• Export to Excel in Asp.net MVC

  - by BigJoe714

  I am working on an ASP.NET MVC application where I need to export data to an excel spreadsheet. Previously, in webforms apps, I used some code I found to render a GridView as an excel-compatible file. This was quite handy. I was wondering what the quickest/most effective method would be to do this in MVC. Thanks.

• OleDBDataAdapter UNPIVOT Query not working with Microsoft.ACE.OLEDB.12.0 DataSource

  - by JayT

  I am reading in an excel file with an OleDBDataAdapter. I am using a select statement to UNPIVOT the data and insert into DataSet. However, the compiler is genereating this error: {"Syntax error in FROM clause."} But the SQL Statement is correct as I have used it in other DB's Here is the code: string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + FileName + ";Extended Properties=\"Excel 12.0 Xml;HDR=" + HDR + ";IMEX=1\""; OleDbConnection conn = new OleDbConnection(strConn); conn.Open(); string SQL = "select Packhouse, Rm, Quantity , Product " + " FROM " + " ( " + " SELECT Date,Packhouse, Rm,[FG XL], [FG L] " + " FROM [" + xlSheet + "] " + " ) Main " + " UNPIVOT " + " ( " + " Quantity FOR Product in ([FG XL], [FG L]) " + " ) Sub " + " WHERE (Date = '2010/03/08') and Quantity <> '0' and Packhouse = 'A' and Rm = '1' "; OleDbDataAdapter adapter = new OleDbDataAdapter(); adapter.SelectCommand = new OleDbCommand(SQL, conn); ds[sequencecounter] = new DataSet(); adapter.Fill(ds[sequencecounter], xlSheet); If I copy and paste the excel data into a DB, then the select query works, but the data presented to me is in excel spreadsheets. If anyone could provide help on this it will be much appreciated. Regards, J

• Worksheet.Unprotect - Office Interop - Difference between 2003 and 2007

  - by sdmcnitt

  I have a .NET winforms app that automates Excel and checks for a worksheet password. The requirements are to be able to detect 1) that the protection is turned off 2) that the password is removed (protected but there is no password) 3) that the password matches the correct password from a database To meet the second requirement the program calls the Worksheet.Unprotect command with a null string, capturing the error. If error as expected, the 3rd check is made. If no error, then the Unprotect worked without a password == password was removed. The code sample below has these checks. The application can do this fine with Office 2003. I have since had my dev machine updated to Office 2007 and it no longer works as it did. When I call the Worksheet.Unprotect, Excel prompts for the password! I need to know how this should be accomplished in the new version of Excel or if there is a way to reference the old PIA. No matter what if I set a reference to Excel 11 it is replaced with the PIA for 12 in the GAC. 'return true if unprotect of worksheet does not generate an error 'all other errors will bubble up 'return false if specific error is "Password is invalid..." Try 'detect unprotected or no password If oWorksheet.ProtectContents Then 'try with no passsword and expect an error 'if no error then raise exception Dim blnRaiseException As Boolean = True Try 'oWorksheet.Unprotect(vbNullString) oWorksheet.Unprotect() Catch ex As Exception blnRaiseException = False End Try If blnRaiseException Then Throw New ExcelSheetNoPasswordException End If oWorksheet.Unprotect(strPwd) 'no error so if we get here -- success fnCheckWorksheetPwd = True 'leave as it was -- this may still cause workbook to think it is changed oWorksheet.Protect(strPwd) Else Throw New ExcelSheetNotProtectedException End If Catch COMex As System.Runtime.InteropServices.COMException 'handle error code -2146827284 If COMex.ErrorCode = -2146827284 Then 'this is the error we're looking for Else Throw End If Catch ex As Exception Throw End Try

