I'm populating a DataGridView control using the Add Row method and an object array as the basis for that new row. All the cells work fine except the DataGridViewComboBoxCell which gives me an exception titled "ArgumentException: DataGridViewComboBoxCell value is not valid".
How do I resolve this problem?
thank you,

Hi there,
We have a menu system built using the treeview control. All items of the menu are stored in an XML file and populate at runtime.
I need to implement a new feature to this treeview control and its causing me to pull my hair out (not that I have much to pull out)
I need to implement a user rights feature, where each page of the menu can be assigned to a user, if the user has that page, they see the menu structure etc.
For example, if I have the following structure:
Menu
-Sub heading 1
--page 1
--page 2
--sub heading 2
---page 3
---page 4
-sub heading 3
--sub heading 4
---page 5
User 1 has the rights to page1, page 3 and page 5 so his menu would be
-sub heading 1
--page1
--sub heading 2
---page 3
-sub heading 3
--sub heading 4
---page 5
User 2 only has access to page3 and page 5 so their menu should be
-sub heading 1
--sub heading 3
---page 3
-sub heading 3
--sub heading 4
---page 5
Getting the page access and finding user credentials isn’t an issue, but I’m really struggling to figure out some logic to generate the menu, keep the subheadings there if they are needed and not show anything that is blank.
Has anyone done anything like this in the past? Any tips would be great, and code would be fantastic – but I’m really only looking for ideas on how to complete this.
I’m sure I’m making it harder than it needs to, and I’m also sure loads of people have done this without a problem
Thanks in advance

Look at TreeViewAdv on SourceForge. It has a 'mode' to pull node data on demand, and that appears what you are looking for.
Hope it helps

Hi,
I have a variable called "toDate" which is a string containing "10/1/2006". I need to pass it to a SELECT statement as follows:
selectTransactions.CommandText = "SELECT * FROM [transactions] WHERE ([Date] > #6/1/2006#) AND ([Date] < #toDate#) ";
It doesn't work of course - how do I get the variable into the statement?

Use parameters:
myCommand.CommandText = "SELECT ColumnNames FROM TableName WHERE DateColumn = ?";
myCommand.Parameters.Add("?", toDate);
NOTE: The parameters must be added in the order they are specified in the SELECT statement. The ? represents the placeholder for the parameter.

Hey.
I know that the Structured Query Language for MDB (Access) is differrent then the SQL of MySQL.
I'm currently moving my databases from Access to MySQL, but I don't know the syntax of the SQL.
If anyone can help me, or give me a dictionary or some internet help and some samples, I would appriciate it.
Thanks alot.

That really isn't a valid reason to cross post.

They are both based on the ANSI SQL-92 standard so there should be enough similarities to get you started.
Other than that you should read the documentation for MySql http://dev.mysql.com/doc/refman/5.1/en/index.html[^]. That is the best solution for you because then you will have a better understanding of what MySql is doing.

what do u mean by before or after?!!!
<br />
private void listbox1_DrawItem(objectsender,System.Windows.Forms.DrawItemEventArgs e)<br />
{<br />
<br />
this.listbox1.RightToLeft=RightToLeft.Yes;<br />
<br />
}
|
|
|
|
|
do u try set this.listbox1.RightToLeft=RightToLeft.Yes; when you initialize the listbox control?
|
|
|
|
|
I tried it before, but it didnt work.
|
|
|
|
|
may be you need contact MS support.

Are you eventually using Windows 98 or Millenium Edition? MSDN says that the ListBox.RightToLeft property has no effect on these platforms.

Hmm, in this case I think it has something to do with your custom implementation. If I drop a new ListBox onto my Form and assign RightToLeft.Yes everything works fine.
