我是Excel VBA的新手。我需要使用以下vlookup公式在excel工作表中执行vlookup：
=INT(IFERROR(VLOOKUP(A:A,[sheet.xls]Sheet1!B:F,5,FALSE),0))
谁能指导我使用VBA来应用此vlookup
答案 0 :(得分：0)
基本方法：

private ExoPlayer.EventListener eventListener = new ExoPlayer.EventListener() {
@Override
public void onTimelineChanged(Timeline timeline, Object manifest) {
Log.i(TAG,"onTimelineChanged");
}
@Override
public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) {
Log.i(TAG,"onTracksChanged");
}
@Override
public void onLoadingChanged(boolean isLoading) {
Log.i(TAG,"onLoadingChanged");
}
@Override
public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
Log.i(TAG,"onPlayerStateChanged: playWhenReady = "+String.valueOf(playWhenReady)
+" playbackState = "+playbackState);
switch (playbackState){
case ExoPlayer.STATE_ENDED:
Log.i(TAG,"Playback ended!");
//Stop playback and return to start position
setPlayPause(false);
exoPlayer.seekTo(0);
break;
case ExoPlayer.STATE_READY:
Log.i(TAG,"ExoPlayer ready! pos: "+exoPlayer.getCurrentPosition()
+" max: "+stringForTime((int)exoPlayer.getDuration()));
setProgress();
break;
case ExoPlayer.STATE_BUFFERING:
Log.i(TAG,"Playback buffering!");
break;
case ExoPlayer.STATE_IDLE:
Log.i(TAG,"ExoPlayer idle!");
break;
}
}
@Override
public void onPlayerError(ExoPlaybackException error) {
Log.i(TAG,"onPlaybackError: "+error.getMessage());
}
@Override
public void onPositionDiscontinuity() {
Log.i(TAG,"onPositionDiscontinuity");
}
};

值得一看的是.FormulaR1C1属性，这在VBA中可能更为明确。如果您不使用FormulaR1C1语法，请注意绝对/相对地址。
myRange.Formula = "=INT(IFERROR(VLOOKUP(A:A,[sheet.xls]Sheet1!B:F,5,FALSE),0))"
如果您不知道如何使用VBA进行操作，请使用Macro Recorder。它的输出糟糕透顶，始终需要清理，但精通后，您会在5秒钟内得到答案，这是一种易于学习的工具。
最终，在一个单元格中手动输入公式-在X2中输入-然后在“即时”窗口中，键入mySheet.Range("X2").Formula = "=INT(IFERROR(VLOOKUP($A:$A,[sheet.xls]Sheet1!$B:$F,5,FALSE),0))"
（或Print range("x2").Formula）以查看要放入代码中的确切公式。 / p>
