  • Opening an Excel file in c#

    - by Jan de Jager
    So there are a lot of questions regarding this method on SO, but none seem to answer my question. I firstly had an issue with the connectionstring (although it seems to work in other areas of my code correctly). This was resolved easily. Now the issue is with a simple SELECT query via a OLEDBCommand (Text) that keeps popping up the following error? "SELECT [Opportunity#],[BidManager],[Prob %],[Opportunity_Stage].[Opportunity_Status],[Term],[Sign Date] FROM [Sheet1$];" No value given for one or more required parameters. but their are no parameters???? Checked and double checked the columns names, but to no avail. Also tried removing the special characters from the column names, but still the same exception.

  • Excel - Counting unique values that meet multiple criteria

    - by wotaskd
    I'm trying to use a function to count the number of unique cells in a spreadsheet that, at the same time, meet multiple criteria. Given the following example: A B C QUANT STORE# PRODUCT 1 75012 banana 5 orange 6 56089 orange 3 89247 orange 7 45321 orange 2 apple 4 45321 apple In the example above, I need to know how many unique stores with a valid STORE# have received oranges OR apples. In the case above, the result should be 3 (stores 56089, 89247 and 45321). This is how I started to try solving the problem: =SUM(IF(FREQUENCY(B2:B9,B2:B9)>0,1)) The above formula will yield the number of unique stores with a valid store#, but not just the ones that have received oranges or bananas. How can I add that extra criteria?

  • Mutually exclusive Checkbox in Excel (Toggle)

    - by rach-90
    I have spreadsheet with 50+ checkboxes from the forms toolbar. In a few instances you can only check 1 checkbox from a group i.e you check one checkbox from checkbox 1 to checkbox 5. I'm trying to achieve this without any code if possible. Option button is not preferred since I want an uniformed spreadsheet. How can you group the checkbox1 to checkbox5 so that they become mutually exclusive for a group. Thank you

  • Producing dynamically generated range names in Excel using c#

    - by Matey
    What is the best way to produce several tables of unknown size on the same worksheet? Values will be pulled from an oracle database and are used as values on several tables. Is it possible to create dynamic named ranges or is some other method desirable? I have some experience with c# but do not have access to VSTO 2005. Any help or suggestions would be greatly appreciated. I am willing to explain the problem further if requested.

  • Authoritative Excel range syntax reference

    - by olefevre
    Sorry if this has been asked before but I can't find it. I am looking for an authoritative description of all valid strings that can be used as a reference, e.g., "A1:C5", "$A:$A", $A2" etc etc. That seems a pretty basic thing yet I've wasted hours trying to locate it. All I can find is a swamp of "helpful" examples but no reference.

  • Excel, Pivot Calculated formula: SUM(Field1)/AVG(Field2)

    - by Bas
    I've a simple table with some amount and interval in sec by date and product name. Month | Product | Amount | Interval in sec ------------------------------------------ 05-'12| Prod A | 10 | 5 05-'12| Prod A | 3 | 5 05-'12| Prod B | 4 | 5 05-'12| Prod C | 13 | 5 05-'12| Prod C | 5 | 5 From this table I've derived a Pivot table with SUM(Amount), AVERAGE(Interval in sec) by Month and Product. Month | Product | SUM of Amount | AVG of Interval in sec -------------------------------------------------------- 05-'12| Prod A | 13 | 5 05-'12| Prod B | 4 | 5 05-'12| Prod C | 18 | 5 So far So good... Now i want to add and extra column to my Pivot table with gives me the outcome of SUM of Amount / AVG of Interval in sec Adding a calculated value =SUM(Amount)/AVERAGE(Interval) is not giving me the right values. Exel gives me. Month | Product | SUM of Amount | AVG of Interval in sec | Amount per sec ------------------------------------------------------------------------- 05-'12| Prod A | 13 | 5 | 1.3 05-'12| Prod B | 4 | 5 | 0.8 05-'12| Prod C | 18 | 5 | 1.8 What it actually is doing is =SUM(Amount)/SUM(Interval in sec) for every Month and Product based on the values in the first table... But I'm looking for Month | Product | SUM of Amount | AVG of Interval in sec | Amount per sec ------------------------------------------------------------------------- 05-'12| Prod A | 13 | 5 | 2.6 05-'12| Prod B | 4 | 5 | 0.8 05-'12| Prod C | 18 | 5 | 3.6 So litterly devide pivot field 'Sum of Amount' by pivot field 'AVG of Interval in sec' How to achieve this? Thank you in advanced

