问题 I have some code I previous got from one of my other Access Databases, which works fine. It intended purpose was to copy the results that were put into a make table into a blank excel sheet then format the columns. I however copied the code and tweaked it a little. What I am trying to do with the copied code is still export my results into a blank excel sheet, however, this time I am not coping from a make table but from a select query. I am not sure if it is possible but there is no other

问题 Needing assistance on performing a format check. Ok so what I have now is a button on my access form that exports the results into a new blank Excel file when clicked. What I am trying to accomplish now is add some code that checks if Fields 6-10 added together <> field 5 throughout the WHOLE dataset then performing conditional formatting and highlight the ones that aren't the same as yellow. Once this is in place, Then I would like a message box to appear and however many items that are

问题 Creating an access database for work. Users will use a split form with only the datasheet visible to review and manipulate numeric data. On the form I have built in quick filters that consist of of textboxes in which the values are either raised or lowered with arrow buttons that have on-click events. I currently have the text boxes linked to the recordsource query criteria. With all of this stated, the problem that I am having is that I need the filter to act in the following manner: If the

问题 I got a table called "dbInventory" with "ID, InvName, InvQuantity, InvType" and a entry form matching these columns. What I'm trying to achieve is to have the listbox start displaying search results based on the input. (My ID column contains barcodes, not autonumbers) So for instance, if I scan a barcode for an item I already put in the table some other time, I would like it to appear on the listbox right away. How would one go about that? 回答1: It seems like you are wanting to deal with two

问题 I have two tables that have different data that I need to merge. They do have similarities such as: Order number, Name, type or product. But they have separate data as well like: Order date, and Engravings. Would I do two separate Append queries in Access into a merged table? Or one Append queries? Or just keep the data separate? I am new to Access and trying to find the best way to approach this. 回答1: Merging the two tables into one completely defeats the purpose of using a database and you

问题 I have a table in MS-Access that needs to contain an array of 4 (type number) values. At the moment they are in named fields, VAL1, VAL2, VAL3, VAL4. However, that’s cumbersome (the number of values may be larger) because I want to use a loop in the associated VBA code, which generates a binary data file from the database tables. Is it possible for VBA to access table fields using raw index values? As an example, if I have a table with the following fields: Name VAL1 VAL2 VAL3 VAL4 Can I

问题 I'm trying to connect to and read many hundreds of MS Access database files using the "RODBC" package in RStudio (32 bit). The previous program used to open and read these files used and system.mdw system database file to specify user permissions, but I can't find anything in the RODBC documentation that describes how to include this file in the connection string. Here is what I've tried, which has succceded in connecting to the database, but failed to read any of the contents: files <- dir(
