Why?? The jobs will queue up on each machine until the printer is no longer busy with the previous job. Then, it'll print the next job in the queue automatically.

Again, why do you need the status of the printer?? It's rare that anyone would need this.

I've asked this before, but just in case it was missed, I thought I'd ask again.
"I want to emphasize the relationship of some adjacent Cell Rows in a Column, by Drawing a 2 or 3 Pixel Line around the Group of Cells.
I read that the Microsoft DataGridView Control does not support the Individual Cell Border Style in the Current Version.
Does anyone have a routine, or suggestions that will achieve this result with the MS DataGridView Control."

You could use the OnPaintCell event to give them a common background colour.

Thank you Henry.
If I'd wanted to know about BackColor I would have asked that question.
The question was about Drawing a line!

You also asked for other suggestions.
I made one.
Sorry you didn't like it, but there was no need for you to respond, if that was the case.
Good Luck!

I need to populate a DGV. I need to be able to index the rows of the DGV by a string variable. But I also need to have duplicate rows in the DGV. A collection allows me to index the rows the way I need to, but doesn't allow duplicate keys. Is there any other alternative?
Thanks

Hi,
what collection are you using?
some of them (such as List) don't care about unique items, others do (such as Dictionary which requires unique keys).

Hello,
Dim Mycollection as new collection
Are you saying I should be looking into List(of)?
Thanks!

you should ALWAYS use typed containers.

if you're using a hashtable, you can make the key map to a list of items, then you can add duplicates there.

"Make the key map to a list of item" sounds like what I want, but how?
I map my collection (maybe a hashtable) to the DGV
Each item in the collection represents a separate row in the DGV
I write to the collection through the key. Ideally, more than one row could have the same key and would all be written to in the same set.
But collections, hashtables too, require unique keys.
What am I missing?
Thanks again.

You could create a Dictionary< string, List< someThing>> which would map each string onto a List holding zero, one, or more objects of type someThing.

Hi everyone, im working on the GCS part of our autopilot project. I have developed it in visual basic.net 2005 , what the software basically does is that it receives the values byte by byte, convert them into type double and then displays it on the gauges attached in the design window, im attaching my code below, can someone please tell me if whatever i have done here is correct ??

What does 'correct' mean ? Does the program do what you expect it to ? What sort of advice are you looking for ?

I have Notepad in my machine and it is my default text editor. When I double click a text file in Explorer it automatically opens in Notepad.
I have made a similar program. I have compiled it. It reads text files properly. I have published it and made a setup file. I installed the file.
I opened it, opened a text file manually, it opened. I assigned it to be my default Text editor. Now I double clicked a text file and it just did not open at all.
Please tell me how to get this thing done.

I am not sure if I understood your question correctly. Are looking for FileAssociation? Then, this[^] or this[^] article can help you.

Just as another note, Windows passes any files to be opened as command line arguments. If you get any arguments which pass file paths (ie System.IO.File.Exists returns true), then you need to open them

Does your application handle command line arguments and handle them correctly?? I'm guessing probably not. That's how Explorer tells your app which file was double-clicked. The command line it would use to launch your app would look something like:
C:\Program Files\MyApp\MyEditor.exe "C:\some folder\some other folder\folder\MyTextFile.txt"

Take a look at this[^]. It contains code snippets and a demo porject project ( I really must learn to type ).

Hello -
I am trying to open up an excel file. I am writing this from a Ribbon Command Button using VSTO. My main goal is to open an existing file (\\musabiralo\musa.xls).
When I try this, it opens up in a new Excel Workbook, not too surprised but what I really want to open on existing workbook. Question is how can I do that?
Dim xlApp As New Excel.Application
Dim xlsWB As Excel.Workbook = xlApp.ActiveWorkbook
xlApp.Workbooks.Open(fileFullPath, , True)
xlApp.Visible = True
Thanks a lot.
