The short answer: No
The long answer:
No, you can't send other parameters to that delegate, but you can create your own..
You can create your own doubleclick event by using the click event and track position and time between the clicks.. If you go for this solution, you should find a way to find out the double click rate on the computer...

If you say no, what's wrong with my answer I already wrote before you? I tried it and it worked. Any drawbacks in my solution I didn't saw?

USB and Framework 2.0

Hey!

Is there a way in Framework 2.0 to work against a devce connected to the USB port? like regular com ports or will we have to make a driver in C++ to make it work?

In this case we want to connect a Cell Phone to a program throw a USB connection.

Best Regards
Jimmy

Not through pure .NET, I'm afraid. You can use managed C++ and C# together to do this, search the web for more info.

Also, there are some C# serial port articles on codeproject; if you had a USB-to-Serial hardware, you'd be able to do this through managed code.

Triggering on SQL events originating from third-party application

Trickster-SWE3-Apr-05 23:43

Trickster-SWE

3-Apr-05 23:43

We have a third party application that handles some SQL management (SQL Server 2000). We do not have the source code or any documentation on how this application works.

In this third-party application, a user has to log on with some credentials and the application checks with a database if the username and password is correct.

I don't know if this is possible, but what I would like to do, is to create an application that executes a certain list of commands on the database whenever someone tries to log on within the third-party application. Since I don't have the sourcecode to the third-party application I have to write another one that executes parallell to this one.

My question is if it's possible for my application to know that the third-party application is executing a certain Stored-Procedure or a command. Are there any events/messages that I could catch?

Any ideas would be appreciated ...

Thanks

the "build application" button the size of the controls in that childcontrol change they become much larger

(note i do set the anchor value but still the behaviour is abnormal)

did you look at the sample.
anchoring is not the problem here the problem is that the size changes when anchoring is set during build the size is back normal when you run the application.

if it where the anchoring i whould be glad but i also whould of found it by now then.

pls look at the sample if you want to help.

This functionality is not exposed through the current .NET framework class library. Use P/Invoke to call the Win32 SystemParametersInfo API.

If you're running VS.NET, simply right click on the Project file in Solution explorer and click "Add Web Reference". Give the URL (*.asmx file) and VS.NET automatically generates a proxy class that you can use in your application.

Binding a DropDownList control

Ok, Ive have read many books and seen a lot of examples of how to bind a drop down list. So I am using VS .net and I use the IDE to create as much code as I can via the GUI.

Hey, I need some help to finish a project I am working on
I have a function that filters a database I loaded into a data grid it works like this:
private void selectRecordsDV()
{
string sFilter;

sFilter = String.Format("SalesDate >= #{0}# AND SalesDate <= #{1}#",xtBxStartDate.Text,txtBxEndDate.Text);

try
{

dvABC.RowFilter = sFilter;
dtGrdSales.DataSource = dvABC;
updateSalesInfoDV();
}
catch(Exception err)
{
MessageBox.Show(err.Message);
}
}
in a data view. I need it to filter one more column in the database named CustNo but can't seem to make it happen. any suggestions?

First of all, why the # ? Is this something I don't know about SQL ?

Secondly, what's the error ? That would help a lot in working out the problem. Is the text that's coming out in the proper format ? It should be in YYYYMMDD:HHMMSSSS, from memory.

Tooltip position in c#

As far as I am aware there is no simple way of changing the position of a tooltip in C#. By default it appears that the tooltip is painted below the control in question. I would like to be able to display it to the right of mouse pointer.

Tooltip appears to be sealed. Does anyone have any examples on how to hook the dll and inject this functionality? It's probably gonna be ugly -- but I don't think I have a choice Wink | ;)
