View 3 RepliesI create a hyperlink that when clicks generates a url like so:
[URL]
And I read it into a text box like so:
Me.txtTags.Text = CType(Request.QueryString("Tag"), String)
But the result of this is that the textbox txtTags will only contain C and doesnt have the ++. I tried [URL]and the # is missing as well. But if I look at the address bar these values are there....

I'm currently testing an application that I've just finished developing and i seem to have a memory leak problem that i can't figure out. If i left open Windows Task Manager i can see that the process WMIService.exe is constantly taking more and more
memory. Starting from 40 000K, it was at 590 000K after 5 days.I was able to figure out which part of the application is causing me problem. So i've made a smaller application to figure out the problem but i just can't find the problem. Here is the code:
Private Sub WmiStartToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WmiStartToolStripMenuItem.Click<br/>
LaunchWMI()<br/>
End Sub<br/>

I am trying to write a query on an .aspx webpage connected to an .aspx.vb file to access some parts information on my mysql server. Everything works fine except for one poorly named file, which keeps breaking the query. The fields name (with the table name in front) is
invf12.PRICEE(1STU_M)
Those brackets seem to be the problem. I have tried putting single quotes around them, as in
invf12.' PRICEE(1STU_M)',
I can't do anything about the fieldname. The query in total looks like this:
Protected Sub LookupPart_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LookupPart.Click
Dim strSQL As String = "SELECT invf12.ITEMCODE as Part, invf02.DESCRIPTION as Description, " + _
"SUM(invf12.QUANTITYONHAND - invf12.QUANTITYRESERVED) as Available, invf12.PRICEE(1STU_M) as Price" + vbCrLf + _
"FROM invf12, invf02" + vbCrLf + _

I have the following query that executes when my form loads. It's the rowsource for my combo box. The query is fine and populates the combo perfect, however, when i click into the combo box I cannot click out of it or even close the form. I have tried taking out the line of code that fills the form via table adapter on load and it works fine (opening the form unbound by the main table). Has anyone run into this before? I have another combo box on the form setup the exact same way and this is not happening. I've experimented with different datatypes etc....
code to populate combo box:
Public Shared Function LoadCallSource() As String
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and Settingsdiw07My DocumentsDaily Backupsphone memo backend.mdb"
[code]....
If I take out the line
Me.MemoTableAdapter.Fill(Me.Table_Memo.Tables("Memo"), intMemoID)
The Combo boxes do not act up or "Lock"
I have a string of characters, but I would like to have a string of hexdecimal characters where the hexadecimal characters are converted by turning the original characters into integers and then those integers into hexadecimal characters. How do I do that?

View 3 RepliesI have a database that I would like to filter characters from anywhere in the field. Example the letter A is typed into textbox1 and in the grid every field that contains an A is show. Like dash, lap, trap, apple. Currently with the query I'm using it will just go from the beginning of the field. I get "Index was outside the bounds of the array". The code is as followed:
Dim filter1() As String
filter1 = TextBox2.Text.Split(" ")
Sheet1BindingSource.Filter = "Stationary_location like '" & filter1(0) & "' Stationary_location like '" & filter1(1) & "'"

I need to create a console program that allows you to enter a string, of which is then outputted in reverse.
Sample:
Input: Diewas
Output: saweiD
Apparently I need to find out about strings and will also need to use a loop.
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

Basically what happens is each time it loops through it adds a number to the end of the string, and by the end I should end up with an array full of string in a format like "111 222 333 444 555 666" but I end up getting strings like this "111 111 222 222 333 333". The weird thing is, if I add a message box in every loop it works fine, but obviously I don't want a message box pooping up every time it loops through. What is causing this and how might I fix it

I used the data wizard to create a binding source, and table adapter, etc. I have a form and I have the fields on the form. All is good. The data is loaded via the .FILL method using the DEFAULT FILL,GetData() funtion created by the wizard. All is good. Now I want to filter out some of the records so I created a new FILL method (using the data source editor).
It is called FillByCountry() and the SQL statement looks like this "Select * from StampCollection WHERE Country = "Canada". Simple enough and when I test the query, I get what I expect. Now - suppose on the form I have a button and I when the user presses the button, the filter is enabled. So when the form loads, I have the standard lines to load the data... StampCollectionTableAdapter.Fill(SCDBDataDataSet.StampCollection)
I have a list(of t) and I got a iqueryable(of a)
I want to filter out any item from the iqueryable(of a) where a.id = t.myotherid

View 6 RepliesI'm trying to access the SQL DB I have designed within my project in Visual Basic 2010 (.NET code seems to work for me 99% of the time) at runtime so that a user can select a method by which to filter a DataGridView.I have a fantasy football draft application that fills the DGV from a Table Adapter. The database is named NFLPlayerDataBase.mdf, the dataset used to fill the DGV is TabNFLPlayers11BindingSource1, the table adapter is TabNFLPlayers11Table Adapter1. The DGV is dgvDraft. Idk if that helps at all.If the user wants to look at only RBs while making their draft choice, I want them to be able to select RB from a drop-down and have the DGV be filled with the query that selects only RBs from the table. I have the drop-down already set and am able to fill in the DGV when the form initializes. I just can't get it to fill with the query request for a specified position.The table I'm looking to use from the .mdf is tabNFLPlayers11 and the column header that will be searched through the filter is "Position." Options are QB/RB/WR/TE/K/DST and will be selected by the user from a drop-down.I cannot find a way to even open the connection whenever I change the value of the drop-down.

I'm develloping a small application over na Access 2007 database. how can i pass the value of a combobox to a query being built with the query builder tool?If I use ? in the Filter column I�m prompted to enter the value but what I need is to pass the value of a combobox in a form. I tried to use:
HTML
=MyForm.MycomboBox.Value
but it is ignored, interpreted as the value to be filtered.
The data was being read from a Gridview which had the html encoding. The solution was the following...
Dim Sht_Text As String = HttpUtility.HtmlDecode(row.Cells.Item(0).Text)
I am trying to prevent from having to escape apostrophes and other special characters in my string variables by using a parameterized query with an OleDbConnection. I have all of the parameters in the same order, the insert is working, it just does not maintain the characters. I keep getting those pesky html codes. I am trying to insert into an Access db from a web pages. As I mentioned, its working, just not the special characters.
Here's the code:
Dim pConn As New OleDb.OleDbConnection pConn = New OleDbConnection(cb.ConnectionString)
Dim SqlString As String = "INSERT INTO Strings (Mlt_String_ID, Lng_ID, Strg_Name, Sht_Text, Lng_Text, Alt_Text) Values (?, ?, ?, ?, ?, ?)"
[code]....
jp and en records already existed, the insert of fr record pushes the html codes for the small circle which represents the degree symbol. Happens for all other special characters as well.
