I'm trying to develop an app to import a spreadsheet into an Access 97 database. I'm using Visual Studio 08. I'm stuck on the first step! I'm trying to use the Data Source Configuration Wizard to connect to the database, and when I get to the point where I choose which tables to add, I get the following error:
<COPYtblMHPuse>
Could not get column information for database object named 'COPYtblMHPuse' This is for any table I try to add.

If it is at all possible, I would like to print a page that is layed out with labels filled with text from previousley stored information from the program. now, obviousley, because the text can change in amount, and so the labels need to be able to change in size, and if at all possible allow multiple lines, though if there is no way to do it, then an unchagable text box would serfice.
There is a problem though, the fact that the labels will be changing size means that the position of the labels needs to be variable to the previouse. Example: the box above needs to be bigger, so the box bellow needs to drop down equall to the amount that the above grows.

The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

I'm using Visual Basic 2008 Express Edition, so I have a combobox that gets filled with items from a data base made with Microsoft Acces, the combobox is filled with the values stored in a column from a table in de database so the user can select an "option" from it, I want to add labels that show the values for the corresponding row of that column. I used the Data Source panel to drag and drop the labels corresponding to the values that I want and it works it show the value that I want when I compile the application (at least I think it does, it could be that it's only selecting the first entry) the problem is that when I select a diferent entry on the combobox the labels don't refresh with the new values. How can I do that?
edit
how does Visual Basic Populates de combobox and gets the value of the other Acces DB entrys to change the .text value of the labels? And I mean the actual code that does that.

I have a program and I get time data from a sqldb and display it in a column in a listbox. What are the proper steps for adding the time as I iterate through the data in the column? I figure I will need to do some conversions on the time to be able to add it and display it as a total.

I want to be able to get the table structure / design / column information from an access database. I have created a post in the Database/Access section with no luck, here, but I am wondering if I could achieve this through vb (2008 express edition) rather than the access sql query itself. My overall goal is to compare one DB structure with another, an integrity check if you will.

I have a dataset with a number of data columns, due to sizing issues I've updated a number of the varchar columns from say VARCHAR(20) to VARCHAR(50).I'd like the DataTable to automatically grab the new column information, is this possible? I'd rather not go through each column in the table and update the length.

I am creating a program with multiple Forms designed to track multiple projects.The first form is designed to setup new projects and obtain previous projects, from there the other forms open to be filled in with information.For new projects the next forms open blank but I then need these later forms to be tied to this project name so that it can be selected from a combobox and the information will be already populated.tieing the information on the later forms to the projects populated in the combobox so that it appears when a specific project is selected.Is this able to be done without creating databases?
As an example, say I create a new project then a new form opens and I add some information to a textbox.I would then like to be able to save the information so that the project name moves to the combobox on the first form (I can handle this) and the information input in to the textbox is tied to the project name so that when the program is reopened and the project name is selected the second form opens with the textbox populated.
