go to the following link to see whether al the option in the connection string are given properly or not.

http://dev.mysql.com/doc/refman/5.0/en/connector-net-programming-connection-options.html[^]

also see that the Port at the hosting environment is not blocked, if blocked then register in the exception list in Windows Firewall, or any firewall setting in the host computer

Using 'Like' in DataTable select query

I have a datatable which I wish to search for 'Like' matches. So searching for "p" would bring up the entries "p1", "Pea green", "p3" etc. I have code

DataRow[] foundRows;
foundRows = debtorDataSet.Tables["AutoText"].Select("Code LIKE " + lastWord + "%" );
if (foundRows.Length == 1)
{
....
}
else
{
....
}
but this is not working. Any pointers much appreciated.

as it is a string literal you are using, your statement seems to be missing some quotes, try this:

...Select("Code LIKE '" + lastWord + "%'" );

If column name is (FIRST NAME)
If I use as Select("FIRST NAME LIKE '" + lastWord + "%'" );
It shows error

It is a bad idea to post a question to a more than four years old thread. Most users here will not even see it.

If you got an error message, add the full message text to your question. That helps others to help you.

However, your column name contains a space. Then you have to enclose it in brackets:

Select("[FIRST NAME] LIKE '" + lastWord + "%'" );

Luc's already given you the information you need, but I'd like to suggest that you should also look at using string.Format rather than explicit string concatenation - sometimes it just makes it easier to read. So, you'd end up with something like string.Format("code like '{0}%'", lastWord);

Hi All,

I have a window form.If we change the window state of the form to the maximized then the controls under that windows form does not change their Location and the size.I want that at run time after maximizing the windows form the controls under that form should automatically change their Location and size.
Please give me the solution,its urgent.

Warm Regards,

Hi,

you can modify the Anchor and Dock properties of some controls, to get some standard behavior.
or you can add code to the Resize event to define your own behavior.

imageList with treeView

Hi all...
I have associated an ImageList with a TreeView, but now all of the nodes in the treeView has icons besides them.
Is there a way to remove the icons to some nodes, so they will be with no icon beside them??

Re: imageList with treeView

The only way I know of is to create a blank icon in the ImageList and assign that - it still leave space for it though.

I have developed the C#.net window application. Setup of this project is running on PC, where .NET Framework is installed but where .NET Framework is not installed setup is not running. So I want to install first .NET Framework by default and then start running actual setup of project.

This should be for crystal report also.

How can I do it.

Good morning swami

how do you expect a .net developed application to run where there is no .net installed ?

Secondly as a .net programmer this should always be in your mind. Before you start coding you must have decided what is a target framework for your application. e.g

Visual Studio 2003 = .net 1.1
Visual Studio 2005 = .net 2.0 
Visual Studio 2008 = .net 3.5

You must install these frameworks depending to your target framework. lastly please please please buy a book and read , you cant learn everything on the internet. the reason i say this is because in every book this is a basic lesson an author gives to his reader and its very easy to understand.

C# Desktop Apps

After slacking on the C# front for a year or two, I've decided to have another look. Previously I used C# for the web, but now I'm looking into creating desktop apps. And I'd like to use one of the latest technologies (to save me having to learn another one in a year's time...). I'd also particularly like to target Windows 7 - but also be able to make some apps for XP. My question is:

Which technology do you think is best to use for creating my desktop apps and why? Windows Presentation Foundation? Windows Forms? Other? I really don't have a clue, so I'm hoping for a nudge in the right direction! Smile | :)

Cheers.

That's a tricky question, and not one that's easy to answer. First of all, let's address a misconception - WinForms aren't going to go away anytime soon, so learning them isn't going to be wasted effort. You'll still be able to develop desktop applications in them for a long time to come.

Now, saying that, I'd choose WPF over WinForms for a number of reasons.

1. While WinForms isn't going away, it's not going to be actively improved by MS, so you're stuck with what you get.
2. WPF makes it easier to create data bound applications. Rather than having to write lots of string myValue = txtName.Text; and txtName.Text = dr[dr.GetOrdinal("MyValue")].ToString(); code, you can use two way databinding in WPF to good effect.
3. It's easy to change the look and feel of WPF applications.
4. If you want to move over to Silverlight, it's based on WPF so the transition is a lot easier.
5. Microsoft is actively targetting improving WPF, and is starting to use it in its own applications.
6. The infrastructure underlying WPF is a whole lot more powerful.
