I have written a program for cleaning my pc. I want to be able to start the Form1 (which opens the entire program) from the start menu. And I would like to run Form2 (which runs just the scan) from the context menu of the recycle bin. How can I open Form1 from one shortcut and Form2 from another?

Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.
Running total = 329430.75
New Withheld Amount = 710.79
Running total = 330141.54
[code]....
As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..
The only programming language I know is C++, and I would like to learn some others, specifically Visual Basic. So — what are some good beginners tutorials for VB, and what others languages would you suggest are good ideas to learn?
View 5 RepliesIn a program that I'm responsible for, we want to start keeping track of milestones. These milestones are quite simple and consist of a unique identifier, the project they're assigned to, a description, and a date that they should be accomplished by (or not, if there's no concrete due date).We use a slightly modified Model-View-Presenter architecture, and currently I'm passing this list around through the presenters, but it seems fairly clunky, so I was wondering:What's the best way to make this list available to all the presenters/views that need it?We're using VB.NET 3.5, and I was toying with the idea of making this a shared property of the main presenter, but it does seem like that adds some unnecessary coupling.
View 1 RepliesI have created two structures, one named "Product" and the other named "Item". These structures are quite similar but are at the same time quite different from each other. The structure definitions are as follows. Ultimately, I declare arrays in my containing class which access these structures as a type. Their declaration: "Products() as Product" and "Items() as Item". All has been fine and dandy until one day, I go to change the items Enabled() values, and something happens. Not only does it change the Items(index).Enabled(index) value, it does it on the corresponding Products(index).Enabled(index) value, even though it was never specified to do so. Also, nowhere in my coding have i defined this sort of thing to occur. It is rediculous, because I watch it happen. I turn on the watch window, and debug one step at a time, and every time, I watch the Item line step, I look down at the arrays of products and items, and both values have changed. How do I get this to stop, and only change the Item.Enable value??

I know that title is kinda miss leading, but i couldnt figure out another way to explain it. I know theres a way, but I dont know how to do it.Ive got a Save code that I have about 5 differnet times in my application. How do I make it so that I can just type in something like Do Save, and it locates the save code and follows it through, then returns to where it was.

I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?

I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

View 10 RepliesWhen I setup the event using DDay.ical I can successfully send the events to a user's outlook. The problem arises when multiple events are setup at the same time. When this happens all emails are updates to the original task, not new tasks.
I tried adding a name to the event using the .Name property, which results in the event email being an unsupported calendar invite.
I'm attempting to send an email to multiple recipients, via the System.Diagnostics.Process.Start() command. The string I'm using looks like this...
System.Diagnostics.Process.Start("mailto:Test1 <test@nowhere.atall>; Test2 <test2@nowhere.atall>;")
The first email shows up correctly in my email program (Windows Mail in this case), but the second email does not show up. If I get rid of the brackets that separate the email from the recipient name (getting rid of the recipient name from the string), then both email addresses will load without problems. It's only when the brackets are included that the problem occurs. I've tracked the specific problem spot to the closing bracket on the first email name. For some reason, everything that follows the closing bracket is ignored.
