write data to the cell in excel

Hello

I am trying to write data to a cell in excel. When I'm looking in sample program, I felt a bit difficult to understand.

I have written code to read data from a particular cell that works well. I am facing difficulties in writing data in the cell. pls help someone.

to read a data cell that works

status is Excel_RangeGetItem (rangeHandle, NULL, CA_VariantInt (i + 1), CA_VariantInt (j + 1), & MyVariant);.
         
Get the pointer of SHIPPING
status = CA_VariantGetDispatch (& MyVariant, & MyDispatch);
           
Create a Range object pointer for SHIPPING
status = CA_CreateObjHandleFromIDispatch (MyDispatch, 0, & ExcelSingleCellRangeHandle);
           
Get the value of the range of simple cells
status = Excel_GetProperty (ExcelSingleCellRangeHandle, NULL, Excel_RangeValue2, CAVT_VARIANT, & MyVariant);
          
status = CA_VariantGetCString (& MyVariant, &val);)
strcpy (CellValue, Val);

to write data in a cell

status is Excel_RangeSetItem (rangeHandle, NULL, CA_VariantInt (i + 1), CA_VariantInt (j + 1), MyVariant);.
         
status = CA_VariantSetDispatch (& MyVariant, & MyDispatch);
           
status = CA_CreateObjHandleFromIDispatch (MyDispatch, 0, & ExcelSingleCellRangeHandle);
   
status = Excel_SetProperty (ExcelSingleCellRangeHandle, NULL, Excel_RangeValue2, CAVT_VARIANT, & MyVariant);
         
status = CA_VariantSetCString (& MyVariant, writedata);

I know I made a mistake in the code above.

Thank you very much, Roberto. You have solved my problem.

  • How do you return a blank in table 2, when there is no data in the cell related in table 1?

    I run a recreational League of golf and have been recording the scores of the players (50 + players in total) with the intention of maintaining a form of disability from the League.

    So far, I did most of the calculations manually in number. Recently, I have experimented using the Lookup function but have encountered a problem with the time where the player does not play this week.

    In table 1, where I do all scores record cel when they do not play is left blank. However, in table 2 than corresponding cel returns a 0... strikes completely out of whack handicaps.

    Here is what I used in table 2 for the information of table 1...  SEARCH (name, 2016 Stats::Table 1 $Last: $ name, 2016 Stats::Table 1::G44)

    I also tried to add an IF statement, but I have obviously not understood correctly as he said I tried to refer to a cel in the statement itself.

    Example of the disability Page in the table 2 list a 0 is returned in cel 6... which is then averaged in the cel of last second... namely the problem. The cel with the 6 in it is a formula that counts the number of moves played and see it 6 because it counts as a trick played 0. This shows the wrong average score of 65.666

    Hi pondball,

    (Could be my 'golf name' somedays)

    Formula in Handicap::B2 and filled to the bottom and right at Handicap::X4

    = IF (LOOKUP ($A, data: $A, Data::B)=0,"",LOOKUP($A,Data::$A,Data::B))))

    IF compared the results of the first SEARCH and if it is zero, returns an empty string. If the comparison returns FALSE, the second SEARCH is called, find and returns the result of zero. AVERAGE does not take into account all results of text, including the string NULL, a zero-length text value.

    COUNT (used in the column count the number of turns) also ignores the text values.

    4th place of disability shows one of the reasons for not using LOOKUP.

    SEARCH alwas accepts a "close fit" with the search value. 'near match' for RESEARCH is defined as 'the largest value equal or less than the value of the research', and for the values text, "less than or equal" can be described as "identical or come forward in a list of items of text in alphabetical order.»

    For us, the other two values in the name list are 'less' us and the most important is 'Them', the values for 'Them' are returned.

    For this reason, I tend to use VLOOKUP instead of RESEARCH in many cases.

    VLOOKUP present the disadvantage of requiring her research-where location which will be the first column of the lookup table (which is not a problem here, because the location of the research is one ot the column data table).

    But also has the advantage of af being able to require an "exact match" search value.

    Here's the same tables of two, with VLOOKUP replacing LOOKUP. Note that the VLOOKUP function has a different syntax than the LOOKUP function.

    Formula VLOOKUP in Handicap::B2, filled with verse down and right at Handicap::X4:

    = IF (VLOOKUP ($A, Data: $A:$ X, COLUMN (), FALSE) = 0,"", VLOOKUP ($A, Data: $A:$ X, COLUMN (), FALSE) ")

    Written as above, the formula works correctly in rows 2 and 3, but will just return the error in the 4th row triangles, since it will not find a match (exact n) for 'Us' in column A of data.

