View 2 RepliesI'm new to VB and have bought a book (Database Access with Visual Basic)that I'm trying to follow but ran into problem right away.Have created a table (tblCustomer) and populated it with a few lines of data then I have a form with two textboxes connected to the table. So far no problem I can see the first row of the table.Next step was to create two buttons to be able to navigate in the table, one forward and one backward but nothing happen when I click on one of these buttons.

In a nut shell what I am trying to do is, pull one or more tables into a datagrid view. I am having one heck of a time returning multiple datasets. I can eleect all indavidually, but when I try to select more than one, I only get the last "table" in the list. If I could establish a ODBC connection that would be better, but this will have to work for now with some canned queries I have.

I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

View 7 RepliesVisual Studio Pro 2010 Win 7 64 bit running bootstrapped to a MacBook Pro i5 (blasphemer!!!) works really well though!!New to vb.net, have used vb6 for several years and finding the transition interesting to say the least.I have an access database with a vb.net front end all auto bound by the connection and binding wizards (I know, I know...) Not too complicated, but a simple 2 table related db. On the form the parent table shows customer details with the child table related and displayed by datagrid. I have a field in the child table for images and I have figured out how to store and retrieve images to the db. I am using the datagrid.rowheadermouseclick event to reload the picturebox on the main form as I click down the child table datagrid. Now I need to be able to click the bindingnavigator, go to the next record and have the program reload the image for the next child record. The problem is I'm trying to use an event from either the datagrid or bindingnavigator to reload the picturebox in the child table after moving to the next record, but all of the events I am trying are firing before the next record is moved to and therefor the logic I'm using to retrieve the image from the db is not working.
Anyone with an idea on how to move to the next record and then run my logic to populate the picturebox? What events might I use that fire after the next record has been populated? I know this is probably not that hard, but I have been racking my brain all day now.

How can I pull individual lines out of a multiline textbox when wordwrap=true?
For example I have a long string in a textbox and it wordwraps to create 3 seperate lines. How can I get the text of the 2nd line? The control thinks that there is only 1 line since it wordwrapped and there are no CRLFs in the string.
I have one table here with a list of UserIDs, Users, and ClientCodes. Each user can be assigned a client code to view that client's data elsewhere. Right now I have to change it for everyone via SQL Server and actually going into the table manually, but I'm trying to make a simple little program that will let the user change it themselves. All I need is a textbox that pulls the user based on a certain UserID from the table, and a drop down list that will not only show the current ClientCode they're set to, but allow me to change it and save that change to the table in the database.
What's the best way to go about this? I tried using the wizards but I guess that's not the best way to go about it. I have it displaying the correct user and their current ClientCode but that's about it.
I have the following project.
