VS 2008 Inserting A String Of Text At A Certain Position?
Sep 8, 2009
far it works! But it work's too well. What I'm trying to do is insert a string of text at a certain index position of a text file, underneath a certain line of text. So far I have:
'Controls Var 16
If CheckBox1.Checked = True Then
If Mytempstring.Contains("zrandomtextz=0") = True Then
Mytempstring = Mytempstring.Replace("zrandomtextz=0", "zrandomtextz=1")
ElseIf Mytempstring.Contains("zrandomtextz=") = False Then
[Code]...
It's inserting the text, but it's inserting it at every line of text in the file. So instead of one instance of "zrandomtextz" underneath "xinserttextx" I get "zrandomtextz" before every single line in the file. Can someone please help me as this has been an issue for months now? Edit: There are quite a few lines above this one, as in 50-150, so I removed all of the above section, however I can assure you that whenever it is simply replacing then writing to file it works flawlessly, it's only now that I'm having problems and this is when I try to insert new stuff under stuff.

I am trying to work out how I can insert the string "End" into my textbox at a specific cursor point?
(where the '???' is in the code below)As you can see by the code below this will happen when the user clicks return on the keyboard within the textbox.
I have the code to get the cursor index which is being stored as integer 'intcurrentcolumn'. Private Sub Enter_Click(ByVal Sender As System.Object, ByVal k As System.Windows.Forms.KeyEventArgs)

I'm outputting a number of variables to a text file and each field needs to be in a specific place.For example:I have a string that is varying in length, but will never be more than 5 characters. The string has to end on the 8th character of the line. Is there a way to write the string to ensure that the string ends at a specific place on the line, regardless of the length?

I am creating a function to insert a node at specific position, I am not sure about the criteria but may be in the mid.
how can I insert node in specific position. I am using XMLnode.appendChild method for insertion Do I need to rearrange/sort nodes after insertion. How can I determine what is structure and how should I find where the new node should be added according to current document structure.

My aim is to insert commands in to a console such as command prompt (except it isn't command prompt its actually a console engine for a game) and the commands will have shortcut buttons aswell which I can do my self, not a problem. My actual problem how ever is that I dont know how my vb form would recognise the process it needs to type in and how it would even find the text box to auto type the pre configured commands which I would have configured inside my form.

I have a RTB that I am generating during runtime. The users who will be using this app, need to be able to select unique IDs from a ComboBox and when they are selected, their value gets added to the RTB. Its ID is directly related to the their index in the combobox.
[Code]...
The problem, is that since the RTB is created during runtime, I won't know its created name. At anytime, there could be 10 RTBs inside of its own tab within a TabControls.So, anyone know how I can access the RTB without knowing its name?

I am working in VB 2008 and I have a textbox on a form that is used to enter a parcel number. I can enter the number in a 15 character string such as 12345678...... and it works just fine. The parcel number in real life contains dashes to make it easier to read, decipher, etc. so it looks like 12-3-45-67....... Under the textchanged subroutine for the textbox I have a case statement set up that checks the length of the parcel number as it is entered and inserts the dash accordingly.

so say I have a string called Cmd, and the text inside the string is Restarting server in ()..., what I was wondering was how I would go about inserting different substrings like 3, 2 and 1 in between the two parentheses? I know about Cmd.Insert() but I don't know how I would make it go between the two parentheses.

VB.Net (2008) doesn't seem to allow inserting formating characters (eg.) in String.Format:
'BAD MessageBox.Show(String.Format("{0}{tab}{1}", "Foo", "Bar"))
'BAD MessageBox.Show(String.Format("{0} {1}", "Foo", "Bar"))
MessageBox.Show(String.Format("{0}" & vbTab & "{1}", "Foo", "Bar"))
Is there an easier way to build a formated string that must contain formating characters?

Basically i have a query string that when i hardcode in the catalogue value its fine. when I try adding it via a variable it just doesn't pick it up.This works:
Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=WaspTrackAsset_NROI;User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';")
This doesn't:
Public Sub GetWASPAcr()
connection.Open()
Dim dt As New DataTable()
Dim username As String = HttpContext.Current.User.Identity.Name
[code]....
When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI"

I have a string like this: mstring = "0123456789ABCDEF"
how can I get the vale at a given position, such as 12?
I know with PHP I can do this:
val = mstring{12}
and it will give me the twelfth value in the string, which would be "C"

I have a couple of textfields in a Windows form. One of these textfields is allowed to be NULL. When I enter a value for every field, it is all inserted, no problem. When I leave the field (txtGewicht) blank, I can't seem to be able to insert NULL in Access Database.
If Double.TryParse(txtGewicht.Text, 0) Then
klant.Gewicht = Double.Parse(txtGewicht.Text)
Else
[Code]....
This is what I get:
"Cannot set column 'Gewicht' to NULL, please use DBNull instead"
So I changed 'Nothing' to DBNull.value, but it then tells me that System.DBNull cannot be converted to type Double.

I am struggling to find a solution in string manipulation - I am trying to extract a certain part of the string element after the '=' character - say for ex. dim s as string = "/mysite/secondary.aspx?id=1005"
I am trying to get the string after the "=" and just to grab the 1005. I tried indexof and split, but i am not sure where i am going wrong.
