VS 2010 - End A Statement - Doesn't Close You Program Properly And Hides Errors
Jan 6, 2012
End A statement which as far as i know doesn't close you program properly and hides errors. Right now i'm being forced to use end because i don't know how else to close my program properly. I'm not sure where my problem is but some of you should be able to fix it. I'm trying to make a game using directx with a game loop. This code is the skeleton of what i'm making.
Public Class Form1
Private ProgRunning As Boolean = True
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Show() 'Make the form appear
Me.Focus() 'Give the form focus
[CODE]...
This code runs alright because end is being used but if you rem end out the error which it's hiding comes out. The error is "Object reference not set to an instance of an object." I'm not totally sure but i'm guessing that the error is refering to the form.

Basically my script doesn't properly close Word, and it still remains open. Then when I try to run the script again it says its Read-only as its opened..What I need it to do is - put the TextBox1 info onto the DOC - and print it. I don't want it to save, as it's a template. I've tried saving it somewhere else as a "temp" to get rid of this read only but it still doesn't work.Another issue also is that it's trying to close the document before the printing dialog disappears, so I've had to put a timer
Public Class Form1

The form is an About Us form so has nothing on it only a text box and a OK button.
[Code]...
Why won't the button close the form? I'm puzzled, I tried another button just in case with the same result. UPDATE: I set a break point on Me.Close() and it isn't reaching it when I click the button, I created a new button and the same thing happened.

I'm trying to download a file, which works fine, but the progress-bar is showing me no progress and because of that the form doesn't close. Could anyone tell me what is/could be wrong with my code. The weird thing is that the same code is working in my another app. [Code]

I have set up a notify icon for my form. I want to make it so that when the user clicks the close button that it doesn't close the form it just takes it to shows the notify icon. They can exit the program from the notify icon. Can someone tell me how to keep it running?

I have a situation where me.close() doesn't close the form. I have a form with a button with the code seen below. What happens when the button is clicked is the new form shows, but the original form(calling form) is still there. When I go into debug mode, I can see the me.close() execute, but nothing happens (calling form stays open). When I close the second form both forms close. If I comment out the call for the second form to open the first form closes without problem.

I've written my own program to assist other engineers with their work at my company. Some people have been able to install the program with no problems, others can't seem to get it installed and I'm having trouble figuring out why. They install .Net Framework 4 as this is the Target framework that was setup in the file, although I don't think I fully utilize all the features yet and not sure when I will. I will post the portion of the log that contains the error. If anyone decode some of this so I can track down the problem. I'm not sure if downgrading the necessary version of .Net would work or not, but didn't want to be changing that unless there was a good reason too.

father.getheight 'compiler writes: Panel class doesn't support getheight, but I've already converted it to a Control with CType!end sub of course if i dim father as Control it works perfectly, but in my case father may be other objects as well that aren't controls so I had to dim father as a general object, is there a fix so i could properly convert father into a Control object?

My problem is when i use this schema.ini, the 9th, 10th and 11th column of the second row of the csv file doesn't read properly if there's a special character in it (it supposed to be telphone number), i think because the row above is returned as a number(integer) because it's pure numeric:

I have an application that runs perfectly on XP. When I run in on Win 7, it works perfectly when I run it in the IDE but when I deploy it, the application starts OK but some of the functions don't work as they should. I know it could be anything but does anything stand out?

sometimes my application will remain running after I close it. If I check the task manager, the process is still running. Is there anything specific that could cause this, or any way I can make sure to close the program completely?

For some reason, it seems that the outer block doesn't seem to update recursively, as I expected it to. I want the loops to add all directories within "C:UsersDrise"to the array internaldirs(). Any advice on the correct way to do this, as it seems I'm doing it improperly?
Static internaldirs() As String
internaldirs.add("C:UsersDrise")
For Each internaldir As String In internaldirs

I'm trying to figure how to properly use an If-Then statement in a project that I'm working on. What I'm attempting to do is have the user input a variable such as 1-4 and have it produce a price and the user inputs a variable such as 5- ∞), have it produce a different price. I'm getting confused as to how I'm supposed to incorporate an If-Then statement with this. Basically what this assignment is is a number of units (1-4) or (5-∞) and then charging $10 or $9 respectively.

