I try using CreateCopy(), it seem in thrown me an exception when i run the program

It will display this output on the console:



enter image description here



I try debug on the exception occurs, on the call stack it will go to the new tab then display no symbol loaded



enter image description here



I hope someone can explain to me what file not be loaded and if the console can view raster map it is will throw an error or exception ?
Below is my code if someone want to copy and make reference it just i have issues on "Using CreateCopy()" part.



Thank you and best regards,

          You haven't set the variable pszDstFilename to anything meaningful. You allocated it, but it just contains random junk. You need to put a valid existing dataset into it for anything useful to happen in the call to GDALOpen(). The documentation states:




          Once the drivers are registered, the application should call the free standing GDALOpen() function to open a dataset, passing the name of the dataset and the access desired (GA_ReadOnly or GA_Update).
