I was wondering if anyone had any resources on vb controls, I'm just a beginner so please excuse my little knowledge. I have been having troubles with the checked listbox control, selectedindex is the method for displaying the checked list position yeah? so what is the method that i need to use the actual vaue that is stored in the checked listbox ( the string ) ?
View 2 RepliesI have downloaded and played with the standard MS Examples in the VS2008 Download pages.They are very good for some areas but a little light in database handling.
1) Search Grid plus the Record Selected Display (this is beyond the scope of MIcrosofts VS2008 Examples)
2) Using plain ADO commands with VS2008 (rather than all the fancy data controls)
3) Using Stored Procedures rather than all the fancy data controls
4) Database Access Examples
My application area of interest is mainly ERP, Accounting and CRM Systems
I have a bound listbox, I want to pass selected items to another listbox. Any recommendations or documentation?
can I use the collected selection as datasource and specify the id name somehow?
I've got a checked listbox on my form which saves the checked items to a spot in my database on the .ItemCheck event.But there's a problem, when I begin checking items, I check the box and click off it, but it doesn't save. (This is if I've only chosen one item)
If I choose two or more items it will save, but unchecking them takes a lot of clicking around to figure it out.Is there a better event that I can use? I've tried the SelectedIndexChanged and that has the same result, there's a lot of clicking around in the checkboxes to end up with the desired selected items, and it does not allow a single item.
I have a program that autologs itself into facebook and monitors posts to my main page and tells me if anything new comes up. Every minute my program refreshes the page and searches for a new post, if my session is expired it logs itselft back in automatically. If I'm in explorer trying to play farmville and my facebook monitor program is running then I'm forced to log in about every minute because my login at the browser kills my vb.net program session.
Then my vb.net program logs itself back in and I'm out! This behavior doesn't happen If I have two browsers running I can log into both and it doesn't seem to effect the other. I can even have my wife log in from another machine while I'm logged in and It's ok. So The question is why is useing the webbrowser controls in the Vb program any different then just having 2 open and logged in browsers and jumping between the two.
Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.

View 2 RepliesThe thing is im making formless application, thats visible in tray only.. But i have like 21 icons for default functions.. and when my program launches all icons with the exe file is loaded in RAM. Is there a way to use an external resources file, where all the icons is stored, so when application needs one it takes it from rscx file and loads it, and when it needs other icon it releases the one taken and takes other.. Im asking this not just for ico files, but for any file types that can be stored in my.resources..
View 3 RepliesI am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
View 5 RepliesAs i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.
I am looping through all controls on my form and for all checkboxes, I want to see if they are checked. I cannot get the Checked property when doing this. Am I doing something wrong?

I'm having some trouble trying to inherit a control that uses an embedded resource. The trouble is - this control uses me.GetType() instead of GetType(ControlName). Now when I try to use the derived control, it looks for the resources in the derived control's assembly, instead of the base control assembly, and obviously - doesn't find them.

View 2 RepliesI am reading information on missed deadlines from a database. For each missed deadline I add a item to the checked listbox and store the deadline's information in an array. I now want to disiplay all the selected (in the checkedlistbox) deadlines' information in another control, but at the moment I am getting an error. This is the code I am currently using to check which items have been selected
Dim x as integer
For x = o to array.count - 1 do
If checkedlistbox.GetItemChecked(x) = true do
'Here I am displaying array.item(x)'s information in the other control
end if
next
1) Say I have five items in the checked list box and I select all five items, when it gets to x= 3 it gives me the following error "ARGUMENT OUT OF RANGE EXCEPTION was unhandled: InvalidArgument=Value of '3' is not valid for 'index'. Parameter name: index"
2) Say I have five items in the checked list box and I select ONLY the first two items, when it gets to x=4 it gives me the same error as above only for the number 4.
I have tried the methods/functions GetItemCheckedState, SelectedIndices and GetSelected as well, but they all give the same or similar errors. According to me the index cannot be out of range as I have five items in the checkedlistbox as well as the array.

View 4 RepliesShould: take items and fill checked list box with possible tours that the company can receive (this is done and working) i.e. for 2012, Titleist gets X, Y, and Z; so there are two checked listboxes for 2012: lvl 1 and lvl 2, username specific Both have lists "X, Y, Z" in that order, lvl 1 and 2 is for the permissions level, 1 is lvl 1 and 2 is alex's 0 marking for full details code goes through and checks if lvl 1 is marked, if so it checks the tour in the lvl1 check box if zero is marked, finds the tour in lvl 2 and lvl 1 and checks both items if a tour exists for company but not for the user, the checkbox exists but neither is checked

I am wondering if there is a way to get the keys from the registry and display them in a checked listbox. For example I want to get all the keys and there values from "HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun". This will allow me to see all the startup items. Is there a way that I can get all the values and display them in a checked listbox. I tried using the GetValue but it seems that you have to set the key that you want.

View 1 RepliesI am trying to display multiple check items from a listbox into a label seperated by a comma. Everything is working fine but the only problem is that when i check first item in the listbox nothing happens and when i check the second item then the label shows the first item. Then when i click third item the label shows the first and the second item and so on. When i uncheck the item it does the same
My question is why it does not show the items in the label as they are selected.

I am sure that it is very easy but I could not manage it. my aim is to choose some items from a listbox and a picturebox will display the photo in resources with the same name of the item in list box. here is the code I wrote but I cannot make it work.PictureBox1.Image = My.Resources.Resource1.ListBox1.SelectedItem
it gives a mistake telling that listbox1 is not a member of Resource1. I know this; but the result of Listbox1.selected item is a member of resource1...

is there a way to validate controls on a form, where the validation rules themselves are stored in a database table?My problem is my application is used to submit forms to mulitple government agenices both local and state level. Every entity seems to have there own rules about what needs to be in what location. i would like to not have to code all of the various rules for all the different fields. My thought was to store them in a database table and then perform validation based on rule table lookups...however I would like to use the .NET validation controls.

Then skips straight to the Else without performing the two lines in between, regardless of whether the item was checked or not checked. It doesn't crash, doesn't throw any errors, so I am assuming I coded this wrong somehow.
I's there a way that I can access the properties of all controls stored into my array of object using LINQ.
Public Sub DisAble(Byval ParamArray ctrlCollection() As Object)End Sub That is my sub routine where im trying to reset all controls that will stored into that object of array. But im trying to attain that using LINQ so I wont use any loops to access all of it.
