• Software Development for Windows Vista Distributed Workflow using WF

  Hi, I have a sequential Workflow which consists of activities say, A B and C. I need to execute them in a distributed environment i.e. Activity A and C on Machine A and Activity B on Machine B. Is there a built in support to realize this in WF and if not, are there ways to realize this using the runtime services provided in WF Rgds Giri GiriKrishna, Yes you can implement such behavior using wait points(delay or handleexternalevent), where after activity A execution WF will be persisted. But you need to update your custom app specific store after completion of your activity A with this information that acitivity A has completed. After this as you said in your point 2), pass the instan ...Show All

• Visual C# Text Box Display (Without building public interface)

  Hi I have 2 window forms. First form has a text box and a CmdButton. My second form has one text box. Both the text boxes are in Public modifier. My first form will show as default. My goal is whenever I type anything on Textbox1 (form1) and press command button, my first form should be closed and second form should be on visible, on that time, the contents which I typed on the First form’s text box will appear on the text box of my second form. Like this public void BtnSend_Click( object sender, EventArgs e) { SecondForm SF = new SecondForm(); SF.AllowDrop=true; SF.TextBox1.Text = This.TextBox1.Text; This.close(); SF.show(); SF.TextBox1.Focus(); ...Show All

• Windows Forms Use existing columns in datagridview when binding?

  I'm binding a datagridview in runtime, but i would like to be able to design the columns in designer. Of course thats not possible since the designer does not know what columns it's bound to before the application is running. Is it possible to add unbound columns to the datagridview, and when setting the bindingsource in runtime, make it reuse existing columns if they have same name for instance I'm fairly sure that i have done this before, but i can't remember... If you specify columns with the designer, then the columns in fact exist as objects on the form at run-time and you can assign the database column-name into the DataPropertyName of the object, as in dgvColName.DataPropertyName="mydbcolumnna ...Show All

• Visual C++ String Table?

  Hello, I have created an empty project, and managed to write some code that will create an empty window... When I was experimenting, I thought that keeping ALL the text within the program in a string table (as a resource)... Would that be good Is that too inefficient Anyways this this the code for the window: =========code============== #include <afxwin.h> class MFC_Tutorial_Window :public CFrameWnd { public: MFC_Tutorial_Window() { Create(NULL,_T("Test Window")); } }; class MyApp :public CWinApp { MFC_Tutorial_Window *wnd; public: BOOL InitInstance() { wnd = new MFC_Tutorial_Window(); m_pMainWnd = wnd; m_pMainWnd->ShowWindow(SW_SHOW); return TRUE; } }; MyApp theApp ; =========code========== ...Show All

• SQL Server DrillThrough to Details.... Programming

  Hello, In the article on microsoft : http://msdn2.microsoft.com/en-us/library/aa175980(SQL.80).aspx It explains how to use ADOMD and ADODB to retreive detailed information for the cell returned from the analysis service. For example, detailed information (such as student ID, First name, last name.., etc) about the student that's in location Cincinnati. However, this example is quite old and doesn't apply to the new ADOMD.net (Microsoft.AnalysisServices.ADOMDClient). I tried to find any example on the web, but without success. Is there a way to retrieve underlying detailed information Any help is greatly appreciated. Thank you very much, Annie Finally, I found some resources online and w ...Show All

• SQL Server Debugging DataFlow components

  I'm trying to do design time debugging of a dataflow component that I developed. I'm clearly doing something wrong, but I can't figure out what so I'm looking for suggestions if anyone has had a similar issue. The reason I think I doing the steps correctly is that I can debug other components. However, that set seems to be limited to those developed in C#. My component is developed in VB. Shouldn't matter, I wouldn't think. As a test I tried to debug other VB components from the SQL Server Samples and I have the same problem with them. Last one I tried was ChangeCaseVB. Though I just tried ChangeCaseVS and it didn't stop for me either... The problem I have is when I drop the controls onto the design surface in the second instance ...Show All

• Windows Forms Appending rows to a bindingsource?

So I want to load all rows from table a, then add all rows from table b ( using a query of course ). How can i do this thanks, -stellar Hi, You should use Merge method from DataTable or DataSet as per your need. Here is an example, private void MergeTwoTableAndDisplay() { SqlConnection conn = new SqlConnection (); conn.ConnectionString = "data source=localhost;initial catalog=Northwind;integrated security=SSPI;persist security info=False;packet size=4096" ; conn.Open(); SqlCommand cmd = ...Show All

• Visual Studio 2008 (Pre-release) Closing WCF ServiceHost object ?

  Hi, I recently ran into a strange problem that I cannot find anything written about yet. When I run a sample console program with one simple WCF service and call the Close() method on the ServiceHost the following happens - if a WCF client has started a session by connecting and made at least one call to the service): 1) The ServiceHost method Close() gets stuck for about 10 seconds (! ) and then the call returns without any exceptions throw (and the service finally exits nicely). 2) On the client side - if a call to the contract is made while the server side is stuck in the Close method - I immediately get an unexpected System.ServiceModel.FaultException with the description: "The server was unable to process the request due ...Show All

• SQL Server SQL Server 2005 - Lock request time out period exceeded

  I have a updlock on a row using sp1. When I go to update that row in sp2 in the same transaction I get Lock request time out period exceeded. I do have Lock_timeout set to 0 in my sp2. This doesn't happen with SQL 2000. Its only occurring in SQL 2005. Why does lock request time out period is exceeding when I already have a updlock on the row. And it happens only in production environment - may be because of high traffic. Here are the details : Declare @opVar int Begin Tran Exec sp1 @opVar output If @opVar = 0 Begin Exec sp2 Commit End Else Rollback End sp1 : @opVar int output SET @opVar = 0 -- Bunch of selects with updLocks . .
