ProgressPercentage Does Not Seem To Work Properly
Nov 9, 2008I am using a backgroundworker to start ffmpeg and trying to use a progressbar.ProgressBar1.Value = e.ProgressPercentage does not seem to work probably because the way ffmpeg uses standard error to report progress. I think i could use the output text to do the trick. the output.Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 29.92 (359/12) [code]

Ctype Doesn't Work Properly?
Oct 31, 2009i've got a problem here whereby my ctype doesn't work.firstly, to replicate my case briefly, i've created an extension of control class
[code]...
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?
BackgroundWorker IsBusy Property Seems To Not Work Properly?
Dec 2, 2009I'm using the IsBusy property to determine when a backgroundworker has completed. In the RunWorkerCompleted event I assing the result of the RunWorkerCompletedEventArgs to a public variable within the module where the backgroundworker events reside. The trouble is, the IsBusy property occasionally becomes true before the public variable gets assigned the value of the RunWorkerCompletedEventArgs. I experimented with putting a Threading.Thread.Sleep(10) after the IsBusy property becomes true and it seems to fix the problem. But it really doesn't seem right that I should have to do this. What is wrong here? I have placed the backgroundworker events in a component that is instantiated from the windows form, instead of placing the background worker events within the code of the form itself.
Here is my code;
Function SendAndWait(ByVal IntegerArray() As Integer) As String
Component.BackgroundWorker.CancelAsync()
Do While Component.BackgroundWorker.IsBusy

Can't Get Select Case Statement To Work Properly
Aug 19, 2009I'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.
Columnorder Saving Class Does Not Work Properly?
Feb 23, 2012I found a class that saves column order and column width for a list view but i cant get it to work properly.
Public Class cListviewHelper

It saves the right number of columns but not in the order they are.It always saves them like this in the registry "0,1,2,3,4,5,6"
How To Make A Windows Service Work Properly
Aug 3, 2010My project requires that a windows service checks up a table on a sql database(MDF) and if product existence is 0 then sends an email to some mail address and keep checking every 24 hrs.Now Im able to send mail messages but what Im not able is to make the service itself to work or at least make sure that is working.I do the following(correct me if I do something wrong or missing a step):
1. create a new project and choose windows service
2. add a timer and set to 4000 ms just to test not wait the 24 hrs lol
3. then open its event timer_elapsed and put some code on it, like a msgbox that would keep spamming every 4 secs just to test
4. at the event onstart I enable the timer by: timer1.enabled=true
5. at the event onstop I disable the timer by: timer1.enabled=false
6. right click then choose add installer
7. in the newer installed with the two objects:
a. serviceinstaller1 set its properties to: displayname: myservice and servicename: myservice
b. serviceprocessinstaller1 set account property to LocalSystem
8. build the project and install it by opening the VS console and type: "installutil c:path blah blahservice.exe" then hit enter
9. all successfull installed open the pc manager and run the service from the list and this should be the deal
Now my real problem is that by following those steps my service is sucessfully builded, installed, and started but after the 4 seconds no msg pops up so this leads me to think that is not doing anything or I did something wrong in the steps above. Is there another way to test if this service is working else than the msgbox or the log entry? Plus, Im working on my home pc which is a xp OS. I tried the same at college pcs wich are win7 and when I did install by the console it returned an error weird but in my home pc it doesnt(and I have to present my project at college at college and tomorrow

View 8 RepliesVS 2008 : Work Properly With The Reflection To Create A Module/plugin-based Application?
Sep 24, 2009I have found a lot of articles about Reflection and know how to create a class. I'm practicing how to work properly with the reflection to create a module/plugin-based application.So I found a simple example which is working great, but it isn't dynamic enough, 'cause it is hard-coded. I need to read all the .dll's from the application.startuppath & "modules" & *.dll and get there names (without the .dll).Code is was testing for practice returns the form (I know that this is not the correct way to call the dll dynamically):

.net - Not Checking For Control Key Pressed Properly?
Apr 5, 2011I got this timer tick function: Private Sub controlTick(ByVal sender As Object, ByVal e As EventArgs) Label2.Text = (Control.ModifierKeys = Keys.Control) End Sub
That is supposed to make my label say "True" if I am currently holding down the Control key, and "False" if I am not.But, how come my label is always "False"? What is interesting is that if I press the Control key at lighting speed a bunch of times I can see for a fraction of a second "True", but immediately turns to "False".
Timer ticks every 50ms.
VS 2010 : Control The Looks Of The Button Properly?