  • Prevent Excel from evaluating unneeded expressions in OR()

    - by Wesley
    IF(OR(ISNA(MATCH(8,B10:B17,0)),MATCH(8,B10:B17,0)>8),"",...BLAH...) I understand how to fix this problem by rearranging my formula. I have it the way it is to show this point. You can see the OR() statement checks to see if the first MATCH() returns NA. When it does, OR() should automatically return TRUE and not evaluate the second MATCH() because conditions have been met for the OR() to return true no matter what other arguments there are. You'll notice that the first and second MATCH() functions do the same thing. What's happening is the entire function is returning NA because the second MATCH() is executing even though it doesn't have to, the OR() has been satisfied with one TRUE, therefore the function should return "". Is this a bug or is this intentional?

  • Exporting to CSV/Excel in Java

    - by WIOijwww
    I'm trying to export data into a CSV file through Java and I've got some code to do it but it doesn't seem to be outputting the CSV file. Could someone tell me what's wrong? What I would like to do is rather than saving the file somewhere, I would like it to be directly exported to the user. EDIT: Just in case it's not clear, I don't want the file to be saved anywhere but would like it to be outputted automatically to the user i.e. they click export and get the "Run/Save results.csv" window and they open the file. Currently the file is getting saved so I know that the method seems to work, just in the opposite way that I want it to. public static void writeToCSV(List<Map> objectList) { String CSV_SEPARATOR = ","; try { BufferedWriter bw = new BufferedWriter(new OutputStreamWriter( new FileOutputStream("results.csv"), "UTF-8")); for (Map objectDetails : objectList) { StringBuffer oneLine = new StringBuffer(); Iterator it = objectDetails.values().iterator(); while (it.hasNext()) { Object value = it.next(); if(value !=null){ oneLine.append(value.toString()); } if (it.hasNext()) { oneLine.append(CSV_SEPARATOR); } } bw.write(oneLine.toString()); bw.newLine(); } bw.flush(); bw.close(); } catch (UnsupportedEncodingException e) { } catch (FileNotFoundException e) { } catch (IOException e) { } }

  • It's easy to set a breakpoint when debugging VBA, but how about a "startpoint" or a "skippoint"?

    - by PowerUser
    I'm debugging a subroutine in my VBA code. I want to ignore the first half and just run the second half. So, is there a way to set a 'startpoint'? Also, is there an easy way to ignore a specific line of code other than commenting? If not, I'll just continue commenting out all the code I don't want run. The problem with this, of course, is that I have to remember to uncomment the critical code before I send it on to Production.

  • Word VBA: How to know if the actual save operation is completed?

    - by Edwin
    Hi, I am having a problem with the Document.SaveAs method in Word VBA with large Word documents, it seems that the save operation is asynchronous, ie. after calling SaveAs it returns immediately, but with large Word documents the actual save operation may not has been completed and it's in progress in another thread. So what I want to ask is that if there is a way to detect if the actual save operation is in progress or finished? PS. I use Delphi to call the automation interface of Word, if it means something in discussing this problem, but I don't' think so? Thank you in advance.

  • Alternatives to Project Euler for improving Excel ability

    - by Jonathan Deamer
    I've recently been enjoying using the mathematical problems listed at Project Euler to learn Python. My Excel ability is better than my Python, but I think I'd still benefit from the sort of inductive learning that comes with solving a series of increasingly difficult puzzles using a particular tool. I know Project Euler can be completed using Excel, but are there any other puzzle series similar to this or The Python Challenge specifically tailored for people trying to increase their knowledge of Excel and what it can do? NB. I'm not looking for a "tutorial", I know there are plenty of these. And apologies if this isn't completely appropriate for programmers.SE.com - some of the folks at SuperUser suggested it was a better fit here than there!

  • Excel 2013 Data Explorer and GeoFlow make 3-D maps quick and easy

    - by John Paul Cook
    Excel add-ins Data Explorer and GeoFlow work well together, mainly because they just work. Simple, fast, and powerful. I started Excel 2013, used Data Explorer to search for, examine, and then download latitude-longitude data and finally used GeoFlow to plot an interactive 3-D visualization. I didn’t use any fancy Excel commands and the entire process took less than 3 minutes. You can download the GeoFlow preview from here . It can also be used with Office 365. Start by clicking the DATA EXPLORER...(read more)
