Are there any calls for arranging icon by name, size, etc or 'Align to grid'?
I have never tried this, but if I had to I would first try sending LVM_ARRANGE message to the desktop window. And LVM_SORTITEMS/LVM_SORTITEMSEX might help with the sorting.
For the auto arrange you could try modify the style and using LVS_AUTOARRANGE style or the extended styles .
So you will need to use something like FindWindow to get the desktop windows and then use SetWindowLong with GWL_STYLE/GWL_EXSTYLE to modify the window style bits.

I wonder if there is any way to somehow interact with windows that are currently open on a Windows system. I am interested in getting some of their properties, namely:
Location
Dimension
is in background?
possibly window title
Preferably, I would like to do that in Java but any suggestions are welcome.
A comment by theB linked to good resources for Java. I'll run through the relevant Windows APIs, in case you want to go native with C++.
To enumerate all the top-level windows in the system, use EnumWindows. You give it a callback function with the signature of EnumWindowsProc, so it will receive each window handle as the first parameter.
You can get the window location (in screen coordinates) and dimensions with the GetWindowRect function. Pass in the window handle you received and get an LPRECT (pointer to RECT) out.
To determine whether a window is maximized, use GetWindowPlacement and check the showCmd field of the WINDOWPLACEMENT structure you receive.
Finally, to get a window's caption, use GetWindowText. (As an aside, if you want to get the text of a control in another process, you'll need to send the WM_GETTEXT message yourself.)
I have a windows application which has several sub-forms. i have to navigate through 5 or 6 forms to reach the form i need. this is time consuming since i have to open it several times through the day and i do it daily.
my need: i dont have the source project for this application, i got it as an executable program, but i need to create some application that does these steps for me automatically. In other words i need to find a way to automatically click the buttons that navigate through the forms and opens the form i need from step one.
is there any way i can do this ?
There is indeed, though generic solutions already exist to perform just this kind of function to arbitrary programs.
You can use Spy++ or a resource-editor, like ResHack or ResEdit to look at the program and get the control ids of the navigation buttons.
Once done, you can get a handle to the program itself and then send messages to it's WindowProcedure that would be generated if the user clicked the controls with a mouse,
Another alternative, is to get the position of the running target application, after you've got it's HWND, by using the GetWindowRect function. You could then use this position along with vert/horiz distances to generate mouse events.
The two have more-or-less the same result, though some applications won't work with approach #1.
In one instance, you need to use Spy++ to get the control IDs.
In the other instance, you need to use an image editor to get the pixel offsets of the controls.
In both instances, you'll need to use FindWindow, along with the window's title-text in order to get a HWND handle.
You could use a combination of the two - asking the program itself with GetDlgItem for the handle of the controls you need to click. You could then query the control for its position, before using mouse_event to position the mouse above it and again to click it.
Quite a few ways to skin this cat, actually.
Pre-existing solutions like AutoIt are said to be very easy to use and will be much easier than coding a new program for each target.
I am trying to capture windows hidden behind my application. I am using windows 7 and VC++. I have tried printwindow() function which draws the both non-client and client area of hidden window, but captured window in the device context doesn't show desktop composition effects(aero effects). Instead it shows the captured window with windows 7 basic theme.
I have also tried with GetWindowDC() to retrive the DC of hidden window, and then Bitblt() it to memory DC but the captured window doesn't show non-client area (caption, close button, minimize button etc) correctly.
Anybody faced this issue?
Please help.
Click the link below. It leads to a MSDN site that lists all the existing Windows Functions ever of all history since Windows 95 up to Windows 8 (from period where Microsoft started Windows until present). It shows old windows functions of first Windows and new windows functions added for the new windows.
http://msdn.microsoft.com/en-us/library/windows/desktop/ff468919(v=vs.85).aspx
Anyway follow this site.
You will see the name of each function as a link.
Click any of them that you are interested.
Each link there leads to another MSDN site that explains all the basics knowledge that you must know about the function before using it, that you want to learn more. What that function does, its purpose, all its parameters and how to use each one, all their flags, all parameters types, return value and at last remarks section that shed more light and sometimes gives tips about the selected function.
Of course, you don't have to read all of them. Find in the list only the necessary functions to fit your needs. The functions that will solve your problem and answer your question that you posted.
By the way, I read your post, and I think that I found in the list the necessary functions that will do what you want to do, I will list them below, and say in one sentence what each does for what you need:
AnimateWindow - Enables you to produce special effects when showing or hiding windows. There are four types of animation: roll, slide, collapse or expand, and alpha-blended fade.
FlashWindow - Flashes the specified window one time. It does not change the active state of the window.
FlashWindowEx - Flashes the specified window specified number of times. It does not change the active state of the window.
Use these functions to achieve the aero effects that you want.
SetWindowPos - Changes the size, position, and Z order of a child, pop-up, or top-level window. These windows are ordered according to their appearance on the screen. The topmost window receives the highest rank and is the first window in the Z order.
Use this function to show the hidden windows on the top side (above all other windows) and on the screen front of you. The operating system will automatically draw the both non-client and client area of these windows without using any gdi, draw and paint functions yourself.
If you want these windows to return back to their previous state (where they were hidden), then save their state with GetWindowPlacement function and later call SetWindowPlacement to bring them back to their hidden state. You can try GetWindowRect and SetWindowPos instead to achieve the same goal.
I also think that you will be interested in GetWindowTheme and SetWindowTheme functions and all the draw theme functions (BackgroundEx, Edge, Icon, Text, TextEx).
There are more theme functions. Find in msdn and in other sites on the web.
I am trying to show a web page in a dialog control. All is working fine till I maximize the parent window, the inner control with webpage retains its size and so a blank area is left at the side of window. I want to know is there any WS_* message or something I can use to auto resize control when we resize the main window. I am using resource hacker so may be there can be some trick I should know.
Any help is appreciated.
Thanks.
The application must perform the resize. And it does so when it receives a WM_SIZE message for the parent control.
You are not going to be able change this by modifying the resources in a pre-existing binary. You are going to need to write some code to respond to that message.
The way I'd try seeing as I've never tried to hack something like this in.
Would be to see if the web control had an anchors property.
Its should be being passed a wm-size message, it's just not doing anything with it.
If you anchor all four corners of the webcontrol it should resize relative to it's parent.
The other way this is done is through explicit code that handles a resize event, don't think you could hack that in very easily though.
To modify a window of another program, I need to find a specific SysTreeView32 in it using EnumChildWindows API call.
When I inspect the window using Spy++, there are a number of SysTreeView32's in it but all are greyed out except one, which is the one I'm looking for.
The following picture is an example of grey items:
Why are the shown items gray and what API call does Spy++ use to know whether it should grey out an item or not?
Those are just non-visible windows - ie HWNDs that don't have the WS_VISIBLE style bit set. They are often worker windows - windows that just exist to process various messages in the background - or in some cases are UI that's yet to become visible. For example, a window that lets you hide or show a toolbar may just hide it by making it invisible rather than destroying it and recreating it later.
In your specific case, the WorkerW could be a placeholder for some other piece of UI that's not needed right now, while the msctl_statusbar32 looks like it's a hidden status bar.
