I am writing a utility and using the ftpwebrequest. I am wanting to add a progress indicator to help the user know about how much time is left on the upload.

my final year project title is monitoring weight changes in digital scale / indicator.i bought one digital scale online from A&D in order to test out my system.however unlikely other device (GSM MODEM, RFID...) there are no drivers or libraries (DLL) from this device.. with only the digital scale and (rs232 9-pins to usb convertor i bought) i was like lost wondering how to get communicate with the device.i have been search around in the internet for similar post.. but there are most likely dealing with the data receiving already. is there any journals or manuals for references? i willing to study over this and not simply ask for full codings.
- how to communicate with the device (serial port communication)
- is there any driver / libraries need to install bfore everything?
OS using - windows 7 ultimate (laptop)model of device - A&D JM-SERIES 150lb

View 1 RepliesI am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.
How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.
I am using this code currently without the start and end bits

I'm using VB 2008 and windows vista. I'm using a listview in my application.(view=details) I assign an image list to listview.smallimagelist. when user try to sort the listview by clicking the column header i use the imageindex property to set an icon for that column header, this works fine. When user clicks another column to sort the listview by that, I use listview.columns(PreviousColumnIndex).imageindex=-1 to remove the sort order icon from the previously selected columnheader, but it does not remove the picture from the previous columnheader. How should I remove the icon(picture) from the previous column header?
View 7 RepliesI have a tab control (in my case a UltraTabControl from Infragistics) and I add a new tab.
The text of this new tab is set to "Escape &Characters".
lTab.Text = "Escape &Characters"
When visualizing the tab control the & will become an _ (underscore) for the next character - in this case "C"
I know that & is the Microsoft way of indicating a shortcut character - but is there any way of disabling this behaviour?
Does somebody know where i can get Microsoft's status indicator bar animated image that has a progress bar on it that when it reaches the maximum it goes the other way round.
You can find a small version of it in :c:Program FilesMicrosoft Visual Studio 8Common7VS2005ImageLibraryVS2005ImageLibraryanimationsstatus_anim.gif and it is called
"Indeterminate status indicator bar".
After a long time searching, I am still facing an issue with my listview column header I am trying to add a sort indicator (a small 16x16 arrow, next to the column title - looks quite good).
- My listview is in Ownerdraw mode for : Items & Subitems for a couple of reasons
- So far, I was letting the system do the job for the header (e.drawdefault = true)
I managed to add very easily the arrow using the e.graphics class, right after the e.drawdefault=true, and it is actually working good.
print01.gif
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, 34, 2, 16, 16)
As you can see, I'm simply using a resource, and am forcing it to 16x16 with a custom location x=34 pixels y=2pixels My issue comes with the following :
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, (e.Bounds.X + 34), 2, 16, 16)
The arrow wont draw Of course the sort indicator will sometime be on the 2nd column etc.. That's why I need to use the column header's bounds.I can already hear you saying : if you do not owner draw, you can't..But why is it working with a static location (, 34, 2, 16, 16) ans not starting from another static location (e.bounds.x) How can I fix that ? I cant find previous issues similar to that one over the internet.
Points of interest :
- I tryed to load the int value e.bounds.x into a variable before, using that instead of e.bounds.x but it's all the same.
- Using the imagelist is not an option, As you can tell from the screenshot, I am already using images for headers.. the sort indicator is coming as another image
- Using ">" or "<" in the header's text is not an option either........ (sorry pal It does not look good at all..)
- Drawing the header totally in owner draw mode would be an option, but it looks quite hard to do (need to manage the "rounded" header style of the system, the mouse over - small yellow line rounded on the sides in WinXp, the click effect....).

View 1 RepliesI have been given a project to update software written in Visual Basic. The software and some files are enclosed in a folder and was written 3 years ago. I have no clue what to do. All I have been asked to include more controls. The user interface allows user to select three processes by clicking on the buttons on user interface. The new requirements is to add two more buttons. There is not much information so I have to use only the resources available. When I tried to open the project, visual studio prompted to convert the project so its compatible with current version. I could open the project but dont know what to do from there. Please guide me towards the right direction. If the project folder is required please advise me how to attach it too.

The mechanism works fine, but I want to add a progress bar to follow the progress of the files in the queue: processing 1 of 10......2 of 10......3 of 10 etc.For testing, I created a batch file to simulate the creation of files, so the filesystemwatcher can to his work and place the files in the queue. When I tell the batchfile to simulate the creation of 20 files, I see that the amount of files in the queue change. For example;

In the app I'm currently making, I have two progress bars. One for current task being committed and the other is for overall progress.During runtime, I calculate how many tasks are being run and set that as the maximum. As each task completes, the progress bar is incremented by one.
I want the current task progress bar to show the progress of the current task. Some tasks can take a few minutes to complete so that progress bar works great. But, if the task is super quick, like editing registry keys, I see no progress at all.When I edit the registry, it basically goes like this:
'Edit Key
'x
'x
'x
ProgressBar1.PerformStep()[code].....
It completes so quickly that I never see the bar even move.I also have each task report its name into a label and it skips ahead so quickly that I only see the first task name and the last.Is there any way to make this do a better job at reporting the progress?
I came across a problem in my program it takes too long to calculate the values needed (about 10 sec) .But thats not the problem you don't know when the program is working or not, as it just locks up until its finshed and I view that as a problem.
I need to be able to show the progress of this .I looked at using background Workers but I get exception "Object reference not set to an instance" I believe this is because the background worker cannot write values or something ,As it works will a normal handler.
