I searched on the forum / Internet for the solution how a PropetryInfo object (of a Public property) can reveal if it has a Private Protected Setter ... it was all in vain .... all help I found was about how to "Set" value of a public property having a Private Setter.I would like to know if I have a PropertyInfo object of a public property, how would I know if its Setter is Non Public?
I tried, in a exception handling block, where I did a GetValue of the PropertyInfo object and then called SetValue by setting the same value back... but to my surprise it worked well and didn error out.

I am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.

I want to type the characters from right to left (to behave as a right alignment). But I am not supposed to use the Right Alignment property or the RighttoLeft property of a text box.For example, I want to enter the characters of a string from right and each character should shift one space left so that the user can enter another character after that.

View 4 RepliesI'm recreating a program (don't ask - it is embarrassing) in Visual Studio 2005 VB where I read a spreadsheet in an then select values from certian rows. I added the Interop reference and the MS Excel 14 object library, but when I type something like:
Public oSheet as Worksheet
...
x=oSheet.Cells(Row,1).Value.ToString
I'm concerned because when I type the period after the ) it does not allow me to select value. I type it in and it does not give an immediate syntax error but I'm guessing that when I try to run this, it will fail the build. Is there an other reference I need to add or do you get the value of a field differently for Office 2010 than we did for Office 2007?

There is no BackStyle property in Visual Basic 2005 ... But I read in MSDN that changing the BackColor of label control will make the background of label control Transparent ... So we'll be able to see through the label control ... I changed the BackColor property to Transparent but it didn't work for me ... BackColor changed to Transparent ... But still I ain't able to see the image behind the label control ... (PictureBox) ... Background color of label still remained the background color of Form i.e. Control color ...
View 6 Repliessome controls(e.g. buttons/labels) dont have a drawmode property. Im looking to create buttons with rounded corners because they just look nicer :P. Now, the problem is that even when you have a custom paint event, the button just gets drawn first and the custom paint event will draw on top. Especially with rounded corners, where you see the parts of the default button in the corners. Is there a way to only execute the custom paint event / block the default paint?

But it gives me the following error: ExecuteNonQuery: Connection property has not been initialized.
In the application I'm documenting, sometimes a value is stored in a Public variable & other times it's passed to/from a Public Property which does nothing except store it in/retrieve it from a Private variable. (And in one memorable exception, the Public Property stored it in a Public variable-I'm almost certain that was an oversight by the original programmer though.)
I know that passing it to/from the Public Property has the potential for better validation, but if the Property doesn't actually do anything except store/retrieve it is there any benefit to declaring it as a Property? (Or maybe I should put that the other way around. Personally I'd declare them all as properties because that will allow adding validation later-but I'm not rewriting this, I'm just trying to document it and, in this case, trying to figure out why sometimes it's done as a property & sometimes as a Public variable.)
I have a wrapper class created around TextBox, and I want to find out if there is any way to test if the vertical scroll bar is at the beginning (the very top) of the text box and at the very end of the text box.Alternatively, I will be happy if only I can find out a way to check if a scroll bar is enabled or not in a textbox (note: it's not a RichTextbox).
By enabled, I mean that scroll bar is actually enabled i.e. you can use the scroll bar to scroll the control, not just visible (I know we can check visibility by GetWindowLong)
I'm adding a method to find and select text in my text editor. Everything worked fine, including the ability to find all instances of the text. My problem came when I tried to make it more user-friendly (doesn't it always?). Originally I had only a menu item with a shortcut( Ctrl + F) which invoked an input box.
Then I added a textbox and a button (similar to that seen in a web browser's Find() method) that calls the method in the same manner as the Find/Replace menu option and displays the desired text in the textbox. Everything works fine except that the text is not selected. I have MessageBoxes displaying the values of required variables in 3 places (marked ***FOR DEBUG ONLY***) to make sure that no values are being changed, but all variables are the same. The method still locates the text, but it is not highlighted.
I think it could have something to do with which object has focus. (When I click the button, the selected text loses focus?). But if I click everything with the menu items, it still works...