• mscomctl.ocx on my dev machine gives me problems since security patch of MS

  - by Bronzato

  I am busy on this problem since 2 days ago and hope someone can get me out of it. I have Excel 2010 (full install 944Mb) on my Windows 8 computer. It works well. But when I modify my workbook (containing a ListView version 6.0) I am not able to run it on my client's computer. I get the error: Could Not Load An Object. Not Available on This Machine. Even it works well on my dev machine. The reason is: Microsoft applied a Security Patch (near august 2012 I think) on mscomctl.ocx and my Excel 2010 installation files (downloaded not long ago) contains the new version of mscomctl.ocx. The clients using my Excel file don't apply the security patch at this moment. Se everytime I publish my Excel file to client's computers (from my dev environment), I reference the new mscomctl.ocx. That's the problem. I already try to get the old mscomctl.ocx from client's computer and copy & register it on my dev machine but then I got errors (Class not registered, ...) when I create a userform and drag a listview on it. So: mscomctl.ocx on client's machine is version 6.1.98.13 from 2008. mscomctl.ocx on my dev machine is version 6.1.98.34 from 2012. My question: Does someone have an idea how to proceed to have a usable version of mscomctl.ocx on my dev machine? Thank you very much.

• how to insert excel-2003 values into SQL2005 database?

  - by vas

  Are there any rules / guidelines for DATA form XLS sheets to be inserted into SQL- DB? I have a group of Excel templates in 2005.Each concerned cell in Excel template is named. When Excel sheets are filled, saved and submitted , the values are transferred to the database. Excel sheets have names for various cells that are to b e filled by the user EX:- for the total number of Milk in the Beginning a given month , there is an Excel Cell Named "mtsBpiPTR180" Total number of Milk in the Ending a given month , there is an Excel Cell Named **"mtsEpiPTR180"** I have added 2 new cells , named "mtsBpiPTR180PA" and "mtsEpiPTR180PA". Now I try to upload the Excel File. But I AM UNABLE TO SEE MY FILLED DATA FROM "mtsBpiPTR180PA" and "mtsEpiPTR180PA" INTO THE RELATED DB/table. The above 2 are empty in the DB/table, even though I have filled them and successfully filed the Excel sheets Now no matter how much I search in the DB/stored procs i am unable to the ACTUAL STORED PROC or how the Data form Excel sheet is inserted into Tables WHERE DATA FROM XLS is inserted into DB. So was wondering:- Are there any rules / guidelines for DATA form XLS sheets to be inserted into SQL- DB?

• Find a non-case-sensitive text string within a range of cells

  - by Iszi

  I've got a bit of a problem to solve in Excel, and I'm not quite sure how to go about doing it. I've done a few searches online, and haven't really found any formulas that seem to be useful. Here's the situation (simplified just a bit, for the purpose of this question): I have data in columns A-E. I need to match data in the cells in A and B, with data in C-E, and return TRUE or FALSE to column F. Return TRUE if: - The string in A is found within any string in C-E. OR - The string in B is found within any string in C-E. Otherwise, return FALSE. The strings must be exact matches for whole or partial strings within the range, but the matching function must be case-insensitive. I've taken a screenshot of an example sheet for reference. I'm fairly sure I'll need to use IF or on the outermost layer of the formula, probably followed by OR. Then, for the arguments to OR, I'm expecting there will be some use of IFERROR involved. But what I'm at a loss for is the function I could most efficiently use to handle the text string searches. VLOOKUP is very limited in this regard, I think. It may be workable to do whole-string against whole-string comparisons, but I'm fairly certain it won't return accurate results for partial string matches. FIND and SEARCH appear limited to only single-target searches, and are also case-sensitive. I suppose I could use UPPER or LOWER to force case-insensitivity in the search, but I still need something that can do accurate partial matching and search a specified range of cells. Is there any function, or combination of functions, that could work here? Ideally, I want to do this with a straight Excel formula. I'm not at all familiar with VBScript or similar tools, nor do I have time to learn it for this project.

• Outlook receives winmail.txt attachment instead of Excel, PowerPoint or Word attachments from Lotus notes senders

  - by Philippe

  Ok so the title pretty much says it all. We are offering a Hosted Exchange solution for our customer. Everything is working fine except for one customer complaining that he is receiving winmail.dat or winmail.txt attachments instead of the actual Word Excel or PowerPoint attachments he should be receiving, only when these messages come from a specific European senders, that is using Lotus Notes. I know that usually the problem is coming from Outlook senders to other mail clients, but this is not the first they inform me of this but I can't find anything on the matter so far. Has anyone ever gotten and solved this problem? If not, does anyone have any idea regarding this? I had solved this problem a few months ago, by upgrading Outlook to SP2 and then uninstalling it using the Service Pack removing tool of Microsoft. It seems that only the latest SP1 version could work but not the SP2. The problem is that now nothing is working at all. Thank you for your help, Philippe

• How to tell if Microsoft Works is 32 or 64 bit? Please Help!

