  • Removing and restoring Window borders

    - by Laurence
    I want to remove the window borders of another process in C#; I used RemoveMenu to remove the borders. It almost works but I have 2 problems left: I need to remove the borders twice, the first time the menu bar still exists. I can’t restore the menu’s This is what I already wrote: public void RemoveBorders(IntPtr WindowHandle, bool Remove) { IntPtr MenuHandle = GetMenu(WindowHandle); if (Remove) { int count = GetMenuItemCount(MenuHandle); for (int i = 0; i < count; i++) RemoveMenu(MenuHandle, 0, (0x40 | 0x10)); } else { SetMenu(WindowHandle,MenuHandle); } int WindowStyle = GetWindowLong(WindowHandle, -16); //Redraw DrawMenuBar(WindowHandle); SetWindowLong(WindowHandle, -16, (WindowStyle & ~0x00080000)); SetWindowLong(WindowHandle, -16, (WindowStyle & ~0x00800000 | 0x00400000)); } Can someone show me what I did wrong? I already tried to save the MenuHandle and restore it later, but that doesn't work.

  • How can I create a menu in the start menu for my program?

    - by Joe
    This may be an easy question but I am not even sure of the terminology to search, so I have to ask. I want my program to have a menu when it is hovered over if it is pinned to the start menu. I am attaching a screenshot where windows powershell illustrates this function, and presents a list of tasks. Other programs sometimes use this to list recently opened files, etc. I am sure this is standard enough that there is a tutorial on it somewhere, would someone mind pointing me to it, or explaining how to do this? I hope that it doesn't matter too much what language is used, but I am proficient in Delphi, C++, and C#.

  • GetWindowLongPtr fails if called when handling WM_CREATE

    - by Semen Semenych
    Calling the GetWindowLongPtr function for a dialog box with the DWL_USER parameter fails when done from the WM_CREATE handler. It gives no error (checked that, the return value is always zero), which, according to the MSDN documentation, occurs only if SetWindowLongPtr has not been called previously. However, I call it after registering the window class, and properly call the SetWindowPos after that. Finally, calling GetWindowLongPtr in any other event handler, that is, later than WM_CREATE, works fine. Is there something I'm missing in the initialization sequence, or maybe the messages are sent in some not so obvious order?

  • DeferWindowPos and SWP_SHOWWINDOW/SWP_HIDEWINDOW

    - by Tom Bell
    I am writing a virtual desktop application which utilises the DeferWindowPos API functions. The current method I am using is moving the windows off the screen if they're not on the current virtual desktop. However I know wish to also hide the windows that are off-screen so they do not appear on the task bar. I have attempted this by also passing SWP_SHOWWINDOW/SWP_HIDEWINDOW to the DeferWindowPos() calls. I have read a few sites regarding this and one of them suggested that if SWP_SHOWWINDOW/SWP_HIDEWINDOW are passed, then the window will only show or hide, and no reposition. Can anyone confirm this, or am I doing something wrong?

  • Creating a Transparent Bitmap with GDI?

    - by user146780
    I want to implement a layering system in my application and was thinking of creating a bunch of transparent bitmaps, adding content to them then blitting them on top of each other, how can this be done without setting each pixel to (0,0,0,0). I'm using Pure win32, not MFC, thanks.

  • C/C++ detect network type

    - by Gavimoss
    I need to write a win32 c/c++ application which will be able to determine whether the PC it's running on is connected to one of 2 networks. The first network is the company LAN (which has no internet connection) and the second network is a standalone switch with a single PC connected to it (the PC that the program is running on). I'm pretty new to network programming but so far I have tried testing to see if a network drive which is held on our LAN can be mapped. This works fine if the PC is connected to the LAN, the drive mapping succeeds so so LAN detection is successful. However, if the PC is connected to the switch, this results in a VERY long timeout which is not a suitable as it will delay the program so much as to make it unusable. Does anyone have any alternative suggestions? I'm using c/c++ in VS 6.0

  • How does Process Explorer enumerate all process names from an XP Guest account?

    - by Joe
    I'm attempting to enumerate all running process EXE names, and have stumbled when attempting this on the XP Guest account. I am able to enumerate all Process IDs using EnumProcesses, but when I attempt OpenProcess with PROCESS_QUERY_INFORMATION Or PROCESS_VM_READ, the function fails. I fired up Process Explorer under the XP Guest account, and it was able to enumerate all process names (though as expected, most other information from processes outside the Guest user-space was not present). So, my question is, how can I duplicate the Process Explorer magic to get the process names of services and other processes running outside the Guest account user-space?

  • How can I pass Arguments to a C++ program started by the Registry?

    - by Y_Y
    Hello, I'm creating a Win32 program that will be executed every time the computer turns on. I manage to do this by adding the .exe path into the registry. The problem is; I want to make the program appear minimized in the system tray when the computer is turned on but if I double click it [after the computer turns on and the program is not currently running] the program should appear on its normal [maximized] size. Question, I was thinking on whether is was possible to pass an argument to the program when the program is executed from the registry. Is this possible? If yes/no, how would I manage to do this? (Using windows XP) Thanks.

