IamlaosongDiscover a phenomenon that When the application.calculation is automatically calculated, the 2003 version does not seem to reduce the speed of VBA, but the 2007 version has a significant impact and is particularly noticeable when the data is large, especially when the volume is high, and the speed reduction is unbearable. To do this, you must change the application.calculation state to Manual mode, and then restore it at the end of the run.
IamlaosongWhen using VBA to process Excel files, the key fields of the column number programming is often not known, need to pass parameter settings to know, therefore, when we program, we can not use such a statement to take the number of valid rows:Lineno = [B65536]. End (Xlup). RowThe column name "B" in the above statement, if it is a variable, can be implemented in the form of a string connection, namely:pos_ems = "C"Lineno = Range (pos_ems "6553
IamlaosongWhen the Excel file is processed with VBA, the column number of the keyword segment is often not known when programming. Need to know by the number of parameters, so. When we program, we cannot use this statement to take a valid number of rows:Lineno = [B65536]. End (Xlup). Row ' find valid rows from bottom to topThe column name "B" in the above statement is assumed to be a variable. Can be implemented in the form of a string connection, nam
IamlaosongLooking at a simple loop program, after VBA reads the data from the database, you need to enter a summation formula in the last cell:The formula means cells (i, 9) = Cells (I, 6) + cells (i,7) +cells (I, 8), where rc[-3] represents the formula in the same row The first 3 columns of the cell.How do I represent the first 3 rows in the same column? Very simple, with r[-3]c on it. And so on, the same row after three columns is rc[3], the curre
Although I have said earlier, it is not a good idea to manipulate a workbook in VBA, but sometimes it is unavoidable to do so. In the vast majority of cases, what we want to do is get a workbook object and use it to get the sheet object, and then process the data in the worksheet. The latter part (the action sheet) has been discussed earlier, so this chapter is about how to open, close, and describe two commonly used workbook objects in
