When debugging a program and then we take it to a line breakpoint,then I want to modify the code again.but could not and such message appears in the image which I attach.What can we edit code program at the time of the process of debugging.This can be done in visual basic 6 ide?
Prior to VS 2010 I was able to debug VB6 client code from the .Net IDE by setting "Start External Program" to vb6.exe (full path), or attaching to the running vb6 executable via "Tools->Attach to Process" and have execution stop at the required breakpoints in my .Net code.
Now with VS 2010 I seem to be only able to accomplish the same by setting the target framework to 4.
Is this a bug in VS 2010, or is there a switch/option that controls this?
I installed VS2008 ona newVista Ultimate 64 Bit machine. Works great. But if I try to change some VB2008 code while debugging, the system says, "Changes to 64 Bit applications are not allowed". Why is this? And will programming on a 64Bit machine always be hampered like this
On my last machine I had created a way to see a GUID variable while debugging by hovering over it. I don't remember what it was (a visualizer?). I have a new 64 bit machine with vs2008 - is there anyway to mouseover a guid value and have it appear? What makes guid's so special that their value doesn't show like most variables?
I dont where am going wrong but when i am programming i will make some changes to make code and form e.g add a button or something. Then when i go to debug my program my change dont appear and its been a couple of days and my changes still dont appear when i debug my program.
When I end my app by pressing the stop button in visual studio, is there a way for that event to trigger some exit code? I'd rather do that than include a visually distracting quit button.
Better still would be to program some kind of key sequence, eg control + q to trigger some quit code so my app can exit cleanly. Is this possible? I wouldn't know how to program a key shortcut but it might be handy.
I've seen this great example of serial communication in VB.NET[URL]..I try to use it in a project I am working on but somethings are not clear to me.1: Now the send and received data is shown in one RichTextBox but I would like to split this into two RichTextBoxes (RtbSend and RtbReceived).It is unclear to me how and were data is assigned to the RichTextBox?
2. the received data is shown in the Richtextbox as one long line, I would like to get a new line for every send message.So for example: I I send "test" four times, I would like to see:The example describes that "comPort_DataReceived" is executed when data is waiting in the buffer. Where can I see the eventhandler responsible for this? How does it know data is waiting?The problem is this kind of coding is a bit to difficult for me. I want to understand the code before I implement it into my project. I understand most of the code but this is unclear to me.
mostly the data inside the datatable is always typed by ourselves, while in this case, i want the computer itself do caculate or whatever and then input in this table and finally the chart will get the data inside the table and then draw the line automatically.is there any sample codes for me to know....(Above is just a simple idea, actually my project is to record the time spent in 2 status(working and idle) and then do the database table. but the GUI should look similar to the image above)
I am converting an old asp project to a new .NET project. Now, all vb code are inside aspx files, and we are on the process of moving all vb script from aspx files to .vb files. My problem is, I can't debug the vb script inside most of the aspx files. All my friends don't have this problem. I think the problem is with vb text editor.I am using Visual Studio 2008. Is there anyway, I can make visual studio understand that aspx files have vb script inside them.
I have some VB6 code that instantiates a class which handles events that are being raised from a VB.NET component. The VB6 is pretty straightforward:private m_eventHandler as new Collection
public sub InitSomething() dim handler as EventHandler set handler = new EventHandler m_eventHandler.Add handler m_engine.Start
[Code]...
My problem is that when I debug the VB6 program, the first time InitSomething gets called, the event will not be handled (the VB6 event handler is never entered). Subsequent calls to InitSomething does work.
Everything works as I would have expected when I run the program outside the debugger. At this point, I'm not even sure if this is something I should be worried about.It may or may not be relevant but the VB.NET was converted from a VB6 using the Visual Studio code conversion tool (and subsequently manually cleaned up).
If I wanted to say, alter the code definition of the automatic property X (at runtime, perhaps in Sub New), such that I could throw the PropertyChanged event
I've written a for loop to generate several new text boxes and numericUpDowns when the application is run.
