wpf - Modify Connection Strings the first time I run the app -


i want provide feature opens dialog first time program opens , allow system admin change application connection strings.

so far, haven't had success in doing so.

  • i can't use user settings. want users connect same database.
  • the application settings read-only.
  • seems can't modify app.config file , save physical disk. far can tell, changes applied memory.
  • i thought writing them different file program might run uac issues.

how can save these strings file , access them? prefer use app.config because entity framework contexts can initialized using connection string names.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
