Hello,
I have an problem with my project.
The project is written by C#, $ used SQLServer 2005 DB.
I also use Web service & Seasar to retrieve A database.
And on webservice side, I have to refer to another package that is built to DLL.
That package retrieve B database.
My problem is when I retrieve B database and update data via dll's function. if it is success, I update A database. But A database cannot update because some error that i cannot control.
How can I rollback the data that was updated in B database?

Is it possible to do ???
And is it possible to fire events from class X (my windows service class) and i would be able to capture these events within my service controlling application ???
Thanks

whould there be a problem if I created a backgroud process in my app that starts an endless loop checking to see if a date and time has been reached. then in the loop pause for x number of hours or days. What is the best way to pause? not looking for the code just the method that would work with the least over head

how the mouse works?
If we move the mouse slower...the distance from desktop it's smaller than distance when we move mouse faster.
I'm interested about relation between speed, acceleration and distance.
any advice..links..tricks...??
thanks in advance

You need to use DateTime.NOw to time the interval between mouse messages and store the points. Once you have locations and times, you can work out acceleration, speed and distance.

Computer mice must convert the motion of the mouse across a surface to the motion of the on-screen mouse pointer. The translation between the physical and on-screen motions is determined by an algorithm (a mathematical, two-dimensional function) that adjusts the rate to allow for both rapid and precise mouse targeting. When the mouse is moved a given distance slowly, the pointer will move a shorter distance than if the mouse is moved that same distance quickly.
I'm interested about algorithm (physical motion vs on-screen motion)

No, windows does that.

All you're able to access is the rate of motion on the screen, Windows has already performed that conversion beforehand. It's not fixed, you can set the rate in your control panel settings

hi
i need an article to compare c# and vb.net applictaions that what exe has better performence ?(not to conapre syntax)
i want to comparing advance diffrence between these two languages in performences and architecture.
thanks

They both compile to MSIL which is then JIT compiled optimised for the processor that is currently available. If I run the same EXE on my laptop and my desktop machine they are unlikely to JIT compile to the same code.

There is a very small number of things C# can do that VB cannot, and a couple of nice things that VB does and C# does not ( but the VB stuff is syntactic sugar, C# can do anything VB can do ). But, as has been said, they both compile to MSIL. The reason people assume C# is better is because VB6 was crap and C++ is still the best performance language, as C# looks like C++ and has C in the title, people assume the same is true in .NET. It is not.

There are a few cases where VB generates less efficient code, e.g. casts from object to int (C# will only unbox the int, but VB does an additional check if the object is a boxed short/long/etc., unboxes that and then does a conversion). Also, VB has some features like late-binding that result in sub-optimal performance if you use them accidentally (e.g. if forget the "As DataType" part in a Dim statement).
However, in most cases you won't notice any performance difference between VB and C#.

i have a managed c++ dll, now i need to call a c# method(not in dll) from the managed c++ dll.
how would i go about it?
i cannot find anything on this topic, everywhere people call from unmanaged c++.
rather have something you don't need, than need something you don't have

Hi again,
you can mix all managed languages in one app, provided you use dll's.
Each dll/exe can contain only one language.
Calling C# from managed C++ is identical to calling managed C++ from C#.

thanks again for your reply.
only problem is that the c# code is not a dll, can i add a reference to a c# exe in a managed c++ dll?

thanks for the help, i added a reference to the c# exe and it works!

Hi,
if your app is basically a C# program that calls a C++ dll, and that dll needs to
call back some method in the C# exe, then AFAIK you need to pass a delegate and use it
as a function pointer (or whatever it is called nowadays) in the C++ part.
Since the delegate type must be known to both the exe and the dll, it seems it must be
defined in the dll (again I dont know the details).
A more general approach would be to create an additional dll that holds the C# code
that is needed by both the C# main part and the C++ dll. Doing so allows the
C++ project (and the main C# part) to add a reference to the new C# dll.

How do I write the code to control a panel's scrollbar using the 9-way navigation button in pocket pc???

I have a web service listener. Once the exposed routine is called from outside it executes some code. The code tracks these responses in memory.
However, a subsequent call to my web service seems to reset the memory.
So for example,
1st call to my erb service
I log some data in memory
return success.
Next call to my web service
The stuff that i logged in memory, is gone.
Is this because by the second time around, the memory is fresh?
How would i get around this if i did not want to use writing to files instead?

Greetings,
I am a test automation engineer tasked to create automated regression tests for our product lines
Our application under test is a C# application that has 2 embedded IE controls. Due to limitations in our test automation tool(Mercury's Quick Test Pro 9.2), we are unable to extract any text from these controls. We need to extract this text in order to perform various verifications.
What I would like to do is create an external C# .DLL that our testing tool can utilize that will return the text from these embedded controls.
My total experience with C# consists of a 5-day training class, so I am very ineperienced with this. I honestly don't know where to begin with this.
Thanks in advance for any help!

I have a complex arraylist containing N types of objects.
public class cls1
{
property string p1;
property bool p2;
property string p3;
property string p4;
}
public class cls2
{
property int p1;
property string p2;
property bool p3;
property string p4;
}
Class cls3
{
property string p1;
property bool p2;
property int p3;
property string p4;
property string p5;
property string p6;
}
I want to bind the grid ROWS (NOT COLUMNS) with the arraylist containing rows of type cls1, cls2, cls3...clsN.
Like one row can contian data of object of cls1 .
Like other row can contian data of object of cls2 .
