• CVI - Course excel files open "windows in.

  Hello

  I'm working on a project en CVI (8,0), who must deal with Excel files.

  The problem is that my software don't control the file which is open: its name and its location are not known normal program.

  My idea is to browse excel files open, to verify the presence of the characteristic for some characters in.

  Normal however, I can't seem to find the fonctionns allowing me to browse these files in the Excel API.

  My idea would be for example:

  Lancer Excel (se connecter, avec le Excel_ActiveApp )
  POUR chaque fichier ouvert FAIRE
       Lire contenu case 'A1'
       Si contenu == "toto" ALORS
          // C'est mon fichier
      SINON
          // C'est pas mon fichier
      FIN SI
  FIN POUR
  

  I tried searching with

  Microsoft Excel 14.0 object library

  and

  Microsoft Excel 9.0 Object Library

  I have not found.

  So I'm looking for help,

  Thanks in advance,

  Cédric.

• Check if excel workbook open ActiveX and get workbook reference

  Hello

  I want to read data into the first worksheet in an excel workbook, regardless of its State:

  (1) open

  (2) closed

  .. without all of the guests.

  Closed is the easy part, because the workbook is not open.

  If the work folder is open and you try to open it to get a reference, it is says something like "workbook is already open. Open again will abort the changes. »

  Question of the day: how to get a reference to a workbook already open without asking to Excel? Assuming that I have JUST referred to the Excel application.

• More than 1 file open Excel, Aero Peek will show not miniature, only circles

  Since the critical update from Microsoft last week (26/02/13), when I have more than one file opened in Excel, all I get in the vignettes are circles.  I restored in time before the update and the Aero Peek normally carried out with more than one Excel file is open.  The feature works with more open file in Word, MapPoint and Outlook (all open at the same time).  If there is only a single Excel file open, the Aero Peek thumbnail runs as it should.  The file names appear again, but only spinning circles on the tile.

• Combine several excel worksheet in an excel file

  Hello

  I'm using labview in 2011 and I don't have the tolkit of report generation. My software create 3 or 4 excel files separately. Is there a way to combine all those who Excel in an excel (take the spreadsheet of all the excel files and merge them together into the new excel file...)

  Can't find a way to do it... No function is to do.

  Thank you

  Eric

  You do that your spreadsheet with historical data is not the active worksheet? That would erase your previous test data and put the new test data in its place.

  The simplest approach is a workflow similar to this:

  (1) check if Excel file exists

  1A) If this is the case, create a new worksheet

  1 (b) if it is not, create a new Excel workbook

  (2) adding data

  (3) save the report

  (4) report close

  The report generation tool has screws that do everything most of these functions. To check if the file exists, it is in a separate palette.

• The download window - behavior on the selection of the Excel window open excel files

  Imagine that you are working on an Excel file. You have completed and saved. You leave open and want to download it via Firefox - whether for a portal, or to send an email or anything else.
  As soon as any Excel file is selected in the window of the Explorer/upload (be it by single click or highlighting by the arrows), Excel window is set up to forward - as if I had clicked on the icon in the taskbar.

  I can't make pile or face of this - it seems to be only Excel.
  It's pretty frustrating in itself and especially when needing to download several Excel files.

  Any ideas?

  Guigs2, you understand.

  COR - el, Yes, it happens only when Excel is already running. He does not Excel if Excel is not running.

  Update: now it no longer. I have no idea what has changed. I have probably quit Firefox, I killed all the process of Excel running, or just rebooted.

  I uninstalled the Flash plugins and installed the latest version.
  If the problem occurs again, I will try it in safe mode.

  Thanks for your help so far!

• Double-click to open a Word or Excel file crashes just for centuries before opening it later.

  Recently, by double clicking on a file name to open a Word or Excel file, my PC crashes just for centuries before opening it later. Text files, PDF, jpg files and other open immediately, no problem. I have not changed the Word/Excel software recently and the extensions.doc/.xls file are correctly associated with programs. Why don't double-click work properly?

  Open Word/Excel and then use the file - dialog box open to open a file.

  Which causes the same delay?

• When open my photo album file and clicking on a photo to see the excel program opens the image viewer.

  I open an email with pictures.  When I click on the photo attached to the view, the excel program opens and not the image viewer.

  One of photo accessories save somewhere you can find it (for example, your desktop computer).
  Right-click on the file that you saved and select open with, then select "Choose program" (at the bottom of the context menu).

  If the program you want to use is listed as one of the "recommended programs", select it, click on the box to "Always use the selected program to open this kind of file" and click OK.

  If you want to use the Windows Picture and Fax Viewer to view photos (personally, I like free IrfanView better) AND it is NOT listed as a program "recommended" or under "Other programs", follow the instructions below:

  in Windows Explorer:

  • On the Tools menu, click folder... Options
  • Click the File Types tab.
  • Scroll down to the extension that you like, for example "JPG".
  • Press the restore button, if it exists.
  • Press the Advanced button.
  • Click the Open action.
  • Click on change...
  • In the Application used to perform action: enter C:\WINDOWS\system32\rundll32.exe C:\WINDOWS\System32\shimgvw.dll,ImageView_Fullscreen %1. "C:\WINDOWS" is the directory that contains your Windows installation.
  • Press OK

  You'll want to repeat for each extension (GIF, JPG, JPEG, etc.) for which you want to change the behavior.

• Whenever I open an Excel file, I get a pop for Windows Installer

  Original title: Windows Installer

  Every time I open an existing Excel file, Windows Installer opens first, there is a significant delay and opens the Excel file. What is the solution to get out of the process of opening Excel from Windows Installer files? I don't see Windows Setup in the control panel so I can't remove it.

  Thank you

  Hi Phil,

  Windows Installer tries to configure excel on your system.

  Click Start-> settings-> Control Panel-> Add/Remove Programs-> Microsoft office-> change-> add/remove component-> select excel, then click on run from my computer.

  Once its finished installation-> start excel from start-> programs-> excel (or in Microsoft office-> Excel).

  Let the full installation. Close excel and open your files.

  I hope this helps.