The text boxes / numericUpDowns are generated with a 2-dimensional array. My question is: How do I handle when the text boxes / numericUpDowns are modified?
If you would like the code, just request it and I'll add it here.
Well, I've read (and learned) that the finally block doesn't always execute its code (even apart from pulling the plug).FYI For more information, see try catch finally question
When I am in break mode, I cannot update code.I receive message "Cannot currently modify this text in the editor. It is read only." Can anyone explain why I get this message?
i wrote a piece of code to write some data to a card reader, and read back from that device, filling a form with the data (after reformat).When I step through the code while debugging (using F5, F8 for stepping forward) the form is filled correctly.However, when I run the code (Ctrl-F5), the program seems to hang for about 5 sec and then throws an exception: 'Length should be >0' When looking further during debug - it seems that the program calls 2x the Sub Frm_Read_Display(). I
Imports System.Windows.Forms Imports System Imports System.IO.Ports Imports System.Threading
There has to be a setting for this somewhere, but for the life of me I can't find it. When I "Start Debugging (F5)", if there is an issue with my code, I get a "Build Failed" notification, in the lower left of my screen. I would like to be directed to the location of the failure. So far I have been lucky and have been able to find the offending code but this is getting scary .
I'm having to write a reporting application that gets information from some Interbase servers and it also has to work on Vista as well as XP, I'm using to connect Borlands Data Provider.[code]My Issue is that debugging on my xp Machine the dataset gets filled, debugging on my vista box it fails ("Interbase provider initialization failed"), my initial thought was that this could be UAC related but I've compiled the application and 'ran as admin' and still same issue. (by the way it failes on the line Dim da as BdpDataAdapter...)
I got the below code from Deborah Kurata one of the msdn moderator on her webpage. Her code is to save the form size at runtime but i would like to modify it to save the buttons which i have dragged and drop. I tried to modify the code but i tend to when i put the Dim theButton = DirectCast(sender, Button) under the form load method. It put there cannot cast object. something like that.
Public Class Form1 Dim tm As New Timer Dim Index As Integer = 0[code].................
SELECT ContactID, FirstName, LastName, Male, Female, Email, Address FROM Contact WHERE (FirstName LIKE @FirstName + '%')
The above query works and returns values on first names that begin with whatever item I type in a text box.
How can I modify that code to search for items containing specified characters instead of just searching for items that begin with the specified characters. I would still need to use a wildcard because it is a search field. see below for an example
For example can I query the FirstName column to display people who's name contain the letters "an" in that order a before n but anywhere within the word e.g.
I am working in vb express 2008. I got some sample code from the site www.vbhelper.com and tried to implement it as it is. Debugging of the code gave following errors:Error 1 'Protected Overrides Sub Dispose(disposing As Boolean)' has multiple definitions with identical signatures.

I'm running VB2008 on Windows 7; I've written out a ver simple piece of code:
Option Explicit On Module
[code]....
When I run or debug the code, it asks for the First Number and then just completes the running of the program without asking for the second number and uses some random number. The console.readline() doesn't work either, the console window just disappears.
I am trying to create a ListBox in which every item can have it's own context menu. To do this I have created the classes as shown in the code. Now when I test this, I get the following error when adding an item to the collection using the 'Add' method:
INTERNAL ERROR: Unhandled exception in Debugger::HandleIPCEvent. Event ID=0x246.
I'm just starting to use VS 2010 - not sure if this was available in VS 2008 - but I was reading about the Hosting Process you can start for debugging.This allows you to call methods and jump into breakpoints in them without starting the whole app running.
I had written an app that runs at ever login (win7). So as it is running I load 2010 Express and try to test some things, but it comes back and says "The operation could not be completed. The Process cannot access the file because it is being used by another process."How is that possible when the 2010 Express should be fully contained? I have even named it completely different from the originally application. Am I missing a setting?
