version is installed. It's up to you to check the provided path actually points or not to an existing Excel.exe file. To make sure that the retrieval works fine, combine this key with those from other Office apps, including Word, Powerpoint, Access, Outlook (due to a custom install).
- if you need to know which service-pack is installed, that's somewhat tougher. There are documented papers on the MS site for this purpose, but from my former code I can tell the fastest and easiest way to do so is to check the dll file version (xx.yy.[SSSS].zz) of the Office run-time (mso.dll on OfficeXP, mso9.dll on 2K, mso97.dll on 97, ...)

I want to display a window form inside another form
Please tell me how can i do that.
Thanks in advacne
|
|
|
|
|
I'm not quite sure what you mean faad.
If you are trying to display another windows form, you can use Form.Show().
If you are trying to run an external process you need to look at the System.Diagnostics.Process class and use the Process.Start() method.
Good luck

view the microsoft documents that came with the .Net framework sdk... if you choose to install them...the would be under the start menu. the using referse to a namespace... in this case System (System.Console,ect)it also houses System.Windows.Forms (the form that windows applications are created from), and countless other functions.. i couldnt tell you all of them if i tryed lol. refer to the .net framework guide..for more info... if you didnt install it..you can reinstall or go to msdn.com and seach for the "using" command.

I have a component that uses DesignerSerializationVisibility to serialize collection items to code.
It works great for adding new items to the collection, and rending them as well.
I cannot seem to get them to delete from the code when the parent is deleted.
Example:
I have a variation of the ToolBar, where the button collection is my own extension of the ToolBarButton.
When I add a button, it adds the code to the code file, creating and setting the values.
When I go into the button collection, and remove the buttons manually, the code goes away.
But if I just delete the tool bar, without deleting the buttons, the code for the buttons remains.
Things I have tried:
1) Adding the buttons to the components list.
2) Using the dispose method to dispose of the buttons.
3) Using the dispose method to manually delete the objects from the collection.
The tool bar class extends ToolBar, the button class extends ToolBarButton, and the collection extends CollectionBase.
I have also tried adding the buttons to the base class, but the code is still not removed.
The control seems to work fine, it just won't get rid of the code in the designer. The objects are even being disposed, as the next button I create starts at 1 again, and causes duplicate code entry (which is how I found the problem.)
Any help would be greatly appreciated.

I have a Webbrowser control in a window. When the user clicks a button I want to create a new window (Form) and move the webbrowser control into the new window. Sounds simple!
Trouble I'm having is that when I change the parent of the webbrowser to the new window, the webbrowser stops working. Its kind of frozen, no redrawing or anything. I think this has something to do with OCX, but I know nothing about OCX. When you add a webbrowser to your form in VS.net, it adds some code that deals with OCX.
Anyway does anyone know how to move a webbrowser control to a new window?
(I can't just make a new webbrowser in the new window because of the page that's in it..)

I believe you can't. Stuff like IOleClientSite, IOleInPlaceActiveObject are the reasons why.

OK. Dissapointing, but good to know. coming from you i believe it,

Need to search a C# string for a certain character, much
like strchar does for char arrays... what's the best way
to do this?
thanks

Strait out of the MSDN
String myString = "abc";
bool test1 = String.Compare(myString.Substring(2, 1), "c") == 0;
myString.Substring(3, 1);
bool test2 = String.Compare(myString.Substring(3, 0), String.Empty) == 0;
Or you could just use String.IndexOf()
Which would work something like
String myString = "abc";
int myInt = myString.IndexOf("c")
Where IndexOf() returns 0 - n if the char is found and '-1' if it isn't.
Hope this helps

hi,
I want to get notify before delete file occured in the file system
and to copy the file to other directory,doe's anyone know
how can i do this .
thank's

nissiml,
Have a look at http://www.codeproject.com/csharp/fswatcher.asp[^] it will monitor a selected directory for changes. It may be eaiser to just proactivly back-up and monitor the files rather than try to intercept the file deletion.
Hope this helps

Hi guys
I am wkg on a C# Component which retrieves information from the ADS on Win2k Domain. For some reason, instead of using the System.DirectoryServices namespace, I have to go for the ADS Library (a COM DLL).
To write the code in VB.NET I can go ahead and use the GetObject Global method of VB. as following...
<br />
Dim objLDAP as ActiveDS.IAdsOpenDSObject<br />
objLDAP = GetObject("LDAP:")
' Here it uses the Global GetObject method,
' that specifies the First param as path and...
' NO ProgID as it is Optional Param.
In C#, I cannot use the same global function, hence the alternative, Activator.GetObject can be used. But it does not retrieve the reference at all.
I even tried, Specifically giving the Type param to the Method as...
<br />
IAdsOpenDSObject objLDAP;<br />
objLDAP = Activator.GetObject(typeof(ActiveDS.IAdsOpenDSObject), "LDAP:");
This ends up in giving error message saying that,
A Proper link to the Service may not have been established correctly. How can I make this work, as I must have all my Components in C# only. Porting this part in VB.NEt only for this reason would be infeasible.
Please help me out in this.

You really should be using System.DirectoryServices for this, and only resorting to the ADSI library as a last resort.
The Activator.GetObject is not related to the VB GetObject function. To replace the VB functionality, you can either use the Microsoft.VisualBasic.Interaction.GetObject function, or use a combination of the BindToMoniker and GetActiveObject functions from the System.Runtime.InteropServices.Marshal class.
using System;
using System.Runtime.InteropServices;
public class ComUtils
{
public static object GetObjectFromClass(string className)
{
object ret = Marshal.GetActiveObject(className);
if (null == ret)
{
Type t = Type.GetTypeFromProgID(className);
ret = Activator.CreateInstance(t);
}
return ret;
}
public static object GetObject(string pathName)
{
return Marshal.BindToMoniker(pathName);
}
public static object GetObject(string pathName, string className)
{
if (null == pathName || 0 == pathName.Length)
{
return GetObjectFromClass(className);
}
else if (null == className || 0 == className.Length)
{
return Marshal.BindToMoniker(pathName);
}
else
{
object ret = GetObjectFromClass(className);
UCOMIPersistFile pf = (UCOMIPersistFile)ret;
pf.Load(pathName, 0);
return pf;
}
}
}

Hi Richard,
Thanx a lot for that code! In fact I had tried all the possible combinations of using Type.GetTypeFromProgID and then calling the Activator.GetObject etc. etc. But the most important thing I forgot was about the Binding part. I had been wkg on VC++ with Monikers many a times, I just never thought I would need them here too.
