I have some data that is displayed in a pivot table, from that pivot table I currently copy and paste them in another table with the corresponding current day, with so many operation numbers it takes about 1hr to complete this process daily, I'm trying to make a macro in which will help me in making this process in less time
This is the pivot table in which I copy the data
and here is where I paste it (in this table I use it to create some graphs)
Both tables consist of many different numbers of operation, as you can imagine this is very tedious.
Any help or ideas that can help me solve this is appreciated, I'm willing to try some other alternatives like fomulas, vba (preferred), even closedxml for c#.
I dont know if im explaining my self?
This is my logic.
Look for operation number
Copy Sum of "Sx"
Look in other sheet for the same operation number.
Paste value in corresponding day.
Look for same operation number with next "Sx"
.
.
End
Right now I'm just focusing on Operation1, since in Operation2 I use another sheet in which I do the same thing. (will probably use the same code as Operation1).
To clarify I'm not asking for someone to just give me the solution (although it is appreciated ), but any guide on this is helpful.
You do not need VBA to do this. Use GETPIVOTDATA.
Consider below replicated data:
In above sample, I copied some of your data in your screen shot, made a pivot out of it, put it in the same sheet and also put the table you need to populate below it. Then I use GETPIVOTDATA. I feel I need to show you how it is done even though it is well explained in the link I posted.
So we use this formula:
=GETPIVOTDATA("Sum of "&$I18,$I$2,"Date",J$17,"Opt",$I$16,"Id",$J$16)
in Cell J14. Take note that instead of using Day 1, Day2.. etc on your destination table, we used the actual date. Why? Because we need that in our GETPIVOTDATA Formula. Then copy the formula to the rest of the cells.
Result:
Now, GETPIVOTDATA errors out if it does not find anything which matches the criteria you supplied, so you might want to incorporate error handling using IFERROR statement.
Final Formula:
=IFERROR(GETPIVOTDATA("Sum of "&$I18,$I$2,"Date",J$17,"Opt",$I$16,"Id",$J$16),0)
Although you prefer VBA, I don't think a better approach than the built-in Excel functionality is more suitable in your case.

Let's say I have two fields (one under another). By default I want to have both of them rendered, but when the first field is empty, I would like the second one to take its place. Is there any convenient way to achieve this?
Note: My problem is much more complex, and a "scalable" solution would be highly appreciated.
I've found a cumbersome method, but I'm still looking for something better.
I finally came up with a better solution. The solution is to create a table in a DataSet, and insert a subreport selecting the table as its data source. Now you can add rows dynamically to the table (depending on some conditions).
For reasons that don't make a lot of sense (Read: Not my decision) I need to keep a large number of rows, about ~90,000, in a DataTable and I do not have the option of using a database.
I need to be able to search the DataTable efficiently to find rows that match some basic criteria. For example, I might be looking at a row that has the value 2 in two specific columns.
What is the best way to do this?
Edit: Please take a look at https://chat.stackoverflow.com/transcript/message/62648#62648 for more details; after I work on this I will try and summarize the extra details from the chat here as well as provide my solution.
You could easily use DataTable.Select()
The solution I ended up using for this painfully awkward and inconvenient situation was to use DataTable.Select(), populate a new DataTable and then use the same operation to select the rows I needed from the refined DataTable.
I think that this solution is clumsy, but then again the constraints on the problem were somewhat unrealistic seeing as I was on a tight schedule as well.
I am working on program that calculate the GPAs for university students in C#.
I have made a gridview that contains columns for each subject. Its mark as letter and
number. After the user "student" insert his/her subject I want to let the user click a
button that will get the mark and the number of the credit hours of each subject. Calculate the GPA for the student and put the result in a textbox.
I am having trouble getting started. Any advice for a good place to start?
To answer just the question in your title:
To get value from the current row, first capture the row:
DataGridViewRow r = MyDataGridView.CurrentRow;
To get the value from cell 0:
string v = (string)r.Cells[0].Value;
What I see from your question you are having difficulty how to put the requirement in one place.
I'm assuming you already have the user requirements (it looks very simple) and I give basic steps you go through, it is not accurate and it doesn't fit for all type of projects, but your case is very simple and I think it is enough to do the work.
first you will need to create a flow, the steps the user will go through to accomplish the process.
then you will need the basic interface to let you have at least to know what controls you will need.
after that you will make the data structure (mostly the database schema) to know how the data will be stored and related to each other.
then you will create the business logic to implement your requirements.(the coding part)
and Last you will glue all the things and attach the code that wrote to the events in the interface based on the flow you made it at the first step.
I hope this helps.
