I am working on my real time project where the configuration details will be given on runtime. Based on the configuration details, the next form will be loaded and the data will be exported to the database and spreadsheets from the pop3 server. I have done the extraction work from pop3 server. Now i want to store the configuration details that are provided in the controls present in the form. I am new to visual basic 2005 and it has the .Net 2.0 Framework. I do want to create the text file as notepad and and i want to save it runtime with the details. I am in hope that you people will me.

I am trying to create a tool which I would input a word in a text box and it would search the path i give it to look for a word in a notepad file and copy the whole line to a new notepad and paste it.
i did this for now, i am able but i am able to copy all the text from the note pad and put it in a textbox for now..
Dim FILE_NAME As String = "P: est est.txt"
Dim objReader As New System.IO.StreamReader(FILE_NAME)
Dim TextLine As String
[Code].....
I am having trouble to get the command to ask them to go read the text file and copy only the line for the word I put in the input box and to put it in a new notepad.
When i debug the program and open it(inapp.exe) in notepad there a line
C:UsersendroitDocumentsVisual Studio 2008ProjectsDataTypeDataTypeobjDebugDataType.pdb
Well, is there any solution or way not to include that line when debug. I know that .pdb is important in debugging, but when the app published still there's that line. Can we disable it or there's no other way.
how you would go about saving information(username, password, security questions) in a notepad, so it can be retrieved after a program closes. i'm making a log in program in my class, but we haven't done this, so when the program closes, everything is gone. rather annoying, to have to make a accounts each time i'm testing it.

View 3 RepliesI have a listbox of items that need to be processed, and I would like to process them asynchronously on a separate thread. (Never done this before).So I created a Delegate, a Callback, called the method that does the work on the listbox items.
I am getting an exception "System.InvalidOperationException": Cross-thread operation not valid: Control 'ListBoxBlah' accessed from a thread other than the thread it was created on.
Doing the asynchronous operation for individual items doesn't make sense to me because I am only doing it to perhaps perform a large number of operations (the listbox may have 20000 items) in the background while allowing the user to do other stuff.

I often see code snippets for handling each control of a certain type on a form or panel, etc.They always start with For Each ctrl and the do a test for control type.Many .NET users are not aware, as I was not until I tried it recently, that we can LINQ on the controls collection.Below is a simple sub I created for resetting every checkbox on a panel I use as a validator.
Private Sub ResetCheckBoxes(ByRef pnl As Panel)
Dim ctrls as System.Collections.Generic.IEnumerable(Of Object)
ctrls = From c In pnl.Controls Where TypeOf (c) Is CheckBox

I want to use the following snippit.
For Each x As Control In Me.Controls
If TypeOf x Is CustomControl Then

The problem here is that not all controls have event CustomEventofCustomControl, so the complier shrieks. How do I get around this.
I've run in to a very annoying situation. At the moment I have a program with 4 forms. 3 of these forms work fine, but the fourth seems to be a dud. After clicking any one of the buttons or controls on this form it works. But if I try to click anything again, it doesn't work. I can't use my back buttons, I can't even use the minimize, maximize and exit buttons in the top right corner which are automatically built in to the program. I fear I have accidentally changed a setting, or accidentally deleted some very crucial code for this
View 8 RepliesI am trying to learn how to create Windows Forms custom controls in VB.Net by creating a .Net version of an old control I created in VB6. On this control, I have a UserControl with a Label (lblCaption), and several of the properties I add to the control should be passed to the label.This is the code I tried for the ForeColor property:
Code:
Protected mcolForeColor As Color = Color.FromKnownColor(KnownColor.ButtonHighlight)
Public Overrides Property ForeColor() As Color

[code]....
When I change the ForeColor on the control in my test project, lblCaption does change to the color I selected; however, when I run the application, the label changes back to the default (button highlight) color, and the value of the property is also reverted back when I return to the form designer.What would be the proper way to implement the ForeColor property on a custom control?

I have used delegates multiple times over the years but for some reason this very simple code isn't working:Form has one button and on textbox. Simply trying to update the textbox from another thread and although it looks fine it's not working.[code] the parameter is being passed to the DoSomething, the UpdateTextboxText is being run and gets the correct string. But the textbox itself remains blank and I'm stumped.
View 1 RepliesI'm trying to make a program which uses drag & drop functionality, however, it only works when I drop something onto the form, not the controls. If I do try on the controls, I just get the 'Unavailable' cursor.
The AllowDrop property is set in the properties bar, and I also set it when the form loads.

At work we have a pretty large web application that works by having a few pages, with lots of user controls which are nested in these pages. This is working fine most of the time but we have a problem at the moment where one of the user controls isnt working. Originally it was referenced from another project in the solution but when this wasnt working I decided to copy the file into the project and try to register it locally. It works on our development system, its only when we move it to deployment that it stops working, and I'm thinking it's something that I'm missing in the build. When you go to the page on Live the control is just missing, and no errors are generated.

I am running Windows 7 pro and using Visual Basic 2010 express.I have written a small program to switch on a USB relay which is controled by a serial port.I have debuged the program and it appears to work correctly. I have published the program and if I start it from thr run menu / desktop shortcut / or through explorer it works as expected.
However I have tried to run it by the Task Scheduler and then it fails to run as expected. I have a small section of code that checks to see if the serial port is present if not I have used messagebox.show to ask for the relay to be pluged in. In every case other than when running through the Task Scheduler the messagebox works with the Task schedulerit doesn't show the messagebox and the program hangs I have included the code I have used.

View 3 RepliesI am working on an addin/plugin for CAD software called Solidworks. I use it to batch process files (print, save, etc). One thing I'd like to add is a form that contains a stop button to stop the loop. The problem is that even if I use a background worker like I normally would for a standalone application, it still locks up when Solidworks is processing files. That's just normal operation for the program, the UI freezes when doing a cpu intensive operation such as loading or saving files, regardless of how I write my plugin. So my limited attempts at threading to get a form that won't freeze have been unsuccessful so far.
