I suddenly got this message: There is no source code available for the current location when I run my application under debug mode. However, when I run the released .exe, it runs smoothly. The error occured even for something like Dim abc as String Thank you in advanced for any idea and...

Let's say I've loaded a treeview like this: - A |-A1 |-A11 |-A12 |-A2 |-A3 Let's say I want to add a child to A11. I can do it by: nodes(0).nodes(0).nodes(0).add("text"). I've tried to make it simpler by doing something like: Dim tNode as New Treenode tNode =...

Is there a pure .Net way to connect to a firewalled database server (in this case, MySQL in Linux, where connection can only be done through Linux socket). What I currently do is to run an intermediary application first, such as Putty or Plink to open up an SSH connection. Thank you.

To combat software piracy, I've decided to try dongle protection. I've bought the trial kit and found out no source code given but the API. Using API is ok, but what comes to my mind is... the API can be easily replaced by a fake API. For example, let's say the API is called dongle.dll. And...

I read a few article suggesting the use of var = Nothing when the variable is no longer needed. What about in cases like this: Private Sub Temp() Dim myString As String For i As Integer = 0 To 10 myString = i Next myString = Nothing End Sub To be clear, I am confused whether to call the...

I am new to StringBuilder. Commonly, I would write my code like this: Dim myString As String For i As Integer = 0 To 10 myString = i 'some other codes go here Next But if I want to change MyString to StringBuilder, how should the code myString = i be? Thanks for helping.

I learned that using EXIT statement is best to be avoided. However, I do not see the way how it should be implemented without putting so many codes to replace the EXIT statement. Given a very simple example for a save button procedure: if user types nothing notify user that nothing is...

I am trying to print "Hello World" on an A4 paper. I need it to be 1 inch from both top and left side of the A4 paper (e.g: x=100, y=100). I manages to do that on my printer. The problem is, on another printer (different brands mostly) there is a few milimiters difference, which is not...

To catch any errors in my app which is not within the Try...Catch...End Try block, I put this in the Sub Main: AddHandler Application.ThreadException, AddressOf OnThreadException which redirects the error to: Private Sub OnThreadException(ByVal sender As Object, _ ByVal e As...

I just learned to create DLL. When I add the DLL as reference to my new project, the DLL is copied to the application directory (bin). Let's say, I want to put all DLLs (for the project) in one specific directory instead of the application directory, how would I do that? Any help, idea or...

Let's say this is the XML file: I know how to read XML file. But how to change the <DefaultFont> value, for example from Arial to Times New Roman? And howto change the <Brand Name="Epson"> to <Brand Name="HP">? I have another problem with XML, but I will do it in another thread later. Thank...

I found this code for ASP .Net but I can't implement it in VB: I cannot find the equivalent one in System.Windows.Forms... I am trying to find a function to prevent sorting on certain colummn only. i.e the first column where it is numbered as row numbers. Thanks.

[Resolved] Datagrid: Row Highlight I am setting the datagrid RowHeadersVisible to False, and ReadOnly to True Whenever user clicks any cell in the datagrid, how do I highlight the whole row, or change the background colour of the whole row? Thank you.

This is not about programming actually. It is about how a group of programmers work together to build an application. In my environment, task or modules or forms are distributed between programmers to complete an application. The big problem is, it is very hard to control them. Currently, every...
