MySQL does not use double quotes but single quotes, and even still the other single quote is not there to match it. The single … Read more
In anticipation that it will be needed, here is how you get all the digits of a number. long value = Long.MAX_VALUE; System.out.println(value); while (value != 0) { // get the remainder when divided by 10 int digit = (int) (value % 10); System.out.print(digit + ” “); // now divide value by 10 to position … Read more
If you simply want to call the IsRectangle() function, just add the following code between the next: and } lines: if (IsRectangle(x1, y1, x2, y2, x3, y3, x4, y4)) { printf(“The points define a rectangle.\n”); } else { printf(“The points do NOT define a rectangle.\n”); } However, as others have pointed out, there are a … Read more
Ok now I get what want to achive. To wrap it and center horizontally (I assume you want to do it) you need to margin: 0 auto; to .container NOTE: there will not be any scroll horizontal because of position: fixed; TIP: If you create css do tree of selectors in this case .rectangle{} and … Read more
You can get the executing assembly path. string path = (new System.Uri(Assembly.GetExecutingAssembly().CodeBase)).AbsolutePath; From there, you can obtain the drive letter (path root): string drive = Path.GetPathRoot(path); If your file is in the same directory as the executable, you can get the file path like this: string directory = Path.GetDirectoryName((new System.Uri(Assembly.GetExecutingAssembly().CodeBase)).AbsolutePath); string databaseFile = Path.Combine(directory, “filename.dbf”); … Read more
Since you say you know Java, why not write a Java program that provides the GUI, and then runs the python script? I’m pretty sure Java can run external programs solved Python – Make a GUI for an existing script [closed]
The first parameter to fputs is a char*, so the code you show is obviously incorrect. You say I tried itoa or sstream functions but it’s not working. but those are the solutions, and there’s no reason for them not to work. int a = 5; //the C way FILE* pFile = fopen(“myfile.txt”,”w”); char buffer[12]; … Read more
Because you didn’t reference the variable using an object reference in your validClientId() method (as described by T McKeown’s answer), your code is looking within the scope of the validClientId() method itself to find that variable. It can’t find it because the variable hasn’t been declared within that scope. Try including the object reference as … Read more
It’s of type FontStyle i.e. Enums are first class types. public enum FontStyle { Regular = 0; Bold =1; Italic = 2 } // No need to cast it FontStyle fontstyle = FontStyle.Bold; Edit: Perhaps you have code like this: if(1 == 1) FontStyle fontstyle = FontStyle.Bold; for your error (Embedded statement cannot be a … Read more
After creating a new keystore, will I have to generate new keys for Google Maps and Facebook by pointing to the newly generated keystore? Case 1 If you are using the debug.keystore and signing the build from debug.keystore then you will see that hashkey will change if you sign the same application from another system … Read more
This kinda works. I can think of a couple of cases where something like this would break, like if the arrays were like {9,9,9} and {9,9,9}, result would be {9,9,8} instead of {1,9,9,8}. It’s a minor fix that is being left as an activity to the reader. public static void main(String []args){ int[] number1 = … Read more
If you just want to open an existing image using defualt app then use ShellExectue API. For example: ShellExecuteW(NULL, L”open”, L”Z:\\cat.PNG”, NULL, NULL, SW_SHOW); You could also open image with mspaint using the same API: ShellExecuteW(NULL, L”open”, L”C:\\Windows\\system32\\mspaint.exe”, L”Z:\\cat.PNG”, NULL, SW_SHOW); ShellExecuteEx will let you wait for finishing process. You can do the same using … Read more
“Stack overflow” means that your recursive function calls itself too many times than the system can support it. Either you have an error, and recursion goes to infinity, or the function is correct, but just needs the depth that system currently can’t provide. We cannot tell which of the two is it until we see … Read more
Your approach is correct and will work as well. Just you need to wrap it into a function. Another way is using ^ (Bitwise XOR) to do that functional and more clean: function toggleNumber( $num ) { return $num ^= 1; } Online Demo That function gets the number and does XOR with 1 on … Read more
well the syntax was wrong, that’s all. It should be public static int CalculateAge(this DateTime bornDate). No dot between this and DateTime. But you absolutely need this when declaring an extension method, as every bit of documentation describing extension methods will say… – Jon Skeet solved DateTime does not contain a defintion for the method … Read more
