.Net 2010 - Get File System Watchers Working Properly?
Mar 2, 2012
I'm having issues trying to get file system watchers working properly, I'm not sure whats not right here, I want to use multiple, but I can't even get one of them to fire on an event... simple form with a listbox for folders to watch and a listbox to list changes detected and a command button to launch watchers.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
lstFolders.Items.Add("C: emp1")
lstFolders.Items.Add("C: emp2")

I am coding myself a Visual Basic.Net 2005 Slot Machine program. I've been hard at work on this for about a week and half now. From what I have with it it works and all. However there are so many annoying errors with the program.
LIST: - I am not winning when I should be. My winning conditions is set when you get 3 of the same picture you are to be awarded with some credits. It works but sometimes when it does land on 3 of the same pictures it still says that I've lost. This is the main problem and I am about to pull my hair out about this - The image with the lowest value is showing up the least and the picture with the most value is showing up more frequent? I don't want to change them around to fix that.

In my word processor I have an 'Open' option on a menu strip. Here is the code for it:
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click
With ofdFile
.Title = "Select a file to open"[code]....
For some reason when I press the 'Open' item and open the ofdFile dialog box .txt files do not appear even when I have the 'Text Files' filter selected However, when I use the 'All Files' filter they appear. And the 'HTML Files filter is also working properly.Why are the .txt files not appearing when I use the Text Files filter?

I don't even know where to begin describing this. I have a project, that uses settings, for some paths, settings that I retrieve with the My.Settings. function.In my laptop, when I change the .exe.config file, the settings are updated accordingly, but when I try that on the production server, it just shows the default value used while compiling.
I tried changing the solution configurations to debug and other custom configs with no effect.Tried to use the same folder copied and pasted without version control, still the same result.Tried a co-workers laptop, by using the last svn revision, it works there too. But on neither of the servers works.

I cannot figure out why my calculation is not working. I am doing for 1 to 12 and it gives me 12 inputs but counts my entries as 13? What am I missing. If I change it to 0 to 11 same thing. I am not sure what the issue is, but I cannot see it, and am not sure where to look.I need to end up with 12 cycles through and intEntries to be 12.

I have an unbound checkbox in my datagrid view along with other bound fields from a dataset. I do not need to send back the checkbox status to my dataset or the DB. Instead I will loop though the DGV and look for those checked and do another process with them after its done being loaded. The problem is this. When I check a checkbox, then check another, the first one goes back to unchecked and so forth, back and forth. There is no add, update or deletes needed for this DGV.

i have a windows forms app which displays a bunch of records from my sql database. when i modify records in the grid and click on save, all changes are saved EXCEPT the changes made to the currently highlighted row. they aren't written out the database until i exit the actual program, despite clicking on my save button.so for example, if i change 5 different records in the grid, and click on save, and then click on refresh to reload the data from the database, 4 out of the 5 are saved correctly, but the row that is currently highlighted (meaning, the last row i changed) still has the old data.My code for the save button look like:

If you try to access a password protected page it does a security check and redirects you if you are not logged in, retaining the URL (ie. Members/MemberLogin.aspx?oc=/PodCast/Default.aspx)The vb script places the "/PodCast/Default.aspx" in a variable and holds it until the login process is complete.Once the user types in their username and password it is suppose to do a Response.Redirect(strRedirectURL) and go to the "/PodCast/Default.aspx" but instead it goes to the default.aspx page for logging in successfully

I am using Visual Basic Express 2010.
I have programmatically set up a Datagrid and binding navigator etc., but I cannot get the movenext, movelast buttons to actually hook up to the Data on the Datagrid.
I have tried to set up an addhandler for the BindingNavigatorMoveLastcontrol, and although I can get the BindingNavigatorMoveLastcontrol to display my messagebox
WHICH IT DISPLAYS TWICE FOR SOME REASON I cannot get it to actually move around the Dataset, or any of the other navigation properties for that matter.

I have spent a long time trying to find a solution for the problem I am having with comboboxes within a child form. I'm sure this must be a Microsoft error and not something I'm doing wrong..The best way to explain the problem would be to tell you what I have done so far:
If you open a new Project in VB and add two Windows Forms. Form1 will be the parent. Form2 will be the child.On Form1 add 1 x panel(Form2 will open up within the panel so make sure the panel is big enough to fit Form2) and 1 x button. The only code needed for this form is:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
Now run the program and click button1 to open form2 (form2 should now open within panel1).
The comboboxes and textboxes lose some of there functions for example:
1. You cant set focus on combobox without hitting drop-down
2. You cant highlight text properly in either the combobox or textbox.
3. You cant set the cursor index position using your mouse in the combobox or text box.
Does anyone know a way around this?? Mainly for the combobox as I've got some functions working for the textbox.

I am having issues with a combobox set to:
AutoCompleteMode = Append, AutoCompleteSource = ListItems.
Example: Items in the combo are: "Average", "Good", "Poor". If "Average" is selected in the combo, then I type "G", "Good" will autocomplete. But if "Average" is selected, tab out of the control, then tab back into the control, then I type "A" nothing is autocompleted. It just shows "A" in the combo.

I am trying to introduce "user.config" corruption handler in my application. The approach I am following is that when the first time my application access user setting variables, I put that in try catch block and if the file found corrupted i simple delete it and reload setting variables. but I dont know why reload functionality is not working properly. What my understanding about reload is that it will reload all user setting variables to its default value, but in my case even after reload() everytime appliction access user setting it generates exception. My code snippet is as follows:
Try
test = My.Settings.Mysetting
Catch ex As Configuration.ConfigurationException
