Selected Text Replaces First Line Of Combobox
Sep 4, 2011
I have a combo box that lists Customers:
Customers
ABC001
ABC002
ABC003
If I select ABC003 from the Combo box drop down it replaces the first line of Combo box text with that text. i:e ABC001 is now ABC003.
So if a user selects a customer and then changes their mind to say ABC001. ABC001 is no longer available.
How can I set the Combo Box from updating with the selected values?

I have a combobox with whose contents get populated via code. Works ok. But When I select something in the list and hit 'OK' it always returns as: nothing, "", or -1 (tried with .selectedValue, .SelectedText, and .SelectedIndex respectively)
Question is, How do you access the text in a ComboBox's selected Value??

In my VB.net solution I have a form in which I have to choose a beginstation and an endstation. I have to select both from comboboxes. Now what I want is that when I choose a beginstation, the chosen station will be gone in the combobox of the endstation so that I can't pick the same endstation as the beginstation.Is there a way to do this? I've tried a lot with SQL and LINQ queries but it didn't work out :(

I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.

Ok so here's my problem. I am trying to make it so when you push a button it will add a new character to my listbox. Everytime I go to add a new character its data replaces the existing ones I have already added to the list. I know what's doing it because it's using ThisNewCharacter everytime the button is pushed, I do not know how to work around it tho! I want it so it will continue to add new characters to the list when the button is clicked that doesn't replace the other characters data.

Consider the below code (which dynamically creates a dynamic SQL string) Is there a way to further compact string.join, so it does replace("'","''") on all array members automagically ? (without writing a custom version)

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

I am working with an ArrayList of ArrayLists. Every time I add a new ArrayList to the main AL, it replaces all previously added ALs with the new one.Here's an example
Dim al As New ArrayList
Dim al2 As New ArrayList
Dim list() As String = {"one", "two", "three"}
[code].....
I would expect the Final line should be "Final: one, two, three" but that is not the case. And if I pause and check my ArrayList (al), it shows 3 items, that all have "three" in every spot which is what the last AL I added looked like.

I have a problem keeping a selected value in a combox. I select a row in a datagrid and load another form, based on this selection the form and combobox is prefilled with data. When I close this form it sets the selected value on the combobox back to 0 and gives me an error 'There is no row at position 0', how can I maintain the initial selected value to work around this error

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

I have two comboBoxes: cB1 and cB2. Depending on the values I have selected in both comboBoxes, another value puts in a third comboBox called cB3. But if the combination of selected values between cb1 and cb2 don`t give any value in the third combo, first of all It has to appear a MsgBox advicing to the user of this situation, and secondly, I want that the execution thread of the application could be pause /stopped for the user could choose any value selected manually of cB3.
This last action is the problem because I am not able to stop/pause the execution until the user can select the value, and the code after this point is executed and gives me a Nullreference error.

I am having a problem with using a value from a selected item in combo box. While debugging using breakpoints I can see that the combo box is working fine. The problem is I need use the selected value of the text box in HeatTransmissionCoefficientforAsinglePipeCalculation function and while debugging I saw that ThermalResistanceofTheInsulation, ThermalResistanceOfTheCarrierPipe, ThermalResistanceofTheJacketPipe all have a value of 0 when this is not the case...
This is what happens when use clicks ok:
Public Sub btnOk_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOk.Click
' 1. Check if Metric or Imperial Units are selected.
' 2. Convert Entered Variables to opposite unit.
' 3. Determine what type of pipe is selected.
' 4. Determine what type of casing is selected.

I need a simple program that makes sure that the LINE IN is the selected input for recording. I can handle the program itself, I just can't find how to check the selected input at any given time. Note that I shouldn't interfere with any running program.
