View 2 RepliesI want to make 2 planning forms, one for persons and one for materials. The most ideal situation is when it can be in 1 form and switched by using an option field at the top.
- The information is coming from a SQL 2008 database.
- Vertical the persons or materials must be shown(dependent of the option field).
- Horizontal every day of the year must be shown, so the number of columns will be 365.
- At the crossing the number of hours must be shown.
- The form must be build as fast as possible.
I tried to create a datatable dynamicly and use a Datagridview. The advantage is the information, which must be shown, can easily be changed. The disadvantage is it is slow.What is the best method to do this in VB2008?

View 2 RepliesI have a "For
Each
Row As
System.Data.DataRow
In
DataTable.Rows" type loop. I want to save the contents of a field to use in subsequent processing.
It looks to me like the proper way would be to use something like the following:
Dim saveCatalogWorkID As VariantType
For Each clsWTRow As System.Data.DataRow In clsWTDataTable.Rows
saveCatalogWorkID = clsWTRow.Field("CatalogWorkID")
Next clsWTRow
I've got two lists, ones a DataTable, the others an array list. I want to populate a CheckBoxList with the contents of the DataTable, and check any entries that exist in the array list:

3 Prod2
5 Prod3

The columns are overlapping each other and am not able set the printed page to landscape
I checked the example in the code bank but it is way more complex than what I need
I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings

My application must display some data in Datagridview (status of COM ports communication) and i Used .mdb databases before for faster search and Datagridview update. How i understand Datagridview is importing data from DataTable and data in DataTable is imported from .mdb file, so i decided to make shortcut - stop to using .mdb file (data must be erased every time application start and it is useless make .mdb file and erase it every time, becouse it is increasing even when drop is used) and using only DataTable..
I want to row in Datagridview change it color to red when it's Collumn(6).text countains %error% string..
When Error in COM port is starting, i can fast find row in DataTable for that port and write information that Error accured for that port and DataGridview automatically updates:
Dim RRow as () DataRow
RRow = ds.Select("Port = 'COM3')
RRow(0).Item(6) = "Error Opening COM3"
