I'm new to VB 2008 and was wondering how to apply 2 toned back color to my datagridview column headers or listviews. Where the color is lighter at the top of the column header and then becomes darker towards the bottom of the column header. It seems most apps use them these days.

I am populating a datagridview with data from a table and some unbound columns This is a large table and I want the form to fill the screen and the datagridview to fill the top half of the form. To do this, I have put a panel on the top and a panel at the bottom.I have anchored the dgv to the top left and docked it to the toplumnHeaderHeightSize is AutoSizehe issue is that the ColumnHeaders are not visible unless I click on the restore down button on the top right part of the screen

View 1 RepliesI am developing a project using VB2010. In the attached example I created a Form.
On tha form I put a GroupBox Containing a DataGridView.
I am trying to set, at Design time, the ColumnHeadersDefaultCellstyle Font of the grid, defining the Font, the size and the style (Bold). After saving the project or running it, The Font properties of the grid headers are changed to the Font properties of the containing
GroupBox.
Why is that so? How can I set, at Design Time, a different font for the Grid Column headers and the GroupBox?
To demostrate the problm - Try to modify the Font of the grid headers, in the attached example,
to "Bold" "Size 12", Run the application and see the result.
Im trying to effectively, Save a listviews items to A database (after clearing it) then load it all back in to the listbox, would this do it? becuase it just doubles what ever is in the listbox @ the time,
Dim ConnStr As String = "Provider = Microsoft.Jet.OLEDB.4.0; Data Source = " + System.Windows.Forms.Application.StartupPath + "data.mdb"
Dim DT As New DataTable()
Dim SQLStr As String = "DELETE * FROM [keys]"

I have added a custom Control to my project, but every time I edit it and rebuild the form that I use the custom control in adds the project name in front of the control and won't compile. i.e. Project name = MyProject, Custom Control name = MyControl. When I rebuild the project after editing my control I get an error, MyProject.MyControl doesn't exist. If I remove the MyProject from the line it compiles and runs fine until next time I edit the custom control.
I can't figure out what I would be doing wrong to cause this, or why it is putting the project name in front of the control, but then not accepting it. I am also struggling figuring out how to change the back color on an individual cell in an Datagridview Combo Box. The style.backcolor property of the cell doesn't seem to do anything.
How I can change the back color of a single cell of a datagridview in runtime?

Parameter name item. Note: Have 2 listboxes 4 textboxes double click listbox2 and it fills in the four texboxes (now it needs to put it back into listbox2 in the same place it came from but crashes. I marked the area and underlined where the error message was coming up. So double click a selection in listview2 (fills 4 textboxes) then double click textbox2 (should return text data back to listview2 in same spot) but crashes. See code below.

I came across this great article on creating a custom datagridview column which creates a graph-like effect in the cells of a custom datagridview column:[URL]..Does anyone know how you would edit this to format the number in the cell as a percentage? And does anyone know how you would set this up to take 0 values which do not create any graph effects at all.I have been trying to do this but keep getting errors.

I have a csv file that is being sent to me in this format[code]...
This is the only way this file can be exported from the system that is sending the information.
The second item is the Header and of course the 3rd would be the value that needs to be inserted into the row. How do I import a file like this. It is going to be sent to me every 5 minutes so I have to be able to extract the data shortly after the file arrives and insert it into Sql server.
In VB6, listview had HideColumnHeaders property. I'd like to use this in VB 2005, but that property does not exist.
View 5 RepliesWhat I'm trying to do is parse a CSV file that has column headers, and map those headers - ideally to a class.The tricky part is that I need to be able to support various mappings because it will be interacting with different systems that give the headers different names. Additionally, being able to combine fields would be extremely helpful.
Fortunately, the CSV will always be correctly formatted with all fields encapsulated in double quotes.

I need to create a checkedlistbox that has multiple columns and each column has a header. Is this possible? I can't really find much on Google. Here's the headers I need:
Checkbox Title Existing path Destination path
I have created these columns to the checkedlistbox I have in my form, but when it is run the headers don't show up. Also the items I'm adding don't seem to abiding to the column widths I put in. Also with the code I'm providing below the items don't display as multiple rows, meaning each item doesn't get displayed on a new row, but in a new column.

View 7 RepliesI am using VB.net 2008 express edition. I have figured out how to use some of the code snippets for the open xml sdk to create a drop down list of all the sheets in an excel file. I can also use the code snippet to get the value of an individual column header. What I want is a drop down list of all column headers. I could create an array containing the alphabet and loop through each column based on the alphabet letter in the array. I would then just exit the loop on the first column with no value returned for column header...but there must be an easy way to return all headers in one query of the xml.
