Hi Beth,

I've been studying your one to many code in my efforts to learn VB 9.  I've found the videos most useful.

You did leave out one key component.  I kept getting an error after a save because my main key was populating using the temp holder of -1.  

I noticed in one of your videos, the 2008 one, you briefly mention datagridview.enter.  I capitalized on that and put the tablemanager to save upon the enter of the grid.  Then the main key was populated and the form could save smoothly.

Thanks for creating these videos, I find them very inspiring.  In the process I've installed Vista and am finding it to be a wonderful launch pad.

Thanks again,

John.

Hi Beth

i am trying to create an Attendace Sheet using VB, since your videos are not about this, i find it very difficult to do all that by myself. i am still very new to this, so do not know even weather we can create an Attendace sheet or not. and yah here in Maldives we have monthly salary nto weekly.

I'm somewhat of a newbie and this is EXCELLENT learning material - THANKS!

What I haven't found though (and it may be something very simple)... is how to create a one-to-many data entry form only not using the DataGrid. I want to use individual controls for the Child table on that form.

Hope someone could point me in the direction where I can find this.

THANKS!

Hi Calo,

You'll probably want to take a look at the DataRepeater control in the VB PowerPacks. Here's a video: http://msdn.microsoft.com/en-us/vbasic/cc411420.aspx on how to use it.

Hi Beth,

I watch all of your vedio, it helpfull and I like it, i use them to build a database application and it is really usefull, but there is one thing. while the data growing, you find that it is important to not fill you dataset with all data from the database, and no way to add new record without filling the dataset. how can i solve this, while i need to for cleaer network trafic

# Beth Massi said on March 3, 2009 5:17 PM:

Hi M Sharief,

You'll want to specify parameterized queries on your tableAdapter to narrow the results. Take a look here:

Hi Beth,

thanks for your answer, but no way else to do that without fill the dataset.

thanks

Hi M Sharief,

Yes, you're filling the dataset with only the specific records you need, not all of them.

I have looked all over the internet for your video on working with the datagrid in VB. I watch the video about two months ago and it was great. But now I can't find it. I thought I watched it from the msdn.microsoft.com website but I sure can't find it there now. Please let me know where I can find it. I created a small project while watching it and now I can remember how I did the filtering.

Please help.

Hi Tommy,

There are a bunch of videos here that use the DataGridView: http://msdn.microsoft.com/en-us/vbasic/bb466226.aspx#formsoverdata
