How to open DOC/XLS files using UIWebView on iPhone 3.0?

Question

Hi,
I am using the following code to display doc/xlst files on UIWebView. It's surprised that I can get the content of the file but cannot show in WebView.
NSData *myData = [NSData dataWithContentsOfFile: fileDesPath];
NSString *ext = [m_openFiles.fileExtension lowercaseString];
NSString *mimeType;
if ([ext isEqualToString:@"doc"]) {
mimeType = @"application/msword";
}else if([ext isEqualToString:@"xls"]){
mimeType = @"application/vnd.ms-excel";
}else if([ext isEqualToString:@"wma"]){
mimeType = @"audio/x-ms-wma";
}else if([ext isEqualToString:@"jpg"] || [ext isEqualToString:@"jpeg"]){
mimeType = @"image/jpeg";
}else if([ext isEqualToString:@"tif"]||[ext isEqualToString:@"tiff"]){
mimeType = @"image/tiff";
}else if([ext isEqualToString:@"htm"]||[ext isEqualToString:@"html"]){
mimeType = @"text/html";
}else if([ext isEqualToString:@"mov"]){
mimeType = @"video/quicktime";
}else if([ext isEqualToString:@"mp4"]){
mimeType = @"video/mp4";
}else if([ext isEqualToString:@"txt"]){
mimeType = @"text/plain";
}else{
mimeType = [NSString stringWithFormat:@"application/%@", ext]; //pdf
NSLog(mimeType);
//Here, I can get the myData. The value is the content of the doc file.
if (myData) {
[self.myWebView loadData:myData MIMEType:mimeType textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:fileDesPath]];
After loadData, it cannot show anything in webview!
Can someone help me in this matter?
Thanks,

Hi Maurício -
For your future reference and for the information of everyone who comes across this post in the future:
We host all of our DataPlugins on our website at ni.com/dataplugins.  There are hundreds of file formats supported through the available DataPlugins, and there is also a link on that site where you can request a DataPlugin be written for file formats that aren't currently supported (such as custom *.CSV files).
