Specific Columns To Show Up In DataGridView?
Oct 6, 2009I only want specific columns to show up in my DataGridView, so I run a dynamic sql query to select specific columns from a table on a sql server(I know its slow, but its only used once a day). However, every column from the table shows up in the datagrid, and I can't figure out what i'm doing wrong.

Spanning Columns With A Dynamically Created Label Doesn't Line Up Correctly?
Mar 3, 2010Create a generic label method:
Public Function buildBasicLabel(ByVal labelName As Label, ByVal text As String, ByVal font As Font, ByVal align As Integer)
Dim tmpLabel
[Code]....
For some reason, the label is not lining up with the others once I span it. I'm trying to span it to get all the text to show but once I do, it starts pushing it over. I don't see anywhere where I restrict the size so that shouldn't be the issue.
I tried doing all this in the design and it works just fine. Mimicking the designer code doesn't seem to fix it either unless I'm doing something seriously wrong...
Posting images for clarity. NOTE: The borders are just to show the label alignment and the text should read "Flat-Footed AC"
IMAGE 1: Spanning 1 column (doesn't show all text)
IMAGE 2: Spanning 3 columns (still doesn't show text and you can see it's starting to dis-align)
IMAGE 3: Spanning 6 columns (Still doesn't show text and greatly dis-aligned. It should at least show all the text)
Format Datetime For MySql?
Oct 31, 2011i'm having a problem converting a date to the right format. Below is the code I am using:
Dim getDate As DateTime
getDate = DateTime.Now
With cmdParent.Parameters
.Add("@date_created", OdbcType.DateTime).Value = getDate
.Add("@last_updated", OdbcType.DateTime).Value = getDate

Jun 21, 2011i've been attempting to update a DateTime Field in a MySQL Table i've created via vb.net.

View 2 RepliesVS 2008 : Passing MySQL Parameter As Object Instead Of DateTime?
Jun 13, 2011I am having trouble with a mySQL query with the .NET connector. When I create the query, it automatically creates my parameters as objects. I usually change the type to the correct type, which in this case is Date, but I get different results passing in the parameter as a date.When I do "Preview Query" as an object, I get the correct results, but bad results as a Date. I would just leave them as objects, but it errors out when I try to pass a date in.Here's the part of my query that I'm having trouble with:

Forms :: Vb 2008 Express Form Wont Show Correctly
Aug 24, 2009I have been working on a quite complex multiform solution.All of a sudden the start up form (in fact any form I designate to start up) loads, displays and operates fine.
But when I try and show a form using showdialog the form displays behind the original form and I can�t set focus to the ide to close it down. I have to use task manager or alt f4 while the form has the focus.
Calling different forms from this one gives the same result but other forms work fine. I don�t want to redo this form as Ive done a lot of work onit.The only thing I can think of that whist I was changing the startup form in the project propertied page (file>project>properties) I unchecked the �Enable applications framework checkbox.

Datagridview - Add A Row Programatically And Have It Sorted Correctly?
Jun 5, 2009I have a datagridview named "DG" bound to a datatable. The grid has one column that requires me to determine its value, so the grid has the virtual mode property set to true.When i try to add using the dg.rows.add, i get a message saying 'operation not valid while in virtual mode'.If i set the virtual mode to false and execute the dg.rows.add line i get."Rows cannot be programatically added to the datagrid's rows collection when the control is databound"Ok....i cannot use rows.add when in virtual mode,.....and i cannot use rows.add when i am in data-bound mode.So then next thing i try is ctype(dg.datasource,datatable).rows.add , This gets the row into both the underlying table as well as the into a new row located at the bottom of the grid.
I try this: dg.sort(dg.columns("Row"),ascending) and get this "Operation is not supported when VirtualMode is set to true." i try seting virtual mode to false and get this: "Data-bound DataGridView control can only be sorted on data-bound columns."The column "Row" IS a column in the underlying table.If i click on the column header it sorts correctly.All i want to do is add arow and have it be located in the correct place in the sort order.

The column is bound to a date property, all is done using the designer.The set which I'm viewing it on is 424 entries long, there should be two entries for each date and they should be next to each other (regardless if sorting by date or string)The last few dozen entries are sorted correctly but the initial entries are not.Initially every second entry at the start is correct. Here is an extract if some of the sorting it does.(The beginning of the sorted grid is on the left, and the end of grid is on the right)