  • How to get information about a Windows executable (.exe) using C++

    - by ereOn
    Hi, I have to create a software that will scan several directories and extracts information about the executables found. I need to do two things: Determine if a given file is an executable (.exe, .dll, and so on) - Checking the extension is probably not good enough. Get the information about this executable (the company name, the product name, and so on). I never did this before and thus am not aware if there is a Windows API (or lightweight C/C++ library) to do that or if it is even possible. I guess it is, because explorer.exe does it. Do you guys know anything that could point me in the right direction ? Thank you very much for your help.

  • Detecting the Loopback Adapter

    - by BlueSkies
    What is the best way for detecting whether a network interface is a loopback adapter? The windows API's GetAdaptersInfo and GetAdaptersAddresses state in the documentation that they will return whether an interface is a loopback through the Type (MIB_IF_TYPE_LOOPBACK) but neither of these do for the Microsoft Loopback Adapter at least, it is reported as a standard ethernet interface. I could try checking for the default MAC of the Loopback adapter but this can be easily spoofed. I could check for the name "Microsoft Loopback Adapter" in the description but this may have translation issues and may lead to other issues. IP addresses can also be changed. What is the most robust method for doing this?

  • How do I tell if the master volume is muted?

    - by John_Sheares
    I am using the following to mute/unmute the master audio on my computer. Now, I am looking for a way to determine the mute state. Is there a just as easy way to do this in C#? private const int APPCOMMAND_VOLUME_MUTE = 0x80000; private const int WM_APPCOMMAND = 0x319; [DllImport("user32.dll")] public static extern IntPtr SendMessageW(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam);

    In win32 programming in C: Whats the best way to execute a win32 console program within another win32 program, and have the program that started the execution capture the output? At the moment I made the program redirect output to a file, but I am sure I must be able to open some sort of pipe?

  • How is executed a SendMessage from a different thread?

    - by Lorenzo
    When we send a message, "if the specified window was created by the calling thread, the window procedure is called immediately as a subroutine". But "if the specified window was created by a different thread, the system switches to that thread and calls the appropriate window procedure. Messages sent between threads are processed only when the receiving thread executes message retrieval code." (taken from MSDN documentation for SendMessage). Now, I don't understand how (or, more appropriately, when) the target windows procedure is called. Of course the target thread will not be preempted (the program counter is not changed). I presume that the call will happen during some wait function (like GetMessage or PeekMessage), it is true? That process is documented in detail somewhere?

  • C++, WCHAR[] to std::cout and comparision

    - by michal
    Hi, I need to put WCHAR[] to std::cout ... It is a part of PWLAN_CONNECTION_NOTIFICATION_DATA passed from Native Wifi API callback. I tried simply std::cout << var; but it prints out the numeric address of first char. the comparision (var == L"some text") doesn't work either. The debugger returns the expected value, however the comparision returns 0. How can I convert this array to a standard string(std::string)? Thanks in advance

  • C++ - Creating folder method

    - by Matthew
    I have the following method in C++: void create_folder(LPCWSTR full_folder) //Method to create folder in case it does not exist { if(!CreateDirectory(full_folder,attr)) //Checking whether the folder already exists { switch (GetLastError()) { case ERROR_ALREADY_EXISTS: printf("The folder already exists!\n\n"); break; case NULL: printf("The folder does not exist!\n\n"); printf("The folder was created successfully!\n\n"); break; } } } In case the folder already exists, the correct message is displayed on the screen. However, if the folder does NOT exist, nothing is displayed on the screen, that is, the part identified by case NULL is not executed. How can I solve this problem? In other words, how can I get the code after the case NULL to run if the folder does not exist?

  • Unicode string handling using Windows API

    - by DeadMG
    I always assumed that Unicode string handling was some dark art. However, I've seen that the Windows API has functions for comparing Unicode strings, for example. Does that mean that it's actually feasible to write a Unicode string class that can perform simple actions like sorting, equality comparison, and extraction from a file? Or are there hidden gotchas in the use of these functions that makes it actually a really bad idea? I'm just looking at libraries like ICU and they seem incredibly over-complicated compared to what a Unicode string class backed by the Windows API could actually look like, which would resemble the Standard string classes quite closely.

  • CopyFileEx and 8.3 file names

    - by Lobuno
    Suppose you have 2 files in the same directory: New File Name.txt and NewFil~1.txt If you use CopyFileEx to copy both files to the same destination, maintaining the same names, you will end up having only ONE file (the second one replaces the first one) which can be sometimes not a good thing. Any workaround for this behavior?

  • What does explorer use to open a file?

    - by dauphic
    I'm attempting to hook into whatever explorer calls when a file is opened (double-click, context menu open, etc.), however I can't figure out which function that is. Originally, I thought it was ShellExecute, as that does the same thing as far as I can tell, but after hooking into it I learned that it's only used when a new explorer window is opened. Any ideas which function I should be hooking?
