Winform message boxes not appearing after upgrading to server 2003 r2

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :Windows Application
We have an issue where some of our nested controls are not displaying messageboxes without hiting the Alt key. Example a users selects a drop down list option from our custom treelistview control. after making there selection they tab or move the cursor off and click. In the afterlabeledit event we try to present a couple different messageboxes. They come up, but are not visible on the screen. You have to hit ALT to make the message appear. it looks like something is taking focus away, but it is a message box and should be topmost. Any help would be appreciated.

Upgrading Windows 2003 Server with .Net Framework 2.0 SP2


We have multiple websites deployed onto Windows 2003 WebServer running under .NET Framework 2.0 SP1 version and now we want to upgrade it to .NET Framework 2.0 SP2, so just wanted to check that after upgrading the .NET Framework on the server do we also need to re-deploy the websites by recompiling them in .NET Framwork 2.0 SP2 version or it's not necessary as they will automatically start referencing the latest assemblies?

Your early response will be much appreciated...


Upgrading from SQL server 2005 to 2008 and get an error message

I am halfway through the process and get this error message "Use the Reporting Services Configuration tool to configure the database source name (DSN) and connect to the database." on the Reporting Services Authenication page.

This is the runtime version that is distributed with Amicus Attorney, a lawofffice management program.

I can barely spell SQL and have no idea what this is about, but Amicus told me it wasn't their issue.

UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

Windows Server 2003: Discover Improved System Info, New Kernel, Debugging, Security, and UI APIs


There's a lot to say about Windows Server 2003. First of all, it's the first operating system with built-in .NET Framework support, and it's the first 64-bit OS from Microsoft. But wait, there's more! There are lots of new features and APIs in this version as well. For instance, Windows Server 2003 features Hot Add Memory and a number of other arcane new tidbits. There are new APIs for handling threads, directories, and files, and new features like the low fragmentation heap for managing memory and system information. There's vectored exception handling and new UI APIs as well.OS internals expert Matt Pietrek takes a look at the additions he finds most interesting and useful so you'll have a good place to start when you dive into Windows Server 2003.

Security Briefs: Exploring S4U Kerberos Extensions in Windows Server 2003


Building Web sites that provide services external to the corporate firewall is tricky. Usually it's not desirable to grant corporate domain accounts to external clients, and from a purely practical standpoint Kerberos does not work well over the Internet due to the typical configuration of client-side firewalls.

How to Add Custom SOAP Headers Into The Server Response Message in WSE3.0?

Hi Dear All, Assuming I am the service provider, may i know how many ways are there to insert a custom header into the server response message? So far I tried several ways, and it can be done in custom SoapFilters (by playing with SOAPEnvelope object), and SoapExtension (SOAPMessage object). Just wondering if this could be done at web service class by specifying a SOAPHeader attribute, just like adding a SOAPHeader into the SOAP request message at consumer side? If can, it might be much smarter than SoapFilter and SoapExtension.   Thanks in advance!   Best Regards, Charles

Post Upgade task, Upgrading SSIS Pacakges to SQL Server 2008.

Hi, I am trying to upgrade sql 2005 packages to sql 2008 after doing in-place upgrade of DE and SSIS. Can I know what packageformat column in msdb.dbo.sysssispackages refer to, as according to http://msdn.microsoft.com/en-us/library/cc879336.aspx the value should be 2 if the package is in sql 2005 and it should be 3 if it is upgraded. But I am seeing only 0 or 1.   Can I know any other method to figure out version of the ssis packages? I am having issues upgrading SSIS Packages from 2005 to 2008, using SSIS package upgrade wizard.   Thanks for your help. Regards, KRanp.

Server Cache Issue - .Net 2.0 / Oracle 11g / 2003 Server / IIS 6.0

Hi All,We are working on a web application developed in C#, nHibernate and with Oracle as back-end.WebServer and Database are on different machines.Application is more or less accessed by 500 users all the time.Recently we found that some of the controls within MultiView Tab contol were not working as expected. Basically, data is not getting saved.For instance, if there are 5 tabs and in the first tab if we change an option in the dropdownlist, in the autopostback event, the new value should get saved to database. If we navigate to another tab and visit the previous tab, the new option should remain there (reloading the data in the page_load, preRender events).But once we restart the IIS, all this functionality works as expected.Even if there is some database issue, like foreign key violation etc, application is behaving weirdly and once we fix the database issue, we still need to restart IIS to clear cache for the application to behave normally.I am not sure if any of you ever faced this issue but please let me know where to start analyzing this issue?Thanks in advance.ys

I was running a MIS reporting solution on a single server running MS Windows 2003 Server and Sql Server 2005. The solution was built using ASP.NET 2.0 on IIS 6.0, Sql Server DB & SSRS.

SQL-Server 2005 x64 / windows server 2003 x64 crashes during file copy

Hi We are running: Microsoft SQL Server 2005 Standard - 9.00.4294.00 (X64) Microsoft Windows Server 2003 R2 Enterprise x64 We have gigabit interface. Today we copied a file (using robocopy) from our databaseserver to another server (backup-server). The copy was started from the backup-server and source were specified using UNC. The copy were using about 20% of the bandwith (about 200Mbit). During the copy, sql-server reported several errors, for example: AppDomain 15 (mp.dbo[runtime].14) is marked for unload due to memory pressure. The client was unable to reuse a session with SPID 75, which had been reset for connection pooling. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message. ***Stack Dump being sent to [PATH\SQLDump0005.txt Resource Monitor (0x1384) Worker 0x000000008000C1C0 appears to be non-yielding on Node 0. Memory freed: 0 KB. Approx CPU Used: kernel 15 ms, user 218 ms, Interval: 428541. So to me it appears that sql-server crashed during a file copy. We have 27 GB ram. With 24.5 GB dedicated to SQL-Server. The files we copied were quite large, some over 50GB. I found a similar issue about this: http://support.microsoft.com/kb/920739/ Do you think the issue above could be the cause of the sql-server crash? ///Patrik

Sharepoint 2003 + Windows Terminal Server 2008 + Office 2007 problem?

Hi, We have a customer where some users runs Windows Terminal Server 2008 with Office 2007. They open documents from a Sharepoint 2003 site. When they open an excel sheet they get a button in the document which says "Server workbook: Click edit workbook to edit this workbook" and there is a button: "edit workbook" The users clicks "edit workbook" but get an error message saying there is no connection to the server.  They are able to edit the document, but not save it back to the sharepoint site. Most other users work on their local computer with Office 2003. Here, everything works fine and there are no button/message stating its a server workbook.   Is this caused due to some compatability issues between Sharepoint 2003 and Office 2007?   Best regards, Thomas Hansen ErgoGroup AS
