• Visual Studio Find dialog in IE6 does not work after installing VS2005 July CTP Professional

  I get the following error using the find dialog in IE6 since I uninstalled beta 2 of vs.net 2005 and installed the July CTP of VS.NET 2005. "An error has occurred in this dialog" Error: 49 Interface not registered VS.NET 2005 and the help inside vs.net 2005 seem to be working just fine. Yes it was the find dialog when you hit Ctrl-F. I also noticed that printing emails from Outlook was not working anymore. Same error. Resolution: I fixed it by running the following regsvr32 actxprxy.dll ...Show All

• Visual Studio Team System MS Project integration and "WBS" field

  I have mapped the MS Project's field “WBS” to a custom field and adjusted the VSTS-MS Project mapping info. The data from the field gets synchronized in both directions and at the first sight everything seems to be working fine.     But, there is a problem with enforcing of uniqueness of WBS value. MS Project enforces the rule that each WBS value has to be unique. Since uniqueness has to do with all work items and all rules that can be set in the wit definition deal with values of the fields in the work item itself, uniqueness can not be enforced in the definition of the work item. I guess that one could handle the work ite ...Show All

• Windows Forms Tables in a RichTextBox

  I'm working on my app. and I'm trying to create tables in a RichTextBox Control at Runtime. How can I do that I already tested that saving an RTF file with Microsoft Word with a table in it and the RTB correctly displays it. Thanks in advance! I'm also looking for similar solution. Is there anyway to implement it in VB.NET 2005 I found a similar class but it's in VB6. I'm looking for a cleaner and easier solution. It seems that the author created a class and work on the RTF tag directly. http://www.vbforums.com/showthread.php p=2131031#post2131031 ...Show All

• SQL Server How to optimize data import with huge volumes and joins across data sources not all SQL Server based?

  I need to periodically import a (HUGE) table of data from an external data source (not SQL Server) into SQL Server, with the following scenarios: Some of the records in the external data source may not exist in SQL. Some of the records in the external data source may have a different value at different imports, but this records are identified univocally by the same primary key in the external datasource and in SQL Server. Some of the records in the external data source may be the same in SQL. Due to the massive volume of the import, I would like to import only the records which are different from what I have in SQL Server (cases 1 and 2 ...Show All

  Hi, I want to convert my application in java (J2EE 1.4) to J# with minimum changes. Where can I get the script Thank's Alexei (I have tryed JLCA 2.0, 3.0 and it gives me about 100,000 errors becouse it convert to C#. I don't have a time for working on errors. I read that Java can be converted to J# with minimum errors.) Generally my experience doing this always leads me to running the J2EE code under Object Web or JBoss's free J2EE server and building either a webservice or RMI invocation layer to bridge the .NET code. This does assume that you have a good MVC design where you can easily seperate the backend J2EE components from t ...Show All
