• Software Development for Windows Vista Binding an property of activity to a property of a private member

  Hi all, After working through the Hands-on-Lab Authoring Workflows through code, I started authoring my own workflow. The workflow contains a private member of some class type,  The class itself contains members that are classes as well. Say something like: class MyWorkflow : StateMachineWorkflow { ...   private A myA; } class A {   public myB; } class B {   public string myValue; } It's for clearification: please don't mention the public accessors. The workflow uses an activity exposing a property of type string. Q1:How should I -in code- bind the property of the activity to /Workflow.myA.myB.myValue. ...Show All

  Hello, I have a question about databse setting in VWD express 2005 Beta 2. I found that I can not create a new provider for my application in ASP.NET Configuration tool.

I think thats were the problem is, in the machine config it looks for express by default, so that  needs ...Show All

• Smart Device Development Device emulator not installed?

• Visual FoxPro Data Retrieval Slow with VFP 9 OLEDB Driver and Crystal Reports 10

  I've run into a situation where my clients Crystal reports were running 4-6 hours in cases where they used to take minutes or seconds.  I determined the cause of the problem is the VFP 9 OLEDB driver.  Going back to the VFP 8 driver cured the problem (reports now run fast again). Has anyone else discovered this issue   I'd like to report it to MS, but I don't want to burn an incident when I can work around it with the old driver. There's one change and one bug in VFP 9 that may also affect the OLEDB driver. The change is that if CPDBF()<>CPCURRENT(), some tags can't be used for optimizat ...Show All

• Software Development for Windows Vista Database maintenance

  What are the methods and recommendations re maintenance of the database Mario Hi Moustafa, Thanks for the comprehensive answer, it is much appreciated. It is excellent that we can run the PartitionCompletedWorkflowInstances procedure on our own, that is definitely gonna help, as I'm sure some of our customers will definitely prefer it that way. It's also great that the SqlTrackingQuery stuff will look at the partition tables, that's what I was hoping for :) ...Show All

• .NET Development Excel Import Truncates Data

  I'm using the Jet OLEDB to import an Excel spreadsheet and I've run into the well-documented truncation problem, where text beyond 255 characters are dropped, if my column does not contain any data in the first 8 rows of my spreadsheet. I've tried setting MAXROWSTOSCAN to 0 in my connection string, and it doesn't work. According to the KB ( http://support.microsoft.com/kb/189897/en-us ), it sounds like modifying the TypeGuessRows Registry value is the only solution (which I'm reluctant to do). Is there another solution Yes, I am reading data from a spreadset into a dataset, as shown in the MSDN code samp ...Show All

• Visual Studio Team System TF30144 error when creating a project from another domain

  Hi I am struggling with a setup which consists of TFS single deployed on domain X and Team Foundation Client (and Visual Studio) on domain Y. X and Y does not know about each other since they are on diffrent nets and the DNS servers are not connected. My first problem, which I solved, was that TFS setup (or possibly SharePoint Services or SQL Server) uses computer names in configuration files. Thus, Team Explorer did not work correctly (red crosses on the documents and reports folders etc..) since computer names couldn't be looked up from domain Y. This was solved by adding the IP computer name mapping in the Windows 'hosts' file. &nbs ...Show All

• Visual Studio Team System FxCop 1.35 Naming Rules Seemingly Not Being Checked

  In running FxCop 1.35 with out-of-the-box rulese settings, I appear to not have the pascal -vs- camel casing rules being checked. I seem to have all rules selected in FxCop, so was expected the following code to give violations. Thoughts on what might be the issue I created a c# file with the code as follows: namespace FxCopTest { public class Class1 { private int TestMe = 3; private int testMe2 = 3; private int ewrddd = 4; private int m_TestMe = 3; private int ID = 4; private int IdOfMe = 3; public int TestMethod() { return TestMe + testMe2 + ewrddd + m_TestMe + ID + IdOfMe; } } } (With this code, I only g ...Show All

• SQL Server How to set a ReportParameter to the value NULL?

  Hi, how can I set a ReportParameter in C# to NULL My code is as follows ReportParameter [] param = new ReportParameter [1]; param[0] = new ReportParameter ( "LanguageID" , "1" ); param[1] = new ReportParameter ( "TopCount" , "30" ); this .ReportViewer1.ServerReport.SetParameters(param); Sometimes I want to pass the value NULL for the parameter TopCount so my stored proc can handle a special case. I tried param[1] = new ReportParameter ( "TopCount" , null ); but it doesn't work... I know, that there is a possibility for using urls to pass parms. There you have to put the parm name, followed by ":isnull=true".  T ...Show All