I thought Me.Close() works, but hey I'm a noob at this. Right now I'm using:
Form2.Show()
Me.Dispose()
Me.Close()
but now that I've published it, I have to pull up my task manager and do end process to actually close the app. This wasn't a problem until my office started using a public drive and everybody was using the program at once. An error popped up saying that the connection string wasn't initialized, but it worked on the computer that opened the app first. Maybe the real issue isn't properly closing the form, but that is annoying that I have to use my task manager to close my app.

I am making this program for a school assignment but it has errors when calculating
Private Sub frmReceipt_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'When this form is loaded, assign the date to the date label & start the timer
lblDate.Text = Date.Now
[CODE]...
So if counter finishes, execute the following code
If counter > 4 And km >= 1 And kmcashset = 0 Then 'If there is still kms to calculate 'And kmcashset = 0
kmcashholder = kmcash
km = km / 5
[CODE]...
And if I add counter = 0 and km = 0 at the end of that "If counter > 4 And km >= 1 And kmcashset = 0" Then it doesn't calculate anything correctly. I supply it with 9 for Distance and it returns 4 for excessdistance which is correct but returns 7 for excessdistancecharge when it should be 4! When I supply 23 for Distance it returns 18 for excessdistance and 11 for excess distance charge which is correct. (???)
Excessweightcharge calculates correctly.
I think it may be the way I'm implementing it, through the use of AND or maybe it's because it's in timer tick?
-Minimum charge of $5 which covers 10 kgs for the first 5 kms only
-Each kg over 10 kgs incurs a charge of $0.50
-Distances over 5 kms incur an additional charge of $1 per km up to 10 kms
-For deliveries over 10 kms, the extra distance should be rounded up to the nearest 5 kms and charged at $2 for each extra 5 km block.
EXAMPLE 1:
Packet weighing 9kms travelling 9 kms
Standard charge for first 5 kms ($5.00)
Weight less than 10 kgs so no extra weight charge
Extra distance charge 9 - 5 kms = 4kms x $1 = ($4)
Total delivery charge = $5 plus $4 = $9
[But my program returns 7 for excess distance charge]
EXAMPLE 2:
Packet weighing 33kgs travelling 23 kms
Standard charge for the first 5 kms ($5)
Excess weight 33 - 10 kgs = 23kgs x $0.50 ($11.50)
Extra distance (23 - 5kms = 18kms):
18kms ( 5 to 10 kms at $1/km) = ($5)
13kms (18-5)/5 = 3 (rounded up) x $2.00 = ($6)
$5 + $6 = $11
Total delivery charge = $5 plus $11.50 plus $11 = $27.50
[My program calculates everything correctly]

I'm working through a programming project, which should be quite easy but im stuck right at the start (relatively new to VB). I have a textbox (named textbox1) and a checkbox next to it. I want the checkbox to be ticked (.checked) when ever the value in the textbox is between 1 and 100, the checkbox to not be ticked when theres nothing in there, and for it not to be ticked when the value is < 1 and > 100. Figured a case statement would be the easiest. (this piece of code is just a validation check, basically in the real thing the user would have to enter in a value between 1 and a given number, and need to tell the user if that value is valid).
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
Select Case TextBox1.Text
Case Is = ""
[code]....
But what happens is, if I enter in the value 1 in the textbox, the checkbox becomes ticked, as it should. It tick with any values between 2 and 99 (any number not starting with 1) but the checkbox becomes ticked again when the value is 100. For any other range, say 1 to 70, the checkbox would be ticked if the value in the textbox is 1 to 7, or any number starting with 1 or 7, but not 8 or 9, or any number starting with 8 or 9.

I've already found evidence of another having this problem. You can see this on this post by someone else:
http:groups.google...096b3fcaa?pli=1
The problem is that when one navigates the combobox via the keyboard, the combobox's information doesn't update. If you click a value with your mouse, though, everything works wonderfully. The link I've mentioned suggests changing the binding from the Text property to the SelectedItem property. I'm very deep into this project and it would be a bit of a nuisance to change the setup so as to allow it to be bound to the SelectedItem property.What I'm wondering is whether or not I can detect the user changing the selected entry in the combobox and tell VB that they "clicked" the value, if that makes any sense.

In my MDI Application code I have a form that launches a second form then hides itself until the spawned form closes. It works great unless I choose to close the application while the spawned form is still up.
The following is some example code.
Dim ChildForm as New frmTaskWindow With { .MDIParent = Me, .AddingNew = True }
ChildForm.Show
Me.Hide()
[Code].....
Me.Show() ' error occurs here because my form is already closed by the system. Is there a way to get around this without just an error catcher?