    After confirming that it produces no unexpected error, wrap the formula in function SIERREUR as shown below and repeat the filling down and the right filling operations above.

    SIERREUR function interrupt all errors, including those affecting the results without your knowledge if they occur. Always delay adding IFERROR until you know what are the errors he fools.

    =IFERROR (IF (VLOOKUP ($A, data: $A:$ X, COLUMN (), FALSE) = 0,' ", VLOOKUP ($A, data: $A:$ X, COLUMN (), F ALSE))," ")

    Y2: = COUNT (C2:X 2)

    Z2: = AVERAGE(C2:X2) (base form)

    Z2: = IF (Y = 0,' ", AVERAGE (C2:X 2)) (real form)

    The encapsulation of the AVERAGE function in the IF statement deletes the calculation if the number of items to the average value is zero, AVERAGE preventing from return to a division by zero error. The number of circles in the column there is NOT used in the calculation of the average (AVERAGE did his own count), but is used as a switch 'OK to calculate' leaving the calculation of the AVERAGE to move forward.

  • Can I limit data in the cells to a single app?

    I am considering upgrading my phone to Rabat for an iPhone. I use iOS on my iPad for several years, but have never had a smartphone before. My iPads are Wi - Fi only so I never had to worry about the limits, and since I do not anticipate needs a lot of data I expect to get a plan with a small data limit.

    I know I can say iOS does not allow the use of mobile data and only to access data via the Wi - Fi so that he does not eat my data when I don't want it.

    My question is this:

    I can say for a specific application access cellular data while blocking all other applications to do? For example, maybe I want to use an app for navigation while driving. It requires cell data for the navigation service knows where I am and you can send me instructions and alerts. But I don't want all the other apps on my phone goes on line and using data while I am using the cellular connection rather than a Wi - Fi connection.

    No matter which iPhone I get would have iOS 9.3 on it. Probably the SE of the iPhone, but I'll look older before making a final decision.

    Thank you.

    Yes - cell data can be disabled for individual applications. So you can disable it for the applications that you want to restrict and let it on-site for those who have not. I hope you enjoy your new phone

  • How do you use the freqout as the sample clock to write data on the of 6224 PCI

    Using PCI-6224, I try currently to export data using the freqout as a reference clock sample to a digital output channel. I plug the scope to see the clock on the freqout PIN. However, the data seem to be missing. How can I output the data correctly using the reference for timing? What am I missing that connects the two signals together? Any help would be greatly appreciated. I am writing this code in MS VS C++ and here's what I've done so far:

            int32       error=0;
            TaskHandle  taskHandle=0;
            TaskHandle  taskHandleFRQ=0;
            char        errBuff[2048]={'\0'};
        uInt8       data[8]={1,0,1,1,1,0,1,0};
    
        /*********************************************/
        // DAQmx Configure Clock
        /*********************************************/
        DAQmxErrChk (DAQmxCreateTask("",&taskHandleFRQ));
        DAQmxErrChk (DAQmxCreateCOPulseChanFreq(taskHandleFRQ,"Dev2/freqout","",DAQmx_Val_Hz/*Units*/,DAQmx_Val_Low/*IdleState*/,0/*Delay*/,10000/*Freq*/,0.5/*DutyCycle*/));
        DAQmxErrChk (DAQmxCfgImplicitTiming(taskHandleFRQ,DAQmx_Val_ContSamps,8));
    
        /*********************************************/
        // DAQmx Configure Digital Output
        /*********************************************/
        DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
        DAQmxErrChk (DAQmxCreateDOChan(taskHandle,"Dev2/port0/line0","",DAQmx_Val_ChanPerLine));
        DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandle,"/Dev2/PFI14",10000,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,8));
    
        /*********************************************/
        // DAQmx Write Code
        /*********************************************/
        DAQmxErrChk (DAQmxWriteDigitalLines(taskHandle,8,0,10.0,DAQmx_Val_GroupByChannel,data,NULL,NULL));
    
        /*********************************************/
        // DAQmx Start Code
        /*********************************************/
        DAQmxErrChk (DAQmxStartTask(taskHandleFRQ));
        DAQmxErrChk (DAQmxStartTask(taskHandle));
    

    I think that the original code was operational. However, given that the data transmission has been set to finished, I had a hard time to visualize the data on my scope. By changing the value of DAQmx_Val_FiniteSamps to DAQmx_Val_ContSamps, I could easily see the data.

    My mistake. I'm still learning here. Thanks for the time.

