Ok, I'm trying to create a new interface for an existing program. Basically I want to get information (pictures, text) and port it into a new window in a different format. I've come to realize that screen scraping is probably my best bet.
My problems are:
How do I go about screen scraping?
All I can find involves scraping from webpages, this is a windows application.
Is there some way to get a "Window ID" to identify which screen I'm scraping from?
Does the screen I'm using need to be on top? because I am creating a new interface because I want to use it.
Is there a better way to go about this?
Any advice on where to begin?
thanks,
jack

This is a perticularly troublesome issue since you are dealing with a windows application you want to scrape the data from. You can get the window handle! It is kind of involved but you can get it from it's location, or, you can get it from the module handle but you'll need to use windows API which involves some interop. In the end, you might not even be able to get the information depending on if standard windows controls are used or not. Assuming you have the window handle and that the data you are getting is in a standard list box, you can get at it. You mentioned picures though and I know of no non-convoluted way to scrape that. You can get a binary image right off the screen but the window will need to be made topmost, but what if another window overlaps between the time you bring it to the top and you start scraping? Screen scraping is generally reserved for application where data is in text that is rendered to a destination that supports reading it back as text. In the GUI world you'll need to rely on asking some control for that information and that may or may not be possible, depending on the control which rendered it.
If possible, I'd look at getting at the data in some other way, perhaps its storage medium?
Probably not much help but...

How do you add HTML (and their corresponding image files) to a solution and code a browser control to open them? I've added a new folder to the solution and placed the html and image files into it, however, I don't know if this is the correct way to add these files to a solution or how to open the html in the browser once they are added. Any help would be much appreciated.
C.S.

I have to implement two controls - MyPicture (extends PictureBox) and MyLabel (extends Label). They both have the same additional properties and fields, and the properties do the exact same thing in both these classes. Each property calls Invalidate methods. Both classes have a constructor which puts some default values to the fields, and override the OnPaint method.
Now the problem is: how would you implement this hierarchy in C#? I'm quite new to C# and OOP and I am not fully accustomed to it. I know I can inherit from one class and implement many interfaces. But the additional properties cannot be an interface becouse it contains fields and I would have to write exactly the same code in both classes.
So my request is - how would yopu implement this hierarchy?

In C++, this might be a candidate for multiple inheritence. With C#, interfaces are a poor substitute, because as you say, you end up writing the same code in both classes.
However, you still may want to use an interface so that some other class can utilize your specialized class' methods and properties. So, to avoid duplicating the same code, you write a class that implements the functionality, and the classes that implement the interface instantiate the helper class and call its methods.
Does that help?

Well, I think I can't instantiate one of the classes and call its methods. So I have to double the code?
So I have another question - it happens to be a DLL, so is it possible to write the dll in Managed C++, using multiple inheritance, and then use it in C#?

I have a process that starts and runs MS Word for about 10 seconds. Sometimes Word seems to hang; it stays open for 'ever'. Is there an way that I can run a process2 independently of process that checks to see if Word is running and if it is, if it has been open for about a minute, and if it has, to stop it? Thanks in advance.

You can do the following. Run the follong code to see if MS Word is running and if it is it will kill the process.
using System.Diagnostics;
private Process[] WordProcessList;
.....
int index;
WordProcessList = Process.GetProcessesByName("WINWORD");
for( index = 0; index < WordProcessList.Length; index++)
{
WordProcessList[index].Kill();
}

How to develop a dropdown list like control from scratch.
|
|
|
|
|
Just atextbox and a flat button in the right and some other textbox without border to actlike the list.
|
|
|
|
|
yes, but when i tried to do that, the text box is not overlaping on to other controls on the form. and when i use the control inside a panel/group box the part of the textbox which is out of the panel is not visible?
is there anyway to avoid that??
|
|
|
|
|
Just try BringToFront(); method of this textbox
|
|
|
|
|
it doesn't help since the parent of the textbox used as a list is the control not the form! when BringToFront() is used it brings the textbox to the front of the control but not the form on which the contol is? currently i have a work around which changes the parent of the textbox and positions it so that it aligns with the rest of the control. it works.
the problem is i don't want to change the parent of the textbox just to draw it on top of the z-order

