I have an app that writes to XML. If a text box is filled, then I write that value to the XML doc.
writer.WriteStartElement("VEHICLE_LICENSE_NUMBER") '10-28 writer.WriteString(frmCitation.txtPlate.Text.ToString)
writer.WriteEndElement()
[Code]...
what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.
full code here
-------------
Dim objReader As New System.IO.StreamReader(sOpenFile.Text)
Dim sTextLine As New ArrayList()
Dim sText As String = ""
Dim i As Integer = 0

I'm trying to write a simple datagridview to excel. (I know there are lots out there but I can't find this one tweak)The following code runs well enough, I just need to be able to run a loop that says if a given row in the datagridview is .visible = false than I need the corresponding row in the excel spread sheet to become hidden.[code]
View 5 RepliesI have a datagridview and once I populate the view with the data source I hide the columns that I do not need. For some reason the 1st column is not hiding. I have checked the column name and they match and the 2nd line executes fine hides the column for the EVENTID. I even did a messagebox.show( dgvTourOther.Columns("OTHERID").name) and it returned the correct name.
dgvTourOther.Columns("OTHERID").Visible = False
dgvTourOther.Columns("EVENTID").Visible = False
The values being passed are all strings. I do this on 3 other datagridviews ok but for somereason this gridview is acting different. I am going to try an rearrange the columns and see if that helps.

Say I have Combobox1 with items (1)Breakfast (2) Lunch (3)Dinner
and I have combobox2 with items (1)Apples (2)Bananas (3)Grapes(4)Oranges
Now when I choose Breakfast in combobox1, I want user to see all 4 items in combobox2. But when I choose Lunch in combobox1, I only want user to see (1)Bananas(2)Grapes(4)Oranges in combobox2, hiding Apples.
Does anyone know a code where I can hide an item in a combo box depending on the condition?

p.StartInfo.FileName = "cmd.exe"

I am stuck on hiding a column in listview. I want to hide the items in that column as well. I tried setting the width to 0 but the user can still size it out and see it. I heard there was a way of doing it by removing the column completely and all of its items and then they can be refreshed back into that column when need be.

If you start an exe file by using a Process, you can set certain ProcessStartInfo parameters beforehand, such as CreateNoWindow = True (to hide the process), as in this example:
Dim myExe As New Process
Dim p As New System.Diagnostics.ProcessStartInfo
p.FileName = "cmd.exe" 'starts the cmd console

Im learning VB.NET and as a first task im creating a login form. ive been trying to link it to another form once a correct username and password are entered. however, despite that i still cant be able to hide it or unload it once the next form is loaded
Here is the Code

I want my panels to be visible when the radio button is check and when its unchecked it would hide.
Setup:
5 panels
5 radio button
radio button1 shows panel1 if checked Each radio button is set to show each panel and hide each one if its checked or not. Ex:
Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged
If RadioButton1.Checked = True Then
Panel1.Visible = True
[code].....
When my form loads it shows panel1 because radiobutton one is check. But when i select another radio button panel one doesnt hide. Also when i did it to the other panels such as 2,3,4,5 it does hide and show when the checked state has changed.
When my login screen loads, if the user has not created an account the form will close and a form to create an account will appear. However when I code this both forms stay visible, instead of just the one. Where am I going wrong?[code...]

It seems like such a simple thing to me, but it seems like the usual, me.hide() isn't working in this case. I have 2 forms that tie together, the login form, and then the main for being form1.

View 1 RepliesI have a log in form, and once you log in, it's supposed to show a new form.
The problem here is...if I use Me.Close(), then both of the forms close, and the application terminates.
If I use Me.Hide(), than the first form doesn't actually stop running in the memory, and proceeds to run in the background even after you're done with the program.
