I know this sounds backwards, but I have to convert this from C# to Classic ASP. I don't know any VBScript so I need help.
In my C# code, it is reading appkeys in the config file, parsing them, and using loops to perform a process. I don't know how to do dictionaries and I/O stuff in VBScript. Can someone please help with this?
These are the keys which I guess I would have to store as constant variables in the .asp file:
<add key="Output.Size" value="550" />
<add key="Output.Ext" value=".jpg" />
<add key="Output.Folder" value="thumbs" />
<add key="Suffix.LG" value="750" />
<add key="Suffix.TN" value="250" />
<add key="Suffix.TNL" value="175" />
<add key="Suffix.TNR" value="75" />
<add key="Supported" value=".jpeg,.jpg,.gif,.bmp,.tiff,.png" />
This is the C# code:
Generate generate = new Generate();
generate.Process(source, destination); //inputs will be relative URL paths
public class Generate
{
private const string OUTPUT_SIZE_KEY = "Output.Size";
private const string OUTPUT_EXT_KEY = "Output.Ext";
private const string SUFFIX_KEY = "Suffix.";
private const string SUPPORTED_KEY = "Supported";
private string[] supportedExt = null;
public Generate()
{
//GET ALL SUPPORTED FORMAT TYPES TO PREVENT PROCESSING ON UNSUPPORTED FILES
supportedExt = ConfigurationManager.AppSettings[SUPPORTED_KEY].ToLower().Split(',');
}
public void Process(string sourceDir, string destDir)
{
int thumbSize = Int32.Parse(ConfigurationManager.AppSettings[OUTPUT_SIZE_KEY]);
string thumbExt = ConfigurationManager.AppSettings[OUTPUT_EXT_KEY];
//COLLECT VALUES FOR RESIZING
Dictionary<string, int> resizeValues = new Dictionary<string, int>();
foreach (string item in ConfigurationManager.AppSettings.AllKeys)
{
if (item.StartsWith(SUFFIX_KEY))
{
resizeValues.Add(item.Substring(SUFFIX_KEY.Length), Int32.Parse(ConfigurationManager.AppSettings[item]));
}
}
//BEGIN GENERATING THUMBS
foreach (string item in Directory.GetFiles(sourceDir))
{
//VALIDATE IF FILE TYPE SUPPORTED
if (!supportedExt.Contains(Path.GetExtension(item.ToLower())))
continue;
string fileName = Path.GetFileNameWithoutExtension(item);
string outputFile = Path.Combine(destDir, fileName + thumbExt);
//RESIZE TO THUMB
Resize(item, outputFile, thumbSize); //DO NOT HAVE TO CONVERT "RESIZE"
//RESIZE TO DIFFERENT THUMBS
foreach (KeyValuePair<string, int> output in resizeValues)
{
string thumbSeq = Path.Combine(destDir, fileName + output.Key + thumbExt);
Resize(item, thumbSeq, output.Value); //DO NOT HAVE TO CONVERT "RESIZE"
}
}
}
UPDATE: As suggested below, I converted to a VB for easier translation. It seems I have to rethink things as well. This is where I am but am getting an error:

This is the error I am getting:
