How can I count how many rows are returned by a dataset and then show the total number of rows as extbox.text and read-only so that the user can only see them but not change them?
so far I have this but it dosent return a number and says it cant find table 0:tbRecordsFound.Text = ds.Tables(0).Rows.Count
I created a DataSet using the DataSources wizard. I can display the rows of each Datatable one at a time. But in this case, I needed to add a new DataTable (newDT) using the Add New Table Adapter control(?) on the toolbox. newTable is derived by JOINing three different existing tables (or, dataTable) in my DataSet designer. The query works fine and returns all the data as expected. Trouble, if I try to display the rows of the newDT on textboxes, I get a NULLREFERENCE Exception.

I have a dataset column that I am keeping comments in. If the row has no comment in it(defualt string value is "", not NULL), I don't want it to show up on my report. How can I fill only the datarows that have text in them and not the ones that are empty. I've tried to filter the columns results by Not Nothing, but everything shows up. I'm guessing because it's actually not NULL since the string is "". How can I filter these results correctly?

I have written an app (CMSXML) that writes its output to a textbox, but the textbox only displays white. TextBox1.text returns the text I wrote to the text box.
I have started with a new application and what I write to the textbox, is visible in it.
I have set Textbox1.enabled = True and Textbox1.visible = true, but I can't get the text to appear. I think the solution is going to be pretty simple, but it has illuded me thus far.
I have a textbox,it should display something like "please enter your name" by default.

View 3 RepliesI'm using VB 2008 and reading data from an access 2003 database.I have a query setup in access - read in as a 'view' in vb ... that is showing results of first pass yield. total good parts... total bad parts... and percentage of yield.in my access query - i have the percentage displaying properly using the column format in access... however - on my form - the data source comes in as a textbox...by default.I can't seem to google the right question - but right now on my form, even though the dataset recognizes it as a double precision number - the option in the datasource tab - shows it as a text box or data grid right ...
so on my form i have the text box or details option... but my text box shows the percentage as a long decimal ... .98936524 or whatever... what's the correct string i need to format the textbox.text to display a percentage?I tried format(val(textbox.text), 0.00) that didn't do anything... and I did this under the form load section after the data sets were filled.
