It is - check out the AutoEllipsis property of the control.

Hello,
VS 2008
I am developing phone application. Which will have a dial pad and a display.
In the display the customer wants to have details of (call duration, number being called, status when call is connected and disconnected).
Number being called should be in the top left, Status button left, call duration button right.
I am just wondering what is the best method to go about this.
I was thinking of making a new control and inherit from the text box class. And this textbox will contain the 3 text boxes I need to display the different details. That way they can be aligned correctly in the display.
Any other suggestions or ideas would be most helpfull,
Thanks,

How about using List View Control?? That way you can display all three/four information in one line!

Hello,
Thanks for the reply.
The customer doesn't want to display in one line.
Any other ideas about a text box control?
Thanks,

Are these going to be editable fields? If not, use a label instead. Create a user control, place the fields where you want them and then put that user control on your form. Inheriting from textbox is the hard/long way around.

Hello,
Yes, you are right. Only labels are needed.
I am thinking of creating a user control using a panel to hold the different labels.

That would be the easiest way to do it.

I have been working with a fair number of .VOB files (DVD format) that are up to 1 GB in size. When I use "delete" from Windows Explorer (or xplorer2) or "rm", it takes a very long time to delete the files. I have moved all the files I want to delete (and the directories they are in, into a single directory, and looking at it, I see there are over 40 GB of data to be deleted.
I thought I would write something that would run as a service or if not that, at least invisibly, to handle the job by watching for files to show up in a particular director, then deleting them at leisure.
However, in playing around with VB, I have discovered that I can programmatically delete files very quickly.
The way I do it is to open the file for write, then close it immediately. This makes it 0 length. I then close it, then delete it, and the job is done almost immediately.
My question is this... Is this method viable? Does Windows fix everything up later, taking care of deallocating the sectors, etc.? If so, what the heck is taking so long with the regular file delete from Explorer or a shell?
What pitfalls am I overlooking?
Thanks,
Larry

Yes.

Perhaps a VERY fragmented volume. Try running Defrag on it once in a while.

I recently defragmented all my drives, but I rechecked just to make sure. The Windows defragmenter (in System Tools)tells me I don't need to defragment.
I just did a couple of tests on some .VOB files, using the rm from WinXs, and the files, sizes, and times to delete were:
vts_01_2.vob 1073739776
vts_01_3.vob 1073739776
>elapsed rm -f VTS_01_2.VOB
rm -f VTS_01_2.VOB
Elapsed time: 00:22:27.609
>elapsed rm -f VTS_01_3.VOB
rm -f VTS_01_3.VOB
Elapsed time: 00:09:18.047
I timed these with a little command line utility I wrote. It's quite accurate. Note that rm does not use the Recycle Bin.
I am at a loss as to why this should take so long, as well as why the first one took over twice as long as the second one.
When I delete files from VB, using the method I asked about (open for write, close, delete), a directory containing 4 or 5 of these files takes only seconds to delete.
Any ideas?

This gets weirder. I thought perhaps I'd try a DOS 'del' command, and came up with the following:
vts_01_0.vob 167813120
>elapsed del vts_01_0.vob
del vts_01_0.vob
Elapsed time: 00:01:39.203
So I retried the rm command supplied by WinXs, with the following result:
vts_01_5.vob 91742208
>elapsed rm -f vts_01_5.vob
rm -f vts_01_5.vob
Elapsed time: 00:00:49.016
Which is a quite acceptable time, and a far cry from the 22+ minutes I have experienced, though still much slower than my Open/Close/Delete method. I decided to try it again, and got:
vts_02_1.vob 125822976
>elapsed rm -f vts_02_1.vob
rm -f vts_02_1.vob
Elapsed time: 00:00:59.859
Still quite acceptable, but I think I'll keep on working on my DevNull program, which will delete anything dropped into a particular directory, and do it quickly.
I am now wondering if it has anything to do with the occasional slow launching I am experiencing. When it happens, I launch a program, the hourglass shows up briefly, then nothing happens. If I launch a few more programs, the same thing happens. After a few minutes (2, 5, occasionally more), al the programs I tried to launch will suddenly show up. I am running XP, Service Pack 2. I have Service Pack 3, but have not installed it yet.

Man, your machine's got issues. I'd try looking at virus problems next. That's the only time I've ever experienced that kind of time deleting a file.

Thanks for the help, Dave. I haven't yet figured out why my file delete is so slow, but you are probably right in it being a virus or other malware, or perhaps just a corruption somewhere.
At any rate, I have finished my "DevNull" program, and it deleted all the stuff I wanted to get rid of (about 30GB) in about 5 seconds flat, and that's with debug stuff and a dirlist and filelist updating on screen. The time taken seems to depend on the number of files and dirs (and the depth of subdirs) rather than the size of the files.
A directory with 1.25 GB, 168 folders, and 2881 files, took about 19 seconds. Definitely solves my immediate problem.

There are several ways of creating charts in Visual Studio.
1. You can use third party tools such as Dundas Chart[^]
2. You can use Excel as your friend said (I personally prefer Excel, as it is easy to use compare to Dundas Chart )
3. If you have enough time and willingness of learning something new then, you can create your own graph by using 2D image library in .NET (This involves lot of hard work but it is so worth learning)
There is one artical on CP explaining how to use Excel from Visual Studio but the author has used J#, but then again it is .NET so you can workout things in VB. Here's the Link http://www.codeproject.com/KB/office/JExcel.aspx[^]

Hi Thank you for ur answer,actully now i installed vb 2009 professional ,so i think it has dundas on it,so i wonder to know how i can connect my program result to report result?should i make an excel file or acces file or can directly use my program out put for it ,in fact my program calculates some parameters and i see them with this command:" consolewrite"so would you plz tell me how i can draw a graph with it?

It will take me hours to write everything on how to use them. You can just Google it and it will give you more information than i can.
And yes you can use Access database for Dundas chart, you don't need to transfer anything to anything...

Hello..
I am looking for some code (VB.net) so that i can see what my external (ADSL) router IP is. It would also be great if someone knows how i could also email this to myself daily? as i dont have a static IP with me isp.

People at this site do not usually just hand out code if you are not willing to work at the problem.
|
|
|
|

You'll have to write the code to query an external website for that information. The site has to return the IP address, such as http://www.whatsmyip.org[^]. There's no API cann you can use to get this information.
|
|
|
|
|
Hi,
this[^] may be
what you want: it returns just the IP address, no more, no less.
A simple code snippet based on WebRequest/WebResponse could get it programmatically.

Hello
I want to let my Vb.net program to let me view a specific channel of my usb receiver.
Please give me at least a hint to begin my research
Your will be greatly appreciated
And thanks in advance

You'll need a Software Development Kit for the reciever. The best place to find that would be the manufacturer of the receiver. Don't be surprised if they don't offer one.
|
|
|
|
|
I have all the file of the receiver in the Install CD
but i don't know for what to search and what to ask
Thank you in advance for your help

There might be something that says "SDK" on it, but I doubt it. Manufacturers don't normally ship SDK's with their hardware. You normally have to go to the manufacturers website for that.