  - by Bill Campbell

  Hi, I am trying to convert one of our apps to run on Win7 64 bit from XP 32 bit. One of the things that it uses is Excel to import files. It's a little complicated since it was using Microsoft.Jet.OLEDB.4.0 (Excel). I found Office 14 (2010) has a 64bit version I can download. I downloaded Office 2010 Beta but it didn't seem to install Microsoft.ACE.OLEDB.14.0. I found that I could download 2010 Office System Driver Beta: Data Connectivity Components which has the ACE.OLEDB.14 in it but when I try to install it, the installed tells me "You cannot install the 64-bit version of Access Database engine for Microsoft Office 2010 because you currently have 32-bit Office products installed". How do I determine what 32bit office products this is reffering to? My Dell came with Microsoft Works installed. I don't know if this is 32 or 64 bit. Is there anyway to tell? I don't want to uninstall this if it's not the problem and I'm not sure what else might be the problem. Any help would be appreciated! thanks, Bill

• Microsoft Excel 2010 How to reference a table to another sheet

  - by Shiro

  I am using Excel 2010. I got a sheet name "March" I would like to duplicate it (with reference / link) to another sheet called "Summary" which included January, Feb, and March. In the summary tab I would add another column called "Month" and will duplicate the value "March" or their tab month. I did some research on it, they said copy and paste special with link, but I can't find it. I need to reference the whole table, just in case any change add / remove the row of the table, the summary still will update it. Is there any solution with this? Thanks!

• Inserting a very long Excel table into Word

  - by Fred

  I have a very long excel (2003) s/sheet with in excess of 600 rows that I want to paste into an MS Word document (also 2003). However, I want to ensure that: 1) The header row appears automatically at the top of each page. 2) The s/sheet automatically formats to the correct page width (the one I have is slightly wider than my Word page). This can obviously be done manually by cutting and pasting each page seperately but this is very laborious and time consuming and I once saw somebody achieve this automatically (maybe with a macro) but have been unable to locate them, or the methodology. Can anyone please assist? Thanks in advance, Fred.

• File in use when it's really not

  - by C-dizzle

  I am running Windows 7 Professional 32 bit on a Server 2008 network. I am getting a weird issue with an excel document where I open it up one morning, update it, save and close, the next morning I come in, open it up and it says "This file is in use and locked by csmith" which "csmith" is me! So I click on the cancel button, open it up again and it comes up fine. I can edit, save and close with no problem. But then have the same issue the next morning. Another weird thing is that we have a calendar shared in "Public Folders" under Outlook that seems to be having the same issue, which happens to be a calendar made in Excel. Exchange 2010 is installed on the server and the clients are using Exchange 2007. In the instance with the calendar, it will show conflicting edits have been made and you must keep one item or all items. And it shows an edit date of 4/24/2012 and 6/1/2012. But, there were NO edits done on 6/1, just tried opening it. This problem does not occur under my profile, but 2 others. These machines are ALSO running Windows 7 Professional 32 bit. We have a mix of Windows 7 and Windows XP machines on our network if that is any help. These issues did not start happening until we migrated from a server running Server 2003 and Exchange 2000, which the new server is running Server 2008 and Exchange 2010 as stated above. Is there something on the server side that is configured wrong?

• Is it possible to have a conditional formatting cell "visually cycle" through all the formats that evaluated true?

  - by Ben

  Like the title says, "In Excel, when a cell has multiple conditional formatting rules that evaluate true, is it possible to have the cell "visually cycle" through all the formats that evaluated true? If not, suggestions on what to do would be appreciated!" I'm creating an employee schedule for a business that has multiple job areas that need to have an employee assigned to cover. The schedule is currently set up with the date on the top row, employee list down the left column, and the employee's assigned "job area" cross-referencing with the date on the top row. Originally it was set up where if every required "job area" didn't have someone assigned to it, the date would (via conditional formatting) change to red. I've set it up now that if a condition isn't met, the date will change to the color of the "job area" that doesn't have an employee assigned to it. However, there are cases where multiple job areas don't have an employee assigned, but the date will only change color based on the first condition that isn't met. It'd be nice if there was some way for the date cell to cycle through the different colors that correspond to the job areas where no one is assigned. I have a hunch that's not possible though. If it is possible, I'd love to know how to do it. And if it isn't, if anyone has any suggestions on how I can modify the Excel sheet to make it easier to identify the job areas that don't have anyone assigned to them, I would appreciate it. FYI This schedule goes out months in advance.

