I am about to commence coding (actually recoding) on a project that accesses 100 tables of a database, more to added at later time. About half of the accesses are queries with joins and unions. I am more of a coder to not use wizards such tableAdapter, but code more by other methods. I have read some post of this site that suggest avoiding tableAdapters, not to use them in an Enterprise environmentl, but no reasons. I would like to hear from willing to bend my ear, pro or con.
View 1 RepliesSay we have a DataGridView on the main form. I can chose to establish its properties by code or by selecting them in the Properties panel. Is there a difference between these two techniques, a loading time penalty in any of the cases especially?
View 5 RepliesOk, I don't even know if the is possible, but what I want to do is have a button that when pressed will add a new text box below each other each time it is pressed. So meaning, ther4e is text in one text box, then a button is pressed, a new textbox will appear below it and you can add text to that, and so on.
View 1 RepliesI was wondering if you can programme in a code to add buttons to a page, without physically putting them in.Ive got a customisable set of options, currently in a txt file 1 item per line maybe thinking of putting into a listbox, if a user adds an item i need it to add a button with that text on.
say i had a drink list, with my first 3 items of beer, cocktail, food, and theres a button prest for each one and i decided to sell wine, shandy, rout beer and so an so on, or how ever many items there are, could be 50 items or 100 items don't really fancy?

View 1 RepliesI think I have a simple program to create, but I just cannot find the syntax to complete it.Effectively, what I'm trying to do is search down a column where there are cells with numbers and cells that are blank. I want to search down the column and find where there are two or more cells that that have numbers, one after another. I want to add a row beneith the last number and then add up the total of that batch of numbers in that column were searching down. I know that I'll be using a loop to step down each cell in the column to check on the contents of the cell. Also I want the loop to go from the top of the colum to the last record since the list length will frequently change.

I'm trying to set the size of a box without setting it in the properties dialogue box. My reason for doing so: I have text boxes stacked on top of each other. I need to alter properties of them after I place them and don't want to scroll through the list of objects (there are a lot) in order to find that specific item. Instead, I want to place them at different places in the form and then tell them where to be located, and what size they should be UPON FORM LOAD. I can't seem to locate the proper syntax in the book I am using, but from logic I have reached the following beginning of the line of code:
Me.txtVidPro.Size = 561, 130
Me.txtVidPro.Location = 63, 258
the only part I'm getting an error on is the x and y coordinates. please help me by pointing me in the right direction.
