Can you post the code itself (not as an image)?

 

[khosrwb]

this is my code :

 

[Erel]

The zip file looks empty.

The zip file looks empty.

no. he is using filenames with special characters. maybe arabic or so (dunno)

 

[NJDude]

The ZIP file contains the source code, but, it's missing the "1.html" file, the code I posted before should work as long as the HTML EXISTS on the device.

 

[khosrwb]

excuse me
this code is here :
This error is displayed when I compile the code with (( F5 or Ctrl+3 ))
but when I use (( Ctrl+2 )) to compile this code there isn't problem

 

[NJDude]

Just to prove that the code I posted works, see the attached sample.

Note that if you want to use DirRootExternal, you have to copy the HTML to that location BEFORE you read it, the sample I attached just shows you how to read an HTML saved on the device and display it on a WebView.

hi NJDude
I run your sample code
but This error is displayed :
I do not know what this error means there

 

[NJDude]

Re-download the sample and try again.

 

[khosrwb]

thanks but
I will save the html files on the sdcard and then load html file from sdcard by app

 

[Mahares]

Since your file is in the sdcard, simply replace this line:

myHTML = File.ReadString(File.DirAssets, "1.html")

with this in NJDude's sample program:

myHTML = File.ReadString(File.DirRootExternal, "1.html")

 

[khosrwb]

thanks Mahares
thanks for all the help and attention
but I don't know why my app show this error

If you comment the Do While True line and the Loop line, your code will work. I think the reason you are getting the 'Unreachable' statement is because when you issue the following command: FD.FilePath = InitialFilePath, it initially sets the chosen file name to a blank string, so the condition is never True.
