Not yet there though since i'm fairly new to vb.net Anyway: I need to print PDF files that are on disk to a network printer. I searched for some printing code on the net and found several similar approaches. However printing only seems to work to local printers, not network printers. Even on local printers it sometimes fails. I used the following code: Dim PD As New System.Drawing.Printing.PrintDocument Dim DefPrint As String = PD.DefaultPageSettings.PrinterSettings.PrinterName PD.DefaultPageSettings.PrinterSettings.PrinterName = .PrinterNaam Dim NP As New Process() NP.StartInfo.FileName = "c:\test.pdf" NP.StartInfo.WindowStyle = ProcessWindowStyle.Hidden NP.StartInfo.Verb = "Print" NP.Start() NP.WaitForExit(9000) If Not NP.HasExited Then NP.Kill() End If PD.DefaultPageSettings.PrinterSettings.PrinterName = DefPrint any way to improve this piece of code ? it launches the print command to acrobat, but maybe there is a better trick to do the printing. How comes this doesn't work for network printers ? Thanks in advance, Nick Tabindex Problems programmervb.netc++8-Aug-07 7:16 programmervb.netc++ 8-Aug-07 7:16  I am having a time trying to get my tabindex right on one of my forms. I have about 40 controls mostly text boxes and combo boxes. THey are all grouped inside of groupboxes and for somereason the tabindex does not stop on the text boxes just the combo boxes. Humble Programmer Re: Tabindex Problems Luc Pattyn8-Aug-07 7:39 Luc Pattyn 8-Aug-07 7:39  the tab order includes those controls that have TabStop=true; and it does that in order of increasing TabIndex. If, while modifying TabIndex with Visual Designer, you create a conflict (say you reuse a TabIndex value), Designer will adapt the other one silently. So you may want to check them twice ! Also I am not sure how it works for nested controls (as in a GroupBox); I expect there to be a "local" world of tab indices. Hope this helps.

I am wondering if it may have something to do with the type of controls on the form for exampe textboxes and Combo Boxes. Humble Programmer Re: Tabindex Problems Tom Deketelaere9-Aug-07 4:24 Tom Deketelaere 9-Aug-07 4:24  normally it should effect the tab order the only thing I can think of is that the controls ar disabled if that is the case the tab will not stop at those controls (but you probably knew that already) perhaps checking the tabindex property will clear things up a bit (make sure no control has the same tabindex) Re: Tabindex Problems i gr89-Aug-07 8:44 i gr8 9-Aug-07 8:44  in Menu There is TabOrder option select that it will shows the current tab position of u r controls , u adjust the taborder position and finally execute the programme then only u r changes will be accepted. unless u execute the programme u r changes will not get effect prabumj@gmail.com Updating a database when an application goes online steve_rm8-Aug-07 6:32 steve_rm 8-Aug-07 6:32  Hello, VS 2005 + SQL Server 2005 I have created a PDA application that uses typed datasets. It connects to a web service that is connected to a SQL DB. The PDA will sometimes be used offline, and the user will add, update, and delete the data on the pda. When the user goes online, how can I make the data that has been updated on the PDA be in sync when the user connects to the SQL db? There many people using the same database concurrently. Many thanks for any suggestions, Steve Re: Updating a database when an application goes online Kschuler8-Aug-07 7:55 Kschuler 8-Aug-07 7:55  You will have to write a method that checks every once and a while to see when the last sync was, and then sync again. You will probably have to create another table in your database that stores information about when different tables were last update or keep a history of the changes that have been made or something along those lines. If you can trust that the user will shut off the program before shutting of the PDA, you can do this sync check in the Load event of your first page. If you don't feel comfortable using that event, you could set up a timer control that runs every half hour or hour or whatever. Is this what you were asking? Entering new Address group in Outlook Express thru VB Xandip8-Aug-07 2:54 Xandip 8-Aug-07 2:54  Hi all, I want to enter some ids (4 or 5) into a new address group in outlook express thru VB. Can anyone help me out..?? Thnx in advance. The name is Sandeep Datetime/Integer error aqzman_8-Aug-07 1:27 aqzman_ 8-Aug-07 1:27  Hi guys, I'm having a pretty simple problem, but I guess I don't have the skill to solve it yet. I've wrote a string to get information from a database and put it into a label, all of that works fine but one of the fields is an Integer, and another is a datetime, so where I'm using "+"s it gives me an error, how can I solve this? Here is a shorted version of the line of code. txtMenu = txtMenu + "<tr>" + "<td>" + " User's ID " + usrid + "</td>" + "<td>" + " State is " + State + "</td>" + "<td>" + " Date Opened was " + dateopen + "</td>" + "</tr>" The HTML code is just for setting up a table, the error occurs between 'usrid' and 'dateopen', atleast, that's my best guess. Here is the exact error I get: "Operator '+' is not defined for types 'Double' and 'Date'.". Any suggestions would be a big help. Thanks, aqzman Re: Datetime/Integer error Tom Deketelaere8-Aug-07 1:38 Tom Deketelaere 8-Aug-07 1:38  use '&' instead of '+' in vb.net '+' has the math value Re: Datetime/Integer error aqzman_8-Aug-07 1:57 aqzman_ 8-Aug-07 1:57  Worked like a charm, I knew it was only simple. I tried "+ & usrid & +" too, haha. Thanks a lot for the help! Reply from Senthil.S for Datetime/Integer error Senthil S8-Aug-07 2:01 Senthil S 8-Aug-07 2:01  Hello, Their is a Traditional way, for all variable(different datatype). i,e.

Re: Determine whether there is select item in the list Luc Pattyn7-Aug-07 23:54 Luc Pattyn 7-Aug-07 23:54  Hi, depending on ListBox.SelectionMode you can use some properties: either SelectedItem and SelectedIndex or SelectedItems and SelectedIndices Luc Pattyn [Forum Guidelines] [My Articles] this weeks tips: - make Visual display line numbers: Tools/Options/TextEditor/... - show exceptions with ToString() to see all information - before you ask a question here, search CodeProject, then Google Re: Determine whether there is select item in the list Mekong River8-Aug-07 0:25 Mekong River 8-Aug-07 0:25  Thank you for your comment. But I do not want to know the selection mode. What i want is whether any item in my listbox is select or not. My list box selection mode is set to select only one item only. Thank you for your support Re: Determine whether there is select item in the list Luc Pattyn8-Aug-07 0:29 Luc Pattyn 8-Aug-07 0:29  as I said it depends on the selectionmode which two of the four properties I mentioned you should use.
