I've created one form with TextBox1, TextBox2, ComboBox1. Then when I click one of the ComboBox1 items I want to load the saved settings and display them in the TextBox1 and TextBox2. The settings are:
[Code]...
I am really baffled and can't work out why this is happening. I have this code with transfers text from a textbox and adds it to combox items. My problem is that after the combox has got 2 items init, anymore you add there will be muliple of them and not just one for example:

How to add each from file to comboboxe's item?
On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If
Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls
If box.Text = "7777" Then
box.Text = "Found"
End If
Next
How do i can make combobox list to be File names like:
[Combobox1]
- A.txt
- B.txt
- C.txt
I want Combobox list to be files from my webserver [URL] and i want it pickup them example if here is NERD.txt i want it pickup name NERD.txt from my webserver and include it for a one of the list items.
Why would this event only work once, the first time I select an item? If I select another item off the list nothing happens.

on Form1, i have a combobox1 where i have 15 values. im using a case statement with those 15 values to decide what is the next form to go to. i need to make sure the user cannot add in his own text to it or click the NEXT button without having any value at all. how do i add these "exceptions" to my code?
i would think any exception would go before the case so that it could tell you didnt put in the right answer before it looks through the case statment and give you a nullexceptionhandler reference.
How can i make the font's size in richtextbox equal to combobox1?
RichTextBox1.font.size = combobox1.text
not working
[Code]...
1. Add Combobox1 to a form and add the above code
2. Run the form
3. Enter some text not in the drop down list or leave the combobox text blank
4. Click the form close button ( the "X" )
5. The error will be displayed, "ERROR - Invalid Entry!"
6. Press OK on the messagebox
This is where something goes wrong. If you click the Dropdown arrow of the combobox, the dropdown list wont stay open. ( unless you hold the mouse button down ). This doesn't happen if you click or tab to another control (like a text box). Then after the messagebox is displayed the ComboBox still works fine.
I have a weird behavior with tabs on a VB.NET form.On a form I have several comboboxes, text boxes, and 2 buttons.I have made sure my tabindex are in the order I desire, meaning combobox1 has tabindex 1, combobox2 tabindex 2, button1 tabindex5,etc..Here is the behavior, when I first open the form, if I tab from combobox1 it jumps directly to the button, instead of combobox2, however once I help things with the mouse, it will tab in the appropriate order.

I want to learn how to populate a combobox so if a vlaue is selected in another combobox then it will be invisible for selection. You can NOT use combobox1.items.remove since my box is bound to a datasource.So I either need to create a new query and adapter and bind the combobox2 to that query, or fill combobox2 from combobox1 minus the selected item in combobox1. Either way I need some help writing code correctly.I have tried a few different ways but not succesful, I was probably on the right track a few times but I am still not very proficent in code writing.This is the code I have written so far for my program, I deleted all my attempts at remove selected item since none worked and were just confusing.

I have one table from where two comboboxes get their drop down lists, showing info that has been entered into the table (boxes are bound to the table columns I.E City (Box1) and Country (Box2). what I would like to do is if a city is selected in box1 then box2 will autofill with the country name.
View 3 RepliesIn my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2
I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also. For instance, on Row1, if comboBox1 = A, combox2 = B
Then on Row2, if comBox1 = Y, comboBox2 = Z
However, when I change Row1, Row2 is also changed to reflect what was chosen in Row1. Is there a way I can tailor it to each specific row?

But if the user hides a column in the datagridview, I want the textbox below to disappear as well and the other textboxes automatically take up the empty space.
I made some screenshots so you will be able to understand it better:
When the user hides the column:
The column named "Totaal prijs" has now gone and so has the corresponding textbox below. But the columns in the datagridview now stretch nicely to take up the free space. How can I do the same with the textboxes?
