VS 2005 .NET 2 WinForms
I have DataGridView in virtual mode containing huge number of rows.
When user double clicks in column separator line in grid header, application hangs: it tries to read all rows.
How to force DataGridView to resize column only by using visible lines in screen ?
I tried
AutoResizeColumns(DataGridViewAutoSizeColumnsMode.DisplayedCellsExceptHeader);
but this did not help.

Hi,
I have printed Some Names and Phonenumbers to a checkedlistbox
like;
Al PacinO, 3453454323
Now I want to add the checked names to a queue, How can I do that?
//contact Name
string contName = "";
if (oCt.FullName != null)
{
contName = oCt.FullName;
}
if (chckListBox != null)
{
chckListBox.Items.Add(contName + ", " + Num);
}
|

You can get checked items in the checkedlistbox by using SelectedIndices or SelectedItems property. Then create an instance of the queue class and use Enqueue method to add items to it. Check documentation for more information.

Hi so im following a tutorial http://www.asp.net/learn/data-access/tutorial-01-cs.aspx.
I'm trying to configure a TableAdapter Query in the configuration Wizard with a SELECT statement which has a WHERE clause at the end.
I am about half way down the tutorial and have followed it word for word.
I have entered:
SELECT ProductID, ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued
FROM Products
WHERE CategoryID = @CategoryID
But i am getting an error message on the last page of the config wizard saying:
Generated SELECT statement.
Error in WHERE clause near ‘@’.
Unable to parse query text.
Can anyone hazard a guess at what i'm doing wrong???

If you replace "@CategoryID" with "?" (without the quotes), does it work?
Take care,
Tom

You could graph the points yourself by using the drawing abilities of C#. If you want to do graphs on data you could use Crystal.

ZedGraph is a great, free library. I used it before and liked it pretty much.

Override System.Windows.Forms.Control and then override the OnPaint and OnPaintBackground method. You can then use the graphic context to draw the control.

Hello every1
In one of my project I download exe files (these are self extracting) from the internet. I need to extract these files to get a bunch of emded files to do some processing.
Can some1 suggest any utility or .NET library which I can use to extract these exe file
I have looked CP and I only found codes to extract zip files....
o O º(`'·.,(`'·., ☆,.·''),.·'')º O o°
»·'"`»* *☆ t4ure4n ☆* *«·'"`«
°o O º(,.·''(,.·'' ☆`'·.,)`'·.,)º O o°
|
|

|
|
If it is a self-extracting exe, then just run it and it will extract embedded files automatically. Winrar can also do it.
|
|
|
|
|
I have to extract the files programatically...
I can have have WinRar and WinZip installed on the target machines... but what I wanted to do was using .NET features to accomplish this task..

Hi,
There is the requirement like this:,
One Login page is there for User Name, Password. Here the LAN user can only Login. How we will validate for a LAN user using C#.
Thanks in Advance.

If you've got a Windows only application, then don't use a login form. Set the authentication mode to Windows for your website and make sure that the application doesn't allow Anonymous Users.

Would it not be a case of making an alternative windows shell to use? Then, of course, limiting that user account so that can it do nothing on the machine.

You need to run in full screen mode and use global keyboard hooks to keep the user from alt tabing, etc to get at the desktop.

Hello,
Would you mind how to teach me how to do Global Keyboards hooks?
This would be funny but i am working on the project while learning the language. I am reading the Book Visual C# 2005 but i haven't gotten to the delegates part yet.
Any help would be appreciate it.
Thanks

Hi,
I made a program that launched a outlook email window and puts a attached file in it:
<br />
private Outlook.Application oApp = new Outlook.Application();<br />
<br />
Outlook.MAPIFolder outBoxfolder = oApp.GetNamespace("MAPI").GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderOutbox);<br />
Outlook.MailItem mItem = (Outlook.MailItem)outBoxfolder.Items.Add(Outlook.OlItemType.olMailItem);<br />
<br />
mItem.Attachments.Add("D:\\test.jpg", Type.Missing, Type.Missing, Type.Missing);<br />
<br />
mItem.To = "";<br />
mItem.BCC = "";<br />
mItem.CC = "";<br />
mItem.Subject = "";<br />
mItem.BodyFormat = Outlook.OlBodyFormat.olFormatHTML;<br />
mItem.HTMLBody = "<img src='test.jpg'>";<br />
mItem.Display(new object());<br />
As you can see i want to display the attached file(image) in my mail, but, it doesn't work. The image is attached and you can see it in the attachments and dubbelclick it so it shows. But you cannot see it in de the body of the mail. The reason is because the imagelink "" in the HTMLBody isn't right, but what is right???
How do i make the link so it shows the image that is located in the attachment on my HTMLBody?
please help me???
