I have a Main form, called Main.vb, that is a Parent Form. I have another form called Notes.vb. Inside Main.vb I have a toolstrip with a button on it called Notes. I'm wanting to change the checked status of the Button to either True when the Notes.vb window is open inside the parent or to false when it is close. Is this possible?
View 6 RepliesI'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.
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.

I 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 RepliesI added a setting in my.settings, the setting is a listbox, and I know you can put controls in a listbox, but for some reason it will not let me add a toolstripmenuitem to the listbox in my settings. Is there a fix to this?
View 5 RepliesI really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:-
m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.
I was wondering if there was any tut on how to aan item to a checked listbox thats already populated?
I thought of making a button and a text box .and when u push the button it add whats ever in the text box to the checklist box .

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.
Is it possible to count how many checked items there are in checkedlistbox and then display that number in a textbox?
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.

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.

project im working on for my course,the idea is a photo printing machine that loads up 4 images if usb stick is checked and a different 4 if memory card is checked. and then whatever image is selected appears in the big picturebox on the left [URL] i have 2 print size options set as radiobuttons, radiobutton 1 = 6x4, which costs 25cent per photo, radiobutton 2 = 8x10, and is 50cent per photo.i also have a textbox which will display the number of copies to be printed So here's my dilemma, when the print button is selected alongside one of the radiobuttons i want it to display a message saying something like this "you have selected (whatever the amount of copies)of this photo sized 6x4, or 8x10 depending on which radiobutton is selected, and i want it to display the total cost which is the number of copies multiplied by the rate for the print size selected, then an option saying "Do you wish to proceed" Yes or No.