• Change date in a SQL query to reference a cell in Excel

  - by Adil

  I have the following code that returns the needed data into excel and manually changing the date will change the returned data; however, I'd like to reference a cell with a formula that will make the query a bit more user friendly. I've tried using my limited knowledge of referencing a cell but none have worked. This information is in cell A1 and the query is placed in cell A2 with the following equation: =wwQuery("STKAP03", $A$1) SET QUOTED_IDENTIFIER OFF SELECT * FROM OPENQUERY(INSQL, "SELECT DateTime, [40_MOTORS.MI436423.CIN], [40_MOTORS.MI436425.CIN] FROM WideHistory WHERE [40_MOTORS.MI436423.CIN] IS NOT NULL AND wwRetrievalMode = 'Delta' AND wwVersion = 'Latest' AND DateTime >='20120409 07:00:00' These two dates/times I'd like to reference cells on a different sheet AND DateTime <= '20120416 07:00:00'")

• Excel IP address and subnet to network and inverse mask [closed]

  - by Steve Dailey

  We need a script, marco or something in excel where we can take list like below interface Vlan100 ip address 192.168.1.3 255.255.255.0 interface Vlan101 ip address 192.168.2.3 255.255.255.128 interface Vlan102 ip address 192.168.2.130 255.255.255.128 interface Vlan103 ip address 192.168.3.3 255.255.255.240 etc... and produce a list like below ospf 1 undo silent-interface Vlan-interface100 undo silent-interface Vlan-interface101 undo silent-interface Vlan-interface102 undo silent-interface Vlan-interface103 area 0.0.0.0 network 192.168.1.0 0.0.0.255 network 192.168.2.0 0.0.0.127 network 192.168.2.128 0.0.0.127 network 192.168.3.0 0.0.0.15 so it will need to take an ip address/subnet mask and convert them to network number/inverse mask. I believe I can handle the Vlan manipulation with a substitution so no need to spend time on that.

• Converting a DWG/DXF to CSV or Excel

  - by Menno Gouw

  I'm using ZWcad and i need to get the coordinates of hundreds of blocks into a excel sheet or .CSV file so i can import that into the GPS hardware. I know there are plenty of tools for autocad, i probably can even write one myself but as far as ZWcad goes i seem to be out of options. However ZWcad saves to DWG too, and exports to all the other familiar cad extensions. So i was wondering if i would just save the blocks i need to export to a certain file there might be a tool/program to convert that directly into .CSV.

• Pivot Table grand total across columns

  - by Jon

  I'm using Excel 2010 and Power Pivot. I'm trying to calculate confidence and velocity for a development team. I'm extracting some information from our time and defect system each day and building a data set. What I need to do with Excel is do the calculations. So each day I add to my data set 1 row per task in the current project, estimate for that task and the time spent on that task. What I want to calculate is the estimate/actual for each task but also for each person. The trouble is that each day the actual is cumulative so I need to pick out the maximum value for each task. The estimate should remain unchanged. I can make this work at the task level with a calculated measure (=MAX(worked)/MAX(estimate)) but I don't know how to total this up for a person. I need the sum of the max worked for each task. So a dataset might look like: Name Task Estimate Worked N1 T1 3 1 N2 T2 3 1 N3 T3 4 1 N1 T1 3 2 N2 T4 5 1 N3 T3 4 2 N1 T5 1 2 N2 T6 2 3 N3 T7 3 2 What I want to see is for task T1 2 days were worked against an estimate of 3 days - so 2/3. For person N1 I want to see that they worked a total of 4 days against an estimate of 4 days so 4/4. For person N2 they worked 5 days for an estimate of 10 days. Any ideas on how I can achieve this?

