VBA #112298

Кто знает каманду Попытка Исключение, но тока на VBA? Подскажите плиз...

on error goto n

On Error GoTo <Метка> - при ошибке перейти к строке с меткой On Error Resume Next - при ошибке продолжать выполнение On Error Go To 0 - отменить обработку ошибок Из обработчика ошибки Resume Next - выйти из обработчика и продолжить выполнение со след оператора

На VB.NET этот изврат ликвидировали.

On Error Statement       Enables an error-handling routine and specifies the location of the routine within a procedure; can also be used to disable an error-handling routine. Syntax On Error GoTo line On Error Resume Next On Error GoTo 0 The On Error statement syntax can have any of the following forms: Statement Description On Error GoTo line  Enables the error-handling routine that starts at line specified in the required line argument. The line argument is any line label or line number. If a run-time error occurs, control branches to line, making the error handler active. The specified line must be in the same procedure as the On Error statement; otherwise, a compile-time error occurs. On Error Resume Next Specifies that when a run-time error occurs, control goes to the statement immediately following the statement where the error occurred where execution continues. Use this form rather than On Error GoTo when accessing objects. On Error GoTo 0 Disables any enabled error handler in the current procedure. Remarks If you don't use an On Error statement, any run-time error that occurs is fatal; that is, an error message is displayed and execution stops. An "enabled" error handler is one that is turned on by an On Error statement; an "active" error handler is an enabled handler that is in the process of handling an error. If an error occurs while an error handler is active (between the occurrence of the error and a Resume, Exit Sub, Exit Function, or Exit Property statement), the current procedure's error handler can't handle the error. Control returns to the calling procedure. If the calling procedure has an enabled error handler, it is activated to handle the error. If the calling procedure's error handler is also active, control passes back through previous calling procedures until an enabled, but inactive, error handler is found. If no inactive, enabled error handler is found, the error is fatal at the point at which it actually occurred. Each time the error handler passes control back to a calling procedure, that procedure becomes the current procedure. Once an error is handled by an error handler in any procedure, execution resumes in the current procedure at the point designated by the Resume statement. Note   An error-handling routine is not a Sub procedure or Function procedure. It is a section of code marked by a line label or line number. Error-handling routines rely on the value in the Number property of the Err object to determine the cause of the error. The error-handling routine should test or save relevant property values in the Err object before any other error can occur or before a procedure that might cause an error is called. The property values in the Err object reflect only the most recent error. The error message associated with Err.Number is contained in Err.Description. On Error Resume Next causes execution to continue with the statement immediately following the statement that caused the run-time error, or with the statement immediately following the most recent call out of the procedure containing the On Error Resume Next statement. This statement allows execution to continue despite a run-time error. You can place the error-handling routine where the error would occur, rather than transferring control to another location within the procedure. An On Error Resume Next statement becomes inactive when another procedure is called, so you should execute an On Error Resume Next statement in each called routine if you want inline error handling within that routine. Note   The On Error Resume Next construct may be preferable to On Error GoTo when handling errors generated during access to other objects. Checking Err after each interaction with an object removes ambiguity about which object was accessed by the code. You can be sure which object placed the error code in Err.Number, as well as which object originally generated the error (the object specified in Err.Source). On Error GoTo 0 disables error handling in the current procedure. It doesn't specify line 0 as the start of the error-handling code, even if the procedure contains a line numbered 0. Without an On Error GoTo 0 statement, an error handler is automatically disabled when a procedure is exited. To prevent error-handling code from running when no error has occurred, place an Exit Sub, Exit Function, or Exit Property statement immediately before the error-handling routine, as in the following fragment: Sub InitializeMatrix(Var1, Var2, Var3, Var4)    On Error GoTo ErrorHandler ErrorHandler: Here, the error-handling code follows the Exit Sub statement and precedes the End Sub statement to separate it from the procedure flow. Error-handling code can be placed anywhere in a procedure. Untrapped errors in objects are returned to the controlling application when the object is running as an executable file. Within the development environment, untrapped errors are only returned to the controlling application if the proper options are set. See your host application's documentation for a description of which options should be set during debugging, how to set them, and whether the host can create classes. If you create an object that accesses other objects, you should try to handle errors passed back from them unhandled. If you cannot handle such errors, map the error code in Err.Number to one of your own errors, and then pass them back to the caller of your object. You should specify your error by adding your error code to the vbObjectError constant. For example, if your error code is 1052, assign it as follows: Err.Number = vbObjectError + 1052 Note   System errors during calls to Windows dynamic-link libraries (DLL) or Macintosh code resources do not raise exceptions and cannot be trapped with Visual Basic error trapping. When calling DLL functions, you should check each return value for success or failure (according to the API specifications), and in the event of a failure, check the value in the Err object's LastDLLError property. LastDLLError always returns zero on the Macintosh.

Офф: Интересно, а будет ли VBA.NET?

Еще вопрос! Как ComboBox1 при активизации формы сделать по умолчанию значение 1 из списка... так оно пустое..

Ну что никто не знает?

Попробуй,не помню: ComboBox1.Text ComboBox1.Value и поэкспериментируй со свойством ComboBox1.MatchRequired=(True,False)

+8 ComboBox1.ListIndex=0,1,....ListCount

а что у тебя Ф1 выкушена из клавиатуры? Посмотри справку там много чего есть...

'Add list entries to combo box. The value of each    'entry matches the corresponding ListIndex value    'in the combo box.    ComboBox1.BoundColumn = 0                'Set combo box to first entry

Всем большое спасибо!
