  • deliver c++ application for the final customer

    - by Nebrass
    I am working on a c++ windows application on visual studio 2010. I want to deliver my application to my customer so he can use it easly, without the obligation of installing visual runtime fx. And to be executed every where. How do I set up the installer so that the customer does not need to separately install any required Visual Studio runtime libraries? Please i want a solution for this problem, because my costumers are so far from computing, they love just "next, next, install, finish" system. Thank you for your help.

  • C++ Multi Monitor - Find All Visible/Open Windows

    - by Paul
    I'm trying to find all the windows of ANY kind that are open (and have a taskbar 'button'). I have no problems finding the list processes/hWnd's, and then cycling through those, but how do I determine if a process/hwnd has a window open? (even if minimized). I've tried doing different combinations of the window parameters (such as WS_POPUP etc) but none of the parameters (or combinations of parameters) that I could find would give me all the open windows without some sort of false positives. As an example of a false positive was the fact that it gives me two 'windows' for google talk (even though one was open). Another false positive is considering the start menu as an open window. Any ideas? Solutions? I've been working on this for a while and its been driving me a bit insane. Note: I'm doing this for windows 7 (at this point). I'm not sure if there's any difference between how you would do this between XP and 7, but I thought it might be relevant.

  • Using FILE_FLAG_NO_BUFFERING will return noticeable speed gain?

    - by 9dan
    Recently noticed detail description of FILE_FLAG_NO_BUFFERING flag in MSDN, and read several Google search results about unbuffered I/O in Windows. http://msdn.microsoft.com/en-us/library/aa363858(v=vs.85).aspx I wondering now, is it really important to consider unbuffered option in file I/O programming? Because many programs use plain old C stream I/O or C++ iostream, I didn't gave any attention to FILE_FLAG_NO_BUFFERING flag before. Let's say we are developing photo explorer program like Picasa. If we implement unbuffered I/O, could thumbnail display speed show noticeable difference in ordinary users?

  • TPageControl tab area OnMouseEnter OnMouseLeave events

    - by daemon_x
    Hello, I need to catch the "OnMouseEnter" and "0nMouseLeave" for a certain area of the TPageControl component. With that specific area I mean the whole "tab header" rectangle. The problem is, that the page control doesn't catch the messages (I'm catching internal control messages CM_MOUSEENTER and CM_MOUSELEAVE) in the "empty" space. The aim for me is to draw a small arrow in the right empty side when user hovers in the red framed area (and drawing is just piece of cake) and erase it when leaves this area. And I'm don't care about the overflow of the tabs (which causes to draw scrolling double button) - that will never happen.

  • (Win Api) Check if an external application window is on the taskbar

    - by Jorge Branco
    Hello. I'd like to know if it's possible to know if an external application has an window that is showing up on the taskbar. I have a program that sometimes shows up an error message and it appears on the taskbar. If I "close" the message, it will go invisible, but from what I've seen it still exists. So the only way for me to know if that window is visible and thus "clickable" is to check if it is being shown on the taskbar or not. How can I do this? Thanks

  • Prevent monitor from powering on

    - by concretemixer
    I'm turning off the monitor using SendMessage(HWND_BROUADCART, WM_SYSCOMMAND, SC_MONITORRPOWER, 2). That works, but the monitor turns back on when someone touches the keyboard or mouse. I tried to get rid of this using the DevicePowerSetDeviceState function with DEVICEPOWER_CLEAR_WAKEENABLED for the keyboard and mouse: it returns no error, but has no effect either. How can I prevent the monitor from powering back on in Vista and Windows7?

  • Windows service: Listening on socket while running as LocalSystem

    - by Socob
    I'm writing a small server-like program in C for Windows (using MinGW/GCC, testing on Windows 7) which is eventually supposed to run as a service with the LocalSystem account. I am creating a socket, and using Windows Sockets bind(), listen() and accept() to listen for incoming connections. If I run the application from the command line (i.e. not as a service, but as a normal user), I have no problems connecting to it from external IPs. However, if I run the program as a service with the LocalSystem account, I can only connect to the service from my own PC, either with 127.0.0.1 or my local address, 192.168.1.80 (I'm behind a router in a small local network). Neither external IPs nor other PCs in the same local network, using my local address, can connect now, even though there were no problems without running as a service. Now, I've heard that networking is handled differently or even not accessible (?) when running as LocalSystem or LocalService or that services cannot access both the desktop and the network (note: my service is not interactive) at the same time due to security considerations. Essentially, I need to find out what's going wrong/how to listen for connections in a service. Is running as NetworkService the same as running as LocalSystem, but with network access? Surely there must be servers that can run as background services, so how do they do it?

