* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* To upload a file we're simply sending a PUT with the content of the data.  For example:

* PUT https://myaccount.blob.core.windows.net/pictures/photo.jpg?sv=2015-02-21&st=2015-07-01T08%3a49Z&se=2015-07-02T08%3a49Z&  sr=c&sp=w&si=YWJjZGVmZw%3d%3d&sig=Rcp6gQRfV7WDlURdVTqCa%2bqEArnfJxDgE%2bKH3TCChIs%3d HTTP/1.1  
* Host: myaccount.blob.core.windows.net  
*   
* Content-Length: 12  
*   
* Hello World.  

* Upload a string to a helloWorld.txt file in the "mycontainer" container, in the "chilkat" account.
lcUrl = "https://chilkat.blob.core.windows.net/mycontainer/helloWorld.txt?sv=2021-06-08&ss=bfqt&srt=sco&sp=rwdlacupiyx&se=2023-02-12T21:30:53Z&st=2023-02-12T13:30:53Z&spr=https&sig=HB8CoZiD7EJD1rQNIVnLl%2Bq7kyLcOCnSXR14TadBv6s%3D"

loHttp = CreateObject('Chilkat.Http')

loHttp.SetRequestHeader("x-ms-blob-type","BlockBlob")

loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpStr("PUT",lcUrl,"Hello World.","utf-8","text/plain",loResp)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loResp
    CANCEL
ENDIF
