У меня есть проект VB6, который использует базу данных SQL2008.Проект состоит из двух полей со списком, MSHFlexGrid и двух командных кнопок (cmdLoadSeries & cmdExit).Пользователь сделает выбор из первого поля со списком и нажмет командную кнопку cmdLoadSeries, которая заполняет второе поле со списком и сетку MSHFlexgrid.Я использую текстовое поле для управления информацией в сетке.
Первый раз, когда я выбираю строку в mshflexgrid, она выбирает / выделяет строку, по которой я щелкнул, и все, что над ней.После первого раза он только выделяет / выделяет строку, по которой я щелкнул.Зачем?Пожалуйста, помогите.
Вот мой код:
Private Sub cmdLoadSeries_Click()
Const cProcName = msModuleName & "cmdLoadSeries"
'Too save space I removed the code that retrieves MRecordSet.
If mRecordSet.RecordCount > 0 Then
LoadControls
SetFormFields True
DataCombo1.BoundText = mRecordSet2.Fields(0)
Else
LoadControls
cmdExit.Enabled = True
End If
cmdLoadSeries.Enabled = False
Combo1.Enabled = False
End Sub
Private Sub LoadControls()
Const cProcName = msModuleName & "LoadControls"
