error-checking

问题 Using the unwieldy and ponderous but full-featured Excel Interop, background error checking can be toggled off like so: Excel.Application excelApp = new Excel.Application(); excelApp.ErrorCheckingOptions.BackgroundChecking = false; ...as shown here I am getting the green triangles indicating a bad number like so: ...which I want to turn off. These are just string vals that should not be flagged as bad or suspicious. So how can I turn background error checking off for the Excel app object, or

问题 I have some large data sets that I am automating and distributing. I want to eliminate the little green triangles that warn the user about numbers stored as text. I have used the following code but it's VERY slow on massive sheets. Range(Cells(1, 1), Cells(lastrow, lColumn)).Select 'kill those dang green cell triagles Dim rngCell As Range, bError As Byte For Each rngCell In Selection.Cells For bError = 3 To 3 Step 1 With rngCell If .Errors(bError).Value Then .Errors(bError).Ignore = True End

问题 This is a simple question, but I've looked around and couldn't find the answer. How do I extract the number of affected rows from update/insert SQL queries in ZF2? The following code is working nicely for me (it does update), but I would like to perform proper error checks: public function updateSomeField($id, $some_field){ $data = array( 'some_field' => $some_field ); $sql = new Sql($this->dbAdapter); $update = $sql->update(); $update->table('Table1'); $update->set($data); $update->where

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I am doing a software that grabs in the end a numeric string, that string encodes important data, and any error destroy the contents. Worse: It is VERY prone for errors, because of how data is transmitted (and I can do nothing about it). So I decided to add a verification digit of sorts... After some research, I

问题 I'm trying to decide which one of these two options would be the best: subroutine sqtrace( Msize, Matrix, Value ) integer, intent(in) :: Msize real*8, intent(in) :: Matrix(Msize, Msize) real*8, intent(out) :: Value [instructions...] end subroutine sqtrace VS subroutine sqtrace( Matrix, Value ) real*8, intent(in) :: Matrix(:,:) real*8, intent(out) :: Value if ( size(Matrix,1) /= size(Matrix,2) ) then [error case instructions] end if [instructions...] end subroutine sqtrace I understand that

问题 I'm working on an application where users have to make a call and type a verification number with the keypad of their phone. I would like to be able to detect if the number they type is correct or not. The phone system does not have access to a list of valid numbers, but instead, it will validate the number against an algorithm (like a credit card number). Here are some of the requirements : It must be difficult to type a valid random code It must be difficult to have a valid code if I make a

问题 While reviewing Visual C++ codebase I found a following strange thing. A run-time assert (which is check the condition and throw an exception if the condition is violated ) was used in a case when the condition could be evaluated at compile time: assert( sizeof( SomeType ) == sizeof( SomeOtherType ) ); clearly the compiler will evaluate the condition and replace the code that will effectively be either assert( true ); which does nothing or assert( false ); which throws an exception every time

问题 This program is basically supposed to read data from a file, and then process that data depending on what it is. It's sort of a mock catering company, and the variables are number of adults, number of children, type of meal (deluxe or standard), type of day (weekend [Yes or No], initial deposit, etc. and the surcharge, tax, total, etc. are calculated in the CalcData function depending on what that data is (i.e. If it is a deluxe meal (D or S), the price is $25.80, instead of $21.75 (for

问题 I have just found this code to get files from the clipboard and it works fine, but I would like to make it a Boolean function so that I know it succeeded. What do I need to test to see if it has the file(s) on the clipboard and that all is OK? USES Clipbrd, shellapi; // procedure GetFileNameFromClipboard(oSL : TStringlist); function GetFileNameFromClipboard(oSL : TStringlist) : Boolean; var f: THandle; buffer: array [0..MAX_PATH] of Char; i, c: Integer; begin Result:=False; if NOT Clipboard

问题 I have 2 JTextFields: JTextField txtJobType, txtPriorityCode; This is the functionality I need: When user types in 'administration' in txtJobType and hits tab (or clicks away) an error check is done to see whether the field is empty or if the text entered exists in database. The way I have done that is: private void txtJobTypeFocusLost(java.awt.event.FocusEvent evt) { System.out.println("JobType Focus Lost"); if (!checkFieldExists(txtJobType.getText(), "jobType", "jobCode", JobType.class) ||
