  • Spreadsheet::WriteExcel Memory Usage

    - by Stomped
    Hi; I'm trying to create a multi-sheet excel document, and thus far I'd been doing it in PHP - but using PHPExcel was eating up 70MB of RAM for about 60,000 spreadsheet cells total. I'm wondering if anyone has experience with Spreadsheet::WriteExcel and if it has problems with creating very large documents. I'd just give it a shot but I'm very inexperienced with Perl and it could take me quite a bit of time to get this up and rolling even if for a test, and I thought someone here might have insight for me.

  • If/Then in SQL Embedded in VBA

    - by Daniel
    I've got a string like this in my Excel VBA: strSQL = "SELECT * FROM Total WHERE (SimulationID = (" & TextBox1.Text & ") And Test1 = (" & Example & "))" However, sometimes Test will be 'is null', which makes the query And Example = is NULL How can I change it to add an if/then statement or something to make it say And Example is null when Example has a value of "is null"?

  • Microsoft VC++ 2005 SP1 and 2008 SP1 Redistributable Package

    - by ewlung
    Dear developers, I have an application that requires Microsoft VC++ 2005 (SP1) Redistributable Package. I know that I can just download it and install it. The problem is, in our server, there is Microsoft VC++ 2008 (SP1) Redistributable Package already installed. Now, do I still need to install the 2005 (SP1) version? Or the 2008 (SP1) is "backward compatible" with 2005 (SP1)? Thank you.

  • normalize data to scale from 1 to 10

    - by Matjaz Lipus
    I have a following data set: A B N 1 3 10 2 3 5 3 3 1 3 6 5 10 10 1 20 41 5 20 120 9 I'm looking for an excel function that will normalize A and B to N on scale from 1 to 10. In above example it would be 1 of 3 is best so N = 10 2 of 3 is in the middle N = 5 3 of 3 is worst N=1 20 of 120 is in second decade N=9 A = 1 && A <= B B is natural number 1 <= N <= 10

  • Improving performance on data pasting 2000 rows with validations

    - by Lohit
    I have N rows (which could be nothing less than 1000) on an excel spreadsheet. And in this sheet our project has 150 columns like this: Now, our application needs data to be copied (using normal Ctrl+C) and pasted (using Ctrl+V) from the excel file sheet on our GUI sheet. Copy pasting 1000 records takes around 5-6 seconds which is okay for our requirement, but the problem is when we need to make sure the data entered is valid. So we have to validate data in each row generate appropriate error messages and format the data as per requirement. So we need to at runtime parse and evaluate data in each row. Now all the formatting of data and validations come from the back-end database and we have it in a data-table (dtValidateAndFormatConditions). The conditions would be around 50. So you can see how slow this whole process becomes since N X 150 X 50 operations are required to complete this whole process. Initially it took approximately 2-3 minutes but now i have reduced it to 20 - 30 seconds. However i have increased the speed by making an expression parser of my own - and not by any algorithm, is there any other way i can improve performance, by using Divide and Conquer or some other mechanism. Currently i am not really sure how to go about this. Here is what part of my code looks like: public virtual void ValidateAndFormatOnCopyPaste(DataTable DtCopied, int CurRow) { foreach (DataRow dRow in dtValidateAndFormatConditions.Rows) { string Condition = dRow["Condition"]; string FormatValue = Value = dRow["Value"]; GetValidatedFormattedData(DtCopied,ref Condition, ref FormatValue ,iRowIndex); Condition = Parse(Condition); dRow["Condition"] = Condition; FormatValue = Parse(FormatValue ); dRow["Value"] = FormatValue; } } The above code gets called row-wise like this: public override void ValidateAndFormat(DataTable dtChangedRecords, CellRange cr) { int iRowStart = cr.Row, iRowEnd = cr.Row + cr.RowCount; for (int iRow = iRowStart; iRow < iRowEnd; iRow++) { ValidateAndFormatOnCopyPaste(dtChangedRecords,iRow); } } Please know my question needs a more algorithmic solution than code optimization, however any answers containing code related optimizations will be appreciated as well. (Tagged Linq because although not seen i have been using linq in some parts of my code).

  • 2nd Year College - Learning - Microsoft Server Products

    - by Ryan
    As the title says, I just finished my first year of college (majoring in Software Engineering). Fortunately my school likes Microsoft enough, and I can get pretty much anything I want that Microsoft sells. I also can get IBM Websphere and the like for free as well. Earlier this year, I set up an oldish computer (2.6 Pentium D, x64) to run ubuntu server headless. I'm predominately a Java developer, so Apache, Maven, Nexus, Sonar, SVN, etc made it onto the machine. It worked really well for personal and school projects, especially team projects (quick ramp up). Anyways, I started to pick up C# to complement my Java knowledge (don't judge me :P), and am interested in working with some of the associated Microsoft equivalents. The machine currently has the Ubuntu install, as well as Windows 7 Ultimate. I do all of my actual development work off my laptop, also running Windows 7 Ultimate. I was wondering what software you would recommend putting on the machine. I’m not actually serving anything off the machine itself, but in Ubuntu I had it doing integration tests with Hudson on every commit, and profiling my applications, etc, etc. The machine would be running headless, and I would remote into it. Here is what I am currently leaning towards / wondering about: Windows 7 Ultimate vs Windows Server 2008 (R2) (no one is really clear why I should go with one over the other) Windows Team Foundation Sharepoint (Never used it before, kind of meh about it) IBM Websphere or Glassfish (Some Java EE web server) SQL Server 2008 A DVCS In order to better control product conflicts / limit resource use, I’m wondering if I should install things into virtual machines (I can get VmWare or Microsoft Virtualization Products) I also plan on installing everything I had running under Linux (it’s almost entirely Java based development software, so it’ll run on both, only reason I went with ubuntu during the year was because the apache build seemed better). I’m primarily looking to become familiar with enterprise software development tools, as well as get something functional that will help my development process. (IE, I’ll still use project and assign tasks even though I might be the only one to assign tasks to, just to practice doing so). Is there any other software / configuration details I should explore? Opinions on my current list? I primarily use C#, Java, and PHP. I'm familiar with ruby, and python as well. Thanks!

  • How to get points that intersect the treadline?

    - by chutsu
    Basically I did the Cavendish experiment, and I have a damped sinusoidal wave plotted on Excel. With Position (mm) against Time (s). My problem is that I have added a tread line through the wave function, and wish to calculate the points of which the wave function intersects the tread line. From this I will then be able to calculate the time period. At the moment I'm just having difficulty getting the intersects.. Thanks

  • (Pivot) tables generation

    - by Yasir Arsanukaev
    Hello. We use Excel VBA to load data using SQL, process it and generate (pivot) tables. I wonder if there any other decent alternatives. I've been thinking on PDF generation but not sure if there are handy tools to construct pivot tables. Important requirement is the ability to print data correctly, so that everything fits on the page(s). Thanks.

Typically the user would be pasting anywhere between 150 to 300 spreadsheet cells that are all in one column. What are some good ways i could use to capture this data on the web page? thanks

  • What is the current status on Microsoft ProClarity?

    - by Ali_Abadani
    I don't really know how to compose this question. My complay has been using Microsoft ProClarity for few years and we have a quite a few users using it publising books and doing ad-hoc analysis. With the new Microsoft BI solutions, it seems like they are completely going away from ProClarity and replacing the OLAP analysis with Excel. I understand the with SharePoint and integration with PerformancePoint and reporting services the dashboards and reports would be done in SharePoint but what about the analysis? Any ideas?