• Spreadsheet application that can handle big data OS X

  - by Peter

  I've been working with Excel for quite a while for some statistical analysis that I do regularly. The size of the data that I'm working with has gotten much larger as of late, however. The layout of the databases in question is quite simple, usually just three rows which includes a UNIX timestamp, and EST value, a proprietary numeric value and finally an average of the rows that have a timestamp +/- 1000 that row's timestamp (little AVERAGEIFS() formula). That formula and the EST conversion are the only formulas in the sheet. I'm beginning to work with files with 500,000+ rows. Running the average formula down the entire row takes forever. The end result is the production of print-worthy graphs. I'm looking for either a UNIX CL utility or separate spreadsheet/database application that can handle this amount of data without melting my CPU or making me wait an hour. Is there anything out there? TL;DR: Simple excel sheet with over half a million rows is getting too slow to work with. OS X alternatives?

  I'm curious what the requirements are for Excel Calculation Services in Sharepoint 2010. I found an architecture document but it doesn't list out the specific requirements. (architecture I understand that you can install all the services on one server but it isn't recommended. It then talks about how you can scale up the application servers, and web front ends. What should the hardware look like for both the application server and web front ends? Do I need to setup a standalone box for each application server?

• How to use the outcome of a formula as the value for Vlookup or another IF formula

  - by Steven

  Ok I will try to explain my issue effectively. I am making a GPA sheet in which the value out of 100 is computer in to a GPA value and then in to a letter. In cell N5 i have the value of all their grades (formula: =H3+H4+H5) Now in cell (j6) I have a formula which is giving them a number depending on the value calculated in N5 (Formula: =IF(AND(N5>=60,N5<=63.999),"2.0",IF(AND(N5>=64,N5<=66.999),"2.25",IF(AND(N5>=67,N5<=69.999),"2.4",IF(AND(N5>=70,N5<=73.999),"2.5",IF(AND(N5>=74,N5<=76.999),"2.75",IF(AND(N5>=77,N5<=79.999),"2.9",IF(AND(N5>=80,N5<=83.999),"3.0",IF(AND(N5>=84,N5<=86.999),"3.25",IF(AND(N5>=87,N5<=89.999),"3.4",IF(AND(N5>=90,N5<=93.999),"3.50",IF(AND(N5>=94,N5<=96.999),"3.75",IF(AND(N5>=97,N5<=100),"4",IF(AND(N5<=59.999),"0"))))))))))))) Still no problem... as the values I was looking for comes out (example 84.2 shows up as 3.25 as I wanted). However here comes the problem.... I have tried to use the outcome in J6 to do Vlookup or another if formula, however excel does not seem to recognize the value in J6. For example: =VLOOKUP(j6,B3:C15,2,FALSE)... this returns N/A however if I enter =VLOOKUP(3.25,B3:C15,2,FALSE) it gives me what im looking for. It seems that excel will not register the outcome of my formula as a number. What can I do please?

• How can I check cells for number series?

  - by Stephen Younger

  I have a bit of a problem evaluating an excel cell. Example: M M M M M M M M M 1 2 3 4 5 6 7 8 9 2;5;7 1;9 3;5;7;9 I have a number of excel cells which contain numbers (months). In the first column I have a series of numbers. I want to use conditional formatting to color the corresponding cells in the right columns. If correctly colored I would get something like this: M M M M M M M M M 1 2 3 4 5 6 7 8 9 2;5;7 X X X 1;9 X X 3;5;7;9 X X X X The formula I have now is this: IF(ISNUMBER(FIND(L$22;$K23));$H23;"") but the problem is that cells are colored too which contain part of a number. If I enter 10;15 as input I get this: M M M M M M M M M M M M M M M 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 10;15 X X X X because 1 and 5 are found too. I only want column 10 and 15 to be marked. How can I change the formula or the input?

  Any help is appreciated: I'm developing a C#.Net app in VS2010 that interacts with Excel. The app works correctly on my local machine. Uploading to a remote Windows 2003 server however, breaks the app. Originally, I received the following message Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 After Googling the problem (which suggested a permissions problem) i tried this: Installing Excel 2007 Going into Component Services on the remote server and following the instructions here: http://blog.crowe.co.nz/archive/2006/03/02/589.aspx Now I get this message on the same operation: Exception from HRESULT: 0x800A03EC Google searches seem to be suggesting that this is a version match error.
