• Visual Studio Express Editions How to suggest a value

  Hi, I have a windows form with some textboxes and other objects connected to a table adapter and I'm using a binding navigator. When the user presses the new item button, I want to suggest a value in textbox1, but the value doesn't appear because the binder deletes after I put hit there. Is there a way for me to put a value (a calculated one) in a binded textbox Thanks for your attention. Romeu Hi Romeu, There are a couple ways of doing this.  The simplest is to open up the Dataset designer and select the column you want to have a value set for.  In the properties grid there is a DefaultVal ...Show All

• SQL Server SSIS Parent/Child Package variable passing

  Hi I have having trouble getting my hands around how to retrieve variables from a parent package. I read about the Environment variables and Configuration File at the parent package level and the Parent Package variable at the child level. Here are my questions: 1. Can you only store/retrieve 1 variable in a config file at a time 2. Does the child package have to define the variables and if so, do they have to be the same names as the parent package This seems so more more complex then the DTS2000 way of passing variables to and from packages. Any help would be appreciated. Thanks in advance, Gordon Radley ...Show All

• Visual Basic Compile Error: Argument ByRef Type Mismatch

  Please, if someone experienced this captioned error, knows how to deal with it I'm writting VB6 n-tier DTC COM+ DLLs.  In one of the DLLs, I defined a few User Defined Types (UDT) to be shared amongst my DLLs. I also need to pass such UDT as a function argument in a public method of a DLL to save table data.    The initial compile was OK when all the DLLs were local in the VB6 IDEs .  Then when I moved two of the DLLs into 2003 server Component Services as COM+1.0, and tried to compile the rest of the DLLs, I got the error: "Compile Error, function Argument ByRe ...Show All

• Windows Forms How can I make my forms move faster ?

  Dear .NET I have a C# solution on .NET v2 that has a GUI project in it, The Forms are defined as "global" static objects on the Main() so that I will B able 2 use them from anywhere through MainApp.MyForm.Is_Flag_On; I start the application from the Main() like this: Form_Main = new GUI. Main_Form (); Application .Run(Form_Main); The problem is that the Forms became TOO SLOW !!! 1. You can see it when you Show / Close any Form (the controls in it are being painted on the form - first the control area is black and then it paints - like if something was overriding the OnPaint event) 2. When any of th ...Show All

• .NET Development Server GC in VS 2005 Beta 2?

  I've recently been reading up on the garbage collector in .NET and discovered that there is a workstation version of the gc and a server version.  Earlier versions of Whidbey apparently allowed the server gc to be enabled via an app.config item that looked like this...   <runtime>       <gcServer enabled=“true"/>   </runtime> I tried this with no success, so I looked into the schema for runtime, and there is no mention of the gcServer config item.  Also, I found mention of a System.Environment.IsServerGC which could be checked to see if the Server GC was being used.  T ...Show All

  I have a system.windows.forms.form with a datagrid in it. in the load method i bind a dataTable into it. and i have a method that in runtime adds some items to the dataTable after an event. i did the following: DataTable dataTable =(DataTable)dataGrid.dataSourse; DataRow dataRow = dataTable.newRow(); dataRow[0] = "some string"; dataRow[1] = "another string"; dataTable.Rows.Add(dataRow); it works, but when there are more than 10 items (the max display without a scrollBar), the scrollBar is added. sometimes it's stuck, and if not, when adding a new item there are two scrollBars, and other freak things. When adding items "slowly" it doesn't alw ...Show All
