Recently I've found how to add a link to an item in Visual Studio so that you can reference common or shared files between projects. Editing the original propagates the changes to the projects where the file is referenced. But you can also edit the reference item and the changes are reflected in the original file, is there a way to prevent this behavior?
View 1 RepliesI'm supposed to create a linked list and add/remove items with a push/pop. Currently I can only push 2 items and pop one before it stops, and I'm not sure what I need to do to fix that.

i've tried the enabled propreties to disable editing combobox iteam but it make it gray and it become unreadable.so i changed the combobox style to simple (it looks like a texbox) and i want to know how can i prevent user from changing the content.
View 4 RepliesI am currently editing a big mass of items, which is taking very long to do. Even loading up my Treeview from a file is faster. What I currently have is this:

Private Sub IncrementTreeviewNodes(ByVal Position As Integer)

treeMeshList.Nodes(Position).Text = "Mesh #" + Position.ToString
Position += 1

I've got a RTB that I use to display some info for a user. Scroll bars on the right to move the data visually up and down.
I don't want to allow the user to alter text in the RTB - it's for display only.
How would I go about that without using ENABLE=FALSE?
I have a vb.net program that allows you to access webpages in my localhost. Now, my problem is that, when I try to list records in mysql by using tables, it remembers history and the previous data that you listed will appear like a ghost even if the data you inputted does not correspond to the data that it is showing. How can I avoid that?
View 1 RepliesI want to update some things on the form when the user clicks a new date (or changes the month, which automatically selects a new date). If I use the DateSelected event, it seems to work as expected when I use the mouse. However if the arrow keys are used, the event does not get triggered. If I use the DateChanged event, it seems to go into an infinite loop. The message box pops up a zillion times when I click the arrow to change the month:
Private Sub MonthCalendar1_DateChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DateRangeEventArgs) Handles MonthCalendar1.DateChanged
MessageBox.Show("DateChanged")[code]....
The only problem with using the DateSelected event is that if the user uses the arrow keys, the event is not fired. I thought I could fix this by disallowing the use of the arrow keys, but I couldn't find anywhere to do that.
The message box shows up, indicating I have selected the enter key, but a return is also aoolied to the rich text box.[code]...

View 5 RepliesI have a webbrowser in the form, ele is a HtmlElement on the page in the browser. now, I want to get ele's value (if it exists). if I turn off option strict, then
If (ele.DomElement.value() IsNot Nothing) Then

this works. but if I turn on option strict, then it has error for "disallow late binding".
I guess I should use ctype to convert ele.domElement, but what type should I convert it to? htmlelement will not work.
I want to disallow changes to two comboboxes unless the user first clicks a LOCK symbol on the screen. I pop a Y or N into the tag of the picture box when they click it...I've got this - combobox is called LanguageTo

After reading through several forums, which suggested that I should add a referenced DLL (whose source cod I have) to solution as an added project, I am unable to step through the code of the referenced DLL that generates an error. I also turned off"Enable just my code" from Tools->Options-> Debugging. However, I am still not able to step into the referenced DLL's code I added the pdb file and the referenced dll to the bin/Debug folder of the original code that I am working on

View 2 RepliesI have a large number of MS Access databases that I'm automating to relink tables. However, there is one table that can't be relinked normally as Access says it has too many indexes. A manual work-around is to link to the view in SQL Server (2000/2008) and rename that table.Now, I want to do this programatically (I'm using DAO to relink the tables, which works nicely). I've been looking at CreateTableDef, but I don't know if this is the right way of going about it. I don't want to hardcode 260+ fields that may change (this is the main table from a 3rd party vendor, so I have no control over the fields in this table, or any normalization for that matter, but that's another topic...).Also, 98% of the tables being changed are Access 2000/2003 tables. The other 2% are Access 2007/2010.[code]

I have the following projects:
TradingProject (my code) Has reference to TradingLibrary, and to ApiLibrary?
TradingLibrary (my code) Has reference to ApiLibrary
ApiLibrary (3rd party code)
I'm making several projects (like TradingProject) that communicate with a software through use of an existing ApiLibrary. But I want to push generic methods into a library I write: TradingLibrary.
Still, I would like to use some parts of the ApiLibrary directly from TradingProject. However, I then would need to pass an object (of an ApiLibrary class) into a method in TradingLibrary. Where the object should be recognized. However I assume this will be a problem, as TradingLibrary use it's own reference to ApiLibrary, so it will not be recognized as the same classes? Is there some way I can "forward" the ApiLibrary reference from TradingLibrary to MyProject, such that they will use the same reference? Or do I need to duplicate the classes and inherit from ApiLibrary for each class? Like:
NameSpace TradingLibrary
Public Class SomeClass
Inherits ApiLibrary.SomeClass
End Class
I guess that would work, if I do it for all classes I need, but is there perhaps some simpler way I'm not aware of?
I'm co-developing a vehicle information system that reads and presents data from a communication bus. Signaling information on the bus is stored on some kind of database (from the dark ages i'd guess) from which it's only possible to get data out of by extracting a xml-snapshot. Since that wasn't bad enough, someone in upper management thought it was a great idea to treat different parts of the system as different projects (it looked really nice in the organizational chart) which lead to more databases...It is now my responsibility to merge these xml-files into one and before I start banging my head against the wall i thought it would be a good idea to check with you geniuses if there's any neat solution to my problem.The structure of the xml is somewhat like this:
<data>
<frame ID="1001">

I have been using Excel in vb.net for years and no problem but I have a new app and nothing is working. First I can't get Microsoft.office.interop referenced anywhere, which was weird. Then I can't instantiate Excel App.. Dim pExcel_App as New Excel.Application -- this gives me error "New cannot be used on an interface??But I can do this..Dim pExcel_App As New Excel._ExcelApplication -- where did this come from?Then I can't put anything into cells Dim wkbSheet As Excel.Worksheet wkbSheet.Cells(1,1) = "Title" --- this give me an error "Expression is a value and therefore cannot be the target of an assignment"
THe really weird thing is that I have an old app open at the same time that is just fine with all this code. AND the intellisense is different for each cell.The good one sets is as a range, the bad one says it is an object???I re-installed the MS PIA's but this didn't help.
I decided it was about time I learned about accessing Microsoft Office products via VB.NET. I started with Excel and it all worked fine, I could create a new Excel Application, open a workbook from file and read from the sheet then close it all down again no worries. However, when I turned to Word...things got strange. Using the code provided below, every time I run it an instance of Microsoft Word opens itself on the desktop (with no loaded content). I didn't have this problem when using Excel with similar code, so I have to ask..what gives? Is there a way I can stop MS word opening at all? At the moment it just flickers for a second (it opens when I open the document, then when I call the Quit method it shuts down a split second later)[code]...
