I don't have any code to put for trying to use an arraylist because I had to start over. Or is there a simple fix for duplicate names in a sortedlist?
Thanks!

I have created a usercontrol in vb.net, but i want the ability to add other controls to this using the form designer?
This already happens in visual studio, for example when you drop a panel on the form and then drag and drop another control, button, panel, anything into that panel in then adds it to the control.
how can i add this function to my control?
e.g
Private Sub DragDropControl_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles MyBase.DragDrop<br />
<br />
'gets the control<br />
<br />
End Sub
Private Sub DragDropControl_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles MyBase.DragEnter<br />
<br />
'reads the data and check weather this type of control can be dropped<br />
<br />
End Sub
thanx

So, you want to drag a control from somewhere on your form, onto your usercontrol, at design time? Do you just want it to be visible there, or do you want it to be part of the control?
Normally, the drag an drop features for controls handle data from one control to another. What you want to do can probably be done, but it may take some work.

Basically my usercontrol is like a toolbar control that you would move other controls onto, but like you say Roy yes the controls added would have to then become attached or added to the main base control.

OK. What you will need to do is, as the control is dropped on your user control, identify what type of control it is.
I assume that you want this control to be persistant (i.e. still there when you restart your app later). If so, you need to store a list of controls to be populated on your user control. You could store the list in an XML file, or in the registry.
Finally, you need to dynamically create the controls; both at startup, and when a new control is added. Remember that you are not actually dropping a control on your usercontrol, you are identifying the type of control.
Sorry is this is kind of vague. I have not actually done this. But this is how I would try it. Hope this helps.
Roy.

Which of the following is faster :
1. if drRows.Length then
end if
2. if drrows.length > 0 then
end if
3. if Cbool(drrows.length) then
end if
Any Suggestions?
Thanks

It's rather easy.... test it!
Do a 1000000 loop and clock it or in a smarter way use system ticks (read them before and after the loop, the difference is the elapsed time).
|

|

Yeah..it would be easy to test. My guess it #1 is the fastest. All three are doing drRows.length but #2 and #3 are both doing an additional operation.

My suggestion (and dare I say the 'correct' way) is to use (#2) because you are comparing "apples with apples" and not forcing an implicit (#1) or explicit (#3) type conversion.
The conversion may cause problems in the future and there is no guarantee that (#1) for example will evaluate to Boolean, nor (#3) evaluate to False when the value is zero.

Thanks Briga, dotnethead, and Steve for your replies.
As suggested by briga, i ran a test program with loop of 9999999. When i run the test about many times, each time the result was different. Some times Case #1,#2,#3 all took same time, at times #1 was the fastest, at times #2 , another time #3 and at other times there was a tie b/w the cases. so could not reach a conclusion.
As Steve pointed out [it was the reason i posted the question] #1 involves an implicit type conversion [integer is converted to boolean], #2 a comparison and #3 an explicit type conversion, it is difficult to say which would run faster.
After much thought i too reached the conclusion that #2 is better [it atleast explains the code better]
Thanks every one

Hi All,
In my project, I want to check the version of Oracle SQL*PLUS used. The user will browse for the Oracle SQL*PLUS executable and give the path together with exe name in a text box. But if there are two SQL*PLUS exes installed in the machine (One with version 8 and the other with version 9), I want to check the version of the SQL*PLUS executable. Only the executable with version 9 will be working for my project. The confusion is that there are two types of SQL*PLUS available for each version. One is a windows based utility with name SQLPLUSW.exe [Oracle Version 9] and PLUS80W.exe [Oracle Version 8]. The other is a Dos utility with name SQLPLUS.exe [Oracle Version 9] and PLUS80.exe [Oracle version 8]. My problem is I am not getting the version of the Dos utilities (PLUS80.exe and SQLPLUS.exe) using the GetFileInfo() method.
Can anyone suggest a method to get the version of a DOS-based utility program?
Thanks in Advance

DOS .EXE's don't have this kind of metadata in them. About the closest you're going to get is probably checking the file's date/time stamps or file sizes for the correct version. Or, possibly looking for some kind of signature in the .EXE file somewhere. You'd have to know what the differences are between the two versions of the same file, though.
