    - TreeView Question I know I can do this to populate a treeview Code Snippet Dim node1 As TreeNode = Me .TreeView1.Nodes.Add( Me .unitnumber.Text) Dim node1a As TreeNode = node1.Nodes.Add( "Gross Weight" ) If SRow.grossweight Is Nothing Then Dim node1aa As TreeNode = node1a.Nodes.Add( "Not Specified" ) node1aa.EnsureVisible() Else Dim node1aa As TreeNode = node1a.Nodes.Add(SRow.grossweight) node1aa.EnsureVisible() End If Dim node1b As TreeNode = node1.Nodes.Add( "Laden Weight" ) If SRow.ladenweight Is Nothing Then Dim node1bb As TreeNode = node1b.Nodes.Add( "Not Specified" ) node1bb.EnsureVisible() Else Dim node1bb As TreeNode = node1b.Nodes.Add(SRow.ladenweight) node1bb.EnsureVisible() End If But how do you go to a table and load a treeview by using columns and text combined I am wanting to show the following Unit1 'would be column "unitnumber" - Gross Weight 'would be a label - 1000 'would be column "grossweight" -Laden Weight 'would be a label - 700 'would be column "ladenweight" Unit2 'would be the next record - Gross Weight - 1820 -Laden Weight - 1100 Itenerating through the table is where I am losing it Any thoughts appreciated Davids Learning Tag: bitmap to Picturebox throught network

    - Horizontal Scroll Position Changes I have a user control with a Panel. At runtime I add some ListViews to Panel.Controls. (I have to add them in the reverse order that I want them to display. Is this normal ) I add a splitter between each of the ListViews, and all the controls are Dock.Left. After the controls are added, I change the width of the Panel so that it is about twice the width required to display the ListViews. This is so the user can change the width of individual ListViews. The problem I have is that when the form is first opened, the Panel is scrolled such that the last control -- actually the first added but the last in the sense that it is the right-most control -- is visible. If I scroll the panel so that the last control is no longer visible, then cause the form to lose focus, upon regaining focus the panel scrolls so that the last control is once again visible. What I would really like is for the Panel's Horizontal scrollbar to start at it's left-most position, and then stay whereever the user puts it thereafer, even after focus changes for the form. Any assistance would be appreciated. Thanks. Tag: bitmap to Picturebox throught network

    - Get print tray media We print most of our documents to plain paper, but have some that must print to perforated paper. We have the bins for the perforated paper set to a type of "pre-punched" to differentiate. (this setting is similar to setting one bin to letterhead). How do I get that media type setting for each tray on a printer so I can tell which tray to print each document to Tag: bitmap to Picturebox throught network

    - CliickOnce : Manifest may not be valid I've been using ClickOnce for about year now (and regretting it), here my latest problem. I've deployed my app on about 20 PCs, and they working fine apart from one, it won't update to the latest version, it gets to about 25% and then says it can't continue, the details suggest for one of the DLL files: The manifest may not be valid or the file could not be opened. Once again, this does not happen on the other PCs. Heres what I've done so far: uninstalled completely, deleted the cache (app folders in the users profile), ran mage.exe -cc to make sure, but still no change. It also says the xxxxxx.dll is not a valid portable Executable (PE) file...but it seems to be on the other PCs So, before I format the hard drive and re-install windows, is there another step I can take to resolve this problem Maybe a registry entry I can delete. Thanks in advance, Scott Tag: bitmap to Picturebox throught network

    - Setting Today's Date by Default in a Function I have a function that converts a date into a date "code" for my customer (i.e. January = "A", February = "B", etc). Ideally, I want the function to convert a passed date, but if no date was passed, just use today's date. I started with this: Public Function DateCode( Optional ByVal DateToCalc As Date = Nothing ) As String ...but the problem is that when I don't pass anything, the date is still set to "something", namely: " #12:00:00 AM#". I can't set the default value for the optional variable DateToCalc to "Now.Date", as it gives me an error "Constant expression is required". I tried to verify that this was not a valid date like this: If Not IsDate(DateToCalc) Then DateToCalc = Now ..but this is still "OK", because it is technically still a date/time. I realize that I am probably missing something simple [stupid] and I would appreciate any suggestions. Thank you. Tag: bitmap to Picturebox throught network

    - An attempt was made to access a socket in a way forbidden by its access permissions This is gettting rediculous. My application was working quite well until I ran into the database problem I ask about in a previous post. I tried to solve that problem by reformatting my hard disc and starting from scratch with a virgin copy of vb express. No joy. I solved the problem by getting rid of the databases and putting the data in the code. Before all this happened, I was able to use "click once: to publish my application to the web. The first time I tried to publish after the new copy of vb was installed I had trouble with signing the application, something I had not encountered before. I added a test certificate to the the project and tried again. Now I get the error message which is the title of this post. Since it is the compiler code that is trying to access the socket, I have no clue as to what is happening or how to fix it. I can find lots of stuff on the web about this error message but it all has to do with ASP, nothing about "click once". I am the adminastrator of this machine. I log on as the adminastrator and I work with it as the adminastrator, so I don't understand how I could have "permission" problems.