  • How to prevent the entry of the data in the cells that don't meet certain conditions

    So, the question is that I have to warn the data to enter into the cell that does not conform '< 500' condition or, on the other hand, satisfy the condition «> 500 "»

    I noticed that the link was broken.

    Here is the example:

    for (r = currentDataGrid.startRow; r)<=currentDataGrid.endRow; r++)="" {="" search="" all="">
    for (c = currentDataGrid.startCol; c)<=currentDataGrid.lastVisibleCol; c++)="" {="" search="" all="">
    Val = getCellVal (r, c); Get the value in the cell (the cube value)
    If ( <= 10="" ||="" val="">20 val) {/ / my rule to block}
    currentDataGrid.readOnly [r] [c] = 1; Block cell
    } //END IF
    } //END SECOND "FOR".
    } / / END FIRST "FOR".

    This isn't a good solution if your form is too large. I use this function while the page is loading (CustomOnLoad() I think).

  • Write data to the Source folder

    I'm trying to change part of a script that I use for work he entered into the source of a file folder, run on rather than to a specific folder (in this case, the office).  Can someone help me understand how to change and/or by adding the code below?

    create the reference to the csv file

    var file = new file (Folder.desktop + "/ Data.csv");

    Open the csv file in Add mode

    leader. Open ("e", "TEXT", "?");

    jump to the operating system in use on the line set

    ($.os.search(/windows/i)! = -1 ? file.lineFeed = 'windows': file.lineFeed = "macintosh";

    at the end of the file

    leader. Seek (0.2)

    write all the information required for the csv file

    Name of the document, Date1, database2, donnees3, etc.

    file.writeln (decodeURI (activeDocument.Name) + ","Data1","Data2","data3"," + data4. ") ToString()', '+ Data5.toString ());

    Close the csv file

    leader. Close();

    Now, I'm assuming that the part to change here is Folder.Desktop.  And I think I will need to change this option to be Folder.getFolderName.  getFolderName is a variable used in other code that checks the source directory of the current file.  This code of source directory, it's what I do not know how.  The script itself would have to do the check whenever it is running as I want him to be able to work with included subfolder of batch runs, make a new file in the subfolder when working with these files.  Anyone has any ideas, how to proceed?  Any help is very appreciated!

    Edit: I forgot to mention; It would be nice if it can also store the name of the folder in which the source file is in a variable, so it can be written to the file as .csv.  This is not as important as the code mentioned above, but it would be helpful none-the-less, if possible.

    No problem, I was able to solve it on my own all the time.  I thought it would be much harder than it actually was. but has been able to do by simply changing

    var foldLoc = new File ("C:\\Temp\\");

    var file = new file (foldLoc + "/ Data.csv");

    TO

    var foldLoc = app.activeDocument.path;

    var file = new file (foldLoc + "/ Data.csv");

    and now, it records the data and the .csv file in the same folder as the currently open project.  Thanks for trying to help; It is much appreciated.

    Dmitry,

    Well, I've been basically dealing with moving the notes at the end of the story in the correct order. Anyway, concerning the figures by exposing, there no need to choose things and remove these selections. She considered more safe, like Vamitul too mentioned, to work on the objects. To manage numbers superscript, I would do this:

    app.findGrepPreferences = null;
    // Search just the note contents: lookaround leaves the braces in the text
    app.findGrepPreferences.findWhat = /(?<=\{\{\{).+?(?=\}\}\})/.source;
    found = app.documents[0].findGrep();
    
    for (i = 0; i < found.length; i++){
        found[i].parentStory.insertionPoints[-1].contents = '\r' + String (i+1) + '.\u2003';
        found[i].move (LocationOptions.after, found[i].parentStory.insertionPoints[-1]);
    }
    
    // Now search {{{}}}
    app.findGrepPreferences.findWhat = /\{\{\{\}\}\}/.source;
    found = app.documents[0].findGrep();
    for (i = found.length-1; i >= 0; i--){
        found[i].contents = String (i+1);
        found[i].position = Position.SUPERSCRIPT;
    }
    

    Then first move the notes at the end of the story, leaving behind all the triples of braces. Then, after you have moved the notes, do you a new search on the sextets of braces. Only select and delete, just redefine the content of what you have found and apply an in shape.

    Notice that I use the operating system windows as a client and a linux as a server database

    The file will be written to the database server or your GNU / linux and I'm quite sure, there is no folder named "c:\temp" on linux. It will probably be ' / tmp' on a unix server.

    And open the file, you must give the name logic directory 'PALPROV_REPORTS' it instead of the user name "utilisateur12".
