The wrapper is effectively generated as a .NET stub code. This means that the compiled DLL will contain the code that is necessary to call into the COM DLL.
Arthur Dent - "That would explain it. All my life I've had this strange feeling that there's something big and sinister going on in the world."
Slartibartfast - "No. That's perfectly normal paranoia. Everybody in the universe gets that."

That would be ideal, to have the compiled DLL contain all necessary components implement the interface defined in the COM dll.
But when I add the reference to the com DLL (in my case its called xesession.dll) and write my C# code implement against it and build the solution it creates a file called interop.xesession.dll . Isn't that the 'wrapper' ?
Or do I need to turn off 'interop' or something?
thanks again..

And also, if the interface I'm implementing in C# is to be instantiated and used by a non .NET (VB6) application will my VB6 app recognize the object even though the object is managed and the VB6 app is not?

Hi all,
i am using the API :
[DllImport("user32.dll")]public static extern int GetCaretPos(ref Point lpPoint);
what i'm trying to do is the show contextMenu above the KB cursor.
it's working good with MSN messenger and Notepad (the function returns the cursor's possition in the active window)
but, in other programs like:MSWord,Yahoo messenger it returns(X=<the currect="" x="" location="">, Y=0)
how is it possible?
Sincerely,
Ran.

if (hFocus != IntPtr.Zero)
{
hFore= (IntPtr)GetForegroundWindow ();
AttachThreadInput((int)GetWindowThreadProcessId((int)hFore, id),
GetCurrentThreadId(), 1);
hFocus = (IntPtr)GetForegroundWindow();
Point mypoint=Point.Empty;
GetCaretPos(ref mypoint);
Console.WriteLine(mypoint.ToString());
ClientToScreen (hFocus, ref mypoint);
return mypoint;
}

Don't use the pre tag on the message. The font isn't that easy to read, and the text doesn't wrap.
After you insert a record, use the query "select @@identity" to get the id that was created for the record.

b { font-weight: normal; }

thanks Guffa for the reply ill check it out 
Sorry for the pre tag
|
|
|
|
|
yes,
Rows = table.Select("select @@identity");
in Sql Server
INSERT INTO jobs (job_desc,min_lvl,max_lvl)
VALUES ('Accountant',12,125)
SELECT @@IDENTITY AS 'Identity'
@@IDENTITY is SQL system variable
datatable have very SQL method , So you think dataset like a small SQl server
Agree ...

I am just starting to look into MSBuild. Wonder if anyone could offer any pointers? Would the following be an easy thing to do?
- Build a set of .CSProj files, in dependency order
- Specify the 'reference path' as to pick up the correct dependies
- Override what is in the project file and output to a build folder.
Would MSbuild fully support this?
Thanks in advance

I have a need to grab the mouse and move it to specific locations in a target window, approximately once a second.
Each time I grab the mouse, I save it's current position and put it back when i am done. However, I do not want to grab the mouse if the User is currently using it (like when pressing the left button for a drag) in some OTHER application as that causes undesirable effects and is a MAJOR irritation to the User.
I think I need to get information about the mouse buttons that is system-wide in scope (not form-specific nor thread-specific).
I hope that makes sense.
Any ideas?
Thanks.

You might use the MouseEnter and MouseLeave events to keep track of
the presence/absence of the mouse in your application.
Remark: some special care may be required when you also use menus, since
clicking them seems to interact with the normal Enter/Leave sequences.

thanks for response ... but that does not help ... i need to know when the mouse is IN USE, not when it has left MY form.

OK  , sounds much like activity detection; this is used e.g. by screen savers,
so I suggest you look at one of the many screen savers on CodeProject.
Furthermore, you could look at a "global system hook" (as explained in
http://www.codeproject.com/csharp/globalsystemhook.asp[^]).

hi. I want to share a file (.cs) in two projects. I am writing server-client type seperate project s, they run at the same time, I have classes that I use both of them. I want to share a .cs file say sharedClasses.cs and want it to be compiled from the new code file. normally without this, I always copy the same code to other project's sharedClasses.cs..
|
|
|
|
|
I would make a project for main functions, compilled to a library, and one project for the client and server type, but in one solution. First compile the class, and after that the client and server.

I'd put the files you want to share into a dll

In Solution explorer, chose the projet you wish to shsre the file TO., right click and choose add->existing item.
browse to the file you wish to share and select it. BEFORE CLICKING THE ADD BUTTON, click the down arrow on the right of the add button, and choose "add as link" from the drop down. The selected file will now be shared to your project, rather than copied to it...
Who'd a thunk it - button cross bred with a combo. Took me for ever to stumble across that non-intuitive POS.

I have afew questions regarding the tab page control:
1) I have to force the user to not change the page untill a database is loaded. I used the invalidating event to force the user not to change focus untill the dataset is loaded. the only problem is:
i don't kow how to put the condition: dataset.tables.count!=0 is right??
and
does the validating event actually worg between tab pages?
2) I want certain tab pages to be either disabled (I mean to appear on the tab control disabled, not all the controls on it to be disabled) or invisible(likevise)
how do i do that?

1)If you use .Net 2.0 there is an event called DataSet.Initialized, and a property called DataSet.IsInitialized. When the Dataset finishes initialization, the event fires, and the property is set to true.

2) I don't think I caught up with you, but if I got you right, then you don't want to hide, nor disable the tabpages and the inner controls, yet you still don't want to allow changing the current page. You can handle TabControl.SelectedIndexChanged event, and check IsInitialized in it. If it wasn't true, revert the selected index to the page you desire.

1) you may write :dataset.tables[tablename].Rows.count!=0
2) tabpagechange event can handle this.
Sorry ...

|
|
|

yes, but how do i get the page(index or name) from wich the index/name was chaged? the tab control doesn't have a last selected page or last selected index property.
Another problem is the fact, i think, the tabcontrol selected index changed occurs after the tabpageenter event.
