How would I go about finding a string of text in a text file then underneath that string of text inserting my own string? So far I have this which isn't working:
Dim MyFile() As String = System.IO.File.ReadAllLines(filePath)
Dim MySW As New System.IO.StreamWriter(filePath, False)
Dim Mytempstring As String
Dim StoreInd As String
[Code] .....
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'm having a problem with making the Picturebox Transparent to the a Image layered underneath I'm getting tranparent to the form background color. Is there a Visual Basic Code Solution to achieve these properties? I used the imagebox in Visual Basic 6 and had no problem with this.

View 2 RepliesCurrently I have a listbox on a VB 2010 project and I have hooked a ContextMenuStrip to it. Everything works from here but what I want it to do is select the item underneath the mouse when i right click. This would make it so i wouldn't have to left click the item then right click to get to the menu.
View 5 RepliesAny way to remove this problem I have in VB2010. I've done a picture box, where you can draw lines by clicking with your mouse. There is a label running along with the mouse pointer, but every time the cursor moves over the line, the label removes the line under it. I've tried setting transparent background to the label.

The XML String I am getting from other application is converting & to & and 0F to ?F etc. I am loading the XML string into XDocument and inserting into db using linq. Is there any easy way to replace those characters with actual ones.
View 1 RepliesVB.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"))

View 2 RepliesBasically 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

When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI"

View 3 RepliesI 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'm trying to do some simple XML manipulation by searching one XML file for a set of nodes and inserting them into another XML file at a specific location.I'm able to succesfully create a node list from one of the files using the following xpath statement [code].....
I'm struggling to see how I can easily select any node I want within the first XML file but the second file refuses to play ball! I've attached the second XML file should anyone wish to check that I've interpreted the structure correctly.
Im brand new to programming. Apart from doing a few digital dashboards in excel i have zero experience with vb or creating code. You may need to be patient.What i am trying to do is from my form, browse to a pic in a folder and insert it into a picture box in the program. the pic should insert itself into the program after it has been selected, and the picture should resize itself to fit the pic box (or viceversa if need be)
I have looked at some similar threads on this issue but none of the code in those solutions is working for me.
I've been using VB.NET for a few years now, but I never really got into binary files. How do you add onto binary files from the beginning? Here is some example code:

writer.Write("HELLO WORLD!")

Is there an easy way to insert a line into the very beginning of a large file?I want to insert an XML header line into XML files that my program processes (These files can be very large, so reading it via bitstream and writing it out is not a good option).
File.AppendText makes it very easy to append lines to the end of a file, but I don't see anything for inserting text.I wonder how does say Access work in processing say a 50 meg access database file? There must be a similar process where you can insert data anywhere inside a large file.
I have a parent window which has a ListView that is bound to an ObservableCollection that gets it's data from an XML file. On the parent window, I have an add button that opens a opens a Modal Window (form2.ShowDialog(), I think this is a Modal window).
In the child window I have a few text fields and an add button, the user enters data for a new record and clicks the Add button and the XML file is updated with the new record.
What I am seeking to do is when the child window is closed that the ListView in the parent window is refreshed to show the new record.
When I am updating the XML file from the child window, I am doing this directly to the XML file, should I be adding the data to the file in some other manner which would raise an event on the ObservableCollection?
I was heading down the path of adding an event handler to the add button on the parent window and attempt to force a re-read of the XML file, but I cannot figure out how to achieve this, below is what I have done so far.
form1.xaml.vb:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click
Dim frm As New newEmergencyContact
[Code]....
I cannot workout what should go into the refresh_EmContacts sub, do I need to call some kind of ObservableCollection event handler to notify it that it has been updated and to do the re-read?
I'm essentially re-learning VB for the first time in 15 years to try and accomplish this task - I have a project to do for work which involves taking .doc files which contain hundreds and hundreds of names, addresses, e-mail addresses, and amounts they donated to the non-profit I work at, and inserting them into Outlook's contacts. I'm trying to piece together the bit I've figured out about Outlook/VB integration to do so, but unfortunately, most of the information I can find is the other way around - getting info FROM Outlook and inserting it elsewhere.
The doc file is essentially formatted like this:
FirstName LastName
423815 Central Park West
FirstNameLastName@Somthing.com
$3000.00
And repeat.
So for the email addresses, I obviously need to look for the @ and copy from the previous space or line break to the next - that's the theoretically easy part, along with the money donated, since I can similarly look for the $. The part that I forsee stumping me is, how to discern first and last name, and treat them accordingly, entering them into the right fields in Outlook? Same with the address.
I am working in VB.NET08 and Access Database. Generally we send or update a Value into a Column in a Table through any control like TextBox or Combobox...etc.
Ex:
rscitycountry.Fields(1).Value = Me.cmbpersonalcity.Text
rscitycountry.Fields(2).Value = Me.cmbpersonalstate.Text
rscitycountry.Fields(3).Value = Me.cmbpersonalcountry.Text
But I need to send a Value or Insert a Value in a Column through Condition. So I wrote a SQL Query for that. By Using this SQL Query I want to insert a value in a particular Column. How can I Update This Column Value in a Table? My SQL Query is :
"INSERT INTO tblPersonsInstitute(InstituteID) SELECT tblInstitution.InstitutionID from tblInstitution where tblInstitution.InstitutionName=" & Me.cmbInstitute.Text & " "
By using the above Query How can I Use? Where I can update??
