Passing data between two applications via third application - asp.net

I have an asp.net application containing two pages Add/Edit Customer and Customer List(View).
There is one more host ASP.NET application that uses ajax tab container/accordian to host above two pages in iframes. So as shown below TAB1 contains Edit Customer Page in iframe 1 and TAB2 contains View Customers Page(only one can be active at a time). If I have to move from TAB2 to TAB1 (e.g. user clicks on edit link in customer list), then I have to refresh host application by passing name of tab in querystring(This part is handled by the Host App and is the only available way to switch TAB).
What is the best way to pass data from TAB2 to TAB1 other than query string? I don't want to change host app url by appending querystring as it will be hard to reset the querystring without reloading. My application is in webfarm and has IP session affinity based load balancer. We use in proc session currently but it fails occasionally which is obvious. Are there any proven ways to handle this scenario in webfarm if I remove out-proc sessions out of the question?
----------------------------------------------------------------
ASP.NET MAIN APP CONTENT
VirDir-B
[parent]
**________________________________________________________________**
TAB1 | TAB2
[iframe1] | [iframe2]
{ Edit Cust | { View Cust
VirDir-A } | VirDir A }
|
UPDATE :
Well, I solved this problem using javascript by directly setting source of iframe1 with querystring parameter as all my VDs are in same domain.
PSEUDO CODE:
On View Page:
var tabContainer=$(parent.document).find('#TABCONTAINERID').control;
var iframe=$(parent.document).find('#TABCONTAINERID').children('#iframe1');
iframe.src="editCust.aspx?id=123"
tabContainer.set_activeTabIndex(0);
But I'm curious to know how this could have been handled if I had no control over parent application(may be in different domain).

At least two methods I can think of could be used:
Passing the data to a cookie, then reading it on the other tab
Sending the data to the ASP.NET host app using ajax and downloading it on the other tab

Two wordpress database with same users

I want to have the same WordPress users in two different databases
For example, if a user registers on SiteA, then he can login to SiteB. And reverse.
Also i want create same cookie for both after login.
mywebsite.com/ (SiteA_DB)
mywebsite.com/blog/ (SiteB_DB)
I've never done this before and maybe Wordpress has hooks to archive this, but I prefer using mysql for such a trick.
You could try ..
.. using 'federated storage' ( https://stackoverflow.com/a/24532395/10362812 )This is my favorite, because you don't even have to share a database or even the mysql serverThe downside is, that it doesn't work with db cache and uses an additional connection.
.. creating a 'view' ( https://stackoverflow.com/a/1890165/10362812 )This should be possible when using the database-name in the query itself and it would be the simplest solution if it works. Downside: The 2 tables have to share the same mysql-server and have to be assigned to the same user as far as I know.
-- **Backup your database before trying!** --
DROP TABLE `second_database`.`wp_users`;
DROP TABLE `second_database`.`wp_usermeta`;
CREATE VIEW `second_database`.`wp_users` AS SELECT * FROM `first_database`.`wp_users`;
CREATE VIEW `second_database`.`wp_usermeta` AS SELECT * FROM `first_database`.`wp_usermeta`;
This should work, according to: Creating view across different databases
.. creating a 'shadow copy' ( https://stackoverflow.com/a/1890166/10362812 )Works with caching and is a standalone tableDownsides as 2. solution + a bit of setup and I think it might be the worst option in performance
This were answers to this question: How do I create a table alias in MySQL
I merged them together for you and made them fit your use-case.
Please also notice, that solution 1 and 2 will replace your current user-tables auf "second_database" because you write directly into "first_database" when querying the fed. storage or the view. This can lead to problems with user-role plugins. You should take care of syncing the plugin-options too, if you should use one of them and in case it uses different tables or 'wp_options' values.
Let me know if this works, I have to do a similar task next week. While researching I found the linked answers.
EDIT: I was missing the point of "cookie-sharing" in my answer. Your example shows a blog on the same domain - you should be able to change the way wordpress sets its cookies to be domain-wide. What I did once for 2 different domains was, that I hooked into the backend (is_admin) and added a javascript which did a post-request to siteB, receiving a token which is stored but marked as 'invalid' on siteB. This token then was passed back to my plugin on siteA which checked if the user is logged_in and (in my case) have adminrights (current_user_can()) and if so, it was sending this token back to sideB which was marking this token as valid to login. (Make sure only sideA can tell sideB to make this token valid!) Once a user is seen with this token in a cookie on siteB, the user is logged-in automatically in the background. Also I made this bidirectional. I am sorry, that I can't share the code for you. I don't have access to it anymore.
Greetings, Eric!

