Creating .Excel File from a DatagridVIew

In order to fetch all the data from the grid view and create a .xls file of the data, use the following code .

private void CreateXLS()
{
DataTable dt = (DataTable)dgSearch .DataSource;
dt.WriteXml(@"C:\ABC.xls",System.Data.XmlWriteMode.IgnoreSchema);
dt.Dispose();
}


In case you get an error while converting the dgsearch.datasource to Datatable, convert the dgsearch.datasource to dataview and by using the property of dataview ie "Totable" convert it to datatable

Powershell: Filling up an Existing Excel Sheet with data from SQL Server

Situation: The client required to have data from their SQL Server 2012 Database filled in to an existing Excel Sheet. This sheet had a table with around 40 columns of which 12 where to be filled by us and rest from different departments. I tried different solution for that since the requirements were not initially clear. Forexample OPENROWSET was tried. In this regards this link really helpful. Although this requires few configuration to be made on the server or to install e.g. ACE.OLEDB driver on server which was not possible in our case. So we decided to write a Powershell script and access SQL Now about the script: Take the file TestExcel.xlsx from C:\Temp folder Create its copy with the current date appended to its name.  Start reading the Excel file from Sheet "Specified Sheet Name" From Columns 1, it will take the name of the system.  Based on the name fill the excel sheet by executing the queries, here are the columns that are going to ...

Per-user throttling in SharePoint Online: a Recipe for getting blocked in SharePoint Online and way to Avoid it

Image
Suppose you have a CSOM or REST API based code that connects with your SharePoint online Site.  This code tends to update several fields including metadata of a number of files in a document library in complex manner.  Or  Try, for instance, creating site collection in Pnp Powershell using "New-SPOSite" serveral times.  Or  Someone decides to Load test SharePoint Online site.  These are some of the use cases as well which you can can find on Miscrosoft documentation given in the rederence below.  Now you will notice, if you run into aforementioned situation, at certain point that SharePoint Online will return HTTP status code 429 i.e. Too many requests or 503 i.e. Server Too Busy (an HTTP response status 503 on Windows server means Service Unavailable.) and requests will result in failure. Furthermore, if one continues with one's transgressions i.e. keeps on running the script, as warned by Microsoft, the script will eventually exceed it...

SPFx: Develop using SharePoint Framework without Installing all the dependecies.

Image
SharePoint Framework (SPFx) has been around for more than 5 years now with being Generally available since Feb 2017.  In the recent times, its been possible to develop webparts for SharePoint on-prem as well using SPFx and with that it is getting harder to maintain multiple versions of required toolchains. e.g. Node. For M365 you can use the latest version of SPFx but probably you know, if you aim to develop webparts for the SharePoint Server 2016 platform, for instance, you need to use the SharePoint Framework v1.1.0 due to the server-side version dependencies. So yet another challenge is using the correct version of the SPFx and Nodejs for the particular project . Although I personally used to like Node Version Manager which lets you manage multiple installations of node.js on a Windows computer but still one needs to isolate SharePoint Framework dependencies if you are targeting multiple platform from on PC. 2nd Problematic scenario begins when you start developing SPFx extensi...
