before re-inventing the wheel, i want to ask you how i can do this best: I have a VB.Net application that uses a database connection to MS SQL Server 2005 (express version). There are users that input data with the application into the database lets say once to 2x an hour to once a minute. I want to do backups like this: Once a day or once a week (in the evening) a full backup, and whenever the program/user is idle for lets say 10 Minutes, i want to do an incremental backup (so that it does not take so long until he can work on after the backup).
There are no big security issues, just copying the backup data files to a network share / a different computer or server would be fine. i guess the average db size may be 300MB, but the daily increments about 1MB.

This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

View 1 RepliesThis is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?
View 2 Repliesneed to have a summation field in each row of a grid in visual basic. Each row needs to calculate the remaining quantity of its row and all other rows beneath it. Thus the subtotal field in the 1st row would equal the sum of the shown quantity field for the entire grid.The next row would include its value and all those beneath it. Its subtotal value would be less than the subtotal of the row above it (by the quantity value of the 1st row). My code for the grid is very simple I just can't figure out how to add this iteration.

View 5 RepliesAs I understood , The property grid is given an object which it can manipulate by extracting its Properties using reflections.
My problem is that I have a set of Parameters that is determined during run-time , thus I can't staticly compose a class with properties to represent this set.
I have two idea in mind to solve this problem but both are complex and will probably consume lot of time , infact i will say they are not practical under my time constraints. One is to use Reflection Emit in order to define a class dynamically and the other is to dynamiclly build a C# source file and then compile it using CodeDom.
Can Property grid behave in a different manner( other then extracting the Properties of an object using reflections ) that can suite my problem?
I want to say that the reason I went to the property grid from the begining was its ability to provide realy nice Data Retrieval UI for common types.For color you autometically get a palette , For dataTime you automatically have a nice calender. I would like to get those things automatically If possible.
Visual Basic 2005 I have a DataGridView on a form. It's bound to a DataSet, and I'm working by way through the dataset doing various things to the records based on the "status". What I would like to do is scroll the grid, so that the row that the program is 'looking at' is in the middle of the grid.
View 1 RepliesI have the below code that i am trying to have two datagrids with a grid splityter in the middle. The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking?
