Is it possible to convert PPP file to .ppt without using the interp or spire because I think it Would there be something like changing a binary file to open the Xml format?

Public Zero Convert PPTTOPPTX (MemoryStreamPTT FileInput, MemoryStreamPPTPFileOutput) {

.....

}

Thanks in advance.

If you want to program this, then you should be interop or some third party library < P> If you can use the interop, you will get office loyalty, no other third party library is just a great effort, unless it uses the interop under the hood, whatever they do. Make sure you check that the library needs to be set up in the office.

There is nothing here that is created directly in the Net Workfair, if you are asking this question will not support Microsoft's OOxML SDK conversion

Only Microsoft knows which PPT conversion is PowerPoint Automation Services , but it requires access to a SharePoint server

This is a simple problem that you understand and the PPT binary file To be able to read is not to solve

and then translate all into the OOXML file format

Considering thousands of features supporting all files, the differences in file formats, features which are not well documented, and the documents that are incorrectly

What are you trying to solve Are you? Once conversion, a batch conversion, as required? Maybe we can provide some more suggestions with more details.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
