I have a table in access with 3 columns 1st is called userid and is a primary key and auto number 2nd is first name 3rd is last name. I have a button on my form and when I click it I want it to load the last userid listed in the access table and put in a textbox, say txtuserid. So if the records in the table looked something like
0001 james cold
0002 nick case
0003 john doe
When I click the button I want the last user id in the records to come into the textbox, so in the example that would be 0003, my connection is already set up.
provider4 = "PROVIDER=Microsoft.Jet.OLEDB.4.0;" 'database provider established

View 6 RepliesI am a former IT student and have not used VB in a little while but feel it can come in handy to help me complete some tasks at work.I am trying to write a small program which will open a url + a number for each number entered into the textbox. As an example lets say the website is "www.google.com/id=" and I enter into a textbox 3 values such as "134,325,2112", www.google.com/id=134, www.google.com/id=325 and www.google.com/id=2112 would all open at once.
The purpose of this is at work, we have an employee database and would like to load multiple employees at once (upto 6 at a time) to compare profiles. The issue with doing this manually is we have to fill out the search criteria for each, instead, I would like to load a link with parameters in it already filled out + the employee number we are searching for each number entered into a textbox on a VB form.
I am trying to write a vb2008 program that allows a user to select an airport from a combobox and then once the value has been selected it searches a comma separated text file once it has found the airport selected ( always the first column in the file) in the file it populates 8 other textboxes with the row data from the file. The idea is to select the airport and then it calls up the radio frequencies associated with the airport.I assume you have to call the data into an array and the search thorough the array until the combobox.selectedvalue = the value in the array, but i am unsure how to do this Ideally I would like to be able to the user to add data to the file thats why I used a combox, but I am having trouble trying to get the boxes to populate so first things first.

View 5 RepliesI have an xml file called "QuotesxmlDoc", in my program I have written code for a search screen that searches the xml file for titles or keywords in quotes saved and the information is then shown in a datagridview, see the code below:
Private Sub btnSearchQoutes_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchQoutes.Click
Dim xmlnav As XPathNavigator
[Code].....
On the main screen of the program, I want to show all the saved quotes from the xml file in a datagridview, I just need to show the date, category, author, title of the quotes, I also need the datagridview to refresh everytime a new quote is saved.
Try something along these lines:
TextBox1.Text=(dt1.rows(DataGrid1.CurrentRowIndex).item(0).tostring)
where dt1 is the datatable you're using as the data source and you want the data from the first column of the grid to be shown in the text box.

Our application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"

These additional details are pulled from a database, which takes a bit of time to finish.If I run the DB query from the form's load event, the form doesn't show up until everything in the load event has completed, which can take several seconds.I want the form to show up instantly when you double click, and all of the fields to be populated once the data is ready.Is there an event I should be using other than Load?