Google App maker multiple files drive upload

We are going to use drive picker as attachement field, so whenever an user uploads a file or multiples files to drive we have to get the links of the files and show it to the user in the form.
Here is a code sample with following assumptions:
you have Master and Attachment models with One-to-Many relation
datasource of the current page is set to record from the Master model
datasource is in Auto Save mode
// onDocumentSelect Drive Picker's event handler
var create = widget.root.datasource.relations.Attachments.modes.create;
result.docs.forEach(function(doc) {
create.item.Url = doc.url;
create.createItem();
});
This code will make N requests to the server, where N is number of attachments. You can use google.script.run to make a single call and handle creating new attachment records and relations on server, but then you'll need manually reload relation to show changes to user.

presence control in asp.net web applications

I've managed to implement the Name.NameCtrl.1 active x used in sharepoint in my own custom built apps for presence. All is working fine and I'm updating presence status correctly based on a users status on Office Comunication Server. However I'm not getting any other details on the user propulated in the presence control like it does in SharePoint. All I get is the sip address in the email field (rather than the real default email address in AD) and a link to schedule a meeting.
Can anyone tell me how to get the control to populate with details from AD (dept, email, phone etc) like it does in sharepoint?? Also I don't get an organization tab in the control like sharepoint.
Any ideas?
Thanks,
Keeney
NameCtrl gets the majority of its data from the running instance of Communicator (or Lync, if you're using that) on the client machine. No data is directly pulled back from SharePoint. To have NameCtrl work properly on your web pages, you need to make sure that:
Communicator (or Lync) is running on the client, and signed in
The web page you are calling NameCtrl from is in the Intranet or Trusted Sites zone in your browser
The recommended pattern is to call PresenceEnabled on the NameCtrl object before calling any other methods - if this returns false, then one (or both) of the above prereqs is false. The code below generally works for me
<script>
var sipUri = "your.contact#your.domain.com";
var nameCtrl = new ActiveXObject('Name.NameCtrl.1');
if (nameCtrl.PresenceEnabled)
{
nameCtrl.OnStatusChange = onStatusChange;
nameCtrl.GetStatus(sipUri, "1");
}
function onStatusChange(name, status, id)
{
// This function is fired when the contacts presence status changes.
// In a real world solution, you would want to update an image to reflect the users presence
alert(name + ", " + status + ", " + id);
}
function ShowOOUI()
{
nameCtrl.ShowOOUI(sipUri, 0, 15, 15);
}
function HideOOUI()
{
nameCtrl.HideOOUI();
}
</script>
<span onmouseover="ShowOOUI()" onmouseout="HideOOUI()" style="border-style:solid">Your Contact</span>
In case you haven't already seen it, there is a good(ish) NameCtrl reference here
I think in SharePoint, the control is populated with data that exists in the user profile service. If you want this in a non-sharepoint ASP.NET web app, then you'd have to build a repository of user profile details from AD (and cache it!) which your control will look to to display that information.

Exchange Server Webdav: How to retrieve the unique id of new items created

I am creating the appointments using WebDav in Exchange server 2003 and it is working perfectly fine. I however want to get an handle for the newly created items for future user like setting custom property/deleting etc.
How to get back a unique ID or something for the newly create the appointment? Does the PROPPATCH return any value??
Thanks
Shreedhar
When you create new item server returns MultiStatus. Inside MultiStatus response is item's url. Keep this url for later use (to delete/update item).
http://msdn.microsoft.com/en-us/library/aa142976(v=exchg.65).aspx
There is also a library with clean design from Independentsoft which implements WebDAV protocol for Exchange. It also returns item's url when you create new item.

Programicatlly visit (all) ASP.Net page(s) in a website?

In the Security model for out ASP.Net website (.Net 3.5) we store the page name:
page.GetType().Name
as the primary key in a database table to be able to lookup if a user has access to a certain page. The first time a page is visited this record is created automatically in the database.
We have exported these database statements to insert scripts, but each time a new page gets created we have to update the scripts, not a huge issue, but I would like to find an automated way to do this.
I created an attribute that I tagged a few pages with and then wrote a small process to get all the objects that have this attribute, through the reflection create an instance and insert the record using the same code to for page records mentioned above:
IEnumerable<Type> viewsecurityPages = Assembly.GetExecutingAssembly().GetTypes().Where(t => t.IsDefined(typeof(ViewSecurityAttribute),false));
foreach (Type t in viewsecurityPages)
{
object obj = Activator.CreateInstance(t, false);
//clip..(This code just checks if the record already exists in the DB)
if (feature == null)
{
Attribute attb = Attribute.GetCustomAttribute(t, typeof(ViewSecurityAttribute));
if (attb != null)
{
CreateSecurableFeatureForPage((Page)obj, uow, attb.ToString());
}
}
}
The issue is that page.GetType().Name when the page goes through the actual page cycle process is something like this:
search_accounts_aspx
but when I used the activator method above it returns:
Accounts
So the records don't match the in the security table. Is there anyway to programtically "visit" a webpage so that it goes through the actual page lifecycle and I would get back the correct value from the Name parameter?
Any help/reference will be greatly appreciated.
Interesting problem...
Of course there's a (too obvious?) way to programmatically visit the page... use System.Net.HttpWebRequest. Of course, that requires the URI and not just a handle to the object. This is a "how do we get there from here?" problem.
My suggestions would be to simply create another attribute (or use that same one) which stores the identifier you need. Then it will be the same either way you access it, right?
Alternatively... why not just use a 3rd party web spider/crawler to crawl your site and hit all the pages? There are several free options. Or am I missing something?
