问题 There seems to be a bug with the Windows 7 batch file 'for' command. This command can walk through a source directory and return one filename at a time. But I found that if my command modify the files in that source directory e.g. for /R %1 %%s in (*.*) do call :do1file %%s @goto :EOF :do1file @echo es > tmp_x2932.tmp move /y tmp_x2932.tmp %1 @goto :EOF the 'for' command could invoke the do command with the same file name more than 1 times. (Note that, for the purpose of illustrating the

问题 I have installed the latest versions of R (2.15.2) and Java (7.11), and through RStudio (0.97.310) I am trying to load the rJava package. It seemed to install properly, but when I call library(rJava) I get the following error: Error : .onLoad failed in loadNamespace() for 'rJava', details: call: stop("No CurrentVersion entry in '", key, "'! Try re-installing Java and make sure R and Java have matching architectures.") error: object 'key' not found Error: package/namespace load failed for

问题 how to Create Windows 7 Quick Launch Icon With C# ? 回答1: Create a .lnk file in the c:\users\mumble\appdata\roaming\microsoft\internet explorer\quick launch folder. Beware that the Quick Launch toolbar is disabled by default in Win7, I don't remember what I did to re-enable it. Creating the .lnk file takes secret sauce as well.

问题 This question provides a fast way to use the kernel.dll to recursively find file attributes, e.g. file names. The problem is reporting progress (such as in a Windows Forms App) is limited to which file or directory it is currently on as it has no information as to total file count upfront. Though, I know in Windows 7 if you use the file explorer to search for a file, it shows a progress bar for the search: So how is it they do it here? Is total file count known here ahead of time? Is it

问题 I have a form, which sets these styles in constructor: this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.ResizeRedraw, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); And I draw some rectangles in Paint event. There are no controls on the form. Hovewer, when I resize the form, there are black strips at right and bottom of the form. Is there any way to get rid of them? I've tried everything,

I cannot modify the Path variable from Start->Computer->Properties->Advanced System Settings->Environment Variables, etc. because Windows cannot find systempropertiesadvanced.exe (since the path is empty). So I want to set the path using the setx command from cmd.exe. But I get the error that setx is not a recognized command (probably because the path is empty). So where is the setx command

问题 Windows 7 (and probably Windows Vista) display localized folder names using the LocalizedResourceName entry in the desktop.ini file. For my Documents folder, this looks like [.ShellClassInfo] LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21770 IconResource=%SystemRoot%\system32\imageres.dll,-112 IconFile=%SystemRoot%\system32\shell32.dll IconIndex=-235 (see this question) This way the explorer displays the path "C:\Users\Username\Documents" as "C:\Benutzer\Username\Dokumente" on a