I downloaded a project in C# and would like to compile it. There is no project or solution file available, so, I created a new project and put everything there.
PROBLEM:
There are many files stored in different sub-directories (of the project directory). The files in each directory belong to the same namespace.
For example :
In Main.cs of the project directory contains:
using ABC.namespace1
using ABC.namespace2
and in the directory {project dir}/ABC/namespace1, there is a bunch of class files declaring as: namespace ABC.namespace1
MY QUESTION:
Do I need to copy all the files of the sub-directories to the project directory to compile it or there is a setting in Visual Studio that allows this. Right now, when I tried to compile it, I got the message:
"The type or namespace name 'namespace1' does not exist in the class or namespace ABC. Are you missing assembly references ?"
Thanks a lot for any help

It may be a .dll with it and then you may have a reference first to it.

i want to write to program for uploading file to webserver, but i don't know the mechanism of uploading file
Show me detail if you can
Thank you

You could use something simple like the following:
WebClient <code>Client</code> = new WebClient();
Client.UploadFile("http://www.MyWebsite.com/index.aspx", "C:\MyFile.aspx");
Note: You should also consider providing checkups for your upload mechanism (such as checking if the file does exist, or that its contentLength is greater zero).
Hope this helps

Polis
Can you practice what you teach?

Hi,
Should I use TableLayoutPanel for my Form with FixedDialog style?
I can't understand when i need in TableLayoutPanel.
Best regards.

You should use TableLayoutPanel when you want your controls laid out in rows and columns.

Hi,
I want to ask how to execute a static function in a user created application domain. I am trying to run following sample code. But it seems that the method that I am trying to execute in my created domain always executed in the default created domain (caller domain).
public void ExitProcessTest()
{
string applicationTitle = "ApplicationToBeKilled";
Assembly asm1 = Assembly.GetAssembly(typeof(OSP.Forms.ErrorBox));
AppDomainSetup ads = new AppDomainSetup();
ads.ApplicationBase = @"file:///C:\Components.NET\Testing\TestProject\bin\Debug\";
ads.PrivateBinPath = AppDomain.CurrentDomain.BaseDirectory;
ads.ApplicationName = applicationTitle;
AppDomain newappDomain = AppDomain.CreateDomain(applicationTitle, null, ads);
Assembly asm = newappDomain.Load(asm1.FullName);
Type type = asm.GetType("OSP.Forms.ErrorBox");
type.InvokeMember("ExitProcess", BindingFlags.Public | BindingFlags.Static | BindingFlags.InvokeMethod, null, null, new object[] { applicationTitle });
Thread.Sleep(15000);
}
public static void ExitProcess(string applicationTitle)
{
//It's better to close the application, otherwise, could throw many other errors
try
{
ApplicationTitle = applicationTitle;
Thread exitThread = new Thread(new ThreadStart(ApplicationExitThread));
exitThread.Name = "ExitThread";
exitThread.Start();
}
catch (Exception exc) { ShowError(exc, "Osp.Shared", null, "script_error@etb.bel.alcatel.be"); }
}
private static string ApplicationTitle;
private static void ApplicationExitThread()
{
try
{
Form f = new Form();
f.TopMost = true;
f.Size = new Size(370, 60);
f.BackColor = Color.Red;
f.FormBorderStyle = FormBorderStyle.None;
Label lbl = new Label();
lbl.BorderStyle = BorderStyle.FixedSingle;
lbl.ForeColor = Color.White;
lbl.Font = new Font("Verdana", 10, FontStyle.Bold);
lbl.TextAlign = ContentAlignment.MiddleCenter;
lbl.Dock = DockStyle.Fill;
lbl.Text = "The " + ApplicationTitle + " will exit in few seconds.\nSorry for the inconvenience.";
f.Controls.Add(lbl);
f.StartPosition = FormStartPosition.CenterScreen;
f.Show();
f.TopMost = true;
f.Invalidate();
f.Update();
Thread.Sleep(1000);
for (int i = 5; i > 0; i--)
{
lbl.Text = "The " + ApplicationTitle + " will exit in " + i + " second" + (i > 1 ? "s" : "") + ".\nSorry for the inconvenient.";
lbl.Update();
Thread.Sleep(1000);//to ensure the error mail is sent!
}
//Process.GetCurrentProcess().Kill();
MessageBox.Show(AppDomain.CurrentDomain.FriendlyName);
}
catch (Exception exc) { ShowError(exc, "Osp.Shared", null, "script_error@etb.bel.alcatel.be"); }
}
