Excellent. Good luck.

Just a quick question can Exchange Web Services be used in windows applications as well as web apps?
Also, do you have an example of how to use the CopyItem method?
Thank you,
Mel

Dear programmers have a question, I have the contents of the database are displayed on the listview. Suppose we have a row numbers 1,2,3,4,5. after the removal of such line number 2, line numbers will be 1,3,4,5. How to do that after deleting a row will automatically renumber as 1,2,3,4. Thanks in advance

If they are coming from a database directly into the listview, there is a very good chance that the nunbers are the record ID in the database, and an even better chance that they are autonumber - i.e. the database assigns them, incrementing as it goes, and you do not have to worry about duplicates, because the database will not allow that.
If so, then do not attempt to change them: in the real world changing a record ID is not a good thing to do, and it can cause enormous problems, even if the database would let you - which for autonumber fields it won't.
Hide the column instead, if it offends you!

I think this is a very correct answer to this question. The same question was posted in the Questions & Answers sections too..

Hi,
I am trying to do an app which has children windows inside it, and make it capable of when drag the mouse off the parent window it undocks and float all around the desktop, but for some reason i can seem to accomplish this. I am using the SetWindowLong method to change style of the window from WS_CHILD to WS_POPUP but it doesn't work, can someone please show me some code to make it work 
long lastStyle = NativeMethods.GetWindowLong(myControl.Handle,
(int)NativeMethods.GetWindowLongConst.GWL_EXSTYLE);
long newStyle = NativeMethods.SetWindowLong(myControl.Handle,
(int)NativeMethods.GetWindowLongConst.GWL_STYLE,
(uint)NativeMethods.WindowStyles.WS_POPUP);
newStyle = NativeMethods.SetWindowLong(myControl.Handle,
(int)NativeMethods.GetWindowLongConst.GWL_EXSTYLE,
(long)(NativeMethods.WindowStylesEx.WS_EX_APPWINDOW | NativeMethods.WindowStylesEx.WS_EX_TOOLWINDOW));
myControl.Location = new Point(100, 200);

I would like to search through the buttons of a window handle and search for a specific button and if it exists perform an action, is there a way to do this?
If not, how can I identify a button and simulate a click based on the following info?

If its a real native Win32 button, you can use FindWindow or FindWindowEx to find the window and send a BM_CLICK or WM_COMMAND message with SendMessage. If its not a native button (i.e. a WPF app, etc.), you can't do that and your only option is to simulate a mouse click with the mouse_event API.

Hi,
Thank you for the reply, do you have any code examples for this, I'm having a hard time finding anything online that looks like it will work with what I am doing. Or that will work with the window information I posted in my initial post. I do not believe it is a real native Win32 button.

Well, I don't have the HP openview software, so I couldn't tell you for sure. I don't know what tool your initial output is from, so try use Spy++ (comes with Visual Studio) instead. Use the binocular tool (6th button) then drag the cross hair thingy onto the title bar of the window and hit ok. NOTE: you need to start the HP app first, the refresh in the new Spy++ doesn't always work. Anyways... after you hit ok, you'll go to the window tree. You can expand the tree and see what controls are there. If the button is listed, its a native control. You might need to drill down in the tree to find it. Or you can just drag the cross hair directly onto the button.
If its not a native button, or even something like a toolbar its trickier... but it seems like from your output you can find the button of interest and get its screen rectangle. So then just use mouse_event() http://msdn.microsoft.com/en-us/library/ms646260(v=vs.85).aspx to simulate left button down | left button up at the absolute screen coordinates.

Hi,
Thanks again for the reply.
The cross hairs option gave me this, it looks like the button stays in the same general area no matter the window size, but its Class Name is not usable (all buttons are named that) and it does not seem to have any other uniquely identifiable information about it?
Is my best option the coordinates based mouse click?

Ok, so its a custom control with a class name of "SWT_Window0", so you can't search by class name. As you said, all the buttons have the same class name. It also doesn't seem to store the button text in the standard location, so you can't use that either. Hard coding the window coordinates is not a good idea because if they redesign the screen, your app will break.
It looks like your best bet is to get the button by ID (5841730), to do that, you kind of need to navigate down the tree yourself... what I mean is lets say the window structure is like this:
TopLevelWindow
|- Button you want
so you'd find the TopLevelWindow with FindWindow() (using the classname or window text) and get the HWND and then you'd use that in a call to GetDlgItem() using the 5841730 to get the button.
if the window structure is something like:
TopLevelWindow
|- Some other window
|- Button you want
you'd have to get the "some other window" somehow to use GetDlgItem() or you'd have to recurse through all the windows.
Once you get button HWND, you'd call GetWindowRect() on it to get the screen coordinates and then use the mouse_event with the absolute flag to do the left down and left up. Multi-monitors are handled by the APIs already.

Hey,
Thanks for taking so much time to help, I just closed and reopened the application and the ID actually changed, this time it was 3738914.
Is there a way to search through, maybe I could use that to identify it?
Thanks for the help.

If there is nothing unique about the window, then there is not much you can do. You need a bullet proof way to ID the window. What if they happened to move a "format hard drive" button there? 
|
|
|
|
|
Haha, that'd be real bad
I was hoping I could recursively search through the buttons somehow?
Maybe I could use reflector on the exe and decompile it? I'm not real familiar with reflector but maybe I could figure it out?
I've always had the mindset that anything that can be done by a person, can be imitated with code?

Actually I'm not sure if the mouse click will work because we have 2 monitors here and the coordinates of the button will change if it is on the other monitor.

If you are planning on doing a considerable amount of interacting with *other* applications I would suggest looking into this:
http://www.autoitscript.com/site/[^]
I wrote and posted a .NET wrapper on their forums.
You can do all sorts of cool stuff like find and interact with any class (buttons, listviews, etc..)
Only native Win32 classes of course tho.

Hi Jason,
I actually learned to code on AutoIT, so I am very fond of it
Do you post under the same user name over there so I can search for your .net wrapper?
If you look at my original button identification code in this post, you'll notice I used AuInfo.exe to capture that information, I think AIT at least identifies a classNN name for it
Thanks!

In a small desktop app, I'd like to allow users to open a specific web search in their default browser. Easily done with FF, IE and Opera using Process.Start. But I have yet to find a command line switch for Chrome. No answers from any of the Chrome forums I've tried. I've looked at numerous lists of Chrome command line arguments and see nothing regarding a search argument. Seems amazing that Chrome would lack the functionality. Anyone have a suggestion?

Process.Start("http://www.google.com/search?q=your+keywords+here");
uses whatever is your default browser.

This works of course, but I'd like to have the app open the user's default browser and their default search engine. And, if future changes at Google result in the search string being altered, then the process could fail.
I can launch IE or FF and search like this:
Process.Start("IExplore.exe", "? lizard")
Process.Start("firefox.exe", "-search lizard")
But Chrome apparently doesn't have a similar command line arg. At least I haven't been able to find it.

I suggest you try:
Process.Start("chrome.exe", "lizard")
and see if you like the outcome.
[ADDED] and you could add some automation that clicks a button for you... [/ADDED]

tried this and it doesn't work for me. Some reason it populates the URL with "lizard/" and complains it cannot find "lizard"
