I have an application that needs to have Dot Net 2 SP 2 installed because it detects it's not , I downloaded it from MS. When I try to run it nothing happens, I tried diff compatibility modes, nohting in event log. No AV loaded

any ideas how to install it on Server 2012 R2

I have recently purchased a backup UPS and it comes with software that can be loaded on a computer (that is connected to the UPS) so that the computer can communicate with the UPS and safely shut down.  

The software requires .NET 3.5, but vanilla Windows Server 2012 doesn't have it.  What roles/components need I install?  I tried adding the Application Server --> .NET Framework 4.5 but the software installation is still saying .NET Framework still missing.  Am I forgetting something?  

There are tons of other roles beneath Application Server, do I need to install more?

Thank you

How can I configure the IIS 8.5 in my Windows Server 2012 R2 to redirect:

www.domain.com/app to point to the www.domain.com (under the same webserver) ?

Because at the moment:
www.domain.com/app --> is showing IIS 404
www.domain.com --> works fine as my primary website.

I want to view which folders on a netapp a security group is granted NTFS permssions.

How can this be accomplished? Powershell?

Any other alternative ?
I am experiencing very slow printing of labels (including barcodes) in vb.net to a thermal printer (TOSHIBA TEC B-SA4T) especially when I have to create several tags (each slightly different) in one batch.  

Can anyone help me out and maybe suggest a better alternative?  I have read a few articles which stipulate that vb.net is slower than vb6 when it comes to printing (I don’t want to downgrade to vb6).  

Current benchmark with VB 6 the object prints after 1 second, with a vb.net command (printDocument) prints after 3 seconds.

I have been having some weird behavior with one of our legacy web applications.

from time to time our connection between the web app and sql goes stale. we have daily app pool recycles early in the AM, however random app pools on random nodes do not reattach to sql and go into a "stale"/"Zombie" state at the time of recycle (prob 95% of the time it appears to be around recycle)

the usual fix is to cycle the pool. IIS Reset will work however that will impact other sites on the webserver

I used a script via schedule tasks to verify that new PIDs are being generated and they are.

according to the DBA, the box is done with its nightly chores at the time of our recycle.

none of our .net4 app pools exhibit this behavior


I have 2 List<string>: list_A and list_B.
it has 3 items inside each.

I got the values from api call and they are:
Iist_A[0] : "Hello"
list_A[1]: "I am <br><br> Isabell"
list_A[2]: "Sincerely, <br><br>Isabell"

I retrieved the values from DB and stored those to list_B.
I added and deleted items on list_B since I had to manipulate the data and string.
So when I finally added items, the previously stored items were overwritten by the new ones.
However, at the end, this is what I got for list_B.
Iist_B[0] : "Hello"
list_B[1]: "I am <br><br> Isabell"
list_B[2]: "Sincerely, <br><br>Isabell"

When I checked the values using Locals window in Visual Studio, I verified that all the values were matched. I even used 'Text Visualizer', but the results were exactly matched.
However I am getting "false" on the following statement.

How could this happen and how to fix this issue?
Is there a way to use .net to open a command prompt on a remote PC and run an exe?  Then I would also like to parse the response text this exe produces.  I can get this to run using psexec from my local command prompt, but I can't get it to run using .net.
We have developed a web app hosted on Azure, which copies the records in a SQL View to a MySQL Db for a Wordpress Website.
All is working fine, but it is a scientific website and some of the records contain greek letters. These characters are not being carried over correctly, and display as question marks on the website.

On investigation, I have read that others had success with a similar issue by forcing conversion of the field containing the greek characters to UTF-8 with a SQL command on the My SQL destination Db, others found converting it to Latin1 resolved their issue. However, I had success with neither of these.  I also discovered that the greek characters appear to be converted to question marks before being sent to the MYSQL: When outputting the field values with console.writeline() in the vb code, the values expressed display '?'s instead of greek characters before they are exported to the MySQL Db.

So I'm wondering if there is any known process which I can put those fields through to ensure the greek characters are kept and remain untranslated to '?'s in the export functionality.

Incase it helps, following is a sample of the code used to write the values from the SQL view to the MySQL table:

        Dim DBAAW As New MasterDBEntities '(this is the SQL Db)
        'first find the Antibody Record by its HCConstructNumber
        Dim WARecord = (From wq In DBAAW.WP_Whole_Antibodies_on_Sale

Dear Expert!
I have some Excel workbooks consisting of data and Excel-functions that also relies on a substantial chunk of (identical) VBA to produce the results, and now I would like to move this into the iOS world. What  thought was the obvious solution, using Excel for iPad, doesn't work since it doesn't handle any VBA and doesn't have any macro language (I also find it rather awkward to work in...)

So my question is if anyone has used a generic app for anything like this (handling Excel functions, workbooks and possibly has a macro/script language), since I prefer not to do a full App-development. Or if you have creative ideas how to solve this?

Since the question is for high-level ideas, there is no point of adding any example.

Of course I have no problem for any biased answers from developers working at the company who has an existing app for this, but I am not looking for proposals on development of an app ;-)
Good morning all,

I am looking for a software  or web app or single page app that will allow me to create, manage, publish, share my items catalog.

The list of items available in our catalog can be used to create blocks. For instance, we know what are the services/goods required to do a basic "Site Preparation for Construction" when we pick "Site Preparation" all the tasks/services/goods required show up then we can amend the quantities of each items according to which site preparation we are doing.

Meaning that I need to have the flexibility of associating each item to one or more types of work and for each project I should be able to pick the various types of works required and amend quantities accordingly.

I believe I might end-up having to develop it but however, if I don't have to I don't mind purchasing the licenses.

Please refer me to some excellent tools.

Thanks and Kind Regards,

I have published an App Service to MS Azure (Europe North). My service needs to access an application on my local network via net.tcp.
I therefore need to change my local firewall configuration to allow access from Azure.
The problem that I have is that I can't work out what Azure IP address ranges to use in the firewall.

I have downloaded the latest Azure IP range document from Microsoft but the range of IP addresses for Europe North is huge.
So a couple of questions.
1. Do I need to enter all these IP addresses into my firewall, just in case I am using one of them?
2. Is there a way I can find out the IP address of the server I am running on. (The app is a C# App)?

Thanks for your help
