问题 I am getting the java.lang.SecurityException: Permission denied: file:////Videos/public/scripts/screenshot.jar when I try to use an applet. Here is the applet code: <applet code="Screenshot" archive="file:////Videos/public/scripts/screenshot.jar" width="100px" height="100px"> </applet> I've signed the applet using this 3-step guide, but it doesn't seem it worked for me, as I am still getting the error. http://www.narendranaidu.com/2007/11/3-easy-steps-to-self-sign-applet-jar.html 回答1: Your

问题 I cannot resolve this problem and I am here for help. When I try to export my android project to apk in eclipse (any way - by exporting signed or unsigned application project) I'm receiving an error - "Failed to export application Command-line Error -1073741816 ". I have all the tools provided from google (SDK, ADT etc. from this one package - http://developer.android.com/sdk/index.html ). I read here that this is a java 7 problem - so, I reinstalled it to java 6, changed settings in eclipse

问题 In kernel : I am reading the time value as type extern s64 Latency; In user space : extern double latency; //fp is reading the kernel value (i.e Latency) fscanf (fp,"%lf", latency); If I read s64 from kernel as double in the user space. Is there possibility of data loss ?? which data type should I use to get the complete value ?? 回答1: The short answer: Yes, there will definitely be data loss. Think about it, both a signed 64 bit integer ( s64 ) and a double has 64 bits of storage. But whereas

问题 I have a thick Java client that is launched as jnlp. The jars are all signed. this application works on all OSes except on Mac OSX 10.5.8. Using Safari or FireFox, when I launch the app, I get the following error: java.lang.NullPointerException at java.util.jar.JarVerifier.mapSignersToCodeSource(JarVerifier.java:496) at java.util.jar.JarVerifier.mapSignersToCodeSources(JarVerifier.java:508) at java.util.jar.JarVerifier.getCodeSources(JarVerifier.java:826) at java.util.jar.JarFile

问题 I am making an application and on the "front" page of the Tab I get the signed_request. But when I navigate to different pages on the app it stops providing the data. So far this work: $signed_request = $facebook->getSignedRequest();<br /> $user_profile = $facebook->api('/me');<br /> echo $user_profile['id'];<br /> echo $user_profile['name']; echo $_SESSION['signed_request']; // Returns the data But when I navigate to other pages, it doesn't give anything. It looses everything. How can I keep

问题 When I learned two's complimentary, I was taught, that for a signed number, 0111 represents 7 , so by using two's complementary, 0111 -> 1000 + 1 -> 1001, is -7 so 1001 represents -7 . While I refreshed this concept on YouTube, I see a video that is saying, 0000 0111 represents 7 , so by using two's complementary, 0000 0111 -> 1111 1000 + 1 -> 1111 1001, is -7, thus, 11111001 represents -7 . I got confused. So by just looking at a signed binary number, how can we determine its value? I

问题 I have a value thats 5 bits in length. 4 bits determine the number and the 5th bit determines the sign, there by holding any value between -16 and +15. How can I accomplish sign extending from a constant bit width in C#? I know in C, I can use something like the follow to accomplish this: int x; // convert this from using 5 bits to a full int int r; // resulting sign extended number goes here struct {signed int x:5;} s; r = s.x = x; How can I do something similar to this in C#? 回答1: It's not

问题 I came across this question in a forum. The answer is something like this: #define ISUNSIGNED(a) (a >= 0 && ~a >= 0) //Alternatively, assuming the argument is to be a type, one answer would use type casts: #define ISUNSIGNED(type) ((type)0 - 1 > 0) I have a few questions regarding this.Why do we need to check ~a >= 0 ? What is the second solution all about? I did not understand the statement: "argument is to be a type". More importantly the author states that first #define will not work in

问题 I use Cordova 5.0.0 to develop android app and I would like to run the app on real machine. I tried two ways to generate signed apk but failed, One is used command line to sign an apk that generated by cordova. by this way, it will cause "parsing error" when install the apk; The second way I tried is using android studio to generate signed apk. My step is "import non-android studio project" then generate signed apk. By this way, I install successfully but the app can't be open and popup error

问题 Short description : I have a signed driver that passes SignTool verification but Windows refuses to load it with error: CodeIntegrity 3004 - file hash not found on system. How do I fix this? Long description : I'm using the Cypress Suite USB 3.4.7 development kit to create a USB driver for our instrument to run under Windows 7 64-bit. I've configured the INF with the proper IDs and the unsigned driver works fine as long as I by bypass driver signature enforcement. I want to create a signed
