How can I filter by file type in an IExplorerBrowser in Windows 7 Libraries? -

-

I created an example of IExplorerBrowser in my code to create a custom I / O view in one of my dialogues. The host class has implemented the ISISprovider and ICMML Browser Interface. I use the IExplorerBrowser :: BrowseToIDList method to fill the view.

I would like to filter the displayed file type (i.e. only PNG files) if I call BrowseToIDList with FOLDERID_Pictures (ie "My Pictures"), then I will call ICommDlgBrowser: : Include Object Method or IFolderFilter :: ShouldShow can restrict the files I allow to display. However, if I browse the Picture Library on Windows 7 ( FOLDERID_Pictures library ), then the ICommDlgBrowser :: Not included object and IFolderFilter :: ShouldShow is sometimes called.

Is there some limit for filtering files in libraries on Win7 which I am unaware of? Maybe I can not find an interface or maybe I have specified the wrong flag somewhere.

Any ideas will be highly appreciated.

I have had the opportunity to do further research, including some questions for some developers, unfortunately, This filtering query does not work with backed scenes (i.e. libraries).

An alternative to my perspective has been added, with app add control (via IFileDialogCustomize). / P>

In my specific case, I am unable to use a general item dialog, but I thought it was appropriate to post this information here for future reference. It is possible.

If I find a way to filter an IExplorerBrowser control in the future, then I will also post back here.

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket.

It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
