• Windows Forms Can't get DrawItem event any more, in some special case

  This interesting thing was found by use of DebugView to monitor the all events. Suppose that there are 2 controls, one is propertyGrid, one is myListBox, which is a subclass of ListBox. myListBox uses OwnerDrawFixed mode, so it has to draw all items manually. However, in some mysterious case, I found that when I repeatedly opened and closed the propertyGrid, myListBox may never raise any DrawItem event. I output all events to DebugView, then found that WM_PAINT was there, but didn't WM_DRAWITEM. Also it can't restore from this bad status no matter what I did (move, refresh, resize, maximize, minimize...), until I recreate another myListBox. I think WM_DRAWITEM is nowhere to be manually emitted, since it's managed by control. ...Show All

• Visual Basic Difference between C#.net and VB.Net

  Hi What is the difference between C#.net and VB.net Hi,  In the sense of producing code, lots, but they can both be used to produce a final project or solution.  I've heard that the C# or C++ .net versions can do a few tricks easier than you can do in VB.Net, possibly the reverse applies in some scenarios. Some folk going into a programming career end up learning more than one .Net programming language. Visual Basic (VB) .Net code is far easier to read for most people as it is using more English words. Take a look at http://www.programmersheaven.com forum areas to see code samples etcetera to see what i mean. C# area >> http://www.programmersheaven.com/zone30/index.htm     C ...Show All

• Visual Basic microsoft.data.connectionUi

  i want to know if i can redistribute this dlls: Microsoft.Data.ConnectionUI.dll Microsoft.Data.ConnectionUI.Dialog.dll These files are located in the directory where your VS.NET is installed under \Common7\IDE And the long answer is You seem to be implying that the long answer is maybe or unknown. It seems silly to limit .net developers to using old activex connection dialogs when a perfectly good one is available with visual studio. The most perplexing part of this limitation is that the dlls are freely available as part of Visual Studio Express. So I can redistribute them but by getting my customers to install Visual Studio Is there a re ...Show All

• .NET Development CAS and role based security implementation

  Hi all, I am bit confused in role based security and CAS while implementing the same in .net.

• SQL Server groups in reports

  I have grouping in my report...   when the user selects print...is there a way of opening expand all the grouping   Thanks Hi- I don't believe there is a way to control the toggle state when printing. A suggestion might be to add a parameter, name it "Expand All" and set the initial visibility state of the group to the value of the parameter. Users would need to set the parameter to true and then print. -Jon ...Show All

• Visual Basic Reading/Writing Arrays

• .NET Development SerialPort Class Help DataReceived

  I'm using the DataReceived from the V.2 .NET SerialPort class. I'm communicating with a microprocessor board and i can write to it fine. I'm having trouble reading from it. It sends a single byte at a time without an EndCharacter. I can see the byte being sent on my oscope and with an older Turbo Basic program it does read the byte. My problem is that my DataReceived event isn't being thrown. I have my ReceivedBytesThreshold set to 1 and i still can't see anything. Here is my code just see if the event can be thrown: Private Sub SerialPort1_DataReceived( ByVal sender As Object , ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived MsgBox( "here" ) End Sub Here is my code to t ...Show All

• Windows Forms transfer all data

  I am working on a Windows Forms application (C#) that has two databases, an odbc database(Paradox) and a Windows mobile database (sdf). I need to copy all records from the CUST table in the Paradox database to the Clients table in the Windows Mobile database Clients table. Is there a way to do this using the tableAdapters or in SQL I am more familiar with Borlands QBE queries so SQL is pretty new to me. Is something like this possible from one database to another Or will I just have to loop through each record in the CUST table and then insert each row into the Clients table in the windowMobile db in code in my app. INSERT INTO "Clients.DB" (CODE, LINK) SELECT D1.CODE, D1.LINK FROM "CUST.DB" D1 Thanks Jon Str ...Show All
