export rsa key container

Posted By:      Posted Date: August 25, 2010    Points: 0   Category :ASP.Net

1) I want to create a rsa key in c# and export the container. I am having difficulty. I create container like this:

CspParameters cspParams = new CspParameters();            cspParams.KeyContainerName = "XML_ENC_RSA_KEY";CspParameters cspParams = new CspParameters();
cspParams.KeyContainerName = "XML_ENC_RSA_KEY";

The msdn example says I can export the container with this syntax:
aspnet_regiis -pa "XML_ENC_RSA_KEY" "NT AUTHORITY\NETWORK SERVICE". This does not work on my XP Host PC. I belive this is applicable for Windows 2003 Server.
So what is the correct syntax for exporting rsa key container from XP host?

2) To get aspnet_regiis.exe path I did something like this:

string winPath = Environment.GetEnvironmentVariable("windir");       
string fullPath = winPath + @"\Microsoft.NET\Framework\v2.0.50727" + @"\aspnet_regiis.exe";

But this path may be different for each host, based on the .NET verison installation.
Is there a way to get the aspnet_regiis.exe path from registry or a environment varaible?

3) Once I get the path to aspnet_regiis.exe I want to invokve it from c# like this.
Is this code correct?

Export Visio Database Table Names to Excel

If you use the Enterprise Architect edition of Microsoft Visio for data modeling regularly, then there is a good chance that at some point you've wanted to export just the table names into Excel.

Configuring Profile Image Export in SharePoint 2010

It's no secret that I am thrilled with the new social features of SharePoint 2010. I am most excited about the new Profile Picture handling. I strongly believe that the more we can show the faces of our colleagues to one another the more connected we will feel. Clearly Microsoft feels that way as witnessed by the many features that make use of the Profile Image like the Activity Feed and Colleagues list

Tab container rendered with visibility:hidden - This was reported over three years ago.



Here is (more) code that demonstrates the issue.  If the control in the host page is removed the tab control renders correctly.  Otherwise it is rendered with the visibility attrubute set to hidden as reported in the above link.  Is this broken or am I doing something wrong?

Re-positioning an HTML container with javascript onresize with a Master page.


I have an HTML <div> container that I float to the right of a gridview.  When the browser window is maximized, it looks fine.  When minimized, the gridview positions below the floating container and most of the data is pushed off the bottom of the browser - you have to scroll down to see it.

If I position the floating container above the gridview it looks fine in a minimized window, but looks real bad when maximized.

What I want to do is use a javascript: onresize event to re-position the floating container up or down depending on the window.inner.width AND do it with a Master/Content page structure AND do it for only the one page where needed.

I can capture the onresize event and display the window dimensions but haven't figured-out how to do it with a Content page that still uses the Master page.  I think I'm having a very "thick" week...

Cannot export from a Report in SharePoint integrated mode in a server hardend environment


We have installed Reporting Services 2008 integrated with MOSS with SQL Server 2008 on a 64 bit platform.

The environment has worked fine in test (but the servers are not hardend).

With the production environment, any attempt to export from a report into another format (eg excel, tiff etc) results in an unexpected error within SharePoint requiring closing the browser and reopening.

There are no details behind the error. We can also find no traces of the error within any of the logs (SharePoint, Reporting Services, Windows event log etc)

When the report is opened directly from Reporting Services (ie http://servername:8080/reportserver) the report exports fine. Similarly, if the report is opened directly from Report Builder 2, or through opening Report Builder 2 from SharePoint there is no issue. This issue only happens when the report is invoked directly through SharePoint.


We can only assume that this issue has something to do with server hardening/UAC as we have

ASP.NET Excel Export Issue



I am trying to export data from SP to a .xlsx sheet. Total no of rows is more  than 15000 with total of 13 columns.The data is generated with the help of SQL Server SP. Till this point it is working fine. However while exporting to excel I do not get any data , the excel  has blank content.

If I have records less than 12000 it generated the excel report with  relevant data. However as row increases the report is blank.

Also the excel is generated through the code but when I deploy to server and try to generate it generates a blank excel. 

 Please advice what needs to be done. I have tried multiple options but none works.

sql server 2008 import/export wizard... completely useless??



import/export wizard in 2000 had lots of options.

I could copy databases without a care in the world. Including constraints, stored proc., AND the data, etc.

Now, with v2008, the wizard is dumbed down too much. It's a "stupid" copy function that fails on the first constraint it meets.

"Copy database.." is not an option here: it needs sysadmin on both source and destination server.

Re-adding the constraints manually is not an option either: the database is WAY too large. 

I'm actually hoping there is a temporary bug in the import/export wizard. Each option (and you have THREE...) returns with a new error.

Googling, I found I am not alone:
