PerformClick() Doesn't Work - How To Make It Work

Feb 2, 2011

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:

btnWhatever.PerformClick()

Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

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 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.

Script Doesn't Properly Close Word, And It Still Remains Open?

Nov 20, 2011

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

Databound Combobox Doesn't Update Properly Depending On Input Meth

Feb 10, 2011

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.

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.

BackgroundWorker IsBusy Property Seems To Not Work Properly?

Dec 2, 2009

I'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, 2009

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.

How To Make A Windows Service Work Properly

Aug 3, 2010

My 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

VB 2008 Memory Leak - The Graphic Doesn't Dispose Properly And Garbage Collector Gets It?

Jul 7, 2011

I have prided myself in having a pretty clean code however in the game I am making I have a player view (showscreen) and a host view, which is a copy of the player view (on a smaller screen). This way the host can see what's going on.The problem is that the graphic doesn't dispose properly and Garbage Collector gets it, though I have noticed it will crash if GC doesn't get it in time. The larger the showscreen window the more junk gets put into memory, which sucks.I thought I had everything correctly disposed below but still doesn't get the job done.

What Data Type Will Allow The User To Input 0 And Allow The Mathematical Functions To Work Properly

I am currently using double data types. The problem I am encountering is that sometimes the user will have to input a value of 0 in the required text box and this creates an error. My question is what data type will allow the user to input 0 and allow the mathematical functions to work properly. Decimals maybe?
