  • EXCEL - Locking a Cell from User input whilst allowing a Linked combobox?

    - by Christopher Leach
    I have a Protected Worksheet which is a checklist with a series of checkpoints. Each row has Item and Description cells that are locked. Each row has several columns with its contents to be set by a ComboBox and a text input column. Both i have left unlocked. I have Locked the the Item and Description columns and left only the 'Select Unlocked Cells' checked via Sheet Protection. I have one ComboBox on the worksheet that moves around and adjusts its LinkedCell and its Content list using the worksheets SelectionChanged event. When the user selects a cell to bring up the drop down list, the user is able to type into the cell and the Drop Down Box disappears. What is the best way to keep the cell unlocked so it can be selectable(as 'Select Locked Cells" is unchecked) however stop the user from being able to type in the cell and to allow the cells contents to become modifiable only via the ComboBox?

  • Unable to download microsoft excel files from a IIS SSL site

    - by Jeffrey
    The web master at my corporation added SSL to the web site and now none of my users can download Microsoft word and xcel files the sites generates. According to Microsoft the following must be down. Web sites that want to allow this type of operation should remove the no-cache header or headers. Typical of MS they don't tell you what to do, how to do it, or what the best practice is. The web master says its a web config setting. But all i can finds is <configuration> <appSettings/> <connectionStrings/> <system.web> <httpRuntime sendCacheControlHeader="false"/> and I don't know if this is the best way to achieve the result. I would greatly appreciate some advice on this subject.

  • How to start with PowerPivot for Excel

    - by Marco Russo (SQLBI)
    Now that Office 2010 has been released, many people will start looking for resources to start learning PowerPivot.

  • Excel : les filtres avancés ou élaborés

    Outil puissant et finalement peu connu par les utilisateurs le filtre élaboré permet de filtrer des données avec plus de possibilités que le filtre simple dont on atteint très vite ses limites. En plus de filtrer les données sur place, il permet l'exportation de celles-ci vers une autre feuille ou un autre classeur. Son exploitation en VBA offre de belles perspectives de développement. J'espère que la lecture de ce tutoriel vous permettra de le découvrir ou d'en apprendre plus sur ses possibilités.

  • Solver Add-in not loading correctly

    - by Paul
    When I try to open solver from inside excel 2010, I get the error message: "Solver: An unexpected internal error occurred, or available memory was exhausted." The only way I have been able to get Solver to work is by going to "C:\Program Files\Microsoft Office\Office14\Library\SOLVER\", and just opening the file called "SOLVER.xlam". If I open excel through that file, the program works fine. Is there a way to solve this issue?
