问题 I am using SetLayeredWindowAttributer to make a particular color of layered window transparent. This works fine on Windows XP,VISTA . But when I use the same on Windows 7 its not working. SetLayeredWindowAttributes(hWnd, RGB(0xff,0xff,0xff), 0, LWA_COLORKEY); When I use LWA_ALPHA then also it works. Problem is that I am not able to make a particular color transparent in Windows 7. The following statement works on Windows 7 SetLayeredWindowAttributes(hWnd,RGB(0xff,0xff,0xff), 100, LWA_ALPHA);

问题 I am trying to capture proxy setting ("Automatically Detect Settings"). My code works on XP and Vista. But it is NOT working on Windows 7 Please see the details of target platform Windows 7 Enterprise, IE 8.0.7600.16385, Wininet.dll 8.0.7600.16535 Please see the code snippet INTERNET_PER_CONN_OPTION_LIST List; INTERNET_PER_CONN_OPTION Option[1]; unsigned long nSize = sizeof(INTERNET_PER_CONN_OPTION_LIST); Option[0].dwOption = INTERNET_PER_CONN_FLAGS; List.dwSize = sizeof(INTERNET_PER_CONN

问题 I have a very basic problem, but I cannot find a solution in older answers. When I double click on a python script, I can see a prompt flashing but nothing happens. If I open the same script with IDLE and run it, everything works fine. To be sure the script was not executing propoerly, I made a test script like this: def main(): files = open('test.txt','a') files.write('this is a test') The simple script write the file if launched thru idle, but nothing happens if if I double click it. I

问题 I am new to Windows programming and I'm trying to discover the best way to check for the existence of Windows Shell API functions. I want to use some of the new taskbar features in Windows7. https://msdn.microsoft.com/en-us/library/dd378460%28VS.85%29.aspx#custom_jump_lists But I still want my program to be usable by previous versions of Windows. Is there an easy way to know if the functions are available to be called in the end users system. I'm programming in C++. 回答1: It depends on the

问题 I'm using D2010 under Windows 7 to write an app that seems to require admin rights (I think because it uses COM to communicate with a third party .exe, which also requires admin rights). I've added the manifest resource as required, but when I try to debug the app from the IDE, it reports "Unable to create process. The requested operation requires elevation" ...and it won't run. If I run Delphi as administrator, then my app runs correctly, but this feels like a dangerous brute force approach,

问题 I am using the WPF OpenFileDialog and SaveFileDialog in my .NET 4 WPF application. I use the Filter property to allow the user to set different file filters. In .NET 4, this uses the native file dialogs introduced with Windows Vista (if possible). However, these dialogs show the extensions which make up the file filters. Since some of these use quite a bit of extensions, this is quite ugly. For example, I have a filter Image files|*.bmp;*.dib;*.jpg;*.jpeg;*.jpe;*.jfif;*.gif;*.tif;*.tiff;*.png

问题 I am working on a LAN based solution with a "server" that has to control a number of "players" My protocol of choice is UDP because its easy, I do not need connections, my traffic consists only of short commands from time to time and I want to use a mix of broadcast messages for syncing and single target messages for player individual commands. Multicast TCP would be an alternative, but its more complicated, not exactly suited for the task and often not well supported by hardware.

问题 I'm running my Java program from command-line (Windows 7). To simplify matters, I describe only the relevant part. public static void main(String[] args) { System.out.println("Árpád"); } My output is garbage. It is obviously a character-encoding problem, the Hungarian characters of Á and á are not showing up correctly. I've tried the following: public static void main(String[] args) { PrintStream ps = new PrintStream(System.out, true, "UTF-8"); ps.println("Árpád"); } But my output is still

问题 Im running on a Intel computer (Win7 64-bit) and according to what I read Intel is using Little-Endian. I try this out in C# with the following code: byte[] b2 = new byte[] { 0, 1 }; short b2short = BitConverter.ToInt16(b2, 0); and b2short == 256 as expected from a Little-Endian. Then I read that in .NET, the BitConverter.IsLittleEndian should reflect what endian the system is using, and when I check the variable in Visual Studio it reports false , ie it is NOT Little-Endian. Does that have

问题 I am trying to load a .dll file and have it display a message box when loaded. From my understanding, once a .dll is loaded, it makes a call to dllmain() and switches to the DLL_PROCESS_ATTACH option. I have written the code for both the .dll and the .exe which loads it. The .exe can load it correctly and print out the address in which the dll has been loaded, but I do not see a message box being displayed. I read somewhere on Microsoft.com that the dll enters a "lock" when loaded as to
