Hi,
I need to implement a timeout expression.
Forexample like in services there is:
TCPIPServiceController.WaitForStatus(ServiceControllerStatus.Running, new TimeSpan(0, 0, 10));
Where it checks for 10 sec whether the service has reached a running state, else exception.
What i need is a customized similar expression (one line) implementing timeout, where i need to check the state of a variable, if true then carry on else exception.
I don't wish to implement standalone timers event for that...., as there are many methods in which i need to implement this.
Hassles of Async programming!!!.
Any help please!!!
Thank You.

I believe the System.Threading.Timer class should be able to handle this in relatively little code. This version of the Timer class takes a TimerCallback delegate that it will invoke after the specified amount of time has transpired. You can also configure it via one of the constructor overloads to continue running at a certain interval, or you can have it run only a single time. Last, it takes a state object so you can pass in some data pertaining to the operation you wish to check and that object will be passed in to your delegate. Here's some example code just to illustrate how easy it is to use.
using System.Threading;
...
private Timer _operationTimeout = null;
private void CheckOperation(MyOperationData data, int timeout)
{
_operationTimeout = new Timer(new TimerCallback(CheckValue), data, timeout, Timeout.Infinite);
}
private void CheckValue(object data)
{
MyOperationData opData = (MyOperationData)data;
if (!opData.Value.Equals(opData.ExpectedValue))
throw opData.TimeoutException;
}
Hold on a second here... Don't you think you might be putting the horse ahead of the cart?

Hi Experts
Can You Explain When We Have To Use The Interface Collection.,
and what is diff. between Simple Collection And ICollection.
and Generic Collection in C#.NET
Dinesh Sharma

ICollection is an interface that extends IEnumerable [^].
Generic collection classes provides increased type-safety and in some cases can provide better performance, especially when storing value types over simple collections. Good link here on when to use generic collections.

I'm taking a brief break from my Recloser project to try a custom control. For many years I've wanted to build a scheduling app that actually works, something like Project, except that it would be usable. The stumbling block was always in developing a nice Gannt chart control with the little triangles at the edges, a rectangle to show the task duration, and a contrasting rectangle to show progress, all of which had to be draggable (yeah, I know that's not a word, but it works here). For a decade I tried with MFC to do it, but remain stumped; the GDI+ functions in the .Net Framework seem ideal for the task and I've been reading about them. I need a break from the other task, so I started this one tonight.
I've got as far as creating a container, sizing it, and populating it with the graphical elements for the display. Tomorrow I plan to start trying to Draw the elements and maybe delve into mouse interaction a bit. But I'm stuck on a proper approach. I see a lot of controls that can be resized at runtime, and the visual elements change size or positions as the mouse moves. I have a fair idea how to make the elements change one time - after a drag - by recalculating all the parameters on a Mouse_up event. But I don't have any idea how to implement a method that continuously updates the screen as the item is dragged by the mouse.
Can someone point me to a tutorial or example of implementing this behavior?

Hello, how do drawing windows form manually?
how make form Class?
Visual C#
thanks

Are you and Hakaxxxx in the same class? Or did you create a second user name thinking it would speed up getting an answer to the exact same question?
I'm not clear about what you mean by drawing a form manually. I usually use a pencil - a HB lead is best - to do this, long before I type any code.
As for making a form class, it would take far less time to type "Windows Form Class" in the Google search box than it took to write this question, and you'd find much clearer answers that way.
My guess is that you have an assignment to create a Windows Form class, and you don't have Visual Studio. That means you have to create source files in a text editor and compile them with the free C# compiler in the SDK. That's definitely the hard way, and I can't help you with it; I'm a beginner myself.
But Visual C# Express is free to download, and I recommend you do so. If you need to show the source code to your teacher, I suggest cheating. Build the project with the proper tools, then copy/paste the code into a text document.
Good luck!

All you need is to override the OnPaint method of your form and shape it as you wish inside that.
If you are looking to have your own class that will create a non-rectangular form, create a class that inherits from Form class and override the OnPaint method in that. Then use this class to create froms instead of the default one.

Hi all,
The question is as follows:
In my C# application , as i click on the image the corrosponding pixel values should be shown in two textboxes(one for row value and another for column) with the point clicked should be shown over the image. I want this to be a repititive process(i mean, any number of points could be stored). These textbox values should ultimately be stored in two diff arrays and fed into a .dll file(written in c++).
How can i achieve this?
Any help is greatly appreciated.

What do you mean by row and column value?
If you have the image in a PictureBox, handle its MouseClick event and it will give you the clicked locatio. You can set that as the textbox text and at the same time add it to a generic list of Point objects.

Row and Column are nothing but the pixel values only!
logically, i undestand that what event i have to go for but i dont have much experience on graphics programming part so thats my main problem.

When you will handle the MouseClick event, the MouseEventArgs object will have the location. The coordinates will be based on the top left of the picturebox. This means that it the location comes out to be (10,10), it means it is at a location of 10,10 with respect to the top left corner of the picture box.

Using the click event, get the mouse coordinates. Then display them in your textbox.
Add the x coordinate value in one collection, the y coordinate value in another collection.

Not sure what you mean by that.

Actually, once the point values are stored as two arrays they are transferred into a .dll(Dynamic Link Library) file which requires that collection of array as the input.
and after taking this input it generates some output.
i hope , you get me now.

Don't use an an array, use List<Point>, where Point can be found in the System.Drawing namespace. Depending upon your implementation you might also consisder BindingList<Point> and ObservableCollection<Point> instead of the list, as these both support bindin gto the UI.

Thank you for the reply!
actaully i cant go for "list" as my .dll file takes the collection as array only!

Error : "The type or namespace HRESULT could not be found(are you missing a using directive or an assembly reference)"
Code Snippet
using System;
using System.Runtime.CompilerServices;

Please help...

For C#'s COM Interop HRESULT will be returned as uint when using the PreserveSig(true) attribute. Change the method signatures in your interface of the two methods that return HRESULT to return uint instead and you should be good to go. You can also go a step further and create a uint enum that defines the possible result values:
public enum Next_HRESULTs : uint
{
S_OK 0x...,
...
}
public enum Skip_HRESULTs : uint
{
S_OK 0x...,
...
}

Hi Friends,
I want to do some registry settings changes through my .net app. Registry settings change will happen only in the "Settings" part of the app like "Starts at Windows" i.e. put an entry in the "Run" key. But to do this things in Win7 or Vista I am experiencing problems like Unauthorized access due to UAC. I am not being able to change the settings. I don't want to run the app in admin mode each time it runs, I just only want to elevate the permission at the time of changing the registry settings. Can anyone please help me out in this situation on how to accomplish this task like by modifying manifest file or putting permission attribute, anything at all.
Thanks in advance.
