Link to Excel on Jump Drive
I have a Word 2013 file with links to various ranges on an Excel file. I had them all on my computer, but now they are on a Jump Drive. Unfortunately with them now on a jump drive, the drive letter can change. Both files are in the same directory. Is there any way to edit the links without the full path?
That is, I want to go from
F:SecretaryMinutesTables.xlsx
to
Tables.xlsx

Utilizing Azure Storage and Runbooks for scheduled automated backups of Azure SQL Databases
In this article, we are going to provide detailed steps to create a scheduled Azure SQL Database backup to storage account using automation. This is a useful technique for maintaining regular backups of your database and storing them in a secure and accessible location. You will get an actual backup of Azure SQL Database stored in a storage account in .bacpac format, which you can restore or migrate as needed. The automation process involves creating an automation account that triggers a PowerShell script through a runbook to run the backup command and save the output to a blob container.
Prerequisites
Azure Storage account: The storage account is needed to host the database backups. You are required to set up a container within this account to store the backups.
Azure SQL Database and Server: This is the database you will back up, along with its hosting server. Ensure that you grant Azure services permission to access the server where this database is hosted by selecting “Allow Azure services and resources to access this server” within the networking section, as illustrated in the following documentation: Network Access Controls – Azure SQL Database & Azure Synapse Analytics | Microsoft Learn
Azure Automation account and PowerShell Workflow runbook: These components are utilized to set up automatic backups and their scheduling. make sure to using a PowerShell version 7.2 or above when creating the runbook. To learn more about setting up a PowerShell Workflow runbook in Azure Automation, please check the following documentation: Tutorial – Create a PowerShell Workflow runbook in Azure Automation | Microsoft Learn
Setup
Once all the necessary prerequisites are in place, you should navigate to the runbook and click on “Edit.” Then choose the “Edit in portal” option as illustrated below:
The editor interface for the runbook will launch, displaying the runbook you created earlier. Enter the following code into the editor area:
# Connect to Azure with system-assigned managed identity
Connect-AzAccount -Identity
# set and store context
$AzureContext = Set-AzContext –SubscriptionId “*****”
# Resource group name
$resourceGroup = “*****”
# Storage account name that will have the backups
$storageAccountName = “*****”
# Storage account access key that will have the backups
$storageKey = “*****”
# Container name that will have the backups
$containerName = “*****”
# storage blob uri with the datetime
$storageUri = “https:// *****.blob.core.windows.net/*****/db-$(Get-Date -UFormat “%Y-%m-%d_%H-%m-%S”).bacpac”
#Storage access key type
$storageKeyType = “StorageAccessKey”
#SQL server name
$server_name =”*****”
#Database name to be exported
$SQL_db = “*****”
#SQL Auth Username
$SQL_username = “*****”
#SQL Auth Password
$SQL_secure_secret = ConvertTo-SecureString -String “*****” -AsPlainText -Force
# Run the Export job with the required parameters
New-AzSqlDatabaseExport -ResourceGroupName $resourceGroup -ServerName $server_name -DatabaseName $SQL_db -StorageKeyType $storageKeyType -StorageKey $storageKey -StorageUri $storageUri -AdministratorLogin $SQL_username -AdministratorLoginPassword $SQL_secure_secret
Ensure you fill in all the ***** with the appropriate values for the step you’ve designed, then press the “Save” button located at the top left corner. The parameters given relate to details on subscription and resource group, as well as information on the SQL database, server, and storage account. You’ll find explanations for each parameter in the code snippet provided above.
Select the test button on the toolbar, which will display the test pane allowing you to test the script prior to scheduling. Hit the start button and monitor the requests; if the run is successful, you should observe an outcome like this:
You can monitor the progress of backups and access the export history through the SQL server in the “Import/Export history” section, as illustrated below:
After the backup finishes, it will appear in the storage account with the datetime suffix provided by the script:
After verifying the script operates correctly, you may go ahead with publishing the runbook and link it to a schedule based on your requirements according to the following documentation:
Manage schedules in Azure Automation | Microsoft Learn
You can initiate the automation by pressing the start button, schedule it to run automatically, or set a webhook to trigger the process. Remember that you can only run one export job at a time. If you attempt to run two jobs simultaneously, one will not succeed and you’ll receive an error message stating that another export job is already in progress.
Recommendations
Establishing a routine backup schedule for a large database over an undefined timeframe can lead to substantial storage consumption and potentially significant costs. It’s important to regularly monitor your storage account and remove unnecessary backups, or consider relocating them to more cost-effective storage tiers, such as cold or archive.
It might be beneficial to consider implementing a storage lifecycle management policy to manage data within the storage account and decrease the costs associated with storing database backups. Lifecycle management can help you in creating an automated schedule to delete blobs or transition blobs to a different tier that is less expensive like cold or archive tiers based on creation date. For additional details on storage lifecycle management and instructions for configuration, please consult the provided documentation:
Configure a lifecycle management policy – Azure Blob Storage | Microsoft Learn
If you have soft delete enabled on the storage account, make sure that the retention period is set appropriately to avoid incurring additional charges for retaining soft-deleted data over an extended period.

Compatibilité Excel2010 2021
Bonjour, j’adresse ce message aux experts d’Excel, après avoir obtenu le lien de ce site d’un conseillerMicrosoft en ligne, seuls vraiment susceptibles de pouvoir m’aider.
Le fichier Excel joint sur PC est autonome. Il permet, dans une grilleA1 à AK27 ; d’afficher des nombres croissants de 1 à 999 au maximum dans un emplacement aléatoire de la grille. A la fin, les 999 cellules de la grille sont renseignées et mémorisées dans le second onglet. Le calcul itératif est actif. Pour ce faire, retirer le « x » Reset grill on et mettre un « x » dans Start. Le remplissage commence.
Le problème précis est le suivant :
Développé sur Excel 2010, il fonctionne très bien. C’est è dire que pendant que les itérations s’écoulent, l’affichage des nombres , dans la grille est visible. A la fin d’un cycle d’itérations, un re calcul d’Excel, le fait poursuivre.
Depuis peu, sur un autre PC, ce logiciel est lancé par Excel 2021. Et là, petit problème dérangeant.
En effet, les mêmes manipulations ne provoquent l’affichage des nombres , dans la grille, qu’à la fin du cycle d’itérations en cours, seulement à la fin, et la progression d’affichage n’est pas visible, tant que le cycle n’est pas terminé, ce qui est dérangeant, surtout en configurant un nombre important d’itérations.
Malgré des comparaisons des 2 config d’Excel et multiples essais, en ce sens, je ne sais pas ce qu’il faut modifier, pour supprimer ce problème.
Les lieux d’action sont les suivants : BG35/36/37 pour créer les emplacements aléatoires et la colonne BL pour les placer dans l’ordre de création.
Il y a probablement une configuration d’Excel 2021 qui doit permettre de visualiser cette progression, je l’espère.
Les onglets sont protégés sans mot de passe.
Merci d’avance de votre précieuse aide.

Is it possible to have a string constant (output datatype: string) generated in UTF-8?
"Simulink strings support 256 characters of the ISO/IEC 8859-1 character set" according to Simulink Strings in the Help Center.
I’ve created a "string constant" block called "String ãºç" in a simulink model where I’ve inserted the value "exampleàñçº".
The block’s name is exported correctly in UTF-8 ("String ãºç"), but what I get in the exported file for the value is "example340361347272" (octal values for extended characters in ISO/IEC 8859-1).
I was wondering if there was a way to export the string value in UTF-8."Simulink strings support 256 characters of the ISO/IEC 8859-1 character set" according to Simulink Strings in the Help Center.
