• Visual C# DllImport from C#

  Hi All, I have finished my hard job of porting a VC6 project to VC8 but now I have a problem in using functions from C#. This is the declaration: [ DllImport ( "Test.dll" , CallingConvention = CallingConvention .Cdecl)] public static extern int MyFunction(........... ); but when I use MyFunction I have following error: System.DllNotFoundException : Unable to load DLL Test.dll': Routine di inizializzazione della libreria di collegamento dinamico (DLL) non riuscita.

• Visual Studio Express Editions How to make an auto updating program?

  Hi, I am very new to Visual Basic, and programming for that matter.   I was wondering how I could make an auto updating program. I searched for it and saw some sort of components, but didnt understand how to use it. If anyone could help me that would be useful.

• Visual C++ Problem using #import with ADODB in VS2005

  I have a VS2003 project that I am migrating to VS2005. It currently compiles just fine under VS2003, but when I try to compile it under VS2005, I get a whole slew of C2327 errors. The root cause appears to be the different way that VS2005 handles nested classes. However, the code that the compiler is having a problem with is generated by VS itself as a result of a #import: #import "C:\Program Files\Common Files\System\ado\msado25.tlb" rename( "EOF" , "adoEOF" ) rename( "BOF" , "adoBOF" ) rename_namespace( "ADODB" ) An example of the error that I receive is: error C2327: 'ADODB::_ADO::Properties' : is not a type name, static, or enumerator Has anyone else encoun ...Show All

• SQL Server Problem Deleting Duplicate Data

  I have a table that contains more than 10,000 rows of duplicate data. The script below copies the data to a temp table then deletes from the original table. My problem is that after it runs, I now have 122 rows of triplicate data (but dups are gone). If I rerun the script, it doesn't see the triplicate data and returns 0 rows. I've use three different versions of delete dup row scripts with the same result. There are no triggers or constraints on the table, not even a primary key. What am I missing ------------------------------------------------------------------- /********************************************** Delete Duplicate Data **********************************************/ --Create temp table to hold duplicate data CREATE TAB ...Show All

• Visual Studio Express Editions dates and null values

  My column in sql is of a date data type. I have a textbox that a user can enter a date when certain parameters in the program are met. On occasion a date does not have to be entered in the textbox. This is where I have a problem. The column can accept null values but I am not sure how to program this part. I have a date variable = cdate(txtbox1.text). If nothing is entered in the textbox I get an error message of "can't convert "" to a date) Any help would be appreciated. just skip it in this case or just give a DBNull value to the datatime parameter in SQL when you are creating a parameter collection or in your INSERT/UPDATE statement. ...Show All

• Visual Basic Replace in SQL on Access Database

• SQL Server Is it possible to have more than one table footer rows ?

  Well, we can add another table footer row by right-clicking on the footer row of the table and select, Inser Row Above, or, Insert Row Below. But, I want to set different values to same properties of rows. Such as; Row3.RepeatOnNewPage = False Row4.RepeatOnNewPage = True What do you say -SMang the Frustrated Developer SMang, You can't hide your table rows independently with the RepeatOnNewPage, but you can set the rows "hidden" property to true or false. The catch here is that you will need to tie it to a toggle item. Ham ...Show All

• Windows Forms DataBound DateTimePicker/ComboBox Events

  Events on Databound controls that have their Visible Property set to false at DesignTime do not fire events. I was told this was part of their design. I accept that fact. But controls that have Visible set to true at design time and then Visible gets set to false at runtime, will fire events even though Visible is false. Question 1: Why does having Visible = false at Runtime and Design time behave differently Question 2: What internal happenings occur that make the control start firing events and can I trigger this internal change (i.e Can I force a Control with Visible = false at Design fire its events or visa versa can I make a control with Visible = false at runtime not fire events) How to Repeat: I attached a simple ...Show All

• .NET Development Binary serializing an object which composites an interface field without serializing the interface implementor

  I want to serialize an object which composites an interface. While serializing the actual class, I do not want to serialize the object that implements this interface. I just want to keep its reference and pass it to the serialized class. Here is an example [ Serializable ] public class Sample { private string _name; private IInterface _sampleImplementation; public Sample(IInterface interface) { _sampleImplementation = interface; } } When I use custom serialization by implementing ISerializable, in the GetObjectData method anything I add to the SerializationInfo gets serialized automatically.

• .NET Development Notification when managed thread exits

  The first managed frame on a thread is usually 'Main'. Can I be notified when this frame 'steps out' I have tried to create stepper on that frame, but it does not seem to work. I need this for two things: I would like to 'inject' a call to { System.Console.WriteLine(“Press any Enter to continue...”); System.Console.ReadLine(); } so that when a console application exits, I can still see the output. Application is kept alive because of worker threads. When the frame 'Main' steps out, ExitThread callback does not occur because native thread is still running. However, I want to remove the thread from my data structures anyway so that I do not attempt to access it. I'm ...Show All

• Visual Studio Team System Custom Control Question - Is there a way to capture the work item save 'event'?

  Hello, We are creating a custom control to enter time worked on a specific work item. I have the control created and displaying in the work item. If possible, I would like to capture the work item save event to save my time entry instead of having a separate save button within my control. However, it appears that "FieldChanged" is the only work item event that is available to me. I've thought about leveraging the WorkItemChangedEvent from TFS somehow, but this feels a little too clunky. Are there any other approached I am missing Thanks in advance ... bbossi In this case I would prefer subscribing to WorkItemChangedEvent and implement your custom logic on receiving a notification ab ...Show All
