Combobox Bug - Text Typed In Combobox Appears In Another Control (textbox) On The Form?
Feb 20, 2012
I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.

I had added the items
1
2
3 to the combobox.
Then I gave the "Select" to the text of the combobox.
How can I able to reset combobox to select the text("Select").
I had tried by giving -1 to the SelectedIndex. But it gives only Empty.

Brand new to VB 2008 Express, but have done some work in VB 6. Not sure what I'm missing, but here goes. I have two comboboxes linked to an Access 2007 database. One box lists the names of the States in the US.
This is what I used for the Table Adapter Configuration Wizard for the combobox "State" SELECT ST_UID, ST_NAME FROM STATE
For the combobox County I used: SELECT ST_UID, CTY_NAME FROM COUNTY ST_UID is an Integer.
I created a label with a bound value to STATE.ST_UID so that when a user selects the name of a state from the State box the appropriate ST_UID populates the label, (i.e, California has an ST_UID = 5).
The problem is when a state is selected, I only want the Counties for that state to appear in the County box, i.e, COUNTY.ST_UID = 5 if California is the selected state.
I then tried to convert the value in the st_uid label to an integer:
CODE:
This is what I last tried when again using the Table Adapter Configuration Wizard for the table that populates the County box: SELECT ST_UID, CNTY_NAME FROM COUNTY Where ST_UID = 'StUID' Order By st_uid, cnty_name
What I'm getting is a "Data type mismatch in criteria expression." I'm sure my error is something so simple.

I am designing a form to Enter new City Name list where i accept following fields
CityName, District, State, Country, Pin.
because a State names and Country names can be retrived from earlier entries, i want to allow user to select desired name from a list in combo box or a list in Auto Complete Custom Source for text box, to do this i have added a Table Adapter to underlying DataSet having Query "SELECT DISTICT STATE FROM CITY ORDER BY STATE".
Now, how do i use this Table Adapter to fill the ComboBox List without binding
And also Custom Source List for TextBox.

Again a little (for me) tricky thing:Supose you have a ComboBox control with predefined values - to keep it simple, let's add some colors:
- Blue
- Green
- Red
- Yellow
Now you have a TextBox control as well. If you type into the TextBox BLUE (non-key sensitive) I would like to make it recognize that this value already exists. It does not have to do anything else except for notifying me about a match.I do think that the TextBox1.KeyPress or TextBox1.TextChanged event is what I need but I have no idea how to compare to the ComboBox1 items. I've tried to create an Array of my ComboBox1.Items but didn't get much more than errors. Can anybody help? I am sure it is quite simple however, I can't get my mind set to go in the right direction

What I to do is really simple. I want to add a group of text boxes in my VB net application. note that the number of text box only can be known at run time.
I want to give default value to this group of text boxes. At run time, users can input text and change the text for each item.
How can I do this? Is there a control to do this?
What I can remember is ComboBox control. However, I only can display the item text and do not know how to change the text for each item.

I have a completely basic program here that I want to simply take text from a textbox and the selection from a combobox, and then run the following:
CODE:
Obviously WKID and PROCESS are the variables it will be pulling from the data that was put in by the user. That code was just in a simple batch file that I made with 2 variables. I am wanting to pull those 2 variables in when clicking the "kill process" button, it will run a command simliar to the above and end a process on a remote networked computer.
