Refresh The Textbox/datatable To Re-run This Command?
Nov 6, 2011
This piece of code grabs a customers hire record using their hire ID and displays their details in multiple textboxes. It all works fine and well, however, I can only run it once. If I type in another customers hire record ID it just displays the first customers details that were materialised, which I assume is because the datatable has been populated and not refreshed based on the new hire record ID I've entered.
[Code]...
With this I can search a column of a datagridview for a match. It works all fine and well, until I insert a new record into the database at which point I refresh the datagridview to display the newly added record. After I do this, I can no longer search using the textbox. Once again, I'm not quite sure what to do to fix this issue.

The following code loops through the rows of a datatable to process each record which has a Processed column value not equal to -1. When a record is processed, its Processed value is updated to -1. As a record is processed, the code within the Do Loop may add a new record to the datatable with a Processed column value equl to 0. All of that works as intended. My test set record gets processed and a new record is added.At the end of the For.Next code, there is a line , "clsWTAdapter.Fill(clsWTDataTable)", which I intended to refresh the rows so that it would include the newly added record which would then be processed during the next iteration of the For...Next sequence. This is not happening. What am I doing wrong, and how can I refresh the rows and process the newly added records?
I found this line in an MSDN page about DbDataAdapter Fill Method (DataTable) at [URL]"The overload of Fill that takes DataTable as a parameter only obtains the first result. Use an overload of Fill that takes DataSet as a parameter to obtain multiple results."Does this mean that I am on the wrong trackby using a datatable where I should be using a dataset? Does "multiple results" mean filling the dataset multiple times like I am trying to do with the datatable?

I have an untyped-Dataset with two related DataTables, and I have a grid bound to the parent DataTable. I used the WriteXMLSchema() method of the parent DataTable in order to save the schema in a xml file. Then I opened the file with the Notepad, deleted two columns from the schema file and saved it. After that, I used the ReadXMLSchema() of this DataTable but -contrary to what I would have thought- the DataTable's structure was unchanged. Using the debugger I noticed that after calling the method the number of columns was the same. Why? How can I make the DataTable's schema to be changed by using a file?
notice that I am using the DataTable's methods and not the Dataset's because I do not want to touch the child DataTable.

on a windows form i have a combobox called currency, it is populated by a table-adapter called exchan-gerate which is turn populated by a dataset called mydataset. on form load, i issue update commands to the back-end database that holds the table which populates the dataset - they work. if i look at the update to the combobox, they are not reflected until i exit and restart the app - then they're fine. further down the form load i've tried:
Me.exchangerate.Update(Me.DataSet.Currency)
Me.CurrencyComboBox.Refresh()
am i missing something silly to have the values in the combobox change and refresh at the time of the update to the database? as i said, an exit and restart of the app displays the accurate data.

I have set up a class as a facade to access the session variables for my app. In this app I store an entire dataset for a particular employer as a session variable.Within one of the sub pages I have a button that adds a row to an existing table stored in that dataset.
Dim curRow As Data.DataRow = mySession.tWorksiteOtherMeasures.NewRow()
curRow("lngWorksiteID") = getSelectedWorksiteID(getSelectedSiteID())
curRow("strMeasure") = ""
curRow("lngStatusID") = -1
[code]....
When in the code to add the row the row count increments and the row exists. Once out of that scope the page refreshes due to the button being contained in an updatePanel. When that happens and I click the add button again the row counts for that item reset to 0 and 1 after the code runs. The previous added row is gone.Here is how the Dataset is assigned from the web service:
Public Shared Sub loadDSEmployer(ByVal strUserId As String)
Dim myService As New someservice.service
mySession.dsEmployer = myService.GetEmployerAndSites(strUserId, isInternal)
End Sub

I was wondering if there is a way to change the Fill command text of a datatable before issuing it.I need this because the table I am opening has over 15 thousand rows and it hangs for a while in the network when filling the table. So I would like to tell it what to SELECT instead of getting the whole table and then applying a filter.If there's a way of doing that without changing the fill command, it will also work for me.

I am working on a simple program called "Who's Connected?" where it runs a command (netstat -aon) and then displays the results in a multi-lined textbox. However, when I press the button that will run the command, it tells me that it can't convert the string to an integer or something. And when I did manage to get it to convert to an integer, it really showed an integer in the textbox instead of the connections and IP addresses. What do I do? Here is the code I have: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'Running command and displaying results in textbox1 TextBox1.Text = CStr(Shell("netstat -aon"))'Results end up being a triple or quadruple digit number End Sub

Similar to using VAL(a$) to return the numerical value of a string, is there a function for returning the solution of an equation that is user-typed into a textbox? For instance, user types F$=(a+b*x)/(c*x^2-d*x^3) where the variables of the equation are either pulled from a textbox or derived within the code. I am looking for something like F=Solve(F$).

I want to run some dos commands (eg: a ROBOCOPY) and show the output from this realtime in a text window to show the user something is happening.The command may take a number of minutes so it's important the output is showing in the VB application realtime, and not just all at the end.

I have a TextBox called Social. As you type in a Social Security Number into the textbox, it formats itself into the standard Social Security Number Format (XXX-XX-XXXX). It automatically adds in the dashes after the third and fifth number, or corrects/removes the dashes if numbers are added or removed from in front of the dashes. Also I coded the script to record the caret's location so that the caret goes back to where the caret was before the adjustment in dashes.
I used Pos and PosHold to hold the caret's location.
The problems I am having are:If I remove a number before one of the dashes, the caret is reset to '0' from using break points, it seem to jump out of the if statement before setting the location of the caret. Sometimes when a number is removed from before the dashes, the dashes are removed like scripted but, the dash is not put back in the correct location. This seems to happen primarily if you have numbers passed the second dash.

Private Sub Social_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Social.TextChanged
