I've used UPX before to reduce the size of my Windows executables, but I must admit that I am naive to any negative side effects this could have. What's the downside to all of this packing/unpacking? Are there scenarios in which anyone would recommend NOT UPX-ing an executable (e.g. when writing a DLL, Windows Service, or when targeting...
Hi, I am trying to passing in 3 pointers to a DLL function. I have: { $code=1; $len=100; $str=" " x $len; $function = new Win32::API(DLLNAME,'dllfunction','PPP','V'); $function->Call($code,$str,$len); } The DLL is defined as void dllfunction(int* a, char* str, int* len); The DLL will modify all the variables pointed by the three ...
Windows has GetFileTime API which allows getting file time information by open file handle. What I wanted to know is, if it is possible to get this information by file name without opening the file explicitly. And if possible is it also applicable to Windows Mobile platform? ...
Hi, I want to store some information in the EPROCESS structure of the process in windows NT kernel. My aim is that when winlogon is called I want to assign a unique value to the next process based on which user logs in. But I do not know where to store this unique ID. I have tried and succeeded in modifying some information (like the t...
Is there a way to view the register contents in each stack frame in a crash dump? The registers window seems to contain the registers when the exception occurred but it would be useful to be able to see their contents in each stack frame. ...
I'm using a 3rd party DLL written in unmanaged C++ that controls some hardware we have. Unfortunately this DLL crashes now and then and I've been tasked to make it "reload" automagically. I'm not too sure about how to proceed to get best results. My project uses C++.Net 2.0 (2005). I'm wrapping the 3rd party stuff in a separate DLL. I'...

I've hit upon a problem with WSADuplicateSocket, which I'm using to duplicate a socket for use by a different process. It works find when both processes are running under the same Windows user, but fails with error code 10022 (WSAEINVAL) when they are running under different users. Specifically, the process calling WSADuplicateSocket is...

I want to make a WPF Window that behaves like a context menu. So, for instance - when I show the wpf window, I want it to be the topmost window and from there on out, if the user clicks anything outside of that window I want the window to be hidden again. So far I have tried quite a few techniques but the only one that I found that kin...
I do have to say I'm fairly inexperienced when it comes to C++, don't be too harsh on me. Recently stumbled unto the wonders of the win32 API and have chosen to practice using it (I'd rather not use MFC/wxWidgets/etc at this point, just for educational purposes). Well, my real question is: How do you properly code your win32 GUI stuff ...
Our app allows multiple files to be selected in a file selection dialog which is shown via the GetOpenFileName function (this question also applies to folks using CFileDialog, etc...) There appears to be a limit to the number of characters that can be typed into the filename field (259 seems to be the magic number - not sure why). We h...
I want to to create a window not sizable and without caption like vista sndvol.exe DlgSimpleVolume ...
In a nutshell: I want to do the same thing "Dependency Walker" does. Is there any Win32 API function which can enumerate the dependencies of a EXE and/or DLL file? And is there any safe way to detect dependencies on ActiveX classes? (I doubt it is possible, but who knows ...) EDIT: I'm aware of available tools which provide the same c...
I’m attempting to check the rights on a particular file for a specific trustee and am using the win32 API GetEffectiveRightsFromAcl(). When the file is accessible by a domain group, the function returns 5 (Access Denied) when a local account (admin or other) is used to execute the function. These three statements summarize the behavior...

How can I detect, or be notified, when windows is logging out in python? Edit: Martin v. Löwis' answer is good, and works for a full logout but it does not work for a 'fast user switching' event like pressing win+L which is what I really need it for. Edit: im not using a gui this is running as a service ...
In a .NET 1.0 C# application, I wish to display a list of files and folders in a listview control. I want to programmatically retrieve from windows the icons for the files or folders to display them appropriately in the list view. At present, I am using the Windows API Shell32.dll, but am having problems with the alpha channel in the ic...
Can I convert a bitmap to PNG in memory (i.e. without writing to a file) using only the Platform SDK? (i.e. no libpng, etc.). I also want to be able to define a transparent color (not alpha channel) for this image. The GdiPlus solution seems to be limited to images of width divisible by 4. Anything else fails during the call to Save()....
I'm using windbg to examine some crash dumps sent in by an app. There seems to be some correlation between a crash I'm seeing and having a certain 3rd party DLL loaded into the process (a flaky Winsock LSP, I suspect). To make this sort of analysis easier in the future, is there a windbg script that would just show me a list of modules...