  • How To Prevent Processes From Starting?

    - by Rob P.
    I'm toying around with a very simplistic sort of process-monitor. Currently, it gets a list of the running processes and attempts to kill any process that is not white-listed. What I'm looking for is a way to prevent a process from starting that isn't on the white-list. If that's possible. My knowledge level in this area is pretty non-existent and my Google-fu only returns websites discussing Process.Start() :( Can anyone point me in the right direction?

  • capture the last WM_SIZE

    - by Michael
    When I resize my window I want to tell another part of my program that my window has changed size. I read on MSDN that: WM SIZE Message The WM SIZE message is sent to a window after its size has changed. However, I receive the WM_SIZE even when dragging. I noticed that there is also a WM_SIZING message that is sent when my window is resizing. At the moment I do not see the difference between WM_SIZE and WM_SIZING. Is there some way I can capture the very last WM_SIZE message, as to not "spam" my program with resize messages?

  • Rendering sub tools on vertical toolbar

    - by user146780
    I was wondering how ex Photoshop and Expression Design render sub tools. These show up when for example you hold your mouse down on the fill tool, a sub menu comes up to your right with the fill and gradient tools. I'm just not sure how to go about this because this sub menu would essentially have to be an extension of my toolbar, but then it would find itself on my Frame control. How is this handled? Would it be a good idea to just paint on my frame?

  • How do I determine the coordinates of controls in a WM_INITDIALOG message?

    - by René Nyffenegger
    I am having troubles to determine the (what I believe to be the) client coordinates of a (radio button) control in the WM_INITDIALOG message of a DlgProc. Here's what I try: // Retrieve coordinates of Control with respect to the screen. RECT rectOrthoButton; GetWindowRect(GetDlgItem(hWnd, IDC_ORTHO), &rectOrthoButton); // Translate coordinates to more useful coordinates: those that // are used on the dialog. // In order to do the translation we have to find the top left // point (coordinates) of the dialog's client: POINT dlgTopLeft; ClientToScreen(hWnd, &dlgTopLeft); // With these coordinates we can do the translation. // We're only interested in top and left, so we skip // bottom and right: rectOrthoButton.top -= dlgTopLeft.y; rectOrthoButton.left -= dlgTopLeft.x; use_top_and_left(rectOrthoButton.top, rectOrthoButton.left); I expected rectOrthoButton.top and .left to be the top left coordinates of my control with respect to the dialog's client area. It turns out they aren't and I am not sure what they point to as rectOrthoButton.left is equal to -40.

  • What is the meaning of client coordinates in SetWindowPos

    - by user1775315
    The documentation for SetWindowPos says the following for the X and Y parameters: X [in] Type: int The new position of the left side of the window, in client coordinates. Y [in] Type: int The new position of the top of the window, in client coordinates. By "client coordinates", does it mean that the parameters specify the position of the client area of the window, or that they specify the position of the window (not the client area) relative to the parent window's client area? Or something else?

  • Can single-buffer blocking WSASend deliver partial data?

    - by CodeAngry
    I've pretty much always used send() with sockets and now I'm moving onto the WSA functions. With send(), I have a sendall() helper that ensured all data is delivered even if it didn't happen in one try and a partial send occurred on first call. So, instead of learning the hard way or over-complicating code when I don't have to, decided to ask you: Can a blocking WSASend() send partial data or does it send everything before it returns or fails? Or should I check the bytes sent vs. expected to send and keep at it until everything is delivered? ANSWER: Overlapped WSASend() does not send partial data but if it does, it means the connection has terminated. I've never encountered the case yet.

  • Scrollbar moves back after WM_VSCROLL

    - by user146780
    I have a window with its own H and V scrolling. I'm handling the event like this: case WM_VSCROLL: SetScrollPos(hWnd, SB_VERT, (int)HIWORD(wParam), TRUE); break; all I want is for the position of the scroll bar to stay once I release my mouse but what it's doing is just going back to the top after. What am I doing wrong? Thanks

  • NetUserAdd() to Remote Desktop Group?

    - by Brett Powell
    Is there anyway to give a newly created user from NetUserAdd() remote desktop access and/or administrative rights? I know it is possible, at least for Remote Desktop, and I have been reading through the MSDN but nothing seems to hint at what is required to be set for it to work.
