We have an ASP.NET forum, and the answer has nothing to do with C#, as it happens. You just put an image tag on your page and point it to the URL of the file on your server.

If you meant something more complex, please ask more clearly in the correct forum.

What do you mean by page, is this an ASP.NET question ? What have you tried ? Is this for a class, or for your paid job ?

Can i use tab button in date time picker? Purpose is- while entering date in form Date time picker is used. First I enter DD than to enter MM i'm supposed to use arrow key to move to MM. For that i want to use tab key.

How to use?

If the control does not support it ( which seems odd ), then you'd have to either figure out how to hack the control to have a tab order, or write your own.

Why would you ask a question from someone else who doesn't know how to use the control ? A DateTime does NOT have a format, it's up to you to format it.

I'm doing a program like MS Paint in C# (windows forms) and one of the requirements is to have a tool that blurs or smudges the image you are working on, be it an imported picture or text, lines, whatever we painted before. Can someone please help??

You should read my image processing articles. The blur filters in there can be applied as a tool, with a bit of work. Just click on my name, then click to view my list of articles.

Is it possible to access 32bit dll from 64 bit dll

I have two c# projects, one is 64 bit and another is 32 bit.

Is it possible to access 32bit dll from 64 bit dll?

You cannot load both 32bit and 64bit code into the same process.

I would strongly suggest you avoid mixing the two in one application.

The only way you could use both 32bit and 64bit code is to create one process for each and use some kind of inter-process communication (.NET remoting or similar).

Thanks Daniel, the reason is our Application is 64bit and I need to introduce an ActiveX 32bit control into our program.
Is it possible to create an idividual 32bit project for this ActiveX control, then let 64bit host applicaton to launch it?

The only way you can get one to talk to the other is if the 64-bit code is in a one process (i.e.: an .EXE) and the 32-bit code is in a completely seperate process, another .EXE. There is no way to get a 32-bit ActiveX control to work in a 64-bit app.

If you install 64-bit Vista or Windows 7, there are two versions of Internet Explorer installed, one 32-bit and the other 64. Why do you think that is?

That won't work, the first application won't start if the second one isn't in the proper place (and the second application will just update itself to where it was before).

Custom 404 Error Handler

Joe Kohler6-Nov-09 11:19

6-Nov-09 11:19

I am trying to trap specific request for pages on my website. The custom errors defined in web config works fine for URLS with a page reference such as:
http://www.mydomain.com/123/i_dont_exist.aspx

This will redirect to my error page.

The problem is this:
http://www.mydomain.com/123

The directory 123 does not exist but the ie 404 displays, not my custom error page.

Any thoughts would be greatly appreciated.

C# File/DirectoryPermissions "Apply Onto" Advanced

I am looking for a way using C# to retrieve the "Apply Onto" value viewed when looking at the advanced properties for a directory.

<br />
             ...<br />
              // get security for directory<br />
              AuthorizationRuleCollection arc =  security.GetAccessRules(true, true, SECURITY_IDENTIFIER_TYPE);<br />
              foreach (FileSystemAccessRule fsar in arc) {<br />
                  String type = fsar.AccessControlType.ToString();<br />
                  ...<br />
              }<br />

I am trying to progromatically figure out which "Permissions Group" ( Full Control, Modify, Read and Execute a file and or directory is assigned.
List folder contents, Read, Write) is assigned.. I don't see anything stored on the FileSystemAccessRule to give me the "Apply Onto" field. Is there another object I have to use?

Read and Execute AND List folder contents have the same exact rights, but differ by the "Apply Onto" field.

List folder contents the Assigned onto field is : "This folder, subfolder and files"
Read and Execute the Assigned onto field is : "This folder and subfolders"

Is there another way to figure out this problem?

Any help would be appreciated.

Thanks.
