In the solution explorer click on the form and then click it again (like windows explorer) so that you can rename it. When You rename the file it should automatically rename the form class itself. Compile after each rename to ensure that the application still compiles. If the application doesn't compile then the form renaming process won't work properly.

I have a Combo Box control and during runtime I want to remove some of the Items in it according some conditions. How can I achieve this ?
I wrote the code for this
ComboBox1.Items.Remove(Index)
ComboBox1.Refresh()
But this doesnt works and still the item is there after running the code.
Could anybody please suggest what is the correct code.
Thanks.
|
|
|
|
|
use this property
combobox1.items.clear()
might it work
|
|
|
|
|
Thanks Ravi for your reply.
The code you have supplied clears all the items in the ComboBox. I wanted to remove a particular item depending on the condition i have. I found the correct code for this and it is :
ComboBox1.Items.RemoveAt(index)
Thanks for your response.

I have a DataGridView control in a PC Project. I want tooltips to appear in the cells of a specific column...these tooltips will be different for each row. I currently using this code:
dgvMyGrid.ShowCellToolTips = True
dgvMyGrid.Columns("MyColumn").ToolTipText = "Test HeaderCell Tooltip"
For Each dgvr As DataGridViewRow In dgvMyGrid.Rows
dgvr.Cells("MyColumn").ToolTipText = "Test Cell Tooltip " & dgvr.Index
Next
I am able to see the Test HeaderCell Tooltip when I hover over the headercell in the column, but the tooltips in the cells of the grid are not showing up. Is there another setting I'm missing or something? Anyone got any ideas?
|
|
|
|

I finally figured out why it's not working. To make my form look nicer, I set my grid's visiblity to false in design, and then set it to true once the entire form has loaded. However, there are certain settings on the grid that just don't seem to take effect if the grid is currently not visible. I guess tooltips is one of those items. (Other ones I've found are fonts/colors/etc.) So I guess I will have to loop through the grid again after I've set the grid's visiblity to true, unless someone else has a workaround for this issue???

Hello everyone,
I have developed code using Visual Basic in visual studio 2005.
It runs fine when i run it.
Now i want to publish it on the www web.
Could anyone please help me out how to do that?
thank you

the www web ?
The obvious way is to put it in a zip, and give people a link to the .NET framework.

I want to put my question in a more appropriate way.
I am really sorry for the way i put my question.
I am really new to the programming world.
So please pardon me.
I want to deploy it on the web and the user have to open it on the browser like explorer. Its basically a game sort of thing. I want the user to play the game directly on the web browser.
Could any one help me out on this?
Thanking you.

Hi
I need to save an Excel file as (Excel 97-2003)
For the code below, I have a reference to Microsoft Excel 12.0 Object Library, which I assume is for Excel 2007.
When I open a workbook saved as below, I get an error message saying the workbook is not in the expected format.
Previously I used a reference to Excel 10.0 which worked fine, but I cannot find that anymore when adding references.
I guess I have two choices:
a) How do I reference Excel 10.0 Object Library?
or
b) In the code below, what do I replace "FileFormat As Object" with to specify that the file must be saved as an older Version?
Private Sub ExportExcel()<br />
Dim xlApp As New Excel.Application<br />
Dim xlBook As Excel.Workbook<br />
xlBook = xlApp.Workbooks.Add<br />
<br />
'Write stuff to book here...<br />
<br />
xlBook.SaveAs("MyBook.xls", "FileFormat As Object")<br />
xlBook.Close()<br />
xlBook = Nothing<br />
xlApp.Quit()<br />
xlApp = Nothing<br />
GC.Collect()<br />
End Sub
|
|
|
|
|
Found my answer...
Use one of the Interop.Excel.XlFileFormat formats
Interop.Excel.XlFileFormat.xlExcel8 seems to work fine