I'm not sure about what you are trying to do, but you can take a look here:

I've solved lots of my WPF dumb design problems with these articles :P
Long story short, the database I'm using needs to get looked at. Until that happens, I need to make do with what I've been given (I know, I should fix it..).
I have a table that get populated via an external text file. I am not sure of the exact process as I'm relatively new to the company.
The table does not have a primary key as the entire table is dumped and re-loaded every quarter when there is a new text file.
Enter ASP.NET MVC. I need to display that table with checkboxes in a grid so the user can select some rows and send it back to the server. It sounds relatively easy, but I am really not sure what to put as the value for the checkboxes as I am pretty sure I'll need to use multiple columns to create a unique. Yep, I know, I know :).
OldTable
- Field1
- Field2
- Field3
...
- FieldN
The View
...
<input type="checkbox"
name="bunchOfStuff"
value"Field1Value,Field2Value,Field3Value"/>
...
Would something like this work? If I can create a key with a few fields, can I use those fields as the value in the checkbox? I realize my action will be a bit ugly as I'll have to split and parse each value in the array of values.
Wow, good luck with this!
I think your solution will certainly work and I can't think of a more elegant solution.
However I think you're going to be in deep trouble down the line. The thing that I would do would to be simply to put a Unique Identifer on the table that auto increments.
That shouldn't affect any of your processes or even your bulk insert application unless you insert using an ordinal field offset rather than named.
Sorry this answer isn't exactly what your looking for but the DB is just so bad that (any) answer presented I think will be equally bad.
There is about 2000 lines of this, so manually would probably take more work than to figure out a way to do ths programatically. It only needs to work once so I'm not concerned with performance or anything.
<tr><td>Canada (CA)</td><td>Alberta (AB)</td></tr>
<tr><td>Canada (CA)</td><td>British Columbia (BC)</td></tr>
<tr><td>Canada (CA)</td><td>Manitoba (MB)</td></tr>
Basically its formatted like this, and I need to divide it into 4 parts, Country Name, Country Abbreviation, Division Name and Division Abbreviation.
In keeping with my complete lack of efficiency I was planning just to do a string.Replace on the HTML tags after I broke them up and then just finding the index of the opening brackets and grabbing the space delimited strings that are remaining. Then I realized I have no way of keeping track of which is the country and which is the division, as well as figuring out how to group them by country.
So is there a better way to do this? Or better yet, an easier way to populate a database with Country and Provinces/States? I looked around SO and the only readily available databases I can find dont provide the full name of the countries or the provinces/states or use IPs instead of geographic names.
Paste it into a spreadsheet. Some spreadsheets will parse the HTML table for you.
Save it as a .CSV file and process it that way. Or. Add a column to the spreadsheet that says something like the following:
="INSERT INTO COUNTRY(CODE,NAME) VALUES=('" & A1 & "','" & B1 & "');"
Then you have a column of INSERT statements that you can cut, paste and execute.
Edit
Be sure to include the <table> tag when pasting into a spreadsheet.
<table><tr><th>country</th><th>name></th></tr>
<tr><td>Canada (CA)</td><td>Alberta (AB)</td></tr>
<tr><td>Canada (CA)</td><td>British Columbia (BC)</td></tr>
<tr><td>Canada (CA)</td><td>Manitoba (MB)</td></tr>
</table>
Processing a CSV file requires almost no parsing. It's got quotes and commas. Much easier to live with than XML/HTML.
/<tr><td>([^\s]+)\s\(([^\)])\)<\/td><td>([^\s]+)\s\(([^\)])\)<\/td><\/tr>/
Then you should have 4 captures with the 4 pieces of data from any PCRE engine :)
Alternatively, something like http://jacksleight.com/assets/blog/really-shiny/scripts/table-extractor.txt provides more completeness.
Sounds like a problem easily solved by a Regex.
I recently learned that if you open a url from Excel it will try and parse out the table data.
If you are able to see this table in the browser (Internet explorer), you can select the entire table, right click & "Export to Microsoft Excel"
That should help you get data into separate columns, I guess.
do you have to do this programatically? If not, may i suggest just copying and pasting the table (from the browser) onto MS Excel and then clearing all formats? This way tou get a nice table that can then be imported into your database without problem.
just a suggestion... hth
An assembly exists for .Net called System.Xml; you can just reference the assembly and convert your HTML document to a System.Xml.XmlDocument, you can easily pinpoint the HTML node that contains your required data, and use the use the children nodes to add into your data. This requires little string parsing on your part.
Load the HTML data as XElements, use LINQ to grab the values you need, and then INSERT.
Blowing my own trumpet here but my FOSS tool CSVfix will do it with a combination of the read_xml and sql_insert commands.
