I have a Query which looks like this (in Query builder VS11)[code]...

I need to display data from a complex sql query controlled by 2 combos. The sql main query part is working fine but I cannot get to link the combos to the query. On form load I load combo1 by means of a sub. Then with SelectedIndexChanged I load the combo2. Both combos load fine by do not intereact with eachothers meaning combo1 doen't filter out combo2's information.

View 13 RepliesI have an issue with my DO While loop (it has to be a DO While loop). It is supposed to loop until a value of -99999 is entered for the value of previousReadiing. The program works, and it will stop after -99999 is entered, but only after it goes through the rest of the loop.How do I get this to end rather than have to finish through the other input statements and calculating again?This is homework so I don't want the answer, but can I get a nudge in the right direction please?

View 9 RepliesI am having difficulties populating a checkedlistbox (CLB) based on the selection(s) made in another. It should also be noted that I have a "Select All" checkbox at the top that checks/unchecks all of the items in the first CLB. Here's the code:
[Code]...
The first CLB is populated with an arraylist of values on the button click event. Based on whatever is checked in the first CLB, corresponding values from an arraylist of structures should fill the second CLB.The following code partially works until the "Select All" checkbox is clicked at which point if other values have been selected before "Select All" is checked, the second CLB is filled with the correct number of corresponding values BUT only those of the most recently selected item of the first CLB instead of all of corresponding values of all of the items that were not already selected.

Trying to get a database into my Checkedlistbox. This is the code I have so far: Private Sub CheckDevices_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim connectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=N:DeviceList.accdb"
Dim str_DeviceList_Select As String = "SELECT * FROM DeviceList"
Dim myConnection As OleDbConnection
Dim myCommand As OleDbCommand
Dim myAdapter As OleDbDataAdapter
Dim myDataSet As DataSet
[Code]...
So I have the dataset with database in it, but I am struggling to get it from the dataset into the Checkedlistbox. Could someone do some quick code for this?Secondaly, I also want to set the checkbox's by using a string of integers which will look like "0110100110". If the value is a 1, I will want the corresponding checkbox to be checked, eg, "0110100110" So I would take that one, and check the 8th checkbox down in the checkedlistbox... So if anyone if feeling really generous, could use a little help with this as well.

I tried adding another clbFields.DisplayMember, but this obviously just overwrites the table name with the column name. I also tried doing:
clbFields.DisplayMember = "Table_Name" & "." & "Column_Name"
but that didn't work either.I know it's not exactly life threatening if the user can only see the column name, but it'd be nice to be able to see the table name in case of any duplications?

I have a few checkedlistboxes in my GUI and the items in them are changed as needed. For example if I check an item in checkedlistbox1, it would trigger the items fromcheckedlistbox2 to be removed and new items will be added to it that are relevant.Similarly, depending on when the items are checked inside the checkedlistbox2, it will trigger new items to be added to checkedlistbox3. So I have added the functionsSelectedIndexChange to handle when items are checked inside the boxes.
I am running into a problem however. For example, I have some items in the checkedlistbox2 and one of them is already checked. When I click on something else in checkedlistbox1 it clears out all the items and repopulates the checkedlistbox2. In that case, however, since something was previously checked in checkedlistbox2, the selectedindexchange event is also triggered for that one as well because something was changed in that. Can I disable this somehow because technically I didn't "check" or "uncheck" anything, all I did was remove a checked item? I tried doing something like adding an if statement inside the
Ive got a CheckedListBox where I have a list of devices and a checkbox to tell me whether they are on or off.

View 1 RepliesI just can't seem to get this right, what I'm trying to do is use FindWindow to find the windows of more than one window. Here is the code:
app_hwnd = FindWindow(vbNullString, CheckedListBox.CheckedItems)The thing is, if I use .SelectedItem, it only finds one window and if i use CheckedItems/SelectedItems it gives me an error: "Value of type 'System.Windows.Forms.ListBox.SelectedObjectCollection' cannot be converted to 'String'."
So right now, I'm confined to using FindWindow for only one window--when I want to do it for more than one window.
