Hi,
We are using Remobjects SDK with Delphi 7 in our Client/Server software. And Interbase as back end.
We are getting errors while passing a 100mb .avi media file from Client to Server.
Actually what we are doing is…
- Created a clientdataset with a Blob type field.
- Then we are creating a Tmemorystream variable and loading .avi file in that
- Then we are converting the memorystream to string
- Then we are loading the string to clientdataset BLOB field
- Then we are passing the clientdataset data to server by using remobjects sdk
- And in server side we get error.
Some of callstack…
